    How to: CPU and GPU usage along with FPS in-game

    How to: CPU and GPU usage along with FPS in-game

    Retired Staff

    I searched this forum and couldn't find a guide on how to have both GPU usage and FPS, which is something you can have nowadays with MSI Afterburner, along with CPU usage. I read many threads of people having to Alt-Tab out of a game to go look at the Task Manager CPU usage graphs to figure out if their CPU was bottlenecking the game or not.

    Well, there is a simple way to have all three, CPU, GPU and FPS (and many other parameters if you like) on-screen during your games. This is how to do it:

    1. Download and install MSI Afterburner if you haven't done so already;

    With Afterburner comes RivaTuner OSD Server, a standalone program that Afterburner starts and closes when you close Afterburner. For some reason you don't get to have the FPS on-screen with HWiNFO (see below) if you are running MSI Afterburner, so you need to only have RivaTuner OSD Server running. To do that you have to launch it on its own.

    For ease of use you can make a shortcut to it on your desktop.

    It is usually located in the following path:

    C:\Program Files (x86)\MSI Afterburner\Bundle\OSDServer\RTSS.exe

    2. Download and install HWiNFO32 or HWiNFO64. depending on whether your OS is 32-bit or 64-bit. I tried the 32-bit version on Windows 7 64-bit, and, while it does work, the game I tested it with, RAGE, did stutter a bit, so my advice is, if you have a 64-bit OS, install the 64-bit version.

    HWiNFO is a very nice program that has two functions: it acts as a CPU-Z + GPU-Z + storage information type of program, with a nice System Summary that combines the information in a very convenient way (it also has a more conventional style of presenting more information when you close that window), along with a full array of sensor readings.

    When the program starts you get to choose to go directly to, and only to, the sensors part of the program, which is what we need in this case, so check that box to make it faster:

    Now, as you can see, there is a full array of sensors and measurements:

    Although HWiNFO is showing all the parameters' readings, you can choose to monitor the ones you want by right-clicking on each item and selecting Enable or Disable Monitoring - that is the difference between the items with a red cross and the ones with a clock: the ones with the clock can be then logged to a file by clicking on the "Logging Start" button at the bottom.

    You also have to enable monitoring on the ones you want to be shown in the OSD in-game.

    To tell the program which readings to send to RivaTuner's OSD Server, you need to click on the "Configure" button at the bottom. BUT, before you do this, you must run the RivaTuner OSD Server program, otherwise it will show as "Not available" and the checkboxes will be grayed out.

    Now that you have RivaTuner's OSD server running you can finally click on the "Configure" button and select what you want displayed in-game. Don't forget to choose the line in which you want the information displayed.

    I have selected Core #0 - #3 usage on the first line, and then GPU Core Load and GPU Memory Allocated on the second line; the FPS will be shown on Line 3. The FPS will always be the last information displayed, as it is provided by the RivaTuner OSD Server (make sure "Show own statistics" option is ON in the OSD Server). This is how it looks:

    I chose to monitor each CPU core individually instead of the Total CPU Usage for a simple reason - Total CPU Usage is a false indicative of whether your CPU is bottlenecking the GPU. In games like Crysis for example, the game engine, although capable of using four cores, is optimized for two cores, so when one or two cores reach the 90%s utilization, your GPU will be bottlenecked and your frames will drop, even if your other CPU cores are well below 50% usage.

    If after checking your CPU usage you encounter one of two scenarios: one or two cores (in the case of quad cores where the game is optimized for two cores) are at 100% and your framerates and GPU usage drop when it does that, or if all cores are at 100% and your framerates and GPU usage drop likewise, you should try overclocking your CPU and see if it makes a difference. If the framerates and GPU usage increase, then you have a CPU bottleneck.

    Of course, there may be other bottlenecks in your system, like your storage and / or memory subsystem or Internet connection and / or the lag to the server you're connected to in multiplayer games. It can also be a memory leak in the game that leads to seemingly unexplainable frame drops, or the simple fact that the game's executable is 32-bit and is not Large Adress Aware and so has to constantly shift data from disk to RAM if in reality it needs more than 2 GB of RAM to work smoothly at the settings you are running it.

    Graphics processing unit - Encyclopedia Gamia

    Graphics processing unit

    A graphics processing unit (GPU ), also occasionally called visual processing unit (VPU ), is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the building of images in a frame buffer intended for output to a display. GPUs are used in embedded systems. mobile phones. personal computers. workstations. and game consoles. Modern GPUs are very efficient at manipulating computer graphics. and their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel. In a personal computer, a GPU can be present on a video card. or it can be on the motherboard or—in certain CPUs—on the CPU die. [1]

    The term GPU was popularized by Nvidia in 1999, who marketed the GeForce 256 as "the world's first 'GPU', or Graphics Processing Unit, a single-chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that are capable of processing a minimum of 10 million polygons per second". Rival ATI Technologies coined the term visual processing unit or VPU with the release of the Radeon 9700 in 2002.

    However, both cards were predated by Rendition 's Hercules Thriller Conspiracy card, which combined Rendition's Verite graphics chip with Fujitsu 's FXG-1 "Pinolite" T&L  chip into a single chipset in 1997, though the card's release was eventually cancelled. In turn, arcade games (often using multiple chips) had featured similar capabilities years before home systems, such as Namco 's Magic Edge Hornet Simulator in 1993 and Sega 's Model 3 in 1996.

    Best GPU For Gaming - 7 Graphics Cards and 6 Games Tested

    Best GPU For Gaming – 7 Graphics Cards and 6 Games Tested

    January 11, 2015

    Considering recent game releases and the extremely high GPU requirements, a few questions that crop up amongst gamers are: What’s the Best GPU for Gaming ?

    What graphics card should I buy. Nvidia or AMD. Should I get a reference model or get an expensive factory OCed GPU?

    Most of the questions above are very subjective. Depending on who you ask, most will lean towards a biased brand preference based on personal experience. As opinions will vary drastically, if you’re someone with limited knowledge on the latest hardware and video game requirements, you might get confused.

    Testing Methodology

    To be able to test graphics card performance and provide an accurate verdict to what the best gaming GPU is, I first need to provide a few standards and the reasoning behind my choices.

    Resolution and Preset Where’s 1440p and 4K?

    If you’re looking into getting a GPU for resolutions of 2560×1440 or above, you will need to be upgrading to the best single graphics card solution very often, turning down AA and settings further in the future or going SLI/Crossfire. When dialing up the resolution, very few graphics cards can keep up with newly released games and hold a steady 50-60 FPS + (which is one of the best experiences you can get with any fast-paced game) with no frame drops. I personally game at 4K but I know I’m killing my future-proofing even with a monster multi-GPU rig. For this article, we are looking to provide the best performance per dollar, but also future-proofing for at least 2-3 years in both the VRAM and power departments.

    List of Games Tested

    Picking a list of games was not an easy task. I prompted to go for a mix of the most demanding and a few newly released games. The games picked are only first person shooters and third person titles.

    You might be wondering why?

    If your GPU can run these games, it can run just about anything from MOBAs to Platformers and beyond.

    Third Person

    Drivers for both manufacturers are mature and all games are well-optimized. This will aid in eliminating any discrepancies in the deciding factors.

    Best GPU For The Money

    As mentioned earlier, I want to give the best recommendations for a future-proof graphics cards that can average 50-60 FPS with little to no effort across all current games while also having enough VRAM and power for a good 2-3 years in future releases.

    I’ve added a novelty in the testing procedure – the “$ Cost Per FPS” value below the benchmark results, or as most already know it – price vs performance. As prices may vary from country to country and GPU price cuts or sales may occur, I’ve created a simple tool to calculate it. Basically, you *add currency value number here* divided by FPS, so you can play around and calculate the $/FPS for any GPU even ones that aren’t tested. You can find the tool here .

    Here are a few of the cherry picked requirements for our GPU benchmarks:

    • VRAM. 3GB or above
    • Availability. Worldwide
    • Overclockability. 5% minimum (of reference)
    • DirectX Compatibility. 11+
    • FPS. 60 FPS or above (average) across all tested games

    The requirements are very strict but this provides a purchase that will have longetivity.

    Here are the prices that were used to calculate “$ Cost Per FPS”. the benchmarked GPUs, as well as their benchmarked overclocked frequencies.

    • GTX980 : Stock: 1216 MHz Overclocked to 1279 MHz – $549
    • GTX970 : Stock: 1178 MHz Overclocked to 1266 MHz – $329
    • GTX780TI : Stock: 928 MHz Overclocked to 1006 MHz – $489
    • GTX780 : Stock: 900 MHz Overclocked to 1266 MHz – $399
    • R9-290X : Stock: 1000 MHz Overclocked to 1050 MHz – $329
    • R9-290 : Stock: 947 MHz Overclocked to 977 MHz – $299
    • R9-280X : Stock: 1000 MHz Overclocked to 1050 MHz – $249

    I didn’t want to go too crazy on the overclocks as most of the cards were stock. 99.9% of the time, any GPU you pick should easily be able to overclock to the numbers featured above.

    Note. To be able to get the best performance out of your GPU, your build must be equally balanced especially in the CPU department. If you’re unsure that yours can keep up to the task, or are just curious, check out our best CPU article for more info.

    4.3 - 15 Reviews

    What is 4K Gaming?

    4K ultra HD gaming isn’t so much about the games themselves as it is about the hardware. Right off the bat, you should understand that.

    Yes, there are games being put on the market that are specifically designed for native 4K ultra HD resolution  as their ideal and while there are also older games that simply won’t work well on a 4K PC. However, the real meat of gaming in this awesome ultra HD resolution of 3840 x 2160 pixels really lies in the hardware you use to play all sorts of PC games designed with HD or outright 4K in mind.

    This is because if you already have a 4K UHD PC in hand, you can take almost any newer game, even if it hasn’t been developed to scale completely to 4K UHD graphics and simply upscale it so that it renders (usually) smoothly on a fully 4K screen. Of course, there are also games being sold that play best at 4K resolutions, are designed for 4K resolutions and can only be played on Full HD PCs if they’re actually scaled down to their lowest levels of detail.

    Thus, in simple terms, 4K PC gaming is all about having a killer UHD Monitor (or 4K TV that hooks up smoothly to your PC) and a gaming rig PC with the GPU, processing, connectivity and RAM hardware to handle playing the best ultra-detailed games at full-blown ultra HD resolution.

    However, this isn’t exactly easy to pull off and only very, very recently have graphic cards begun to emerge which are genuinely capable of managing 4K gaming at serious frame rates and detail leves.

    Best of all, the game hardware landscape has improved a lot since the more pessimistic days of mid-2014. If you read some of the content on the web that comes from mi last year, you’ll often hear about how you can only have 4K gaming at 30 frames per second or less, or how you need at least 3 or 4 GPUs running together to manage any sort of ultra HD gameplay at anything resembling a smooth flow of motion and decent detail levels. And then there was also all the talk of pricing and how ridiculously expensive UHD PCs are.

    Well, these things have changed quite a bit in the last year, and while 4K gameplay is still not nearly as affordable as normal HD PC gaming, it’s getting a lot cheaper than it was even 7 months ago. Best of all, the key manufacturers of GPUs, Nvidia and AMD have finally started kicking out graphics cards that can really chew up 4K resolution on most games at at least decent frame rates in high and ultra detail levels and at excellent frame rates in mid-level detail settings.

    This is a definite improvement over 2014 and GPUs like the latest GTX 980 Ti and Titan X from Nvidia or the new AMD Radeon 300x line and the Radeon 295X2 are not only solid at most types of 4K PC gaming, they’re also surprisingly affordable. All the more when you take into account that these new GPUs can work alone in a 4K PC. You no longer need to buy several graphics cards and hook them together.

    So what tools will I need to game at ultra HD Resolution

    For starters, all gamers who want to do their gameplay at full 4K resolution will need that most basic and fundamental piece of hardware: the 4K ultra HD display screen.

    This can take the form of either a 4K PC monitor, of which there are many available models now, or a 4K TV, which will come with a lot more connectivity options and a far more robustly noticeable UHD resolution clarity thanks to its larger size.

    Whichever of the two is the case, the display absolutely will also need either an HDMI 2.0 port or a DisplayPort 1.2 connection port built into it. This is crucial for running 4K graphics between the PC and the screen at a robust and smooth Hz instead of the 30 Hz offered by HDMI 1.4 ports.

    Almost any smaller, cheaper 4K TV from Samsung, Sony, Vizio or LG  will easily give you at least the HDMI 2.0 ports and some models even include DisplayPort 1.2 connections. However, 4K TVs, even small ones, will also cost at least $800 and that’s at a bare minimum.

    On the other hand, 4K monitors are a lot more affordable  and a number of models now well for well below $500, though not all of them include connectivity for HDMI 2.0, so this is something that you’ll have to check as you shop around. Additionally, if you can get your hands on a monitor with G-Synch technology built into it. You will not only experience smoother gameplay, the machine is also guaranteed to have compatibility with the best 4K video cards on the market, which come from from Nvidia

    Next up is getting your hands on a robust GPU and a solid processor. These are two of the most crucial parts of a clean, smooth gaming experience in 4K and we cover them in a lot more detail below.

    GPUs for Gaming your way to 60 frames per second

    The real holy grail of gaming in either HD or ultra HD resolution on a PC is managing to pull it off at very close to or even beyond 60 frames per second. This is what has been so difficult with 4K PCs since the possibility of gaming at this resolution even emerged and only now are GPUs emerging that can handle all those pixels fast enough to deliver the smoothness of 60 frames per second.

    The bottom line is that this simply isn’t easy to pull off and we have to give a lot of kudos to makers like AMD and Nvidia for having pulled off what they’ve managed. The temperature and power strains on a GPU that manages to refresh 8.2 million pixels 60 times per second are big and this is why even powerful graphics cards like AMD’s former flagship the R9 290 couldn’t pull off more than 30 fps on resolution heavy 4K games and even then would often heat up to a skin-frying 95 degrees celcius.

    Only recently have GPUs like Nvidias GTX 980 Ti, Titan X and somewhat older but still very powerful Titan Z emerged with the ability  to actually handle many UHD games like Crysis 3, Assasins Creed Unity, Battlefield 4 and Ryse: Son of Rome at speeds of up to or sometimes even beyond 60 fps. Furthermore, all of these are single GPU units, which makes their achievement all the more impressive.

    Then there are the newest AMD graphics cards. These can also perform admirably at 4K resolution and relatively high frame rates while managing to do it without running nearly as hot as used to be the case. The AMD Radeon 295X2 is one particularly powerful unit that regularly manages 60 fps even at high detail settings for many middle-weight 4K games and can come close to 60 frames even for really graphics intensive games like Battlefield 4.

    Then there are the new 300X GPUs like the R9 390X. which is also a very decent single GPU unit and comparable to Nvidia’s GTX 980 Ti in terms of processing power.

    Finally, and these are brand new, there are the AMD  Radeon Fury and Fury X cards. which are essentially the new flagship GPUs from AMD. Their performance in 4K settings is genuinely impressive and has even been shown to beat the Titan X during benchmark testing in some regards.

    These latter GPUs come with high-bandwidth memory (HBM) as an integral feature and due to its ability to run much better memory bandwidth than the aging GDDR5 infrastructure, they offer some of the fastest and most efficient single-GPU power available today.

    Another crucial thing to keep in mind about any of the above GPUs is their cooling requirements and power supply needs. For example, the Radeon 295X2, with it’s dual GPU architecture. comes with an entire liquid cooling and air cooling combo that your PC tower will have to make room for. Furthermore, it sucks up a monstrous 500 watts of power and you need to be ready for this with the right kind of power box.  The Titan X from Nvidia, on the other hand, eats up 600 watts of power and though it’s air cooled and much more efficient at keeping to a reasonable temperature, installing it means making sure that that heat gets funneled out of your PC tower and not into the rest of your internal hardware, where it can build up.

    Finally, the really hardcore GPUs and power requirements described above are all about gaming at the full 60 frames and at high detail levels. If you’re happy with enjoying your 4K games at medium or low detail settings or can manage at a slightly choppy 30 frames per second, your 4K gaming experience becomes a lot easier. AT these settings, even a couple of Nvidia GTX 970 units or possibly a single 980 will be more than enough.

    We’ve actually reviewed several of these graphics cards (or all of them, depending on when you read this) here at 4K.com and you can check out those review above on this same page.

    What to look for in a 4K Monitor

    4K monitors come in all shapes and sizes, and many of the latest models not only offer better than ever connectivity, they also cost less than they used to.

    For the time being, no UHD monitor is equipped to handle ultra HD resolution at more than 60Hz, so pushing your gamin to beyond that level is pretty much pointless for now. However, sooner or later, DisplayPort 1.3 will emerge in newer 4K PC displays and then GPU technology will have to catch up all over again.

    Right now however, 4K monitors for PC gaming have a couple of crucial requirements. For starters, make sure your 4K screen comes with at least a DisplayPort 1.2 port. This will give you your 60Hz refresh rate and all of the GPUs we covered above are built with DP 1.2 connectivity.

    You can also go for a monitor with both DisplayPort 1.2 and HDMI 2.0. Of these, there are only a few on sale as of this writing but they offer an entirely new connectivity option for high frame rate UHD gaming and they’re also useful for 4K movie/video streaming from a media box when it comes to market. However, bear in mind that the only GPUs which offer HDMI 2.0 connectivity so far are those from Nvidia, and only their latter models. AMD hasn’t yet caught up to this trend since Display Port dominates the PC market.

    The second major factor in choosing a monitor that’s good for gaming involves response time. You want the fastest you can get your hands on and this means going for a TN screen. These monitors offer the best grey-to-grey response times of as little as less than 1 milisecond and –best of all– they’re also the most affordable 4K PC displays on sale right now. The downside of TN screen however is that they also don’t produce the kind of rich color and off-angle viewing clarity that 4K IPS or IGZO screen manage. However, with IGZO and IPS, things not only get pricier, they also get slower since response times slow down to 4 or even 7 milliseconds.

    Finally, aim for a 4K monitor with either FreeSync or G-Sync technology built into it. These will match your screens refresh rate to that of your GPU and create a much smoother overall performance, regardless of the native GPU refresh rate. G-Sync belongs to Nvidia and is designed to mesh with its GPUs, while FreeSync is AMD’s technology and aimed at AMD GPUs. Of the two, G-Sync is generally the smoother performer.

    Whatever 4K monitor you go for, just make absolutely sure that it is not a 30Hz panel. These are common and very affordable, but what they give you in terms of price is completely ruined by the fact that they simply suck with 4K gaming. No matter how good the rest of your 4K gaming rig is, if your monitor is capable of only 30Hz, it will cause graphics to flicker and you’ll never get to enjoy the smoothness of 4K at 60 frames per second. This is no fun if you’ve already spent $1000 on a GPU specifically because it’s supposed to deliver smooth high frame rate gameplay.

    Some Recommendations for your 4K Gaming PC

    A full blown 4K gaming rig that’s built to truly handle high levels of 4K graphics at high fps is simply not going to be cheap. The high end GPUs we mentioned above all cost at least $400 (the AMD R9 390X) and as much as $1000 (the Titan X from Nvidia). And these are just your GPUs.

    Your PC monitor will run you to at least $400 for a decent TN 60Hz model, and you’ll also need a compatible power supply, motherboard, CPU and some seriously solid RAM, at least 12 and ideally 16 GB of it.

    Putting this all together for yourself will cost at least $2300 if you want to play 4K games at maximum possible frame rates and maximum possible detail. If you’re willing to settle for lower levels of 4K gaming, then you could probably put together a 4K gaming PC for just over $1000.

    A Word on Game Consoles

    While 4K PC gaming can be done at 60 fps with upscaled 1080p HD games and even some of the still few 4K 2160p UHD games out there, even if somewhat expensively, console gaming is a slightly different story.

    You can definitely play your favorite console games on a PlayStation or Xbox from a 4K TV and get great graphics and decent rendering at 30 fps with the TVs upscaling engine and the console’s HDMI 1.4 connection. However, if you want to aim for gameplay at 60 frames, you’re still somewhat out of luck.

    Most game consoles still just offer Full HD gameplay at 60 frames and their manufacturers are only now beginning to put serious consideration into the upgrades that would make both of the major game consoles on the market fully 4K-ready on the 4K UHD TVs that are growing steadily more popular. Basically, we probably won’t see serious advancements on this front for at least a few more months, until near the end of 2015 that is.

    The Future of 4K Gaming

    Where is 4K gaming going you wonder? Well, it’s definitely headed towards the mainstream of home entertainment. It’s already almost there with PC games and it will just be a bit longer before the same happens more formally with console games running with 4K TVs. Here is some available sample 4k videos  and here is where you can find movies in 4k .

    Just like HD gaming took off and became the gold standard of the gamers experience, the same will happen with its 4K counterpart, at least with offline gaming for the time being and later with online games as internet speeds more widely reach the kinds of 15 to 30Mbps speeds that they’d need to handle game streams at 3840 x 2160 pixels.

    Some Awesome 4K Games

    Finally, we move down to the meat of the matter with a mention of the kinds of 4K-ready games you can already play. Remember, any game that has been developed with 1080p HD playing in mind is already good to go for any 4K PC or laptop because it can be upscaled by your video card.

    But as for native 4K games, the following are some excellent choices to test out if you’ve got your own 4K PC and are rearing to go:

    Grand Theft Auto V

    Elder Scrolls V: Skyrim

    Call of Duty: Advanced Warfare

    Middle-Earth: Shadow of Mordor

    GPU Hierarchy - Comparison of Graphics Cards for Gaming

    Desktop GPU Performance Hierarchy Table

    Desktop GPU Performance Hierarchy Table

    By Chris Angelini December 15, 2015 12:00 AM

    Here is a resource to help you judge if a graphics card is a reasonable value: The gaming GPU hierarchy chart groups GPUs by performance.

    Best Graphics Cards for the Money is a hand-picked list of the top values, based on benchmark data, for your gaming machine. Most recently, we tweaked our approach to making recommendations, aiming them at resolutions and detail presets, rather than just pricing. The result was a significant shuffling. Don’t hesitate to let us know what you think of the change — or our choices — in the comments section.

    But when you want to know how your existing GPU fares against the one on your wish list, then consult our GPU hierarchy chart, which groups graphics cards with similar overall performance levels into tiers. The top tier contains the highest-performing cards available, and performance decreases as you go down from there.

    You can use this hierarchy to compare the pricing between two cards, to see which one is a better deal, and also to determine if an upgrade is worthwhile. I don’t recommend upgrading your graphics card unless the replacement card is at least three tiers higher. Otherwise, the upgrade is somewhat parallel, and you may not even notice a worthwhile difference.

    Сбалансированная система для игр: поиск узких мест по производительности GPU и CPU Общий анализ нагрузки и производительности

    Поскольку выбранные нами 20 игр дают совершенно разную картину нагрузки на CPU/GPU и зависимости от их производительности, то к подведению общих итогов следует подходить очень аккуратно. Вряд ли мы сможем вывести универсальные критерии, которые бы подошли всем играм.

    Возьмём в качестве примера игру Alien vs. Predator. Вы можете легко играть в неё со слабым CPU и мощной видеокартой. Но Grand Theft Auto 4 EFLC в подобной конфигурации будет серьёзно ограничена по частоте кадров, поскольку игра очень сильно зависит от производительности CPU. И если "бюджетные" комплектующие способны выдать больше 60 fps в старых играх без дополнительных расходов на апгрейд, то в игры класса DirectX 11, такие как Metro 2033 и S.T.A.L.K.E.R. вы вряд ли сможете играть без мощной видеокарты.

    По нашим диаграммам можно сделать некоторые выводы. Хотя одноядерный CPU нагружается всего на 88%, вы всё равно теряете около 30% потенциала производительности видеокарты. С двуядерным процессором незадействованный потенциал производительности видеокарты уменьшается до всего 9%, а четырёхъядерный CPU уменьшает его до 5%. Важно отметить, что многоядерный CPU может устранить рывки в играх, которые проявляются на системах с одноядерным CPU, когда игре требуется подгрузить новые ресурсы. В любом случае, все четыре ядра используются крайне редко, они оставляют для игр значительный потенциал по производительности.

    В данном обзоре мы сложили результаты частоты кадров во всех тестах без взвешивания. Все значения были представлены в кадрах в секунду. Мы решили не преобразовывать результаты в проценты, поскольку они всё равно указывают на преимущество двуядерных CPU, а сегодня покупают, по большей части, CPU с тремя или четырьмя ядрами. Как можно видеть, прирост производительности от разгона CPU несущественный при использовании максимальных графических настроек, разрешения 1920x1200 и видеокарты GeForce GTX 460.

    Энергопотребление

    На практике игра Supreme Commander 2 не может использовать все ядра CPU. Поэтому возникает интересный вопрос: сможем ли мы снизить энергопотребление, отключив ядра CPU через BIOS? На диаграмме ниже как раз приведено энергопотребление с разным количеством активных ядер. В среднем, вы можете сэкономить до 28 Вт, если уменьшите количество ядер Core i5 до одного. Конечно, мы не считаем данный сценарий реалистичным и оправдывающим себя, но для сравнительного анализа он весьма интересен.

    На второй диаграмме мы выключали ядра CPU в игре Anno 1404. Здесь интересно отметить разницу между двумя и четырьмя ядрами, поскольку при переходе на одно ядро частота кадров падает слишком сильно, и экономия энергии себя не оправдывает. Если вы не хотите играть со сниженной частотой кадров, то лучше использовать два ядра, что позволит сэкономить около 13 Вт от уровня энергопотребления системы в целом.

    Все измерения энергопотребления проводились от розетки. Блок питания Cooler Master RS-850-EMBA, который мы использовали, обеспечивает эффективность около 82%.

    Время загрузки игр

    Зачем переходить на мощный многоядерный CPU? Одна из причин заключается во времени загрузки. Разница может быть весьма существенной, и чем более сложная игра, тем более сильное влияние оказывает CPU. Чем короче полоска на диаграмме, тем быстрее загружается игра. Все значения указаны в секундах.

    Разгон CPU, наконец, оказал здесь существенное влияние. И если диаграммы наводят вас на мысли об использовании памяти, то следует помнить, что многие игры, такие как GTA 4, Oblivion и Fallout 3, используют практически полностью открытые окружения и миры, которые загружаются "на лету". Многоядерный CPU может значительно ускорить этот процесс, в результате чего игра будет ощущаться намного более плавной. В стратегиях реального времени, таких как StarCraft II и Supreme Commander 2, падение частоты кадров из-за загрузки новых эффектов тоже будет менее ощутимым.

    Минимальная частота кадров

    Всегда следует обращать внимание на минимальную частоту кадров. Действительно, зачем нужно новое дорогое "железо" с высокой средней частотой кадров, если иногда она просаживается до неприемлемого уровня? На диаграммах ниже показана наименьшая частота кадров, которую мы получили с учётом всех итераций наших тестов, которые не были полностью идентичными.

    Обратите внимание, что к оценке минимальной частоты кадров необходимо подходить очень осторожно. Учтите, что на диаграммах не приводится информации о длительности подобного проседания, о частоте возникновения или о причинах. Так что подобные измерения всё равно имеют весьма ограниченную пользу - лучше всего их использовать в качестве дополнения некоторых тестов в нашей статье.

    Заключение: переход на три ядра

    Кто бы мог подумать, но последние 3D-движки не отдают предпочтение процессорам Intel или AMD. Вместо этого мы видим совершенно иную картину. Когда большинство игр использовали DirectX 9, то вам требовался очень быстрый CPU, и они были не так широко распространены перед переходом на 65-нм техпроцесс из-за существенного тепловыделения. Переход на 65 нм, а также и на 45 нм позднее позволил производителям процессоров и оверклокерам поднять тактовые частоты, в результате чего разгон до 3,5 ГГц сегодня стал совершенно обычным делом.

    Однако новым играм под DirectX 10 и 11 вся эта скорость не так и нужна. Подобное изменение просто поразило нас, и разгон CPU для 3D-игр в случае использования комплектующих для массового рынка совершенно потерял своё значение. Из 20 протестированных в статье игр, только десять хоть как-то отреагировали на разгон CPU при использовании видеокарты GeForce GTX 460. Причём в семи играх мы получили незначительное увеличение частоты кадров, и только в трёх играх оно было чуть более ощутимым. Конечно, ситуация может оказаться совершенно иной в низких разрешениях, но мониторы с разрешением HD становятся стандартом среди геймеров, для них как раз будут актуальными видеокарты линейки Radeon HD 5800 или GeForce GTX 460, которую мы использовали в нашей статье.

    В следующей таблице мы свели результаты всех протестированных игр, так что вы можете проверить, готов ли ваш ПК к играм в нашей статье, или нужно выполнить апгрейд каких-либо комплектующих. Если вы планируете апгрейд, то мы покажем, что вам нужно обновить в первую очередь. Все протестированные игры обеспечивают более высокую частоту кадров с более производительными видеокартами. Оптимальное число ядер CPU, если судить по нашим тестам, составляет 2,75, так что мы наблюдаем явную тенденцию перехода на, как минимум, три вычислительных ядра. Эпоха двуядерных компьютеров, конечно, не закончилась, поскольку DirectX 11 вновь перенёс акцент на производительность видеокарт. Но, в любом случае, благодаря увеличению ассортимента и снижению цен, рынок всё равно движется в направлении четырёхъядерных CPU (или, по крайней мере, двуядерных чипов с поддержкой Hyper-Threading). Разгон центрального процессора оказывается практически бесполезным в играх с максимальной графической детализацией и разрешениями класса HD - если, конечно, вы не приобрели пару флагманских видеокарт, которые могут перенести "узкое место" обратно на центральный процессор.
