Having already received a few glimpses into the performance of the new DirectX 12 technology from Microsoft in collaboration with AMD andNVIDIA, A new test shows us how extensive efficiencies and improvements can revolutionize gaming
Will DirectX 12 revolutionize the gaming market? In collaboration with Oxide Games and using the company's graphics engine, Star Swarm, Microsoft enabled the site Anandtech Seriously test the capabilities of the new technology for the first time. in short? Not only is the improvement between DirectX 11 to 12 in system performance is extremely significant, but also the efficiency of those systems will surprise you.
The test system of this experiment includes a 7 GHz Intel Core i4960-4.2X processor, 32 GB of DDR3 RAM at 1866 MHz, 750 GB of internal storage from Samsung's 840 EVO drive , ASRock Fatal1ty X79 Professional motherboard andWindows 10 in the Tech Preview version The second (9926) released last month. The graphics cards that participated in the test include the GTX 980, GTX 750 Ti, GTX 680, R9 290X, R9 285 and R7 260X with drivers in version 349.56 beta for a card of NVIDIA And drivers in version 15.200 for the AMD.

As soon as the test starts, with the basic test of the effect of the amount of CPU cores active on the system performance (using the GTX 980 card on the left and the R9 290X card on the right) it can be clearly seen that the technologyDirectX The 12 integrated in the Star Swarm game is several times more efficient than theDirectX 11 previous. As can be seen, the difference in performance between using six cores versus four cores is minimal and even negligible, which also shows that the interfaceDirectX 12 relies much less on the processor and much more on the graphics card in the system, a welcome optimization that will enhance the capabilities of most of the computers currently on the market. This optimization is also reflected in a better distribution of the load on several cores in parallel, in addition to more efficient processing of the information and thus also lower residence times. A more significant decrease can be seen when using only two system cores, which is the limit at which the efficiency of the technologyDirectX 12 is able to influence the results.
Side efficiency, a significant (and even dizzying) increase can be clearly seen here as well. If we look at the performance of the GTX 980 card we notice an improvement of more than twice as much as the DirectX 11 technology in any amount of active CPU cores, when the same (but in a much more extreme way) can be seen in the test with the R9 290X card. AMD's Radeon cards are known for low performance when using DirectX11 compared to the NVIDIA card in this test, but the use of the new version of the technology, in addition toThe Mantle Driver The company's astronomically increases system performance, with cases where there is a fivefold increase in system performance with the Mantle drivers compared to DirectX 11. Another very interesting point that emerges from all these performance tests is that the Mantle drivers of AMD Provide higher performance than the technologyDirectX 12 itself, showing the high efficiency and extensive optimization of the company with a card.
In terms of power consumption of the experimental system when using the various technologies we see slightly disappointing results. The Mantle Driver and the InterfaceDirectX 12 While providing improved performance in every performance test against the technologyDirectX 11, but the power consumption required for this is higher than the previous generation of the interface, with a significant change of almost 20 percent for the R9 290X card and about 22 percent for the GTX 980 card. In addition, the Mantle driver consumes the most power in this test , With an increase of more than 26 percent compared to the power consumption of the card with the technologyDirectX 11.

Even when comparing all the video cards of the test, you can immediately see the difference in performance between using the technology.DirectX 11 for the technologyDirectX 12 and Mantle. With the Extreme settings that load the system to the maximum, the GTX 980 card ranks first on the list (both in the dual-core test and in the quadruple test) with 26.7 frames per second when usingDirectX 11 compared to 66.8 frames per second with the technologyDirectX 12, 2.5-fold improvement (!!).
The R9 290X card sees a more than fivefold increase between DirectX12 and 11 technology, with even higher performance with the Mantle driver, a trend that continues throughout the experiment with the card of AMD. The same improvement is also seen when using only two CPU cores, but the amount of frames per second does decrease compared to using four CPU cores. Here too the advantage of the technologyDirectX 12 With low reliance on the processor and higher reliance on the graphics processor is expressed very well, this along with the dizzying increase in performance.

And if we isolate the performance of the Mantle driver compared to DirectX 12? Advantage of AMD In driver performance the Mantle is also expressed here, with an average increase of 5.6 percent in the amount of frames per second that the system is able to deliver. If we look at the same comparison but with only two active cores, it seems that although the Mantle drivers provide better optimization for the card of AMD In most situations, these drivers are not as efficient as the technologyDirectX 12 When it comes to the CPU bottleneck, which is reflected in lower frames per second on most cards.

To summarize the findings, we have brought you a graph that clearly shows the superiority of the technology.DirectX 12 and Mantle Mall DirectX 11. The graph, which shows "Frame Time" (the time it takes for each video card to produce and display a new frame), clearly shows us the reason for the low performance of the technology.DirectX 11 in front of its more modern competitors. Not only are the frame times of the old technology higher (and thus the amount of frames per second is lower), but they are also much less orderly and consistent compared to DirectX 12 and Mantle, which feature very low frame time and thus higher performance.
From all these tests, we understand that DirectX 12 technology is much more efficient than the previous generation of the interface, with lower processor reliance and better use of existing hardware in computers today. Until the launch of Windows 10, To bring with her The DirectX 12 technology for the masses, we will have to settle forImpressive performance tests That will make us drool over the potential of the future of gaming.
