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 To seriously examine for the first time the capabilities of the new technology. in short? Not only is the improvement between 11 to 12 system performance is very significant, but also the efficiency of these systems will surprise you.

The test system for this experiment includes an Intel Core i7-4960X processor running on 4.2 GHz, 32 gigabytes of DDR3 RAM at 1866MHz, 750 gigabytes of internal storage from the Samsung 840 EVO , ASRock Motherboard Fatal1ty X79 Professional 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, GTX 680, R9 290X, R9 285 and R7 260X with drivers in the 349.56 Beta version And drivers in the 15.200 version of the .

As soon as the test begins, with the basic test of the effect of the amount of CPU cores on the system performance (using the GTX 980 card to the left and the R9 290X on the right) 12 integrated in the Star Swarm game is much more efficient than the interface Previous 11. As you can see, the difference in performance between using six-core versus quad-core is minimal and negligible, 12 relies a lot less on the processor and much more on the graphics card in the system, a blessed optimization that will enhance the capabilities of most of the computers currently on the market. This efficiency is also reflected in better distribution of load on several cores at the same time, in addition to more efficient processing of information and thus also lower latency. A more significant decrease can be seen when using only two system cores, which is the limit at which the efficiency of the C- 12 can affect the results.

Side efficiency, a significant (and even dizzying) increase can be seen clearly here as well. If we look at the performance of the GTX 980, we will notice more than twice the efficiency of the DirectX 11 technology in any number of active CPU cores, while the same thing (but much more extreme) can be seen in the test with the R9 290X. AMD Radeon cards are known to perform poorly when using DirectX11 compared to the NVIDIA tab in this test, but the use of the new version of the technology, in addition toMantle drivers Of the company astronomically raises the performance of the system, with cases showing a fivefold increase between system performance with Mantle drivers compared to DirectX 11. Another interesting point that comes out of all these performance tests is that the Mantle chipset Provide higher performance than 12 itself, which shows the high efficiency and extensive optimization of the company with a tab.

In terms of power consumption of the experimental system when using different technologies seems to be slightly disappointing results. The Mantle driver and the Although the 12 delivers improved performance on any performance test against X- 11, but the power required to do so is higher than the previous generation of the interface, with a significant change of almost 20 to the R9 290X and 22 to the GTX 980. In addition, the Mantle driver consumes the most power in this test, with more than 26 more than the power consumption of the card with the M- 11.

Even in comparison between all the video cards of the test can immediately see the difference in performance between the use of technology - 11 technology 12 and Mantle. With the Extreme settings that fully load the system, the GTX 980 card is placed first on the list (both on two-core and four-test) with 26.7 frames per second when using the 11 vs. 66.8 frames per second with X- 12, improved by 2.5 (!!).

The R9 290X card sees more than five times the increase between DirectX12 technology and 11, with even higher performance with the Mantle driver, a trend that continues throughout the experiment with a card . The same improvement is seen when using only two CPU cores, but the number of frames per second does decrease compared to the use of four CPU cores. Here, too, With low processor reliability and higher reliance on the graphics processor, 12 is performing very well, along with the dramatic increase in performance.

And if we isolate the performance of the Mantle driver against DirectX 12? The advantage of The performance of the Mantle drivers is also reflected here, with an average increase of 5.6 in the number of frames per second the system is capable of delivering. If we look at the same comparison but with only two active cores, it seems that the Mantle drivers provide better optimization for the In most situations, these drivers are not as effective as the 12 for the CPU bottleneck, which is expressed in lower frames per second on most cards.

To summarize the findings, we presented you with a graph that clearly shows the superiority of the 12 and Mantle-front 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 poor performance of the 11 against its more modern competitors. Not only are the frame rates of the old technology higher (and thus the number of frames per second is lower), but they are also much less orderly and consistent compared to 12 and Mantle, which display very low Frame Time thus Higher.

Of all these tests, we understand that DirectX 12 technology is much more efficient than the previous generation of the interface, with a lower reliance on the processor and better use of existing hardware on today's computers. Until the launch of Windows 10, To bring with her The DirectX 12 technology for the masses, we'll settle for theImpressive performance tests Which will make us drool about the future potential of gaming.
