AMD may finally reverse NVIDIA under DirectX 12

In the graphic board market for PC,NVIDIAWhenAMDAlthough two strengths have been sharpening the pace for a long time, in recent years the deployment that NVIDIA overwhelmed with absolute performance or watt performance was normalized. However, Microsoft's new generation APIDirectX 12This power relationship has changed dramatically with the advent of AMD, and it is clear that the buds that AMD reversed NVIDIA were born.

Ars TechnicaIn order to compare gaming performance using DirectX 12, we measure various benchmarks using high-performance graphic boards boasted by both makers named NVIDIA's "GTX 980 Ti" and AMD "R9 290X". Main parts other than the graphic board are ASUS X99 Deluxe for motherboard, Intel Core i7-5930K for CPU (overclocking to 6 cores 4.5 GHz), 32 GB DDR 4 memory, SSD storage as Samsung SM 951, power supply as Corsair HX 1200 i It has become content that can fully demonstrate GPU performance.


Performance comparison is based on benchmark software "Ashes of the SingularityWith three different screen resolutions of 1080p, 1440p, 2160p,Multisample Anti-AliasingWith the performance (MSAA) turned off and the performance set to "hight", the DirectX 11 environment, DirectX 12 environment was executed on each graphic board.

First of all,frame rateMeasurement. The orange graph shows DirectX 11 environment, the blue graph shows the frame rate under DirectX 12 environment, and the larger the value, the better the performance. In the state where the CPU was fully used for 6 cores, the 980 Ti lowered the frame rate somewhat as follows, while the R 9 290 X succeeded in greatly improving the score. Even at any screen resolution, we are striking a figure which is thin at 980 Ti.


The trend that 980 Ti is sluggish and the R9 290X dramatically increases the frame rate is that the CPU core is limited to 4 coresHyper ThreadingIt remains unchanged even when it is turned off. Especially the R9 290X at 1080p resolution shows the dramatic effect of increasing the frame rate by 75% or more under the DirectX 12 environment, and R9 290X appeared 2 years ago than 980 Ti and the price is almost half price Given that it is a graphic board, it seems that it is staggering to demonstrate sufficient fighting power.


The average frame rate when CPU 6 core is used in intense drawing scene is like this.


Similarly the average frame rate of the CPU 4 core (without hyper threading) in a violent drawing scene is like this.


Lastly, in order to avoid variations in data, 99PercentileMeasurement result of frame rate at. Strength in the DirectX 12 environment of R9 290X remarkably stands out, finally realizing over 980 Ti in the end.


AMD · NVIDIA's performance comparison test of AMD / NVIDIA by Ars Technica of this time makes AMD which has been struggling hard so far, make you feel the possibility that under the environment of DirectX 12, the possibility to demonstrate the performance greatly exceeding NVIDIA graphic board It was the result.

This result is never a coincidence, AMD has been developing from the early development of its own API "Mantle"Graphics Core Next ArchitectureHas become a GPU design that matched DirectX 12's design philosophy that improved low-level control process that allows drawing commands and parameters to be passed to the driver on the memory buffer, which ultimately brings out great power That is why.


Thanks to the Mantle API, AMD, which has virtually two years 'lead' in development under the DirectX 12 environment, seems likely to reverse the performance difference with NVIDIA at a dash in the DirectX 12 generation .
