AMD’s DirectX 12 Featured Test for GPU

Ashes of Singularity Radeon GPU

Last week, Ashes of Singularity game was updated with the support for DirectX 12 Asynchronous computeAMD’s  Global technical marketing head “Robert Hallock” done some testing using Radeon GPU.

GPU Comparison

          Test bed system :

  •  Core i7-5960X
  • Gigabyte X99-UD4
  • 16GB DDR4-2666
  • Radeon™ Software 15.301.160205a
  • NVIDIA 361.75 WHQL
  • Windows® 10 x64

In the Given above chart, Radeon fury X GPU is the fastest DirectX 12 GPU. GCN architecture is enabling the DirectX 12 feature knows as Asynchronous shaders.

Data emerges from the Test

  • The Radeon R9 Fury X gets 12% faster at 4K with DirectX® 12 Asynchronous Compute. The GeForce 980 Ti gets 5.6% slower when attempting to use this powerful DirectX® 12 feature.
  • DirectX® 12 CPU overhead with the Radeon R9 Fury X GPU is an average of 13% lower than the GeForce 980 Ti.
  • The Radeon R9 Fury X GPU is a crushing 98% more efficient than the GeForce 980 Ti at offloading work from the CPU to alleviate CPU performance bottlenecks. At 1440p, for example, THG found that the Fury X spent just 1.6% of the time waiting on the processor, whereas the 980 Ti struggled 82.1% of the time.

  GPU Shaders

AMD’s asynchronous shaders  will not take each task in pipeline in sequentially. Some of the tasks in a pipeline will not work synchronously, but will take asynchronously either randomly.  This will help to generate more feature from the DirectX 12 ready Graphic cards using Asynchronous shaders.  These shaders are also important  as they have able to achieve high level of Graphics performance. Asynchronous shaders are the main reason for Gaming consoles have typically being able to achieve high frame rates than PC which is equipped with the similar level of GPU power and performance.

Here we see that the Radeon R9 Fury X is far and away the fastest DirectX® 12-ready GPU in this test. Moreover, we see such powerful DirectX® 12 performance from the GCN architecture that a $400 Radeon R9 390X Graphic processor ties it up with the $650 GeForce GTX 980 Ti.
