엔당의 dx12는 AMD보다 더 뛰어납니다.

이건 어디까지나 Maxwell 2.0(9xx, Titan X, ..)에만 해당되는 얘기입니다.

암드가 엔비댜보다 dx12에서 좋다는건 Maxwell 1.0까지의 얘기입니다.

심지어 기능 지원폭도 Maxwell 2.0이 GCN1.2에 비해 더 넓습니다.

아래 표를 보시면 얼마나 치밀하게 엔당이 멘틀에서 dx12로 전환될때 준비를 했는지 아실 수 있습니다.

So here is the thing. Maxwell 2.0 (GM200) has the hardware characteristics necessary to get the 12_1 stamp, so it does. However, AMD’s GCN actually has Resource Binding Tier 3 for a very long time now, not to mention Typed UAV Format Tier 2 and Asynchronous shaders for parallel functions. Similarly, Intel has supported Raster Order Views since Haswell iGPUs and has been rocking it on Feature Level 11_1. To put this into perspective Nvidia’s architectures supports ROV only after the GM200 Maxwell. You can clearly see that no hardware vendor has the undisputed best GPU hardware specification around.
