Vega 10大勝GTX 1080：當然是在OpenGL下 - 3C

http://www.ithome.com/html/digi/287719.htm

AMD在CES 2017上正式展示了旗下最新的Vega顯卡，現在工程版顯卡也通過Linus公佈到了
網上。 從包裹的黑色膠帶來看，Vega顯卡預計將會使用兩個輔助供電，而很大可能是公
版的8Pin+6Pin。

當然AMD首席架構師Raja對於Vega顯卡可謂是信心滿滿，認為和GTX 1080相比，全新的
Vega顯卡斯毫不遜色。 在接受PC world採訪時，Raja透露全新的Vega顯卡在運行4K解析
度《DOOM》的時候，最高幀數可以達到85幀，不過平均幀率也可以達到60-70幀，和GTX
1080相比領先幅度巨大，而且使用的API為老舊的OpenGL，還不是最新的Vulkan。

當然PC world的記者也詢問了Vega顯卡在DX11模式下跑分表現的時候，Raja表示《DOOM》
只有Vulkan和OpenGL，並沒有DX11模式。 Raja同時表示了Vega顯卡很快將會擁有ITX型號
，就是之前Radeon R9 Nano一樣。

The only demo you’ve let people play so far is DOOM running at 4K Ultra. I’
ve played it, it runs awesome it’s a great game. It can hit up to 85 FPS,
but typically it’s running 60-70 FPS at 4K Ultra everything cranked. Which
beats the pants off the GTX 1080, but that’s running Vulkan. Would it still
beat the pants of the HTX 1080 if it was running DX11?

DOOM doesn’t have a DX11 path…

Brad Chacos – Senior Editor,PC World
Yeah, OpenGL, you got me. (laughs)

I think it would. Because at that resolution things are more GPU bound, less
CPU bound. That’s one factor. But let me not say that too confidently
because the DOOM developer had done some console optimizations like line
assembly shaders and shader intrinsics and I don’t think they are available
in OpenGL. That’s not a fundamental OpenGL issue, it’s just that we didn’
t invest into putting all the extensions back into OpenGL which we could have
[done]. I only have a finite number of engineers so they’re just focused on
Vulkan.
