nothing else does, though... real world applications show an average performance of 90% for the fraction of the price.
In fact, that Tom's review linked above even goes as far as to state that SpecView shouldn't even be considered as valid because it's outdated and both camps inflate their numbers artificially in some benches and that doesn't reflect reality. In the tests done there, Vega competes very well, in fact beating the P6000 in some tests while also being 1/5th the price.
As for what
@Glo. is talking about Raja talked briefly about it in his AMA on Reddit and his answer very much read like "when coded for specifically in Vulkan or DX12 Vega will shine" so it is still possible that there is a lot to tap into, the real question is who is actually going to bother?
If there was a patch coming for AAA titles then there would be announcements just like the Ashes Ryzen patch. DICE and Bethesda have said 0 about getting a special Vega optimized patch released for any games, which either means that one isn't coming, or that it's not coming any time soon. So the question is, if AMD's biggest game developer friends aren't going to push a Vega patch out, who is going to actually bother to write Vega specific codepaths for Primitive Shaders?
@Glo. I appreciate your enthusiasm for the underlying workings of GPU's , but we all do need to accept that while AMD has been technically superior in some ways before, it doesn't often translate into increased performance in mainstream products. Primitive Shaders very well may actually have a 40% performance increase in geometry bound scenarios, but with a 20% market share and not enough engineers to send to help game developers write this code it's also entirely possible we may never see a true implementation of Primitive Shaders. This is why people are fighting with you, because a lot of them are sick of AMD having great technology that doesn't translate into performance that matters to them. I personally have no problem with your optimism in regards to AMD's uarch prowess, I just think when you're the little guy and you have to ask for people to help you out, it usually doesn't work out well for you.
