If your hardware takes five years to be fully utilized, you didn't design a forward looking piece of hardware, you designed a dud.
Oh look, our OpenGL drivers was so rubbish that if we move all the work on the developers shoulders this game gets 50% faster! Wow! What an achievement :)

I thought Sontin was being sarcastic after people went crazy accusing id & NVIDIA of sabotaging the new doom game on some AMD parts. I can't otherwise make rational sense of what he wrote :)
If you understand what preemption is then you know it makes no sense to say it's used to run concurrent tasks.
Let me tell you how concurrent tasks run on Pascal. It's really easy. You see, some SMs are idle and the HW scheduler decides to schedule some independent compute (or graphics) work on...
It's not even propaganda. He doesn't really know what he's talking about. Perhaps he thinks modern games spend half of the frame time blitting stuff around.
I was talking about the new Polaris primitive discard unit, not primitive discarding in general. As I mentioned earlier in this thread conservative rasterization is the corner stone of countless rendering algorithms, which is why it's such an important feature.
You are not reading slides correctly. A GCN instruction runs for 4 cycles, on each cycle p 16 vector lanes are processed, for a total of 64 lanes. This is the smallest unit of computation on GCN and it's called a wavefront. Wavelets are completely different objects :)
An NVIDIA SM smallest...
It's not the same. GCN logical SIMD width is 64 vector lanes, not 16. NVIDIA SIMD width is 32 vector lanes, which makes it less likely than GCN to suffer from so-called SIMD divergence issues. On the other hand it's highly unlikely this is what makes NVIDIA HW vastly more efficient than GCN. The...
Oh boy, ignorance is bliss. Those DX11 titles use NVApi to provide support for features not supported on DX11. The very same features that are officially supported in DX12. 5 seconds on Google is all you need to confirm those are DX12 features, but please, keep trolling.
Intel supports both...
Those features are NOT available on DX11, they were introduced in DX12 and GCN does not support them.
Conservative rasterization is a cornerstone of computer graphics and it's used in hundreds of algorithms. Saying that it's useless because it is used in some algorithm you don't like because...
Also AMD still doesn't support very important DX12 features like conservative rasterization and raster order views. Unfortunately even Polaris doesn't support them.
