No, otherwise NVidia would get crushed by AMD already. It does tell the theoretical peak performance, but that's rarely achieved in Gaming, and far from it on AMDs current chips.

However, a console with 13-15TFlops in GCN performance was out of question from the get-go unless Navi would have become less consuming than Turing. And while Navi certainly bettered itself in that regard, it's still les powerful per watt then NVidias offerings.

For the record, I calculated the theoretical TFlops for the 5700 and the 5700XT and reached pretty exactly 7.5 TFlops and 9 TFlops respectively in gaming speed, so I'm sure they choose those clock speeds exactly for that reason. And considering the power consumption of either card, I think the 5700 (non-XT) is pretty much what will fuel the next gen consoles in one way or another.

Likely a cut down version.

I expect that the GPU in the next gen has 36-44CU (if we can still talk about CU with RDNA), but at a lower clock speed than retail graphics cards. And integrated as the GPU part of an APU.

If it's not going to be an APU design, then I don't expect AMD to change the chip at all, it's gonna work with GDDR6 either way, if it got it all for itself or has to share it with the CPU. They probably just lower the clock speeds a bit to ensure stable, predictable performance.

RTG continues to need a full node advantage to hope to match Nvidia after Maxwell in efficiency. But now they are lagging even further behind than Polaris etc. with the competition's ray-tracing cores. Catastrophic.

Not totally sure about that.

I do think they still lag behind, but much less than you'd think at first. After all, the 225W of the 5700XT is not the TDP, but total board power, meaning it includes everything on the board, like the VRAMs for instance. It's quite possible the TDP of the chip alone is closer to 180W, and thus in the ballpark of the RTX 2070 (175W TDP). But we'll have to wait and see for power consumption benchmarks to have a clear picture here.

About Raytracing, considering that you'd prefer playing without raytracing right now if you want the best graphics and good framerates since it's simply too demanding even for a 2080Ti, I don't mourn it's absence. It does have the option to do Raytracing in it's Shaders though, but it's just not worth it yet, not on Radeon or an RTX.

On the other hand, Navi has an auto-sharpener to make the picture even crispier at almost no power cost (AMD states 1%), which is better than anything DLSS can do in theory (and everything is better than DLSS in practice; seriously DLSS should stand for Doesn't Look Smooth and Sharp)
