The TFlops you're quoting are at peak boost performance, which the GPU can't hold without consuming much more than those values you're posting below. For instance, in the Techpowerup test the GPU only reached 1672 Mhz on average, which results into almost exactly 7.7 TFlops. Undervolting will simply not be enough to get to 10 TFlops, especially since 160W is already the maximum a console can take. And Navi translates that into more clock speed anyway by itself unless you lock the speed - but that only gives like 30-40 Mhz in general while it would need more like 200-300 Mhz to make it work for your example.

However, I agree that I did mess up a bit, I took consumption at max boost and used the TFlops at base clock. Still, my point stands that 10 TFlops are still out of reach

Maybe you were correct after all, but you might be missing a few things, we know Amd Zen3 and Rdna2 will use 7nm+. What does 7nm+ actually mean though? This is a term Amd uses and not TSMC, everyone assumes it means 7nm EUV including me a few days ago. The terms Tsmc uses are:

N7, N7+ and N7P

N7 + Navi/RDNA1 = 1.7Ghz

N7P + RDNA2 =

PS5 retail will have 40CU's but 4 will be disable, 36CU's + 2ghz = 9.2TF

Xbox Series X will have 56CU's but 8 disable, 48CU's + 2ghz = 12TF

Everyone seems to think PS5 will be above 10TF and maybe even beat Xbox Series X, they will be in for a chock. This is my guess.

I know that everyone is caught up in this FLOPs talk, but what about Ray Tracing Cores?

Lets say in theory, Micrsoft and Sony both set out to make a 400mm2 APU. Now it is all about finding a balance between CPU Cores, GPU Cores, Ray Tracing Cores, Cache, Memory Controllers, and such. We can theorize that GPU Cores should be equal in size with both using RDNA and likely the same fab. So if Sony is dropping 40CU's on its chip and Microsoft is dropping 56CU's on their chip, then that means that Sony potentially has a sizable amount of chip left for something else. If we again consider RT Cores to be equal, then it could be possible for the PS5 to have say 36RT Cores while XSX has 20RT Cores. 

We are entering a new era with new technologies. I think we have to consider much more when thinking about these chips than just traditinal cores and clock speeds. One chip could be incredibly capable in traditional rendering, but suffer in RT rednering, while another could be less capable in tradtional rendering, but be incredibly capable in RT rendering. At the end it could mean that the chip with weaker traditional silicone and stronger RT silicone ends up supirior in overall next gen graphics capabilities. Or, the two strenghths and weaknesses could balance them out. Or, the chip with more traditional cores, could just end up better.

There are just too many factors to focus so much on FLOPs and CU's.
