52CU's - 100%
36Cu's - X%
X% = 100 - ((36CU's * 100%) / 52CU's) = 30.7% where's 50% from?
also RT works in parallel not allocating individual CU's.
also PS5 RT solution is more elegant then RDNA 2.0 not sure what that means but it's likely customized.
also RT can be calculated along with other ops except textures ops because it's shared 4 ops/clock.
ps5 36 CUs are 100%
xbox 52 CUs are n%
so xbox has n= 52*100 /36= 144,5% the cu's ps5 has. (somehow when I did the calculation in my mind before, I used 54cus instead of 52, hence the 150% instead of 144%)
as for the "elegant solutions" mystique and etc cerny sweet talk, yeah, ok.
both consoles are customized. why should sony's
undescribed solution be more "elegant" than microsoft's? if anything, from what both companies have shown until now it seems that more "elegant" is the microsoft approach. (form factor, thermal footprint, Hz, power levels etc)
the "allocation" was to make the example easier to understand. would you prefer to break it down to cycles of individual CU's?
The problem is that you are suggesting something that is not real...
Xbox can use 36 CU for rendering and the rest for RT, PS5 can't do that because it just has 36 CU... Yea, but PS5 has more clock speed per CU, meaning Xbox will be at a disadvantage if something like that happens...
The reality is PS5 can use 8 CU for RT for example, and XSX can use 12, but RT will be calculated faster per CU in the PS5, making the difference one more time 18% percent...
The calculation that has been used to show this 18% already includes the difference in CU count between both systems, whatever ends up been the real number of CU used for RT, the number will decrease proportionally between both consoles, and the difference in performance will stay the same.
no, I wrote that for the same 28 CUs that PS5 allocates to rendering/shading/etc, xbox allocates 36, thus already over-compensating for the Mhz difference when ps5 runs at full speed.
then, while ps5 will have 8 CUs, xbox will still have 52-36= 16 and not 12, twice as many just like I wrote above.
on top, if you want to get more complicated, I'd ask that -since this sounds like a "worst case game" scenario per cerny's vocabulary- what would the real ps5 clockspeeds be at that case?
anyway....
soonish there will be no more "elegant mysteries", that's one thing that is for sure.
