Tests showing that under RDNA 1 AMD hardware scales very badly under clock but very well to CU.
That's not true at all......5700XT is RDNA 1, PS5 is RDNA 2 (where all they did is worked on efficiencies and bumped the performance per watt to new levels on an enhanced 7nm node no less), otherwise PS5 would never hit such clocks, it only means the performance is there.....
Also, 5700XT is the highest end silicon on RDNA 1 at 251mm, it's perf is the ceiling so it makes sense that there is not a massive gain with clocks as AMD already had it pretty high by default....Still shooting to 2Ghz still gives you a nice 10% boost....
Yet your theory goes out the window, when the 5600XT was meant to compete with the 1660ti, but AMD boosted memory and clocks and it got a massive lead over that in firmware to actually outperform the RTX 2060 with little in increased wattage or heat......Expect even better performance per watt on RDNA 2, massive increases tbh...
Even with 5700XT, the only reason a 251mm GPU does not beat a massive sized GPU in the RTX 2080 is because you cant overclock the memory on the 5700XT too much......If you could hit 1200-1300 on the memory of the 5700XT, that would be another story.....
You guys are using all the wrong litmust tests, and not being truthful....It's just like people were looking at the price of SSD's early in this gen to determine
if we would get SSD's next gen....Or all the people saying 4K would be years away or 8K is 20 years away or 120fps (jah jah jah), yet it's all coming.....
RDNA1 is stupid fast for 251mm, RDNA 2 will support such clocks, much lower wattage and massive performance.....You can expect such clocks in your RTX 6900XT, 6800XT, 6700XT or much higher than what you see on PS5......and they won't run hooter than Nvidia.....They'd be on 7nm enhanced or 7nm+ EUV with massive efficiencies in the pipeline....
