That is very likely the result of a doubling of FP32 units like Ampere.

This should result in a significant drop in the 'Teraflop per watt' performance vs. RDNA2, much like the RTX 3080 might have 2.8 times as many Teraflops but perform 1.6 times better on average (only ~57% of total scaling).

Edit - but even without the doubling that'd be 46 Teraflops for ~ 600 W, so yeah. The thing's massive.

According to Greymon55, Navi 31 will be around 450 to 500W. Subject to change ofc :P

That tweet is from last year, when the chip was supposed to give 75 TFlops, but if it now performs better, it wouldn't be strange if it also uses more power.
