35W seems very close. Does that mean the 4080 won't be as fast as we think or that the 4070 will be faster than expected?
Could be neither. AD104 vs AD103 looks to be quite different so a highly strung AD104 vs a more chill AD103 can give a large performance delta at similar power levels. Think 6700XT vs 6800 where both use a similar amount of power but at 4K the 6800 is 24% faster.
