Not really ?
PS4/Pro GPU : +128%
Pro/X GPU : +43%
This comparison alone said it all... GPU is by far the most decisive factor in a gaming hardware.
PS4/Pro CPU : +31%
Pro/X CPU : less than 1%
Concerning the bandwidth we have :
218/4,2 = 52Gb/s per TFlops
326/6 = 54Gb/s per TFlops
But this calculation might be too simplistic, i don't know.
Also, it's 33% more for the RAM. Pro = 8 GO GDDR5 + 1GO DDR3
I already mention it is true if u look only at % increases of TFLOPs . But bandwidth only increase by 25% from the 4 to the Pro while RAM amount allocated to games increases by .5 GB or 10% in terms of GDDR which is what that extra 1GB of DDR3 buys the PRO. Scorpio provides 64% more RAM to games than the PRO.
So 128% vs 43% alone paints one picture but when you look at 128%, 25% and 10% versus 43%, 50% and 64% (or 2.4 TFLOP, 42 GBps, 0.5 GB vs 1.8 TFLOPS, 108 GBps 3.5 GB) another is painted. If Tflops was the only important metric of a gpu than PC gamers would all be happy with 4 GB VRAM, 128 bit wide, 10 TFLOP cards.
