12 teraflop confirmed, LOL. in GCN number Navi teraflop are equal to 1,4 times of GCN performance 12X 1.4 = 16.8 teraflop of GCN from Xbox One = 16.8/1.3= 12.9 times more powerful than Xbox One.
Flops is not everything when it comes final look of games, but it's there to measure theoretically . So it's a humongous improvement.
So we still need to confirmed PS5 performance before we close this nthread.
