First, Digital Foundry reports that the PS5 will make use of a 9.2 teraflop GPU, far more powerful than the PS4’s maximum of 1.84 teraflops. The next-gen PS5 will reportedly use GDDR6 memory, comparible to AMD’s RX 5700 series Navi cards. Finally, the PS5’s 36 custom Navi units will compute at 2000MHz, far greater than the PS4 Pro’s 36 GCN units which compute at 911MHz.
The PS5 GPU will also reporetedly switch between three modes — PS5, PS4 Pro and PS4 — as part of the console’s backwards compatibility offerings. Gen 2 mode is the PS5’s normal mode and will run PS5 titles, while Gen 1 (PS4 Pro) and Gen 0 (PS4) will emulate the running conditions of those specific consoles.
Information on the Xbox Series X is scarce, but Digital Foundry reports that the console’s GPU is “frankly ginormous”.
“There is no sign of clock-speeds in the data, but if we assume that 12 teraflops is the target, 1680MHz gives you 12TF on the nose, with a round 1700MHz delivering 12.2TF,” Digital Foundry offers.
