又係典型連登討論可以幾十個回覆一個concrete spec 同source 都冇俾
PS5 RDNA2 32 Compute Units (CUs) @ 2.23GHz w/ 16GB GDDR6, raw performance 10.3 teraFLOPS
Xbox One Series X 52CUs @ 1.825 GHz w/ 16GB GDDR6, raw performance 12 teraFLOPS
Tesla Model S Plaid RDNA2, raw performance ~10teraFlops
Radeon 6800 RDNA2 60 CUs @2.1GHz w/ 16GB GDDR6, 16 teraFLOPS
desktop equivalent:
Radeon 5700XT RDNA1 40CUs @ 1.9GHz w/ 8GB GDDR5, raw performance 9.754 teraFLOPS
PS5 VRAM 更多更快而且用RDNA2, 有UMA (即包埋同勝過AMD Smart Memory Access) 就算唔計console optimization 可以更有效率都spec 都勁過desktop Radeon 5700XT
而spec 上限目前咪係Radeon 6800
再睇返5700XT 同6800 之間可以有幾多張discrete graphics card 咪估算到個raw performance 囉 (呢度唔考慮console sw hw optimization, 淨係考究個GPU 底子)
