> The SPU approach is pretty much what a GPU does, but instead of 64 they have hundreds if not thousands.

Eh, only if you count every SIMD lane as a separate "core" like GPU manufacturer marketing does. More realistically, you should count what NVIDIA calls SMs, where the numbers are more comparable (GeForce RTX 3080 has 80, for example).



PS3 6 SPUs(1 is system reserved) 4-way SIMD

PS4 - 18 GCN CUs, each has four 16-ways SIMDs for 72 SIMDs but each is 4 times wider so PS4 has the same number of ways as in 288 4-ways SPUs.
