Sony needs to do something about their memory bandwidth though. Thats the one area I see there being an issue for them down the road.
The PS5 has only 448GB/s of bandwidth shared between the CPU and GPU. 2ch DDR4 in PCs peak at around 50GB/s and 4ch peaks at around 60GB/s. So even if we say the PS5 is using 48GB/s exclusively for CPU related bandwidth and running the OS in the background, that's leaving only 400GB/s of bandwidth for the GPU. I just don't think that's enough.Especially considering that the XSX has 560GB/s of bandwidth exclusively for its GPU.
I believe its a money thing, cause from previous leaks its clear sony had tested their chip using faster RAM. So t just have been that the gains they would have got for their system going from14gbs chips to 16Gbs chips which would've landed them at 512GB/s of bandwidth probably wasn't worth the cost and going with 18Gbs chips which would have landed them at around 576Gb/s would have just been too costly.
