Indeed it is the I/O Coprocessors and DMAC in the PS5 I/O complex that should have the biggest impact on reaching 100X improvement. The decompression is for increasing throughput. That alone wouldn't eliminate bottlenecks when executing file I/O code. On the other hand the XSX should have similar hardware once we get to see what's really inside.who told you it was those two things that had the biggest impact on the I/O rather than the other improvements such as the on chip decompression which has already been said to have the biggest impact?
