I think gains in I/O will be more noticeable than gains in their CPUs. SSDs are being choked and held back by PCIe 3.0 interfaces at this point. I'm not sure that PCIe 4.0 is any better on latency. It would be interesting if Apple took a big leap forward with a low latency interface like OpenCAPI, or maybe some iteration of RapidIO. Something like Optane over OpenCAPI would be a huge leap in speed. Optane is wasted right now with PCIe.

The PS5 apparently has incredible disk I/O, possible due to RAD's compression technology. A super fast compression codec could make a difference too.
