The SSD in XSX is plenty fast enough to prevent pop-in. It's throughput is something like 40x faster than the 5400 RPM hard drives in XB1 and PS4. The faster SSD in PS5 will mainly show itself in load times I think, but even then I think it'll be a fairly small improvement. |
You still haven't figured out what the Cerny talk was about, apparently. Hint: It has pretty much nothing to do with load times.
As far as this UE5 demo goes, we have no idea how much data is streamed, averaged per second, or what the peak rates are. I somehow doubt it's in the GB/s as that would end in games that are TBs in size...
We know that in the PS5 architecture, the whole streaming is in hardware and apparently has a theoretical ceiling of 20GB/s as per Cerny, and averages <=8.5GB/s after decompression. All we know from the XSX is that it has a transfer rate that bests around 4.8GB/s after decompression for texture files (and lower GB/s for other stuff). We have no idea what happens afterwards with that <=4.8GB/s but we know the data is in gpu memory space at least. We know that PCs currently are heavily disadvantaged because the decompressed (by one or more cpu cores) data is in cpu memory space.
As UE5 won't be available until 2021 (probably with a somewhat steep learning curve attached to it), it'll be a long wait for the first spectacular games in UE5 to show up on consoles.
