Their is something very off about this statement, as this fellow put it:
I think what Heisenberg is trying to say is that Sony may custom-optimize a few very specific things in particular, not necessarily that MS is gonna hulk-smash their way to a solution. Because honestly, that would run contrarian to the optimization they've done for XBO and the X.
Both of them are going to have some very smart and critical hardware/software optimizations; you'll probably just seen one
really specific area or two where they differ.
I don't belive in Series X SSD 7 gb/s rumor, we have no insider/dev telling about Series X SSD. but we know Sony's SSD is ultra fast, uses proprietary technology and have been patented.
In SSD, I am confident in PS5 superiority / large superiority.
Phill Spencer talks in 40x faster and MS doesn't comment so much in that
Based on what? I mean think about it; Zen 2 processors support up to 24 PCIe 4.0 lanes. Why would MS limit a NAND memory controller interface to just 1x PCIe 4.0 lane? Even if these systems cut down on PCIe lane interface totals, they are still leaving a lot on the table.
The 40x comment was probably never meant to be taken literally, it was just a general estimate and maybe based on a slower-speced SSD they were using for testing at the time. I expect both systems to have between 7-8 GB/s NVMe SSD support over 4x PCIe 4.0 lanes.
At least that is for the custom drive; assuming the systems will have a custom drive as a memory-mapped cache and allow for external drives, it's possible the 2 GB/s number was in reference to the optional 2nd drive, not the custom one (which will probably be non-removable, for both systems). I guess in that case 2 GB/s could be an issue down the line for that secondary drive, but since it would basically be for cold storage, it would not be a big bottleneck whatsoever. In fact, for cold storage you likely wouldn't be using too much anyway, 2 GB/s is pretty hot.
