Storage Showdown - Intel Alder Lake vs. AMD Zen 4 | TweakTown

AMD needs to fix whatever is causing the slowdown. Otherwise, they will be at a disadvantage when the gaming world moves to DirectStorage.
IMO your conclusion is premature because the benchmarks don't correlate; you've got AMD winning some by like a gigabyte per second and others with Intel doing the same in return, and many won by a nose / close enough to be considered within a margin of error based on background system activity. At this point I'd assume that at least some of these benchmarks benefit a particular architecture, maybe because of the compiler that was used.
If there was a correlation between all these benchmarks, the next thing I'd do is to test both hardware platforms on Linux, and if there's a similar correlation there too, then maybe you can start talking about the hardware. Even then, I'd do additional tests on Windows, say testing Samsung SSDs with Samsung's NVMe driver and look for a similar correlation (I don't know if other SSD makers also have their own favoured drivers), because it could be an issue with the Windows NVMe driver, for example. I'd also test Win10.
I haven't checked the figures for this, but the only correlation I saw in them was that the SSD models seem to come out in the same order (when comparing the Intel figures to the AMD figures), which is a
start, I guess.
Furthermore, in my experience it's typical for the ATTO benchmark to absolutely hammer the CPU at the low end of the transfer spectrum (e.g. 512B/sec). I've seen a fair bit of variation on different machines for the same SSDs over the years.
