Just wanted to second this, and add my own thoughts.
IIRC, in his Control comparison for the RT update on PS5 and XSX, he stated that the loading stutters on XSX were because it lacked PS5 IO. Clearly this was absolute nonsense, and Remedy duly patched the XSX hardware to have the PS5 IO hardware block.
Just a few days ago he retweeted the new hi-res PS5 die shots, and said that it might have Zen 3 unified cache and that he would "do some digging", again IIRC (and I think I do). That's with super awesome high res images of two entirely separate quad core CCXs with their own (Zen 2 style) L3 caches.
His comparison videos are good, and I'm certainly not suggesting he doesn't add a lot to the conversation and take pride in his work, but when he tells you why the hardware is responsible for the performance you're seeing, take it with a pinch of salt. He really needs to back off from attributing what's quite possibly software related to "it's console (x) sauce" or "platform deficiency
".
I think he'd benefit from a newer CPU with better single thread performance. Zen 1 / Zen+ was a little weak in thread in single thread (though a big advance over loldozer) and it didn't clock very high. Plus CPU and mobo drivers probably didn't get the support of Intel and later AMD devices due to the relatively low user base. Zen 1 and Nvidia is possibly not the greatest combination. He might not be able to afford it though, so I'm not going to be too critical - I'm broke as hell and still rocking a 4790K!
More NXG comparisons, absolutely, but ease off on the certainty with "why" a bit...
