When games are design in traditional way (no data streaming like UE 5 or future rendering technique) games will run slightly better on Xbox SX (probably slightly better resolution or frame rates).
But if games are design with new philosophy and next gen rendering tech where data streaming on real time is crucial (frame by frame) like UE 5 , then games will run worst in Xbox SX or slower and will have pop up in LOD, or worst it will not run at all.
Developer need to modified the engine to run on Xbox SX so GPU do more GPU calculation instead depend on real time data streaming like PS5.
In the end both are great machine which has plus and minus, one have advantage than the other in one aspect and vice versa, So now it depent on how developer harness the technical side of thing from both.

Bit of a stretch to assume the Xbox Series X isn't as proficient in streaming assets from SSD, there could be additional details on this front that hasn'e been elaborated upon, Microsoft, like Sony have invested allot in the technology that backs up the SSD... Which is actually the most important aspects rather than the "raw" GB/s in the spec sheets.

UE 5 is the prove of this, but you are right, no games use this tech yet. We will have to wait and see. But on paper and developer notes next gen PC games and multiplat will require more RAM to overcome this problem or an SSD. Or a very powerful GPU and CPU to brute force the lack of IO speed.
Of course next gen games will be available 2 to 3 years after next gen console released, from now on only 1rts party developer will use that benefit especially SOny first party (Xbox will focus on cross gen for another 2 years).

More CPU/GPU doesn't make up for slower I/O, unless you are doing something like procedural generation that relies heavily on CPU/GPU generation algorithms or some such.
The Xbox Series X unlike the PC however... Has the same amount of Ram as the Playstation 5, so it will need to rely on streaming assets into memory where-as the PC can dump more data into memory to start with and be less reliant on storage speeds. - That's the main difference between PC and consoles next gen.
I think I speak for everyone though when we can finally get rid of load times and get back to the "instant play" that we had back in the Nintendo 64 era.

I think the lack of knowledge on game development and on lack of info on how this new paradigm will affecting game development, resulting on many people doubt SSD/IO will change a lot of thing. Even many PS fans (i also had my doubt back in 2019 ) still not understand the important of IO and SSD. Hell most of them are PC, PS fans, Xbox fans , and Nintendo fans who don't have time to do some research will still think " Teraflop " is still the most important factor.
Glad i am doing my own research and glad a lot of Youtube videos explained this.

The Switch, WiiU, Wii, 3DS and so forth had solid state storage. It might only be cheap shit emmc or in a carts case... ROM, but it was still solid state.
I/O is important, it's always been important, mechanical hard drives and consoles stagnated for a couple of generations... And the PC only increased marginally on this front over time.
If storage increased at the same rate as Ram bandwidth since the Nintendo 64 we would be running with SSD's that offered 280GB/s... Which is nuts. That would mean storage would offer sufficient memory bandwidth to handle 1440P resolutions. (Latency and other factors not withstanding of course.)
In saying that, storage isn't a replacement for super fast Ram, it helps, but systems have a tier of memories ranging from smallest, lowest latency, highest bandwidth with L1/L0 caches to largest and slowest hard drives/ssd.

Yeah agree about PC will rely on dumping everything in to the main system Ram
Xbox can do assets streaming in but compared to PS5 it just not on the same level, so if Xbox trying to run the games like PS5 expect there will be some pop in in LOD or frame rates down or some lag. Unless the game engine is procedural generation that relies heavily on CPU/GPU generation algorithms or physic , or relied a lot on path tracing. Some water/cloth/ hair and particle simulation and deformation on character also relied on compute unit.
Before we have new info about Xbox SX IO costume , i will stay on my opinion that PS5 for now is still mile a head in terms of IO, also PS5 SSD raw speed also bigger than Xbox SX speed.
SSD wont replace RAM it's true , the problem is that traditional game design always relied on a lot on RAM to mitigate the lack of storage bandwidth due to dependency on HDD/ CD/DVD /Blue RAy.
Even games that made on cartridge like Switch are made with mechanical drive in mind. With this philosophy RAM becoming the big factor, every game need to be loaded first on RAM. With fast SSD and fast IO it change everything . it will not the same again because game doesn't need to be loaded and it just transfer and stream the data you need for a few minutes ahead.
So yeah, we finaly returning to N64 era.
