Absolutely worth a try, I haven't seen a detailed piece that compares to RTX yet, but I can at least address a few things based
strictly on what I've seen in the MS and Sony coverage this month:
GPU
Well, we know the RX 5700 XT has 40 CUs, but it's RDNA 1. So?? Not sure here. I haven't read about an RTX equivalent yet either. Pure TF is a trap as described in Cerny's talk. And the PS5 is definitely clocked higher than the XT. So...maybe somebody has a link to a piece with some comparisons?
If anything I think the concern here is that without RDNA2 or RTX 3000, if you buy a card now you kind of need the perf to be substantially better to comp for any gains or features that might be exclusive to next gen AMD/NVidia cards that haven't launched yet...
CPU
The XSX at first glance sounds like a 3800X, but cores are reserved and there's no boost clock. So the 3700X is probably the best comparison for both as it's 3.6GHz (4.4 Boost) 8 core. The reality is the 3600 is probably also equivalent because the 7th core is not going to make a tremendous difference. But to be safe, 3700X?
RAM
All consoles reserve RAM for the OS and stuff. Just buy 16GB. If you're on AMD that means go for DDR4 3200 and that's it. Actually, historically games use even MORE RAM on PC for whatever reason. VR, etc. So 16GB is a solid number but nothing wrong with 32...
NVME
XSX: I'm not
Dark1x but it sounds to me like QLC or TLC NVMe Gen3x4. The transfer rate seems lower than good TLC 3x4 drives (2.4GB/s vs say, addlink S70 which hits 3.4GB/s) , and if the expansion card is really that small maybe it is QLC? So all I'm saying here is any good 3x4 NVMe with DRAM cache is a good equivalent. I mean maybe it's TLC but with fewer NAND chips?
PS5: Phison E16 in all current Gen4 drives is both too hot and caps at 5GB/s (compared to 5.5 on PS5). So this means we have to wait for the Phison E18, E19, and Samsung 980 series, all of which are due in summer. They all promise better cooling, although PS5 may put market pressure on having thinner heatsinks. So tl;dr even the expensive AORUS 1TB is not fast enough. That's why Cerny said to wait.
The other thing worth nnoting is that Cerny said the PS5 drive is 12 channel. Even the Phison E18 is 8 channel so I would guess that although those products will exceed PS5 in transfer speed (I think I heard 6.5 or 7 was possible?) the extra channels will probably make it more or less equivalent.
Other
Well, if you want the full XSX experiennce you need to buy the NZXT H1 case. 😆
