If you were to look at the $$ per TFLOP (which is somewhat arbitrary but I like it as a benchmark) then a $399 @ 10.3 console is not much different than $499 @ 12. ($38.83 vs. $41.66 per TFLOP). The other two versions don't fare as well. And of course this doesn't count things like amount of storage and the value of the ODD. There is no doubt that if the Series X comes in at the same price as the PS5, you for sure get the most for your money in the Series X. I'm not console warring - you get the more TFLOPS and more storage at the same price. When you compare Series X to PS5 digital with $100 difference - it still favors Series X. $/tflop is about the same, and you get more storage and the drive.
That's one way to look at it. The $/TFLOP is definitely a fun metric to think about.
XSS: $74.55 per TFLOP (299/4)
PS5D: $38.74 per TFLOP (399/10.3)
PS5: $48.45 per TFLOP (499/10.3)
XSX: $41.58 per TFLOP (499/12)
For most people I think a $399 PS5 digital would be the "sweet spot". I kind of see it like a GTX 900-series situation with the consoles mapping out to the GPUs like this:
XSS = GTX 960
PS5 = GTX 970
XSX = GTX 980
The 960 was decent when it came out, but aged very poorly, while the 970 was fast enough to play games at high settings for many years after its release. The 980
was faster, but since the 970 offered most of the 980's performance for a more reasonable price, it was considered the best choice out of the three.
To put it another way, spending $100 to go from the Series S to the PS5 Digital nets you 6.3 more TF, while spending another $100 after that only gets you 1.7 more.
