What's so funny about that post? It's true. Series X has higher compute FLOPs but other parts of the GPU are faster on PS5.
Series X and PS5 - both have 64 render output units.
It's 64 ROPs * 1825 = 116.8
"116 Gpix/sec" as confirmed by MS themselves
Do the same calc for PS5 - you get
142.7 Gpix/sec - 22% uplift in pixel fillrate over XSX due to faster ROPs!
Bonus:
The one next to pixel fillrate is the rasterization rate (7.3 Gtri/sec). There are 4 primitive units on the SX. So, 4 * 1825 =
7.3
AFAIK, AMD seems to be using 4 primitive units from GCN 2 (290/290X) to GCN 4 (Polaris) up until RDNA 2. So PS5 must also be using the same amount of primitive units. On PS5, this would be 8.92 Gtri/sec - again, a 22% uplift. Apart from this, the caches in PS5's GPU should be 20%+ faster too.
TL;DR:
XBOX Series X: 12 TFLOPS, 560 GB/sec, 7.3 Gtri/sec, 116 Gpix/sec
PlayStation 5: 10.3 TFLOPS, 448 GB/sec, 8.92 Gtri/sec, 142.7 Gpix/sec
