So assuming it's using the same custom RDNA2 GPU (I checked, seems it does), this is going to be slower than the Series X by quite a bit considering the Series X is [email protected]. That's not sounding good.
It's not even in the same galaxy as the Xbox Series X. The PS5 is a 2019 console that was delayed, and overboosted in the last few weeks to break the double digit TF range. It's spec was 9.x TF from the start.
Let's not forget about the ray tracing processors on the Series X as well (another 13 TF of shading performance).
Sony's SSD is good, I'll give them that but it's super proprietary which is going to be expensive at the beginning.
