Why RX 5700 XT vs RX Vega 64 & not RX 590 vs RX Vega 64? My reason for this is because RX 590 is ROP limited with 32 ROPs while RX 5700 XT has the same 64 ROPs as the RX Vega 64.
RX 5700 XT is a newer architecture & benefit from that but at the same time I'm comparing it to the RX Vega 64 & not the RX Vega 56 . it's not a perfect way of comparing PS5 to Xbox SX but it should give a better idea of how everything isn't locked to TFLOPs .
And just so that no stones are left un turned I'll also mention that Xbox SX will have higher memory bandwidth than the RX Vega 64 & will also benefit from having a higher clock rate than the Vega 64 on top of being a newer architecture.
The paper below is from AMD comparing the RX 5700 XT to the RX Vega 64 & most of the things listed to show the advantage of RX 5700 XT are actually results of having a higher clock rate besides the higher Triangle cull rate & the added L1 cache
Now for the results in games
