This is the low-end/cheapest card in AMD's stable ATM or will end up being soon enough and certainly by the time PS5 launches.
It probably gives us an idea of what we can expect in terms of performance, Polaris will be phased out and Navi is unknown ATM.
https://videocardz.com/amd/radeon-500/radeon-rx-vega-xl this card should be around 114w+- once they switch to 7nm (RX480 TDP is 150w).
It's the 56CU (the other two have 64CU's) version running at 1600Mhz, using GloFo press release on 7nm vs 14nm gains this card would be 16TF (in theory).
Basically there won't be any other card beside Vega and Navi for Sony to choose from so it's going to be one of them, older parts are cheaper.
AMD could throw in some refinements they've made on Navi and deliver a compelling price/performance for the platform holders without breaking the bank.
Just doing a raw math if that's how it works,
>40% performance gain over 14nm, even downclocked and running at 1300MHz with 56CU you'd end up at 13TF.
I don't know about you guys but downclocking a GPU by 300MHz is really a lot, 13TF would be the minimum in that case if it's clocked higher than 1300MHz.
Navi should be more efficient (7nm EUV) but we don't know jack shit what that GPU will be, at least the prospect of a 10-12TF GPU is looking good.
