Again. Re read original question and stop taking this so emotionally.So you think a bunch of unknown quantities that you confirms it's XSX lol.
There is only one link, and thats the Render back ends in BC mode. The rest is your assumtion, which could well be as wrong as your assumption about ps5 considering it's old data.
We don't know how many CUs, ROPs, or bus width the retail series X is going to come with. Also VRS and RT prove nothing either both console will have these.
Github tells us how many CUs there are in Arden. It also tells us bus width (matches E3 video reveal - 320bit), ROP count and that in fact it does have VRS/RT.
It also tells us there are two BC modes for Arden, GEN1 (XBX) and GEN0 (Xbone). Sparkman only has one (GEN0), which makes sense, I doubt that one will emulate XBX.
In addition to this, both Arden and Sparkman blocks (literally different parts of GPU tests) are "owned" by same AMD team members (in comparison to say...Oberon).
Now, you not believing Arden is XSX is completely different issue, and the one I am not going to entertain answering.
