MLID said the 4090 is 60 to 80% faster than the 3090, not the 3090Ti, that prediction initially came from AMD insiders who predicted that themselves, who also said its what they are aiming against with RDNA 3 and what they can work with, what that means exactly i don't know.
Reviewers he's talking to have confirmed that is bang on, Nvidia's own slides say its on average 65% faster than the 3090Ti, those same reviewers also say its about 100% faster than the 3090 in RT.
I'm saying 50% faster that the 3090 because i think AMD can achieve that at least, i also think the RT performance is still going to lag some way behind the 4090 but will be much better than the 3090.
IMO a lot of reviewers will see that RT performance as not good enough and declare it a damp squib, with that i don't think AMD can charge much more than $1000 and even at that the market share will remain unchanged, the 4090 will be a runaway success and so the 5090 will go up to $1800 if not $2000 with everything below it being pulled up too
They will all say its all AMD's fault, nothing to do with us, and we need Raja to make a Mk3 Vega.
