You can bet your bottom dollar they've done the same.
The vid I watched yesterday comparing the performance of the 2080ti to the 3080, this guy has ran doom eternal and it's about the same as a 3080 with his clocked up 2080ti.
While it's progress being the fact it's half the price and so it should be 2 years down the line the performance increase over 2 years is not what they are making out or should be.
Make of that what you want but the fact is this isn't progress for 2 years development.
I'm now waiting and not purchasing to see what happens next year.
Was hyped for the 3080 but it's already not sounding like the red rose tinted glasses Nvidia wants everyone to think.
