2x the fake news and rumoured leaks. Get ready for the usual 20-30% increase as usual. Even the 2080ti to 3080 with double the cuda count was max 30% faster than a 2080ti, just people forget the reality. This time we are not getting a doubling of cuda cores and higher power limits tells you it will not be nowhere near 50% even and if we get 50% it will be the 4090ti not the 4080 or 4090 as we saw this gen and this 3000 gen was supposedly their largest increase in years (take that with a huge pinch of salt).
4080 will be 20-30% max faster than a 3080 and will be on the 103 chip.
4080ti will be same as 4090 minus 3 to 5 % slower and half the VRAM and will be on the 102 chip slightly cut.
4090 will be 30-40% faster than a 3090 and come with 16pin power on standard models and some AIBs with 2 x 16pin power basically silly power use on the AIB OC models. 102 chip slightly cut.
4090ti will be aiming for 50% faster than a 3090 but really 40% faster max than a 3090ti and stupid power use with 2 x 16pin power on the AIB models with OC. 102 chip fully unlocked.
The midrange will see smaller increases as we saw this gen, 4070 will probably be only one aiming for 20-30% increase and ones lower down 3060,3050 will see a max 20% increase if we are lucky.
The main thing Nvidia needs to fix is the VRAM size issues on their 4080 and not do the silly low VRAM again, they only did that on the 3000 series because AMD forced their hand to move up each model one step up, this is why we got a 3080 on GA102 not GA104 so they had to do something to disable it in future games and they knew 10GB was never enough and 12GB should have been the minimum and 16GB for a 3080ti with a £1400 price but it all got messed up by AMD, even the 3090's should not exist they both should have been really the Titan cards 3090= Titan A and 3090ti Titan AP, like the titan x and xp.
I think people are in for a shock when they come out and the power use and price for performance that will make all these rumours look so stupid as we saw with AM5 CPUs and people again were saying 50%-100% increase over AM4.. meeh reality sucks and this is why people live in dream land about 2x the performance ..from gen to gen, them days have been done for decades.
