While I applaud AMDs copious VRAM as it is needed (Listening Nvidia?) lets get real here on performance. The 6000 series was the first time AMD caught up to Nvidia in generations on the high end only to lose that race again the next generation. The time prior AMD was 'competitive' on the high end was three generations ago with the R 390 vs GTX 980 (being kind as it was well behind the GTX 980 TI). Vega couldn't keep up with the 1080 Ti but did due a better ish job, Polaris was mid range only and the 5700 series didn't come close to Nvidia's high end RTX 2080 Ti. So NO AMD was close last gen but with their current track record the last handful of generations, that is the exception not the rule. The RX 7900 XTX proved as much.
the 7900xtx is AMD 50% caught with there pants down 25% scared and 25% im going to say smart but also stupid ..
If AMD had stayed with a monolithic die like Nvidia they would have been a better competitor with the 4090 and most likely crushed ( maybe even in RT ) everything else Nvidia bought out more so than just beating them in some things ..
pants down was i think the 4090 left fielded them and they couldnt answer and which kinda ties in with the smart..
MCM i believe is the future and a good argument can be made instead of sticking with tried and true architecture by moving to MCM they have given themselves a head start on the MCM chiplet architecture at the cost of burning themselves ..
That said to compete with the likes of the 4080 4070 with a new architecture the way they have is pretty damn impressive really
scared was maybe the price after the pandemic AMD was scared to go to big because $1600 for the 4090 could have been a big fail a gamble that really did pay off for Nvidia !!
Take the 3d v cache CPU's ask yourself this how long before Intel start doing the same thing because while the 13900k is in my honest opinion the best overall cpu you can buy ( i just hate Intels socket life span hence why i stay with AMD ) once AMD can sort the 8950x3d double stacking v cache , efficiency and out right raw compute power Intel will be gone !!
3d vcache is the future !!
