2 slot design all in one hybrid would be atypical for a vanilla flagship and has never been done before. Although that would be the most likely design unless they somehow were able to take advantage of the new active silicon cooling but doubtful they would take such a gamble with halo flagship.If the leak from kopite7kimi is true the 5090 is a Dual-slot GPU therefore it's probably Liquid-cooled like the MSI 4090 SUMPRIM LIQUID X ! If so then AIBs are going to struggle even more to make buyers want to buy theirs. I guess people who want Air-Cooling will go for AIBs but Water-Cooling is definitely going to become a Standard sooner or later if GPUs start pulling 600W+
As much as Naming doesn't mean anything the TITAN line is definitely aimed at Professionals. They have some FP64 cores that Consumer GPUs do not have, and they usually have 2x the amount of VRAM for Professional workloads too.
