What gets me is the article on Tom's Hardware about the configuration requiring a core change for the 12GB models and other component changes over the 10GB model. What? My specialty is definitely not computer architecture or chip design; however I have played with the idea of increasing video RAM by adding an additional module on the PCB that was left vacant. Surprise surprise; I wasn't the only to think of it. It was done by a modder that had previously performed the hack/mod on a previous generation GPU. On a 3080, it required some BIOS hacking IIRC, but that was it. The writer and most of the community is steaming. Whatever; from what I recall, the 3090's hadve RAM mounted on both sides of the PCB because of the lack of 2GB modules. Many many woes were cleaned up in the release of the 3090Ti which I believe carries over to the 4000 series. I post this tidbit, because these 20GB models according to availability had to have been released much later during the shortage and scalping. This ignorant rhetoric has gone too far folks. That author posted hogwash about what an extra 2GB required. Common sense says it was already in the works. Youtube gaming influencers for the most are rumor mill folk with some if not many being competent testers and reviewers. How many have programmed in VHDL, taken computer architecture at an engineering graduate level, or even designed a basic adder or understand a scheduler or even NAND implementation? Leave out the fill and stick to the rumors leaving design speculation and its implentation to those with the background to do so. Even then, it could be a crap shoot, because you were not part of the engineering or design of such a complex development.
