Hi u/timdettmers, I had a great time reading your blog post :) I just wanted to point out something that might be worth mentioning: the issue with 4090 (and probably 4080 as well) is that they won't fit in servers, specifically 4U rack mounted servers. In rack mounted servers, the PCIe slots are placed at the bottom (facing upwards), so the GPUs are placed "vertically" (PCIe pointing downwards). The 4090s are too tall for the 4U server, which makes it unusable (plus, 3.5slots for a single GPU complicates things further).
