how many regular sized GPU (say 4080 or nvidia L4) dies can be cut out from a full-sized wafer? I suppose thats what OP means by reaching integration density of 1T GPU.
- denimnerd42 3y agohere's some discussion about yields for H100 per wafer. I'd assume a 4080 is smaller? regardless, the calculator is supplied. https://news.ycombinator.com/item?id=38588876 https://news.ycombinator.com/item?id=38588876
- moralestapia 3y agoI think the whole premise of TFA is flawed, as there already chips with way more than a trillion transistors (as GP points out). Arguing about what is the size limit to consider something a GPU or not is a bit like bikeshedding. As to why wouldn't a supercomputer be considered for this? Because it's not a single chip.
- IshKebab 3y agoIt's somewhere around 20 if you go as large as possible IIRC.
- ksec 3y agoAt close to reticle limit of around ~810mm2, you could fit around 65 chips.
