Re: Power draw is going to get higher with new transistor types
> According to IBM research, nanosheet transistors (the type being employed by TSMC for N2 and Intel for 20A/18A, though each have their own marketing names) which will appear on the server market in 2026 or so double their performance level if you cool them to LN2 level temperatures.
> Since cooling to that level is relatively cheap it is an easy decision to make for doubling performance. I don't know how much additional input power the chip requires, but safe to say it will require higher power levels. So datacenters are going to become even more power dense by the end of the decade!
I've not followed this for several years so I don't know what the current state-of-the-art is, but at CERN we've been experimenting with/using carbon-dioxide evaporative cooling for years Here's an early article which was my first DDG search result. More papers are out there if you use the right keywords.
