All this complexity, impressive, but still feels misguided. Nearly ten years ago Sun/Oracle put out the SPARC T7 that had 256 threads on a chip (October 26, 2015). x86 just managed that with the AMD Epyc 9754 (Jun 13, 2023).

How did they do that at 20 nm instead of 5nm ? Simpler cores.

Trying to improve single-threaded performance is really just adding epicycles and we need to just move onto more cores. Most of the time your CPU is just waiting, otherwise there wouldn't be all this focus on boost frequencies.

Slow it down it's reliably fed, get rid of the power throttling, because then it's not needed. Less surface area for bugs or attacks. An army of ants is a powerful thing.
