These high power arm chips are really interesting. I feel like this is a good problem to have.

I bet someone at some point said “256 is futureproof”. We’re well into Amdahl’s Law at this point.

From the article:

Back in 2021, a patch was sent out proposing the ARM64 CPU core limit be increased to 512, but Linux maintainers denied it because no CPU hardware was available at the time with more than 256 cores.

They have submitted a patch, as stated in the 1st paragraph of the article.

The question is how long will that many cores stay niche though?
