CPU Core Counts

Discussions debate whether specific numbers of CPU cores (e.g., 64 or 640) are sufficient, parodying the '640K enough' quote, while clarifying physical vs. logical cores and threads in processors.

640 cores should be enough for anyone

dedup May 18, 2025 View on HN

Depends on how you count, could be 3.xx multiplied by 16 cores.

mcguire Feb 22, 2022 View on HN

No one needs more than 64 cores?

abotsis Nov 27, 2023 View on HN

640 cores ought to be enough for anyone!

moelf Dec 6, 2021 View on HN

more like 3650 cores/threads

bpicolo Nov 18, 2016 View on HN

It's logical cores vs physical cores.

wmf Jul 24, 2012 View on HN

Does 8 cores mean 8 cores or 4 cores/8 threads? The documentation is confusing.

shmerl Apr 23, 2023 View on HN

Yeah, the point is about 16 core one.

mseidl Dec 11, 2019 View on HN

More cores isn't necessarily better.

jebblue Mar 19, 2013 View on HN

That's only 4 cores. I'd rather have the cores.
