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.
