Folks:
Here's a curious thing. I have a 10th gen Intel i3 CPU with four cores. When
I look at /proc/cpuinfo, it actually shows eight cores. There's a line in
the output of each core which is
cpu cores : 4
But there are outputs for each of eight cores, numbered 0 through 7.
Is it possible that there were eight cores on this CPU, and four of them
were non-working (I know it's typical to have non-working cores on a die),
and this file shows all the original cores?
Or does someone have a better explanation?
Try lscpu. Useful lines:
CPU(s): 12
On-line CPU(s) list: 0-11
Thread(s) per core: 2
Core(s) per socket: 6
Socket(s): 1
So this machine has one socket, 6 cores in the socket, 2 threads
per core, which looks like 12 CPUs.
You should find that your has one socket, 4 cores in the socket,
2 threads per core, which looks like 8 CPUs.

It appears you are correct. lscpu shows this CPU has 4 cores, and 2
threads per core. But it shows 8 CPUs. Silly.
