If you can avoid using a new one, I would. I would not buy or use an unused 13th gen or 14th gen Intel CPU until Intel completes their updates.
In my case, there was a period of time where I had an old, damaged 13th gen CPU, and a new, unused 14th gen.
I was always able to use my damaged CPUs without problems as long as I booted up Linux and told it to use only one core (maxcpus=1 on the GRUB command line passed to the kernel). Even two cores enabled, and it couldn't even boot towards the end, but I never saw corruption with one.
If I could rewind time, I would continue to use my old CPU and avoid using the new one. I would add maxcpus=1 to my Linux command line (to do it every boot, edit /etc/default/grub, run
sudo update-grubon Debian-family systems). And I'd use the damaged CPU on a single core until I know that Intel has a workaround in microcode, my motherboard has the relevant BIOS update applied, and then l'd swap in the replacement CPU).If I didn't have a known-damaged CPU, just have a still-working 13th or 14th gen processor and could get by using an old desktop or laptop or something until the update is out, I'd probably do that if at all possible, so that I don't incur damage.
