Just installed a Samsung 970 Evo Plus into my late 2013 27" and its showing a PCIe link width of only 2x and speeds are kinda of meh. Is this normal for this model?

Yes.

Maybe a little slow, but the Late 2013 iMac only has two lanes of PCIe 2.0, which is about a max of 1GBps.

Is there something going on with the drive that is making it a little slower? Did you just install an OS on it, if so, then maybe there is some indexing going on with the drive. Test it again in a day or two.

Just for reference, I have posted the speeds of a Samsung X5 NVMe Thunderbolt 3 external drive as a boot drive on a Late 2012 iMac, and the speeds were slightly higher than what you posted for your Late 2013 iMac.

OP:

Considering the age of the iMac, the speeds you're seeing are about what one would expect to see.
Actually, not bad at all.
