What socket was it? I think all modern sockets are LGA - and even before that, they were ZIF for a long time.

AMD processors still use PGA sockets, but they are ZIF.

Really? the last opteron I saw with a zif pga socket was an opteron 940, which was obsolete a decade ago. I haven't worked with the gaming amd sockets, but I bought a tonne of 2000 series opterons, socket F is LGA, and a few c32 and G34 opterons, all LGA.

My current CPU (AMD FX-8350) is a ZIF PGA Socket (AM3+)

And AM4 ("zen" architecture, not threadripper) is a _very_ similar looking and feeling ZIF socket - total pin count might be different, I'm not sure.

The AM4[1] socket (for consumer processors) is PGA-ZIF.

The TR4[2] (for enthusiast Threadripper processors) and the SP3[3] (for server Epyc processors) sockets, however, are LGA.
