Okay HN, this is ELI5 time: is this instruction for interacting with SSDs that fit into DIMM slots?

It was the instruction for interacting with XPoint DIMMs (I wouldn't call them SSDs but whatever), but now you just use CLWB instead.

Previously you would use CLWB, SFENCE, then PCOMMIT. Now you use CLWB, then SFENCE.

From the article, there was another SFENCE after PCOMMIT.
