News Intel unveils Optane DC Persistent Memory

I'd complain about it being DC-only rather than available on consumer devices, but it's likely to cost an arm and a leg for the first-gen product and offer no functional benefits without all your software being re-architected - if it even can be, this isn't a magic make-everything-go-faster device - to take advantage of it. This isn't just a transparent cache you can plop into a system like consumer Optane Memory.

 

Where? When?

 

I don't have any workloads that would benefit from PM on the CPU, certainly nothing on the desktop beyond "I have my entire system running from DIMMs! Muahahaha!" bragging rights.
I'd love to have a big pile of Optane on a GPU to hold massive point-cloud datasets, but that's kind of a you-need-a-POWER-based-system-with-NVLink-backplane-to-start-with problem (and getting Optane onto an NVLink host device is probably a nonstarter for now).
