bit_user DS426 said: So speculative execution but for memory? Speculative memory? There have always been some predictive I/O optimizations, like read-ahead. It's just that I don't know how sophisticated they've gotten in the realm of virtual memory. The last I heard about predictive page migration was in reference to CXL, where you might have fast (i.e. high-bandwidth, low-latency) memory close to the CPU and then your expansion is sitting out over a CXL/PCIe bus. I figured that's what we'd be talking about, not predictive migration to/from swap. Reply
bit_user hotaru251 said: so AMD wants to increase ssd prices to "slightly" reduce amount of RAM (which totallllly is going to happen…) NAND is denser and costs less per GB than DRAM. It makes sense to use it as a lower-cost substitute for DRAM, to the extent you can. Also, add memory compression into the mix, and can get even more mileage out of this technology. Reply
bit_user nrdwka said: ah optane manufacturing died too soon Optane wasn't cost-competitive or comparable in density with NAND. The two are related, actually. That's the main reason it died. Even if it were still around, it'd probably just be a tier in between DRAM and NAND, but wouldn't avoid the need or the main benefits of having that NAND tier. Seriously, you can cram 245 TB of NAND in a single drive bay! DRAM can't touch that kind of density, neither could Optane. https://www.storagereview.com/review/micron-6600-ion-245tb-ssd-review-a-quarter-petabyte-per-drive-bay Reply
hotaru251 usertests said: I don't think you even read the headline, much less the article. i did, however this also will increase ssd prices and doesnt guarantee giant infinite scaling tech giants cut back on ram as just means more growth. (and supply is whats holding them back atm) You forget that the megacorps dont care about sharing they will just keep gobbling up everything regardless. if they need less ram and more storage? just means they can buy more storage (and more ram) and split ram to even more servers.

More supply will come online to meet the demand, or demand will drop if the bubble deflates. There's been talk about High Bandwidth Flash and similar technologies for a while now so AMD is not changing the rules of the game here. Reply
