Utilizing the favored CrystalDiskMark benchmarking suite, Twitter/X consumer @GPUsAreMagic posted a end result showcasing some fairly unbelievable outcomes – a learn pace of 182 GB/s and a write pace of 175 GB/s. You may suppose this was both pretend or the app glitching, however with the tag CrystalCacheMark, the end result comes from utilizing the 32MB of 3D V-Cache on the Ryzen 7 5800X3D CPU as a RAM disk.
Certain, with a capability of 32MB (out of a complete of 96MB of V-Cache on the 5800X3D), you are not speaking about a lot in the way in which of storage, however 182 GB/s is the form of learn pace that makes the most recent SSDs appear like floppy disks from the Eighties. We’re blown away by PCIe Gen 5 drives hitting 12GB/s, so seeing 182GB/s is insane.
Organising and utilizing the CPU’s restricted 3D V-Cache as a storage system requires an OSFMount instrument, which permits RAM disks to mount picture recordsdata in numerous codecs. Not solely that, however exact CrystalDiskMark settings wanted for use.
These settings embrace utilizing a particular SEQ 256KB check with a queue depth 1 with 16 threads. Once more, with 32MB getting used, it’s miles from sensible, however utilizing L3 Cache as RAM disk storage is not that far-fetched. That’s for those who’ve received piles of Scrooge McDuck-like cash sitting round. AMD’s tremendous high-end EPYC Genoa-X processors pack over 1GB of L3 Cache, which is sufficient storage to be thought-about workable.
Organising devoted RAM disks has turn into a factor of the previous due to the arrival of quick SSDs, so it is nice to see the expertise being put to nice use – even when it is extra ‘attention-grabbing’ than anything.
