Colloquially, a RAM Disk is a space for storing that takes up area in RAM. However, this observe appears more and more to be falling into oblivion… However. In reality, some little rascals have been having enjoyable exploiting the 3D V-Cache reminiscence of their Ryzen processors . The outcomes are clearly mind-boggling!
3D V-Cache: as much as 175 GB/s sequential writing!
To create a RAM Disk on the cache reminiscence of your Ryzen X3D CPU, you’ll want to make use of the OSFMount software program, based mostly on the FAT32 format. Then, to bencher this storage, we needed to do loads of fiddling in CrystalDiskMark by coming into the next parameters (Nemez methodology on x.com):
- Test values: SEQ 256K
- Queue depth: 1
- Threads : 16
- Data fill: 0
From what we perceive, it is a reasonably random course of, since it could not work the primary time, and several other makes an attempt appear mandatory. However, when it does work, efficiency is breathtaking.
On a Ryzen 5 5800X3D, sequential learn speeds reached 182 GB/s, in contrast with 175 GB/s for writes. On a Ryzen 7 7800X3D, unusually sufficient, outcomes had been slower, with 178 GB/s learn vs. 163 GB/s write.
In any case, whereas it’s enjoyable and lets you show excessive knowledge charges, in observe, there’s no actual sensible use case. For one factor, the quantity of reminiscence is basically too small: 128 MB at greatest with a Ryzen 7000. Secondly, it’s not foolproof, however it’s fascinating all the identical.
