You can create a RAM disk within the 3D V-Cache of an AMD X3D CPU if you really want to-
Now here’s something interesting, if only for interest’s sake. Twitter/X user Nemez managed to create a RAM disk held within the Level 3 cache of an AMD Ryzen 7 5800X3D processor and the results make the fastest NVMe drives look like sloths in comparison.
Nemez (via Tom’s Hardware), used the CrystalDiskMark benchmark using some specific settings and achieved sequential read and write speeds of 182GB/s and 175GB/s respectively. In comparison, a fast PCIe 5.0 NVMe SSD can achieve around 12GB/s read and write speeds, meaning the L3 cache drive is more or less 15x faster. However, The peak bandwidth of a 5800X3D’s L3 cache is up to 2TB/s, so these results are only using a fraction of its potential.
The FAT32 disk was created using OSFMount and tested with CrystalDiskMark 8.0.4 using the specific SEQ 256KB test, with a queue depth of 1 with 16 threads. Even then the test results were erratic. Of course, such a test is purely academic.
It needs to be said that using L3 c…
