November 26, 2023A fierce person who converted the 3D V-Cache of CPU Ryzen to a RAM disk appeared. This was reported by overseas media Tom’s Hardware. A user has successfully converted the 3D V-Cache of AMD Ryzen 7 5800X3D to a RAM disk. The speed is about 182GB/s for sequential read and 175GB/s for sequential write, which is ridiculously fast. Over 12x faster than the fastest PCIe 5.0 SSD. Ryzen 7 5800X3D-3D V-Cache RAM Disk Read 182GB/s Write 175GBs RAM Disk According to Nemez, he used an app called OSFMount to create the RAM disk on top of the L3 cache. Our writer Albert Thomas also successfully converted a Ryzen 7 7800X3D to a RAM disk, confirming the truth of this story. Ryzen 7 7800X3D – 3D V-Cache RAM Disk Read 178GB/s Write 163GBs A very cool experiment, but unfortunately the cache is too small to be useful on a consumer CPU. Even the top-of-the-line Ryzen 9 7950X3D has only 128MB of L3 cache. However, an EPYC processor like the Genoa-X with 1.3GB of L3 cache could find some interesting uses.
