AMD Ryzen 7 5800X3D owners have posted benchmarks that show off what the 3D V-Cache of these CPUs are capable of when operating as a RAM disk.
Per benchmarks shared by the @GPUsAreMagic account, users can see ludicrous speeds of nearly 183,000 MB/s read and over 175,000 MB/s write from AMD’s 3D V-Cache CPUs, although this trick seems to work under CrystalDiskMark only.

CrystalDiskMark with very specific settings running from a RAMDisk (OSFMount) all within the 96MB L3 cache of the 5800X3D.

Here’s how owners of the Ryzen 7 5800X3D and other 3D V-Cache chips can gawk at these huge numbers:
- Install OSFMount and create a FAT32 formatted ramdisk.
- Run CrystalDiskMark, set the test values to:
- SEQ 256KB, Queue Depth 1, Threads 16
- Set data fill to 0s instead of random.
- Run the test (probably a few times, this is very sensitive to system load).
According to additional benchmarks from other testers, the speeds may even go up to 207,073 MB/s read and 179,309 MB/s write.
“Innovative 3D stacking technology to enable the world’s fastest gaming processors – the AMD Ryzen 7000X3D series – and the world’s highest-performing server processors for technical computing,” reads the marketing for AMD 3D V-Cache technology.
