AMD’s latest Ryzen 3D V-Cache processors are gaining attention for potentially rivaling the fastest PCIe 5.0 SSDs on a RAM disk. On these processors, a RAM disk can achieve sequential read and write speeds that outperform traditional storage drives. The results are remarkable, but practical implementation and widespread usage face limitations due to specific requirements and the small size of the 3D V-Cache.
Albert Thomas, a cooling expert, recently made headlines for a screenshot illustrating a RAM disk’s performance on an AMD Ryzen 7 7800X3D processor. The image exhibited sequential read and write speeds of approximately 178 GB/s and 163 GB/s, respectively.
This fascinating discovery prompted further investigations into the practicality of achieving such speeds.
Unlocking the RAM Disk Speeds:
Enthusiast Nemez appears to have cracked the mystery of achieving remarkable speeds on a Ryzen 3D V-Cache CPU. Using the free software OSFMount and specific settings in CrystalDiskMark, Nemez achieved approximately 182 GB/s in read speeds and 175 GB/s in write speeds on the Ryzen 7 5800X3D.
Use Case Limitations and Practical Implications:
The noteworthy accomplishments should, however, not overshadow the practical implications and limitations of Ryzen 3D V-Cache CPUs. The consumer-grade Ryzen processors have a limited 3D V-Cache size.
The Ryzen 9 7950X3D has only 128MB of L3 cache, restricting its usability. Challenges arise due to factors such as inconsistent system load and the absence of a fool-proof method from AMD for implementing this technology. Widespread usage may face hurdles because of these limitations.
A Glimpse into the Future:
These findings offer an exciting glimpse into the potential future of this technology. Currently, its possibilities remain largely unexplored. AMD’s EPYC processors, like Genoa-X, boast 1.3GB of L3 cache. This showcases the potential for intriguing use cases for RAM disks in the future.
