Information Detail

The NVIDIA GeForce MX350 is an entry-level GPU designed for thin and light laptops, delivering significant graphics performance improvements over the processor's built-in iGPU. The GPU is based on the Pascal architecture with 640 CUDA Cores, and features 2GB or 4GB of GDDR5 memory with 64-bit bus width. The MX350 is generally used for light graphics tasks such as photo editing, light video, and casual gaming, and provides GPU acceleration for CUDA-enabled creative applications.

But in this particular test, a portion of the video memory (VRAM) on the GeForce MX350 was configured as a VRAMDisk. The concept of a VRAMDisk is similar to a RAMDisk, but it uses the VRAM of the GPU as a super-fast storage medium. VRAMDisk allows the creation of temporary, high-speed drives that can be utilized for technical experiments, speed testing, or graphics caching in certain scenarios. Although its capacity is limited and volatile (data is lost on reboot), the high bandwidth and low latency of VRAM provide compelling performance in certain contexts.

The tests were conducted on a Lenovo IdeaPad Slim 3i 14ITL6 laptop with Intel Core i5-1135G7 processor, 12GB DDR4 3200MHz dual channel RAM, and Windows 11 22H2 operating system. The VRAMDisk was created from a 2GB GeForce MX350 GPU, with virtual disk sizes of 1GB and 1.5GB, using special software called GPU RAM Drive.

Benchmark results with CrystalDiskMark recorded read speeds of 1113.58 MB/s and write speeds of 995.48 MB/s, showing the high bandwidth potential of VRAM as a temporary storage medium. Although the performance does not match DDR4-based RAMDisks, VRAMDisks remain a unique and attractive solution for certain technical purposes, especially for users who want to utilize idle VRAM for fast I/O processes. With its dedicated laptop GPU form factor and PCIe x4 Gen 3.0 interface, the GeForce MX350 VRAMDisk opens up new exploration possibilities in the world of experimental graphics-based high-speed storage.
