X-Vesa shows information about your graphics card and is able to measure VRAM speeds using different kinds of graphic modes. You need a VESA-compliant graphics card for this benchmark.

I use this DOS benchmark for ISA, VLB and older PCI cards to get insight in their VRAM performance. Note that this benchmark is 'theoretical': it does test memory bandwidth but a high memory bandwidth is no guarantee for high performance!

The scores noted are the 32-bit write scores.
