Chip is a program dated 1987 that can test processor, RAM, harddrive and video speed. It can also provide information about your system.

I use this benchmark as memory bandwidth benchmark for DOS. The scores recorded in my benchmarks is the RAM Throughput score. As seen in the screenshot below the score is 53092453 B/s which I record as 53.09 (53.092.453)

Screenshot made using DOSBox so results are not representative.
