This video is all about 386 FPUs / Math Co-Processors.
I used again my M326 v5.2 M/B that intergrates an AM386DX CPU.
Fully optimized and tuned with 0WS memory up to 50MHz+.
In the Video:
1) I compare 4 different models. The latest ones from the major players: Intel (A80387DX-33), IIT (4C87DLC-40), ULSI (US83C87-C), and Cyrix (CX-83D87-40-GP).
2) Overclocking and Benchmarking with a very competitive Quake run result.
Benchmark results:

FPU Benchmarks:
In the end... I messed up the Quake measurements (only 0.1 FPS accuracy).
It is possible to divide the Frames by the Seconds and get an accurate FPS score.
