AMD K5 PR166

Same as the K5 PR133 but 16MHz faster.

The K5 PR166 is the second fastest AMD K5. AMD manufactured very few PR200-models but quickly stopped to avoid creating a situation in which the K5-PR200 would compete with AMD's own, and then new, AMD K6.

All in all the AMD K5 wasn't popular. It was late to market, expensive to produce and had plenty of competition by Cyrix and Intel. Performance-wise the K5 runs well if you rely on integer calculations. The K5's floating point unit is weak compared to the Intel Pentium so you'd better not try playing Quake on these ;). Doom, however, runs great!
