Anyone remember Cyrix? (Score 2)

Cyrix used to have this nifty thing called PR (performance rating or processor rating or somesuch). Their marketingspeak was that a Cyrix PR-200 would outperform a Pentium class chip running at 200 MHz. I bought that line. But of course their PR system does not take into account the dismal performance of their FPU, particularly for games, and so I found my spankin' new PR200 can barely achieve speeds of a similarly equipped Pentium 133MHz. MHz does have its problems, but so far every example I've seen of "alternate ratings" just turn out to be a lot of marketingspeak.
