Cyrix' M2 was, on paper, quite an improvement over the M1R that the IBM 6x86 P200+ used. This because the M2 is made on 350nm instead of 650nm and thus uses a lower core voltage which causes much less heat generation. Despite this, the increased L1 cache (to... > Read more

Similar to the Cyrix 6x86MX PR200 but then a tad faster. This one clocks at 187MHz using a 75MHz front-side-bus so it's only 21MHz faster than the PR200 mentioned earlier. Luckily the increased front-side-bus will compensate for the slightly increased clock ... > Read more

Technically this is a Cyrix CPU but IBM sold them under their name as well. I like the dark looking heat spreader that just sits on top of the 'die' (the core). You can look under the heat spreader and actually see the 'die' along with some SMD chips. Somehow that reminds me a lot of the AMD K6-2 (w... > Read more
