15 days after its official release I eventually received my very own Pentium MMX 200. It was actually a kind donation of Erik Wagner from Nutek Systems USA, IL. I installed it on my system and it it ran straight away without any problems even at 208/83, 225/75 and 250/83 MHz. I am currently using it on my ABIT IT5V at 225/75 MHz with 64 MB SDRAM.
Before you start bombarding me with emails, asking why I used 205/68 instead of 200/66, or 166/66 instead of 171/86, I would like to explain the reason for it. I wanted to show most impressingly, that under some conditions the Pentium MMX 166 is even faster than a slightly tuned Pentium Classic 200 at 205/68. Hence I used the slowest Pentium MMX to compete against the fastest official Pentium Classic at turbo frequency.

The most impressive performance Advantage of the new Pentium MMX CPUs are reached when running normal Windows applications. At the same CPU speed, the Pentium MMX shows a performance advantage of 16% over the Pentium Classic. This is only achieved by the new cache size and design, the branch prediction unit , the enlarged pipeline and all the other enhancements besides MMX. The performance advantage could be much bigger with image processing applications that are using the new MMX instructions.
For people who are using lots of Windows business applications, the Pentium MMX is certainly worth getting. Even the Pentium MMX 166 is already 5% faster than a maxed out Pentium Classic 200 at 205/68 MHz.
