I have three of these CPU's: my first one turned out to be defective. This particular CPU is the most recent mP6 I added to my collection. It's identical to the others but it has been manufactured in the 'unusual' week 53 .

Today AMD and Intel are the main suppliers of x86 CPU's in the world. Back in the day you had more options including Cyrix, IDT and Rise. Those companies were not the so called second suppliers that made clones of existing CPU's, but they had their own x86-design. > Read more

Same as this mP6 266 but functional! I bought this CPU because I wanted to test and benchmark the mP6 and my first attempt to obtain the mP6 practically failed because I got a defective CPU. > Read more

Another player in the x86 that didn't make it. Rise developed on the mP6 for years and finally launched it in three sorts; a PR200, PR233 and PR266 model. I have the latter.

I can't tell the performance of this CPU because mine doesn't work. Because Rise was out of the market again quickly, the L1 cache is only 16KB and it's just difficult to create a good competitor against the K6 and Pentium MMX I can imagine the performance is not going to be astonishing. The only thing the Rise mP6 has in it's favor is a 100MHz FSB. > Read more
