Joe,

> Their more mainstream chip Mx (or Mxi?) with 6x86 core and 64K L1 never made it to the market because the whole chip did not scale. The chip that was supposed to scale well M3 or Jalapeno (not what via is selling now as Cyrix 3) was a great concept, but never made it out of the design center. >

Based on very little but direct info I had in the past, (I think it was MXi) problems were mainly attributable to the (3D?) graphics integration. They never had the thing working in all graphic modes - different resolutions, refresh rates, etc. This is why I have doubts about Timna at high MHZ.

< The approach I would like AMD to take, if they ever go in this direction is to integrate only the memory controller, nothing else. For a mainstream market CPU that will never be used in multiprocessing environment, this would provide optimum performance. >

I agree. This is a low risk and less complex piece that can be easily integrated on the chip with the added benefit of reduced delays in the main memory interface.

Joe,

The Cyrix MediaGx suffered from the lack of L2, and tiny L1.

Actually, the lack of L2 may be the MediaGX's greatest strength. The die is small, burns very little power, and is being sold in large quantities by National.

The latest version of MediaGX burns less than 1 watt, and is very cheap. It is an ideal solution for information appliances.
