Chuck,

You wrote "I would also look at adding another 256K of cache to Athlon to segment the products better and to better compete with P4 (of course the assumption is that this would have no MHz penalty - if there is a MHz penalty then I would go with keeping things as they are today)."

There is always a Mhz penalty when adding non-trivial amounts of cache at the same level. That's why all the cache on existing chips isn't simply one huge L1 cache.

I've postulated for years that as processors shrink we will see increasing levels of cache on-chip. By levels, I do not mean size, I mean L1, L2, L3, etc.. I would not be surprised at all in 2010 to see the average processor have 16 Megabytes of on-chip cache organized in as many as half a dozen levels.
