John,
I think you will find that the new CXT (Warpcore) is about 7% faster than the old core. That's all I can say...

John,

Adding cache to the Celeron improved Winbench scores by OVER TWO SPEED GRADES, and that was only 128K

The Celeron went from 32K-L1/0K-L2 to 32KL1/128K-L2. K6-3 is going from 64K-L1/1MB-L2 to 64KL1/256K-L2/1MB-L3.

Celeron started with a grossly inadequate memory subsystem, and added 128K of high speed L2, effectively increasing the cache size by 5X. K6-2 already has a good memory subsystem. K6-3 changes will be incrementally better.

It has been confirmed that the core of the new K6-2 'CXT' chips is the same as the K6-3.

This will cause the performance delta between K6-2 and K6-3 to diminish.

I was pondering this after our vegetarian Thanksgiving dinner last night, and it occured to me that the CXT is probably a K6-3 with the cache disabled. I wouldn't have made sense for AMD to redo the floorplanning and layout of the K6-2, with the knowledge that it was going to be replaced in a few months anyway.
