Clarification:
Like the previous Athlon-C "Thunderbird," the Athlon-4 cache is 128KB
L1, 256KB L2.  It also has a wider, set-associative approach on the L2
cache over the Athlon-C that improves the hit ratio.

Another benefit of Athlon v. Intel is that Athlon does "exclusive"
caching.  On Intel, the L2 _must_ have a copy of what L1 has.  It also
has to load from memory to L2 to L1 before it actually gets to the
freak'n CPU registers, and store vice-versa!

Athlons can store/load to/from L1, L2 and memory directly.  So it has a
_true_ 192KB (Duron) and 384KB (Thunderbird/Athlon-4) "effective
cache."  Intel's is only 128KB (Celeron) and 256KB (P3/4) "effective
cache" (because L2 _must_ contain everything L1 does).

Oops!  Bad Math!
200/266*1.4GHz = 1.050GHz.
