All Athlons (both Slot-A/242 and Socket-A/462) use the Alpha EV6
bus.  The Alpha EV6 bus allows four different configurations:

   100MHz DDR = 200MHz Effective
   133MHz DDR = 266MHz Effective
   166MHz DDR = 333MHz Effective
   200MHz DDR = 400MHz Effective

I'm still not sure how the whole Thunderbird v. Athlon 4 v. Athlon
MP cores fit in with each other.  I haven't hit the spec sheets to
find out the latest.  But I believe all the 1.3-1.4GHz Thunderbirds
are the Athlon 4 core.
