OK - I'm confused. What is the difference between an Athlon 64 and a 939
pin Opteron? Or the difference between a 939 pin dual core Athlon and a
939 pin dual core opteron?
I understand that the 940 pin Opterons can be used on multiple processor
boards. But I just don't get it about using a single opteron.
Also - while I'm asking - AMD Semprtons now are 64 bit - so what's the
difference between a 64 bit Sempton and a 64 Bit athlon?

939 uses unregistered memory and 940 uses registered. There are
differences in various cores, 90nm vs 130nm. 512k vs 1mb cache, dual vs
single core, number of cache coherrent hyper-transport links etc, but
memory is the key difference for the socket.

While this is an interesting subject, I ponder what it has to do on the
Linux Kernel development list.
939 pin opterons use unregistered memory and 940 uses registered memory.
Opterons in 939 pin packaging are the same as the FX- chips basically.
64bit Sempron has less cache than 64bit Athlon.
