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.
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.
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?
