i dont get the difference between the M2 Opteron and M2 Athlon, because the M2 Opteron is going to have 1200 pins, and the M2 Athlon is going to have 940 pins. now if they both support DDR2 as the only major change, with the exception of the opteron supporting registered memory, how can the pin outs differ so much?
I mean as the memory controller is on die, the memory tracers from the DIMM slots to the two individual memory controllers would increase due to more pin outs on the DDR2 dimms, thus resulting in more pins needed on the pin grid array right?
then what is the difference between the two. with regards to the amount of pins, is there some other big difference being implemented into the Opterons being a Server based chip?
And the other changes to the CPU as in the new features like ?Pacifica Virtualization?, isnt that just changes to the CPU's logic?
