I understand that in the future, all Athlon processors (not just the
Duron) will be socket A based.
It was explained to me thusly:
Using .25 micron process to manufacture CPU die, you can not put the L2
cache on the same die as the processor. It will over heat. It's also
difficult to put it on the motherboard, since you don't get very fast
access going through the contacts in a socket or slot. So, slot modules
were used to place the L2 cache in a convenient place for high speed
access from the CPU. However, AMD has a new fabrication plant in Dresden
that will begin manufacturing die using a .18 micron process. At that
size, AMD can put the L2 cache on the same die as the processor, boosting
the speed of the L2 cache, reducing the size of the required die, and
eliminating the need for a slot module. Because socket based processors
require less material than slot modules, they're less expensive.
When you go to buy an SMP system with Athlon processors, which should be
available near the end of this year, those processors will sit in a socket
A.
