Yeah, two physical chips. the differentiation between 2xx chips and 8xx 
chips is the number of unattenuated hyper-transport links that can be used 
for processor interconnects.

you can put two 2xx chips on a motherboard with two sockets reagardless of 
whether there are two or four cores involved.
