socket 939.
and i believe they will out perform any of current, as they'll start from 2.4GHz, as if to see 4000+ @ 2.4 and 1MB L-2. so starting Dual core will be like 2 X 4000+, that simple means 50% performance rise (as 100% cannot be due to limitation of data buses), so assumed to be 50% increase theorotically.
and as they will be on 90nm, so may be they'll feed the processors with 2MB each L2 cache makign it 4MB on one chip.
