That would make sense, but when has Sun's MPU group ever made complete sense? :-p However, you're not really "shrinking" N3 if you ADD cores.

Thing is, they have a adequately-performing core that's engineered for 8 threads per core, so why abandon the many thread idea for dual thread? Why not just beef up the cores?

My guess is that N3 is very similar to Rock but w/out the scout threads and SMP.

Still, it is puzzling.
