My Mac laptop with a Core 1 and DDR2 RAM does 2700 MB/s memory bandwidth. The Core 2 also has lower memory latency than the Opteron. That said - Intel still hasn't figured out how to do cache-coherent SMP scaling yet - the Opteron has the outstanding EV6/HTX bus and the cc-numa cache coherency logic working today. - Luke
