Supposedly 'Very' different (I hope)...
Oh yes. I have a P4 here (2GHz Northwood), and two Nehalems (one 2.6GHz
Core i7 with 12Gb RAM and a 2.26GHz L5520 with 24Gb, hello overkill).
Compared to the P4s, the Nehalems are *searingly* fast: the performance
difference is far higher than I was expecting, and much higher than the
clockspeed different would imply.
But how about the core subject here - the hyperthreading? Have you
noticed anything very different wrt that? I haven't, but it will
certainly depend on your workload.
