Early reports of the performance of CPUs sporting this new socket indicate that their performance is quite a bit less than what we’re used to from a similarly configured socket-939. This is surprising since DDR2 provides more bandwidth, so should in theory also be able to offer better performance. However some report a reduction in performance by as much as 50%, that’s no small margin to be honest.
I am not too sure about a performance decrease, but Hardware Analysis has some interesting points. Check it out right here.
