hyperthreading on the i5

[jamisonbaines]

browsing the geeknench scores of different new macs i see that the 13" mbp lists as 2 cores, 4 threads (for both i5 and i7)
the 15 and 17" mbp's similarly list 4 cores 8 threads on the new i7 quads

the new i5 imacs however list as simply 1 processor, 4 cores.

so is there a fundamental difference between the imac quad i5's and the 13" mbp's dual core i5's or is it just the way it is described on the results browser?

i'm looking at the 13" mbp (wish they offered 1440 x 900) and the entry level 21.5 imac and trying to make a decision. (thoughts of the 15" mbp or 27" imac but it'd be a strain on my budget)

The mobile dual core i5s have hypterthreading, while the desktop quads don't.

The iMac's i5, due to 4 PHYSICAL cores has a significantly better performance then the 4 VIRTUAL cores of the i5 in the 13" MBP.

if you need processing, graphics power and a big screen go for the iMac. The 6750M in the base 21.5" is a very good card, whilst the Intel HD 3000 is good enough but not if you need a fair amount of graphics performance. Which one you choose will probably depend if you need to be portable or not.

You can choose a BTO option of the i7 in the 21.5" (second standard config), then you will have 4 physical, 8 virtual cores. Due to the 2.8Ghz you would have a much quicker CPU then in the 15" and 17" MBP's.
