There's been a fair bit of comparison of Geekbench scores for the nMP against other Macs, particularly for the 4-core nMP which has a similar score to the higher end rMBPs and iMacs. Obviously Geekbench doesn't tell the whole story, as it doesn't seem to take memory capacity, GPU etc. into account, nor does it appear to test "long term load". One of the advantages of the Xeon would seem to be its much higher TDP when compared to the iMacs and especially the Mac Books. In theory, this should mean that CPU turbo speeds can be maintained for much longer periods. Does anyone know how much effect this has in most "real world" applications? Not everyone will be doing multi-hour video exports or running calculations for days on end, where obviously sustained CPU speed becomes very significant. In other words, how quickly do iMac & rMBP CPUs find themselves throttled, and would the nMP suffer significantly less from this? I would like to have seen AnandTech run comparison of the 4-core nMP against the other Macs, rather than the fully-loaded 12-core version, which is going to appeal to small minority. Maybe someone else is working on this? John.
