There's been some talk about Apple's next mobile CPU choice for either MBA or a slimmer MBP. Rumors have pegged an Intel plus Nvidia for at least the 15" and up models. Nothing strongly rumored yet for MBA/13"MBP.
Anandtech have now benchmarked these two processor classes. Unfortunately I don't think they were able to benchmark the only 2 Intel CPUs that seem viable (at present at least) for the next MBA, ie the Core i5 3427U and Core i7 3667U (both 17W TDP, 1.8GHz 2.8 turbo, 2.0GHz 3.2 turbo respectively), and I don't think AMD's ULV ones are there, but these results should give us a decent indication as to strengths/weaknesses in the class.
As expected really, Intel's Ivy Bridge CPUs seem to outperform AMD's CPU but AMD's integrated GPU Trinity 7660g outdoes Intel's HD 4000. The really disappointing thing for me is the battery with Anandtech saying:
"Weve only looked at one Ivy Bridge laptop so far, but if the pattern holds than Ivy Bridge will generally be a moderate step back in battery life relative to Sandy Bridge, giving AMD an even larger lead in this area."
Note that the HD 3000 corresponds to Sandy Bridge, the Ivy Bridge HD 4000 lagging at the bottom of battery tests.
