Ok I felt I couldn't wait any longer for the Anandtech benchmarks This is a comparison of the 2010 11" (1.6GHz Core 2 Duo) and the 2012 11" (2.0GHz Core i7), both Ultimate specs. I didn't have the 2011 model so I can't compare but I had the 2010 one and the bad news for me is the 2010 1.6GHz Core 2 Duo is quieter and definitely cooler given similar workloads (eg internet browser tabs including youtube HD vids) than the Ultimate which is the 2.0GHz. This is already very evident. The good news is that, as immediately and definitely noticeable the heat is, the Core i7 in the 2012 model eats alive 1080p youtube and even 4k to an extent. On 2010, there was regular skipping when playing 1080p youtube, on this one? None. 4k even runs much, much more smoothly, with occasional skipping (again, 4k resolution). Will post more impressions as/if they come.
