Nice results, and easy to read graphs. Use the graphs in future lab reports. I think the main reason for the much bigger CPU boost in the 11" is that the 1.6GHz Core i5 turbo boosts only to 2.1GHz in dual core mode, while the 1.7GHz boosts to 2.4GHz and the Core i7 boosts to 2.6GHz. The extra 1MB cache has some impact, but not a lot of programs today are fully optimized for multicore usage and hyper threading (which would tend to keep the CPUs at the base speed), so the processor frequently uses turbo boost. I did a little test in Windows 7 in mine using Handbrake (and CPU-z to monitor clock speed), and during encoding it oscillated between 1.8GHz and 2.6GHz throughout, spending roughly half the time in each mode.
