Intel Core i5 4250U 

Released July, 2013
  • 1.3 GHz
  • Dual core
8.1 Out of 10

What we're seeing here is a combination of IPC improvements and awesomely aggressive turbo, all within a 15W TDP.

Last year's 2.0GHz model is about 5% quicker than this year's 1.7GHz Haswell ULT system, but obviously with the newer machine you get much better battery life.

The 2013 MacBook Air: Core i5-4250U vs. Core i7-4650U

by Anand Lal Shimpi |
www.anandtech.com
I’ve found that OS X tends to fire up the dGPU anyway while running this workload so I saw no reason to run a separate set of numbers for processor and discrete graphics.
Internal CPU Proximity Thermistor Intel Core i5-4250U 47.1 °C 41.4 °C 41.4 °C 92.2 °C Intel Core i7-4650U 47.7 °C 42.1 °C 46.6 °C 96.7 °C Average temperatures aren't substantially higher on the i7, however you will notice that there's a column for max observed temperature on the bottom of the chassis where the upgraded MacBook Air does show a considerably higher temperature.
