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.
