Interesting: While the Cinebench R11.5 OpenGL benchmark shows no significant advantages for the i7 CPU (19.63 vs. However, we cannot determine a worse thermal behavior of the i7 CPU because of this. Typical clocks in the benchmarks were between 750 and 900 MHz.Ĭompared to the similar MacBook Air Mid 2013 with the i5-4250U CPU the clocks are consequently higher but the chip reaches critical temperatures quicker, which leads to a reduced turbo clock. We were able to squeeze up to 950 MHz out of the GPU in the Unigine-Heaven benchmark, but the clock was often reduced because the temperatures were very high between 95 ☌ (203 ☏) and 99 ☌ (210.2 ☏). The consequence is a lower clock between 650 and 750 MHz. The turbo clock of the integrated HD 5000 graphics is raised up to 850 MHz in the Cinebench R11.5 OpenGL-Shading test but the chip reaches a core temperature of 99 ☌ (210.2 ☏) (HWInfo) after a few seconds. The chip reduces its clock to 800 MHz during idle. The MacBook Air reaches 2.7 up to 2.9 GHz at the beginning of the multithread benchmark, but once again the clock fluctuates between 2.3 and 2.9 GHz after a couple of seconds. At least at the start we determined 3.3 GHz for fractions of a second before it leveled off at 2.9 GHz after a few seconds. During our benchmarks the clock fluctuated between 2.7 and 2.9 GHz the promised 3.3 GHz were only utilized in the SuperPi benchmark.

As mentioned before the maximum turbo clock of the Intel Core i7-4650U CPU is 3.3 GHz, which is also advertised by Apple. The i7-4650U processor shows a similar behavior: The maximum clock was 2.9 GHz for the single thread benchmark of Cinebench R11.5 and Windows operating system (via Bootcamp). Even the i5 CPU had some problems with the turbo clocks the maximum clock of the CPU was rarely used.
