When I ran geekbench on my new m7 MacBook the score was quite low despite no other program was running. And strangely, geekbench reported that one core in my m7 is only at 1.2GHz. Pic below. Any idea? Thanks
A quick terminal check says the m7 only runs 1.2GHz
sysctl machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) m7-6Y75 CPU @ 1.20GHz

MacBook, OS X El Capitan (10.11.5)
