    Why are benchmarks not all the same?

    I can understand that there can be some variances (eg. different apps installed/running, OS, etc).

    But how can the same machine undergo a benchmark test within minutes and get different results every time.

    MacBook Air 2013 i7 8GB = Geekbench 6594 32bit

    MacBook Air 2013 i7 (assumed 8GB because of score) = Geekbench 7489 32bit

    What's odd is that an iOS device's results are almost always consistent!!

    If I recall, Geekbench wholly benchmarks your computer. The 256GB ssd is almost 2x faster than the 128GB drive. This could account for the large difference...

    I thought the new PCI-E SSD's were all the same speed regardless of their capacity.

    Nope... the new 128GB version is quite a bit slower in write speeds. Read speeds are about the same though.

    If you search the forums you can see some speed test from 2013 owners confirming this.

    The benchmark by geekbench 2.0 seems more a joke as mine is i5/8GB/512SSD and have never gone beyond 6858 in its i wouldn't sweat on it
