This is a real world test influenced by both CPU cores and SSD/flash drive speed.

IntegrityChecker has few peers in its optimal use of CPU cores, but the 2016 MacBook has only two CPU cores versus 4 cores for the 2013 MacBook Pro Retina.

However, the 2016 MacBook does nearly as well as the 2013 MacBook Pro Retina in spite of its turtle-slow CPU clock speed of 1.3 GHz. That’s because the run time is governed primarily by how fast the SSD is (read speed)—so its two CPU cores are fully utilized while the 4 cores of the 2013 MBP Retina remain mostly idle. The SSD in the late 2013 MacBook Pro Retina is much slower than in the 2015 MacBook Pro Retina or late 2015 iMac 5K.

Times should not be directly compared to the year prior test with the 2015 MacBook: file sizes have changed.
