The two machines tested here are the fastest possible CPUs as of late 2015. The iMac 5K as tested here is well into Mac Pro pricing territory, approaching $4K as configured, though of course it includes the display.
IntegrityChecker(tm) v1.2.3 64-bit, diglloydTools 2.2.12b2
diglloydTools IntegrityChecker 'verify' a large set of image files (SHA1 hash). IntegrityChecker is highly optimized for multi-scaling nearly perfectly out to 12 CPU cores, so I/O speed is the gating factor. Here the mix of files limits CPU core usage to about 1.5 CPU cores.
This test is a real-world task performed regularly by your author. Since IntegrityChecker has few peers in its high level opf optimization for CPU core usage, drive speed is the gating factor .
The late 2015 iMac 5K with its rocking fast SSD trounces the Mac Pro. Wow. Lloyd lusts over one of these flash drives in the 2013 Mac Pro. Between IntegrityChecker and 'git', this fast flash drive makes a huge difference.
