2013 Mac Pro: SHA1 Cryptographic Hash Speed

Get Mac Pro at B&H Photo. See also MPG’s computer gear wishlist as well as diglloyd-recommended performance packages for Mac Pro.

A big thanks to Other World Computing for loaning MPG the upgraded 2013 Mac Pro! Ditto for B&H Photo for loaning the 6-core Mac Pro. 64GB memory kit for 2013 Mac Pro provided by OWC.

Introduction

The SHA1 cryptographic hash* is a compute intensive job with modest memory access so it tends to scale very well across multiple CPU cores.

* Test here from MemoryTester 'mt compute'.

Results

See the test machine configurations.

Times (in seconds here) reflect the time needed to complete a fixed amount of hashing work (BitCoin fans take note).

The 8-core 2013 Mac Pro is about 10% faster with a few cores, but the gap closes until near parity is reached at 8 cores (within measurement error).

At 9 cores and beyond the 12-core 3.33 GHz 2010 Mac Pro pulls ahead, but only by about 24% at 12 cores.

The 6-core 3.5 GHz Mac Pro lags the 8-core 3.3 GHz, which can be expected from slightly higher Turbo Boost on the 8-core. But the 3.0 GHz 8-core would run neck and neck with the 6-core.

The crossover point for the 12-core 2013 Mac Pro is 8 cores to match the Apple stock 3.5 GHz 6 core and 11 cores to match the 3.3 GHz 8-core.

Vertical scale below is 12...1 CPU cores. Horizontal scale is time in seconds to complete a fixed-size job.
