2013 Mac Pro: Photoshop CC Performance (diglloydHuge)
The diglloydHuge benchmark measures core Photoshop operations, the stuff your author uses every day for professional photography: sharpening, resizing, inverting, etc. It uses a very large file size that leads to memory usage of ~49GB memory. Hence performance can degrade badly on underconfigured systems.
See the test machine configurations.
With four fewer cores and the same base clock speed and less memory, the 8-core 2013 Mac Pro with 64GB memory still showsn an impressive ~23% reduction in run time versus the 12-core 2010 Mac Pro Westmere with 80GB memory (compressed memory was noted at “0.0” following the test run).
The 6-core 3.5 GHz Mac Pro is only ~5% slower here than the 8-core 3.33 GHz—barely noticeable—and note that Apple’s stock 3.0 GHz 8 core would apparently be matched and probably beaten by the 6-core.
Seen here is the dramatic impact of not having enough memory: the MacBook Pro is limited to 16GB maximum memory. The same would apply to the Mac Pro, but the 64GB Mac Pro test machines were outfitted with 64GB memory kits from OWC.
