Which is Faster with Photoshop CS6? 12-Core or 6-Core Mac Pro?
I have both a 12-core and 6-core Mac Pro, both running at 3.33 GHz, thus making for a perfect apples-to-apples comparison of whether 12 cores are better than 6 cores for common Photoshop operations.
See also the extensive comparison review of Mac Pro models still 100% relevant on a comparative basis — done back in 2010.
