Photoshop CS6: MacBook Pro Retina 2.7 GHz vs MacBook Pro 17" vs Mac Pro
I’ve been asked to run GeekBench or XBench on the new MacBook Pro.
But the ONLY thing that matters is real-world performance on actual real workloads. Benchmarks are correlation only, and are thus useless for making a decision like “should I upgrade my computer”. That depends on what it’s used for!
Buying a Mac of any kind and/or want a LOW PRICE on AppleCare?
Thank you for using my gear pages to buy thru B&H (preferred) or Apple.
Max memory matters for some jobs!
Read my Photoshop CS6 speed tests and RAW file conversion speed.
Memory matters when the job gets larger, and the MacBook Pro breaks down badly with its 16GB max memory on bigger jobs (diglloydMedium).
A fast CPU is fast only if all computing is in memory and not hitting the disk (for any reason— paging, scratch use, etc). In the real world, not having enough memory matters far more than small CPU speed differences, as the diglloydMedium benchmark sh0ws below (which includes Photoshop tasks I use almost every day).
