I have a 2011 Macbook Pro which has 16GB, i7 quad 2GHz, SSD, AMD Radeon HD 6490M 256MB which I tested it against a friends early 2013 Macbook Pro which has 16GB, i7 quad 2.4GHz, SSD, NVIDIA GeForce GT 650M 1024MB. I ran the Hardware Heaven Photoshop Benchmark Tests (http://www.hardwareheaven.com/photoshop.php) against both machines. The 2011 MBP clocked in at 218.3 seconds, while the early 2013 MBP clocked in 173.1 seconds. I was surprised 2013 MBP was only about 26% faster than the 2011 MBP especially given it has a much more GPU memory. Is it because Photoshop is more CPU incentive? I would have thought after 2 years the 2013 MBP would have had seen more gains. Is anyone else surprised by these results? Do you think the late 2013 (with slower clock speed at 2.3GHz) would be even faster or about the same? I also ran a handbrake encoding of a bluray in which the early 2013 had about twice fps than the 2011. This is the kind of result I was expecting with photoshop to get about a 50% improvement. I was planning on handing my 2011 MBP to my girlfriend and getting either a late 2013 MBP or iMac. However now that I've done some comparison I'm thinking of waiting out for the next upgrade to see if performance is better.
