Thanks to OWC, I’ve now had a chance to compare the new 15" MacBook Pro 2.7 GHz (with hi-res anti-glare screen) to the Macbook Pro with Retina Display.
I’ve posted my findings in my review of the June 2012 15" MacBook Pro.
Both machines had a 2.7 GHz CPU option, so the direction comparison was on level ground. The results show that the regular 15" model is no less fast than the Retina model, though the higher-res screen of the Retina model appears to make Photoshop take a very small performance hit.
