“Although we saw the new iMac 21.5in at the end of 2012, Apple has kept us waiting impatiently for the redesigned iMac 27in,” Sasha Muller writes for PC & Tech Authority. “Thankfully, that wait is now over. It’s a stunning transformation: where the previous model was a thick slab, the all-new incarnation squeezes into a body that’s only 5mm thick at its edges.”

“As ever, the glossy 27in display is the focus of attention. It has the same 2560 x 1440 resolution as last year’s model (Retina technology hasn’t made its way into the iMac range yet), but that’s no disappointment,” Muller writes. “Put to the test with our colorimeter, the iMac’s display measures up superbly. With a maximum brightness of 437cd/m² and a contrast ratio of 949:1, movies and photographs simply burst from the glossy panel. Colour accuracy is excellent, too. With an average Delta E of only 1.6, the iMac’s display compares favourably to the best monitors money can buy… The iMac soared to a result of 1.03 in our Real World Benchmarks, just ahead of Dell’s similarly specified XPS One 27. What’s more, the Nvidia GPU delivered the best Crysis results we’ve seen from any all-in-one. At Full HD resolution and Very High quality settings, the iMac achieved a silky-smooth average of 58fps. Even upping the resolution to 2560 x 1440 was no problem: the iMac sailed through with an average of 36fps.”

Muller writes, “At $2889, this high-end version of Apple’s iMac 27in costs significantly more than its closest rival, Dell’s XPS One 27. However, the Apple surpasses Dell’s giant-sized all-in-one in almost every regard. The Dell’s display is good, but the iMac’s is sensational, and the superior GPU sees it trounce the Dell in our gaming benchmarks. If you’re in the market for the ultimate all-in-one PC, the Apple iMac 27in reigns supreme.”
