DesignThe iMac's new, thinner design is the centerpiece of this update. It tapers to 5-mm at the edges, creating a pretty stunning optical illusion—a waif of a desktop. Using ItActually turning the computer on and using it pretty much unchanged from any other iMac before it, aside from the speed. Apple's SSD/HDD Fusion Drive hybrid keeps pace with the SSDs in the MacBook Air, for the most part. Programs like Premiere Pro CS6 or Photoshop open at full SSD speed. Same goes for file transfers within the confines of the SSD (all file transfers seem to go to the SSD by default, and then migrate to the HDD later, given I/O speeds). If you're transferring 100GB+, you're going to kick over to the HDD and see some slowdown. As for actual brute force computing prowess, in our standardized render test, the new iMac averaged 43 seconds. That came out well ahead of the Retina MacBook Pro 13-inch (54 seconds) and an older Mac Pro (2 minutes), but it was behind a Retina MBP 15-inch (34 seconds) that had double the RAM and a beefier graphics card. Real world-wise, that nudges the bang-for-buck value toward the RMBP 15, especially since its default graphics card is a little better. For gaming, our near-base configuration was fine. It's 1080p (non-Retina) screen ran Diablo 3 at 1080p on medium settings at close to 60fps. But for any heavy lifting, you're going to want to upgrade to the beefier cards on the 27-inch iMacs. If you ramp up the settings on D3 or Witcher 2, you're not going to squeeze great performance out of the baseline GT cards. Our framerate dipped under 30 on both games, in a hurry. The Best PartIt's a fast iMac. As frustrating (and Apple-like) as it can be to have basically no options for what goes where on the drive, Fusion Drive does its job well. It makes the entire OS feel snappier in ways that simple 8 or 16GB smartcache solutions don't, really. Aside from moving around huge files (videographers beware), it really feels like having your whole system running on an SSD, just with a high capacity drive. Tragic FlawThe design upgrades do little to improve the desktop experience. For most people, the biggest upgrade to usability here is the Fusion Drive, by a pretty good margin. But the slim new design does nothing for you. In fact, it gets in the way—it's nearly impossible to upgrade RAM on the 21-inch version, and the razor-thin side moves the SD card slot to the less convenient back panel. Inconvenient ports are the biggest deficiency on an all-in-one. Someday, someone's going to figure out how to do it right. But it's probably not going to be by making the machines thinner. This Is Weird...The thinner design also has the sort-of unexpected effect of making the iMac easier to budge. If you grab the edge to wipe a smudge off of it, or just bump it as you reach for something, it's more likely to shift on the table top. Test Notes
Should You Buy This?Sure. Maybe. If you want an iMac as a pretty-looking home station, there's no reason to not go for the slimmer design with better guts and the option for the fusion drive. But if you're considering this 21-inch model, be aware that it's much tougher to customize by yourself than its 27-inch counterpart. You should also know you're not getting top-end gravel-chewing performance—for that, you'd be better off with a Retina MacBook Pro. iMac Specs As TestedDisplay: 21-inch 1080p |
