The 27-inch iMac scored 19,588 on the Geekbench 4 performance test, blazing past top performers such as the Surface Studio (13,197), the XPS 27 (14,586) and the Zen AiO Pro (11,187).įile-transfer speeds were just as stunning, thanks to the iMac's SSD storage. The new components combined for an excellent multitasking experience, never missing a beat as I had 20 browser tabs open, with YouTube playing trailers and music and software downloading in the background. Although the base model of the iMac comes with Apple's Fusion Drive, our unit was outfitted with a 512GB solid-state drive, giving it a slight boost in performance. As in the past, the iMac's four SO-DIMM slots are accessible to the user, so you can upgrade the memory after purchase. Our review unit boasted a Kaby Lake Intel Core i7-770K processor and 16GB of 2,400-MHz DDR4 memory. When I watched the trailer for Star Wars: The Last Jedi, the iMac got loud enough to be heard outside our sound-dampened lab facility. Bass-heavy tracks, such as Kevin MacLeod's "Fearless First," sounded rich and full. It's a small problem, but when the rest of the system is so polished and pristine, it feels like a major oversight.Īpple hasn't made any public comments about changes to the iMac's audio, but the high-quality sound likely didn't need much improvement. Unfortunately, to charge the Magic Mouse, you still have to plug the Lightning cable into the bottom of the mouse, which is an awkward and inelegant design choice that also renders the mouse unusable during charging. The glass-surfaced Magic Mouse 2 still feels great and offers excellent tracking and clicking that perfectly balance pressure and feedback. The Magic Keyboard is still slim and immaculately designed, with decent keys that allow for moderately comfortable typing. The iMac still comes with the Magic Keyboard, the Magic Mouse 2 and a Lightning-to-USB cable to charge both. It's even more accurate than the previous iMac (2.2). That's better than even the best all-in-one displays, like the Asus Zen AiO Pro (0.28), the Microsoft Surface Studio (1.0), the Dell XPS 27 (5.06) and the Lenovo IdeaCentre AIO 910 (1.8). That's much better than the category average (141 percent), but color gamut is one area where competitors give Apple a run for its money - both the Surface Studio (181 percent) and the Dell XPS 27 (187 percent) produce even more colors.Īpple's display is also worthy of praise for its nearly perfect color accuracy, with a Delta-E score of 0.06 (0 is ideal). The iMac's vivid display reproduces an impressive 167 percent of the sRGB color gamut (we consider 100 percent to be excellent). To goose the display just a bit more, Apple dialed up the brightness and increased the number of supported colors from millions to a cool billion. ![]() While 4K displays have grown in popularity over the past few years, almost no one has tried to match the 27-inch iMac's Retina display and its 5120 x 2880 resolution. The connection also supports DisplayPort digital video output and can be used with a variety of high-performance storage devices. ![]() Thunderbolt 3 also offers better support for external monitors, letting you connect a second 5K display or two 4K displays at 60 Hz. The Thunderbolt 3 standard supports connections up to 40 GBps, and can be adapted out to nearly any port you want - HDMI, DisplayPort, DVI and more. These ports are smaller and aren't as finicky as traditional USB ports about plugging in right side up. One significant change, and the only visible change on the new model, is the switch from Thunderbolt 2 to Thunderbolt 3, which uses the USB Type-C standard. Wireless connectivity gets an iterative update to Bluetooth 4.2 wireless technology in addition to 802.11ac Wi-Fi.
