The new iMac has changed the game quite significantly, with Apple skipping 4K and heading straight for 5K to make this not only the Mac to have, but the desktop computer to own. It only comes in the 27-inch variety for now and sports a 3.5GHz quad-core Intel Core i5 (boosted to a blisteringly fast 3.9GHz as an option) and a 1TB Fusion Drive. There’s also 8GB of RAM and an AMD Radeon R9 M290X with 2GB video memory. The range elsewhere hasn’t changed for now, with two non-5K 27-inch models available and three 21.5-inch models. The high-end 21.5-inch model and both 27-inch iMacs feature quadcore Intel Core i5 processors up to 3.4GHz, and Nvidia GeForce 700 series graphics with twice the video memory and up to 40% faster performance than before.
