Apple’s skipped 4K and headed 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 3.9GHz as an option) and a 1TB Fusion Drive. There’s also 8GB of RAM, AMD Radeon R9 M290X with 2GB video memory. The range elsewhere hasn’t changed, 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.
