Reviewers valued the sharp 5K display and capable performance for photo, video and general creative work at a lower entry price. Its modest processor and graphics reductions were less noticeable than the slower standard hard drive. Faster storage and more memory were useful upgrades for demanding work.
Fixed 3.3 GHz quad-core Intel Core i5-4590 with Turbo Boost up to 3.7 GHz; exact chip identified in Macworld and The Register's tests. Apple's configure-to-order section is headed 3.5 GHz and repeats options from the higher model; those processor options are excluded from this entry.
