The 2021 iMac captivates with its vibrant colors, razor-thin 11.5mm profile, and the groundbreaking M1 chip, delivering exceptional efficiency and power. With the 21.5-inch model discontinued, the choice boils down to this 24-inch stunner or the 27-inch 2020 refresh. Is the extra screen real estate worth the higher cost? As someone who's tested both extensively, let's compare key factors like display, performance, ports, accessories, customization, colors, and more to help you decide.

Screen size is the most noticeable upgrade. The 2021 iMac's 24-inch Retina display boasts 4480 x 2520 resolution—sharp and immersive for everyday use. However, it falls short of true 5K. The 27-inch iMac delivers a superior 5120 x 2880 5K panel as standard, ideal for professionals needing maximum detail.
Performance-wise, the 27-inch Intel model edges out in multi-core tasks like video encoding or 3D rendering, making it preferable for heavy media production. For most users—web browsing, photo editing, or light creative work—the M1's single-core speed and efficiency dominate, often without needing those extra 3 inches.
If port variety matters, the 27-inch iMac wins with USB-A, SDXC slots, Thunderbolt 3, and Ethernet. The 2021 model sticks to four Thunderbolt/USB 4 ports and a headphone jack, which might frustrate users charging older iPhones or iPads without USB-C. That said, affordable USB-C hubs bridge the gap far cheaper than upgrading to the larger iMac.
The 2021 iMac bundles color-matched Magic Keyboard with Touch ID (on higher configs or as a $50 add-on), Magic Mouse, and Trackpad—enhancing security and aesthetics. Touch ID trumps passwords: no more shoulder-surfing risks, just seamless fingerprint access unavailable on the standard 2020 Magic Keyboard.
Soldered components mean no post-purchase RAM upgrades on the 2021 iMac—max 16GB unified memory and 2TB storage. The 27-inch offers up to 128GB RAM and 8TB SSD, expandable later. If future-proofing heavy workloads is key, invest accordingly; otherwise, spec wisely upfront.
Seven eye-catching finishes—pink, green, blue, and more—bring personality to any space, echoing classic iMac vibes. Silver remains for traditionalists. These hues aren't gimmicks; they elevate home offices beautifully.
For most, the 2021 iMac suffices at a lower price, backed by long-term M1 support. Weigh customization limits against value—it's a powerhouse for everyday pros and creators alike.
