Apple iMac A Grade Desktop Computer 27-inch 3.8GHZ 8-Core i7 MXWW2LL/A 2020, 16GB, 1TB SSD, Radeon Pro 5500 XT, Silver

The 2020 27-inch iMac nails reliability at the 99th percentile and has a stunning 5K display, but the 16GB RAM at the 32nd percentile and WiFi 4 hold it back. At $912 USD, it's a good buy for Apple fans who want a dependable all-in-one. Just don't expect it to be a performance monster.

The i7-10700K (or non-K, Apple's binning here is a bit fuzzy) with 8 cores at 3.8GHz lands right at the 50th percentile for CPU performance. That's about average for desktops in our database, which means it'll handle everyday tasks, photo editing, and light video work without breaking a sweat. But don't expect it to crush heavy renders or compile massive codebases. The Radeon Pro 5500 XT with 8GB of VRAM sits at the 66th percentile for GPU, which is a step above average. It'll push that 5K display fine for UI work and handle 1080p gaming at medium settings, but it's not a 4K gaming card by any stretch.

The 1TB SSD at the 54th percentile is fine, nothing special. Read and write speeds will feel snappy for most tasks, but it's not going to win any speed contests against newer NVMe drives. The 16GB of RAM is the weak link here at the 32nd percentile. For a machine marketed toward creators, 16GB is tight in 2025. You'll feel it if you're running multiple Adobe apps or a bunch of browser tabs alongside a heavy project.

Stacked against the Lenovo Legion Tower 5a Gen 10, this iMac loses on raw performance. The Legion likely has a newer Ryzen or Intel chip and a beefier GPU, plus actual upgradeability. The HP OMEN GT16-0364 and MSI Aegis ZS2 are gaming-focused machines that'll crush the Radeon Pro 5500 XT in frame rates. But none of those include a 5K display, and none of them touch Apple's reliability numbers. The Dell ECT1250 is probably the closest in spirit, a business-focused desktop, but it won't have the same display quality or build feel. If you need a monitor plus a computer, the iMac's all-in-one nature starts to make more sense. If you already have a monitor, skip it and get a tower.

At $912 USD, this refurbished iMac is a decent deal if you value that display and Apple's build quality. The 99th percentile reliability score means you're buying a machine that'll likely keep humming for years. But the value proposition gets murky when you look at what else is out there. The Lenovo Legion Tower 5a Gen 10 and HP OMEN GT16-0364 offer newer CPUs and better upgrade paths for similar money, though you'd need to add a monitor. If you're already in the Apple ecosystem and want a big, beautiful all-in-one, this is a reasonable buy. Just know you're paying for the display and the logo as much as the internals.

The 2020 27-inch iMac with the 3.8GHz 8-core i7 is a bit of a mixed bag on paper, but that reliability score is the headline here. It sits in the 99th percentile for reliability in our database, which is basically Apple saying 'this thing will outlive your houseplants.' The 5K Retina display at 5120 x 2880 is still gorgeous, and the Radeon Pro 5500 XT with 8GB of VRAM gives it enough muscle for most creative work. But the overall score of 53.3 out of 100 tells you this isn't a powerhouse by 2025 standards.

The 16GB of DDR4 RAM lands in the 32nd percentile, which is mediocre for a machine at this price point. The 1TB PCIe SSD is solid but middle of the pack at the 54th percentile. And the port selection at the 41st percentile is underwhelming, especially when you look at what modern desktops offer. Still, for $912 USD, you're getting a lot of Apple polish and that display alone is worth a chunk of change.

Skip this if you need serious compute power. The AI and LLM score of 33.6 out of 100 is a real letdown, and the 16GB RAM at the 32nd percentile will frustrate anyone running virtual machines, heavy video editing, or large datasets. Gamers should also look elsewhere, the Radeon Pro 5500 XT is a workstation card, not a gaming GPU, and WiFi 4 means slower wireless speeds than even budget laptops from the last few years. If you already have a decent monitor, a tower PC will give you far more performance per dollar.

The 2020 iMac with the 8-core i7 is a reliable, beautiful machine that's starting to show its age in the performance department. The 99th percentile reliability score is genuinely impressive, and the 5K display remains a standout feature. But the 16GB RAM ceiling, WiFi 4, and mediocre port selection make it hard to recommend for power users. For $912 USD, it's a solid buy for someone who wants a dependable Mac for everyday work, light creative tasks, and doesn't plan to push it hard. Just don't expect it to keep up with modern desktops in raw compute.
