Mac Benchmarks > iMac 21.5" Benchmarks (Intel)

Update Published April 7, 2026

Geekbench 2 through Geekbench 6 benchmark averages for all compatible iMac models with a 21.5-Inch display are listed below (2009-2021). All 21.5-Inch iMac models have Intel processors.

EveryMac.com diligently has hand compiled -- and independently averaged -- these Geekbench benchmarks from aggregate user results submitted to Primate Labs for each 21.5-Inch Intel iMac. This data is unique to the EveryMac.com website.

Generally, EveryMac.com has calculated averages within a few weeks of the release of each new Mac. Via a combination of our own custom algorithm for automated analysis and manual human review, benchmark results that are significant outliers, inaccurately tagged, not running the macOS, or otherwise errant are omitted prior to calculating an average. For many models, EveryMac.com runs Geekbench software directly on one or more devices, too.

On 21.5-Inch Intel iMac models, the Geekbench 2 benchmark provides 32-bit and 64-bit performance using all processor cores; the Geekbench 3 benchmark provides 32-bit and 64-bit performance each with a single processor core and all processor cores; and the Geekbench 4, Geekbench 5, and Geekbench 6 benchmarks provide 64-bit performance with a single processor core and all processor cores. Higher numbers are better. Geekbench benchmarks cannot be compared across versions.

Geekbench benchmarks also are provided on EveryMac.com's specs pages for all 21.5-Inch Intel iMac models and within the Ultimate Mac Comparison feature.
