Mac Benchmarks > iMac 20" Benchmarks (Intel)
Update Published April 7, 2026
Geekbench 2 through Geekbench 6 benchmark averages for all compatible iMac models with a 20-Inch display and an Intel processor are listed below (2006-2012).
EveryMac.com diligently has hand compiled -- and independently averaged -- these Geekbench benchmarks from aggregate user results submitted to Primate Labs for each 20-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 20-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 20-Inch Intel iMac models and within the Ultimate Mac Comparison feature.
Click the triangle to open "Quick Specs" for basic info. Click the name or image for complete specs, configuration options, identification details, full benchmarks, global prices and more. You also can lookup Macs and Apple devices by specific identifiers.
Asterisks indicate that particularly important details are provided on the applicable specs page. Also note that configurations listed are the default or most common; many models have multiple options. Refer to the specs page for full details.
