Intel Processor Power

GainSaver’s huge inventory of professionally refurbished 21-inch iMacs are available in a range of processor types and speeds. They have powerful Intel processors, from Core 2 Duo processors up to models running on blazing fast Quad Core i7 processors. The refurbished 21-inch iMac desktops are the best choice for high performance with a mid-size screen. The only faster all-in-one desktops are the pre-owned Apple 27-inch iMacs. So if you don't need that large of a screen, then the Apple iMac 21-inch desktop is your best option.

 Filter by Processor Type

Used cheap 21-inch iMacs from GainSaver come a range of processor types and speeds.

Intel processors in the used 21-inch iMac come with either two or four cores. Processor cores are essentially individual processors within the same processor. Most software applications are capable of using multiple cores at the same time. The instructions that run the program are split up into multiple streams that are handled in unison by each core. More cores mean faster applications and better performance in everything from starting up your iMac to calculating spreadsheets, running filters on image manipulation programs and managing background applications by the operating system.

The slowest of the 21-inch iMac processors is the Intel Core 2 Duo. The next step up in performance are the Dual Core i3 and Dual Core i5 processors. With their improved architecture, the Dual Core i3 and Dual Core i5 are significantly faster even though they still have the same number of cores.

The fastest processors for the refurbished 21-inch iMac are the Quad Core i5 and Quad Core i7. They provide four separate cores for handling instructions. If you are doing processor intensive work like graphics, audio and video production, you’ll be happier with the Quad Core refurbished iMacs.

When comparing processors, you should use speed as a consideration only when comparing processors of the same type. A Dual Core i5 is much faster than a Core 2 Duo processor with a faster speed. One other factor to remember is that refurbished 21-inch iMacs that were introduced more recently are faster than older ones with the same processor type. Each year new iMacs are introduced, there are hardware updates that improve performance. So, to find the best cost/performance benefits, more recently introduced 21-inch iMacs with more processor cores deliver the most power.
