The middle 2010 iMac

The Intel-based iMac was announced at Macworld San Francisco on January 10, 2006 and began shipping immediately. The first Intel based iMacs used a Core Duo processor and came in an identical form factor to their predecessor. They were available for the same price (depending on country), but were, according to Apple, up to 2-3 times faster than the iMac G5. Later iMacs used Core 2 Duo processors, and the current revision comes in an aluminum and glass form factor similar to the iPhone.

The third iteration of the redesigned Intel iMac features 2nd generation Core iX series quad-core processors across the entire line, and a significant step up in graphics performance. As expected, iMac also gained Thunderbolt, the new high-speed I/O port providing up to 10Gb/s.

Rev. F

Overview

The Late 2009 iMacs represented their second major design update since switching to Intel processors. Apple's 16:10 displays had been replaced in favour of new 16:9 displays in 21.5″ and 27″ models. Almost every aspect of the iMac had seen an update, with better display technology, faster processor and a newer architecture on the 27″ model, more RAM slots and better graphics cards being part of the mix. A new multi-touch mouse called Magic Mouse was also bundled in with a wireless keyboard which was now standard. Despite all these enhancements, the iMac's high-end models were even cheaper than the previous generation.

Rev.E

Overview

After months of rumors and speculation, the iMac finally saw an update on March 3, 2009. Most of the specifications were only tweaked and models were reshuffled to include only a single 20″ and three 24″ models. The processor is identical to the Rev. D's processors but the 2.4 GHz model was removed. DDR3 RAM was included along with a doubling of standard RAM and increase in Hard Drive capacities. Finally, the graphics cards were changed, bring the weaker 9400M used in the MacBook family to the 20″ and low-end 24″ but the stronger GT 120, GT 130 and Radeon 4850 to the higher-end models.

Rev. D

Overview

The Revision D iMacs were released silently on April 28, 2008. The biggest change was the introduction of Intel's latest processors based on the Montevina platform which was officially scheduled for release in June 2008. Other changes included faster RAM, the inclusion of Bluetooth 2.1, a high-end graphics card option (8800 GTS with 512 MB GDDR3 memory), a price drop on the high-end model and 2 GB standard on the high-end 20″ and low-end 24″ model.

Rev. C

Overview

Introduced at a media event on August 7, 2007, the new iMac marked the first major redesign for an Intel-based Mac. The new aluminum and glass combination as well as the addition of FireWire 800 was designed to make the iMac appear to have more in common with Apple's professional product line. Glossy displays were introduced to the iMac line, which offer improved contrast but a more reflective surface.

Rev. B

Overview

The Revision B iMac re-introduced 64-bit processors to the iMac line. Apple decided to use the mobile variant of the Core 2 Duo (Merom), which offers slightly slower speeds in exchange for lower power consumption and lower heat output when compared to the desktop variant (Conroe). Maximum RAM was increased to 3 GB on all models except low-end 17″ iMac. Firewire 800 was also included on the new iMac, making it the first consumer Mac to feature Apple's high-speed port.

The Revision B also introduced a new high-definition 24″ model with a resolution of 1920×1200.

Rev. A

Overview

Announced at January 10, 2006, the new iMac was one of Apple's first Intel-based Macs. There were no design changes made so from the exterior it looks identical to the iMac G5, but there were some key differences inside. Its processor was dual-core unlike the iMac's G5, however it isn't 64-bit capable like the G5 in iMacs. Also the iMac G5 could include up to 2.5 GB of RAM whereas the Intel iMac only had support for 2 GBs. Despite these two shortcomings, Apple claimed the Intel iMac was several times faster than the G5s. However, as very few pieces of software were completely universal and dual-core aware at the time, the Intel iMac's performance would vary wildly between different applications.

On July 5, 2006, Apple introduced a new education-only model of the iMac. Priced at US $899, it was touted as a replacement to the eMac. It came in a 17″ form factor and was similar to the traditional 17″ model but had a smaller hard disk drive (80 GB), a Combo Drive rather than SuperDrive and a GMA 950 graphics card. Bluetooth and an Apple Remote were not included as standard.

Like all other Macs of the time, the extremely outdated AppleWorks suite was dropped as a standard feature to encourage iWork sales.
