Are Intel Macs G5s?

Question

No. Apple in 1997 began using central processing units (CPUs) by IBM and Motorola known as G3 to follow the original PowerPC processors 601 through 604e (never officially nicknamed G2), and the 68k processors (never officially nicknamed G1) by IBM and Motorola respectively. The G4 and G5 models were made by Motorola and IBM respectively and were improvements on the original G3 design. Finally in 2006, Apple started using CPUs manufactured by Intel in the Core Solo and CoreDuo processors, and this have now increased to faster Core2Duo and Xeon processors by Intel. While not officially called G6s, these Intel processors are not G5s, and while the iMac from 2006 through the mid 2007 release look like on the outside as if they are identical to the G5s that preceded them, they are not G5s except in form factor. Similarly the PowerMac G5s which look similar to the Mac Pros are very different models, in addition to the Mac Pros have an extra optical drive bay. And the Intel Mac Minis have 4 USB ports on the back where the G4 Mac Minis have only 2. Other models are more obvious whether they are Intel such as the MacBook Pro, and the MacBook and the new Aluminum clad iMacs with black rears and picture frames of the displays which are also Intel and not G5s. To tell apart iMacs externally without turning them on, use this article as a guide:

and find out the equivalent EMC# on the base of the iMac.
