The PowerPC 750 (aka the G3)

The PowerPC 750—known to Apple users as the G3—is a design based heavily on the 603/603e. Its four-stage pipeline is the same as that of the 603/603e, and many of the features of its front end and back end will be familiar to you from our discussion of the older processor. Nonetheless, the 750 sports a few very powerful improvements over the 603e that make it faster than even the 604e, as you can see in Table 6-4.
