The PowerPC 603 and 603e

While one team was putting the finishing touches on the 601, another team at IBM’s Sommerset Design Center in Austin had already begun working on the 601’s successor—the 603. The 603 was a significantly different design than the 601, so it was less of an evolutionary shift than it was a completely different processor. Table 6-2 summarizes the features of the PowerPC 603 and 603e.
