MHz speed


Of what? External data bus (EDB)? Front-side bus (FSB)? Do memory bus has some sort of frequency rate also? Is EDB the same as FSB? "The inclusion of the L2 cache on the chip gave rise to some new terms to describe the connections between the CPU, MCC, RAM, and L2 cache. The address bus and external data bus (connecting the CPU, MCC, and RAM) were lumped into a single term called the frontside bus, and the connection between the CPU and the L2 cache became known as the backside bus (see Figure 4-29). (These terms don’t apply well to current computers, so they have fallen out of use. See the “Integrated Memory Controller” section, later in this chapter.)"
