Do you realize how fast you were going?

How would you calculate the theoretical throughput of a bus?

A) Bus width x CPU clock speed

B) Installed RAM in bytes x bus clock speed

C) Bus width x bus clock speed

D) Installed RAM in bytes x CPU clock speed

E) Just look at the speedometer. Try to keep it under the limit next time.

The answer: C) Bus width x bus clock speed

The speed of a system bus is independent of any installed memory or individual processor speeds.
