Increasing the bus width doesn’t necessarily increase processor speed. What matters is that the amount of data the bus can transfer to or from the CPU in a given amount of time is well matched and synchronized to the amount of data the CPU can process in that same unit time, or as closely to it as practical.Click to see full answer. Hereof, how can bus bandwidth affect processor speed?The speed of the bus, measured in megahertz (MHz), refers to how much data can move across the bus simultaneously. FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer’s performance. what is the benefit of having a larger bus width? A higher Bus width allows for the transfer of more data per LOAD operation. In theory, a 256-bit GPU can access 4x as much data as a 64-bit CPU in a single LOAD operation (hence, why CPU’s tend to be clocked higher, to allow for more LOAD operations to compensate for a small data bus). Also Know, what is the effect of the bus width on the speed of a computer? If you have a larger bus width, as with a system clock, the commands can be processed quicker. Clock speeds affects that performance of a computer system by: if the frequency of the clock period is higher, then the speed of the processes within the computer will also speed up.What happens when you increase the width of the address bus?By increasing the width of the address bus, more memory locations can be directly addressed. Each time the width is increased by one wire, the address capacity is doubled. ARM processors normally have 32-bit wide address buses. A 32-bit ARM processor could address up to 232 = 4,294,967,296 memory locations!
