Amount of cache memory, speed of processor, speed of the front side bus
bus speed is a speed measured in megahertz that is detemines how fast the memory and cpu runs. high-quality memory is required for higher bus speed
size of the address bus
The CPU and the Motherboard bus(called the Frontside Bus) run at 2 different speeds. The Frontside bus runs at the speed that was specified for that particular motherboard and is powered by a crystal that sends electronic pulses over the bus at a steady rate. For instance you're bus speed may be 100MHz. But your CPU speed may be 800Mhz. The reason is that the CPU manufactorer build in a multiplier into the CPU to make it faster. In the example I just gave you, the multiplier is 8x. So 100MHz bus speed times 8 = 800MHz CPU speed. Now if you want to figure out the throughput you multiply the CPU speed (800MHz by 8(8 byes). And you have the throughput of 1600MB or 1.6GHZ. If you bought a PC with these calculations it would be a PC1600. Finally, the reason it is 8 bytes is because motherboard bus these days send data in 64-bit chunks which is 8 bytes.
That would be 1 GHz, though I would not want to attach a CPU of the speed to a bus that fast.
I don't know look on google
The front side bus connects the CPU on the motherboard to the Northbridge. Front side bus speed is in preference to how much data can move across the bus simultaneously, and is measured in megahertz.
The system bus is usually inside of the CPU, but I guess it depends on the processor and the motherboard. Usually, CPU clock speeds are faster, as they are measured in GHz, while the system bus speed is usually measured in MHz. Hope this helped! SeanHolshouser
CPU front side bus RAM clock rate
to conserve the battery life by reducing the bus speed between the CPU and RAM
motherboard and cpu
Your data busses sends information from component to component i.e. your FSB (front side bus)/system bus/internal bus communicates between your CPU and RAM, the faster it runs, the faster information is moved between your RAM and CPU giving your CPU quicker access to that data.
