When evaluating CPU performance which feature do you need to consider?
Amount of cache memory, speed of processor, speed of the front side bus
What are bus speeds?
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
Which factor determines the speed of CPU?
size of the address bus
Why is it more important to describe the CPU and the motherboard bus using the term frequency rather then speed?
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.
What CPU speed designation is closest to 1066Mhz?
That would be 1 GHz, though I would not want to attach a CPU of the speed to a bus that fast.
What is the formula for calculating the CPU speed if the Bus speed is known?
I don't know look on google
What is front side bus speed?
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.
Is the system bus or the CPU faster?
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
What options have an effect on the speed of the communication between the CPU and RAM in a computer?
CPU front side bus RAM clock rate
Why do laptop computers use CPU throttling techniques?
to conserve the battery life by reducing the bus speed between the CPU and RAM
Components that must use the same front side bus speed?
motherboard and cpu
How does the system bus contribute to the overall system performance?
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.
