What is the clock speed of a computer?
The term “clock speed” is usually short for “core clock speed” and it is how rapidly the CPU’s core clock runs. The core clock controls the timing of instructions executed by the CPU. All other things being equal, a computer with a higher core clock will execute more instructions per second than one with a lower core clock. Note that all other things are almost never equal though. So it’s very dangerous to compare core clock speeds without looking at other factors. For example, a 2.66GHz Core 2 Duo will beat the pants off a 3.06GHz Pentium 4. While the Pentium 4’s core clock runs faster, the Core 2 Duo needs far fewer clock cycles to get the same work done. Because modern CPUs execute more than one instruction at a time, take variable numbers of clock cycles to complete different kinds of instructions, and have varying numbers of cores and execution units, comparing core clock speeds is even less useful now than ever before. And, of course, it doesn’t much matter how fast the core cloc
