This question is from my e-commerce class. I'm having a hard time trying to find the answer (I know nothing about computer hardware) - "Assuming that you have two processors of the same architecture, why might you want to use one with a higher frequency?" (I'm assuming that "processors" referred to the processors inside a CPU?).

I have a feeling the question is asking if you had two processors and you could only put one in the computer, why would you want to use the one with the higher frequency.

As the the answer, the higher the frequency the faster the processor will execute instructions. For example a 1.8GHz processor will be slower than a 2.4GHz processor. However the question is kind of out dated, before around 2005, processor frequency is that all really mattered which is why it spiked close to 4GHz. However now days the focus is on getting the most performance with the least amount of power used. So for example a 2.4GHz Core 2 Duo processor will be faster than a 3.0GHz Pentium 4. The reason for this is that they've made how the processor works better, and having more cores inside the processor at a lower frequency makes the processor able to do much more at a slower speed.

The qualification in the homework question of "two processors of the same architecture" makes it easier than this, though, so the first part of the answer hits it correctly.

A C2D processor and a P4 are the same architecture though, they both implement the Intel x86 architecture. They are however, different processor families; unless the question is misusing the word architecture to mean family.

In that case, I'm guessing it's a technical misuse of terminology since it's a question for an e-commerce class rather than a CS-related architecture class or something from an engineering curriculum.

Thanks, guys!
