如何选择CPU和GPU进行公平比较？ [英] How do I choose a CPU and a GPU for a fair comparison?

问题描述

我需要做一个有说服力的论据，一个好的GPU对于需要做某些计算的人可能是有价值的，并且可能愿意写他/她自己的代码来做这些计算。我编写了CUDA代码，使用GPU快速进行计算，我想将其计算时间与只使用CPU的版本进行比较。困难的部分是争论，我正在做一个相当公平的比较，即使我不是比较苹果和苹果。

I need to make a persuasive argument that a good GPU would be valuable to someone who needs to do certain calculations and may be willing to write his/her own code to do those calculations. I have written CUDA code to do the calculations quickly with a GPU, and I want to compare its computation time to that of a version adapted to use only a CPU. The difficult part is to argue that I am making a reasonably fair comparison even though I am not comparing apples to apples.

如果我没有办法声称我选择的CPU和GPU在一些有意义的意义上是相当的质量，那么可以说，我可能会故意选择一个好的GPU和坏的CPU。我如何选择CPU和GPU，以使比较似乎合理？我最好的想法是选择一个成本大约相同的钱的CPU和GPU;是否有更好的方法？

If I do not have a way to claim that the CPU and GPU that I have chosen are of comparable quality in some meaningful sense, then it could be argued that I might as well have deliberately chosen a good GPU and a bad CPU. How can I choose the CPU and GPU so that the comparison seems reasonable? My best idea is to choose a CPU and GPU that cost about the same amount of money; is there a better way?

推荐答案

没有防弹比较方法。您可以比较具有类似价格的单位和/或在同一时间发布的单位。后者将显示在两种产品的给定时间的最先进的技术使GPU前进。

There isn't a bullet proof comparison method. You could compare units with similar price and/or units that were released around the same time. The latter would be to show that the state of the art technology at a given time in both products sets the GPU ahead.
