CPU vs GPU performance

Posted by Hemprasad Y. Badgujar on July 18, 2013


in the performance of GPUs and CPUs. This has to be quite a compromise since actual performance depends heavily on the suitability of the chip to a particular problem/algorithm among many other specifics. The simplest method is to plot theoretical peak performance over time; I chose to show it for single and double precision for NVIDIA GPUs and Intel CPUs.

In the past, I have used the graph in the CUDA C Programming Guide, but that is frequently out of date, I have no control of the formatting, I have to settle for a screenshot instead of vector output, and, until I did my own research, I wasn’t sure if it was biased.

Below is Michael Galloy attempt (click to enlarge).
