In this video, I compare the performance difference between CPU rendering and GPU rendering within Blender. I am running a 6600K i5 CPU and SLI GTX 980 graphics cards. However, you’ll see in the video that I break it down to the single core performance for comparison.

NOTE: Although I mention that in MOST cases, the GPU will render faster, there are some setups that would allow the CPU to be faster. For example, if you are running an old GTX250 vs dual XEON CPUs, the Xeon’s would probably win, but if both components are comparable, I’d bet on the GPU. My research showed that even a GTX 650 Ti card could beat an i7 6700K!
