After looking around the web for a while, I've gathered that GPU rendering in Blender is supposed to be much faster than CPU rendering, but on my machine, the CPU is actually slightly faster? My GPU is a GTX 1070ti with a 200mhz OC and my CPU is an i5-8400. Rendering a simple image takes around 45 seconds on the CPU and 50 seconds on the GPU even with the 200mhz OC. Is there something I messed up in the settings? Or is it supposed to be like this?
