View Full Version : Hybrid or GPU?

07-29-2013, 06:08 PM
hi guys,

i have an i7 1366 (first generation) oc to 3.8GHz, and a GTX 670 (and 12GB DDR3).

i want to take maximum benefit from my HW, and seems logical enough to me that the render would benefit from the additional workload the CPU provides; on the other hand, is the CPU slowing down the GPU? usually i see from task manager the CPU on an average 75-80%

what would you advise?

do some calculations of how fast your cpu is vs how fast your GPU is. You'll find the cpu barely touches the speed of the GPU once you mutliply by the number of cores. The reason it may be slower is it's taking more time to translate and combine the two than it does to just render it on one.
You have an old processor and a relatively new GPU. The advice is to render with just GPU, get a second GPU if you want more speed, or get a new computer with a current processor.
