If you want pure speed, intel wins bigtime when you overclock it to the max.

But you need to be a little skilled for ovrrclocking.

At default speed, intel 3770k beats amd fx 8350.

Basing my conclusions on Cinebench raytracing benchmark, while it is not Carrara, it shoyld be very close.

Same results for povray 3.7.
