> Is this a typical performance profile for doing ray tracing in OpenGL? I expected tens of times faster than a CPU on commodity hardware.
SIMD instructions on modern CPUs are getting really good, within the ballpark of GPU speed in some cases. Here's the classic paper [1] on this, and the results have gotten even better since then with AVX2, etc.
