Guess I can answer this one as I was just curious (people from the 
luxrender project did claim a 60x speedup) and did implement a simple 
raytracer with a static scene and did follow Intel's recommendation of 
doing warmup runs before actually measuring the runtime. Here are the 
results for the raw calculation time without scene initialization:

CPU using 8 threads
fps 33.39695
2.9942 seconds

OpenCL CPU using 8 worker units
Intel(R) Core(TM) i7 CPU  950  @ 3.07GHz
2.8005 seconds

OpenCL GPU using 18 worker units
Cypress
1.7871 seconds
