Xeon Phi benchmarks

Postby dbz » Wed Jul 31, 2013 10:26 pm

For those who hadn't seen it yet, some benchmarks of the Xeon Phi.

About 2x bvh build performance of an 8-core Xeon(slide 37) and about 3.5x path tracing incoherent rays performance of an 8-core Xeon(slide 45).

The 'hybrid traversal' method that is mentioned in the slides looks interesting.

regarding the presentation they just compare against their own implementations.
we see 2x more rays/s for coherent transport on phi compared to embree 2 and 1.1-1.25x
for incoherent rays. phi compared to intels latest servers is in the range of 2x, so that a
dual socket server is around as fast as phi for middle-complex scenes.
