Xeon Phi hardware is starting to trickle into used markets for… affordable?.. prices.
As with any Intel processor, they are compatible with OpenCL, meaning that, at least hypothetically, they would work with Blender and other render programs. I’m looking at this as a possible render accelerator that does all of the things that GPU rendering can’t do.
Intel’s website is surprisingly uninformative about Phi. Does anyone here know anything vis-a-vis Blender?
