Xeon Phi 72 cores 288 threads

Anyone is using one of those to render? This new processor is like a gpu but without the VRAM limits? Thanks for the explanation. I found nothing on internet about this.

    You can get an awful lot of high-end GPUs for the price of one of those boxes. A little too rich for the tastes of most folks hereabouts, I'd guess.

  • I've noticed these types of server-grade chips often being used in online render farms; they seem perfect for software that do not yet support GPU rendering (like VUE for example).

    As for Daz, it would be an interesting test to see how it performs in Iray paired with the GPU. I don't, as of yet, know how effeciently Iray handles all those cores.

    Cannot imagine the complete cost of such a setup.

    Supports 384Gb of RAM on top of the 16Gb that comes with the processor. How much would that cost in graphics cards? The only GPUs I can think of that don't even come close cost around £5,000 at the cheapest.

    They're about the same price as the high end GPU's used in supercomputers.  Each core is much slower than the desktop cores that you've encountered.  It takes special coding to get good performance from them.

  • Based on the Wikipedia entry for Xeon Phi, I don't think this could be used for any commercial rendering solution currently available. You'd probably get better results hiring somebody to write a DAZ translator to something like V-ray, where you could send the scene to a commercial render farm. I've used them for Modo projects and the speed is incredible with either the Modo renderer or V-ray. If Iray weren't so convenient vs bringing scenes into an external program, I'd skip a big hardware investment and pay a buck or two per render through a farm.
