Thanks Ed, that answers my question. I was thinking of buying a Xeon Phi 7120P for $799 but as you say if it's only folding at 300,000 PPD then an EVGA 1080 Ti is a 4x better deal.PS3EdOlkkola wrote:@wdethoma - responded to your PM.
I have the Intel Phi model 7210 running at 1.3 GHz, and is recognized by FAH as having 256 processors. I purchased the system completely built from a systems integrator, Colfax. It was roughly $5,500, has 108 GB of main memory, an SSD, large HTC hard disk, and is water cooled. There are at least two x16 PCIe interfaces. In reality, there are 64 physical cores (IIRC), but with hyper threading registers higher in FAH. It supports at new A7 AVX core. It runs Linux CentOS 7.x.
Performance wise, it runs best using 192 of the 256 cores and does about 300K ppd on most A7 projects. It's about equivalent to a GTX 980 at standard clock rates (no factory overclock). Needless to say, it's not a barn burner of performance. Another way to look at it: My Titan X pascal's put out over 4x the performance (1.2+ million ppd) for $1,200.
Just curious: What's your definition of "cheap"?Aurum wrote:Silly me I saw a cheap Phi and impulsively bought it. ...
