The market for discrete workstation GPUs is relatively small though as most firms upgrade the complete system. Figures by Jon Peddie Research reveal 1.28 million workstation-class GPUs shipped in Q3 2014 while 1.02 million workstations were shipped in the same quarter. And it's safe to assume that at least a small portion of these workstations contain more than one GPU.
AMD claims its pre-rebate pricing already allows it to be a performance-per-dollar leader in almost all price segments, but whether that leadership holds after factoring in running costs, performance per-dollar-per-watt, is another matter. That point is especially poignant given that some of Nvidia’s newest Quadro GPUs make use of the highly-efficient Maxwell architecture that current 28nm GCN designs from AMD cannot match.Source: Hexus
