Now there’s a name I haven’t heard in a long time.
And the Xeon Phi (Knight’s Ferry/Landing) was in the GPU space, but only in GPGPU. The idea was that the Xeon Phi, with an x86-compatible core, could, with less modification, run software that was originally targeted to a standard x86 CPU. Something like 68-70 x86-64 cores.
I had a couple of them when I was taking parallel programming back in the day. Nifty little devices, but largely outshined by distributed multiprocessing for x86-64 and paled in comparison to the power of CUDA. That might be my own bias talking though.
I don't have personal experience, but AFAIK that's what everybody says. They were marketed as compute units, but their compute performance was very poor compared to the competition.
