Personally I always thought the i860 was far from a

fact it was the highest MFlops/dollar and MFlops/watt for a considerable
length of time and used in a number of high-horsepower applications
in the real world.
And Intel sure sold quite a few i860s. I would bet that most i860s
ended up as coprocessor cards in PeeCees, where they did one task and
did not run into the dreaded pipeline flush context switch problem.
I know I've seen i860s in graphics boards. I think one of the NeXTs used
them as well.
I don't recall seeing any i860s in NeXT hardware. What was on the NeXTDimension
board? It has been too long since I've seen one.
Some high-end SGI graphics subsystems for their Ebus machines use big arrays of i860s.
