It was an Amdahl machine, it was their (Amdahl's) first machine capable of a Gigaflop. This was early 80s.
And it was not a single processor, it had many CPs. I don't remember exactly how many, my fuzzy recollection is that it was hundreds, not a few or a dozen. I don't remember them competing with anything Cray made.
I believe it used the same air-cooled processors, the 470, that was current in their mainframes at the time. The 470 was the competition for IBM 370 that ruled the world at that time. Air-cooling was a big deal, the IBM mainframes were water cooled and that added to expense and complexity.
