I was one of the Kickstarter backers for the Parallella a few years back. The 64 cores are in the Epiphany IV coprocessor, while the board itself has two ARM cores and would behave a lot like the RPi and similar if the Epiphany wasn't taken advantage of, assuming you were able to get your hands on one of the early 64-core boards. The 16-core Epiphany III-based Parallella is available at Amazon.
