I have heard of this before and was rather excited to see further developments. But am I reading this right? The stochastic processor is 70x slower than a conventional processor. The only reason they achieve 3x faster is due to "parallel" processing? The details are vague, but does the speedup have anything to do with the fact that the processor is non-deterministic?
