They have emailed me saying that the Rig Box has additional performance improvements, being 32 clustered boards instead of 1 single, that enable it to reach 54 GH/s.
Does that make sense to you?
Do 32 GPU have 54x the performance of 1 GPU?
Do 32 CPU have 54x the perofrmance of 1 GPU?
If 1 board was capable of 1.7GH wouldn't it make sense to just apply those magical unicorn optimization and make the single board 1.7GH too. They could sell it for 70% more right? Unless 70% higher revenue per sale is a bad thing.
Yes it makes sense that 32 specialized boards can run together and achieve improvements you wouldn't otherwise get with a single board.
On a problem like SHA-256 hashing which is perfectly parallel? Really? Care to hypothesize how that works since you seem convinced.
SHA-256 is a perfectly parallel problem. A single hash takes only a billionth of a second. There is no need for boards to work together. No need for cores to even work together to solve a problem which takes a single clock cycle to solve. Each hash is independent of the others thus there is no need for cores to even know about each other.
So to make a cluster faster they aren't working together rather working simultaneously on the same problem. Like two, or 8, or 32 workers oblivious to the fact that others are also working on the same problem.
32 independent workers don't accomplish 54x the work of a single worker.
