Title: Butterfly Labs Single
Post by: doublebuffer on March 16, 2012, 01:09:27 AM
Does anyone actually have one? Do they really get 832 MH/s?  How come all the other dual-chip FPGA's only get around 400 MH/s?

I read the tread and ordered one about 1 hour after reading the tread. By the members it really does the MH/s. The only "problem" seems to be, that the company which produces it is new and quite unknown. You have to trust them. If $600 is an amount you would care too much about, then I would recommend to wait until you can be sure to really get one. On the other hand, some guys ordered a handful of them on their own risk and got their singles. So so itīs on you. If you live in EU, then you can add $88 for shipping, another 19% of vat, also add some 5% of taxes, and finally add some coins for the paypal exchange rate. Thats all together nearly $900.

Interesting.  Why is it's hash rate so much higher than all the other FPGA miners out there like Icarus?

So far we donīt know what exact kind of processor there is inside. But it draws 80 watts at work, I guess that the other FPGA-units draw significantly less. Even less in W/MHash. Just put together some more FPGAs and you will have same Hash-Rate at less wattage. But you also will have a higher price to pay, which makes the other solutions less interesting. Thats my understanding of it, for more data just search the treads.
