You are mistaken. Though Active Mining has no working silicon, the projected power efficiency is substantially lower than Bitfury (previous gen tech) and all of the current 28nm chips.
That's complete BS. You don't know the details.
Who are you anyway? You registered 3days ago and have only posted in ACtM thread. Are you Crumbs? Iceman? Pankkake? You freak.
Actually it's is fundamental engineering.
An FPGA hardcopy will always be less power efficient than custom silicon. Based on actual, real hardware in the field, any easic hardware will consume > KNC's 1.3 W/Gh/s.
FPGAs are obsolete in the world of custom silicon.
So what was your old name? Is that you VBS?
Jesus, you are trying to compare BMW to AUDI! Or even better, VOLKSWAGEN TO SKODA.
They all are very much of a muchness and all sell rather well. Similar specs, similar prices, similar profit.
This blinkered view of the industry does not allow for healthy competition. Who knows what these companies will be producing in 18 months, and who knows which of them will survive. This industry is set to continue indefinitely and for those who think that the fight has already been won or lost, they'd do well to open their eyes.
