Maybe ignorant question, but how are the ASICs going to work? I thought the whole point of DAGs was to prevent ASICs. How do the ASICs fit the DAG file on their chips affordably?
They don't ... they have DDR3 memory attached to the ASICs / FPGAs. If you look on the Bitmain site, you can see that the device is a) twice the size of their other miners and b) is about the hash equivalent of 4x 580's. If you consider the 800 watts of draw, it uses more Watts/MH than a rig with 4x 580s. About the only attractive thing about it is the price ... $800.
180 Mhash/sec is at least 6 RX 470/480/570/580 even with BIOS straps and all other optimizations. (widely reported in the 28-30 Mhash range for best optimized cards, sometimes a bit less).
It's also a HAIR less than 6 x GTX 1070 (31-32 Mhash common numbers, rarely under 31).
Power usage is pretty much a tossup with a well-optimized 6 card rig - bit higher than the Nvidia option, right around the same vs the AMD option.
The size IS interesting, and has led to some speculation that it's somehow a GPU rig - but the PRICE makes it unlikely to be GPU based.
