Brief
ASICMiner Prisma is based on a proprietary X48 design for BE200. It greatly reduces power
consumption of the device per GH/s compared to the X24 design.
...
Power consumption: ~0.67 W/G board-wise. On-wall power consumption relies on PSU
efficiency. (typically 1050-1100 W per full device, 0.75-0.78 W/G)
Nice. I wonder how they managed to squeeze improve power efficiency by ~25% compared to the X24 design.
But even though this further destroys the mining competition, it probably requires nerves of steel to continue investing in miners at this time.
