I'm also very impressed by this. Not only that they managed to squeeze so much power efficiency, but also the size of the device.
Regarding efficiency: Do I understand correctly that 0.75 W/G puts the Prisma at the top in terms of efficiency among devices that are currently shipping?
Is there any other company currently shipping devices with efficiency equal or greater to 0.75 W/G?
Yes there are other
companies that are currently shipping devices with efficiency equal or better than 0.75W/G.
Not impressed, Bitmains s3+ is already 0.78 W at the wall and announced the S4 which should be even better (<== just my expectation; no real specs yet) although it should have come out last week.
But how long will it take Bitmain to ship? For what I hear, they are having problems shipping on time and are having hardware issues.
They already shipped 9 batches!
