So, I'm looking to upgrade some old at-home miners, and i saw this flu miner that just came out. It is marketed as highly efficient.

It's almost 3 grand for 6 GH/s, but it eats 1700w of power. I have a an avalon q, which eats 1800+ watts at high power and gets 90 TH/s. Isn't that better? I thought it went from kilo -> mega -> giga -> tera. So, what am I missing here? How is the flu more efficient?

The fluminer is marketed as efficient, but if I am getting an order of magnitude less hashes for only 100 w savings, that doesn't seem efficient. I see that it uses the Scrypt algorithm, but does that really make that much of a difference than the SHA-256?

I pool mine with the unmineable pool, so it would seem more hashes = more coin.
