Guys, i'm italian.
here, to build a gpu mining rig, whit 5 r9 280x for a 3.6 Mh/s, you pay about 2000 euro.
estimated consumption even undervolting cards, is about 1.4 Kw/h that costs about 5.00 euro/day
the Gridseed ASIC, if i right understand, have 5 chips even "usb device" and it can do about 300 Khash/s for a consumption of about 30V. so, 10 device that i read cost 1360$ (1000 euro) would get 3,0 Mhash/s for about 300V. power costs is about 1.10 euro/day

ASIC miner 1euro = 3 Khash/s + 1.10 euro power/day
GPU miner 1 euro =1.8 Khash/s + 5.00 euro power/day

assuming that 1Mh made 0.01 BTC day:
asic miner made 0.03 BTC/day that is 25.5$ (18.75 euro) - power (1.10 euro) total 17.65 euro/day net (time to autopay 57 days)
GPU miner made 0.036 BTC/day that is 30.6$ (22.50 euro) - power (5.00 euro) total 17.50 euro/day net (time to autopay 114 days)
not counting space problems, overheating, noise etc.

in Italy, Gridseed ASIC is much more profittable than any GPU for scrypt mining now.

(change EUR/USD 1.36)
(change BTC/USD 850.00)

This is the (unfortunate) misconception that came about with poor translation and horrible press from Gridseed. The cost for a single USB machine (which includes 6x 60kh/s units) is $82 + 6 x $65 = $472. So you're paying $472 for 360kh/s. The minimum order is 10 of *these*, not 10 single chips (unless I'm mistaken), making the total for 3.6MH/s of hashing power $4720.

Indeed, and it's 5 chips on each miner operating at between 300-360 total (not each).

As for power, it appears to be .44W per chip in LTC mode and 5.3W per chip in hybrid mode

Here is where the chip prices were first confirmed at about $65:

Development board: each 500 yuan
chip: 400 yuan per piece, per pack of 1600 yuan four chips
This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person.

And here is a link to the specs sheet of the chips

I'm interested to see what happens with these.
