Hello fellow bitcoiners, I was going to post this in another thread, but I think it's best to make a new post. One of the biggest costs in running mining equipment is going to be power consumption. 1Gh/w is far and away the BEST offer in this area thus far. We've had others offer estimates so far, and to be fair, these are all estimates until the equipment is running in the hands of the community. - BFL - 1 watt/Gh +- 10% source
- Avalon - 2-6 watts/Gh source
- ASICMINER - 4.2 watts/Gh source
- bASIC -2w/Gh source
- DeepBit "Reclaimer" -???/Gh
Avalon seems to be unsure of their power usage, thus the wide range. ASICMINER seems pretty sure of their wattage estimates which are 10x more than BFL! I'm not sure about you guys, but 6x the power consumption when you start running any sizable amount of equipment is HUGE. If there is more info out there that I have not seen, leave a reply and I'll add it in. Best, gigavps

Having already ordered a jalapeno, I'd say im pretty happy that the power usage will be so low. If I can run this straight from the usb ports on my raspberry pi, I will be very happy.
If these generate a considerable amount of heat, I might even use it to warm my little sisters hermit crab tank, and heaters like that use around the same amount of power.
I just wonder when the new "little SC's" will be available, I might purchase one if I can somehow use my jalapeno order towards the price. Its cool to see all these asics popping up, I wonder what kind of miners will come up next? Huge supercooled quantum miners?

yay competition , we should including pricing estimates as well though so we can have the full picture.

- ASICMINER - 10.64watts/Gh source
Final specs have been revised. 4.2W / - revised hashrate has not been published. Assumed to be around .5-.7 GH.

If I have missed any information though, please let me know. Hopefully other manufacturers will be able to give estimates with as much certainty as BFL.

OP has been updated. https://bitcointalk.org/index.php?topic=91173.msg1211518#msg1211518power spec is given as J/GH not W/GH/s. The reason is that chip GH/s performance is rather irrelevant due to minimal hardware costs.

Looked over the source again. Seems to have been updated to 4.2J/GH. Should clear that up.

Joule is energy, Watt is power. 1 joule = 1 watt-second.

Most heat generated in electric appliances, electronics and computer gear is caused by inefficient use of electricity. For example a 100 Watt bulb is drawing 100 watts, but not all 100 watts is going into the creation of light, a lot of it is wasted in heat, and that's why the bulbs get so hot. Same thing with your CPU or GPU. The heat is just electricity that's not being used efficiently, so it gets converted to heat. I'm guessing the ASIC's must be pretty efficient, but even if you look at the worst case of 100% heat loss, you're only look at a 4.5 watt or 60 watt heater. I'd be shocked if even the SC puts off more heat than a single GPU, and even then, that's a stretch.

So, if that's the case, you're not looking at a huge amount of heat at all. Your normal hair dryer is like 1875 watts.

Hi Dust, I think is is fair to say that it is not clear what Tom is saying there. I would rather wait for him to announce the info and then we can add it to the list. Best, gigavps

Best, gigavps Tom said exactly in the above comment "[the 27Gh/s device] uses less electricity than the ModMiner Quad", so it is pretty clear to me that it means less than 40Watt. Hence 675 Mhash/Joule, or 1.48 J/Ghash. Now if you wanted to be pointy, one could say that Tom did not promise the 54Gh/s device would have the same efficiency as the 27Gh/s one...
