GN chip bringup - Power consumption: 0.14ua/MHz at 0.77volts at low speeds. That's 0.56W/GH/s. More tests happening now.
These twitter updates are great. Whoever at HF is doing these, thank you.
0.56W/GH/s does not sound very encouraging since they were advertising <0.5W/GH/s underclocked. Not sure at what speed they are testing at but it looks like consumption is +10% of what they were shooting for?
HashFast_CL is doing them, though I have no idea who that is. I asked them for W/GH/s and I'm glad that they put it up today. They said they should have details on max clock speed and thermals within the next 24 h
The W/GH/s is preliminary and will change when the chip runs at full speed.
I'm not doing the tweets. According to Amy, Simon is posting them. I've let them know they are a very popular improvement over forum updates and blog posts.
According the product page, HashFast is advertising
Power Consumption at the chip: less than 0.65 W/GH/s +/- 20%
Designed to be underclocked for greater efficiency, and overclocked for greater performance*
so I'm not sure where the " <0.5W/GH/s underclocked" claim came from.
