The production units that we have assembled and tested so far are running at between 1.63TH/s and 1.72TH/s with power draw at the wall between 1900W and 2100W typically 20% higher than our anticipated target of 1650W
20%??? What happened to:
The chip will consume less than 300w, for a performance of 504 Gh/s.
Sounds like you missed the power target by quite a bit more than 20%.
they didnt say what their asics draw. they said what the system draws at the wall.. which includes a built in controller, plenty of fans, a liquid cooling system (pumps). and they confirmed that their power conversion circuitry is what theyre redesigning for the new version...
anyway... what any asic company says (based on simulation) before they get their chips back, and what they say (when its fully tested and includes all the real-world losses) after their chips are in a system always seem to be different.. and i cant think of anyone who delivered a system with the same power draw as their specs. can you?
