a hash rate greater than 0.5TH at a power consumption of significantly less than 1 watt/GH.
That sounds like 600TH/s with 300W power consumption.
Very hard to believe.
You have your G and T mixed up.
I meant GH/s, but I still find it hard to believe for a 600GH/s device to consume like 300W
It is all marketing of the words "greater" and "significant". 520 GH/s @ 480W would meet the "definition". That is why I pointed out there is no spec. Lots of range in words like "greater" and "significant". Significant to who. Some would say 10% better than anyone else is significant (and it probably is in the long run). You have obviously taken significant to mean 2x better which it probably isn't.
