Why is the SP20 less efficient than the SP35?
I thought they used the same ASICs?
SP20 1100W / 1700 GH/s = 0.65J/GH
SP35 3500W / 6000 GH/s = 0.58J/GH
It's also 35% more expensive per Gh/s too.
SP20: $1,190.00 + $300 PSU for 1.7 Th/s = 0.88 USD per Gh/s
SP35: $3,920.00 for 6Th/s = 0.65 USD per Gh/s
The above prices don't even include the $115 shipping fee. Face it, the SP20s are terribly priced. S3s and Tubes offer far better value.
