I posted pictures of the 6 PCI-E version months ago in the other ebang thread. I am actually going to do some amp clamp tests to get REAL power numbers today. I will post what I find so everyone can have an accurate idea of the efficiency.
i'm waiting for this date ...
i was chatting on Skype with EBIT E9 customer support ...
they Told me 780$+100$ for delivery in EU eBit E9 + psu + shipment.
i also ask why, with a 14nm chip, ASIC E9 is less efficient than the S9 with a 16nm chip ..
if i ask too is a problem of firmware optimization ..
but i have got no answer!
14/16nm for all intents and purposes are the same regarding efficiency. To date only Samsumg and Global Foundries (under license with Samsung) is producing 14nm chips and TSMC doing 16nm which is slightly easier to produce.. Intel and IBM don't count because they do not share their production fabs with outsiders.
As for comparing to the s9 -- same thing as comparing a s9 to the Avalons or BitFury rigs which both use 16nm chips or even to the T9 (same chip as s9): When used in the s9 and R4 miners the design was driven to be be "highest efficiency on the planet". It worked but at the expense of the miners often being unstable/unreliable because the chips are running at bare minimum core voltage (Vcore).
Same chip used in the s9/R4 is used in the T9 and so far no one has trouble with the T9. Why? Because Bitmain is using a higher Vcore which increases power usage but also make the chips more stable. Same for Avalons and BitFury and probaly EBang: Higher Vcore for more stability. Good choice to make.
