iTOP introduces the newest bitcoin miner The S5+ from bitmaintech, The S5+is the upgraded version of The S5, it uses The BM1384 chipset , S5+ brings totally new innovation designs for the cooling system , the hashrate of a sigle unit reach up to 7722G/s, powercosuming only 0.445w/GH, antminer S5+ is the highest hashrate and most optimal power/performance miner all over the world.
A Spondoolies SP20E can achieve the same efficiency as this unit claims, which is noticeably better that the S5.
The new Sfards unit can achieve even better by a bit, though the reliability of that unit is looking distinctly "early Gridseed".
Is there a reason you insist on selling these in a no-rack-mount configuration despite their rackmount unit sizing? Would make more sense to sell them as individual S5-sized units, NOT as triples.
The price is WAY too high to ever be able to ROI on the unit, unless the rate of difficulty increases drops to under half of this years "so far" rate, or bitcoin value kicks up a LOT.
The "cooling" design is a sad joke, the airflow is way too constricted and passes over WAY too many heatsinks to work worth anything for the last couple rows of chips in the air flow path. "push pull" fans do NOT double the airflow, the ONLY thing they do is reduce the back pressure allowing a SMALL flow rate increase.
These comments assume that the unit is actual, not just a good photoshop job scam or a picture of a prototype concept that is a REAL BAD IDEA at best.
just saw Bitmain confirm the unit is real, which doesn't affect my other comments.
0.45 efficiency is not enough to make this unit viable for a significant length of time IF AT ALL past the block reward halving next summer, any more than the S5.
If you wanted to make a unit that WAS viable past the halving, run 20 chips per chain not 16. That would unleash the REAL efficiency potential of the BM1384 and might actually rival the NEXT GEN units that are on the way from Bitmain and Innosilicon (I discount BitFury and KnC as neither sell to end users any more).
