THELOGICALINDIAN - Bitmain afresh appear the Antminer S7 specs application their new BM1385 ASIC This footfall is a big one as the S7 is aircraft to anyone about the apple from baby home miners to ample abstracts centers Many added manufacturers are alone application inhouse or for the assertive ample mining operations that accept appear new chips Afresh we interviewed Jihan Wu cofounder of Bitmain After the account Jihan beatific aBitmain Antminer S7 to analysis The miner is an accomplished footfall up from accepted offerings on the bazaar Lets attending at the specifications

Disclosure: Antminer S7 was provided by Bitmain for review.
The S7 accustomed fast and with no damage. The Antminer S7 is congenital absolutely with a bifold push-pull fan system. The S7 is almost the aforementioned admeasurement as the S5 and packs a lot of ability in a baby package. The apartment has a new aberration to it, in that you can affix 3 of them calm at the abandon with a argot and canal system. I say three of them, as anniversary ambassador has the access to run three S7s at the aforementioned time. This stacking advantage will acquiesce for several altered means to arrange them. We were clumsy to analysis how abounding at a time the ambassador will run as at this time we alone accept the one S7. Being able to assemblage them calm alike if you are not application one ambassador for assorted units is a plus. It can accomplish for added defended arrange in your racks and shelving.
Antminer S7, Powerful Hashing With Lower Power Consumption
The ability burning to th/s arrangement of the S7 shines. While the S5 produced 1.155 th/s at 600 watts, the Antminer S7 is bearing 4.9 th/s application 1250 watts with a banal freq of 600. For this review, we acclimated two EVGA Supernova 1300 watt Gold rated PSUs. We will be accomplishing a video audience of the assemblage with the Bitmain 1600 watt PSU shortly.
The ability affiliation bureaucracy is a bit altered than you are acclimated to seeing on Antminers. The beefier ambassador requires a PCIe affiliation to augment it power. Each hashing lath requires all three plugs affiliated and uses almost 405 watts. What we did for this analysis was affix two of them to one PSU. Then affiliated the 3rd lath and the ambassador to the added PSU. It is important to bethink alone to affix one PSU to a hashing board. Do not mix assorted PSUs on the aforementioned board. Also of agenda is to ability on the PSU that does not ability the ambassador first. This adjustment will beggarly the hashing boards are powering up aboriginal for the ambassador to ascertain back you ability on that PSU last.
When the Antminer S7 is running, the babble is beneath than accepted for a bifold fan assemblage that is accepting to blow the calefaction generated in such a baby package. Bitmain did a acceptable of bond admirers that are aerial CFM yet not agreeable loud. The S7 is louder than the S5, but not as loud as the S5 . At 4 feet, it registers 66 dB. Most of the babble sounds like hasty air. There is no aerial pitched whine. While this may not be article you appetite to put in your active room, but it won’t drive you out of your barn either.
0.25 J/GH on a 28nm Die
Bitmain’s simple to use software is on the ambassador with the accepted firmware adaptation actuality anachronous August 29th. We did not acquisition any bugs or glitches as we sometimes acquisition that some miners accept back we get them afore the accepted public. The freq alternative is set up artlessly and offers lots of options, so overclocking and downclocking is simple to do.
The BM1385 ASIC is congenital application the 28nm process. In conversations with Jihan, he has declared that the 28nm action can be added optimized and with 28nm actuality a complete tech chips can be produced faster and cheaper while accouterment assets in performance. This achievement accretion is actual accessible with the BM1385 ASIC as the ability to gh/s arrangement at 0.25 J/GH is actual aggressive. The beyond die admeasurement allows for a greater apparent for calefaction amusement as well. These things add up to an S7 that has a baby anatomy agency and solid performance.
The Antminer S7 is a solid assuming Bitcoin ASIC miner that is actuality awash to anyone. The accustomed anatomy agency that Bitmain debuted with the S1 is there. Adding the tweaks of the argot and canal arrangement on the anatomy acceptance for easier stacking accompanying with a able-bodied ambassador acquiesce for new options for deployment. The achievement is the best on the bazaar appropriate now that you can get your easily on for Bitcoin ASIC miners. Bitmain has declared they will activate aircraft the aftermost anniversary of Sept to the aboriginal anniversary or so of Oct for accumulation one. From how the assemblage we accustomed for analysis works they accept the action bottomward and things attending acceptable for their aircraft window.
The Antminer S7 is a solid miner that will fit in able-bodied from baby to ample installations. The affluence of use that is one of Bitmain’s hallmarks is there as well. The S7 on banal ambience is putting out a reliable 4.9 th/s beyond Antpool, and Kano.is while affairs 1250 watts. It is a top aerialist like the S5 afore it. The Bitcoin block accolade halving will be accident at the end of July 2016 so accepting your easily on the best able miners you can appropriate now is crucial. The S7 is a abundant option.
