Title: BITMAIN's BM1380 chip is open for ordering. 10,000 chips for 99.9BTC Post by: BITMAIN on December 09, 2013, 07:13:11 AM Summary
BM1380 is a Bitcoin mining chip developed by Bitmain, a Chinese based IC company. We use the chip to build S1 Dual Blades, nearly a thousand of which has been sold to the Bitcoin community. BM1380 can run at different mode, depending on the favorite of the users. It can run at 0.75V core voltage and 0.68J/GH high efficiency which can compete with some 28nm mining chips. At 0.75V the hashing board runs without a heat sink. BM1380 is also running at 1.1V or 1.25V voltage sounding reliably, doubling the hash rate and the efficiency spec still better than most of other 55nm node chips on the market. Now the chip is open for purchase. About the Chip Process Node: 55nm Number of Cores: 8 Package Type: QFN56 Packaged Chip Size: 8 mm x 8 mm Rated Hash Rate: 2.8GH/s @ 1.1V
Every chip will be tested as qualified before shipping out. Price There are 10,000 chips in a single lot. Now the price is 99.9 BTC per lot. Every lot has 32 extra chips for testing, shipping within 3 days after purchasing. Open Source We are going to open the entire designing documents and bin file for designing and produce the S1 Dual Blades hardware. For some complicated parts, we may provide some parts of the miner at our cost. We will sell control board at cost for chip buyers. We will upload the the reference design in a few days, to https://github.com/AntMiner Lead Time Lead time is around six to seven weeks. We promise lead time to each customer before making payment. 1. The wafers have been ordered already and under fabrication before we open sale. 2. We also reserve safety chip stock to hedge potential delaying risk and guarantee our delivering promise. 3. We promise every chip buyer a delivering date, which will be accurately planned. Large orders will not be able to deliver in a single day, but we will commit a period before buyers making payment. Support With our open sourced document, we think a qualified hardware engineer will be able to build a miner or even design an improved version without any support. However, we know that many chip buyers are financial back grounded and it is very likely that their hardware engineers are contracted, and not fully devoted into this. To move things faster, they may need help. We do want to provide support to our chip buyers, while we have very limited human resources. And we are all not native English speakers, so supporting global customers will cost us even more time. So we are now encouraging technicians and hardware engineers in this community to stand out, and read into our document, and provide help when our chip buyers has any trouble in building a miner. This is how this mechanism working out: 1. If you are a hardware engineer who is interested, please read into our open sourced documents, decide whether you can handle all the problems. We hope you have the experience and resources to handle the production management locally. 2. Stand out in this board, announce your language skill, location and back ground, so our chip buyer may find you. We will list you in our official store when it is put up. 3. All chip buyers has a 2% supporting budget. It means that a chip buyer can tell us who has helped him out, and you will get this budget. How to order: Please fill this form, and we will send you the payment address and a promised shipping date. via info@bitmaintech.com https://docs.google.com/forms/d/1dhozMBbO6ZsM_kT4Nf5tQD-qi3oh7JXOhTlh5RSyKcc/viewform Please write down and check the PIN, so you know it is BITMAIN who send you the email.

Is it? Are there any tech docs available. If it is Avalon 2 (even it is not) The price is too high in my opinion. Two months to market at least for minig borads to be assembled My feelings tell me that it is Avalon2 for sure...But anyway time will tell Good luck to you and your customers Title: Re: BITMAIN's BM1380 chip is open for ordering. 10,000 chips for 99.9BTC Post by: goxed on December 09, 2013, 08:04:49 AM Seems Like Avalon2 Chip?

+1 group buy Title: Re: BITMAIN's BM1380 chip is open for ordering. 10,000 chips for 99.9BTC Post by: bobsag3 on December 09, 2013, 08:33:06 AM I would appreciate a response to one of the 5 emails, and or PMs I have sent regarding this.
Title: Re: BITMAIN's BM1380 chip is open for ordering. 10,000 chips for 99.9BTC Post by: loshia on December 09, 2013, 09:26:05 AM I know how much hate is accumulated against Avalon team. I am not advocating for them here but so far they get delivered their AVALON2 chips without any delays from stock according to this forum. But what i can tell you is that:
Avalon batch 2 chips are available for immediate delivery at 6 btc per 500 chips - 20% above compared to this offer with almost 13 times less investment. And they get delivered in day or two. There is a reference design for Avalon 2 + technobit and probably others with working product so time to market for ready to mine products will be 10 - 15 days max (if all is going well without delays) compared to 2-3 months with this chips So Profit (IF ANY AT ALL) will be bigger with avalon2 compared to this offer For me this chip at that price of 100 Btc with unclear feature is looser definitely. Luck to all of you.

Luck to all of you. Best BM1380 can hash at 2.8GH/s, 86% faster than an Avalon2, and consume much less power(1.3J/GH vs 2.5J/GH), which will lower the cost for AC/DC power supply and DC/DC module.

It remembers me the days when i got my AVALON batch 1 unit. And BFL folks who still are waiting for their orders were crying we will blast you away because of the power. It turned out that with just a day of mining i paid for the electricity for whole year. What i am tiring to say what matters most is time to market for me. But this whole story is leading us to nowhere just spending money FOR NOTHING and that is all I wish you luck with this power efficiency after 3 mounts. all the goup buys drama, the technical delays which are going to happen for sure, the chinese new year and good knows what else Best I am not mentioning the fact that " the cost for AC/DC power supply and DC/DC module" is the last thing one should be thinking of compared to highly overpriced ASICS themselves spending a bug or two even ten for Power supply is an miserable expense Title: Re: BITMAIN's BM1380 chip is open for ordering. 10,000 chips for 99.9BTC Post by: BITMAIN on December 09, 2013, 10:17:08 AM It is a shame that some Avalon shills come to this thread with misleading statement on the chip performance and price comparsion. We just lock this and open another self moderated.
