ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382

[powersup]

Price is far better then I was expecting.  Bitmain shaking up the mining industry!

[oskuro]

Wow... great price point at 0.75BTC per unit.  The specs state you only need 2 of the 4 PCI-e connections if you want to run it non-overclocked - so it would appear I can replace my 2 S1s with these and use the same HX1050 to power them both.

and S3 overclocked how much GH/s would be? and power consume how much increase? (more less)

From the description:

Quiet: The customized heat sinks mounted to the hash boards, one box over S3 to control the air flow, two fans mounted on both front and back ends that mean fans are able to work at lower speed to dissipate all heat easily. This design let S3 run at much lower noise level.

Yep thats what it says, but on their website they posted the screenshot showing both fans running at 2850rpm.  That isn't quiet from my experience.

The S1 fans were PWM so ran at whatever speed was necessary to maintain the correct temperature. I expect the same is true for the S3, if your ambient is hot then the fans will run fast.

Ordering will be up shortly it appears, but shipping starts on the 10th of July.

[ernie-]

Ordering will be up shortly it appears, but shipping starts on the 10th of July.

That will mean after the next difficulty increase.

[oskuro]

and how many units do you think 1st batch will be? because i need 0.19 more BTC and maybe if i have a week... i can earn it, but if 1st batch orders end today in a few hours... i will have to wait till 2nd batch

You mean difficulty adjustment. To be fair right now its looking pretty stable. I wouldn't be so bold as to say it'll go down but even bitcoindifficulty.com is only predicting a 1% rise still.

I have a Silverstone Tek 500W(ST50F-ESG) that only has 1 PCI-E, question will I be able to use a MOLEX-to-PCI-E or SATA-to-PCI-E adapters? TIA.

order now. shipping will be between 10 and 20.7. (plus few days to deliver).. it could hit two diff. incr (2*20% ??) . .. means the price is like 1,08 BTC...if shipped now....

[Biffa]

So with +/- 5% we could be looking at as low as 454GH/s or as high as 501GH/s

Great, I can quote websites as well

16,818,461,371
Next difficulty (estimate): 16,940,141,261 (+1%)


I also note your link has already fallen to 19.9% just minutes after you linked its so it's correcting downwards.

[marah]

That's $1 per GH/s. Awesome!

[PatMan]

Bitmain - can you confirm that these have been tested & are working on p2pool?

Please.......?

[allcoinminer]

Not a great price. It should be lower. Need to wait for second batch.
Hope you guys checked the ROI after 15days.

I'd rather be pessimistic and pleasantly surprised.

You honestly think that with all the hardware being rolled out currently that we will see the lowest difficulty increase in since January 2013?

I think saying a 1% expected difficulty rise is a bit misleading.

[oskuro]

Not a great price. Hope you guys checked the ROI after 15days.

for me its a great prize considering:

S1 --> 200 GH/s overclocked --> 420 W from the wall
S3 --> 478 GH/s --> 366 W from the wall

i have right now 2 S1 with power consume of 840 for 400 GH/s so its a great difference of power cost

I agree 1% is misleading, but the early signs are that it won't be another 25%+

Do bear in mind that as difficulty ever-rises the amount of hardware that must be rolled out per change also goes up by the same amount and I don't believe asic manufacturers are ramping up that fast.

With the announced S3 date I actually think this might be a reasonably low difficulty increase, yes. There's a couple of ways of looking at this, depending how tin-foil-hat you are;

1) the S3s are already running ('testing') and have therefore already contributed to the hashrate, and will sit there doing so until the 10th of July. Result, no difficulty increase of significant magnitude from available bitmain products, because who would buy an S2 now.

2) the S3s are being built by the bucketload ready for shipping, but will not do so until the 10th of July, not arriving with customers until the 12th/13th, around the time of the next difficulty change. Result, no difficulty increase of significant magnitude from available bitmain products, because who would buy an S2 now.

1000$ would be too high, 1-1.2 Btc would be fair at this market.

That is just some guy who sells his gear on amazon, and he speculates on the price, or am i missing something?

Honestly, I do not know. It says by Bitmain... On the other hand, why would he post first on amazon....

FundaMiner is the seller of that gear.  He just listed it put long shipping time.  Will take your 1000 buy the miner when it drops on the bitmaintech site and pocket what he hope is 200 or more dollars
