They just announced T9 miner (11.5th/s) with less efficiency at 0.126 J/h+7% https://bitcointalk.org/index.php?topic=1755286.0similar setup to early s7 and late s7 (less chips, less efficiency); here they separated S9 and T9 (less chips, less efficiency). Good for those who has functional S9-those will be sold with some premium from now on. |

i think they figure the reason of high S9 hashboard failure
it's the power needed for the chips!
so they produced T9 with 180 days warranty
each T9 board have 57 chips instead of 63 and need 480W to power instead of 400W
less chips more power!

Interesting move on the T9. I wonder if its appearance is related to the recent steep rise in difficulty.

They were due to either release more S9's or something like this. Doesn't matter too much as they're close in efficiency. |

Remember the T9 is cheaper by ~$100 too. |

With t9 at 1450w it is going to use 90% of the bitmain 1600 psu capacity.
Should be 80% for safety.

Well if you find cheap used S9's buy em up, else if you have slightly cheaper electricity go for a T9. Really your choice here, I'd personally go with the S9 as there is no proof of better workmanship on the miner or better underclocking of their chip as of yet on the T9. I'd hold off on the miner until reviews get to the forum. |

I went for a r4 7.5 today
with power savings I think it is a better deal then the t9

Doesn't look like they over-priced it does it? I wouldn't expect a lower price on the next batch of the T9 if it sells this well. |

The T9 employs the same 16nm ASIC chip as the Antminer S9 and this T9 batch can deliver a hashrate of 11.5TH/s with an efficiency of 0.126J/GH (+7%).
Additional stock available at MOD EDIT: Suspicious fake link removed after 2300 hours (GMT+8) today (17 January 2017).
We advise all to place your order while stock lasts.

Happy mining,
The Bitmain team
Looks like they have just added some extra stock to the website. Just ordered my first 2 miners  Warning - don't use this link, it's not Bitmain. |

Scrapp out' Doubtful that it will be quite. Just for better cooling Then why the double fan? Think about it, it's barely higher in hash rate than previous, yet has 2 fans. As a previous owner of damn near every model they have made, double fans = twice the silence. I may be completely wrong, but that is my experience with bitmain. Scrapp out' |
