Here is a 3.1 terrahash/sec farm (for more info see https://bitcointalk.org/index.php?topic=303376.0):



Note: only about half of these chassis are loaded up with hash units.

I am simply showing you that ASICMiner produced 60-40 Ghash/s per $1k, which you doubted was feasible.



Every time another Avalon is delivered, you are losing more and more credibility. AFAIK you are the only one claiming that jgarzik, the Foundation, and all others who have received units are "part of the scam". I would be interested to enter in a personal bet with you that batch 1 will be shipped by some date.

So 1 month later, and plenty of Avalons delivered... I was right (again).
Why do people argue against me? They never learn  

I am sure someone like king_pin still does not believe in ASICs even though we have now 5 delivered Avalon units (jgarzik, the Foundation, techwtf, xianfu, and another chinese) I just cannot understand why you guys at some point did not believe in ASICs. It is a financially and technologically natural and inevitable evolution of Bitcoin, like pretty much all the other computing industries on earth!

Just wait a little more time for the entire batch 1 of Avalon to be delivered. You will see.


You are the only person who seems to believe that ASICminer spent more money [than other vendors].

We have proof that BFL have even more capital than ASICminer. ASICMiner's IPO raised only $200-300k while BFL has presold a few million dollars of devices (we have indirect proof through bitpay who inferred that $250k of ASICs were sold the first 24h alone after the opening of pre-orders) and BFL also claims to have investors (not proven, I will give you that). Plus BFL was already established business having sold thousand of FPGAs in 2012.

So if you base your beliefs on how much money is spent, if you believe in ASICMiner, clearly you should believe in BFL as well.

But this is exactly what ASICMiner has produced - and you believe them! 12 Thash/s divided by $200-300k IPO = 60-40 Ghash/s per $1k

You can say that ASICMiner could do it because their 130nm process is cheaper than BFL's 65nm, but BFL is financing themselves with prior FPGA profits, and by manufacturing a lot more chips to recoup the higher NRE - by all estimates they have 100-200 Thash/s of preorders...

Anyway we are getting off-topic here.

pekv2, you don't need 3 resisters per dummy plug. And you don't need the dvi-vga adapter either: http://blog.zorinaq.com/?e=11

Vladimir:   So, are you below or above 38 Ghash/s now? (Last time you said you were below ArtForz's 38 Gh/s)

In the same spirit, I racked these little guys today:

(Image fixed.)

Yeah he is at 55 Gh/s today.

Well, you can claim an impossible PUE of 0 :-)

PUE = facility power / equipment power
If you don't pay, it is as if you provide zero power to the facility, but somehow your equipment gets power anyway... magic yay!

Man, releases of many-PCIe motherboards have really come down to a halt in the second half of this year...

Anyone: any new motherboard release?

Edit: I think the screenshot showing "A3207" is a typo, and is meant to read "A3206". Edited the topic to reflect that.

Looks like redtheminer spilled the beans first:

• Product: AvalonMiner A9 series
• Speed: 26.5TH/s - 30TH/s
• Power: 1720 W (typical)
• Energy efficiency: 0.06~0.07 J/GH
• Chip: A3207 7nm ASIC
• Fan: 1x 14038 fan
• Note: Subject to changes(translation?)

You say A2 to A6, but I don't think you guys ever released the A3. It was supposed to be a Bitcoin mining chip succeeding the A1...

I added the RebTech 8GPU-MB:



Very interesting product and company. RebTech seems to have existed since 2015 (http://rebtech.ro) but they are now designing their own motherboard and even a custom GPU and they are advertising them on a new website (domain name http://rebtech.ai bougth 2 months ago.)

The mobo is very compact and has 8 PCIe slots exposed as USB ports (no need for risers on the mobo side). And RebTech also made a custom GPU with a USB port instead of the PCIe edge connector. So combined together, the mobo + custom GPUs (RX470 8GB) offers a completely riser-free setup.

No new hardware released in a month? Anyone?

Thanks. Added to http://bitcoin.zorinaq.com/many_pcie/
Interesting: this ASUS blog post reveals they sold "six figures" of the B250 Mining Expert. Assuming fully populated (19 cards) it means more than 20% of the estimated ~10 million GPUs in mining farms are running on the B250 Mining Expert.

Specifically they taped out 7nm in April 2018 and final products are arriving in the 3rd quarter (p. 118)

They had revenues of 1296 million RMB (203 million USD) in 2017 (page I-32). I agree they have zero intentions to abandon the Bitcoin mining industry. Working on AI accelerator chips is just a natural way to expand their business into other areas.

Thanks. Added. Based on the layout of PCIe slots present but not installed, it seems like they may have been working on an 18-slot motherboard...
