Right, I think we have to call the bet a no contest (draw). Depending on temperature conditions, I can make the unit do whatever outcome you want.

I can put it in 25C ambient and it will do 1.30TH @ 1250W at the wall.
I can put it in 37C ambient and it will do 1.23TH @ 1370W at the wall.
I can then put fans in turbo mode at any time and give it another 30W penalty.

tldr, it can achieve <1W/Gh, but it can also be made to go way above 1W/GH within its operating range. I don't think we're going to be able to conclude fairly on this one.

+1

PS: dogie i've been wondering, how many miners (and global hashrate) do you have running in your farm? could you share some pic of it as i am sure seing all time miners produced so far in one place should be quite amazing

Not much, I turn units over reasonably quickly so I always have capacity and flexibility to control ambient as required. I keep everything I test with me residentially as a lot of it (which you don't see) is preproduction which requires a lot of babying and is a bit too risky to leave unaccompanied.

hmm alright fair enough, but one day i sure hope you would open some sort of mining museum ^^

Why don't you mention about H/W error rate? This can bring your estimated 1.30TH @ 1250W at the wall to a significant lower numbers. Also, 25C^o is very uncommon for datacenters, you are looking more to 30C^o, if you will like them to be hosted.

So, please provide stats for 30C^o ambient, and real poolside accepted average hashrate.

Thank you.

I gave you a huge temperature range and showed that its impossible to call it because you can say "oh I meant at -20C ambient" or "actually, I meant 45C ambient like it says in their specs" and you get totally different results. Results from any one specific temperature are meaningless, its too close.

Hash rates are 'real poolside accepted average hashrate'.

And yes I did just use an image from teenmomtalk, deal with it sister.

Actually, datacenter cold aisle temperatures are typically between 20-27°C.

It would be only fair to quote hashrate and efficiency at these values, everything above 30°C might be bitcoin-mining specific, but not datacenter standard.


With improved PCBs and slower clocking chips, I am sure the target power efficiency of ~0.8W/GH can be reached.

However, you could probably build an S4 with 0.6W/GH with this level of optimisation, so why use the AM chips?

[gallery2000]

Do we get discount if we buy 5 units?

I am very sure you will, especially as this is China and there is always room to negotiate.

[notbatman]

... so why use the AM chips?

Could it be that if they used the Minion their claim to be a "New" ASIC manufacturer wouldn't fly. Also, if they're using Mr friedcat's ASICs what ASIC are they manufacturing?

14nm with 1024 cores, pre-order now?

In a real data centre where you use AC yes, not in a bitcoin data centre where you use a metric shit tonne of air per second per cubic mm as your cubic method.

Oh! You bad dog! You bite without a reason! I'm a have you neutered for that!

 

[Collider]

You can get the quoted temperature in bitcoin mining facilities easily by using evaporative cooling and/or building them where it makes sense (aka Iceland, WA state, virtually anywhere in Canada, Sweden....).

I am just saying, those are the usual temperatures and it woul be only fair to quote power consumption at that temp.

Do we get discount if we buy 5 units?

Why is anyone considering buying this inefficient, outdated trash?! That'd better be some STEEP discount.

Inefficient? The entire consumer market is sitting around 1W/GH in real terms.

What do you think should we buy?

good price here

Don't post stuff like this even in sarcasm, it gets archived and newbies walk past and don't realise. That site is a scam.

Ah it's a great thing seeing this bet finally settled! I think it's a nice thing if you both agree to donate the bet to Seans Outpost! It really seems like a draw, given the measurements by Dogie.
A bit disappointing that the miner is indeed not achieving 0.8w/GH/s, but it's still good to see they're delivering!
