At some point you'll realize that your valiant efforts to calculate best value are fruitless. Miner's are being given only what little incentive they need to purchase and there will come a time if you're to stand a chance you must align yourself with ASIC makers if you're to remain in mining at all. You either invest in BTC or you invest in the mining equipment manufacturers. Sooner or later the little guy is out.
bullsh*t. big miners will be taxed. The little guy can run a few kW of equipment without being taxed as a bitcoin business - so the hashrate will always be able to distribute. even in GPU days there were people with warehouses and attics crammed full of GPUs

Bitmain advertises 180GH. it can overclock to to ~205GH
180gh is after bitmain overclocked the chips. Since day 1 they advertised 1.5gh per chip at 0.68w/gh before they overclocked to 3gh per chip at 1.2w/gh. My two cents, Antminer S2 uses the same ASIC as Antminer S1 Antminer S1 = 2 W x GH = 2.8 GH x Chip = 180 GH with 64 Chips Antminer S2 = 1 W x GH = 1.6 GH x Chip = 1000 GH with 640 Chips Regards Juan

Caveat Emptor! Information asymmetry detected.
ITs not meant as promotion for BFL, Id be the last person to suggest you order anything from there. But the chart is interesting and relevant to earlier discussions about how you can scale power efficiency of every ASIC. Even if you take those numbers with a table spoon of salt, it nicely illustrates my point. There is about a factor 3x difference in power efficiency depending what voltage/frequency point you pick. That spread is not going to be vastly different for any other bitcoin asic. I'm going to pretend it is relevant and probably valid for other ASICs but the fact of the matter is, the price of the devices are set many months before those cute little graphics come out. Your money has been spent and if the device you spent it on wont make a positive return for you running at the right-hand side of the graph, it certainly wont make money running on the left-hand side. Ergo, the plot is meaningless to anyone but the salesman and the scientist. Maybe I am missing something. What do you think your options are now that you have this information? You're missing the fact there is/was a discussion going about scaling of power efficiency. For every asic you could draw a similar plot, and power efficiency can be traded for performance per chip. Something obvious to anyone who knows anything thing about asics, but apparently impossible to grasp for jimmothy. As for pricing, current market prices are so far detached from variable production cost, that for now, this is a moot point. Vendors will charge whatever fools are willing to pay, there is basically no correlation with production costs yet. That will only happen once price per GH has dropped another order of magnitude or so. As for my "options". The only sensible option is the same one since the very first asic was announced: stay away from them, just invest in bitcoin. Doing that has yielded me 100% BTC denomnated ROI or ~10000% when expressed in dollar. How many miners can say that? You're right. Not many miners can say they have made that kind of return. I would suspect if they are still in the game, they are simply hoping to get a small percentage of the coins back that they forked over for the latest generation of pre-orders and wondering what to do with all the waste heat when they finally arrive.

What this likely means for mining equipment providers is that in the intermediate term the ability to migrate and maintain beats efficiency. That's why developments by Allied Control are so interesting which focus on ease of deployment.
Here you're opening a whole new can of worms. I think that would depends on your OPEX. CAPEX is high with the tanks but if maintenance (OPEX) is low enough, it would be a decent target for countries where labor and space are expensive (but what of electricity costs, what of heat dissipation power usage?). If OTOH you have cheap labor and space, the tanks aren't looking that good anymore. Also, unless there is a way to stack them, they won't really help you improve the density of your deployment (they have other issues with connectors, plumbing, etc) vs a regular datacenter (more on that after the end of June, I guess). I'm not really sold on the tanks, I think the idea is neat, but the numbers don't convince me so far (probably need more data). The OPEX and CAPEX of immersion cooling is lower. Unless you are talking about some home miner of course, not the 1.2MW container mining units. Isn't immersion cooling incredible expensive? No it's not. 3M fluids and immersion cooling have a reputation of being more expensive. What most people forget is that you only need very little fluid for a lot of heat, and that a tank full with hundreds of boards costs a lot less than dozens of racks with machines with cases or fans.
To give you an example, we cool 4kW (4000W) in a small space of 1 liter volume with only 200cc of fluid. Even heatsinks and fans for hardware with 4000W will cost more than just 200cc of fluid. And that is just one side of the equation. To make a long story short, it is less expensive to build and to run. That's the value proposition of passive 2-phase immersion cooling.
If you factor in device cooling (heatsinks, cold plates, pumps, hoses, radiators, speciality racks, air conditions, etc), it costs less to build a container with a few tanks from the first day. But where immersion really shines is when you start reusing all of this for your next-gen hardware, you basically get everything for free, you already own everything you will ever need. A single person can deploy hundreds of boards within hours, instead of days or weeks.
The reduced electricity cost for cooling is a bonus on top of all that.

Right? And if Friedcat has chips in hand for 5 weeks+ ? What is he doing again ? So he ordered 850k chips for April ... is May, where are they ?

First of all, where does it say he has them on his hand for 5 weeks? Second, they are in the the hand of the packaging factory and the board designers. Wafers are just that, wafers. They need to be cut into dies, then packaged, then tested, and all that. And of course he is also taking his well deserved nap. Just as any good cat would, at this time of the day. No matter in China or otherwise. Hope that helps.

That is for 32,000 AM BE200 chips. No plumbing issues. I am totally sold  Well, OPEX would be about 20-30% cheaper for me in a DC for a 240KW farm (includes electricity and rack costs). It gets slightly worse if you include CAPEX (but I haven't because I'm not sure of the useful lifetime of the hardware).
With 120 racks (2KW per rack), I would also get a better rate than the one I currently have (I could theoretically also build my own, but I would still be smaller than the ones with multiple DCs and they would still have better yet electric rates - a big factor here is the electricity "transport" cost, also there'd be all the associated building management "stuff" to deal with).
Setup would be more expensive in a DC than for a tank, but the OPEX difference is so big that it wouldn't matter.I'm in a densely populated, high electric cost area. The tanks would look much better if I lived, say, in Washington state.

If you are in a densely populated area 6 tanks with 1.2MW total would take a lot less space than dozens of racks? And in a place like Washington with $0.02/kWh cooling would be relatively small, no matter you pay a lot or a little?

This post is 5 weeks old. Chips were tested 5 weeks ago. Read more carefully. He was "napping" past 12+ months, no time for nap now ffs. To be fair, those were the test/sample chips. There'll have been several hands full, but no volume whatsoever. Those chips were used for initial testing and sent as samples to large potential customers and hardware engineers. Friedcat most likely ordered the "May batch" as soon as those preliminary tests proved to be successful. That may batch may have arrived by now and even be distributed, ROCKMINER populated at least 2 larger boards a couple of days ago. But There's really no reason to believe FC isn't doing anything. Do we actually know how work it takes to convey such a big operation and sell millions worth of chips? FC may have used the money from the first batch to pay for the June/July batches. He may be tied up with other stuff. He may as well be in the process of converting millions of US-$ to BTC and simply wait until all the deals are final until he forwards the proceeds irreversibly to the shareholders.

The plan was to take delivery as follows. To be fair it was stated divs would be paid 27 May and we haven't posed any further questions. Additionally we lost our ability to see what was happening in the boiler room when erpao.info went offline a couple weeks ago. Submitted Questions: 1) What is the status, size, and expected delivery of the next batch of chips? What about the one after that? re 1) This month: 850k, next month: 3.35m (order size), June: 6.7m (order size), assuming each chip is 10G.
"This month "was April.

"This month "was April. Yes, assume there've been no delays and everything went fine. Friedcat may have shipped those chips, those deals need to be "final", i.e. no hardware failures AM is accountable for, fully paid, etc. This being said, expecting dividend payments for that batch already may be a bit premature. Maybe fc used the money to pay for the June/July batches, as well. This may cost us our "first" gen 3 dividend, but may be a smart move business wise, as well. The thing is, we don't know anything for sure and may only speculate. I'd love more information and quick dividends as well, but that's probably not how things will work out. Yet, I am convinced everything'll work out and trust FC's words.

"This month "was April. So now will people agree with the fact that i was right and we will not see 109PH in the wild in the next 2 months? That seems to be a big radiator for just a few chips.

That seems to be a big radiator for just a few chips. Well, that setup consumes at least 140W, some people claim even more. That's 1.5 good old lightbulbs you need to cool. Radiators don't account for that much of the price, so why settle for less, especially in first iterations of the miner? The cooler the better. edit: I was wrong. This is the 4 chip solution. So at least 24W, but the fan size really is just a normal case fan. The gridseed miners look a lot like this.
