Title: ASIC power consumption estimates
Post by: jamesg on September 30, 2012, 04:23:57 PM
Hello fellow bitcoiners,

I was going to post this in another thread, but I think it's best to make a new post.

One of the biggest costs in running mining equipment is going to be power consumption. 1Gh/w is far and away the BEST offer in this area thus far. We've had others offer estimates so far, and to be fair, these are all estimates until the equipment is running in the hands of the community.

  • BFL - 1 watt/Gh +- 10% source (https://forums.butterflylabs.com/showthread.php/16-Announcement-BFL-ASIC-Release-specifications)
  • Avalon - 2-6 watts/Gh source (http://forum.bitsyn.com/viewtopic.php?pid=10#p10)
  • ASICMINER - 4.2 watts/Gh source (https://bitcointalk.org/index.php?topic=99497.msg1238486#msg1238486)
  • bASIC -2w/Gh source (https://www.btcfpga.com/forum/index.php?topic=4.msg132#msg132)
  • DeepBit "Reclaimer" -???/Gh

Avalon seems to be unsure of their power usage, thus the wide range. ASICMINER seems pretty sure of their wattage estimates which are 10x more than BFL! I'm not sure about you guys, but 6x the power consumption when you start running any sizable amount of equipment is HUGE.

If there is more info out there that I have not seen, leave a reply and I'll add it in.

Best,
gigavps

Having already ordered a jalapeno, I'd say im pretty happy that the power usage will be so low. If I can run this straight from the usb ports on my raspberry pi, I will be very happy.

If these generate a considerable amount of heat, I might even use it to warm my little sisters hermit crab tank, and heaters like that use around the same amount of power.

I just wonder when the new "little SC's" will be available, I might purchase one if I can somehow use my jalapeno order towards the price.
Its cool to see all these asics popping up, I wonder what kind of miners will come up next? Huge supercooled quantum miners?

  • ASICMINER - 10.64watts/Gh source (https://bitcointalk.org/index.php?topic=91173.msg1062854#msg1062854)

Final specs have been revised.

4.2W / ??? - revised hashrate has not been published.  Assumed to be around .5-.7 GH.

Power consumption is the topic of the thread!   ;)

If I have missed any information though, please let me know. Hopefully other manufacturers will be able to give estimates with as much certainty as BFL.

power spec is given as J/GH not W/GH/s. The reason is that chip GH/s performance is rather irrelevant due to minimal hardware costs.

I would like to keep the comparison in wattage. Are joules a 1:1 to wattage?

Joule is energy, Watt is power.
1 joule = 1 watt-second.

Cablepair stated the bASIC would consume less power than the mod miner quad (40 watts), but this was back when it was a 27Gh/s unit.  It is safe to assume the 54GH/s unit would required twice the power and consume less than 80 watts.

80/54 = 1.48 J/Gh

Having already ordered a jalapeno, I'd say im pretty happy that the power usage will be so low. If I can run this straight from the usb ports on my raspberry pi, I will be very happy.

If these generate a considerable amount of heat, I might even use it to warm my little sisters hermit crab tank, and heaters like that use around the same amount of power.


Most heat generated in electric appliances, electronics and computer gear is caused by inefficient use of electricity.  For example a 100 Watt bulb is drawing 100 watts, but not all 100 watts is going into the creation of light, a lot of it is wasted in heat, and that's why the bulbs get so hot.  Same thing with your CPU or GPU.  The heat is just electricity that's not being used efficiently, so it gets converted to heat.

I'm guessing the ASIC's must be pretty efficient, but even if you look at the worst case of 100% heat loss, you're only look at a 4.5 watt or 60 watt heater.  I'd be shocked if even the SC puts off more heat than a single GPU, and even then, that's a stretch.

It will give off 100% of the energy it uses as heat.

So, if that's the case, you're not looking at a huge amount of heat at all.  Your normal hair dryer is like 1875 watts.

Tom said exactly in the above comment "[the 27Gh/s device] uses less electricity than the ModMiner Quad", so it is pretty clear to me that it means less than 40Watt. Hence 675 Mhash/Joule, or 1.48 J/Ghash.

Now if you wanted to be pointy, one could say that Tom did not promise the 54Gh/s device would have the same efficiency as the 27Gh/s one...

I would like to try and make sure that I am not putting specs down that the manufacturers have not released. While you are quoting him, he could have meant that statement in multitude of ways.

For instance, did he mean total power consumption or Mh/s per watt?

One of the biggest costs in running mining equipment is going to be power consumption.

A 1,500W BFL Mini Rig SC costs $5.40 per day using the U.S. average residential rate of electricity around $0.15 per kWh.

So that is under $2K USD per year in electricity.  For an investment of $30K, $2K going to electricity isn't a particularly huge issue, though definitely operating one where electricity costs are $0.03 per kWh (like it is near Hydro electric generation) is going to be more profitable than running it where electricity costs are above average.

This compares to GPUs whose capital costs were low compared to the cost of the electricity to run them.

For comparison, a $1,100 GPU rig consuming 700W has electrical costs of $2.52 (using U.S. residential average of $0.15 per kWh) and $919 per year.

Of course, figure in the cost of capital per hash and this difference is even more pronounced.  Capital costs: GPU rig: $785 per Ghash/s.  ASIC rig: $30 per Ghash/s.

So ya, the cost of electricity is becoming much less of a factor than it used to be.

I disagree. Cost of electricity is always the number one concern when mining because you are essentially turning electricity into bitcoins. Cost of equipment is number two, and only matters when you are buying equipment or considering selling it. Since equipment isn't 100% liquid, it's the electricity cost, difficulty, and exchange rate that you are watching on a day to day basis, i.e. "should I mine today or turn it off." Furthermore, if your equipment is more efficient than everyone else's (or your electricity is cheaper) you will be always be able to keep mining, in theory at least.


Title: Re: ASIC power consumption estimates
Post by: Inaba on September 30, 2012, 11:32:29 PM
I have to agree with fizzisist, ultimately it's going to eventually end up at the cost to run whatever mining hardware you have.  The initial costs will be paid back at some point, so if a unit costs 2x as much to run, the value of that equipment is 1/2 comparable equipment that is 2x as power efficient, even if the initial costs are the same or even higher.

But it's even more counter-intuitive than that - your ROI is going to be cut by a factor equivalent to the difference in power consumption over the term of the ROI... I think I phrased that right.  So if your unit is 2x a power efficient, that also reduces your ROI time factor, even if you disregard your profit after the ROI has been met.

It's all about the power efficiency in the end.

It just amazes me to see BFL claiming to have reached 1J/GH. If it were April 1st I would be assured it's a joke. I simply don't understand how they could push that technology so hard in such a limited amount of time, and competitors don't get even close to it.

Thanks for the link. Is there any indication that BFL is doing 65nm? AFAIK the lower you go the higher the risk that the chip is a total failure, and you have to go back to the drawing board. Small problems can be fixed after the chip is produced, but that also requires some engineering time.

Actually - up front the power performance really doesn't matter at all - it's only in the long term if difficulty rises orders of magnitude faster than the BTC price rises.

Consider today - I can run 560W of mining hardware for about $80 a month in an expensive energy price country (Aus)
My 560W produces almost 1BTC per day - but with $12 BTC that's approximately $300 - $80 = $220 profit a month and the cost is about 27%

If I switched to a 54GH/s bASIC miner for $1069.99 from http://www.BitcoinASIC.com and it was using (as a random number guess) 60W, then that would be at the moment around $8.80 a month and produce approximately $6,931.83 profit a month - so only 0.13% energy cost

Now when the difficulty goes up 10x, if the BTC price stays the same at $12 (and doesn't go up) that will of course be 1.3% - still seems small ...
Double that power and you get: 2.6% ... still seems small ...
20x difficulty and double power: 5.1% ... still not a big deal yet ...

By the time it matters, anyone who cares about that number may well be using the next generation of ASIC devices ...

... though I don't think anyone has proven any power 'facts' yet ...

Edit: Oh I should add:
20x difficulty, double power, half block reward, still $12: 10.2% - I could deal with that :)

There's no chance you'll be able to run the Jalapeno directly off the USB ports on the Raspberry Pi.  You'll have to use a USB hub.  http://raspberrypi.stackexchange.com/questions/340/how-much-power-can-be-provided-through-usb

I agree with the disagreement :)

In the long-run, the cost of the electricity is THE factor that will decide who keeps his/her ASICs plugged in and who will turn them off. The race to bring the most Gh/s/W is on and the winner(s) should sell the most ASICs in the market (all other things being equal).

Once you buy the equipment, the money paid should be considered sunken costs unless you plan to resale the equipment in which case you need anticipate resale value and/or time timeframe needed to recoup the investment.

To quote Obsi:
Quote
With the reward halving and coming ASIC price wars we might see first gen ASIC miners with high electricity rates priced out of the market sometime in 2013.

Maybe it's because they are producing a Full Custom ASIC where the others use Standard Cell designs:

By the way, BFL doesn't use the phrase "full custom" to mean the same thing it means in the industry.

We don't?  Please elaborate. (I'm serious, I'm not being snarky.  If we/I am using it incorrectly, then I would like to use the proper term.)

Standard-cell ASICs and synthesis-flow ASICs are not considered full-custom (http://en.wikipedia.org/wiki/Full_custom) chips.

The phrase "fully custom" is a BFL-ism that sounds a lot like "truthiness" :)  In fact the third google hit for "fully custom asic" on the entire interweb is BFL which ought to be a hint that it is a contortion of the usual industry terminology...

Of course that assumes they're being on the level with all of these statements.

IMHO, I believe that BFL have learned the lessons of the past with underestimating power consumption and over estimating Mh/s. I also do not believe they would be using the phrase "full custom" unless they were doing just that.

You (and Tom) are dreaming if you think it's going to run at 60w.  The reason he doesn't want to post his power specs is because he knows they are going to be high.

Why is it attainable for your company but only dream-able for others?

Because BFL is using a 65nm process and Tom is using 130nm? That's a 4x difference in power use right there.

Actually, I'm not sure what Tom is using. Maybe I'm thinking of Avalon. Anyone know for sure?

3, this ASIC will manufacture by SMIC or TSMC.  0.11 or 0.13 process.

There the Avalon feature size has been stated.  I don't think I have seen either BFL or Tom/cablepair mention their process feature size.

Just updated the OP with new info from the ASICMINER thread. ASICMINER's estimates that they are going to be 4.2x the power usage of BFL. That would mean 4.2kW per Terahash! So, hypothetically, if you compared 1Th of asic miner to 1Th of BFL:

ASICMINER       1Th/s    4.2kW            3,066           $0.11           $337.26
BFL             1Th/s    1.0kW              730           $0.11            $80.30

The electricity costs are only important long-term. ASICMINER consciously decided to go for an older, more reliable technology, because it minimizes the risk of the chip being DOA, which can happen with newer tech.

I'm going to assume the initial costs are also significantly cheaper. But we don't have word for bfl or btcfpga on what type of technology (device size) they will be using yet.

I have yet to encounter a US house with outlet circuits rated for anything less than 15A.  Maybe it's different in other parts of the world that run on 120V (or 110V).

1500W consumption seems to be the upper limit for commonly encountered 110V/120V devices, I guess because 15A is all the makers count on being available at an outlet.

People wired for 220/240V power are at a definite advantage when it comes to being able to easily run higher wattage appliances.

The singles ended up using 4 times as much power per Megahash as BFL claimed they would initially. What's to stop that happening again?

However, I guess this time around there's unlikely to be any quantum leap in hashing rate on the horizon... what really comes after ASIC?  :D

I never meant to suggest that a 20x increase would happen again. But doubling every 18 months is still an interesting thought. Plus, we are seeing that most ASICs are on old nm processes, so they can be improved more quickly.

Yeah, I don't think you can use Moore's law in this case.  Moore's law considers the same type of technology (CPU's) increasing in effiiciency/power over time.  We're actually looking at jumps to new types of technology.  I think you need to compare the jump in power/efficiency from CPU/GPU/FPGA/ASIC mining to something more akin to the jump from Horses to Cars to Aircraft...

Because BFL is using a 65nm process and Tom is using 130nm? That's a 4x difference in power use right there.

Actually, I'm not sure what Tom is using. Maybe I'm thinking of Avalon. Anyone know for sure?

Tom is using 90nm and has further stated that the bASIC 1 will run on a barrel type connector or molex, this means under 110w.

https://www.bitcoinasic.net/index.php?route=product/product&product_id=51

Given the complexities/risks associated with designing a 45 or even 65nm chip I think a 90nm ASIC was an excellent choice for a product introduction.

We are expecting the 27Gh/s units to use between 50-60 watts and the 54Gh/s units to use between 100-120 watts give or take

There's the reliability of the estimation to account for too:
  • Tom said Nov/Dec from the start and seems still on track. He delivered the modminer quads in a timely manner too from what I can tell.
  • BFL originally said October then November and now December and has a past history of optimism.

BFL seems to have far more customers being the first announcing ASICs. So even with more hands to handle the task and an optimistic early start Tom customers as a group might get their ASICs before the BFL customers do and overall see a better ROI. So the luckiest (first delivered) BFL customer might have the best ROI of all but a random customer might be better off with Tom's offer.

I hope we'll have a clear picture at the end of December.

It is unknown (as of yet) if this is simply a prototype for the case design or if it is a fully working prototype.

Oh, by the way, the prototype picture has been released.

Re-posted under the FAIR USE ACT for discussion purposes.

It is unknown (as of yet) if this is simply a prototype for the case design or if it is a fully working prototype.

If it is the latter, then obviously the burning questions is: Did it meet the power and efficiency ratio of 1Gh per watt? I'll let others ask....

That's just the case,is what I gather from what he said:

"This is a crappy picture... I will get a better one when I get some time, but it's one of the prototype Singles cases. What you actually receive may be subtly different, but not much."

It may have one of the "dummy" boards in it,for whatever reason.

Perhaps for the purposes of confirming the outer housing is actually within manufacturing  tolerances?

Either way, now it is bASIC turn to upstage or lay like a dead goose in the background.

So guys...If I ordered a BFL Mini Rig SC today, when can I expect it to reach my house (SE Asia) ?
"By the end of January assuming no snags or anything."

EDIT: sorry, that was for the pre-orders. february maybe? 4-6 weeks into 2013?

There is speculation that the picture is only a non-working dud as of yet. Hopefully they will have working prototypes soon.

One representative stated that they won't have any samples in the incoming batch. So if it is broke, then the fat lady has sung. They said that was unlikely though. I believe them on that. Question is, how many times did they try and when did each iteration occur in their timeline/schedule?

That info alone would change the actual reasons for the past delays. [or at least solidify that there was never a possibility for shipping earlier until just now.]

It seems to me like there is a 0% chance that thing works. It's all for show.

How could it work if they don't have any working ASIC chips yet? They said they would update us when they received them.

i have this waiting to power 3 bASIC devices, should be roughly 65-70% load..

Do producers not know the watt usage yet or is it a secret?

Like Avalon it's specified as a range for bASIC. Only BFL has use of a crystal ball and can perfectly predict power consumption to the watt across an entire product line. Naturally no on questions this crystal ball prediction as BFL's track record for predicting power consumption in the past is exemplary. ::)

I think the main issue here is that no vendor has (demonstrated) a working prototype yet. So it is difficult for them to estimate, let alone commit to, final power consumption numbers.

Some have chosen to express it as a range. Others have refused to commit. BFL has thrown out a a number (1W/Ghps). We all know that BFL has taken a lot of flak with their FPGA product in that their final power figure was 4x greater than initially estimated. I like to believe that they have learned their lesson, but we have to wait for prototype testing results (from all vendors) for anything more concrete than that.

One other other thing to consider is the fact that BFL has chosen a 65nm process node while the other vendors are using something larger. This implies that whatever the final power numbers end up being, BFL should be lower (per GHps) than the others. Whether this becomes a significant differentiator remains to be seen.

I'd call 1.4W/Ghps reasonably competitive with BFL's estimates of 1W/Ghps, though I can see that may be a restriction for some people. Ultimately, until a working prototype is demonstrated from any ASIC vendor, power claims remain as estimates only. Reality may turn out to be different. I do hope the estimates turn out to be largely accurate.

The fact that BFL decided to produce their chips in a smaller manufacturing process than the competition, it's really hard they could beat their energy efficiency.

With the announcement that the bASIC was moving from 54 to 72GH/s, it was stated that more chips would be used per device. 16 chips at a lower clock and lower voltage will not only be faster, but also more power efficient. You can bet your ass their old 54GH/s design wasn't 1.4W/GHs.
