Josh said 1st week of December for shipping. Tom also said 1st week for the bASIC. Are people sweating now over their who will ship first bets? Grin

I would guess only the very early BFL customers who were relying on being first. Most bASIC customers went into it expecting to ship after BFL.

It seems that they will start shipping so close together that it won't even matter. Except for maybe the people that are very first in line.

More info has come out about BFL ASIC. Shocked

Looks like Tom has posted power estimates after all.

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

this is estimated data - and will not be completely correct but it gives you a ballpark and as close as an estimate as our competitor friends have on their units

Quoted here for posterity. I have also updated the OP.

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.

Avalon announced a maximum of 400w for 66Gh/s.

We can narrow the estimate for Avalon to : 2-6 watts/Gh

Done.

BFL - 1 watt/Gh +- 10% source
Avalon - 2-10 watts/Gh source
ASICMINER - 6 watts/Gh waiting on source
bASIC -???/Gh
DeepBit "Reclaimer" -???/Gh

The ASICMINER source says 4.2 Joule/Ghash:

(BTW, fix your units, it's either Watt/Ghash/s or Joule/Ghash Tongue

)

I really hope that BFL can deliver

Moore's Law and higher nm processes.

True, but say you had a basic $1200 budget:

2010: ~10-15Mh/s
2011: ~1400Mh/s
2012: ~2200Mh/s (achievable with cheap GPUs)
2013: >50000Mh/s

As much as Moore's law etc will have an impact, I don't think we'll ever see hashrate/$ go up >20x in a single year again. Hope not anyway Cheesy

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...

Or they run two 1200W PSUs instead of trying to source a 2kW model

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?

I usually learn lessons the hard way, but once they are learned, they are not repeated. I hope it is the same with BFL.

...

Actually ...

This time they have to be at least 10x better than they were last time ... do people usually get that much better per iteration? Cheesy

Before was 400%

If this time they are 10x better at estimating, i.e. only 40%, then the 1.5kW becomes 2.1kW = 19.1A on 110V .........

yep. ASICs are endgame.

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.

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:

Code:

             Terahash    Power    Monthly Usage    Avg. Cost kW    Cost per Month
ASICMINER       1Th/s    4.2kW            3,066           $0.11           $337.26
BFL             1Th/s    1.0kW              730           $0.11            $80.30

I don't know about you guys, but that BFL equipment, if delivered as expected, is going to be able to run a lot longer with increasing difficulty compared to ASICMINER.

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? Cheesy

On cheap power you're hopefully looking at a multi-year service life on these.
