That's awesome. I've been hoping they would come out with something. They aren't the best claimed numbers, but they are back in top contention.

Really excited to see the offering, though they may miss it with only a couple days left in the month. Great find Hagss, I'm beginning to think I need twitter to find anything out.

I wish they didn't go with integrated PSUs. I don't trust anything other than server PSUs to deliver that amount of power without being electrical and fire hazards.

Yeah,
there will be a huge amount of good external psus which people can't use with their miners no more.

It seems that the 5-pin comm port, two of them, are still there in the front panel.
I like that they keep the idea of having a Rasp Pi controlling multiple miners.

They came up with the two tube  two fan stack for cooling  pcb board is shorter easier to cool them off.  Similar to bitmain, I am hoping the gear has proper down clock the A841 had good down clock ability.  While the a851 and a921 did not.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

I hope they get back to having true specs again.  Up until the A921, Avalons always seemed to do better than their advertised specs.  The A921 was disappointing on that front.

Ja. However, the integrated PSU's are a large part of the better efficiencies we are seeing from the new miners so that will remain the trend.

Even the best switching regulator designs are only pushing 98% Pin > Pout eff. More common is around 94% or less so using the PSU itself to set the voltage sent to the strings of chips saves several percent power eff per-board vs using 2 stages eg AC > 12V > hash board voltage regulators > chip strings.

Another bonus is that using more chips in each string allowing the higher voltages reduces the voltage differences that can appear across each chip in the string making it easier for tuning to find a stable operating voltage.

Nice, I saw this last night during my drunken twitter ranting. Waiting to hear from Liliy on pricing.

Nice, I saw this last night during my drunken twitter ranting. Waiting to hear from Liliy on pricing.

I was going to have some vanilla vodka last night I passed it by. Grin

If this does 31th at 56 watts a th it will do 1736 watts.

The real key to it having value is the down clock  say 27th at  45 watts = 1215 watts  or maybe 25th at 45 watts = 1125 watts

I could order 50 of these and replace the entire farm at Clifton.

50 x 1125 = 56.25 kwatts  
50 x  25th = 1250 th

and I would still have 18 L3+ units.

I now have  570th  at  50kwatts
and 18 L3+ units

I am eager to find out if these are good.

Ditto. After the 921' performing so disappointingly Canaan better pull a hat out of a rabbit Wink to get their reputation back. Perhaps offer some discount to those of us who bought the A921's?

I purchased 1 A921

And I tested 2 A851's    Both were Simply not good in efficiency and no clocks were helpful

I have always like dealing with Steve and Lilly  they even sent my partner buysolar to China back in 2018.

We can use a good avalon miner again.  Fingers crossed that it works well.

I could then write Avalon 1021 rocks on my logo  Grin

I've been wondering since the SP3x days how long it was going to take people to realize long tubes don't cool very well. Looks like more than just Bitmain are noticing.

Fuzzy, I'd be surprised if the main regulators on most recent miners hit 94% and above. High voltage is good for high efficiency, but 45A in a single phase really isn't, considering two of the main sources of loss in a buck increase with current squared.

Unless their PSUs are built very cleverly, going to an integrated PSU with no board-level regulation probably means all boards run at the same voltage. If that's so, the entire machine, instead of an individual board, has to run at the level of its weakest chip. If they do have separate independently-controlled rails per board though, that's pretty sweet.

I love canaans products the most, this is kind of another let down though.  Considering the m20 and bitmain now with the s17 are hitting essentially 30w/th numbers which is double in efficiency than this.  I prefer canaan for reliability and I love the daisy chain setup but ugh.  Unless the price is really low I don't see these selling much sadly

Specs are pretty close to the s15 and better than the m10. If they're shipping now it's well timed release.

well  lets see:

m20 is 48th  at 2200 watts = 45.8 watts   not 30 watts  these have been mentioned on pangolin
m20 is 72th  at 3300 watts =  45.8 watts  not 30 watts

s17 is ? the 30/j = a number for the chip  maybe just maybe they do 40 watts on low and 45 watts on high as a unit

a1021 is 31 th at  1736 watts = 56 watts  certainly not 30 watts

the key is  does it down clock  to 25th at 1125 = 45 watts

if you can go to 45 watts  it still has value.

if it is like the A921 and A851  where down clocks suck it will be a loser

All three units avalon whatsminer and bitmain  have yet to be demoed so what's the watts per th is not sure as of now.

Don't you think they added the (minimum 50W/T) inside their ad for a reason? Perhaps they already tested it and could not get any better efficiency from them? 50W/T is pretty good in my opinion. Bitmain's S17 is probably 45ish but they claim 35... Only a third party review can tell.

It is important for miners to know watts per th on this gear so

I contacted Steve of canaan for a demo to review.

Hi Steve,

I read about Canaan getting an A1021
https://bitcointalk.org/index.php?topic=5125803.msg50361384#msg50361384
https://twitter.com/canaanio/status/1111513725733724160
If you have a demo available I would love to do a youtube on it.
Best regards,

Philip Arcario

philipma1957 of bitcointalk.org

My goal is to show:
S17
M20
A1021
in youtube videos as soon as I can get the gear.  It will help miners pick what is best.

Ugh on this:

https://blokforge.com/product/canaan-avalon-a10-31th-s-bitcoin-miner/

1550 usd a miner not going to work at this price  Does Say TBD

I dont know about the new Avalons but many of the new units including Bitmains use 20v internal rails, 12v PSUs just wouldnt power the miner properly. Its not that they are trying to force us into their PSUs, they are just a requirement for the unit to function.

Not yet, at least. But sarcheer's M10's PSU did try to put on an early Fourth of July fireworks display.

I find these PSUs' general lack of safety certifications disturbing.
