Avalon A7 is here

Canaan just dropped news about their new miner, the Avalon A7. Looks like they’re stepping up their game with this one. If you’re into mining, this could be a solid option to check out. For more details, peep the official site for specs and pricing. Let’s see how it performs compared to the competition.

- 6THash @ 900W @ $888 - 0.15J/GHash or 150W/THash/s - $0.15/GHash/s or  .21BTC/THash/s "Aluminum PCB" -> Presumably a MCPCB 72 A3212 Chips per miner -> 83GHash/s per chip -> Each chip is equivalent to an up-clocked Avalon 1.

I'm happy to see another <1KW miner.

Too expensive

I've had at least 20 Avalon6 come through hosting (most are still here), with two bad boards total. In about half as much time I've had around 25 S9 come through hosting with 4 bad boards total. I'm honestly surprised it's not higher than that. They do cost more, but there's something to be said about reliability (and, you know, customer service when something does go wrong).

Nice fake link there newbie

So now maybe Bitmain will start to sort themselves out and offer a real warranty service and possibly reduce their prices

I've been thinking Avalon was nearing a release. A few days ago their presence on CKpool (Canaan) jumped from 180THs to over 2PH.. Faboo!

yeah  I down with this.  note 8 pcie jacks  into 900 watts = 112.5 watts a jack. months ago when they were designing this gear they asked for community suggestions . I asked for more jacks to end cable meltdowns.  They listened and followed my suggestion for this alone I will get some . Are they cheap no they are not.  But cheap would only start a price war. I rather this price but  maybe a little better watts per gh. I can run 3 with ease on my dual dps 2000 4k boards. I think my first order will be for 2. If there is a Moq   of 10 I will do a group buy like I did last year.

I'm interested what the price would be for one with a group buy

900W is easy to pull off a 120VAC outlet too, which is nice. If I can stay in stock of boards and Phil does a group buy, I'll do 8-cable DPS1200 kits for $75 for group buy members who need a PSU.

Wow,you were right about some competition phil,lets hope ya'll get more from Bitfury

Rare that I quote with pics but for this -- just gotta do it. My benchmark is the s7's I have: The best ones, from batch 1 and 5 consistently average >5.3THs running 700MHz and pulling 1,350W. Using Sidehacks under volt/clock on most other s7's I have and running ~3.6 to 3.8THs they are pulling 930w. All using Bitmain PSU's btw. So bottom line for me: As long as they are as reliable as my s7's have been, 6THs @ 900w? Count me in for a couple! edit: As a side note, this rather sets a price point for Sidehacks 16nm project. How close the pricing should be, well, knowing Sidehacks work he *could* charge more if need be..

Interesting but I don't really see this being profitable, $888 for 6 Th/S isn't really all that good and for everyone with electric over .09 cents/KW this thing isn't profitable enough to even break even on the miner, then factor in rising difficulty and its really a total loss for most people.  It's not like you can really resell this for much after, look at the S5 its selling for like $40 now.

Can't look at it per-miner. Gotta look at farm income. Give the age of miners I have running most are long ago paid off and making BTC for upgrades. Even the latest s9 b18 I bought will paid for by the entire farm in another 7 days. Now, if starting from ground-zero with these, ja would be rough but I'd still take the risk. For me running 18x s7's (and 9x s9's) it is a good upgrade value for the s7's I have running. Almost 2x the speed vs uv/c s7's at same power per-miner.

I ran some numbers using this calculator: https://bitcoinwisdom.com/bitcoin/calculator And assuming a 5% difficulty change, free power, a 1% pool fee it would take over 400 days to break even. Assumptions: Breakeven table: Edited to add: Since I am starting from zero, this doesn't work for me. Running a different set of numbers: 2.5% difficulty change, $0.12/kW power, 1% pool fee That would require a BTC price of $1125 to breakeven in 500 days. Still not good for me.

Yeah sadly it's hard to justify looking at the numbers even with zero power costs.  The past two difficulty changes have been great though.

I'd be happier with them if they were a match per TH vs the S9 rather than targeting the R4 as their price match.  The "smaller" power footprint though is a good thing, and will help them sell quite a few miners.  Bitmain is only selling the R1 and the S7-LN <edit> on newegg and is sold out on the S7-LN already </edit> and those for a "limited time" and at a bit high pricing - I'd guess they're hoping for some "impulse buying" to clean out their stocks of those older units.  5% difficulty is a bit on the high side at this point I'd say, unless Bitmain drastically drops the price on the S9/R4 or gets someone that WILL compete with them on pricing (Avalon has never bothered, but they do tend to provide higher quality gear).

expensive, but it is good that Bitmain has competition.
