Your comparing a over clocked product to a stock one.
16 Chip biburner furry stock is 16*2.7 ~44ghash 925EUR= more than 925 when you account for exchange rate. (USD>EUR)
8 chip barntech stock is 8*2.7 ~ 21.6 for 425USD

Right from the site:
"Each board will have a performance of 40 to 80 GH/s (best demonstrated 64 Ghash/s). Tests of a single chip have already given a result of 4 GH/s with 4,5 watt of powerconsumption."

SO worse power consuption, and equal performance to maybe better.

(exchange rate EUR/USD = 1.3355)

I care about what GH I get for my $

933$ for 64 GH Bitburner Fury early October

1275$ for 64 GH Drillbit late October/begin November

They have also a hashrate protection: If 64 GH is not achieved a discount of 133$ (100) is given...

Actually its more like this:

$933 for a 16 chip Bitburner Fury in early October at the earliest.

$850 for two 8 chip Barntech Drill Bits in late October to early November at the latest.

It is possible that the Barntech boards will overclock very well also. Just throwing that out there.

Hey guys.

Thanks everyone for putting in your two since regarding BTCguides statements. Some pretty spot on points have been made. Firstly, we're not out to fight or compete with Burnin. If you weigh up all the facts and decide to go with his stuff, that's fine. I'm just happy to see people supporting DIY developers over the big guys.

In terms of comparing the two, i think the appropriate comparison is price per chip, the rest is basically conjecture at this point. We are offering a cheaper price per chip. They are the same chips. In terms of delivery date, we are bound by when we receive the chips, which is unfortunately still not entirely clear, but the official line from Dave is early October. If Burnin has access to earlier delivery chips that is certainly a bonus and the extra few weeks hashing will make a difference for sure. Unfortunately there's nothing i can really do to get the chips any sooner. It does seem like a strectch for Burnin to be promising early October delivery as there doesn't even seem to be a prototype yet.

In terms of the hashing rates, it is well documented that the sweet spot for power efficiency is around 2Ghs on the Bitfury chips. As you push them higher, you will be drawing more power and thus the extras gains in hashing power will be offset or completely cancelled out by the extra power draw. You will also be looking at serious heat and potential short running life for your equipment hammering it that hard. The 4Ghs per second that Burnin has reported is not a regular, reliable, stable rate, it is a one off fluke (please prove me wrong here if am), so it seems to me that guaranteeing 64Ghs for 16 chips (ie 4Ghs each running constantly and stably) is a bit of a stretch. 80Ghs is is 5GHs per chip. No one anywhere has achieved this. 40Ghs is 2.5Ghs per chip. More reasonable but still on the higher end of things. If he has indeed found a way to run these chips hard without getting to crazy power and heat, i'll be very impressed and excited to see it. I hope that is the case, but i doubt it. As for our stuff, we will push them and prod them and tell you what we think is best we can get out of them in terms of GHs and efficiency.

Did anyone else notice that the photos on the Bitburner Fury sales page are actually of 20 chip Avalon boards? There is nothing there visually that has anything to do with Bitfury. That seems pretty odd to me.

Anyway, no intended diss on Burnin. Lets keep the DIY love!
