I'd be interested in around 1,000 chips towards the group buy.
https://products.butterflylabs.com/65nm-asic-bitcoin-mining-chip.htmlIt looks like they are for sale now. $75/each (Much better price) What is the status of this thread?
I did hear that prior to the price change they would be giving discounts based on quantity, hopefully this translates into even better prices for the group buy.
LoL!
They aren't selling at all compared to the Avalon chips which have a known working implementation.
Seems they slashed the price by [very roughly] ~25% to try to lull people into buying chips without the board....Yikes...
Reeks of desperation.
The old offer:
Original message by Josh:
Butterfly Labs will begin selling bulk chips to individuals and companies starting in June, 2013. Chip delivery schedule is approximately 100 days through end packaging once your order is placed. We will be providing reference documentation, reference design/schematics, and foundry receipt/documentation.
Grade A chips have 16 engines and will do 250 MHz comfortably, equating to 4 GH/s per chip.
Chips will be graded and priced as follows:
Grade A: 16 Engines - $97/chip
Grade B: 15 Engines - $93/chip
Grade C: 14 Engines - $89/chip
Grade D: 13 Engines or less - $83/chip
Our chips will be provided in minimum lots of 100 with the following price structure:
100 - 999 chips - Regular Price
1000 - 9999 chips - 5% discount
10,000 - 99,999 chips - 10% discount
100,000 or more - 20% discount
Chip orders will require 50% down and 50% upon order delivery. Payment can be made via BTC (preferred) or bank wire.
Advantages of BFL chips:
1/2 the power usage per GH as the closest competitor
1/10th the silicon area per GH as the closest competitor (Very high performance density)
You can use off the shelf heat sinks depending on your chip layout due to FCBGA package vs custom underside heat sinks as required on some QFN packages. You don't have to design and manufacture heat sinks!
Proven design currently operating in the field and ready to go.
I noticed on their site it now reads that they are selling mixed lots...?
Does this mean they are no longer sorting out the Grade A's from the D's or what?
Is this going to be like an easter egg hunt where one has to figure out what chips are grade A's? Also read yesterday that they want the buyers to create their own firmware. Kind of a tall task! (Can't they just give the board makers their own reference firmware(s)?)
If they keep making it harder and harder to turn those chips into actual mining rigs they might as well keep slashing the damn prices! Gonna need to pay a whole development team just to figure it all out.
