Tough Questions about the Monarch Card
QHey you Jerks, what are you doing announcing 28nm gear while you're still shipping 65nm? I want my Single!
65nm products are shipping in volume, but they'll be out of production before the first 28nm Monarch cards are through development and ready to be shipped. If you haven't already received your 65nm product, you will very soon. The ASIC engineering team switched to 28nm shortly after tapeout of the 65nm. Because chip development is traditionally a year long process, ASIC engineering teams work far in advance in order to deliver the best technology to the market. Please don't think that production of your singles ever lost a second to 28nm development. We've put enormous resources into building our supply chain & production capacity so that we can serve our customers. Nothing is more important than shipping your order as fast as possible.
QWill the power & performance really be that good?
BFL began making bitcoin mining hardware in 2011 with the announcement of the now famous FPGA 'Single'. The delivered speed was within target range, but the power consumption was higher than the design simulation indicated. The product was a smashing success.
With that experience under our belt, we baselined our models and started in on our next chip for what became the iconic FPGA 'Mini Rig'. That 2nd generation chip met both its speed and power consumption specs with perfect accuracy.
How did we get perfect accuracy? We were able to use real life data in our simulation models from the prior generation chip.
So fast forward to our first generation ASIC chip which was an original design. We delivered exactly the speed promised, but the power consumption was higher than predicted. That caused a controversial release delay while we adjusted the PCB to accommodate additional power. That 65nm ASIC chip is now powering the majority of the bitcoin network. It's an excellent chip and its real world data has given us the bench test results needed for baselining our simulation models when we began optimizations for the 28nm chip. We are confident that our Monarch will be able to produce 1.7 GH per Joule, an eight-fold increase over our 65nm ASIC products.
In sum, the value of a 2nd generation chip can't be overstated. It allows us to optimize with great vision and it takes the guesswork out of calculating power and speed in the final silicon design.
The bottom line is that BFL is the only 28nm chip manufacturer on its 2nd generation ASIC. If you want the benefits of a mature & proven design, there's only one option.
QCan I transfer my existing order into a 28nm Monarch card ?
You can apply the purchase price of any undelivered end-user product towards a 28nm miner by paying a 10% transfer fee. (This transfer cannot be applied to bulk chip orders.) That will close out your old order and credit your account towards the purchase of a 28nm Monarch pre-order. However, we do recommend you keep your remaining 65nm orders and take delivery because you'll get your mining gear much sooner. 28nm products won't begin shipping til year end and the network hash rate is expected to be much higher at that time. It's also worth pointing out that FPGA era products were still very valuable well into ASIC generation rollout, and the relative power difference between 65nm and 28nm is much much less.
To see how much transfer value you have, log into your account dashboard and follow the transfer instructions to jump queues.
QCan you host these for me?
Cloud hosted mining makes it easy. Although Monarch cards have a USB plug, so you can run them outside as a computer peripheral if you want, they've been design optimized for PCIe use in rack mount data center servers, or any standard ATX motherboard.
Butterfly Labs has arranged to provide cloud hosting of your Monarch cards with either Six or Twelve month hosting terms available at checkout. Your cloud hosted miner will be set up and made accessible to you online. All maintenance, hosting, power & software setup will be provided. All you need to do is configure your bitcoin wallet address and hit 'go'.
QWhy should I place my Pre-Order with Butterfly Labs?
Since 2011, Butterfly Labs has been the pioneer and leader of the bitcoin mining hardware industry. As we enter the 28nm era, we're the only competitor with a proven ASIC design in the field. We have 45 employees and a matured production capacity & supply chain. Our 28nm competitors have never delivered or even demonstrated an ASIC product of any kind. Their manufacturing, supply chain and engineering are all back-of-the-napkin ideas.
- Shipped more ASIC than all competitors combined
- 2nd generation ASIC
- 4th generation bitcoin processor
- Largest production capacity
- 45 employees strong with an experienced management team
QWhen do the 28nm Monarch cards ship?
We've been in development for approximately six months. We're now in the final stage of the process which is wafer start at the foundry. However, we aren't shipping anytime soon. This is a Pre-Order product, so if you're uncomfortable waiting an indeterminate length of time for the final phase, do NOT pre-order this product.
With that in mind, our current schedule is on track for shippments to begin towards end of year.
Here are the timeline milestones:
- Tapeout (Initialization of wafer production)
- Foundry production takes 10 weeks
- Bumping, Slicing & BGA packaging takes approximately 2 weeks
- Initial shipments begin and ramp up to full capacity over the following 3 weeks
Since this is our 2nd generation ASIC chip, we're largely free of risk from the pitfalls normally associated with a new chip design. Testing systems, Bumping masks, Substrates & under fill engineering are all carryovers from our proven design so they're complete and ready for high volume production once the wafers are ready. The importance of this can't be overstated.
"As a fairly early Bitcoin adopter and institutional miner, the choice for mining hardware comes down to innovation. Who is going to have the experience and best technology going forward to keep me ahead of the curve? The fact that BFL has a proven chip design, combined with their innovations in form factor and node size means that they will be hard to beat moving forward."
