Follow the link silly.
Butterfly Labs reveals final performance specifications for it's revolutionary ASIC hardware.
BitForce Jalapeno - 4.5gh/s @ 4.5w
BitForce Single SC - 60 GH/s @ 60w
BitForce MiniRig SC - 1,500 GH/s @ 1,500w
Power figures are +/- 10% of those listed while we finish optimizing our power subsystem.
NEW An as yet named 'Little Single' device which will hash at a rate of 30 GH/s and cost USD $649.00.
You may notice that these performance figures exceed that of our previously published specification by approximately 50%. Our intention was to eventually over deliver while also being conservative during development. We had planned to reserve this performance increase for a future firmware update and was one method we planned to use to protect our customers in the event of a price war. However, due to the maturity of our development and competition in the market, we felt it was time to clarify what customers will actually receive both in speed and particularly in power consumption so they can properly evaluate their options and make good decisions. We hope it's now easier to understand the closed lip approach of our ASIC line product development.
A pledge to our customers: Butterfly Labs has always been committed to our customers. With the transition to ASIC from FPGA, we offered a 100% buyback program on the purchase price of your FPGA units towards the purchase of one of our ASIC units. This is an offer currently unmatched by any other manufacturer. People have asked why would we do this? We do this because our mission is to stand behind our customers and preserve the value of their hardware investment through all market changes, now and in the future. Simply put, you can count on us to protect your mining investment.
In summary, all current orders are automatically 4.5 GH/s - 60 GH/s or 1.5 TH/s devices. You need do nothing, just wait for delivery.
Our Value pledge: As always, our focus has been on offering the most competitive product, both in terms of initial price but also the most competitive TCO in the industry. Our current power consumption targets for our first generation ASIC products are approximately 1 GH per watt, far and away the lowest power consuming units available at any price. Not only will our products perform faster than any other product currently available, it will also cost less to run now and in the future. As with our FPGA products, when the time comes for our second generation ASIC products, we will not forget our customers and will make every effort to transition you, the customer, to the second generation ASIC as easily, quickly and in the most cost effective manner as possible.
