QWhat is the BitForce SC?
The BitForce SC processor is the result of our long term development of a multipurpose SHA256 hashing engine in full custom ASIC. The BitForce SC achieves an exponential increase in verification performance and power draw efficiency by using the latest semiconductor manufacture technology. Why ASIC? ASIC is the final word in processor design. There is no next step threatening to change everything. This makes it the first stable ground for hardware investment as compared to prior stages which experienced unpredictable and violent change as technology moved up the ladder from CPU to GPU, then FPGA and sASIC / Hardcopy. Pure custom ASIC is the end of the line. With ASIC comes not only a phenomenal performance increase, but also a stability in the rate of performance increase. Yes, improvements in ASIC will continue to occur, but only at the stable & predictable rate as followed by the rest of the semiconductor industry and not sudden exponential growth like the jump into ASIC itself. The volatile risk of hardware investment is now behind us and for the first time, high speed hash verification performance can be had in a convenient USB stick or clustered in a compact, yet face meltingly fast rack mount system without the traditional burden of power, heat or space constraints.
QHey, what the heck? Why'd you come out with this after I just bought a bunch of Singles. I'm going to be left behind!
We hear you loud and clear and we promise to stand by our customers through this technology change with an all inclusive trade in policy designed to protect the dollar value of your existing hardware. Upon release of BitForce SC based Singles & Mini Rigs, all previous generation BitForce products will enjoy a full 100% trade in value when used towards the purchase of the newer generation replacements. This means your current device is protected from depreciation through this evolution in technology. This buy back offer is good for all previous generation BitForce units whether purchased directly from us or from a third party. Full terms of our obsolescence guarantee will be forthcoming. Having said this, it's also important to point out that current generation products enjoy strong relative hashing power today and that will continue to make them profitable up to and through the point of ASIC market penetration when they can be traded in.
QWhy should I buy a Mini Rig or Single if the BitForce SC is coming out?
It depends on the lead time difference between your product and the availability of the BitForce SC. As long as there is a sufficient gap in between the delivery of the two then it makes sense to enjoy the strong performance of current gen products before network difficulty increases as a result of ASIC market penetration. At that time, your units can be traded in towards an upgrade to equivalent BitForce SC based replacements.
QWhen will the BitForce SC be available, and how fast are they?
Our ASIC based products ranging from 4.5 GH/s to 1,500 GH/s are currently scheduled for availability in February, 2013.
QCan these devices be used for anything else like password cracking?
No, their function is limited to high speed encryption validation in the specific double step sha256 protocol. It's not useful for any purpose related to rainbow tables or password recovery.
