Why do ASIC mining hardware manufacturers give their products names like Klondike and GoldStrike? It’s because bitcoin mining is like a gold rush. People are rushing to stake a claim to a limited resource, and they need the best equipment that they can to mine it.
After GPUs and FPGAs, the rush is on to produce ASIC-based miners that are faster and more power efficient than their predecessors. The market is flooded with vendors promising the next, greatest ASIC hardware. But all that glitters is not gold. Here is a roundup of what’s on offer (and what’s actually shipping, which isn’t much). Let s start with one of the first companies to ship an ASIC miner: Avalon. This firm, which began shipping in January, designed its own ASIC chip, based on a 110 nm process. First-generation units operated at around 68 GH/sec, and batch three of these units, selling for around BTC72, guarantees at least 63 GH/sec, says the company.
Avalon s strength was also its biggest drawback: it was able to getHigh performance 28 nm ASIC mining chip Hashing Output: Up to 750 GH/s (overclocked) Hashing Output: 400 GH/s (nominal) Power Consumption at the chip: 0.65 Watt per GH/sec (+/- 20%) Die has built in thermal controls that allow the chip to pushed to the edge without damaging cores Designed to be under-clocked for greater efficiency, and overclocked for greater performance 4 cores, each one 9mmx9mm, total of 324 square mm Each die has 96 independent cores, a PLL and a tempMore and more people are getting involved with Bitcoins. More and more people are becoming interested in how to mine by themselves. Everybody can do Bitcoin mining by running software with specialized hardware. In the early days it was possible to find a new block using your computer’s CPU.
As an increasing number of people started mining, the difficulty of finding new blocks increased greatly to the point where the only cost-effective method of mining today is using specialized hardware. There are several people and teams all over the world who are busy with developing the finest mining hardware. The fastest USB miner in the world at this moment is the bi•fury 5GH USB ASIC Bitcoin Miner. Bitcoin Magazine spoke with network engineer and Bitcoin enthusiast Filip Pawczyński from Poland. He runs IT company FPITM and introduced the bi•fury in November. Christien Havranek: What exactly are you doing in the world of Bitcoins and with the hardware? And since when?

Sorry aboutHashFast engineers, continuing the bringup process of HashFast’s GN chip and module, achieved our stated commercial performance today – exceeding 400 GH/s for a single GN ASIC by operating all four die on the GN device at a hash clock rate of 550 Mhz. Our engineers then proceeded to increase hash clock-rate, achieving performance in excess of 500 GH/s while easily staying within the specified timing constraints for the ASIC. Our conservative design margins allow for still further increases, and we expect to see even greater performance over the coming days. This milestone represents a breakthrough in Bitcoin mining technology and is several times faster than existing competitive offerings. We have commenced volume production of mining systems for shipment to our early adopters over the coming weeks.
Stay tuned for further performanceBy Joel Hruska on January 1, 2014 at 10:01 am Comment A group of Bitcoin miners that bought into the hype surrounding one particular manufacturer, HashFast, are reportedly examining legal options after the company repeatedly failed to deliver on its hardware and is only now beginning to ship products promised in October (and refusing to give full refunds). The problems illustrate many of the teething problems within the Bitcoin network, as well as the fundamental difficulty of making money by mining the cryptocurrency. The Bitcoin mining network fundamentally transformed in two key ways in 2013. First, the difficulty of mining Bitcoins exploded in the back half of the year, driving profits through the floor in terms of earnings per megahash.
Second, the value of a BTC has skyrocketed, crashed, and then continued towards recovery. These two events are logically connected — a huge jump in mining difficulty should increase the value of one BTC, if the currency is to hold any valueThere’s more than one way to make money from the Bitcoin craze, which has seen the value of the digital currency increase more than six-fold over the past few months. You can do it the old-fashioned way: buying low and selling high. But for the sophisticated digital-currency investor, there’s a whole other world of Bitcoin speculation: the Bitcoin mining rig. Like the currency itself, this strangely lucrative game is heating up — in a big way. One mining rig — available for preorder at a cost of about $1,800 in February — is now selling for more than $22,000 on eBay.
And it hasn’t even shipped yet. Over the past year, a handful of companies have raced to build a new generation of computers that are specifically designed to mint digital money, and many speculators across the Bitcoin world are dying to get their hands on the latest hardware. This week, one of these companies, Butterfly Labs, is finally shipping its first custom-designed machines, six months behind schedule. If Bitcoins.
