The latest news coming in from China is that mining giant Bitmain is working on an Ethereum ASIC miner, the purported Antminer F3. Bitmain’s rumored F3 Ethereum miner would pack 3 motherboards with 6 ASICs per motherboard, as well as 32 x 1GB DDR3 memory chips that would make for a very power efficient, but incredibly powerful Ethereum ASIC miner. This would put GPU mining for Ethereum out of business, almost overnight. Bitmain is reportedly meeting with a few manufacturers in Taiwan, so you can be sure that they’re talking to TSMC and others in order to see how many chips they can get their hands-on. The new ETH ASIC chips will begin production later this month, with the ASICs hitting 200-200MH/s and this could be even better with final hardware. We would be looking at between $2500 and $3000 for the Atminer F3 Ethereum ASIC miner, which is not too bad at all considering the purported 200-220MH/s mining power.
