It seems that Bitmain is not over with new releases of ASIC miners, this time however the release may be only for the Asian market (now available on the English website as well) in the form of the new Antminer B3 ASIC miner for Bytom (BTM). The new Bitmain Antminer B3 is supposed to offer 780 H/s mining hashrate with 360 Watts of power usage and cost about $2700 USD with shipments starting tomorrow for a limited number of units (2500 only). What is more interesting here is that Bytom (BTM) is just launching their main network later today and mining will be just starting, so having and ASIC miner ready for pretty much the start of a crypto coin is something new. Then again Bytom has listed Bitmain as one of their partners on the website of the project, so that may actually not be of a much surprise.
Update: The Bytom (BTM) main network has launched and the coin can be mined from within the Bytom wallet with CPU only for the moment, or by using any of the Bitmain B3 ASIC miners that are apparently already on the network, no GPU mining is possible for the moment as there are no AMD/Nvidia GPU miners currently available and with ASICs already available CPU mining might not be worth it and the same may go for GPU mining as well (depends on performance).
