Antminer R4: The Bitcoin Miner Perfect for the Home
BitMain’s latest and most exclusive Bitcoin miner to date. Although the R4 has only just been made public, we’re already able to give our feedback and outline the most crucial information.

Hash Rate
The R4 will hash at 8.6 Ths (8.6 TeraHash per second), making it one of the fastest Bitcoin miners around it’s not as fast as the S9, but it is as efficiency is equal and it has to be one of if not the quietest miners we have come across (about the same as a quiet fridge)!

The R4 is very efficient, at 0.098 J/GHs it is on par with the S9 as the most energy efficient Bitcoin Mining Hardware on the market! To quote Bitmain:
The Bitmain BM1387 asic chip is built with TSMCs 16nm Fin FET technology and delivers a record-breaking 0.098 J per Ghs which makes it the world’s most efficient Bitcoin mining chip on the consumer market. The Antminer R4 is so efficient due to the use of the 126 x BM1387 Chips, which are 16nm. BitFury was the first company on the scene to release the 16nm chip.
