Bitcoin mining hardware
In the early bitcoin era only CPU and GPU is used for solo and pooled bitcoin mining. The most effective and popular hardware for bitcoin mining in these days was AMD Radeon video cards. The graphical processing unit (GPU) able to hash data up to 100 times faster and consume much less power per one solved hash.
In the first months of 2011, new type of custom bitcoin mining equipment was created: bitcoin mining devices based on field-programmable gate array (FPGA) chips with USB connection to computer.
Today's if you want mine bitcoin you need special ASIC mining hardware. Application-specific integrated circuit (ASIC) miners mine at very high speeds and consuming much less power than FPGA or GPU mining hardware. The most powerful ASIC mining hardware now manufactured by AntMiner.
