Bitmain's 5nm mining chip may be the world's first packaged 5nm test-level chip

Wu said that blockchain has learned from people close to TSMC that Bitmain's 5nm mining chip may be the world's first packaged 5nm test-level chip. It is reported that the yield rate of TSMC's 5nm test chip has reached an average of 80%, and it will be put into large-scale mass production in the first half of 2020. The performance improvement is between 7% and 15% compared with 7nm. Previously, Canaan won the first place in the world's first 7nm test-level chip. The design and packaging of mining machine chips are relatively simple, so it is easy to become the "first", but in terms of production capacity, TSMC will still give priority to major customers such as Apple, HiSilicon, and Qualcomm.
