Intel Unveils Bonanza Mining Chip for Efficient Bitcoin Mining at ISSCC 2022


Intel was preparing to showcase its first Bitcoin mining ASIC at ISSCC 2022 and as the event kicked off on February 20, Intel revealed more details about the Bonanza mine ASIC, as well as its Bonanza mining system – a standalone computer, which features 300 Bonanza Mine ASICs to deliver 40 terahashes per second (THash/s) of performance while consuming 3,600W of power. The chipmaker’s presentation was devoted to the first-generation Bonanza Mine ASIC codenamed BMZ1, as well as a system based on them, however, the company is already ready to ship a second-generation product to customers. , the details of which have yet to be revealed. by Intel.

While this sounds like a barrage of numbers to non-miners, it’s worth noting that Intel’s performance numbers for the BMZ1 don’t quite match Bitmain’s competition, as noted by CryptoAge. But as mentioned, the company has already started shipping customers a second-generation product codenamed BMZ2.

According to a CoinTelegraph report, Bonanza Mine System incorporates four hash boards, an Intel FPGA control unit, four fans, and a programmable power supply. An FPGA is a “field-programmable” integrated circuit that offers customers the ability to reconfigure the hardware to meet specific use-case requirements – in this case, Bitcoin mining – after the manufacturing process.

Intel’s patent for “High Performance Bitcoin Mining” was filed in November 2018, and it offered a 15% reduction in overall power consumption. At the time, Intel executives expressed confidence in competing with established companies such as Bitmain, MicroBT, and Nvidia.

Intel’s new mining chips, the BMZ2, will be available later this year with US power company GRIID Infrastructure, crypto-mining company Argo Blockchain and Jack Dorsey-led Block among the first customers in line to receive the first batch of mining chips.

Now, based on the information revealed by Intel so far, the second-generation BTC miner will be able to deliver a balanced performance of 40.4 THash/s while consuming 2293W of power, recording low power consumption. energy of 56.97 joules per THash. Compared to Bitmain hardware, the Bitcoin ASIC miner Antminer S19j consumes 3,100W to deliver up to 90 THash/s at room temperature, resulting in an efficiency of 34.5 joules per THash.

As a report by Tom’s Hardware points out, Bitcoin mining company GRIID’s supply agreement with Intel features a host of redactions to protect sensitive information, but still reveals references to Intel’s reference design materials that are essentially customer-facing documents to use as a guide during onboarding. the Bonanza mine integrates its own custom systems.

This implies that Intel will supply the silicon to some of its customers, who will then create their own systems. It also bodes well for Jack Dorsey’s plans for Block, which he says will create a “custom, open-source, silicon-based bitcoin mining system for individuals and businesses around the world.”
