GMO to Release World's First 7nm Bitcoin Mining Card

Japan's GMO Internet Group officially announced the June 7th release of its new Bitcoin mining card- "GMO Miner B2", marking a new era of powerful, energy-efficient processing units as the world's first 7nm consumer mining card.

The current, most popular Bitcoin mining card, the Antminer S9, utilizes Bitmain's proprietary BM1387 16nm chip to provide 14 TH worth of hashing power.

The 10nm DragonMint T1 features a Samsung made T1558 chip pushing 16TH with the addition of ASIC boost for greater power efficiency.

Though these chips provided Samsung with a significant revenue boost, they only show incremental performance gains over their last generation counterparts.

The upcoming 7nm chips are estimated to contain 20+ billion transistors and will offer up to a 40% performance gain, or over 65% power reduction compared to their 16nm rivals.

GMO appears to have surpassed competitors when it comes to 7nm dyes.

This will undoubtedly affect the chip maker's 7nm development schedule unless an unforeseen breakthrough allows them to leapfrog the 10nm lithography.

Transitioning to 7nm introduced an entire suite of technical manufacturing issues that accompany the move from deep ultraviolet immersion lithography to extreme UV. The jump in dye size requires a jump in emitted laser wavelength, moving from 193 nm down to 13.5 nm.

GMO's first generation of 7nm chips anticipates providing the company with a substantial advantage for the latest production of mining cards.

GMO will host a customer information session in Shibuya, Tokyo, on June 6th and the new units are expected to be shipped at the end of October 2018.Cover Photo by Alexandre Debiève on Unsplash.
