The demand for mining equipment has become one of the reasons for the enormous profit growth both of AMD video cards producer and of Samsung chips manufacturer.

Cryptocurrency mining demand accounted for as much as 10% of AMD's first-quarter revenue this year, AMD reported.

“The strength in Radeon products was driven by both gaming and blockchain demand. We believe blockchain was approximately 10% of AMD revenue in Q1 2018,” said AMD’s CFO Devinder Kumar on the earnings call.

AMD's profit for the I quarter increased by 40% year-on-year to $1.65 billion.

South Korean Samsung also reported an increase in revenue due to the sale of mining chips. Samsung's operating profit in the I quarter increased to 15.64 trillion Korean won ($14.45 billion).

"In the semiconductor business, the earning increases significantly year over year thanks to favorable market conditions driven by strong demands in server and graphic card memories as well as earning improvement in both the System LSI and Foundry businesses led by an increasing demand of chips used in flagship smartphones and cryptocurrency mining," said Robert Yi, executive vice president of investor relations at Samsung, during a telephone press conference dedicated to the disclosure of financial results.

In late January, Samsung confirmed the information that it started producing ASIC chips for cryptocurrency mining. Later it was disclosed that largest buyer of Samsung's chips is Chinese manufacturer of mining equipment Halong Mining, whose DragonMint T1 miner is said to be the most effective to date bitcoin miner in the market, superior in performance to even the most popular Antminer S9 from the largest mining equipment manufacturer Bitmain.
