Advanced Micro Devices (AMD) shares fell for a second-straight day after the firm's new Ryzen line of desktop processors disappointed gamers.

"The [Ryzen] 1800X lags behind its Intel (INTC) counterparts in gaming, regardless of whether it's running at the same clock speed or higher," Mark Walton wrote in technology review site Ars Technica on Thursday.

PCWorld, PC Gamer also criticized the new processors for poor gaming performance.

Shares of AMD traded more than 5.5 percent lower Friday after falling 7 percent Thursday. Intel shares traded nearly 0.2 percent lower Friday.

John Taylor, a spokesman for Advanced Micro Devices and vice president at Worldwide Marketing, told CNBC: "There are a few gaming oriented sites that have expressed some disappointment over gaming performance at low resolution. This is a matter of optimization by those games on Ryzen. The CPU performance shines through strongly in every CPU test reviewers have run."

AMD released its Ryzen 7 lineup Thursday with 3 models: an 1800x, 1700x, and 1700 whose prices range from $329 to $499. The semiconductor company announced the product line back in December.

Outside of gaming, Ars Technica's Walton said, that "for the most part, Ryzen is highly competitive with Intel's eight-core i7-6900K."

On Jan. 31, the company posted a lower-than-expected fourth-quarter loss of 1 cent per share on revenue of $1.11 billion. Analysts polled by Thomson Reuters expected a loss of 2 cents per share on revenue of $1.07 billion.

The company gave high expectations for the first quarter, estimating an 18 percent boost in revenue.
