OAKLAND, Calif. (Reuters) -U.S. chip maker Nvidia Corp is offering a new advanced chip in China that meets recent export control rules aimed at keeping cutting-edge technology out of China’s hands, the company confirmed on Monday.

Nvidia responded to Reuters’ reporting that Chinese computer sellers are advertising products with the new chip.

The chip, called the A800, represents the first reported effort by a U.S. semiconductor company to create advanced processors for China that follow new U.S. trade rules. Nvidia has said the export limitations could cost it hundreds of millions of dollars in revenue.

U.S. regulations set in early October effectively banned export of advanced microchips and equipment to produce advanced chips by Chinese chipmakers, part of an effort to hobble China’s semiconductor industry and in turn the military.

In late August, Nvidia and Advanced Micro Devices Inc both said that their advanced chips, including Nvidia’s data center chip A100, were added to the export control list by the U.S. Commerce Department. The Nvidia A800 can be used in place of the A100 and both are GPUs, or graphics processing units.

Such advanced chips can cost thousands of dollars each.

“The Nvidia A800 GPU, which went into production in Q3, is another alternative product to the Nvidia A100 GPU for customers in China. The A800 meets the U.S. Government’s clear test for reduced export control and cannot be programmed to exceed it,” a Nvidia spokesperson said in a statement to Reuters.

Nvidia declined comment on whether it consulted the Commerce Department about the new chip. A Commerce Department spokesperson declined to comment.

At least two Chinese websites by major server makers offer the A800 chip in their products. One of those products previously used the A100 chip in promotional material.

A distributor website in China detailed the specifications of the A800. A comparison of the chip capabilities with the A100 shows that the chip-to-chip data transfer rate is 400 gigabytes per second on the new chip, down from 600 gigabytes per second on the A100. The new rules restrict rates of 600 gigabytes per second and up.

“The A800 looks to be a repackaged A100 GPU designed to avoid the recent Commerce Department trade restrictions,” said Wayne Lam, an analyst at CCS Insight, basing his comments on the specs shared by Reuters, and noting that eight is a lucky number in China.

“China is a significant market for Nvidia and it makes ample business sense to reconfigure your product to avoid trade restrictions,” said Lam.

Lam said the chip-to-chip communications abilities of the A800 represented a clear performance downgrade for a data center where thousands of chips are used together.

Major Chinese server makers Inspur and H3C which offer servers with the new chips did not respond to requests for comment. Neither did chip distributor OmniSky, which posted the A800 specs online.

Nvidia has said that about $400 million worth of chip sales to China could be impacted in its fiscal third quarter ended in October due to the limits on high-end chips. Having a replacement chip could help lessen the financial blow. The company is to report quarterly results on Nov. 16.
