AMD today disclosed that it had found stolen graphics IP posted online, with reports to indicate that the information pertains to source code for Big Navi and Arden GPUs.

Website Torrentfreak claims to have contacted the hacker responsible, who claims the information is worth $100 million and is seeking bidders. The hacker claims the unencrypted information was found in a computer/server hacked via exploits.

AMD has filed 'at least two DCMA notices' against Github repos that contained the stolen source code for the company's Navi 10, Navi 21, and Arden GPUs. The latter powers Microsoft's forthcoming Xbox Series X consoles, while Navi 21 is thought to be the design for the RDNA 2 'Big Navi' GPUs.

Github has since removed the repositories, but there are other sources that still host the leaked information.

AMD said that in December 2019, the company was contacted by someone who claimed to have test files related to a subset of its current and future graphics products, some of which were recently posted online, but have since been taken down.

"While we are aware the perpetrator has additional files that have not been made public, we believe the stolen graphics IP is not core to the competitiveness or security of our graphics products. We are not aware of the perpetrator possessing any other AMD IP.

We are working closely with law enforcement officials and other experts as a part of an ongoing criminal investigation," AMD said.
