AMD acquires ZT Systems for $4.9 billion to boost its position in the AI race and expand its expertise in AI systems design. The deal includes a mix of cash and stock, with a contingent payment of up to $400 million. ZT Systems provides compute design and infrastructure for AI, cloud, and general purpose computing and has previously worked with chipmakers such as Nvidia and Intel. This acquisition will help AMD sell more of its chips and systems to customers as AI systems become more complex.
