AMD is in talks to buy Xilinx in a deal that may be valued at $30 billion, people familiar said. A combination would give AMD more heft to break Intel's grip on the market for data-center components and expand its footprint in 5G and AI. It would face little U.S. regulatory pushback, but winning over China may be tougher, Bloomberg Intelligence said. Xilinx jumped 17% premarket, AMD slipped 4%.
