Samsung just locked down a major win in the AI memory wars. The chipmaker signed a partnership with AMD to supply its industry-first HBM4 memory for AMD's upcoming Instinct MI455X GPU and next-generation EPYC processors, according to an announcement from Samsung's Pyeongtaek facility. The deal positions Samsung as the primary memory partner for AMD's next wave of AI infrastructure - a direct challenge to the SK Hynix-Nvidia alliance that's dominated the space.
Samsung and AMD just drew a new battle line in the AI infrastructure arms race. The two companies inked a memorandum of understanding that makes Samsung the primary supplier of cutting-edge HBM4 memory for AMD's next-generation AI accelerators, marking a significant shift in the competitive landscape where Nvidia and SK Hynix have dominated.
The signing ceremony at Samsung's Pyeongtaek chip manufacturing complex brought together AMD Chair and CEO Dr. Lisa Su and Samsung Vice Chairman Young Hyun Jun, signaling the strategic weight both companies are placing on this partnership.
"Samsung and AMD share a commitment to advancing AI computing, and this agreement reflects the growing scope of our collaboration," Jun told attendees at the Pyeongtaek facility. "From industry-leading HBM4 and next-generation memory architectures to cutting-edge foundry and advanced packaging, Samsung is uniquely positioned to deliver unrivaled turnkey capabilities that support AMD's evolving AI roadmap."
The technical specs reveal why this matters. Samsung's HBM4 - the first to hit mass production industry-wide - runs on the company's most advanced 6th-generation 10-nanometer DRAM process paired with a 4nm logic base die. The result: processing speeds hitting 13 gigabits per second with maximum bandwidth of 3.3 terabytes per second, exceeding current industry standards.
