Samsung Set to Begin HBM4 Production for Nvidia and AMD

Samsung Electronics is preparing to begin mass production of its next-generation high-bandwidth memory chips, known as HBM4, as early as next month, according to a source familiar with the matter cited by Reuters. The advanced memory chips are expected to be supplied primarily to Nvidia, a key customer driving global demand for high-performance semiconductors used in artificial intelligence, data centers, and high-end computing applications.

While the source did not disclose the volume of HBM4 chips Samsung plans to deliver to Nvidia, the move itself signals a major milestone in the global memory chip race. HBM4 represents the latest evolution in high-bandwidth memory technology, offering faster data transfer speeds, improved power efficiency, and higher capacity compared to previous generations. These features are especially critical for AI accelerators and GPUs, where memory performance can directly impact overall system efficiency.

A spokesperson for Samsung Electronics declined to comment on the report, maintaining the company’s usual stance of not discussing specific customer relationships or production schedules. However, local media reports have added further context. South Korea’s Korea Economic Daily reported that Samsung has successfully passed qualification tests for its HBM4 chips with both Nvidia and AMD, citing unnamed sources within the semiconductor industry. According to the report, shipments to these major chip designers are expected to begin next month.

If confirmed, this development would strengthen Samsung’s position in the competitive HBM market, where it faces intense rivalry from SK Hynix and Micron. With AI-driven demand for advanced memory surging worldwide, securing supply agreements with industry leaders such as Nvidia and AMD could provide Samsung with a significant competitive advantage.

The timing is also notable as global chipmakers race to secure stable supplies of next-generation memory to support increasingly complex AI workloads. Samsung’s potential early entry into HBM4 production may help it capture greater market share while reinforcing its role as a critical supplier in the rapidly expanding AI and semiconductor ecosystem.
