Samsung has developed its first HBM4 chip

After years of lagging behind Micron and SK Hynix in the high-speed memory segment, Samsung has unveiled its first HBM4 chip at the Semiconductor Exhibition (SEDEX) 2025 in South Korea. This is an important step that should help the South Korean giant regain lost ground and strengthen its influence in the market for advanced artificial intelligence solutions.
SEDEX 2025 is taking place from October 22 to 24 in Seoul. It was there that Samsung officially revealed its sixth generation of high-speed memory — HBM4 (High Bandwidth Memory 4). These chips are used in AI gas pedals from companies like AMD and Nvidia, which power the generative algorithms of the world’s biggest IT companies.
A lot depends on how well the new chip performs. If Nvidia chooses Samsung’s HBM4, the company could generate billions of dollars in operating profit every quarter for years to come.

Samsung’s main competitor — SK Hynix — has also finalized the development of its HBM4 chips and demonstrated them at the same exhibition. According to media reports, SK Hynix is already in advanced talks with Nvidia for a large shipment. All three manufacturers — Micron, SK Hynix and Samsung — have already sent their HBM4 samples to Nvidia for testing, after which the company will decide who to entrust the contract to.
Samsung’s HBM4 is manufactured using the sixth-generation 10nm process (1c), which is considered more advanced than the fifth-generation 10nm process (1b) used in SK Hynix’s solutions. Theoretically, Samsung’s chips should deliver better performance, but final conclusions can only be drawn once Nvidia’s testing begins.
