Samsung gains ground in Nvidia HBM4 tests as AI memory supply race tightens

Samsung Electronics has emerged as a strong contender in Nvidia’s next-generation AI memory supply race after its sixth-generation high bandwidth memory, known as HBM4, received favorable late-stage test feedback focused on speed and power efficiency, according to local semiconductor industry sources. Nvidia engineers reportedly reviewed Samsung’s progress on HBM4 system-in-package, or SiP, testing, a critical step that evaluates whether multiple chips can operate stably when integrated into a s
