TrendForce reports that the expansion of Artificial Intelligence infrastructure is continuing to drive demand for GPUs, setting the stage for NVIDIA’s upcoming Rubin platform to play a pivotal role in accelerating HBM4 adoption once mass production starts. As data center operators and cloud providers scale Artificial Intelligence workloads, the need for higher performance and bandwidth in memory technologies is focusing industry attention on the transition to HBM4.
The three major memory manufacturers, Samsung, SK hynix, and Micron, are described as being in the final stages of HBM4 validation, with completion anticipated by 2Q26. This timeline positions all three companies to be ready to support NVIDIA Rubin when it enters mass production, aligning memory supply availability with the expected ramp in next generation GPU deployments.
Samsung, backed by what is characterized as strong product stability, is projected to secure certification first, ahead of its rivals. SK hynix and Micron are expected to achieve certification shortly after Samsung, resulting in a three supplier ecosystem for NVIDIA’s HBM4. This multi vendor setup is poised to shape NVIDIA’s HBM4 supply landscape by diversifying sourcing options and potentially improving resilience and competitiveness across the high bandwidth memory market.
