NVIDIA and SK Hynix Lock Down HBM4/5 Roadmap, Cementing Vera Rubin Supply Chain
NVIDIA and SK Hynix sign a multi-year agreement to co-define HBM4 production and HBM5 pre-research for Vera Rubin GPUs. Samsung also enters HBM4 supply as a second source. The deal elevates SK Hynix from vendor to co-developer, potentially creating a de facto memory standard barrier that marginalizes Micron and others.
Global GPU Shortage to Persist Until 2027: Core Bottleneck for AI Infrastructure Expansion
Global GPU shortage expected to extend to 2027-2028, rooted in AI data center demand surge, constrained HBM production, CoWoS packaging tightness, and geopolitical risks. NVIDIA Rubin's mass production hindered (target reduced from 2M to 1.5M units), with Blackwell capturing 71% of high-end GPU shipments in 2026. Consumer RTX 5080/5070 Ti priced $200-$500 above MSRP, enterprise AI infrastructure procurement cycles will further extend.
NVIDIA Rubin Delayed, Blackwell to Account for 71% of High-End GPU Shipments in 2026
NVIDIA Rubin GPU production target lowered from 2M to 1.5M units due to HBM4 memory validation delays. TrendForce data shows Blackwell share rising from 61% to 71% in 2026, consolidating dominance. Micron exits Rubin HBM4 supply chain, SK hynix to hold 70% share. Analysts maintain overweight ratings, viewing impact as limited. Rubin delay may extend SK hynix's HBM3E market dominance.
NVIDIA Rubin Era: 1.8kW GPU TDP and Mandatory Liquid Cooling Reshape Data Centers
NVIDIA's mandatory liquid cooling is a landmark event in AI infrastructure 'qualitative change' of physical form. When chip power exceeds 1.8kW, air cooling physical limits are breached, the entire data center industry chain—from power architecture, cooling systems to building structure—must be redesigned. This isn't technology upgrade but paradigm shift.
AMD and Samsung Deepen HBM4 and CXL Memory Technology Collaboration
AMD and Samsung expanded strategic collaboration to co-develop next-gen AI memory solutions, focusing on HBM4 and CXL technologies. The partnership will optimize memory controllers, PHY layers and packaging to enhance AI computing platform performance. Joint efforts will advance HBM4 standardization and explore CXL applications in memory pooling.
AMD and Samsung Deepen Collaboration, Locking HBM4 Supply and Exploring Foundry Partnership
AMD and Samsung signed an MOU, designating Samsung as the primary HBM4 supplier for the next-gen Instinct MI455X GPU and collaborating on DDR5 memory optimized for 6th Gen EPYC CPUs. The companies will also explore opportunities for Samsung to provide foundry services for future AMD products.
Samsung and AMD Deepen AI Hardware Collaboration with HBM4 Supply and Foundry Services
Samsung will be the primary HBM4 supplier for AMD's next-gen MI455X GPU, delivering 13Gbps bandwidth memory. The partners will also develop DDR5 solutions for 6th-gen EPYC CPUs and explore Samsung's foundry services for future AMD products.
Samsung Unveils HBM4E and Hybrid Copper Bonding for AI Infrastructure
Samsung announced HBM4 mass production and showcased next-gen HBM4E with 4TB/s bandwidth at GTC 2026. Hybrid copper bonding enables 16+ layers with 20% lower thermal resistance. Also launched SOCAMM2 memory and PCIe 6.0 SSD for NVIDIA AI infrastructure.
NVIDIA and SK hynix Co-Architect Next-Gen Memory for AI Factories, Locking HBM4 to Vera Rubin
NVIDIA and SK hynix announce a multi-year tech partnership to co-develop next-gen memory for Vera Rubin, RTX Spark, and Jetson Thor. Separately, SK Telecom deploys a gigawatt-scale AI cloud using the full DGX stack, targeting 2027. This elevates SK hynix from supplier to co-architect, strengthening NVIDIA's lock-in on HBM and the AI ecosystem.
