Memory Giants Gain Pricing Power Over AI Firms as DDR5 RDIMMs Beat HBM Profitability, Setting Stage for 2027 Hikes - Wccftech

The semiconductor industry is undergoing profound transformation driven by rapid AI development. Recent developments show memory chip giants gaining stronger pricing power over AI firms, primarily due... Read original →

DDR5 RDIMMs overtaking HBM in profitability signals a strategic pivot in AI hardware—from raw performance to cost-per-watt efficiency. This shift forces CPU/GPU architects at AMD and Intel to accelerate CXL integration, reducing reliance on power-hungry HBM stacks. Geopolitically, DDR5’s diversified supply chain—spanning the U.S., Japan, and mainland China—offers AI firms a safer alternative to HBM’s Korea/Taiwan, China-centric fabrication, especially under tightening U.S.-EU export controls. In response, Samsung and SK hynix may slow HBM3E capacity expansion and push hybrid memory bundles, while Micron leverages its low-power RDIMM edge to infiltrate NVIDIA’s GB200 platforms. Within 18 months, tiered memory architectures will become standard in AI servers, redirecting TSMC’s CoWoS capacity toward logic dies rather than HBM stacking—easing packaging bottlenecks. Price hikes in 2027 are inevitable, but only AI chipmakers who’ve already rebalanced their BOMs will retain margin control.
