China's NVIDIA Chip Replacement Plan Hits HBM Memory Snag 2026

China's ambition to replace NVIDIA chips with domestic alternatives has hit a major roadblock: HBM memory. The high-bandwidth memory that sits alongside AI processors is exposing the limits of China's self-sufficiency drive.

For years, Beijing has pushed for the substitution of NVIDIA chips with homegrown accelerators. Companies like Huawei, Cambricon, MetaX, and Iluvatar CoreX have developed products to fill the gap left by U.S. restrictions. But reducing dependence isn't just about the processor—it's about the entire component ecosystem.

Why HBM Memory Is Critical for AI Chips

High Bandwidth Memory (HBM) is a type of DRAM made of vertically stacked chips connected to move massive amounts of data at high speeds. In AI accelerators, it sits very close to the processor and is essential for feeding data-hungry workloads.

Without HBM, even the most advanced AI chip can't perform at its peak. And that's the problem: China's domestic chipmakers still rely heavily on foreign HBM suppliers, primarily from South Korea and the United States.

Prices Are Already Climbing

The supply chain strain is showing up in prices. According to Reuters, Huawei has raised the indicated price of its Ascend 950DT to over 250,000 yuan (about $37,000). That's a 20% to 50% increase compared to prices quoted to customers just two months earlier, depending on contract terms.

Cambricon has also reportedly hiked prices for its upcoming 690 generation by 20% to 30%, even though it hasn't officially launched. MetaX and Iluvatar CoreX have applied similar increases. These hikes reflect the rising cost and scarcity of HBM memory.

The HBM Bottleneck: A Supply Chain Reality Check

China's domestic AI chip industry has made impressive strides in designing processors. But HBM is a different story. The technology requires advanced packaging capabilities and specialized manufacturing that few companies possess.

Global HBM leaders like SK Hynix, Samsung, and Micron dominate the market. Chinese firms like CXMT are trying to catch up, but they lag in both yield and capacity. Until domestic HBM production matures, Chinese AI chipmakers will remain vulnerable to supply disruptions and price volatility.

• HBM is essential for AI accelerator performance, and China still depends on foreign suppliers.
• Prices are rising: Huawei's Ascend 950DT now costs over $37,000, up 20-50% in two months.
• Cambricon, MetaX, and Iluvatar CoreX have also raised prices by 20-30%.
• Domestic HBM alternatives like CXMT are still years behind in scale and yield.
• The supply chain remains global, limiting China's ability to fully decouple from foreign technology.

What This Means for China's AI Ambitions

China's AI chip strategy is not just about designing faster processors. It's about building a complete domestic supply chain. HBM is a glaring weak point.

The price increases could slow adoption of domestic AI chips among Chinese cloud providers and AI startups. Higher costs may make NVIDIA's restricted chips—still available through gray markets—more attractive, undermining the substitution effort.

Moreover, the HBM bottleneck highlights how interconnected the global semiconductor industry remains. Even as China invests billions in self-sufficiency, some technologies are too complex and capital-intensive to replicate quickly.

What to Watch Next

All eyes are on China's domestic HBM efforts. CXMT and other players are ramping up R&D, but progress will be measured in years, not months.

Also, keep an eye on U.S. export controls. Any tightening of HBM-related restrictions could exacerbate the situation. For now, China's NVIDIA chip replacement plan faces a critical test: can it solve the HBM memory problem before it derails the entire strategy?
