China’s Chip Strategy: Loongson’s 3A6000 and the Shift Toward Mature-Node Power

Even if these processors do not yet compete head‑to‑head with the latest chips from Intel or AMD, large‑scale deployment creates a foundation for:

• A domestic installed base of CPUs
• Software and operating‑system compatibility
• Procurement channels for local vendors
• Long‑term ecosystem development

That ecosystem is critical for reducing reliance on foreign computing platforms.

Richard Chang’s Argument: Mature Chips Matter More

At roughly the same time, Richard Chang, founder of SMIC, publicly cautioned China’s semiconductor sector against obsessing over the global race for 2nm or 3nm process nodes.

Chang instead emphasized that mature-node and niche semiconductor markets are strategically more important, especially for supply‑chain security.

One reason is simple economics and demand: most semiconductor demand globally lies outside the leading edge, including chips used in automobiles, industrial systems, communications hardware, sensors, and power management.

These segments rely heavily on mature manufacturing processes rather than cutting‑edge nodes, making them a realistic and high‑impact area for China to strengthen domestic capacity.

Export Controls Accelerated the Shift

Another driver of this strategy is geopolitics.

U.S. and allied export controls introduced since 2022 have restricted China’s access to advanced chips and the equipment required to produce them, especially for AI and high‑performance computing. According to analysis from the Center for Strategic and International Studies (CSIS), the controls have disrupted Chinese access to leading‑edge technologies while simultaneously accelerating Beijing’s push for indigenous semiconductor capabilities.

Rather than abandoning advanced-node research entirely, China appears to be pursuing a layered approach:

• Continue long‑term efforts toward advanced-node manufacturing
• Rapidly expand domestic capacity in mature nodes
• Build local design ecosystems around domestic processors

The Loongson 3A6000 milestone fits neatly into this approach.

Reducing Dependence on Intel, AMD, and Nvidia

China’s reliance on foreign chips has historically been greatest in three areas: desktop CPUs, server processors, and AI accelerators dominated by companies such as Intel, AMD, and Nvidia.

Deploying domestic CPUs in government and institutional computing helps chip away at that dependency. Even modest performance parity with older Western chips can be sufficient for many workloads such as office computing, government systems, and enterprise applications.

For AI and data center workloads, domestic processors alone are not a full substitute for high‑end Nvidia GPUs. However, local CPUs, accelerators, and system‑level innovations can still enable regional AI deployments where cutting‑edge performance is not essential, especially in government and industrial settings.

In this sense, substitution is gradual rather than immediate.

Building the Semiconductor Stack From the Ground Up

The broader goal behind these efforts is not simply to produce a single competitive chip. It is to assemble a complete domestic semiconductor stack, including:

• Chip design and architecture
• Manufacturing at viable nodes
• Software ecosystems
• Supply chains for materials and components

For example, China is also pushing to localize upstream supply chains such as silicon wafers, targeting more than 70% domestic sourcing for wafer inputs used by Chinese chipmakers.

Taken together, these initiatives aim to reduce the systemic risk created by dependence on foreign suppliers.

“Resilience Before Frontier Leadership”

Viewed together, Loongson’s shipment milestone and Chang’s mature‑node argument highlight a strategic shift.

Instead of defining success solely by breakthroughs at the smallest transistor sizes, China appears focused on building large‑scale domestic capacity across the semiconductor value chain—especially where the majority of real‑world demand exists.

That approach prioritizes resilience: ensuring China can supply the chips needed for government systems, industrial infrastructure, vehicles, and everyday computing even under geopolitical constraints.

Advanced-node leadership may remain a long‑term objective. But for now, the immediate goal is simpler and more pragmatic: make sure the country can build—and deploy—its own chips at scale.
