Despite investment, Chinese memory producers like CSMT are roughly 3-4 years behind Korean industry leaders. Their competitive impact is largely confined to China's domestic market (25% of global demand), where they supply low-to-mid-range products and aren't yet challenging leaders on the high-end global stage.

Analyst Chris Miller argues China's core challenge is manufacturing, as it lacks the advanced lithography tools monopolized by ASML. The US and Taiwan are projected to produce 30 times more quality-adjusted AI chips, a gap unlikely to close soon.
China's pause on Nvidia H200 chip orders is not a permanent ban but a strategic move. The government aims to balance its immediate need for advanced AI chips with its long-term goal of fostering a competitive homegrown chip industry, preventing over-reliance on Western technology.
With new factory capacity years away, the only immediate lever for increasing DRAM supply is "node migration." This involves shifting production to more advanced manufacturing processes (like 1B and 1C) that can produce more memory bits per silicon wafer. The speed of this migration is the critical factor for easing supply.
The most dangerous policy mistake would be reverting to a 'sliding scale' that allows China to buy chips that are a few generations behind the cutting edge. In the current era of AI, performance is aggregatable. China could simply purchase massive quantities of these slightly older chips to achieve compute power equivalent to frontier systems.
The real long-term threat to NVIDIA's dominance may not be a known competitor but a black swan: Huawei. Leveraging non-public lithography and massive state investment, Huawei could surprise the market within 2-3 years by producing high-volume, low-cost, specialized AI chips, fundamentally altering the competitive landscape.
Contrary to the narrative of a simple "tech race," the assessment is that China is already ahead in physical AI and supply chain capabilities. The expert warns that this gap is not only expected to last three to five years but may widen at an accelerating rate, posing a significant long-term competitive challenge for the U.S.
China can compensate for less energy-efficient domestic AI chips by utilizing its vast and rapidly expanding power grid. Since the primary trade-off for lower-end chips is energy efficiency, China's ability to absorb higher energy costs allows it to scale large model training despite semiconductor limitations.
America's competitive AI advantage over China is not uniform. While the lead in AI models is narrow (approx. 6 months), it widens significantly at lower levels of the tech stack—to about two years for chips and as much as five years for the critical semiconductor manufacturing equipment.
China's semiconductor strategy is not merely to reverse-engineer Western technology like ASML's. It's a well-funded "primacy race" to develop novel, AI-driven lithography systems. This approach aims to create superior, not just parallel, manufacturing capabilities to gain global economic leverage.
Despite record profits driven by AI demand for High-Bandwidth Memory, chip makers are maintaining a "conservative investment approach" and not rapidly expanding capacity. This strategic restraint keeps prices for critical components high, maximizing their profitability and effectively controlling the pace of the entire AI hardware industry.
