Nvidia Sells Cards, Montage Sells "Water": The Hotter AI Gets, the More This Chinese Chip Company Earns

Montage Technology announced on its official WeChat account: the fifth-generation DDR5 Registering Clock Driver chip (RCD05) has officially entered mass production. This chip supports data transfer rates of 8000 MT/s, roughly 11% faster than the previous generation, and is mounted on high-performance server memory modules, specifically providing bandwidth for AI servers and data centers.

The name sounds convoluted, but you can think of it as the "commander of memory sticks": when dozens of memory modules in a server are all talking to the CPU at the same time, who speaks first and at what tempo is entirely coordinated by this chip. The faster the memory sticks, the harder it is for the commander to keep up, so every generation has to be redesigned.

Q1 Profit Hit 847 Million Yuan, Up 61% Year-over-Year

Let's start with Montage Technology's Q1 report card this year: revenue of 1.461 billion yuan, up 19.5% year-over-year; net profit of 847 million yuan, up 61.3% year-over-year. The interconnect chips driving these profits achieved a gross margin of 71.5%, 7 percentage points higher than the same period last year.

What does 71.5% mean? Most chip design companies on the A-share market have gross margins between 30% and 50%, and those that can consistently stay above 70% are few and far between. The general rule in the chip industry is: the closer a business is to algorithms, the easier it is to run. For a company making "tiny chips next to memory sticks" to hit this number, it relies on a different logic — globally, the manufacturers that can supply DDR5 Registering Clock Drivers can be counted on two hands, and Montage is one of them, and the one with the largest market share.

The Hotter AI Gets, the More Memory Sticks Are Needed, the More It Earns

The transmission chain of this equation is straightforward: as AI inference and Agent applications run more and more, workloads migrate from the training side to the inference side, and the demands on real-time CPU scheduling grow ever higher. Montage Technology's assessment at its earnings briefing is that the CPU allocation ratio in AI servers will continue to rise, and increased CPU demand will directly drive up memory module usage, which in turn amplifies the market size for memory interconnect chips.

In plain terms: every additional GPU Nvidia sells, the server needs to be equipped with another batch of memory sticks, and every memory stick needs a Montage chip on it. GPUs are the ticket to compute power; Montage collects the toll. The hotter the tickets sell, the steadier the toll revenue.

This explains why an unremarkable little chip can have a gross margin that beats most companies making "big chips."

Competition Is Catching Up, but the Rhythm Is Still in Its Hands

When business is good, more rivals start watching. America's Rambus launched a server memory chipset supporting 9600 MT/s in July this year, already surpassing Montage's just-mass-produced fifth generation in specs. However, Montage's sixth-generation chip (9200 MT/s) already had samples sent out in June this year, so its R&D pace hasn't fallen behind.

The real moat lies elsewhere: memory interface chips require years of validation with CPUs and memory manufacturers before entering the supply chain, and customer switching costs are extremely high. Rambus can grab some share, but in the short term it can't shake Montage's foundation. Additionally, Montage is the first to trial-produce on the new CXL memory expansion controller track, and Samsung's and SK Hynix's next-generation products have already adopted its chips, so the second growth curve is already unfolding.

The Industry Signal Behind One Chip

Looking back at this news, the most interesting part is that it draws a more complete map of the AI industry chain. Everyone is fighting tooth and nail over GPUs, but in reality, every step up the AI server ladder — from graphics cards to memory, from memory sticks to the management chips on them — has companies quietly counting their money.

The memory price surge continues, and AI's appetite for memory shows no sign of slowing. Next time you see news that "memory prices are rising again," you can casually check Montage's stock price — it's most likely two sides of the same story.
