DigiTimes综述澜起Q3净利翻倍及得一微CXL布局，核心业绩预告已于10月20日官方披露

China's IC designers are expanding into high-speed interconnect technologies as AI inference and agent applications fuel demand for server CPUs, memory modules and connectivity chips. Montage Technology expects third-quarter 2026 profit to more than double on stronger DDR5 shipments, while Shenzhen-based Techwinsemi is developing Compute Express Link (CXL) memory expansion controllers. Together, these efforts highlight China's growing interest in AI server connectivity.

DDR5 upgrades lift Montage's profit and margins
In a preliminary earnings announcement on October 20, Montage forecast third-quarter revenue of CNY2.079 billion (≈ US$311.3 million), up 46% year-on-year and 10.9% sequentially. Net profit attributable to shareholders is expected to reach CNY1.2 billion to CNY1.3 billion, up 153.6% to 174.7% year-on-year and 4.3% to 13% quarter-on-quarter.
Excluding non-recurring items, profit is projected at CNY950 million to CNY1.05 billion, up 152.6% to 179.2% year-on-year and 32.2% to 46.1% sequentially. In the year-earlier quarter, Montage recorded revenue of CNY1.424 billion, net profit of CNY473 million and adjusted profit of CNY376 million, with basic earnings per share of CNY0.42.
Montage attributed the growth to expanding AI inference and agent workloads, which are lifting server CPU demand and, in turn, shipments of DDR5 memory interface and supporting module chips. Third-, fourth-, and fifth-generation registering clock driver (RCD) chips accounted for a larger share of shipments, improving the company's product mix.
RCD chips buffer and drive clock signals in server memory modules, preserving signal integrity at higher capacities and transfer speeds. Growing adoption of newer-generation DDR5 interfaces is therefore supporting both shipment growth and profitability.
Montage expects interconnect chip revenue of CNY2.047 billion, up 49.3% year-on-year and 20.9% sequentially, accounting for nearly 98.5% of total revenue. Gross margin is projected at 68% to 68.5%, a year-on-year improvement of 2.31pp to 2.81pp. The company anticipates further demand growth in the fourth quarter.
The estimates remain unaudited, with final figures subject to Montage's third-quarter financial report.
Techwinsemi pushes into CXL memory expansion
Beyond DDR5, Techwinsemi is developing its H9560 controller for CXL memory expansion, targeting completion of wafer-return validation by the end of 2026. Its efforts also cover enterprise storage controllers, firmware, solution validation and system compatibility, alongside supply-chain integration and customer adoption.
Built on the PCI Express physical interface, CXL enables high-speed connectivity and resource sharing among CPUs, accelerators and memory devices. Through memory expansion, pooling and sharing, the technology can help data centres allocate capacity more flexibly and improve utilisation for demanding AI workloads.
While Montage focuses on DDR5 memory interfaces and interconnect chips, Techwinsemi is pursuing storage controllers and CXL expansion solutions. Their respective strategies reflect the growing importance of memory capacity, bandwidth and system integration as AI workloads increasingly shift towards inference and autonomous agents.
For Chinese IC designers, high-speed interconnects are becoming an increasingly important part of AI infrastructure, linking advances in memory performance with the need for tighter coordination among server CPUs, accelerators and storage systems.
