According to a research report released by CITIC Securities, PCIe, a pivotal protocol for interconnecting CPUs with peripheral devices, often sees its burgeoning market demand go unnoticed. In the era of AI, the native PCIe lanes provided by CPUs are limited, while GPUs demand a high number of lanes. Consequently, PCIe Switches become essential for lane expansion. The report forecasts that by 2028, the global market size for PCIe Switches is projected to soar to 30 billion yuan, with the domestic computing power chip-matching (supporting) market space accounting for roughly 7 billion yuan, marking a more than twofold increase from 2026. Presently, domestic substitution is still in its nascent stages. It is thus advisable to keep a close watch on companies that are relatively advanced in this domain, as well as those anticipated to make an entry into the PCIe Switch market.
