[News] China’s Xiaomi and Unisoc Claim Domestic 4nm Mobile Processors Coming Soon
As China keeps reducing its reliance on the global semiconductor supply chain with strong support from the authority, two major smartphone manufacturers reportedly claim to have already taped out their own 4nm mobile processors. According to the reports by Liberty Times and Commercial Times, Xiaomi and Unisoc, by using foreign IP cores from ARM and IMG, have successfully taped out domestic 4nm chips.
According to the latest data from TrendForce, Xiaomi (including Xiaomi, Redmi, and Poco) has moved past last year’s high inventory issues, achieving a total production of 41.1 million units in the first quarter and ranking third globally in market share, only after Samsung and Apple. Oppo, Transsion and Vivo are the other three Chinese smartphone brands having made it to the top six regarding global shipments.
Shanghai-based fabless chip firm Unisoc, on the other hand, is specialized in areas including 2G/3G/4G/5G, Wi-Fi, Bluetooth, TV FM, satellite communications and other related technologies, according to its website.
Citing comments from Chinese tech blogger “Oneline Technology,” the reports point out that Xiaomi’s self-developed chip has made a significant leap forward, while the performance of its 4nm chip is similar to that of Huawei’s Kirin 9000s, and is expected to be seen this year. Huawei’s Kirin 9000s is reportedly manufactured by SMIC’s 7nm.
Citing another Chinese blogger, “Fixed Focus Digital,” the reports mention that Unisoc’s 4nm chip has already taped out, achieving performance levels comparable to Qualcomm’s Snapdragon 888.
Regarding the timeline for Chinese domestically produced smartphone SoCs to reach 4nm, the reports, citing industry insiders, state that it is more likely to happen in 2026. For now, MediaTek and Qualcomm still dominate Chinese’s smartphone chip market.
