Xiaomi (小米) says new-generation SU7 will pack third-gen Snapdragon 8 and a 4nm, 700‑TOPS driving chip

Big compute, new electrical architecture

Xiaomi (小米) used its spring product event to unveil a major electronics and electrical architecture upgrade for the next-generation SU7 sedan, the company’s flagship electric model. Founder and CEO Lei Jun said the car’s domain controller has been reworked as a four‑in‑one module for higher integration and greater on‑board compute. The headline: the SU7 will use the third‑generation Snapdragon 8 mobile platform alongside a dedicated driver‑assistance compute chip.

Connectivity and on‑car features

Xiaomi said the new SU7 supports advanced communications including dual‑5G dual‑SIM active connectivity, UWB near‑field vehicle control, Wi‑Fi 7 in‑car networking, and multiple IoT interfaces, as well as a built‑in ETC toll module that Xiaomi says will be activated free of charge. It has been reported that the auxiliary driving compute chip is manufactured on a 4nm process and delivers roughly 700 TOPS of inference performance, and that the SU7’s core electronics board has passed automotive‑grade testing.

Why it matters beyond China

For Western readers: SU7 is Xiaomi’s push to compete in the crowded Chinese EV market by leaning on its consumer‑electronics strengths — powerful mobile silicon and tight device integration — rather than purely automotive incumbency. Using Qualcomm’s high‑end Snapdragon line underscores the continued role of cross‑border chip supply in Chinese vehicles, even as Washington and other governments weigh export controls and trade policy aimed at advanced semiconductor technologies. Is Xiaomi buying off‑the‑shelf horsepower, or preparing to design more of it in‑house? Either way, the emphasis on large TOPS counts and new connectivity standards signals how quickly cars in China are becoming data centers on wheels.
