Xinxin Hangtu unveils X7 Ultra auto chip with 700 TOPS NPU

KEY FACTS

  • Xinxin Hangtu made its first public appearance and launched the X7 Ultra automotive-grade chip.
  • The X7 Ultra's NPU delivers 700 TOPS with a compute utilization rate of 98.7%.
  • The chip's quantized model output shows over 99.99% similarity to the FP32 baseline.
  • The X7 Ultra uses an Arm v9 automotive-grade CPU, the first deployment of this architecture in China.
  • The chip's SoC meets ASIL-B and its integrated MCU meets ASIL-D functional safety standards.

PHYSIX OBSERVATION

Xinxin Hangtu defined its chip metrics using Momenta's production models, pulling the compute narrative from theoretical TOPS back to real deployment efficiency. For the industry, hardware-software co-design is becoming the new threshold for smart-driving chip competition; but 700 TOPS is not top-tier, and whether it can deliver a tenfold experience improvement every year still depends on actual performance in production vehicles.
