Xinxin Hangtu launches X7 Ultra ADAS chip with 700 TOPS
KEY FACTS
- Xinxin Hangtu has launched the X7 Ultra, an ADAS chip for large models, with 700 TOPS of large-model compute.
- The chip uses a super-core NPU architecture, with intra-core interconnect speeds TB/s higher than inter-core links.
- The chip has hardware optimizations for key Transformer operators and natively supports FP16/FP32 vector compute.
- The X7 Ultra is the first in China to mass-produce an Armv9 automotive-grade CPU, integrating the SVE2 vector engine.
- CEO Li Zonglin said the chip's architecture was designed backward from production-model requirements, a direction set when the company was founded in 2023.
KEY DATA
700 TOPSLarge-model compute
99.99%Measured alignment with production models
98.7%Compute utilization
80%Memory bandwidth consumption reduction
PHYSIX OBSERVATION
As end-to-end large models move onto vehicles, chip competition is shifting from stacking raw compute to competing on effective compute, and the X7 Ultra is using operator-level optimization and energy-efficiency data to seize the narrative. But the 99.99% alignment figure is the vendor's own testing, and real production performance remains to be verified; being first to mass-produce an Armv9 automotive-grade CPU is a differentiating chip, but ecosystem adaptation is still a hard battle.
