XHEART New Silicon Voyage Releases X7 Ultra Large-Model Chip
2 reports · 2 sources
XHEART New Silicon Voyage released the automotive-grade SoC X7 Ultra on October 29, focused on bringing large models onto vehicles, with large-model compute reaching 700 TOPS. The company claims its memory bandwidth consumption is 80% lower than industry flagship products and energy efficiency is improved by 100%, and that measured NPU compute utilization can reach 98.7%; these performance figures are based on real production intelligent-driving large-model evaluations and premised on the quantized model output achieving over 99.99% similarity with the post-training FP32 floating-point model. The chip follows a "large models define the chip" approach, deriving the architecture backward from model inference requirements, meets ASIL-B functional safety requirements, and has a built-in safety MCU certified to ASIL-D. The company also announced X9 R&D targets: 3000 TOPS large-model compute and 700GB/s single-chip memory bandwidth, planned for launch in 2027. As of October, the first-generation X7 series has been deployed on more than 10 vehicle models, with cumulative shipments exceeding 200,000 units, and another 40 vehicle models are nominated and awaiting delivery.
