NPU不够，诚恒微为什么还给端侧AI芯片加了GPGPU？

TL;DR - Chengheng Micro launched the CH3715 edge-AI SoC, combining a 48-TOPS NPU with a CUDA-compatible GPGPU and other accelerators. Its heterogeneous design aims to replace multi-chip systems in machine vision, radar, industrial equipment, and robotics.

• The NPU handles neural inference, while the 1-TFLOPS FP32 GPGPU supports programmable, high-precision parallel workloads unsuitable for INT8 inference.
• The SoC also integrates CPU, DSP, FFT, GPU, VPU, dual ISP, PCIe 4.0, and 10Gb Ethernet to reduce data movement, latency, power, and integration complexity.
• Chengheng Micro claims single-chip integration can raise data throughput by over 50%, cut power by 30%, and shrink system size by 40%, though broader real-world validation is still needed.
• Its next generation will prioritize memory bandwidth and embodied-AI workloads while reducing die area and targeting roughly half the first-generation cost.
