Introducing the Sophgo SG2380: A Powerful SiFive P670 RISC-V Processor with AI Acceleration

Sophgo SG2380 is an upcoming 2.5 GHz 16-core RISC-V processor based on SiFive Performance P670 cores and equipped with a 20 TOPS AI accelerator using SiFive Intelligence X280 and Sophgo TPU. It will be featured in a $120 desktop-class mini-ITX motherboard in the second half of 2024. The RISC-V processor supports up to 64GB RAM, UFS 3.2 and SATA 3.0 storage, an Imagination GPU for 3D graphics, and a VPU capable of 4Kp60 video decoding. The system can manage locally deployed larger-scale LLMs like LLaMA-65B without the need for external NVIDIA or AMD accelerator cards.
