Hanguang 800 NPU (AI Inference Chip)
Unveiled at the Apsara Conference on 2019-09-25 by T-Head under Alibaba DAMO Academy. It uses a self-developed hardware framework with algorithms optimized for retail and logistics workloads in the Alibaba ecosystem. At launch it was already used internally for e-commerce product search, automatic translation, personalized recommendation, advertising and intelligent customer service. Alibaba stated it plans to empower clients by providing access through its cloud business (no standalone hardware sales). Official ResNet-50 inference results: single-chip peak 78,563 IPS; energy efficiency 500...
Key Highlights
- Self-developed hardware architecture optimized for cloud AI inference
- ResNet-50 peak 78,563 IPS and 500 IPS/W energy efficiency (official press release)
- powers internal e-commerce search/recommendation/ads/customer service
- compute delivered through Alibaba Cloud services
