Alibaba T-Head Zhenwu 810E
Alibaba's in-house AI accelerator (the T-Head PPU): 96 GB of HBM2e at 2.77 TB/s, 700 GB/s chip-to-chip links and 400 W, running in 10,000-card clusters on Alibaba Cloud for more than 400 customers. Sources and verification dates.
Every published figure
Source per value- Owner The company that specified the chip and runs it in its own cloud, data centers or products.
- Alibaba 1
- Role What the owner says the chip is for: training, inference, both, or a general-purpose server CPU.
- Training and inference 2
- Design partner The ASIC house that co-designed or physically implemented the chip (Broadcom, Marvell, MediaTek, Alchip, GUC and others), as stated by the owner, the partner, a filing or named trade-press reporting. 'In-house' when the owner states it designed the chip itself, including through an acquired team such as Annapurna Labs.
- In-house (T-Head) 2
- Memory On-package memory type (HBM2e, HBM3, HBM3E, LPDDR5) or, for CPUs, the memory the socket drives (DDR5).
- HBM2e 1
- Memory capacity GB On-package memory per chip in GB. Blank for CPUs, whose memory sits off-package.
- 96 1
- Memory bandwidth TB/s Peak memory bandwidth per chip in TB/s, as published.
- 2.77 1
- Precision note What the throughput figures mean: dense or sparse, which precision, per chip or per package, and any figure the owner states only in another unit.
- No FLOPS figure published; T-Head positions it against NVIDIA's H20. 2
- Power W Chip or package power in watts as published (TDP, TBP or typical power; the source says which).
- 400 1
- Status Announced: public roadmap without verified deployment. Sampling: first silicon or limited internal use. Preview: customers can request early access, without a GA claim. Deployed: stated production use or general availability. Discontinued: program stopped.
- Deployed 2
- Announced Year the owner first announced the chip publicly.
- 2,026 2
- Deployment scale The largest deployment the owner or a named report states: chip counts, clusters, gigawatts or regions.
- Deployed in 10,000-card clusters on Alibaba Cloud (January 2026); Zhenwu shipments reached 560,000 units by May 2026. 2
- How to get it How an outside buyer can use the chip: a named cloud instance or service, a product, or 'Internal only'.
