notes
PRIMARY VENDOR SOURCE. 4U, 8 NPUs, max 350 W per NPU module, PCIe 4.0 x16 per NPU with 'total bidirectional interconnection bandwidth between four CPUs and eight NPUs is 512 GB/s'. Network is 'Connected directly through 200GE QSFP ports, RoCE protocol'. Ships in 32 GB HCCS / 32 GB PCIe / 64 GB HCCS NPU variants, PCI ID 0x19E5:0xD802. Notably Huawei publishes the host-side interconnect budget but no chip-to-chip HCCS figure for this generation. | SOURCE AUDIT 2026-10-03: a plain HTTP probe from an unauthenticated datacenter IP gets HTTP 403 'Access Denied' from support.huawei.com. That is anti-bot gating, NOT evidence the document moved or is dead, so the URL is deliberately left unchanged and no archived_url was substituted. A future auditor should re-verify from a browser session rather than recording this as a dead link.
