超节点专题解读 20260329 摘要 阿里、腾讯、字节自研超节点方案（128/64/272 卡）预计 2026 年 Q3 末（8-9 月）进入大规模量产起量阶段。 2026 年超节点招标需求明确：腾讯约 2,400 台，阿里与字节各约 2000 台；招标集中在 3-4 月、6-7 月及 9-10 月。 超节点方案盈利能力显著优于传统 8 卡机：净利率由 1%升至 3%，毛 利率由 4%升至 8%，主因供应商可控成本空间翻倍。 生产端良率是核心瓶颈：目前现网良率不足 35%，需在 2-3 个月内提升 至 75%量产阈值，英维克液冷方案具备领先优势。 供应链格局：浪潮、华勤、新华三、超聚变、中兴为核心供应商；申科 通信、重芯微在 Switch 芯片国产替代中进展较快。 2026 年资本开支高企：字节预计 3,000 亿，阿里 2,500 亿（含海外上 修），腾讯 1,500 亿；下半年或策略性转向采购国产 CPU（如海光）。 国产推理芯片需求爆发：2026 年腾讯、字节、阿里合计需求约 210 万 颗，预计实际交付率约为计划的 80%。 Q&A 请介绍一下当前主要互联网厂商在超节点方案上的整体进展，包括各家的具 ...
