英伟达已为其Rubin Ultra系统减少了高带宽内存（HBM）配置，从HBM4E 12-Hi（384GB）降级到HBM4 8-Hi（192GB）。这一决定源于近期HBM和DRAM的价格上涨，导致内存约占总资本成本的40%。通过“削减规格”，英伟达旨在削减超过50%的成本，并将资本重新分配给网络基础设施，例如用于机架间互连的扩展网络。 AI
影响 英伟达的这项成本节约措施可能表明更广泛的供应链压力正在影响AI硬件的开发和部署。

The takeaway: despec is a symptom of the supply crunch, not weakening demand. When the industry's largest, best-positioned buyer is stripping memory content just to manage cost and availability, pricing power sits firmly with suppliers — and the shortage is broadening, not
The despec cuts HBM cost by >50% — even with the 2026 HBM price hike already baked in — and takes memory from ~40% to ~28% of total capital cost. But that spend doesn't vanish. It's redirected into scale-up networking: on the NVL576 NPO SKU, scale-up triples from 4% to 12% of…
Nvidia has despecced Rubin Ultra's HBM: from HBM4E 12-Hi (384GB) down to HBM4 8-Hi (192GB). Why strip memory out of your flagship rack-scale system? Because after the latest HBM and DRAM price hikes, memory had quietly become ~40% of total capital cost of ownership. We ran the …
