    寒武纪陈云杰称AI设计芯片已达十余年前手机处理器水平,AI正重塑半导体全链条

    寒武纪联合创始人陈云杰在2026世界顶尖科学家论坛表示,AI设计的启明-1(2021年)性能接近Intel 486,启明-2(2025年)达到十余年前主流手机CPU水平;其团队从100多个AI算法中提炼公共运算并设计AI指令集架构,华为采用该处理器架构用于第一代AI芯片,支付约2亿元授权费。诺奖得主Novoselov指出AI可预测二维材料改性结果但提醒真实材料更复杂。

    Ben Bajarin 转发一条描述 GPU 获取过程的内容并称这更接近他们实际听到的情况。转发内容列举了远期供给交易的典型流程:所谓有 GPU 的卖家往往只有 OEM 大概 Q1 '27 的排产线索,或尚未找到 colo 机房、未订购网络,常见报价如 $4.9/小时加 10% 预付款赌 RFS Jan '27,结果未上线只退回 50% 预付款。对比之下,立即可 RFS 的节点流程是买家先要 1 小时测试节点验证 InfiniBand 和存储网络,卖家报 $10/小时并要求 2 小时内 100% 预付,创业公司明知能以 $20/小时变现所以当场签约电汇。结论是远期 speculative 供给与即时 RFS 节点是完全不同的市场,低于 $7/小时的报价多半不真实。

    this is how finding GPUs goes: 1. someone says they have GPUs 2. you ask & turns out they have a lead on an OEM that will ship in maybe Q1 ‘27. 3. you ask & turns out they haven’t found colo space, haven’t ordered networking. 4. you ask & the OEM is SMC with optics in the hot aisle. back of your mind you also know SMC always rugs & ships late. 4. you ask & turns out they’re racked with hydra and they don’t even have final seller’s rights. 5. you say you’ll do $4.9/hr 10% prepay for RFS Jan ‘27. effectively betting there’s a 60% chance it goes live and you get ‘em 6. jan comes, not live, you get 50% of your prepay back and is what it is. everyone’s pissed. other scenario: 1. guy says he has GPUs RFS tmrw 2. you ask and get test node for 1hr, it has infiniband & storage nodes on network 3. he says $10/hr, sign in next two hrs 100% prepay or piss off. 3. startup knows they’ll make $20/hr so they grit their teeth & snap call sign plus wire. BMC without of band access is given same day, everyone’s happy! speculative market for yotta compute available maybe Q1 maybe Q3 ‘27 in yucatan is completely different than nodes with immediate RFS. anything under $7/hr probably isn’t real.

    Ben Bajarin转发@pequityresearch的Nebius研究要点,并称自己几周前所说的算力价格如今基本成了竞价。要点包括:Nebius采用竞价驱动的集群接入定价,通过竞争性抬价使价格水平提高约20%;要求60–65%预付款,相比高杠杆的CoreWeave(新债务利率高达15%)风险更低;短期现货容量每兆瓦ACV达4000万–5000万美元,竞价加持下或达6000万美元,中期合约则为2000万–2500万美元;最新一代GPU供应紧张将持续到2028年中,公司计划把2027年产能留给高毛利现货负载。研究还称Meta和SpaceX各自控制超过100万张GPU,每月部署2.5万–5万张,正从neocloud手中抽走裸金属合约;Gartner预测到2030年超过80%的独立neocloud将倒闭;Nebius核心客户Microsoft、Meta为AA/AAA评级而受保护;GB200/GB300正转向毛利高出4–8倍的推理负载;Micron预计HBM3/HBM4短缺将延续到2028年以后,Microsoft内部30万颗Maia ASIC替代了30万张以上Nvidia GPU的需求。

    Expert Takeaways: Nebius > Nebius operates an auction-driven cluster-access pricing model that drives up pricing levels by ~20% through competitive bidding. > Nebius requires 60–65% upfront contract payments, providing strong protection compared to debt-heavy peers like CoreWeave (facing up to 15% interest on new debt). > Short-term spot capacity fetches $40–50M ACV per megawatt (potentially up to $60M with auction uplift) vs. $20–25M for medium-term deals. > Tight supply for latest-generation GPUs through at least mid-2028 supports reserving 2027 capacity for high-margin spot workloads. > Meta and SpaceX control >1M GPUs and plan to deploy 25k–50k units monthly, pulling bare-metal contracts away from neoclouds. > Open-source models deliver comparable results at 70–80% lower cost, eroding OpenAI and Anthropic enterprise revenue. > Gartner projects >80% of independent neoclouds will fail by 2030 due to a K-shaped market favoring GB300/Vera-class hardware over older GPUs. > Nebius is insulated from cascading neocloud defaults because its core clients (Microsoft, Meta) are AA/AAA-rated, unlike BB-rated frontier labs. > High-end hardware (GB200/GB300) is shifting to inference workloads, which offer 4–8× higher margins than training. > Micron predicts HBM3/HBM4 memory shortages beyond 2028, while Microsoft’s 300,000 internal Maia ASICs displace demand for 300,000+ Nvidia GPUs. $NBIS $GOOGL $META $MSFT $AMZN

    Daishin Securities 报告称 CSP 和 AI 实验室曾请求开发 4-high、6-high 低堆叠 HBM 用于低端推理产品,这些计划现已搁置,8-high 重新成为最低堆叠高度;NVIDIA 因 base die 供应受限和客户优先带宽,Rubin 从 8-high 与 12-high 混合改为放弃 8-high,2027 年的 Rubin Ultra 多个架构变体正在流片,初期版本预计使用最高规格的 8-high HBM4,后续版本采用 8-high 或 12-high HBM4E;AMD 2027 年产品预计混合使用 8-high 与 12-high HBM4,即将推出的 MI450 预计将 CoWoS 封装内 HBM 堆叠数增至 12 个、提供 288GB HBM4;OpenAI 预计采用 12-high HBM4,Anthropic 预计采用 8-high HBM4。作者 Ben Bajarin 评论称,8-high 和 12-high 对训练 SKU 合理且将持续,但在整体组合中占比会更小,4-6 层更适合推理 SKU。

    Daishin Securities CSPs and AI labs: CSPs and AI labs had requested the development of lower-stack HBM products, such as 4-high and 6-high configurations, for use in low-end inference products. Those plans now appear to have been shelved, with 8-high once again emerging as the minimum stack height. NVIDIA: Rubin’s specifications have changed amid base die supply constraints and requests from customers prioritizing bandwidth over cost efficiency. The original plan called for a mix of 8-high and 12-high HBM, but the 8-high option appears to have been dropped. For Rubin Ultra, scheduled for release in 2027, multiple architectural variants are currently undergoing tape-out. Initial versions are expected to use the highest-specification 8-high HBM4, while subsequent versions are expected to adopt either 8-high or 12-high HBM4E. AMD: AMD is expected to use a mix of 8-high and 12-high HBM4 in its 2027 products. One notable development is the upcoming MI450, which is expected to increase the number of HBM stacks within the CoWoS package to 12, delivering 288GB of HBM4. The increase from eight to 12 HBM stacks per CoWoS package is a positive development for HBM content over the medium to long term. OpenAI and Anthropic: OpenAI is expected to adopt 12-high HBM4, while Anthropic is expected to use 8-high HBM4.

    I spent two days touring Intel’s most advanced fab and talking to its technical leadership to understand what the chips of the future will look like. A lot of what's coming next – gate-all-around transistors, backside power, CFET, hybrid bonding – is hard to follow without actually seeing it, so we made all the awesome animated explainers that I wish I had while I was prepping. I also asked Intel’s leadership how the semiconductor industry will cope with the enormous shock in demand from AI. AI compute has grown 3x a year for the last decade, but according to Intel's CTO, Intel could only double leading-edge wafer production with today’s global stock of chipmaking tools.
