NVIDIA Corporation (NASDAQ:NVDA) is one of the 10 AI Stocks Gaining Attention on Wall Street. On February 2, Bank of America reiterated the stock as “Buy” with a $275 price target. The firm said that investors should buy any weakness in shares. “Our $275 PO is based on 28x CY27E PE ex cash, within NVDA’s historical 25x-56x forward year PE range, which we believe is justified by NVDA’s leading share in fast-growing AI compute/networking markets, offset by lumpiness in global AI projects, cyclical gaming ma ...

智通财经APP获悉，广发证券发布研报称，AI的Memory时刻，AI记忆成为支撑上下文连续性、个性化 与历史信息复用的底层能力，持续扩展模型能力边界，有望促进AI Agent等应用加速落地。AI记忆的价 值正从"费用项"转变为"资产项"，相关上游基础设施价值量、重要性将不断提升。建议关注产业链核心 受益标的。 广发证券主要观点如下： 英伟达推出AI推理上下文存储平台ICMS 随用户多轮会话与Agent持续运行带来的KVCache不断累积，系统对可长期留存并按需回填的分层 KVCache形成刚性需求，推动上下文从HBM外溢至DRAM、SSD等分层介质承接。为此，NVIDIA推出 上下文记忆存储架构ICMS，面向Agent与多轮推理场景提供"长期上下文记忆层"，一方面承载更大规模 KVCache，另一方面以低延迟将历史KVCache回填到多GPU节点的多回合推理会话;其KV访问模式呈现 低TTFT约束下的高并发、高吞吐随机读取。 ICMS平台对SSD使用效果好 经济性与扩展性方面，SSD单位成本显著低于GPU内存，且可按TB、PB容量扩展，是长期上下文的天 然承载介质。可行性方面，根据《Context Memor ...

【文/观察者网 阮佳琪】 前脚刚有消息称英伟达CEO黄仁勋对OpenAI心存不满、千亿投资谈判迟迟没有进展，后脚OpenAI又被 曝出"看不上"英伟达的人工智能（AI）芯片，这一系列动向让AI热潮中最受瞩目的这两家美国企业之间 的关系愈发复杂。 当地时间2日，路透社援引多位知情人士消息称，OpenAI对英伟达最新推出的部分AI芯片在推理环节的 表现感到不满（即模型响应用户查询和请求的过程），自去年起已着手寻找替代方案。 据七名消息人士透露，OpenAI的核心不满集中在速度层面：英伟达硬件在处理软件开发、AI系统间通 信等特定问题时，向ChatGPT用户输出答案的响应速度未达预期。 报道称，OpenAI的战略转向，愈发重视用于执行AI推理特定环节的芯片，而传统英伟达GPU依赖外部 存储的架构，与推理任务需频繁读取数据的需求存在矛盾，反观Anthropic、谷歌等竞争对手，早已依 托谷歌自研的张量处理单元（TPU）占据优势。这类专为推理计算设计的芯片，性能表现优于英伟达的 通用GPU。 一名消息人士补充，这一问题在OpenAI大力推广的代码生成产品Codex上体现得尤为突出，公司内部员 工也将Codex的部分性能 ...
