A股复盘 | 缅癌 / 2025.04.23 肿么回事，兄弟姐妹萌，当我早上看到贝森特、懂王的一系列操作，我心想今天 稳了！！冲锋！ 结果，我的A股啊！怎么就高开低走了？沪指最后怎么绿了？ 从媒体报道时间来看，先是贝森特在一场私人会议上表态，说中美局势会缓和。 贝森特说，美国对中国商品征收145%的关税，中国对美国商品征收125%的关 税，这种现状是不可持续的，并称"不久的将来"将出现降级，将让市场"松一口 气"。 紧接着，白宫新闻秘书表示，特朗普正在为与中国达成贸易协议奠定基础，与中 国的关系正在朝着正确的方向推进。 随后特朗普亲自对记者说， 他在与北京的谈判中会"非常友好"，并表示一旦达成 协议，美国对中国进口商品征收的关税将大幅下降，但不会降为零。 啧啧啧，感觉跟之前彭博的报道相一致，中方要看到尊重人的态度才能进行下一 步 懂王只能收起那副嘴脸，来了这么一计！ 受此消息影响，今天出海产业链、消费电子链都回暖了！要说涨得最好的还是机 器人！ 大约有两个消息吧，一个是马斯克，虽然一季度业绩数据糟糕，但是马斯克还是 继续画饼，到今年年底，将有数千台Optimus机器人在特斯拉工厂工作；有信心 预测到2029年 ...

如果您希望可以时常见面，欢迎标星收藏哦~ 在AI的狂飙猛进中，大模型规模呈指数级增长态势，从最初的 GPT-3的1750 亿参数，到如今前 沿模型迈向万亿级参数的征程，每一次跨越都对计算资源提出了近乎苛刻的要求，尤其是存储带 宽，给传统的内存技术带来了巨大挑战。 在过去几十年中，服务器硬件的算力峰值基本以每两年3倍的速度飞速增长，展现出强大的计算潜 力。然而，DRAM带宽的增长速度却仅为每两年1.6倍，片间互连带宽的增速更是只有每两年1.4 倍。这种不均衡的发展速度，使得在长达20年的时间跨度里，造成了内存的存取速度严重滞后于 处理器的计算速度，内存瓶颈导致高性能处理器难以发挥出应有的功效，这对日益增长的高性能计 算形成了极大的制约。 这种不均衡的发展，被业界称为"存储墙"问题。 "存储墙"的存在使得处理器的性能无法得到充分发挥，严重制约了AI模型的训练和推理速度。有 相关研究表明，在一些大规模的AI训练任务中，由于内存墙的存在，处理器的实际利用率可能只有 理论峰值的20% - 30%，这无疑是对计算资源的巨大浪费。 直到HBM的出现，宛如一场存储领域的革命，彻底改变了传统DRAM的布局模式。HBM 凭借其 ...
