显卡还没跑满,数据中心先被“网线”卡脖子了
3 6 Ke· 2025-12-17 01:23
不是,这年头用在电视上的 Micro LED 技术 ,还能做成网线,用来传数据了? 是这样的,前阵子托尼在网上刷到这样一条新闻,说微软正在研究通过 Micro LED 光互联技术(MOSAIC),来解决算力中心的数据传输,被 "卡脖子" 的问题。 而数据中心的端口交换速率,100 Gbps 早就已经是主流,AI 算力中心的交换机,更是要做到 400 Gbps 起步。 emmm,虽然听起来很抽象,但是负责数据处理的算力中心,反过来被数据传输卡了脖子,竟然是因为算力中心的网线 "不够用了"。。。 你可能好奇了,我这会儿上某东搜条超六类的万兆(10Gbps)网线也就十几块钱,咋能不够用呢? 但其实它们跟数据中心用的网线,在连接速率上,差了可不止一个数量级 —— 我们家里的网线,通常能承载的最大速率就是 1000 Mbps - 2500 Mbps,也就是 1 Gbps - 2.5 Gbps。这两年部分地区在推广 "万兆网络",匹配了 10 Gbps 的 网线,但这几乎就是民用网线速率的上限了。 其实就是因为 AI 大模型越来越大,在做训练和推理的时候,服务器之间和 GPU 之间,都得交换大量数据,对带宽的需求也就跟着 ...
真·自动驾驶要来了,但它可能没你想的那么好
3 6 Ke· 2025-12-17 01:23
我是万万没想到,传说中的自动驾驶就这么水灵灵地来了。 就在昨天,央视新闻在全平台发了一条看似平平无奇的消息,说是有两台新车已经获得了国内首批L3级别有条件自动驾驶的生产准入许可,将在北京、 重庆指定区域开展上路的试点。 至于为啥,简单来说就是这两台新车的准入,标志着 L3 级别的真·自动驾驶已经从原先的只能测试,变成了可以量产上车了。这给整个自动驾驶行业来了 针兴奋剂: 车企们终于不用在盯着辅助驾驶卷啦,都来做自动驾驶吧! 要知道,虽然看着都是 L3 的测试,但这回的两台新车意义可和之前完全不同。 简单说一下什么是 L3 级自动驾驶吧,里头的 L 其实就是 Level 等级的意思。按照自动驾驶的分级标准,自动驾驶总计可以被分为下面这样的 L0-5 的分 级。 对于已经习惯无人快递车满街跑的的兄弟们来说,这事儿乍一看好像都算不上新闻。 毕竟自动驾驶的萝卜快跑都已经开到 22 个城市了,不同车企拿到不同地方的 L3 测试牌照也时不时就会听见,自动驾驶测试啥的真就说不上新鲜。 可在这个新闻发出之后,不仅是自动驾驶有关的企业股价直线飙升,我们从业者粉丝群里的老哥们也是一条新闻从早发到晚,越发越起劲。 很明显这事儿不仅 ...

工业和信息化部许可两款车型产品,长安和极狐饮“头啖汤” 我国自动驾驶迈入L3级时代
Shen Zhen Shang Bao· 2025-12-16 23:35
深圳商报首席记者 陈小慧 自动驾驶L3正式落地。近日,工业和信息化部在官网发布消息称,许可两款L3级自动驾驶车型产品, 分别是长安牌SC7000AAARBEV型纯电动轿车和极狐牌BJ7001A61NBEV型纯电动轿车。这意味着,L3 级自动驾驶车可以正式"上路",自动驾驶技术从辅助驾驶向更高阶自动化迈进了关键一步。 许可设定严格限制 L3级,是自动驾驶的关键分水岭。根据《汽车驾驶自动化分级》(GB/T 40429-2021)国家标准,驾驶 自动化分成0级至5级共六个等级。其中0—2级属于辅助驾驶,具体来说,L0级属于应急辅助,L1级是 部分驾驶辅助,L2级是组合驾驶辅助;而L3级属于有条件自动驾驶,即系统在特定条件下完成全部驾 驶任务。与L2级不同的是,L3级自动驾驶在系统激活且未超出设计运行条件的情况下,驾驶主体从驾 驶员转移至自动驾驶系统。 12月15日,华为乾崑智能汽车解决方案在其官方社交平台发文确认了极狐阿尔法S(L3版)搭载了华为 乾崑智驾ADS。据统计,今年前三季度,华为乾崑智驾领航辅助NCA市场占有率达27.8%,在35万元以 上的豪华车型中,搭载率高达53%。 三是具备数据积累场景优势。一名行 ...
