高通昨晚毫无预警发布了新款 8 系列芯片——高通骁龙 870 （下称“870”）。

虽然看似是一款全新的产品，不过 870 基本可看作是 865+ 和 865 的马(yá)甲(gāo)版，保留了大部分的特性，包括同样采用 7nm 工艺制程，八核心三丛架构，主要主频从 865+ 的 3.1GHz 微幅提(chao)升(pin)到 3.2GHz。透过外挂 X55 基带方式支持 Sub-6GHz和 mmWave 的 5G 频段
然而，870 并非如高通所形容的“骁龙865 Plus移动平台的升级产品”。根据官网上的信息，870 并不支持 Wi-Fi 6E 连接，同时对比 865+ 也少了 Quick Charger 5 快充协议的支持。在这两点上 870 和 865 保持一致，支持 Wi-Fi 6 及 Quick Charge 4+ 协议。
870 在 865+ 及 865 的差异让这款新品的定位相当模糊，也容易令人产生混淆，不少外媒都将之戏称为”865++”，小编个人更愿意将 870 看作是 865 的超(ya)频(gao)版而非 865+ 升级款。
高通在新闻稿上表示搭载高通骁龙 870 的产品将在 2021 年第一季度亮相。就 Motorola、 iQOO、 OnePlus、 OPPO 及 Xiaomi 的高层纷纷现身背书，相信这几个品牌短期内将会推出采用这款“新”处理器的 “Lite” 版本旗舰手机吧~
