骁龙778G

2021年高通公司发布的芯片

骁龙778G是高通公司于2021年5月18日发布的5G移动平台。

发展历程

高通公司于2021年5月18日推出了基于6纳米工艺技术的骁龙778G 5G移动平台，扩展其7系列产品组合。

简要概述

影像

骁龙778G支持三ISP，可同时拍摄三张照片或三个视频，包括广角、超广角和变焦。用户可以同时通过三个镜头进行视频录制，不仅每个镜头可以捕捉最佳效果，还能自动将三个画面合成为一支专业品质的视频。用户还可以如专业摄影师一般拍摄4K HDR10+视频，捕捉超过10亿色。骁龙778G还支持单帧逐行HDR图像传感器，从而用户可以利用计算HDR赋能的视频拍摄，获得色彩、对比度和画面细节方面的显著提升。

骁龙778G支持全新的第六代高通AI引擎包括高通Hexagon™ 770处理器，可带来高达12TOPS的算力，性能较前代平台实现翻番，且每瓦特性能得到提升。AI为几乎所有的连接体验、视频通话和语音通话提供加持，比如基于AI的噪音抑制、更出色的基于AI的影像用例等。第二代高通传感器中枢集成的专用低功耗AI处理器能够支持情境感知用例，进一步增强了该平台的性能。

游戏

该平台支持部分高通Snapdragon Elite Gaming™特性，包括可变分辨率渲染（VRS）和高通Game Quick Touch，这两项特性已在骁龙7系平台中实现支持。凭借高通Adreno™ 642L GPU，VRS让开发者能够在不同的游戏场景中指定和分组被着色的像素，以减少GPU的工作负载，从而在保持画面最高的视觉逼真度的同时降低功耗。高通Game Quick Touch将触控响应速度提升20%，降低触控时延的同时，带来专业级游戏体验。

连接

骁龙778G集成骁龙X53 5G调制解调器及射频系统，可为全球更多用户带来毫米波和Sub-6GHz频段5G连接能力。通过高通FastConnect™ 6700移动连接系统，骁龙778G支持数千兆比特级的Wi-Fi 6速度（高达2.9Gbps）和4K QAM，并在5GHz和6GHz频段支持160MHz信道。此外，由高通技术公司认证的高通Snapdragon Sound™技术套件采用先进的音频特性及系统级优化，可实现全新的端到端聆听体验。凭借蓝牙5.2、极速的Wi-Fi 6/6E和5G连接，骁龙778G能够为游戏、分享和视频通话等场景带来低时延表现。

性能

骁龙778G采用先进的6纳米工艺制程，能够提供出色的性能和能效。高通Kryo™ 670 CPU整体性能提升高达40%。Adreno 642L GPU的图形渲染速度较前代平台提升高达40%。
