学习AOSP安卓系统源代码，需要什么样的电脑？不同配置的电脑，其编译时间有多大差距？

1. 卷首语

俗话说得好，工欲善其事必先利其器！有一台自己的编译服务器是每个学习AOSP 安卓系统源代码人的梦想，然而需要什么样的配置呢？下面是我当前在用的3个平台的核心配置，可供大家参考。

• 因为学习安卓系统源代码，就需要编译和调试系统源码，所以需要一台性能强劲的电脑，否则将在等待上浪费不少时间
• 个人推荐系统至少是6核心12线程以上，内存至少32G，考虑价格因素搭配使用固态和机械硬盘

另外推荐个人专栏文章：

• [Android 11]使用Android Studio调试系统应用之Settings移植（一）：编译服务器的配置、AOSP源码的下载、编译、运行

2.中低配置（6000元价位）

2.1 (2019年7月)AMD Ryzen 5 2600X 6核心12线程 32GB 1TB固态

• 此套配置，之前是为了兼顾玩点小游戏，2019-07组装，CPU和显卡记得都是千元左右价位，编译时间花了3小时23分钟。
• 可改换AMD（锐龙7 5800X 8核16线程）2569.00元，或锐龙9（12核心 24线程），获取更高性能
• 因集显会和CPU抢内存资源，所以不建议使用集显，若不玩游戏，可选配500元以下低端显卡

2.1.1 系统配置

CPU： AMD Ryzen 5 2600X 6核心12线程
内存：金士顿 (Kingston FURY 16GB DDR4 3200)  x2条
主板：微星B450M MORTAR迫击炮
显卡：蓝宝石（Sapphire）RX580 2048SP 8G D5 白金版 OC 1306MHz/8000MHz 8GB/256bit
硬盘：1TB 固态硬盘

3. 中高配置（10000元价位）

• AMD 3900X（老电脑） 此套配置编译时间越90分钟，虽然配置了固态，但因固态空间较小，一般用于代码分析；编译部分依旧使用机械硬盘
• Intel i7 12700为12核心20线程，为2022年3月份新配置的电脑，对于个人使用，本人已比较满意。
• 可能部分人会去捡二手的Intel志强处理器，有功夫折腾的也可以，个人没研究这一块。

3.2 i7-12700 32GB 2TB 固态

3.2.1 2022年3月 （Intel i7-12700）

• CPU、内存、固态硬盘为个人推荐配置
• 2TB固态硬盘已基本足够用，飞一般的感觉
  

3.2.2 编译 65分钟

4. 高端及其他配置

此类一般是公司里使用，如自己组建团队，可考虑购买。

4.3 DELL R630 E5 2600 v4 36核72线程 128GB内存（二手2000+， 创业推荐）

• 遇到此机纯属意外，想到价格如此便宜，大致2000左右，加上各种硬盘配置大致不超过3000
• 虽然使用机械硬盘，但性能却是相当不错，尤其编译Android 13 AOSP本身较为耗时
• 除了体积大，是目前楼上配置中最具性价比的设备
  

4.3.1 配置

CPU : Intel® Xeon® CPU E5-2686 v4 @ 2.30GHz
内存 : 128GB

4.3.2 编译时间(01:12:30 (hh:mm:ss)

• 对比intel i5 第13代，32G内存，固态硬盘，同样的源码，大约3小时
