先下载对应版本的 Miniforge3, ====> OS X arm64 (Apple Silicon)

装上之后就有 conda 了,conda 里面装 numpy,scipy 什么的都是原生的

性能提升很大 无论对比 Rosetta 2 还是 intel i9

想知道对比 Intel i9 mkl 版 numpy 提升多少……

找到了个 numpy 性能脚本 跑了一下 https://gist.github.com/markus-beuckelmann/8bc25531b11158431a5b09a45abd6276

```
Dotted two 4096x4096 matrices in 0.53 s.
Dotted two vectors of length 524288 in 0.25 ms.
SVD of a 2048x1024 matrix in 0.59 s.
Cholesky decomposition of a 2048x2048 matrix in 0.08 s.
Eigendecomposition of a 2048x2048 matrix in 4.74 s.

This was obtained using the following Numpy configuration:

library_dirs = ['/Users/yux/miniforge3/envs/maths/lib']
include_dirs = ['/Users/yux/miniforge3/envs/maths/include']

p.s. python 版本 3.9.1 -arm64 跑的时候关掉了所有后台

@YUX Thx 这是我 16 寸 MBP i9 款跑出来的结果。没有关后台。环境 anaconda 3.8 。看上去比 M1 还是快一点的。（不然 Intel 真的要哭）

M1:Dotted two vectors of length 524288 in 0.25 ms
MBP16:Dotted two vectors of length 524288 in 0.05 ms.
这一项差的好多啊。

@pb941129 不错还是 i9 强😂 是不是跑的时候 8 核 16 线程都占满了

@changepc90 这应该就是指令集差异造成的叭

T480s 上的 i7 8550u，库是 mkl_rt

Dotted two 4096x4096 matrices in 1.07 s.
Dotted two vectors of length 524288 in 0.13 ms.
SVD of a 2048x1024 matrix in 0.53 s.
Cholesky decomposition of a 2048x2048 matrix in 0.15 s.
Eigendecomposition of a 2048x2048 matrix in 5.07 s.

用 HWMonitor 读出来 8550u 的实时功耗大概在 40-45W，M1 应该才 20W 吧（悲

@YUX 没看任务，不过以我对 numpy 尿性的理解，不至于不至于。可以等 lightgbm 适配了然后一起跑跑 CPU 版本（当时跑一个小项目找最优参数跑满整个 8700k 三小时

@sxd96 感觉心里平衡了一点点，也是没关后台，mkl 库。但是我发现在核心满负载的情况下，MBP 会有一点点电啸声。虽然现在 ARM 在这上面可能差了一点点，但是如果算能效比，可能并不差。我觉得移动设备重要的还是能效比。
