For a Pi, you can even change the memory split if dont use any graphical desktop features etc:

> gpu\_mem
> 
> Specifies how much memory, in megabytes, to reserve for the exclusive use of the GPU: the remaining memory is allocated to the ARM CPU for use by the OS. For Pis with less than 1GB of memory, the default is 64; for Pis with 1GB or more of memory the default is 76.

[https://www.raspberrypi.com/documentation/computers/config\_txt.html](https://www.raspberrypi.com/documentation/computers/config_txt.html)

Run `sudo raspi-config` and select:  
Performance Options --\> GPU Memory

I've just just now as an experiment changed it into 16MB.  
Before:

```auto
pi@ph5a:~ $ free -h
              total used free shared buff/cache available
Mem: 176Mi 38Mi 51Mi 2.0Mi 86Mi 88Mi
Swap: 99Mi 41Mi 58Mi

```

After:

~~ 

```auto
pi@ph5b:~ $ free -h
               total used free shared buff/cache available
Mem: 477Mi 43Mi 317Mi 3.0Mi 116Mi 381Mi
Swap: 99Mi 0B 99Mi

```

 ~~

Wrong Pi, below is correct one:

```auto
pi@ph5a:~ $ free -h
              total used free shared buff/cache available
Mem: 224Mi 38Mi 56Mi 5.0Mi 129Mi 132Mi
Swap: 99Mi 0B 99Mi

```

```auto
pi@ph5a:~ $ cat /boot/config.txt
[..]
gpu_mem=16

```
