Geekom Mini-Air 11

Pregame Show

I thought this would be a good gaming alternative - unlike SBCs this is a mini computer so has all the I/O ports you need, SD card reader, and expandable SSD and DRAM slots inside. This machine has built in wireless, JasperLake GPU, and 4 core Celeron M5105 @ 2GHz. It does run hot though; and takes 19V 3.42A 65W power (like some Chromebooks). I zapped it with my temp gun, and its 110F (43C), and its "rated" for 50C - with NO load.

WSL2 Failure

I tried to use WSL2 server, and after a couple hours gave up, as it seems set for Wayland not X11. It would be more useful if you could install Xubuntu; maybe you can but I gave up. (Linux support is something Chromebook does right.)

Windows 11 Must Die

I installed MAME and other tools and they stuttered. This can't be right, I thought. So given my WSL failure, and that I had to hunt down some older directX kits to get anything working, I said to heck with it - I must install Ubuntu 22 and benchmark with somewhat more apples to apples.

Installing Ubuntu Pains

Yes, you hit del to enter BIOS and set the startup device. Using EFI, I had to set to boot from "USB KEY". I had to blow away /dev/sda2 and other Windowsy partitions. I had to reformat the partition in ext4... and it seems the drivers on Xubuntu 22.04 image are not fully compatible with the Air Mini. (The RealTek 8821c driver continue to blow kernel errors, frame errors, and hung several times during install.) After several attempts, and update/upgrades, I managed to get Xubuntu installed and up-to-date/stable. I really don't know why Geekom doesn't have a working image, or sell the devices without Windows...

Quelle Surprise

Even though it only has 4 cores, the rendering capability of the device is solid.
  • geekom-miniair-11: 1378 ($150)
  • opi5: 975 ($110)
  • odroid n2l: 509 ($70)
So graphics from JSL makes this device 2.7x faster than my N2L, and 1.4x faster than the OPi5 (note not all benches were faster). But, sound emulation is multi-threaded and runs on multiple cores, so the next benches will be more interesting... yay symetric multi-processing.
