UP Board performance compared to ARM

Recommended Posts

Just to have some sort of comparison to x86 based SBC I benchmarked my UP Board (lying in the drawer for years) right now:

 

As can be seen the Intel Atom x5-Z8300 CPU will be outperformed by an RK3399 or even an el cheapo NanoPi Fire3 pretty easily: https://github.com/ThomasKaiser/sbc-bench/blob/master/Results.md

 

Onboard eMMC performance (16GB on my model) also not that impressive (random IO ok, but sequential write performance below SD card level at just ~20 MB/s):

Internal 32 GB eMMC                                           random    random

I backed this board in the beginning to check it with NAS usage in mind but never managed to attach fast storage since UP Board (just like LeMaker's Guitar back then) uses the crappy Micro-B USB3 receptacle (designed for OTG/device and not host mode -- you need an UEFI update and a special cable to be able to attach USB3 SuperSpeed peripherals to this board).

 

BTW: kernel situation as crappy as with a lot of ARM boards (or maybe the board now fully works also with mainline kernel -- I don't know). At least the official kernel enabling majority of board features is a 4.9.45 that received zero fixes for over a year now: https://github.com/emutex/ubilinux-kernel
