Beelink SER3 Benchmark Summary

As you can see the 16GB model outperformed the 8GB model by a fair margin. With 7% difference on PassMark, 3% on PCMark and 9% on 3DMark.

Despite having the same processor, the extra performance found on the Beelink SER3 16GB RAM help give a decent boost with up to 9% difference. This can be a noticeable difference with your day to day tasks from booting up windows, running software, through to loading and saving large documents for example. It is definitely enough of an increase in performance to make the 16GB model the one to choose!
