Beelink SEi8 Intel Core i5-8259u Performance review

Awesome mini pc for home office! this mini pc is fast enough to run home office programs, this mini pc comes with windows 10 already installed. It supports 4K at 30 Hz dual screen and dual display, it comes with 4 USB 3.0 and 1 type C thunderbolt too! it supports linux operating system like Ubuntu for example!

 It is small about the size of two decks of playing cards. It supports 4k. It has USB and USB-C ports. We affixed it to the back of a 4K TV, ran the included HDMI cable (was not expecting one) from the PC to the HDMI port of a Samsung TV, set up Windows, and plugged in a USB-c Logitech webcam into the PC. It handles this task perfectly. No more finding a laptop and plugging it into the TV. 

 It also does a great job with cloud gaming (via Stadia) and although it’s not the ultimate gaming PC since it lacks a dedicated GPU, my Sei8 handled Steam games with a nearly perfect framerate. I had no issues streaming to Twitch using a USB webcam, my Xbox via a USB capture card, and a mic/headset combination, but here is where I needed to use a USB hub in order to accommodate all of the necessary peripherals.
