Beelink SER3 mini PC review: The older Ryzen 7 3750H has its uses
Beelink carries several mini PCs powered by older Intel and AMD CPUs as cheaper alternatives to the newest Intel NUCs powered by the latest generation of processors. Nearly all HTPC applications ranging from web browsing to 4K video streaming don't require the fastest and greatest CPUs which mean most users can get away with less expensive hardware.
Our Beelink SER3 test unit comes equipped with the two-year old AMD Zen+ Ryzen 7 3750H CPU that has since been replaced by the newer Zen 2 4000H and Zen 3 5000H series.

Case
The chassis is mostly matte metal with a bit of glossy plastic on the front and part of the top. First impressions are strong albeit not as rigid as an Intel NUC which utilizes thicker and heavier metal materials.
Connectivity
Port options are exactly the same as on the Beelink SEi10. However, keep in mind that there is no Thunderbolt on the SER3 since its AMD CPU does not natively support the interface.
The USB-C port supports DisplayPort-out, but it would strangely only work with some and not all of our external monitors.

Maintenance
The bottom panel can be easily removed with just a Philips screwdriver to reveal a removable WLAN module, removable M.2 2280 NVMe SSD, and 2x SODIMM slots.
Accessories and Warranty
The retail packaging includes two short HDMI cables, a 50 mm or 100 mm mounting bracket, and extra screws in addition to the usual manual and AC adapter. A one-year manufacturer warranty applies
Performance
Testing Conditions
Our unit was set to Performance mode prior to running any benchmarks below for the highest possible scores.
Processor
Raw CPU performance is comparable to the Core i5-8259U in the competing GMK NucBox 2. It doesn't quite reach the performance of newer Zen 2 or Tiger Lake U-series CPUs like the Ryzen 7 5700U or Core i5-1135G7 commonly found on the latest Ultrabooks. Performance when under high loads for long periods is consistent nonetheless with no major throttling issues.

Storage Devices
Whereas our SEi10 comes with a 256 GB Silicon Motion AZW NVMe SSD, our SER3 comes with the 512 GB version instead. Sequential read and write rates reveal the drive to be a midrange NVMe offering. Transfer rates will slow over time when stressed from 1900 MB/s to 1400 MB/s or slower due to thermal limitations. Many Intel NUCs integrate a heat spreader on top of the NVMe SSD for cooling to prevent or delay the performance slowdown.

GPU Performance
Graphics performance is most similar to the Iris Plus Graphics 655. While our Radeon RX Vega 10 is a decent upgrade over the UHD Graphics 620, it's still significantly slower than the latest Iris Xe NUC options from Intel. Overall performance is slightly slower than the average RX Vega 10 in our database because our SER3 test unit comes with single-channel RAM only. Users can squeeze more performance from the GPU if configured with dual-channel RAM.
