Beelink Sei12 Pro – Performance
Beelink SEi 12 has the latest 12 Gen Intel 1240P CPU. P category CPUs are mid-range products and have the performance between H and U series processors. It is not a laptop-grade processor, so we can expect excellent performance in CPU-oriented tasks. Moreover, both memory and storage are mid-range because of the price.

Things are not the same when it comes to graphic-intensive tasks. But you can add graphics power through the thunderbolt 4 port, which is an exceptional addition.

Overall, the mini PC is a great performer at this price and has much to offer regarding CPU performance. If you want extra graphics, then hook up an additional GPU through the thunderbolt 4 port on the front.
Upgradability and Repairability
Most mini-PCs are not upgradable or very hard to upgrade because of their intricate design and components soldered to the motherboard. Beelink SEi12 is built differently. The bottom flap comes off easily, giving you access to the upgradable parts like RAM and SSD.
Moreover, it also has an HDD slot, allowing you to add more room for storage.
Drawbacks
- Outdated BIOS
- Lack of Accessories to order
- Slow NVMe SSD
Verdict
At a price, Beelink SEi12 is an excellent performer. It has mediocre parts, and performance is not high-end, but the computer is fantastic for multimedia, great for office work, and fine with less graphic-intensive games.
Moreover, the ability to easily upgrade some performance parts and connect with external GPUs makes it an excellent device for all sorts of users.
