NucBox G3 – Performance
GMKtec NucBox G3 has a capable N100 processor. The 12th Gen processor has really up the game for mini-PCs. It consumes really low power and delivers fairly good performance. In idle mode, it only consumes 10 watts which is equal to 2 small LED bulbs.
NucBox G3 has DDR 4 RAM, yes, the processor is capable of running DDR 5 but we all know DDR 5 RAM is significantly expensive. The PC can hold up to 16GB of single-channel memory. It also has a single slot of SSD that can accommodate up to 2TB NVMe M.2 storage. Moreover, unlike Beelink SER5 it lacks a 2.5-inch HDD port as well. I also like the fact that GMKtec has gone with a TLC-based storage in a low-budget device whereas most manufacturers choose to go for inferior QLC models. TLC delivers better, stable, and sustainable performance.
So, overall NucBox G3 has a solid, power-efficient processor, fast RAM, and reliable storage.
The mini-PC is running the latest Windows 11 Pro. It comes pre-licensed which is unbelievable for that affordable computer. There are tons of customization options and I am getting consistent updates.
Office Tasks
The mini-PS handles office tasks quite elegantly. Documents, emails, reports, presentations everything works fine. If you want to use it for multimedia, the performance is equally good. It supports all the codes on the hardware level and you can stream practically everything.

Gaming

A surprising thing was the fan noise was hardly noticeable during high-power gaming sessions.
Connectivity
Internet connectivity is excellent as well. You get all the wireless connectivity protocols on top of a 2.5 Gigabit LAN. So, no matter if choose wired or wireless, the great performance is a constant in the case of NucBox G3. Moreover, Bluetooth 5.2 is great for wirelessly connecting peripheral devices.
Upgradability and Repairability
Upgrades are quite simple as we have on almost every Mini-PC except Mac mini. You can upgrade the RAM and storage but access to the Wi-Fi module and processor is not possible. You can upgrade the RAM up to 16GB and storage up to 2TB.
Drawbacks
- Single RAM Slot
- No USB Type-C port
- No thunderbolt
Conclusion
Even with these minor drawbacks, I think it is a great device considering how much performance they were able to fit in this small package at an incredible price. GMKtec has made NucBox G3 a totally worthy device. So, what do you think let us know in the comment.
