2026 verdict
Same brand, different class of mini PC: the GMKtec NucBox M2 Pro S (16GB + 1TB) rates higher with owners and doubles both the memory and storage of the GMKtec NucBox G3S (8GB + 256GB).
Where the G3S leans on an entry-level Intel N95 with a single 8GB stick of DDR4, the M2 Pro S runs a mobile Core i7-1185G7 with 16GB of dual-channel memory and a full terabyte of storage, a meaningfully faster machine for everyday multitasking. The G3S answers back with a lower price, which keeps it relevant for buyers who only need a browser and a spreadsheet. Both come with a VESA mount and an HDMI cable in the box, and neither locks you into a fixed configuration since both accept aftermarket memory and storage. If the budget allows it, the M2 Pro S is the more capable everyday desktop; if the budget is the whole point, the G3S still gets the job done.

Frequently Asked Questions
Which is better overall: GMKtec NucBox G3S (8GB + 256GB) or GMKtec NucBox M2 Pro S (16GB + 1TB)?
The GMKtec NucBox M2 Pro S (16GB + 1TB) is the better all-round pick, with a higher owner rating and double the memory and storage capacity of the GMKtec NucBox G3S (8GB + 256GB). The G3S wins only on price.
What is the biggest difference between the GMKtec NucBox G3S and the GMKtec NucBox M2 Pro S?
The processor generation and the storage. The G3S uses an entry-level four-core Intel N95 with a 256GB drive, while the M2 Pro S uses a four-core, eight-thread Intel Core i7-1185G7 with a 1TB drive, a much stronger chip paired with far more room for files.
Can you upgrade the memory on either machine?
Yes. The G3S has a single DDR4 SO-DIMM slot capped at 16GB, while the M2 Pro S has two DDR4 SO-DIMM slots and can reach 64GB, giving it far more room to grow.
How many monitors can each one drive?
The G3S drives two 4K displays over its dual HDMI 2.0 ports. The M2 Pro S drives three displays, adding a Type-C port with DisplayPort output alongside its two HDMI 2.0 ports.

Who should buy the GMKtec NucBox M2 Pro S?
Buyers who want a genuine Core i7 for everyday multitasking, triple-monitor output and a full terabyte of storage out of the box.
