Compact barebone for office and media

The GMKtec G3 S-Black is a new mini PC barebone built around an Intel Celeron N95 processor with four cores and four threads that burst to 3.4GHz. It arrives with 8GB of DDR4 memory already installed and a 256GB M.2 SATA SSD for the operating system and everyday files.

Expansion limits of the storage interfaces

Two internal M.2 slots provide room to grow: a 2280 PCIe Gen3 socket that accepts drives up to 8TB and a 2242 SATA 3.0 socket that supports up to 1TB. External connectivity relies on USB 3.2 ports, dual HDMI 2.0 outputs, Gigabit Ethernet, WiFi 5 and Bluetooth 5.0 for peripherals and network links.

Headroom for multitasking and 4K playback

The 8GB DDR4 configuration handles typical office workloads, web browsing and 4K video decoding with AV1 support, while dual 4K@60Hz display output suits multi-screen setups. Memory cannot be expanded beyond the installed 8GB, so heavier virtualization or large dataset work will exhaust the available RAM.

Questions about this item

Should I pick the 8GB RAM / 256GB SSD model or the 16GB RAM / 512GB SSD version?

The 16GB / 512GB unit ships with double the memory and storage, giving more headroom for multitasking and larger media libraries without needing an immediate upgrade.

What does the N95's 3.4 GHz burst speed actually deliver in daily use?

The four-core Alder Lake chip reaches 3.4 GHz on short bursts, so office apps, web browsing and 4K video playback stay responsive while the 6 MB cache keeps latency low.

How fast is the M.2 2280 PCIe Gen3 slot in practice?

The slot runs at PCIe Gen3 speeds, so an installed SSD will hit the throughput ceiling of that generation; the second M.2 2242 slot uses SATA 3.0 for additional capacity.
