What the differences mean

Graphics and AI

The Asus ROG GR70 has a discrete RTX 5070 Laptop GPU with 8GB, built for gaming and GPU rendering. The GMKtec NucBox K13 relies on Intel Arc 140V graphics but adds a 47 TOPS NPU the Asus ROG GR70 lacks, so the two excel at different jobs.

Processor

The Asus ROG GR70 runs a 16-core, 32-thread Ryzen 9 9955HX for heavy multitasking and gaming. The GMKtec NucBox K13 runs an eight-core Intel Core Ultra 7 256V, tuned for efficiency rather than peak throughput.

Memory

The Asus ROG GR70 ships 32GB of DDR5-5600 in SO-DIMM slots that reach 96GB. The GMKtec NucBox K13 has 16GB of LPDDR5X-8533 soldered, faster per transfer but half the size and not upgradeable.

Storage

The Asus ROG GR70 includes a 2TB PCIe 4.0 drive, four times the 512GB in the GMKtec NucBox K13. Both use M.2 2280 slots that can be expanded.

Power and size

The Asus ROG GR70 needs a 330W external adapter and weighs 2.75 kg. The GMKtec NucBox K13 uses a 100W adapter and weighs about 523 g, so it is the one that disappears behind a monitor.

Display outputs

The Asus ROG GR70 drives five displays through two HDMI 2.1, two DisplayPort 2.1 and a USB4 port. The GMKtec NucBox K13 drives up to three through one HDMI 2.1 and two USB4 ports.
