Asus has launched the ROG GR70, a gaming mini-PC that squeezes a desktop-level powerhouse into a case under 3 liters in volume. This isn’t just a compact PC for basic tasks-it pairs a mobile Ryzen 9 9955HX3D processor with an Nvidia GeForce RTX 5070 Laptop GPU, delivering serious gaming muscle without a bulky discrete graphics card.
The GR70 uses AMD’s mobile platform alongside Nvidia’s laptop-grade RTX 50 series graphics, which explains how Asus achieved such a tiny footprint. The external 330W power brick handles the juice, while the chassis measures just 282.4 × 187.7 × 56.5 mm, translating to about 2.99 liters-right at that coveted ”under 3 liters” mark.
At the top end, the mini-PC features the Ryzen 9 9955HX3D, a 16-core chip equipped with AMD’s 3D V-Cache technology aimed at boosting game performance. Other available CPUs include the Ryzen 9 9955HX and the Ryzen 9 8940HX. Cooling hasn’t been sacrificed for size, either: Asus’s ROG QuietFlow system packs three fans and heat pipes to keep temperatures in check inside this tightly packed case.
Asus ROG GR70 mini-PC specifications
- Processors: Ryzen 9 9955HX3D, Ryzen 9 9955HX, or Ryzen 9 8940HX
- Graphics: GeForce RTX 5070 Laptop GPU or RTX 5060 Laptop GPU
- Memory: DDR5-5600, up to 32GB in confirmed models
- Storage: 1TB PCIe 4.0 SSD
- Power: 330W external adapter
- Operating System: Windows 11 Home
Two configurations are launching:
- Flagship: Ryzen 9 9955HX3D, GeForce RTX 5070 Laptop GPU, 32GB DDR5-5600 RAM, 1TB SSD – priced at €3,478
- Entry-level: Ryzen 9 8940HX, RTX 5060 Laptop GPU, 16GB RAM, 1TB SSD – priced at €2,888
These prices are steep compared to traditional gaming desktops but make sense given the form factor and factory assembly. Last year’s Asus ROG NUC, which combined Intel Core Ultra processors and an RTX 4070 Laptop GPU, similarly pushed the boundaries of ultra-compact gaming PCs at a premium price. Dimension-wise, the GR70 easily outshines the Mac Studio, which clocks in around 3.7 liters but isn’t geared for gaming.
What sets the ROG GR70 apart is its blend of size, power, and convenience-delivering a rare combo of desktop-grade gaming performance in a prebuilt, ultra-compact chassis without the hassle of building a mini-ITX system yourself.
As gaming mini-PCs continue to shrink without compromising performance, it will be interesting to see if Asus and others push even smaller volumes or integrate newer GPU architectures. The ROG GR70 raises the bar for what a mini-PC can handle, but the relentless quest for more power per cubic inch is far from over.
