ASUS announced its RTX Spark-powered ProArt mini PC at Computex on June 1, 2026, and said availability would begin in fall 2026 in select regions. ASUS’s product page identifies the system as the ProArt GR1X, powered by the NVIDIA RTX Spark N1X. The company’s announcement and GR1X specifications put the compact desktop in the local-AI and creative-workstation category.
The GR1X is the compact-desktop member of the RTX Spark platform, also covered in our earlier report on NVIDIA’s RTX Spark systems.
What ASUS lists for the GR1X
ASUS lists a 20-core NVIDIA Grace CPU and a 6,144-core NVIDIA Blackwell RTX GPU, paired with 64 GB or up to 128 GB of unified LPDDR5X memory. Here are the main specifications on the GR1X product page:
| Specification | ASUS-listed details |
| Platform | NVIDIA RTX Spark N1X |
| CPU | NVIDIA Grace, up to 20 cores |
| GPU | NVIDIA Blackwell RTX, up to 6,144 cores |
| Memory | 64 GB or up to 128 GB unified LPDDR5X, shared by the CPU and GPU |
| Dimensions and weight | Approx. 5.9 × 5.9 × 2.0 in; approx. 67 in³; 3.26 lb |
| TDP and power supply | 140 W TDP; separate 240 W power supply |
| Networking | 10G Ethernet, Wi-Fi 7 2×2, Bluetooth 5.4 |
| Video and USB | HDMI 2.1; four USB-C ports, three with DisplayPort alternate mode and one for power input; support for up to four displays |
| Operating system | Windows |
The 128 GB figure is unified system memory, not a separate 128 GB pool of video memory. The CPU and GPU share it. And the two power numbers describe different things: 140 W is the listed TDP, while 240 W is the power supply’s rating.
The workloads ASUS promotes
ASUS advertises up to 1 petaflop of FP4 AI performance, local operation of language models with up to 120 billion parameters, and context windows of up to one million tokens. It also promotes rendering 90 GB 3D scenes, editing 12K 4:2:2 video, and gaming at 1440p above 100 frames per second. These are ASUS’s stated capabilities; the company describes performance figures as theoretical unless otherwise noted and says real-world results may vary.
That mix explains the GR1X’s pitch: a compact desktop for local AI alongside rendering, video work, and gaming. The advertised figures provide a sense of the workloads ASUS is targeting, while actual results depend on the task and configuration.
ASUS’s June announcement set a fall 2026 availability start for select regions; it did not give a country-specific date in that release.
