The Core Spec Sheet
ASUS's product page says the GR1X puts a 6144-core NVIDIA Blackwell RTX GPU and 20-core NVIDIA Grace CPU into one NVIDIA RTX Spark Superchip, delivering up to 1 petaflop of FP4 AI performance and up to 128GB of unified memory.
Keep in mind that the 1-petaflop figure is measured at FP4, a very low-precision format used for AI inference. It doesn't tell you much about general compute speed or gaming frame rates.
Notebookcheck noted that the GR1X will only be available with the 20-core CPU and 6,144-core GPU variant of the RTX Spark N1X. Based on NVIDIA's own listings, the publication said the lesser 18-core CPU and 5,120-core GPU variant will be exclusive to RTX Spark-powered laptops. Buyers therefore won't be choosing between silicon tiers. ASUS's global tech-spec page lists LPDDR5X memory at up to 128GB of Shared High-Bandwidth Unified Memory, with 64GB configurations also on offer.
Storage is where the configurations differ most. ASUS's spec sheet lists three included SSDs:
- 1TB M.2 NVMe PCIe 4.0
- 2TB M.2 NVMe PCIe 4.0
- 4TB M.2 NVMe PCIe 5.0
All of them sit in a Dual SSD, M.2 NVMe PCIe 5.0 / 4.0 SSD storage slots, Up to 4TB layout. One detail is easy to miss: on that listing, only the 4TB option uses PCIe 5.0. If drive speed matters for your work (scratch disks, big datasets), the storage tier also changes the drive generation.
Operating system: The same spec page lists Windows 11 Pro Windows 11 Home, which matches ManilaShaker's report of Home and Pro configurations. Which edition you can actually get will likely depend on region and SKU. For small offices that need BitLocker management, Group Policy or domain/Entra join, picking Pro over Home matters more than any shell color.
In short: there is one chip option, two memory sizes (64GB or 128GB) and three storage tiers, with Windows 11 Home or Pro depending on the SKU.
Ports, Networking and Power
The I/O is small but well chosen for this size of machine:
| Port / Feature | Detail |
|---|---|
| USB-C (display) | 3 × USB 3.2 Gen 2×2, 20Gbps, DisplayPort Alt Mode |
| USB-C (power in) | 1 × USB 3.2 Gen 2×2 with PD input (EPR PD 3.1) |
| Video | 1 × HDMI 2.1 |
| Wired network | 1 × 10G RJ45 |
| Wireless | Wi-Fi 7 2×2, Bluetooth 5.4 |
| Security | Kensington lock slot |
ASUS says you can support up to four 4K displays, using the HDMI port plus the three DisplayPort-capable USB-C ports. ASUS doesn't say which resolution and refresh-rate combinations work when all four are connected, so don't plan a quad-display setup until someone tests it.
Power is the unusual part. Notebookcheck reports that ASUS confirmed the mini-PC will ship with a 240 W USB Type-C PSU in compliance with Power Delivery 3.1 EPR specifications. The machine is powered over USB-C rather than a barrel jack. That's tidy, but it's also a warning: an ordinary 100W laptop charger almost certainly won't run this system under load. Use the bundled 240W brick or a certified EPR replacement.
Notebookcheck also points to a 140 W TDP, a figure that appears on ASUS's own product page as well.
In short: this is a USB-C-powered machine with 10GbE, Wi-Fi 7 and four display outputs. Plan for a 240W EPR power source.
Small Box, Two Fans
The chassis is 150 × 150 × 51mm, and Notebookcheck put the weight at 1.48 kg (~3.26 lb) with a ~1.1-litre case volume. That's heavy for its size, and probably a sign of how much heatsink is inside. Gizmochina reports that to manage the 140W TDP of the internal components, Asus uses a dual-fan cooling system and a vented chassis design. ASUS says the thermal setup is engineered for continuous 24/7 operation, supporting background AI tasks and long rendering sessions.
ASUS's own page describes twin 140 × 80mm fans with 109 blades each, four heat pipes and 57 fins. It claims you'll rarely notice thermal throttling at 25°C or 30°C ambient. Those are vendor claims. No independent noise, thermal or power-draw measurements are available yet. "Near-silent" in a 1.1-liter case holding 140W of silicon is a promise reviewers will want to check with a decibel meter.
The GR1X comes in two finishes. ASUS says the black version is anodized and the silver one is sandblasted to resist fingerprints.
Why Windows Users Should Care: It's an Arm PC
The spec sheet doesn't spell this out, but it matters most for Windows users. ASUS's East Africa product page puts it under the heading Windows on ARM: Familiar Feel, Next-Gen Power. NVIDIA's Grace CPU uses Arm cores, so the GR1X runs Windows on Arm, not x86 Windows.
From general industry knowledge, that has practical consequences:
- Native Arm64 apps run at full speed, and the list has grown a lot since the early Windows on Arm years.
- x64 apps generally run through Microsoft's Prism emulation layer. Most work, but with some performance cost.
- Kernel drivers and anti-cheat are still the weak spots. Older hardware peripherals, some VPN clients, and games with kernel-level anti-cheat can fail if there's no Arm64 driver.
- Enterprise tooling such as endpoint agents, management clients and security software should be checked for Arm64 support before deployment, not after.
ASUS markets gaming capability (ray tracing, DLSS, Reflex), and NVIDIA supplying the GPU driver helps. But the game library on Arm is a different question from what the GPU can do. Check your specific titles before assuming the GR1X can replace a gaming PC.
In short: this is a Windows on Arm machine with a powerful NVIDIA GPU. Most software will run, but check drivers, anti-cheat and enterprise agents first.
GR1X vs. ASUS's Own Ascent GX10
If this sounds like the DGX Spark-class developer boxes, ASUS addresses that in its FAQ. The company says the GR1X is built for creators who want local AI agents running inside everyday Windows workflows such as Adobe apps and CapCut. The Ascent GX10, by contrast, is a Linux-based developer workstation running DGX OS, positioned as a personal AI supercomputer.
The hardware differs too. In an analysis comparing the two platforms, developer blogger YASUO-JP noted that the high-end RTX Spark N1X and DGX Spark GB10 have similar published specifications, but they are not the same chip. The same post points out that ASUS ProArt GR1X is equipped with 10GbE, but ConnectX-7 and QSFP ports are not listed in the specifications. If you were hoping to cluster several units over high-speed interconnects the way DGX Spark owners do, the GR1X isn't designed for that.
The AI Claims, Qualified
ASUS says it can handle 120B-parameter language models locally. Gizmochina relays the company's claim that the 128GB variant can run large language models with up to 120 billion parameters entirely on-device, without relying on cloud processing. ASUS also cites 3D scenes of more than 90GB and AAA gaming at 1440p and above 100 fps.
ASUS's own FAQ makes the LLM claim depend on model architecture, precision, context length and whatever else the system is running. Read that as "a heavily quantized 120B model, with a lot of headroom given up." The 64GB model is a very different proposition for large models. Neither claim has been independently benchmarked yet.
The bundled software includes ASUS's ProArt Creator Hub, StoryCube and MuseTree apps, validated ComfyUI workflows, an ASUS agent tool called Zenni Claw, and a three-month Adobe Creative Cloud subscription.
Price and Availability
ASUS's US product page still says "Coming soon." The company's US press release says the ProArt GR1X will be available later this year, mainly in advanced configurations (64GB and 128GB), through select premium retailers. That release is titled as a pre-order announcement for the ProArt RTX Spark PCs. Those pre-orders appear to cover the new ProArt laptops, and the GR1X gets only the "later this year" window.
ManilaShaker's statement that ASUS hasn't given pricing or availability is therefore mostly right. There's a broad 2026 window, but no price and no ship date. How well this machine competes, including against the Mac Studio comparisons Notebookcheck raised, will depend heavily on the price.
The Bottom Line
The GR1X is ASUS's most direct attempt yet at a small, always-on local-AI box that runs Windows. What's confirmed is solid: a 1.1-liter chassis, up to 128GB of unified memory, 10GbE, dual M.2 slots, quad-display output and 240W USB-C power. What's missing is price, independent benchmarks, measured noise levels, and a clear picture of app and driver compatibility under Windows on Arm.
If your work involves local inference, generative media or large 3D scenes, it's one to watch. If your work depends on x86-only drivers or kernel anti-cheat games, wait for the reviews.
