MSI has introduced a new compact PC. "EdgeMesa N AI+," as MSI calls it, features NVIDIA's new RTX Spark N1X platform in the form of a 20-core Grace CPU and a Blackwell GPU, paired with up to 128GB of LPDDR5X unified memory. The system brings NVIDIA's latest AI-focused hardware to a compact desktop form factor running Windows 11.
RTX Spark is NVIDIA's new platform for Windows laptops and compact desktops, pairing Grace Arm CPU cores with Blackwell RTX graphics and unified memory. At the top end, the N1X configuration offers a 20-core CPU, a 6,144-core Blackwell GPU, and up to 128GB of LPDDR5X memory.

While the hardware is similar to NVIDIA's DGX Spark AI workstation, RTX Spark targets a broader Windows audience, with support for gaming, content creation, and local AI workloads. So MSI has not simply built another AI box. Instead, NVIDIA is repurposing the GB10 architecture as a proper Windows desktop platform.
The EdgeMesa N AI+ can be configured with up to 128GB of LPDDR5X unified memory and 4TB of NVMe storage. At its core is NVIDIA's RTX Spark N1X SoC (System on Chip), which pairs a 20-core Grace CPU with a Blackwell GPU featuring 6,144 CUDA cores. NVIDIA rates the configuration at up to 1 PetaFLOP of FP4 AI performance.
Interestingly, the integrated Blackwell GPU carries around 4% more CUDA cores than NVIDIA's GeForce RTX 5070 Ti Laptop GPU, which features 5,888 cores. However, that does not make them directly comparable, due to differences in power limits, clock speeds, bandwidth, and thermal headroom.
Despite its compact form factor, the EdgeMesa N AI+ packs a comprehensive selection of connectivity options, including four USB Type-C ports supporting speeds of up to 20Gbps, HDMI 2.1b, 10Gb Ethernet, Wi-Fi 7, and Bluetooth 5.4. MSI also equips the system with a vapor-chamber cooling solution and fan to handle the RTX Spark N1X platform within its 140W power envelope.
Although it shares much of its underlying hardware with DGX Spark, MSI's mini-PC drops the latter's 200Gbps ConnectX-7 networking, which NVIDIA uses to link multiple DGX Spark systems for running larger AI models. DGX Spark also officially runs NVIDIA's Linux-based DGX OS, whereas RTX Spark is designed around Windows 11 support.

In any case, NVIDIA RTX Spark N1X systems are expected to begin shipping in October 2026. MSI has yet to announce an exact launch date or pricing for the EdgeMesa N AI+. Even so, with hardware closely resembling DGX Spark, we wouldn't expect it to be cheap, as NVIDIA currently lists its own DGX Spark at $4,699.
