MSI’s EdgeMesa N AI+ puts NVIDIA’s RTX Spark N1X superchip into a compact desktop with up to 128GB of unified memory. Its two US configurations share the same processor and graphics hardware, leaving memory and storage as the main buying decisions.

For local AI workloads, memory capacity helps determine which models you can run. MSI offers 64GB or 128GB of LPDDR5X-9600 shared by the CPU and GPU.

NVIDIA’s top RTX Spark chip in a desktop

MSI builds the machine around an RTX Spark N1X superchip: a 6,144-core Blackwell RTX GPU paired with a 20-core NVIDIA Grace CPU.

MSI rates the chip at up to 1 petaFLOP of FP4 AI performance. FP4 is a low-precision number format built for AI math, and it is where that headline figure comes from. Unlike the laptop versions, the desktop chip has no listed NPU.

Persistent AI agents are the workload MSI keeps pointing at. Those run continuously, which is the kind of job that gets expensive when it runs on someone else’s servers.

If your work is local models and AI application development, the chip is the reason to buy. Spreadsheets and browsing do not need it.

64GB or 128GB of unified memory

Both versions use LPDDR5X-9600 across a 256-bit interface. The X-006US carries 64GB, the X-005US carries 128GB.

Unified memory means the CPU and GPU read the same pool, so model weights and working data stay in one place instead of being copied across a bus. That is the argument for this class of machine, and it is why the memory number matters more here than clock speed.

Storage also differs: the X-006US includes a 1TB SSD, while the X-005US comes with 4TB. The system has one internal M.2 slot, so there is no second slot for adding another internal SSD.

Compact enough for a desk you already use

Adding a computer to a desk full of monitors, drives, and networking gear is a space problem before it is a money problem. MSI keeps this one at 5.98 inches wide, 5.79 inches deep, and 2.09 inches tall.

MSI’s AI Pulse cooling system combines a vapor chamber with dual turbo fans. NVIDIA lists a 140W TDP for the desktop chip, and MSI supplies a 240W power adapter.

If you already run a workstation and want local AI beside it, this fits without rearranging the room.

Ports and displays

Moving model files and datasets is the everyday chore. MSI gives you four USB 3.2 Gen 2×2 Type-C ports at 20Gbps each, 10G LAN, Wi-Fi 7, and Bluetooth 5.4. The wired connection is the one that matters when datasets live on a NAS.

HDMI output runs 4K at 120Hz or 8K at 60Hz, and MSI supports up to four displays. Windows 11 Home ships, with Pro as an option. The processor is Arm, so your toolchain has to support it.

Which one to buy

At $4,699, the X-006US offers 64GB of unified memory and a 1TB SSD. It is the less expensive option for workloads that fit comfortably within that memory capacity.

The $7,999 X-005US doubles memory to 128GB and increases storage to 4TB without changing the CPU or GPU. Its appeal is the additional capacity for larger models and more demanding local AI workflows, not a faster processor.

For buyers who specifically need a compact local AI machine, that capacity is the main distinction. For everyday browsing and office work, neither configuration is an easy purchase to justify.
