MSI EdgeMesa N RTX Spark Mini PC Lists at $7,999; Gigabyte Aero Unpriced

MSI's US store listed the 128 GB EdgeMesa N AI+, one of the first RTX Spark mini PCs, built on NVIDIA's chip, at $7,999.00 on Nov. 11, 2026, and showed it out of stock.

Two RTX Spark mini desktops surfaced within a day. Gigabyte launched its AI TOP Aero on Nov. 10, Notebookcheck reported, without a price. Notebookcheck then reported on Nov. 11 that MSI's EdgeMesa N was on sale in the US, ahead of Gigabyte's machine, from $4,699 with 64 GB of memory. NVIDIA had said on Oct. 7 that compact RTX Spark desktops would go on sale in November, so these are the first of that wave. No lab has published a language-model measurement of either desktop yet, so this file sets out what the makers state, what reviewers measured on other RTX Spark and GB10 machines, and what remains open.

What the RTX Spark Mini PC Is

RTX Spark is NVIDIA's Windows PC superchip. It pairs a 20-core Arm CPU with a Blackwell RTX GPU through one pool of unified memory. It was announced on May 31, 2026, at GTC Taipei, and has shipped in laptops since October. Our RTX Spark laptop review and the earlier laptop product file cover that side.

MSI's store page lists the EdgeMesa N X-005US with a 20-core Arm CPU (10 Cortex-X925 and 10 Cortex-A725 cores at up to 3.25 GHz, per MSI; NVIDIA's own page gives the core count but not the core types or clocks), a 6,144-core Blackwell RTX GPU, 128 GB of LPDDR5x unified memory at 273 GB/s, a 4 TB Gen5 NVMe drive and Windows 11 Pro. The box measures 5.98 by 5.79 by 2.17 inches, weighs about 5.5 lb and runs from a 240 W power adapter. MSI gives a three-year limited warranty. MSI's datasheet lists four 20 Gbps USB-C ports, one HDMI 2.1b output, one 10 Gb Ethernet port and Wi-Fi 7. The store's spec table says HDMI 2.1a, so MSI's own pages disagree on that point.

According to Notebookcheck, the 64 GB model costs $4,699 with a 1 TB PCIe Gen 5 drive. The case is 1.3 litres of aluminium, cooled by a vapour chamber and two fans rated for up to 140 W. The memory is soldered, and there is a single M.2 2242 slot for storage. The $4,699 figure is Notebookcheck's. MSI's page for that model could not be read, so Voltgrid has not seen the price on MSI's store.

Gigabyte's AI TOP Aero uses the same top RTX Spark chip, with 20 CPU cores and 6,144 CUDA cores, in a case of roughly 1 litre, according to Notebookcheck. It has up to 128 GB of LPDDR5X, up to 4 TB of PCIe 5.0 storage, USB-C, 10 GbE and Wi-Fi 7. Gigabyte's own newsroom and product pages could not be read, so every Aero specification here is as Notebookcheck reported it. Gigabyte has given no memory bandwidth and no price.

What's New in the EdgeMesa N and AI TOP Aero

The chip is not new; the shape is. Until now, a buyer who wanted this much unified memory on a desk had two routes. One was a DGX Spark or a partner GB10 box running NVIDIA's Linux-based DGX OS. The other was an RTX Spark laptop running Windows. These desktops put the RTX Spark chip in a box the size of a DGX Spark, with Windows 11 Pro. RTX Spark and GB10 are separate NVIDIA products.

Memory bandwidth sets how fast a model writes once it fits. MSI lists 273 GB/s for the EdgeMesa N, the same figure NVIDIA gives for both the 64 GB and 128 GB DGX Spark. ServeTheHome, writing about RTX Spark laptops, reported a higher ceiling of up to 300 GB/s from LPDDR5X-9400 on a 256-bit bus. NVIDIA's own RTX Spark page gives no bandwidth figure, so MSI's 273 GB/s is the only maker-stated number for a desktop, and MSI does not say why it is lower.

What MSI's datasheet does not list matters too. DGX Spark carries a ConnectX-7 network card at 200 Gbps, which lets two to four units pool memory for larger models. The EdgeMesa N's listed ports stop at 10 Gb Ethernet, so a 200 Gbps link between two boxes is not on offer. Gigabyte instead points to NVIDIA's Personal AI Router (PAIR), which Notebookcheck says spreads inference jobs across devices on a local network. Gigabyte also names LM Studio, Ollama, NVIDIA's Nemotron models and CUDA as supported.

MSI and NVIDIA both say the platform delivers up to 1 petaflop of FP4 AI performance, a vendor claim. Neither MSI's page nor NVIDIA's RTX Spark page says whether that figure is sparse or dense; NVIDIA labels the similar DGX Spark figure as theoretical, using sparsity.

What a Local AI Mini PC Should Solve

The target buyer wants a model in the 70B to 120B class held in memory on a Windows desk, without a cloud bill and without a laptop's thermal limits. NVIDIA rates RTX Spark for models of up to 120 billion parameters with a 1-million-token context, a vendor claim. A desktop also sidesteps the laptop throttling question. StorageReview measured the N1X CPU at up to 98 C in sustained loads on the Dell XPS 16 and HP OmniBook Ultra 16 laptops.

The closest measured reference is a different machine. StorageReview ran Qwen3.6-35B-A3B, a mixture-of-experts model, in a Codex CLI coding-agent task at a 64K context on HP's 128 GB OmniBook Ultra 16 laptop. It generated 89.5 tokens per second on Windows and passed three of three runs; the quantization was not stated in the figures cited here. On a GB10 desktop, Tom's Hardware measured the DGX Spark at about 20 tokens per second decoding the dense Qwen 3.8 27B with multi-token prediction, with quantization and software not stated in the figures cited here. The two results use different models, tools and operating systems, so they do not compare with each other. Neither was taken on an EdgeMesa N or an AI TOP Aero, and neither should be read as one.

Price is where the desktops have to argue their case. At 128 GB and 273 GB/s, MSI lists $7,999, against the $6,950 DGX Spark listing on NVIDIA's enterprise marketplace, a price read on Oct. 31 with stock unverified. At 64 GB, Notebookcheck reports $4,699 for MSI, against the $4,999 at which 64 GB DGX Spark partner systems started on Oct. 23. Notebookcheck put Gigabyte's GB10-based AI TOP Atom at $4,999 with 64 GB and a 2 TB drive. Below all of them sit AMD Strix Halo boxes at lower bandwidth. The Framework Desktop with 128 GB listed at $3,449 at 256 GB/s, though it was out of stock on Nov. 4, and GMKtec's EVO-X2 with 128 GB was $3,499.99 on Nov. 10.

Why Memory Size and Speed Decide Local AI

A language model has to sit in memory before it can run, so capacity decides which models fit. MSI's EdgeMesa N AI+ carries 128 GB of unified memory that the CPU and GPU share, and NVIDIA rates the RTX Spark platform for models of up to 120 billion parameters, a vendor claim.

Speed is a separate limit. To write each new word, the chip reads the model's weights from memory, so memory bandwidth, the rate at which data moves, usually caps how fast text appears. MSI lists 273 GB/s for the EdgeMesa N. That is a ceiling, not a measurement: no one has published tokens per second for these desktops, and a fixed GPU share of memory can shrink what actually fits. A machine can hold a large model and still write slowly.

What Is Not Confirmed Yet

No independent outlet or lab has published a tokens-per-second figure for any RTX Spark desktop. Until one does, decode speed on these boxes is unknown. The shared 273 GB/s figure is not a substitute.

The memory split is the biggest open question for model size. On RTX Spark laptops, StorageReview found that Windows fixes the GPU's share of memory in advance rather than sharing it on demand. Its 64 GB Dell XPS 16, split 32/32, left 30.5 GB usable by the GPU. Whether the desktops ship with a larger GPU share on 128 GB, or let users change it, neither maker has said.

Several other points are open. Gigabyte's AI TOP Aero has no price, no stated bandwidth and no US retail listing. Its specifications rest on one outlet's report of a release Voltgrid could not read. MSI's $4,699 64 GB price rests on Notebookcheck. MSI has given no restock date for the 128 GB model, and non-US prices are unknown. Notebookcheck notes that early RTX Spark reviews found some games failing to launch or crashing. Nothing yet shows whether either desktop holds 140 W under a long inference run, or how loud it gets. MSI lists fan noise of 28 at idle and 32 at full load, without a unit.

Neither maker has announced a review date or an embargo. Gigabyte has not said when the AI TOP Aero will get a US price, and MSI has not said when the 128 GB EdgeMesa N returns to stock. Reviews of the RTX Spark laptops appeared around their Oct. 16 on-sale date, but no outlet has said it has either desktop in hand. When the first measured local-model runs land, with the model, quantization and tool stated, this product file becomes the base for a full review of the machine they cover.
