Nvidia said on 3 September that the first RTX Spark Windows PCs will start shipping in October. The announcement came out of IFA 2026 in Berlin, where Lenovo showed the Yoga Pro 9n and the Yoga 9n 2-in-1, and Acer showed a compact RTX Spark desktop concept. Nvidia says these designs join six PC makers already lined up to ship in October.
RTX Spark is Nvidia’s own processor for Windows PCs. It puts an Arm-based Grace CPU and a Blackwell RTX GPU on a single package. Nvidia’s headline pitch is a 1 petaflop RTX Blackwell GPU, up to 128GB of unified memory and a 20-core Grace CPU. That sentence is the part worth slowing down on, because it describes one of two configurations.
RTX Spark comes in two configurations, and the gap matters
Windows Central, which published Nvidia’s configuration details the same day, reports two different configurations of the N1X. Memory and storage are then left to each PC maker to choose.
- Higher-end configuration — 6,144-core Blackwell RTX GPU, 20-core Grace CPU, 24GB to 128GB unified memory. Goes into both laptops and compact desktops.
- Lower configuration — 5,120-core Blackwell RTX GPU, 18-core Grace CPU, 24GB or 32GB unified memory. Laptops only.
Note what the second line does. The cheaper configuration tops out at 32GB. Even the expensive one can ship in a 24GB configuration if the manufacturer decides to build it that way. Nvidia is selling RTX Spark on running large AI models on your own machine instead of in the cloud. Memory is the spec that decides how large a model actually fits. The number in the marketing line, 128GB, is a ceiling reachable by only the larger of the two configurations.
None of that makes these bad machines. It does mean the shelf label will read RTX Spark on two quite different products. The buyer has to read the memory figure rather than the badge.
What else Nvidia announced
- Windows Agent Framework support — RTX Spark is rated to run agents of up to 120 billion parameters locally, per Windows Central.
- Gaming — Windows Central reports an expectation of about 100fps in many games at 1440p with ray tracing and DLSS. Nvidia says Electronic Arts, Embark and Ubisoft are among the studios bringing titles to the platform.
- Nvidia PAIR — a Personal AI Router that spreads AI work across multiple Nvidia PCs on your home network.
- Faster local inference — Nvidia claims gains of up to 1.9x from new llama.cpp and vLLM work, available through LM Studio and Ollama.
The Arm question
Grace is an Arm design, so RTX Spark machines are Windows-on-Arm PCs. Nvidia says many mainstream game developers have committed to native support, so there are no compatibility problems on Arm. That is a fair claim for games shipping with the platform. It does not settle the wider question of older Windows software. Arm builds of Windows still throw up app-specific problems — we covered one earlier this month, when Teams and the new Outlook stopped launching on ARM-based Windows 11 PCs. If you depend on a niche or elderly Windows application, check it before you buy.
Pricing and availability
Nvidia’s announcement carries no prices, and pricing is each manufacturer’s call. It does not cover India pricing or availability either. Shipping is stated as October 2026, with the specific launch dates resting with each PC maker.
