NVIDIA RTX Spark Windows PCs Launch With 128GB RAM and 1 Petaflop

NVIDIA and Microsoft have launched RTX Spark, a new generation of Windows PCs designed for gaming, content creation, and running AI models locally.

The new devices combine an NVIDIA Blackwell RTX GPU and Grace CPU in a single superchip, offering up to 128GB of unified memory and 1 petaflop of FP4 AI performance. Prices start at $2,599, with laptops from six major manufacturers.

RTX Spark brings powerful local AI to Windows

RTX Spark allows users to run large language models and personal AI agents directly on their computers, reducing their dependence on cloud services.

The platform supports AI agents including GitHub Copilot, Hermes, OpenClaw, Perplexity, Pi, and WorkBuddy, with simplified installation and configuration.

NVIDIA has also optimized its Nemotron 3.5 Bolt 74B-A9B model for tool calling and multistep AI tasks. The model contains 74 billion parameters and can support complex agent workflows.

For security, NVIDIA OpenShell and Microsoft Execution Containers provide controls for managing agent permissions and access to system resources.

Another feature, NVIDIA PAIR, lets RTX Spark computers share AI inference capabilities with other Windows, Linux, and macOS devices over a local network.

NVIDIA targets creators and developers

Beyond AI, RTX Spark supports demanding creative workloads, including 8K 4:2:2 video editing and rendering 3D scenes up to 90GB, even when running on battery power.

Adobe is introducing NVIDIA TensorRT acceleration for AI features in Photoshop, Premiere, and Substance 3D. Photoshop and Premiere receive native RTX Spark support through launch-day beta releases, while Substance support will follow later.

NVIDIA Broadcast 2.3 introduces improved noise removal and Studio Voice Mic Profiles. RTX Video also supports up to 4K super resolution and 4x frame generation in beta.

New ComfyUI nodes can increase AI-generated video from 15 FPS to 60 FPS and convert footage to HDR locally.

Developers get native CUDA support, Windows Subsystem for Linux compatibility, PyTorch-CUDA for Windows on Arm, and native Python and Conda tools. NVIDIA claims compatibility with 97% of the top 15,000 Python packages.

MediaTek collaborated with NVIDIA on the custom CPU design, focusing on power efficiency, performance, and connectivity.

RTX Spark supports DLSS 5 and ray tracing

NVIDIA is also positioning RTX Spark as a gaming platform, with support for DLSS 5, ray tracing, G-SYNC, Reflex, and other RTX technologies.

Supported launch titles include Cyberpunk 2077, Fortnite, Gears of War: E-Day, Marvel Rivals, World of Warcraft, and NBA 2K27.

NBA 2K27 uses DLSS 5 with 3D-Guided Neural Rendering to improve lighting and material details.

NVIDIA also says its latest AI model runs twice as fast and can increase DLSS 5 frame rates by up to 1.4x.

RTX Spark laptops start at $2,599

The first RTX Spark laptops are now available globally, starting at $2,599. The launch lineup includes the ASUS ProArt P14 and P16, Dell XPS 16, HP OmniBook Ultra and OmniBook X 14, Lenovo Yoga Pro 9n, Microsoft Surface Laptop Ultra, and MSI Prestige N16 Flip AI+ and Prestige N16.

Pricing and configurations vary by region, with availability through manufacturers’ websites and major retailers.

NVIDIA says the new laptops combine high-performance AI processing with slim designs and all-day battery life, bringing workstation-class capabilities to portable Windows PCs.
