NVIDIA Unveils RTX Spark Platform With 1 Petaflop AI Performance and Up to 128GB Memory

NVIDIA has unveiled RTX Spark, a new computing platform developed in collaboration with Microsoft that aims to bring AI-powered experiences directly to Windows PCs. Announced at GTC Taipei 2026, the platform combines NVIDIA's Blackwell graphics architecture, Grace CPU technology, and a Windows-native AI framework designed for running personal AI agents locally.

The company says RTX Spark-powered laptops and compact desktops will be available later this year from manufacturers including ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI. Acer and GIGABYTE are expected to launch devices based on the platform at a later stage.

Built Around Local AI Agents

AI agents are at the center of NVIDIA's vision for RTX Spark.

The company is working with Microsoft to create a native Windows environment where AI agents can run directly on users' devices rather than depending entirely on cloud services. To support this, RTX Spark introduces new Windows security features alongside NVIDIA OpenShell, a runtime designed to help users manage what AI agents can access and perform on their systems.

According to NVIDIA, these agents could carry out tasks across applications, search local files, generate content, and automate workflows while keeping sensitive information on-device when required.

Up to 1 Petaflop of AI Performance

At the heart of RTX Spark is a custom chip that combines an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores, paired with a 20-core NVIDIA Grace CPU.

The platform supports up to 128GB of unified memory and delivers up to one petaflop of AI computing performance, according to NVIDIA. The company says RTX Spark systems will be capable of running large language models with up to 120 billion parameters and context windows reaching one million tokens.

MediaTek collaborated with NVIDIA on the custom CPU design, with a focus on power efficiency and connectivity.

Gaming and Creative Workloads Remain a Key Focus

While AI is the headline feature, RTX Spark also includes NVIDIA technologies such as CUDA, RTX, DLSS, Reflex, TensorRT, and OptiX.

NVIDIA says the platform can handle 90GB-plus 3D scenes, edit 12K video, generate 4K AI videos, and run modern AAA games at 1440p resolution with frame rates exceeding 100fps when supported by RTX technologies.

The company also revealed support from more than 100 software developers and partners, including Adobe, Blackmagic Design, Blender, CapCut, ComfyUI, OTOY, Xbox, Riot Games, NetEase, Remedy Entertainment, and KRAFTON.

Adobe Apps Are Being Optimized for RTX Spark

Adobe is partnering with NVIDIA to redesign parts of Photoshop and Premiere Pro for RTX Spark hardware.

The companies say future versions of these applications will take advantage of the platform's unified memory architecture, Blackwell GPU, and TensorRT acceleration. Adobe expects improvements in AI-powered editing, compositing, rendering, and video production workflows.

Adobe says updates to its creative applications will begin rolling out alongside the launch of RTX Spark devices.

Availability

RTX Spark-powered laptops and compact desktops are expected to launch in fall 2026 through major PC manufacturers including ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI.
