NVIDIA RTX Spark AI superchip for Windows PCs

After months of intense rumours, NVIDIA has finally and officially unveiled RTX Spark, a new Arm-based “superchip” designed to power a new generation of Windows PCs focused on local AI workloads, content creation and gaming.

Announced ahead of Computex 2026 in Taipei, RTX Spark marks one of NVIDIA’s biggest moves yet beyond discrete graphics cards, with the company positioning the chip as the foundation for what it calls the next era of personal AI computing. Developed in partnership with Microsoft and MediaTek, RTX Spark combines NVIDIA’s Blackwell RTX GPU architecture, Grace CPU technology and AI software stack into a single platform for laptops and standard and compact desktop PCs.

According to NVIDIA, RTX Spark delivers up to one petaflop of AI performance and supports up to 128GB of unified memory. It also claims the platform is capable of running large AI models with up to 120 billion parameters locally, while also handling demanding creative workloads such as editing 12K video, generating 4K AI video content and rendering massive 3D scenes exceeding 90GB in size. Gaming performance is expected to be really good too, with NVIDIA promising 1440p gameplay at over 100fps in modern AAA titles like Pragmata and the recently launched 007 First Light.

AI agents on Windows

The bigger story, however, is NVIDIA’s push towards agentic AI on Windows. It says RTX Spark-powered PCs are being built specifically to run AI agents locally, allowing them to perform tasks across applications, search files, generate content and automate workflows while keeping sensitive data on-device. NVIDIA is also working with Microsoft on new Windows security and isolation frameworks, alongside a new OpenShell runtime environment designed to give users more control over how AI agents access applications and personal information.

At his keynote earlier, NVIDIA CEO and co-founder Jensen Huang described the launch as a “redefinition of the personal computer”, saying that users will increasingly interact with AI-powered assistants instead of manually launching applications and navigating workflows themselves.

What are the RTX Spark laptops available?

Hardware partners are already lining up behind the platform. NVIDIA says RTX Spark-powered laptops and compact desktops will begin arriving this autumn (or Q3) from manufacturers including ASUS, Dell, HP, Lenovo, Microsoft and MSI, with additional systems from Acer and Gigabyte expected to follow later.

What does this means for Intel, AMD, Qualcomm and Apple?

For NVIDIA, RTX Spark also represents something else entirely: a direct entry into the Windows PC processor market, putting it on a collision course with Intel and AMD in the PC space.

It’ll be interesting to see how the chip performs against the latest x86 offerings from both companies, especially since gaming remains a key part of NVIDIA’s pitch. But the more fascinating comparison might be against other Arm-based processors. Qualcomm has spent the past two years trying to convince Windows users that Arm PCs are ready for the mainstream, while Apple’s M-series chips have become the yardstick that every Arm processor inevitably gets measured against.

RTX Spark arrives with NVIDIA’s considerable AI expertise behind it, but whether that’s enough to carve out a place in an increasingly crowded Arm PC market is a question that won’t be answered until the first systems land later this year in our hands.
