NVIDIA RTX Spark "superchip" and DLSS 4.5 Ray Reconstruction announced

NVIDIA used Computex 2026 to formally announce the RTX Spark "superchip" designed for AI, creating and gaming along with DLSS 4.5 Ray Reconstruction.

While a lot of what they're talking about for the RTX Spark related to AI workflows, they do also say it will be a good chip for gaming - primarily designed for laptops to give good overall performance. It features an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink-C2C chip-to-chip interconnect to a high-performance, 20-core NVIDIA Grace CPU. This Arm-based CPU was made in partnership with MediaTek.

“The PC is being reinvented,” said Jensen Huang, founder and CEO of NVIDIA. “For forty years, you launched apps. Click. Type. With RTX Spark and Microsoft Windows, you ask — and the PC does the work. RTX Spark brings everything NVIDIA has built — CUDA, RTX, our AI platform — into a single superchip. Local agents. Frontier models. Creative workflows. RTX games. All on a laptop. This is the new PC. The personal AI computer.”

From the press release:

RTX Spark delivers the full NVIDIA AI and graphics technology stack to creators, AI developers and gamers.

Users can render ultralarge 90GB 3D scenes with OptiX and DLSS, edit 12K 4:2:2 video with the NVIDIA Blackwell decoder, run 120-billion-parameter large language models with 1 million tokens context, and play AAA games at 1440p resolution and over 100 frames per second with ray tracing, DLSS and Reflex.

In addition to support for existing technologies, RTX Spark will power new RTX capabilities, including DLSS 4.5 Ray Reconstruction featuring a second-generation transformer model — coming to Blender 5.3 and dozens of games — and RTX Video with 4x Frame Generation, coming to ComfyUI.

RTX technology boosts performance, enhances image quality and adds powerful AI features in over 1,000 games and applications. Over 100 Windows software providers such as Adobe, Blackmagic Design, Blender, CapCut, ComfyUI and OTOY, and game developers such as KRAFTON, NetEase, Remedy Entertainment, Riot Games and XBOX are embracing the new RTX Spark platform.

It will be thoroughly interesting to see how the RTX Spark will work under Linux, since they're really only talking about Windows right now since it will launch with a bunch of laptops from various vendors like ASUS, Dell, HP, Lenovo, Microsoft Surface and MSI "this fall" with Acer and GIGABYTE to follow later.

Hopefully it won't take too long to get support for it under various Linux distributions.

DLSS 4.5 Ray Reconstruction was their other major announcement, which has a 2nd generation transformer model to deliver superior image quality in ray-traced and path-traced games. It's set to arrive in August with several major improvements:

• Efficient Denoiser: The new model delivers 35% more compute capability, and processes 20% more parameters, while maintaining similar performance to the previous model.
• Enhanced Super Resolution: Building upon the advances from DLSS 4.5 Super Resolution, the model has deeper spatial awareness across every scene, and more intelligently uses game engine pixel sampling and motion data. The result is improved lighting accuracy, better temporal stability and clearer motion in ray-traced and path-traced content.
• Expanded Training Dataset: Trained on a larger dataset, the new model is even better at image reconstruction. This intelligence gives the model even better awareness to pick the most accurate engine data to reconstruct scenes closer to ground truth.
• Finer Developer Control: The new model provides developers with finer control for temporal accumulation, providing precise tuning of model response for even better image quality.
