HARDWARE NEWS manhkbrady - about 1 hour ago

Ahead of Computex 2026, Nvidia teased the arrival of “a new era of PC,” and the company has now officially unveiled RTX Spark, a new Windows-on-Arm platform that marks Nvidia’s expansion beyond graphics cards and into full PC systems.

At the heart of the platform is the RTX Spark Superchip, which combines a 20-core Grace CPU with a Blackwell-based GPU featuring up to 6,144 CUDA cores and up to 128GB of unified memory. Notably, that GPU core count matches Nvidia’s desktop GeForce RTX 5070, although the Spark platform operates within a much more power-efficient integrated design. The CPU and GPU are linked using Nvidia’s high-bandwidth NVLink-C2C interconnect.

With RTX Spark, Nvidia is delivering what it calls the “full Nvidia stack,” including support for technologies such as CUDA, RTX ray tracing, DLSS, TensorRT, OptiX, Reflex, FP4 acceleration, and G-SYNC. This makes the platform attractive not only for gamers but also for content creators, AI developers, and workstation users.

Gaming is a major focus for RTX Spark. Nvidia demonstrated the platform running what appeared to be Forza Horizon 6 at 1440p with ray tracing and DLSS enabled, reportedly achieving around 100 FPS. The company also showcased Indiana Jones and the Great Circle, highlighting the platform’s gaming capabilities and signaling a serious push to improve Windows-on-Arm’s reputation among PC gamers.

Nvidia's initial RTX Spark rollout targets premium 14-inch and 16-inch laptops from major manufacturers including ASUS, Dell, HP, Lenovo, MSI, and Microsoft, positioning them as high-end MacBook competitors with powerful graphics and unified memory. Workstation-class desktops are also planned with partners such as Acer, ASUS, Dell, Gigabyte, HP, Lenovo, and MSI. Supporting up to 128GB of unified memory, these machines are particularly appealing for AI workloads and professional content creation, providing a significant advantage over traditional discrete GPU setups.

Nvidia also revealed that Adobe is developing native versions of applications such as Photoshop and Premiere Pro specifically optimized for the Spark platform, with additional Arm-native creative software expected to follow.

RTX Spark laptops and desktops are scheduled to launch this fall. Nvidia says early models will target the premium market, while more affordable configurations are planned for the future. One limitation is that RTX Spark systems cannot be paired with discrete GPUs, keeping the platform focused on compact, highly integrated designs similar to Apple Silicon-based Macs.
