"New PC Era": NVIDIA Unveils RTX Spark Platform Based on Grace Blackwell Superchip with RTX 5070-Level Graphics

At GTC Taipei, NVIDIA, in collaboration with Microsoft, unveiled RTX Spark — a new Windows platform based on the Grace Blackwell superchip. The product is an ARM chipset that combines a Blackwell graphics core with 6144 CUDA cores and 5th-generation Tensor Cores with FP4 support, as well as a 20-core Grace processor, developed in partnership with MediaTek. The components are connected by an NVLink-C2C bus with a bandwidth of 600 GB/s, which is five times faster than the PCIe Gen5 interface.

Top configurations of the platform will feature up to 128 GB of unified LPDDR5X memory, with a minimum of 16 GB. According to NVIDIA, the chip's graphics power is close to that of the mobile GeForce RTX 5070 Laptop. The platform is capable of delivering over 100 FPS at 1440p resolution in modern AAA games, including Indiana Jones and the Great Circle, with ray tracing and DLSS.

For AI and demanding professional software, RTX Spark delivers up to 1 petaFLOP of AI performance in FP4 computations. This will allow local execution of language models with 120 billion parameters and a context window of up to 1 million tokens, processing 3D scenes up to 90 GB, and editing 12K video.

Since RTX Spark is built on the ARM architecture, traditional x86 applications will run via the Microsoft Prism emulator. However, many developers are already preparing native versions of their products. NVIDIA has confirmed support for Blender, DaVinci Resolve, Cinema 4D, CapCut, and Cubase, while Adobe is adapting Photoshop and Premiere Pro for the new platform.

The first devices to feature RTX Spark will be premium laptops such as ASUS ProArt P14/P16, Dell XPS 16, HP OmniBook X14, Lenovo Yoga Pro 9N, Microsoft Surface, and MSI Prestige N16 Flip. In total, NVIDIA's partners are developing over 30 laptop models and 10 compact PCs.

NVIDIA promises to reveal device pricing, independent test results, and detailed benchmarks closer to the start of sales, scheduled for this autumn. RTX Spark will be a long-term family of chips designed for various price segments.
