PCs with NVIDIA RTX Spark to Launch This Fall, Offering 1 Petaflop Local AI Processing

The first Windows laptops and desktop PCs equipped with NVIDIA’s new superchip, the “RTX Spark,” are expected to hit the market this fall. Major PC manufacturers, including Asus, Dell, HP, Lenovo, Microsoft, and MSI, have already announced plans to release devices built on this platform. While pricing and specific release dates have yet to be disclosed, it is likely that the initial models will be priced at the higher end of the market given their target audience and performance capabilities.

Overview of the Hardware

The RTX Spark platform is designed for “developers, creators, and power users” and integrates a 20-core Arm-based CPU with NVIDIA Blackwell RTX graphics featuring 6,144 CUDA cores. The chip delivers up to 1 petaflop of local AI processing power and supports up to 128GB of high-bandwidth unified memory. According to NVIDIA, this hardware allows users to locally run large language models (LLMs) with 120 billion parameters and play AAA games at 1440p resolution with 100fps performance.

Relationship with DGX Spark

The RTX Spark’s technical foundation is nearly identical to the “GB10 Grace Blackwell superchip” that powers NVIDIA’s DGX Spark mini-PC, released last year. However, there are two key differences. First, while the GB10 Grace Blackwell chip was initially compatible only with Linux, the RTX Spark fully supports Windows 11. Second, whereas the GB10 was limited to NVIDIA’s proprietary DGX Spark and select third-party products based on the same platform, the RTX Spark has been adopted by multiple major PC manufacturers, paving the way for a broader range of devices.

Currently, the desktop version of the DGX Spark mini AI workstation is priced at around $4,600. Prior to the official announcement, information about the chip was leaked under the code name “NVIDIA N1X (675).” The leak also hinted at the potential release of a more affordable, lower-performance variant, but NVIDIA has not announced any plans for such a model at this time.

Arm Architecture and Windows 11

Another notable aspect of RTX Spark is its use of Arm architecture. While Microsoft has been enhancing support for Arm in Windows 11, many Windows applications have yet to be natively compiled for Arm. When running x86 applications on Arm, the Windows Prism emulator handles the processing, which may impact performance.

Microsoft has stated that, in addition to improving Prism, it is actively collaborating with NVIDIA and third-party developers to port more applications to Arm-native compatibility.

Key Native Applications

Currently, several creative applications are already available in Arm-native versions, including Blender, DaVinci Resolve, Maxon Cinema4D, Maxon Redshift, Topaz Photo, CapCut, Cubase, Bitwig Studio, and Affinity by Canva. Adobe Photoshop and Adobe Premiere Pro are also natively supported. The ability to run these applications without relying on emulation significantly enhances the practicality of using Arm-based PCs for creative work.

Pricing and Market Impact

The price of RTX Spark PCs has not yet been announced, but given that the comparable DGX Spark costs around $4,600, the initial lineup is expected to fall into the high-price range. However, NVIDIA has emphasized that the platform will deliver “best-in-class power efficiency” along with discrete GPU-level graphics performance for gaming, graphics work, and AI processing. This positions RTX Spark PCs as a potential game-changer in the professional market, significantly elevating the status of Arm-based PCs.

The launch of RTX Spark-equipped PCs is expected to further solidify Arm’s presence within the Windows ecosystem. For developers looking to run large-scale AI models locally, or creators requiring high-performance AI acceleration, RTX Spark offers a compelling alternative to traditional x86-based PCs.
