Nvidia RTX Spark: Everything We Know About Specs, Benchmarks, Partners, and Pricing (Fall 2026)

Nvidia's long-rumored entry into the Windows on Arm PC market is finally taking shape. The RTX Spark platform, featuring custom Arm-based superchips developed with MediaTek, promises to bring desktop-class GPU performance and on-device AI capabilities to a new generation of slim laptops and compact desktops.

This article compiles every verified detail from the first developer preview drivers, leaked benchmarks, official partner announcements, and analyst pricing estimates, all backed by cited sources.

Developer Preview Drivers (Version 616.00)

Nvidia released its first RTX Spark developer preview driver, version 616.00, on July 18, 2026, alongside the CUDA Toolkit 13.4 Developer Preview . This is the first native Windows on Arm GPU driver package for the RTX Spark platform .

Target hardware: The initial 616.00 driver is aimed specifically at Microsoft's Surface RTX Dev Box, a developer reference device, not at retail consumer laptops .

CUDA Toolkit 13.4: The preview adds a native CUDA development package for Windows Arm64, letting developers compile CUDA applications directly on Arm systems . The release notes from Nvidia confirm support for compiler and build-system enablement for Windows on Arm .

Known issue: The release notes flag reduced CUDA transfer performance when using pageable memory, with a workaround recommending page-locked host memory .

Significance: The driver's appearance confirms Nvidia is actively preparing the software stack ahead of the fall 2026 consumer launch .

N1X Cinebench 2026 Benchmark Leak

On July 18–19, 2026, a Cinebench 2026 result from a pre-release Microsoft Surface Laptop Ultra (engineering sample) was shared by TechPowerUp forums user Fouquin .

N1X specs in the leak: A 20-core Grace-architecture CPU (two 10-core clusters) paired with 48 streaming multiprocessors (6,144 CUDA cores), matching the desktop RTX 5070 in GPU core count . The chip features up to 128 GB of unified LPDDR5X memory .

Cinebench 2026 scores: 5,771 multi-core, 540 single-core, tested using Cinebench's 10-minute sustained throttling mode .

M3 Max comparison: The N1X's single-core performance is described as "on par" with the 14-core Apple M3 Max from 2023 . Earlier Geekbench 6 leaks from May–June 2026 also showed the N1X scoring 3,096 single-core / 18,837 multi-core, roughly matching the M3 Max's 3,124 / 18,920 .

Caveat: This is an engineering sample result; final retail performance may differ . Apple's newer M4 and M5 Max chips are significantly faster, and the N1X uses a 20-core design (vs. M3 Max's 14 cores) to achieve comparable scores, highlighting Apple's architectural efficiency .

GPU performance: In OpenCL tests, the N1X integrated GPU scored 46,361 points, outperforming the Apple M3 Max (approx. 37,500) and all current integrated GPUs, though the early sample ran at a conservative 1.05 GHz clock speed .

Partner Lineup — Fall 2026 Launch

Nvidia unveiled RTX Spark at Computex 2026 on May 31, 2026 . Eight confirmed Windows laptops will launch this fall from six partners, with more than 30 total designs expected .

Partner	Confirmed Models
Microsoft	Surface Laptop Ultra (flagship N1X model, 15-inch mini LED display, 2,000-nit peak brightness)
ASUS	ProArt P16 and ProArt P14 (creator-focused)
Dell	XPS 16 Creator Edition
HP	HP OmniBook X 14 and OmniBook Ultra 16
Lenovo	Yoga Pro 9n
MSI	Prestige N16 Flip AI+ (2-in-1 convertible)

Acer and Gigabyte have also confirmed they will ship RTX Spark devices in a later wave . Nvidia has stated these laptops will feature tandem OLED G-Sync displays and "all-day" battery life .

Expected Pricing

Nvidia has not published official MSRPs, but analysts (including Morgan Stanley, who surveyed vendors at Computex 2026) have provided estimates .

N1 (base) models: Expected to start around $1,799–$1,800. The N1 chip uses a 12-core Grace CPU and a GeForce RTX 5050-class GPU with up to 64 GB of unified memory .

N1X (flagship) models: Expected to start at or above $2,899. The N1X features a 20-core Grace CPU, a Blackwell GPU with 6,144 CUDA cores (RTX 5070-class), and up to 128 GB of unified LPDDR5X memory .

Source of estimates: Morgan Stanley analyst reports based on direct interviews with PC manufacturers at Computex 2026, and multiple tech outlets (PC Magazine, WCCFTech, VideoCardz, Notebookcheck) .

Uncertainty: These are analyst projections, not official Nvidia pricing. Actual retail prices will vary by OEM configuration, memory, and storage options . PCWorld's sources suggested a slightly wider range of $2,500–$2,900 for N1X and $2,000–$2,500 for N1 configurations .

The Bottom Line

The RTX Spark platform is in active developer enablement (driver 616.00, CUDA 13.4 preview). The N1X chip benchmarks at M3 Max-class CPU performance in Cinebench 2026, with an RTX 5070-class integrated GPU that leads all current integrated graphics. Six major OEMs (ASUS, Dell, HP, Lenovo, Microsoft, MSI) have confirmed fall 2026 laptops, with eight models at launch and 30+ in development. Analyst-estimated pricing is ~$1,799+ for N1 models and ~$2,899+ for N1X models, positioning them against premium machines like the MacBook Pro, though official MSRPs remain unannounced.
