Nvidia RTX Spark Arm chip surfaces in first Cinebench 2026 leak
Nvidia's long-awaited RTX Spark (formerly known as N1X) appears to have surfaced on Cinebench 2026. A screenshot shared online shows what is believed to be an engineering sample of the chip running Maxon's latest benchmark under Windows 11. The benchmark identifies the processor as JMVW0A-Generic-CPU, a designation previously associated with Nvidia's Windows-on-Arm platform.
Its specs tacitly confirm it is an RTX Spark, complete with a 20-core CPU. The engineering sample records 5,771 points in Cinebench 2026's multi-core benchmark and 540 points in the single-core test. The screenshot reveals configurable power limits of 80 W PL1 and 95 W PL2, closely matching Nvidia's previously disclosed RTX Spark power envelope.
While engineering sample benchmarks should always be interpreted with caution, the leaked score is respectable when compared against our Cinebench 2026 database. The N1X trades blows with AMD’s Ryzen AI Max+ 395 and Intel’s Core Ultra X9 388H. However, Qualcomm's Snapdragon X2 Elite XE2-94-100 and Apple M5 Max are noticeably faster in single and multi-core performance.
The test system is also identified as a Surface Laptop Ultra, one of the many devices expected to ship with RTX Spark. Nvidia has already confirmed the chip will power laptops, mini PCs, and compact AI workstations, much like AMD's Strix and Gorgon Halo offerings.
That said, the benchmark is unlikely to reflect the processor's final performance. Besides the clearly erroneous 1.01 GHz frequency readout, the generic CPU and GPU identifiers indicate that the platform is still using pre-release firmware. The final product has the potential to trade blows with Intel Panther Lake and maybe even AMD Medusa Point, but Qualcomm and Apple’s Arm-based offerings are difficult to surpass this generation.
