Yesterday, NVIDIA announced the RTX SPARK super chip for Windows on Arm devices. The CPU part of the chip is customized by NVIDIA and MediaTek based on the Arm architecture. The first products provided by NVIDIA will include the N1 and N1X series, of which N1 is positioned as a mainstream chip, while N1X provides up to 20 cores and is positioned as a high-end flagship chip. Devices equipped with RTX SPARK super chips will be launched in the fall.
Early benchmark data leaks:
The benchmark website GeekBench has data submitted on March 29, 2026. The test data shows that the N1X has a single-core performance score of 3096 points and a multi-core score of 18837 points. This test result is equivalent to Apple’s flagship chip M3 MAX released in October 2023, which scored 3124 single-core and 18920 multi-core.
However, the M3 MAX uses 14 cores instead of 20 cores, so judging from the benchmark data alone, Apple's chip architecture is still capable even though it has been released for 3 years. However, after all, Apple has been deeply involved in the field of Arm chips for many years, and Nvidia is now in its infancy. With subsequent chip iterations, N series chips may eventually achieve the same performance as M series chips of the same generation.
As for why GB10 is displayed in the benchmark database, it is because NVIDIA uses the GB10 chip in the desktop AI workstation DGX SPARK. Huang Renxun said that N1X is an improved version developed by NVIDIA based on the GB10 chip, so the graphics performance of N1X should be similar to GB10. The graphics performance of GB10 is equivalent to the RTX 5070 level.
Of course, the test data does not represent the latest situation:
The earliest test data for an N1X or similar engineering sample found in the benchmark database was published in June 2025.These engineering samples typically do not include software and firmware optimizations for the final product, as Nvidia and OEM partners optimize, the test data of the N1X chip may be better, but unfortunately there are only test data based on Linux systems, and no test data equipped with Windows 11.
Considering the performance issues of Windows 11, the final Windows on Arm experience on N1X still needs to wait until the final product is released for real evaluation. Perhaps Microsoft is also stepping up its efforts to optimize the Windows 11 system to avoid overturning when the final product is launched.
