NVIDIA RTX Spark N1X
NVIDIA's RTX Spark N1X is an Arm-based superchip for Windows laptops and compact desktops that pairs a 20-core Grace CPU (10 performance and 10 efficiency cores) with a 6,144-core Blackwell RTX GPU and up to 128GB of unified LPDDR5X memory. NVIDIA lists its TDP as 45-80W in laptops and 140W for a desktop configuration. NVIDIA also lists a second, 18-core N1X with a 5,120-core GPU under the same name.
Pros
- 20 Arm cores: 10 performance (Cortex-X925) and 10 efficiency (Cortex-A725)
- Integrated Blackwell RTX GPU with 6,144 CUDA cores, 4th-generation ray tracing cores and 5th-generation Tensor cores
- Up to 128GB of unified memory shared by the CPU and GPU, with 300GB/s of bandwidth
- NVIDIA rates the chip at up to 1 petaflop of FP4 AI compute
Cons
- No benchmark results from retail laptops are published yet; laptops begin shipping on 16 October 2026
- Runs Windows 11 on Arm, so x86 apps depend on emulation and can run slower than native Arm apps
- NVIDIA's public spec sheet does not list clock speeds or cache sizes for the chip
Awaiting benchmarks
No Inno Score yet: single-core and multi-core still need a published benchmark result. The sub-scores below come from the spec sheet.
