Leaked Benchmarks Reveal NVIDIA’s Prototype N1x SoC Matches RTX 5070 in CUDA Cores

Leaked Geekbench OpenCL results show the 120 W N1x prototype features 20 ARM cores, 48 Compute Units, 1.048 GHz GPU clocks, shared LPDDR5X memory under pre-production constraints

Nvidia CEO Jensen Huang holds a Blackwell GeForce RTX 50 Series GPU (L) and a RTX 5000 laptop as he delivers a keynote address at the Consumer Electronics Show (CES) in Las Vegas, Nevada on January 6, 2025.

Overview

  • Engineering-sample N1x recorded a 46,361 score in Geekbench OpenCL, outpacing current integrated GPUs from Intel, AMD and Qualcomm in early tests.
  • The N1x’s 48 Compute Units deliver 6,144 CUDA cores—identical to the desktop RTX 5070—but its 1.048 GHz cap and 120 W envelope suggest lower raw throughput.
  • The chip forgoes dedicated GDDR7 VRAM in favor of onboard LPDDR5X, trading memory bandwidth for integration and power efficiency.
  • On the CPU side, the SoC combines two 10-core Arm ‘Grace’ clusters for 20 cores, mirroring NVIDIA’s GB10 superchip design in a consumer-oriented package.
  • NVIDIA and MediaTek are targeting an early 2026 unveiling, with driver refinements and power-frequency tuning expected to unlock further performance.
