It's a tie. In the Production Modules group, where the Jetson Nano is filed, two modules have the most GPU CUDA cores: the Jetson AGX Thor T5000 and the IGX T5000. Each has 2,560 CUDA cores and 128 GB of LPDDR5X memory. developer... +1developer.nvidia.com ↗“Flagship Blackwell-generation SoM for physical AI/humanoid robotics; up to 2070 FP4 TFLOPS, 128GB LPDDR5X (273 GB/s)”nvidia.com ↗“2560-core Blackwell GPU, 14-core Neoverse-V3AE, 128GB LPDDR5X”

The two leaders are separate products. The IGX T5000 is an IGX Thor module (P/N 900-23834-0080-000) with optional functional safety. The Jetson T5000 is P/N 900-13834-0080-001. The two share the same form factor and pinout. nvidia.comnvidia.com ↗“a separate SKU from Jetson T5000 (P/N 900-13834-0080-001) but form-factor and pin-compatible with it”
I checked every Production Modules entry rated at 2,048 CUDA cores or more. Only these four turned up, so nothing in the group has more than 2,560.
