Overview

Switch GPU 20nm is an NVIDIA GPU entry in the Console GPU (Nintendo) family. It is listed with Maxwell 2.0 architecture and GM20B silicon.

Key reference data: 256 CUDA cores/shaders, 4 GB DDR4 memory, 64-bit memory bus, 15 W board power class.

Board-partner cards can vary in cooler, PCB, display outputs, clocks, BIOS behavior, and power connector layout.

Why It Mattered

Switch GPU 20nm matters because console GPUs are fixed-platform designs, not retail cards. The useful history is tied to the console generation, board revision, thermal design, and software target, so this entry keeps those platform-specific details separate from desktop GPU naming.

Collector Notes

For archival use, record the console model, motherboard revision, cooling assembly, firmware version, memory configuration, display output, power supply, storage, and repair history rather than treating the GPU as a loose PC card.

Used-Market Caution

Before buying used, check the whole console or donor board for video output, overheating, prior reflow or reball work, power-supply faults, storage condition, and whether the firmware and accessories match the intended repair or collection use.

Known Issues

Known issues pending source review.
