Overview

GeForce GT 620M is an NVIDIA GPU entry in the GeForce 600 Series family. It is listed with Fermi 2.0 architecture and GF117 silicon.

Key reference data: 96 CUDA cores/shaders, 1 GB DDR3 memory, 64-bit memory bus, 15 W board power class.

Laptop implementations can vary by OEM power limit, cooling, memory configuration, and driver package.

Why It Mattered

GeForce GT 620M matters as a mobile GeForce 600 Series implementation from the Fermi 2.0 generation around 2012. Laptop GPU names often hide large differences in power limits, cooling, memory, and OEM firmware, so tracking the exact variant explains why similarly named systems can perform differently.

Collector Notes

For archival use, record the exact laptop or module model, OEM subsystem ID, TGP or power profile, memory size and type, VBIOS, cooling design, display mux or Optimus behavior, and driver package used by the system vendor.

Used-Market Caution

Do not buy a laptop by GPU name alone. Confirm the exact laptop model, TGP, memory configuration, charger, cooling condition, display mux, BIOS support, driver branch, battery health, and whether the GPU is soldered or part of a replaceable module.
