GeForce GT 500M系列全部基于GF108核心，并且显存全部改用DDR3颗粒，其中以GeForce GT 555M规格最高，拥有144个流处理器，核心/流处理器频率590/1180MHz，显存位宽192-bit，等效频率3600MHz，带宽43.2GB/s，不再支持双卡SLI，其替代对象自然是GeForce GT 445M。从照片上看，该卡核心仍然需要加装散热保护盖。

GeForce GT 550M/540M/525M都是96个流处理器，核心频率分别为740/672/600MHz，依次降低，显存位宽也降至128-bit，等效频率均为1800MHz，带宽降至28.8GB/s。它们将分别取代GeForce GT 435M/425M/420M。也就是从这里开始，核心功耗和温度大大降低，不再需要加装散热保护盖了。
