GeForce 8400 GS Rev. 2 Game Requirement Analysis
GeForce 8400 GS Rev. 2 is the second revision of the entry-level GeForce 8400 GS.
Based on the G98 Core (against the G86 of the first revision), it offers only 8 Shader Processing Units instead of 16 but its central unit is higher-clocked. It also features a 512MB frame buffer against the 256MB of the first revision which will prove useful on most 3D applications.
Its performance is on level with the first revision due to the lesser SPU count but the power consumption is much lower of only 25 Watts.
