The GeForce 8400 GS is a very misleading GPU. Like the older GeForce FX 5200, this GPU comes in many different forms. Three of them to be exact. Rev. 1 comes with 16 cores and 256MB of DDR2 memory. Rev. 2 comes with 8/16 cores and 128-512MB of DDR2 or GDDR3 memory. Rev. 3 comes with 8 cores and 512MB-1GB of DDR3 memory. It is also based on the newer Tesla 2.0 architecture. [Jul '21Driftking60]
