NVIDIA has rebadged its GeForce GT 520 and GeForce 510 GPUs for OEM clients. The GeForce GT 520 is rebranded to GeForce GT 620 and the GeForce 510 lives on as the GeForce 605. OpenGL driver support has been updated from 4.1 to 4.2, and the cards also have a slightly different power rating.
What has changed (other than the amount of memory supported) from the previous generation cards is the maximum power draw. GeForce GT 520 and GeForce 510 both had a maximum power draw of 29W. In contrast, GeForce GT 620 has a maximum rated power draw of 30W, and GeForce 605 has a maximum rated power draw of 25W. Other than that, the cards have every sign of being remarks of the equivalent Fermi cards.
