NVIDIA NVS 4200M
The NVIDIA NVS 4200M (or NVIDIA Quadro NVS 4200M) is a business graphics card for laptops which is most likely based on the same core as the GeForce GT 520M. According to the Nvidia Homepage, the 4200M is allowed to be clocked up to 810MHz, compared to the 550MHz of the GT 520M. However, the clock rates of the NVS 4200M in the Dell Latitude 6420 is similar to the GT 520M.
The NVS series is optimized for business applications and stability and may therefore perform a bit worse in games due to the special drivers and BIOS optimizations.
The gaming performance may be a bit worse compared to similar clocked GeForce cards due to the stability optimizations of the NVS. In theory the raw performance of the chip is enough to run current games of 2010/2011 in low-medium details and resolutions.
As the GT 520M, the NVS4200M should support PureVideo HD (VP4) to accelerate HD videos and OpenCL / CUDA / DirectX Compute to use the render cores for other applications.
The graphics card supports HDMI 1.3 up to 1920x1080 and Multimode DisplayPort up to 2560x1600. Furthermore, 7.1 channel HD audio can be trasmitted over the HDMI port.
