NVIDIA Quadro 4000M vs NVIDIA Quadro 2000M
NVIDIA Quadro 4000M► remove
The NVIDIA Quadro 4000M is a professional workstation graphics card based on the Fermi architecture (or more specifically, probably the GF104). Unlike the 5010M, the 4000M does not support ECC memory and dual-precision (DP) floating point calculations.
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications such as CAD or DCC. As a result, multiple scientific or business disciplines can make use of the workstation GPU. The OpenGL performance, for example, should be significantly better than consumer-oriented GeForce graphics cards of similar specifications.
The shader / CUDA cores can be accessed using DirectX 11 or OpenGL 4.1 for graphics rendering or DirectCompute, OpenCL, AXE, and CUDA for general purpose calculations. Due to the new Fermi core, the 4000M should offer higher performance in general purpose calculations compared to its predecessors.
Furthermore, the Nvidia Quadro 4000M is compatible with 3D Vision Pro, a new software solution by Nvidia for stereoscopic output.
The 4000M supports Nvidia Optimus in order to automatically switch between the integrated graphics card and the Quadro for power-saving purposes. Whether or not this feature is supported on a laptop, however, is dependent on the laptop manufacturer.
Similar to the GeForce GTX 480M, the Quadro 4000M is specified at 100 Watt TDP and is therefore only found in large laptops such as the Clevo D901F.

The NVIDIA Quadro 2000M is a professional workstation graphics card based on the Fermi architecture (likely the GF104 or GF106). It offers the same amount of shaders like the GeForce GTX 460M, but only a 128 Bit memory bus for DDR3 memory. The slow DDR3 memory in particular could be a bottleneck to the GPU
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD, DCC, medicine, or visualisation areas. OpenGL performance, for example, should be significantly better than GeForce graphics cards of similar specifications.
The shader/CUDA cores can be accessed using DirectX 11 or OpenGL 4.1 for graphics rendering and DirectCompute, OpenCL, AXE, and CUDA for general purpose calculations. Due to the new Fermi core, the 2000M should offer high performance in general purpose calculations.
Furthermore, the Nvidia Quadro 2000M is compatible with the new stereoscopic solution by Nvidia, NVIDIA 3D Vision Pro.
To automatically switch between the processor graphics card and the Quadro, the 2000M supports Nvidia Optimus. The implementation of the technology into specific notebook models is dependent on the laptop vendor.
The Quadro 2000M is specified at 55 Watt TDP and is therefore best suited for 15.6" or greater laptops.
