The NVIDIA Quadro FX 1800M is a upper mid-range professional graphics card for mobile workstations with about 15" displays. It is based on the same chip as the GeForce GT 335M but can be also equipped with fast GDDR5 graphics memory. The FX1800M is shipped with professional drivers and a special BIOS that improves the performance and stability in applications like CAD and DCC.
The certified drivers guarantee flawless and fast working with professional applications like Premiere, Photoshop, After Effect, AutoCAD, 3ds Max, trueSpace, Blender, Catia, IronCAD, Cinema 4D, Lightwave 3D, Softimage, Mathematica ... A list of all certified applications can be found on the Nvidia.com homepage. Compared to GeForce products, the Quadro FX cards offer a significantly better performance, especially for OpenGL based apps.
The gaming performance should be similar to the GeForce GT 335M, altough gamers should choose a GeForce graphics card because of the optimized driver support (that leads to a better performance and less problems in games). Still all modern and demanding games of 2009 should at least run in medium detail settings (see the GeForce GT 335M page for more gaming results).
The chip is manufactured in 40nm and offers 72 1-dimensional unified shaders. These can be compared to about 300-400 5-dimensional shaders in graphics cards by AMD. These processing cores can also be accessed with CUDA, OpenCL, and DirectCompute to use the calculation power for other tasks than rendering images (for example transcoding videos).
The QuadroFX 1800M also supports PureVideo HD with the new VideoProcessor (VP4) to decode HD videos on the graphics card. This helps reducing CPU load and increasing battery runtimes.
The Quadro FX 1800M also supports the automatic switching between the integrated and dedicated graphics card using Optimus. First mobile workstations do not offer Optimus, as the development cycles of these laptops are very long.

This is a highend workstation graphic chip (for CAD and 3D programs optimized) with DirectX 10 and good OpenGL support - probably based on the GeForce 8700M GT graphic card. It is intended for digital content creators, engineers, earthscientists and other professional 3D applications. Certified drivers grant thecorrect and faster (compared to 8700M) representation of professional programs (CAD, CCD, visualisation software).
