I was browsing Newegg for new graphics cards and saw from both AMD and Nvidia and found that there workstation cards have that exact same specifications or even less that some of their consumer graphics cards some that go up to 6000 dollars. Whats the difference if they have the same specifications. Would a company want to buy a even faster GPU that would cost them more than half as less than a workstation card. Does GPU and Workstation GPU's have a quality difference and or Gaming difference or different architecture? Thanks
The workstation cards (like nVidia's Quadro cards) are meant for 3D Rendering and CAD type applications. They're optimized for very different stuff. The "consumer" cards are geared to 3D gaming applications.
If you are going to run architecture/rendering applications get a workstation GPU.
If you want to play games, watch movies, encode video, etc... just get a consumer GPU.
Now, as to which GPU to purchase once you decide... entirely depends on other factors:
1) What do you want to do/play with it?
2) What resolution is your monitor?
3) List your other system specs (CPU, RAM, Motherboard, Power Supply, etc)
Workstation graphics cards focus on precision, max resolution, and optimizations for rendering / CAD graphigs. Gaming graphics cards focus on speed, and trade off by providing a much lower precision than their workstation counterparts.
The hardware is very similar but the drivers are very different, the workstation ones have very specialized drivers that handle workstation applications like 3D modeling and rendering much better than their consumer equivalent, but handle games much worse than their counterpart. Whenever nVidia and AMD release new driver versions for their consumer cards, they often list the % improvements for various games, workstation cards do that for professional apps, the extra price helps offset the cost for providing specialized drivers and quick personalized support.
