I think you've total epic failed to understand completely what you're talking about.
Do you know what $1400 buys you? The hardware is nearly identical, you're paying for software (drivers). Software price is not so much based on volume; it's based on what the target buyer is willing to shell out.
BTW, gaming cards often are available with higher clock-speeds, thus outperforming their "workstation" counterparts, if you want to focus just on the "cards". Go google quadro conversion.
Sorry to ruffle your feathers, dude. I did leave it open ended so you should not shoot off wild baseless accusations. You haven't a clue as to my knowledge. If you have a few minutes I will school you.
So to be fair, I should have also mentioned that workstation cards would not game well. As to the asking prices of workstation cards, you are partially correct. It is mainly a result of lower sales numbers but is not anything to do with what a buyer is willing to "shell out". It's about volume. Business 101.
There are a number of strict graphic requirements for CAD/CAM/CAE applications such as NX, Pro Engineer and Catia. The certified HCL lists are accompanied by certified OS levels, certified patches and very importantly, certified graphics drivers. Strict adherence to OpenGL, anti aliasing and other standards is mandatory. Every single driver has to be certified.
As for higher clock speeds of gaming cards outperforming gaming cards, well, they don't outperform much of anything when you can't see your model on the screen. Gaming cards just need to make things look nice and have a decent frame rate, that's it. Workstation cards have higher graphic requirements when it comes to CAD/CAM/CAE applications. I know people in CAD groups who use gaming rigs. Usually the performance is bearable but sometime there are driver conflicts and the graphic issues can range from minor anomalies to not working at all.
You seem sort torked about pricing. All I can say is they are two totally different worlds. It's not uncommon to spend $20K-$40K on top tier CAD/CAM/CAM software. Add another $5K-$15K for a 8-core Xeon rig with lots-O-ram, a 3D controller and a ridiculously large monitor. Throw in some database collaboration software and other support software too. There are some people making workstation rigs using four socket server boards.
How much to build a nice gaming rig? Don't forget to add 20 bucks for Counter Strike Source.
