This is more of a question for my general knowledge, but I always wanted to know the difference between the gaming and professional graphics cards. I used to work for an HVAC company in the IT department and had ordered 2 new PCs for the CAD guys. They requested a certain graphics card that at the time was $700+, but the gaming equivilent was around $300. I see there are GTX equivalent "Professional Cards" that run twice the cost. Could someone elaborate on the difference?

Same hardware, essentially. Preofessional cards are usually just consumer cards with a provision that allows them to use the pro drivers.

The increased price is supposed to reflect the cost to develop unique drivers specifically for CAD apps, and the much-higher level of support that purchasing these cards will include.

It wasn't my money but I was just curious.

So you can't get the CAD specific drivers for a standard video card? What is so special with these drivers?

Never in a million years did I imagine I'd say this... but here goes...

Are you sure Cleeve?

First, the OP asked what the difference was between professional cards and consumer cards. You did not really answer that with the link. Second, Those benches are wrong.

The 3850, even the extreme will not beat the 8800GT, since the only difference between the 3850 and 3870 is the type of ram used IE: ddr3 vs ddr4. Lower clocks as well, but the 3850 core can be overclocked to close to the 3870 core.

Also, that review loses further credibility since you cherry picked your sources. The power graphs and the fps graphs are not from the same place!

A more credible source is right here:
http://www.tomshardware.com/2007/1 [...] age16.html
and it clearly shows that while the 8800GT beats the 3870 in crysis, it does not do so by a huge margin (by huge I mean 30% or more).


To answer the OP: Professional cards are pretty much the same as their consumer counterparts. They cost more because they have some hardware that is optimized to take advantage of programs like CAD. The drivers are also optimized to improve performance for said professional applications.

I guess I am not familiar enough with CAD and other graphic application to know what added hardware/support these cards add to their functionality and make it worth the extra price. Does it render certain images smoother, better, faster? If so what type of images?

My thought is would a consumer card work just as well as the professional models? or am i just being ignorant on this subject?

Heheh. We'll, I'm pretty sure. Quadros are essentially Geforces, and FireGL's are essentially Radeons. Same GPUs.

Hell, in the old days we used to buy Radeon 9500's and mod them into FireGL's by soldering a bridge. Same kind of thing with turning Geforce FX cards into Quadros.

Unless something huge has happened in the past couple years that I wasn't privy to, I'm pretty sure this is how it still works. But hey, I don't specialize in workstation cards. I Could be mistaken.

What benches, and what link? Did someone erase a post, or did you reply to the wrong post?

The pro (Quadro, FireGL) drivers allow for more control over certain settings in CAD apps, and are geared to accelerate OpenGL pro apps instead of games. The last time I read a review with a gaming card vs. it's pro counterpart playing a game, the pro drivers tended to accelerate games slower than the consumer drivers, and the pro drivers tended to accelerate CAD apps much faster than consumer drivers.

It would work just as well. Just wouldn't have the same level of support.

Yes they're quite different I think. It's a different type of application that they're designed for. It takes a different type of architecture to create graphics than it does to play a game. But as far as the components go, they're not much different than a normal Joe Consumer card except for what they're designed for. A professional card doesn't work as well for gaming as far as I know. Maybe I'm wrong

As far as I know, many of those above-mentioned features aren't available on a gaming card. I don't know if they're driver-based or if they're hardware-based features (well, the 1.5GB memory is obviously hardware), but I think it has to do with RISC architecture and keeping things you don't need out of gaming cards, and vice-versa. I just don't believe a professional card will play a game the same way.

I always wondered the same, seeing an Quadro FX at like 4000$ I thought it was a typo before I started doing CAD, I don't know anyone that uses such a card, and I doubt my company will ever look into it (we're using AGP FX5200's, my boss has a 6600 in his lol, sad.. they run Quake 3 ok).

I thought that professional cards also have higher Open GL then consumer cards (gameing cards).

Have to be careful with our terminology here. In the old days, CAD users bought good CAD cards which also happened to be perty decent gaming cards. These came with specific CAD drivers.....but these were DOS drivers. Since Windows AutoCAD and much more so since AutoCAD 2000, the use of special professional graphics cards in plain ole vector graphics AutoCAD is a waste of money.

I buy plain old gaming cards for all our CAD workstations. Where professional graphics cards begin to shine is when doing CAD rendering. When you take a basic CAD file and start doing ray tracing and applying "surfaces" to CAD objects and applying gradient fills, now you start to benefit from professional cards. "CAD" is just plain old vector graphics and doesn't require much processing power. I don't have a single CAD file from any project we have worked on in the last 20 years that I can't open and manipulate on an old NT4 box with a Diamond Fire GL 8 MB graphics card.

Now if I bought and used various AutoCAD add ons to render some of these drawings, with textured surfaces, gradients and light ray tracing and shadows, just about any machine in my office would have me making a pot of coffee and reading a newspaper.

All of the features - except maybe clockspeeds and amount of memory - are software. It's the same core GPU.

For an example, from an Xbit labs review:

"...the new Quadro FX5500 as well as its architectural peculiarities make it resemble the GeForce 7900 GTX gaming solution with slower graphics memory... it uses a new 90nm G71 GPU..."

http://www.xbitlabs.com/articles/v [...] html#sect0


Same GPU. Sure, they add memory to hold more textures, and sometimes tweak the memory and core clocks, but it's the same architecture, same card folks.

All that's changed is the driver: it's a driveer that'll run OpenGL more quickly and stably, because OpenGL is the primary API for CAD. And to support a driver team that's only used on a relatively small number of cards, they have to charge a lot more per card. Hence the colossal price.

Like I said, I've personally changed a Radeon 9500 into a FireGL back in the day... I could do that because it's the exact same card. This isn't theory, it's common knowledge. Before Ati and Nvidia consciously made it difficult to run pro drivers on consumer cards, people used to do it all the time.

Here, check the "Radeon to FireGL mod guide":

http://www.techarp.com/showarticle [...] amp;pgno=0


Like I said... same cards. Different drivers. I know this for a fact because I did it.

So if anyone can offer direct knowledge and proof that Ati and Nvidia have changed this practice and now use unique hardware for Quadros and FireGLs, I'd like to hear it. Because I'm seeing alot of speculation here but no direct experience.
