Which card is better for CAD work? - Page 2

post #11 of 30
I'm wondering if the 1.2TereFlops of the 4870 would help with the rendering in CAD. Games may not be able to use the full potential yet, but I wonder if CAD can....other then that VRAM will probably matter, but I think the CPU/RAM will help the most.

Yeah that's a good point about the processing capability. Ugh it just makes my descison harder. I think I'm going to go the NVIDIA route. I feel like a few years down the line, 512Mb of RAM is going to be a limitation, no matter how much bandwidth the HD 4870 may have. Plus, I also wonder if there will be any CAD or engineering simulation software that will take advantage of CUDA in the future. If that's the case then i'll have to go nvidia.

FYI:
One of the reasons the workstation cards are more expensive IS the drivers. They have specific drivers for the programs you run that have been optimized specifically for that application.

Another reason is that _most_ of the Quadro or FireGL cards have onboard HW OpenGL Acceleration.

The workstation cards also have better pixel precision specifically aimed at the CAD market _and_ they actually use the stream processors.

...but yes they are expensive!

The card with more memory will allow you to load more items into memory which will translate to a faster redraw, and move function.

EDIT: One more thing! The FireGL and Quadro cards usually have a stereo out plug for stereoscopic images.

YES! That's what I was looking for. Awesome post.

But I think the problem is PRICE. A quick search on newegg reveals that there aren't workstation cards in the ~$300 range (weird), and that the ones that are close are unbelievably overpriced compared to their gaming cousins. An ATI FireGL V5200 is $390, has a 128bit bus with 256 VRAM. A quick search reveals that it has 1/5 the bandwidth and about 1/3 the fill rate of the GTX 260. I know that it's "optimized" but I find it hard to belive they could actually outperform a GTX 260. But, what do I know.

At my University they run Pro Engineer quite smoothly on Intel GMA950 Integrated Graphics! You are unlikely to be doing much heavy rendering in Pro Engineer. What you will be doing at first will be very basic and require very little processing power at all. You are best to wait till you start doing more complex stuff then getting a new GPU then. It will either save you money, or give you far greater performance. what you have just now is more than adequate.

Your current card is more than enough. My 8800gt Blows away any 3d architectural model i can throw at it,(better than the stupid quadros) and Im sure that my models get waaaay more complex (polygon wise). As for the 512mb on the 4870, i would watch out for that. Most CAD/3D modeling pretty much require you to use a dual monitor setup and anything less than 512 is going to hinder you for sure. This is the main reason i went with 1GB 8800gt but I see why you want the extrea kick with the GPU. What programs are you using? Catia,Rhino,Sketchup,3ds,Maya all run great on my card. You could always wait for the 1GB version of the 4870. You could always PM me because my next card is going to be an HD4870X2. All my professors swear by Apples and ATI for Workstation Graphics. I guess im the nut that fell far from the tree but this time im super interested in the ATI X2 card.

I would bet alot that the GTX260 would beat any FireGL or Quadro card on the market (less than $1,000) on any application that uses OpenGL OTHER THAN 3DS,MAYA and AUTOCAD. I say this because to really take advantage of the quadro drivers you have to have special drivers made for that card. I learned this the hard way. You really wont see a gain with the workstation cards unless you use these programs. They also game crappy.

My 8800GTX was fine under 3dsmax and C4D. Only complain was under high poly scenes it would still stutter.
If you really want to, just softmod your card to get the performance of a QUADRO (noob called it a quattro) haha.

Better Pixel precision? No. These are digital devices, not analog. And they use the EXACT same processors as the gaming models. They are tuned to apply more of their power to Anti Aliasing for faster performance with CAD, yes, but they aren't more accurate in any way shape or form.

And OpenGL acceleration? Gaming cards have it built in as well. They've had it built in since the era of the Riva TNT. Just read up on the Doom3 engine if you don't believe me.

So that brings everything down to the drivers and BIOS. And that is very easy to deal with (click that ).
