[tcMag] AMD announces 1 TeraFlop-breaking stream processor - Page 4

post #31 of 36
Makes sense regarding stability - if I do try a softmod to see how it runs with CAD software, I think I'll actually underclock the card a bit just to ensure stability, since that's exactly what they do for the Quadro lineup. It would be excellent to pick up an 8600GT and softmod it into a Quadro if it worked. Get a $1,000k card for $100. The company I work for has been on a budget since it started, so any money saved is very much appreciated by upper management.

You should start a thread talking about/showing results. I would interested to see what happens, plus trying to find info about workstation vs desktop is near impossible.

Edit:I should say finding a thread with hard facts is near impossible. I haven't found one that shows any graphs or comparisons of the two.

If you want to try out softmodding, then ATI is the way to go... Their gaming-workstation difference is a more easily transversed jump, for whatever reason.

And btw, for the naysayers, I can provide proof... hardened proof.. of the hardware difference between gaming and workstation:

1. Render a scene using Gelato (either with mango or amaretto) using the GeForce, not optimized.. but it looks acceptable.

2. Render the same scene using the soft-modded GeForce.. 99.9% of the time you will end up with a completely scrambled image (I've never witnessed the .1%, but i'm sure someone.. somewhere has)

3. Render the scene once more using a real Quadro. It will not only render, but if you put the .iff's (ok, so I'm partial to Maya.. but Targa would be noticeable as well) side by side, there is almost always a difference in render accuracy.

To notice the difference, look for:
- polygon -> subdivs that were converted back into poly
- any baked texture
- reflections (look in the Phonngs, there are some nice little jaggies that will show)

There is in fact a difference in the precision of these cards, much the way that converting a Lossless audio file to mp3 still sounds the same, but misses that airiness and pristine sound of it.

Honestly though, if you're serious about working with the stuff, you've already dished out thousands to Autodesk for AutoCAD, 3DS, or Maya... whats another grand to Nvidia?

Well, if you read my latest post I said that I wasn't looking for rendering quality for images, I'm looking for workstation cards for the use in CAD systems. While you do bring up good points for the quality of renderings, none of them apply to a workstation card for a CAD application.

Also, regarding the ATI cards, why are they easier to softmod? I was going to use a GeForce simply because SolidWorks (I believe) doesn't play very nicely with ATI cards - at least the release we have.

You get these crappy results when you try to mod the nvidia cards because nvidia has put in some extra protections in newer cards to intentionally give bad output with a softmod. Random crashes soon after loading any opengl software, along with this sort of thing. ATI has implemented no such protection, so the output is the same as a FireGL card. Of course, FireGL is obviously not compatible with Gelato, so you can't repeat this test.

^right he is. I wouldnt call them "protections" as much as shortcomings though.. My FX4600 is an 8800GTX, but it just isnt pushing the same info through its pipeline(its also got a single power connector, as opposed to the GTX's two)

And for GuardianOdin, I'm pretty sure the FireGL's are certified for SolidWorks now.. but i also know there were issues with them in the past (driver related bits and pieces around the x1950's workstation equivalent days, IIRC)

I'd read into exactly what gets calculated by what in the software you'll be working with. I love my card, but when in the Maya workspace, it gets me about zero gains as the entire mesh is CPU based (as is any environmental dynamics... its sad when you're still going on coffee breaks with an OC'd quad just to preview collisions in a viewport)
