gtx 980 vs gtx titan

[Alex_M]

Thanks but my budget allows just for GTX980. I asked since I saw a used Titan Black with the same price as 980. Anyways, I just ordered the GTX 980 since it's brand new and has full warranty. Did I make a good choice?

Hi

I had the exact same issue with some new workstation we build few weeks ago.
Dual xeon i5-2670 V2 with 128Gb of ram, so not small workstation.

Because people where saying so much good about the gtx cards (and so bad about quadro), I went for few of them on the new workstations.
Tried our old GTX 680, then the GTX 780 Ti, then we bought the Titan, thinking "it's going to change everything".
For a average scene, it's ok and you really don't see "any" difference with GTX cards, true! And I respect that.
But once you hit big scene (like we do and that's why we went for workstation like that) it just doesn't hold up.

Then went with the Quadro K4200, and there, incredible, just blazing fast, actually, we should not have changes workstation at all.
So now we are going with K4200 on all the workstations, even the old ones. It's just not comparable.

I tried to explain this several times in other posts, but ppl seems to just shut me up and tell me quadro are sh*t.
I know, I was like that as well, till I saw how even the latest Titan VS a "cheap old" quadro is performing...
After that, I had a look to few benchs, and it seems the K5000 or K6000 will only bring 5-15% viewport performance gain compared to the K4200.
For us it's definitely not worth it (or at least not in the project we are working on.)
The Quadro is already 10 times faster than the Titan.

Sorry, I'm not a brand-fan but I have to be honest on this one.
Mate, don't even think about going GTX for big scenes and viewport performance.

I guess I will be shut down again, but this is just my 2 cents and I hope this will help you make the right choice, because I saw it and I couldn't believe it myself.

Again, if you want to do RT, go for the GTX980, I'm even thinking of buying 4 of those in the next weeks, no doubt they are way better for rendering than quadro.

Cheers

Quadro cards are not shit they are just a bit overprized. 3dsmax DX viewports (and pretty sure nitrous does, too) uses cached directx
meshes. After all that means whatever fits into the memory is pretty much the same speed. If it goes beyond that, the scene is more or less unusable and one better switches to opengl. Now the quadro and titan cards have huge anmounts of memory wich of course
enables you to load much larger scenes at the same speed. If you are constantly working on very large scenes than it´s probabely a
good idea to invest the money, if you don´t you´re wasting a huge a amount of money for 0 benefit. I´m Speaking just about viewport speed. It´s probabely a matter of personal taste if it´s worth spending that much more for VrayRT. I´m working constantly with
1-2gb STEP files and my "old" gtx 760 works like a charm.

alex_m - yeah, it's the best card on the market right now. the titan x is technically better, but imo not double the price better.

Can someone clarify that the GTX980 works with CUDA? I am running maya 2015 and latest nightly of vray.
I get errors trying to run rt in cuda mode.
Someone on youtube says you need a special build, via email, but support would not reply to this.

Advice would be super, I may have to install my old cards otherwise.

edit: I just had some bad xgen/textures, new scene worked fine.

It does work fine with the latest drivers, but it would be best to contact our support guys - they might arrange a remote session with you to check what's going on.

Best regards,
