So have I, for years, including literally side to side with a monitor switcher hopping between the two workstations (IE: one with a 580 and one with a 4k).
Yes, when people compare 580/680 with a lower end or old quadro they are underwhelmed. I ones did a comparison between a quadro 5000(work) and my GTX 285(home) and my current 570(home). The difference was like this: GTX 285 2.1 mill polys at about 15-16 simple shading
GTX 580 0.4 mill polys at 2-4 fps. Quadro 5000 40 mill polys at around 80 fps. I scaled the scene to match the capability of the cards, instead of just depend on fps alone. i don’t remember the exact numbers but that was the general behavior. The Quadros are faster or rather the Gforce cards are slower, when handling double sided lighting and return pixels in openGL.
See, that’s one of the worst ways to test a videocard you could possibly think of, not to mention rather dated.
That’s just not how the videocards or their drivers work, but anyway…
Here is a rather contrasty test, where they are comparing two cards side by side. a geforce 670 (a card on the heady side), and a Quadro 600 (A card in the very low end of Quadros) and the Quadro still eats the geforce in that particular task. http://www.youtube.com/watch?v=kl4yNCgD3iA
You are aware of the fact the 6xx is DP crippled, and therefore can be made to artificially perform horribly in some tests, right? The 580 will absolutely BLAZE by a 690 in example if you toss them on a DP Fast Fourier Transform that’s using DP.
The Titan doesn’t have the crippling, which lets us hope the 7xx, based on the same silicon, won’t either.
That’s also why many people consider the 2xx and the 5xx the best gaming card gens for 3D.
Regardless, let me re-state, no, quadros aren’t faster, they are exactly the same cards as the GTX, recently on lower clocks, with their on board id changed by a resistor (see resistor hack thread I posted where a 680 is turned into a k5000) to let drivers throttle features, and occasionally (depending on line up) some cores lasered out or in.
The Titan will smoke a k5000 in day to day use with Maya in my experience and that of others.
The generic statement “quadros are faster” is so fundamentally flawed when made as blanket statement it’s annoying beyond belief to see it constantly repeated by people barging in and out when it’s been disproven a ridiculous amount of times at this point.
