Graphic card possibility

[cmittenaere]

Hello everyone, and thank you in advance

I currently have a gtx 690 (2 gpu). It's nice, but I would to invest.
So are there any real performance difference between the calculation pro graphics cards and mine?
And is it better to buy a second identical card? or invest in a pro card?
Octane use correctly cards, if I add a pro card in addition to the GTX?

Thank you in advance and sorry for my french (I'm french).
Thank you thank you!

hi, cmittenaere.

There's no real benefit running PRO cards (Tesla or even Quadro) over GTX as technically they are more or less based on the same inner parts. Teslas & Quadros are tuned not so aggressive, thus they might run a bit cooler, that helps for stability when cards are 24/7 under full load, but..none of their features like ECC memory, or DP performance, or even optimised drivers makes no difference in Octane at all =) so from the value perspective You get way better deal buying top of the line GTTX cards like Titans or 780s, rather then going to PRO line..

Though here's one thing..if 6GB if somewhat not enough for You, the only way to get more vRam is to step for PRO line as they give more RAM, but speed wise they are going to be same (or even slower).

I would consider buying really expensive PRO card if I would need these these optimised drives for CAD type application or something like 3dsMAX, & would like to use card for very heavy scenes rendering in Octane..but overall, sticking to Titans/780s seems seems the best deal so far.

If You OC them, & to keep them properly cooled (maybe with water-cooling) You can squeeze more performance out of them, what gives You overall better value & more pleasant operation because of lower noise output =)

hope, that helps, but if You have any other questions or doubts simply drop a line & we'll try to help You out making a deception for investment =)

Hello, I want to buy another GPU to my computer. Right now I have a Quadro k4000.

What would be the best card price/performance right now? Gtx 780 ti?

thanks for your help

depends on how much vRam You need =)

[JavierVerdugo]

Thanks for the fast answer.

What is the function of Vram? Is there so much difference between quadro and 780 or titan?

I understand that Vram is for very large detailed 3D scenes, right? I work with Cinema 4D and I work on motion graphics scenes, so I think I don't need so much VRAM, I don't know If I'm right in this point.

Sometimes I make a logo animation, some character animation, or mograph, but there is not huge comples scenes like render a whole street with a lot of people walking and cars, etc.

I was thinking to buy Quadro K4200 but then I read this post and others which talk very good about GTx 780 Ti, also people talk good about 980 (people talk that need better driver improvement by the way). If I get the same performance with Quadro k4200 than Gtx 780 Ti, but I have more Vram just in case I need it, it's ok for me to invest 200$ more dollards. But If I'm going to have better performance (fast renders) with Gtx 780 Ti the thing changes.

vRam on GPU holds Your entire scene, pluss Your resolution is dependent on vRam You have..if You buy small card, upload big model & crank up resolution You might not be able to render anything at all =) to monitor how much You scenes typically use go to properties & You'll find a tam with information about opened scene =)

Don't buy Quadro, unless You're going to use if screen too =) however the best is to get something like 780Ti (if You're happy with 3GB of vRam) - for way less $, this card is going to be twice faster than the Quadro (k4200) You want to buy =)

now keep in mind that not all cards are equal, there are reference & non reference models. Later has different cooling solution usually that has it's pros (You can over clock card a bit & get more performance), though in cramped cases where You put cards side by side, these might not work perfect & might even start throttling down (& You start loosing performance). So there are things to consider when You're investing into hardware =) just don't think that more expensive quadros/teslas will be faster =)

drop some more info about Your build, what amount You're looking to spend & guys can help You out a bit =)

Ok thanks for the info.

I have 500-900€ to invest in a new gpu.

So If I understand correctly, GTX 780 ti > GTX 980 > Quadro K4200 in terms of fast render.

Antoher question, if I would need supose, 4 or 6 GB of VRAM what would be the best option.

Again thanks for your time

I just check the Titan Black and Titan Z, they have more VRAM If I'm right, it worth the over prize?

don't get hooked, TitanZ is dual GK110, under clocked.. (I've wrote a bit about that a while ago - TitanZ for OctanRender) so, it terms of value, it's not the best deal..unless Your really trying to cramp a lot of power one box or building mITX system, where only single PCIe is available (need to write a second look on it, especially after recent price cuts! =) however two single GPUs based on gk110 will be faster.. & return better overall value.

(if You haven't read provided links) these 12 GB in octane is 2x6 'cos scene should fit into vRAM of every GPU =) so basically You have two 6gb cards (under clocked 780/titans in one triple slot form factor).

Octane is not yet performing good on 980 & personally I wouldn't recommend this card for it.

780Ti is unbeatable as single GPU in terms of performance out of the box (at the moment) & sits in You price range, but have "only" 3gb, if You want more Titan or TitanBlack is the only option utilising the same chip (& offering same performance), but the price of those is higher.

There was 780 6GB model, but it's phased out for around 600$/Eu - that's the best deal in terms of value as it offered good speed & plenty of vRAM. Now it's getting hard to find them, grab one if You spot any!

& remember that 6GB 780s all have non reference cooler design, so You need some space for them to breath to get the most of them =)

for new Maxwell based cards, well.., I'd advise to wait & see how they are going to perform..- If You're up to 4GB cards, the 770 is an option - that's impressive card offering good value, coupled with nVidias reference cooler.

hope that helps =)

Hello Glimpse, I really appreciate your help.

I decide to buy GTX 780ti and wait some time for the new maxwell cards to see how they works in future driver and octane new versions.

Right now Gtx 780ti 3gbRam is perfect, exactly what model would you recommend me? I saw different prizes in the same graphic card but different distributors going to 450€ to 750€.

Could you tell me a specefic distributor, I would really appreciate that. Many thanks for your time.
