Question about (my) Hardware that will speedup rendering?

xXQuatroXx

Hi there, I have a single msi 970 gtx a intel 4790k cpu and 16gb of internal ram. I've gather some info stating that if you dont have a xeon cpu the cpu helps out only a little bit. Not even worth mentioning in some forum they say. So besides the cpu (i dont want a whole system upgrade) what can i do more to speed up/boost quicker render times? A second 970 gtx? Will it realy make a difference and what time saver wouls it be? How much less of a time will it take to render? And if i but a second card or a third do i need to run them in SLi? Is internal system ram of some importance? I can upgrade for an other 16gb total 32gb but is it realy needed? Does it have any effect on the rendering process? And about my cpu does boosting my cpu (overclocking) have any effect on the rendering process? Any help.would be great ;) Thanks

Get a card with more VRAM. You only have 4GB, and 1664 CUDA cores. If your screen also uses your card, you have even less memory available for rendering. If you put three clothed & haired people into a scene, chances are your scene will not use the card, but switch to CPU.

Hi BeeMKay, thanks for the quick reply. But what if i use 2 card with both 4gb vram thats 8gb of vram and a third card maybe... Wont that be good too? Instead of a more exspensive single card? And wbat about the pc's internal memory? Now 16 gb is upgrading also usefull for rendering or will it only use gpu/cpu?

The video RAM doesn't stack - the maximum is the lowest amount of RAM on any one card in your system. You'd still max out at 4gb, thought you'd have access to more CUDA cores. Increasing your system RAM may help DAZ Studio run a little clearner, but it won't help your rendering time. For graphic scenes, the amount of RAM on the video card is more critical than the system RAM.

No, if two cards have diffrent amounts of RAM and a scene is too large for one and not the other then the one that can handle it will still be used.

Really? I could have sworn I read that it was constrained by the smaller amount. Glad to be wrong!

Richard is right. If you have two cards, one 4GB and one 6GB then a scene which requires 5GB will only render on the 6GB card.  I would suggest one of the newer 10XX series cards, rather than another 970, if your budget will run to it.

Cheers,

Alex.

Already have a 1070ti waiting to be installed. Thanks!

Just curious, but if 2 cards are identical would both processors work in tandem, or DS would only use first GPU?

Example: I win the lotto & Santa brings me two 1080-TI's or something.

DS will use both if the scene fits on both (uness you don't have them both checked in your Render Settings).

Thanks.  That's useful to know for future upgrades.  Although I doubt I be getting any matching 6 numbers soon.  ; )

So if i have a 970 using for monitor(s) and a 980 ti for rendering. The card will use its 6gb? Or will it go back to 4gb because the lowest card i have installed is 4gb. If this is the case its of no use putting those 2 cards together because the 980 ti would not use its full potential. Or will it only be like this when in iray render settings i have both cards selected. That the lowest vram will be used? If this is the case then i would only select the 980 ti and when needed the 970 if more vram is required. Please let me know

If you are using a 980ti for rendering this should work fine, as long as your scene fits within its 6GB of memory.

If you select both GPUs and your scene requires more than 4GB then it will render on the 980ti only and ignore the 970.

Hi JMC

The cards aren't used that way.

Think of each card as completely seperate with each card communicating only with Iray and completely unaware of the other cards existing.

The cards can not communicate with each other or access each others memory! The amount of memory on one card has no effect on another card.

xXQuatroXx

Thanks guys ;) now to find a 980 ti for a good price. Just below the todays market value would be nice. Happy rendering!

xXQuatroXx

Guys what is the minimum recommendation of powersupply i would for have both a 970 and 980 ti in my system..so 980 ti will only be used for rendering. Monitors will be hooked on the 970. 2 of them. I have i7 4790k.

xXQuatroXx

Nevermind found it at : https://outervision.com/power-supply-calculator Entered all the stuff i had in my pc. 750 is enough. I have a 800 so im safe.

How do i see if the scene is above or below 4GB?

By trying to render. Sorry, there isn't really a way to havea  dry run.

All so got a 980 ti now next to my 970. 970 runs my system and 980 ti purely for rendering. Rending a single image on 1080P has come down to 5 to 10 min. But when wanting to put out animation like 100 frames of only 280x500 pix cost me 2 hours... ok it did have some background and render settings where set on 80% and quality on 2. On 1 did give me to much grain. Was a rest how ever. Needed to make a GIF on tumblr with in the 3mb limit and pix. So how do i improve render times and on higher res?

Edit:

Put Qulity render on off, rendering now at 720P with 1750 (1750 because of lights and glossy skin that reflect lights abit = less granny) samples and no enviroment/background.

Render now at about 2 min and 14 seconds

Anitmation for turntable 1 time round is 100 frames which will be about 3 hours and 30 min. (Still to much if you ask me, but better then with the GTX 970)

And this time output is set to "image series". Much better quality then movie, plus can quit and start at the next frame any time.

No back ground with PNG so can add BG when compiling the files to animation in movie editor (Adobe Premiere Pro)

 

Adding to GTX 970 to the render moves down to 1 min and 15 seconds.

 

SO GPU wise. A second GTX 980 Ti? 

How much would i improve rendering time?

 

CPU wise (instead of GPU):

What processor would do a nice decent job turning down the render times, and then especially on 1080P or 4K?

Xeon processor? if so what type? Dual processors ?
