nvidia CUDA 3d video rendering ?

dafuqawew · Mar 9, 2014

hey guys how fast is cuda for rendering than a CPU ??

ak47jar3d · Mar 9, 2014

A lot faster. It depends which cpu and which gpu. If Cuda is support, your rendering times will get cut by more than half in my experience.

ak47jar3d :

wow thanks for answering . so whats ur GPU and how many cuda cores you have and how much should i have ??

manofchalk · Mar 9, 2014

Kind of depends on what your doing and what you have, there is no way too answer "how fast will X be in comparison to Y doing task Z" when you don't define any of the variables.
It will speed up your rendering if your software supports it, that much is guaranteed.

I would say an i5 processor, gtx 760/770 and 16 ram is the ideal machine for rendering extra high quality video. I can tell rendering time will be very fast with this configuration or a similar one. I have seen people use multi card solution for rendering as well, but these configurations are too expensive for me to recommend.

ak47jar3d :

whats ur specs ?? do u do rendering ?

ak47jar3d · Mar 9, 2014

Yes. I do rendering, but nothing professional, mostly in game footage to upload to YouTube. I have i5 4670k, amd 7970, 16 gb of ram now, but I used to have 760 before it changed them, and the rendering times on Sony Vegas pro where a lot better with 760 despite 7970 beats it in games.

ak47jar3d :

so how many CUDA cores do i need for 3d rendering ?? maybe the minimum ??

ak47jar3d · Mar 10, 2014

I would say at least say 1000, but then again you can never have too many Cudas cores for 3D rendering.

ak47jar3d :

how bout 96 is it good ??

dafuqawew · Mar 11, 2014

ak47jar3d :

how bout 96 cuda cores ?? what should i buy gt 630 1gb gddr5 with 96 cuda cores or gt 630 kepler 1gb ddr3 with 384 cuda cores ? i do rendering thats my only budget , so which do you recomend and which is faster with cuda ??

ak47jar3d · Mar 13, 2014

You can, but expect to have a book handy becuase rendering times are going enormous.

what should i buy gt 630 1gb gddr5 with 96 cuda cores or gt 630 kepler 1gb ddr3 with 384 cuda cores ? i do rendering thats my only budget , so which do you recomend

ak47jar3d · Mar 14, 2014

What is your budget? I pretty sure all 630s have the same specs.

dafuqawew · Mar 15, 2014

ak47jar3d :

thats my only budget, and NO the GT 630 kepler card has more CUDA than a non kepler GT 630. but the kepler card is ddr3 and the non kepler card is gddr5
info about GT 630 : http://www.geforce.com/hardware/desktop-gpus/geforce-gt-630/specifications
GT 630 1gb 128-bit GDDR5 : 96 cuda cores
GT 630 1gb Kepler card DDR3 64 bit- 384 cuda cores
just tell me the which is better for my needs(above) and which should i buy !! thanks !!

ak47jar3d · Mar 15, 2014

Gt 630 Nvidia Kepler is about 15 percent better and only needs 25w to run, so definitely go with that one.

dafuqawew · Mar 15, 2014

ak47jar3d :

but the kepler card is slow compared to GDDR5 one Even though it has 384 cuda cores :

GT 630 (Kepler) GT 630 GDDR5 128-bit
MEMORY CLOCK : 1.8Gbps 3.2 Gbps
Memory Interface : DDR3 GDDR5
Memory Interface Width : 64-bit 128-bit
Memory Bandwidth (GB/sec) : 14.4 51.2

so what do you think ? which should i get ?? thanks

ak47jar3d · Mar 15, 2014

You really cant compared cards with different architectures in most categories becuase the specs won't be proportionate to preformance. Kepler is much more effective than Fermi and thus making the gt 630 Kepler a better preformer. I will stick to my recommendation: Kepler 630.
