render Cpu render vs Cpu + Gpu render no difference (after effects)

[robin_GameZiseFX]

So a long time ago I tried to enable my gpu(gtx 970) to render in after effects and saw almost no difference between 
"cpu(i7 5820k)" and "cpu(i7 5820k) + gpu(gtx 970)"
also no difference between
"cpu(i7 5820k) (multiprocessing)" and "cpu(i7 5820k) (multiprocessing) + gpu(gtx 970)"

 

I searched some video's and came at this video called
"Premiere Pro CC - CPU vs. GPU Acceleration"
In the benchmark results there were almost no to no differences between rendering on cpu(i7 5820k) or cpu(i7 5820k) + gpu

I would like to get an explanation why there is no differences and maby also a way to get it working better.

 

My videocard is enabled in after effects.

Ik but that was on the cpu place while It's also on the gpu place, sorry if it annoys you.

Only certain limited effects, some 3rd party plugins and 3D ray tracing are GPU accelerated. If you're not using those then all the work is done by the CPU. That's just how AE works at the moment.

Okey I get what you mean but why in the video called " Premiere Pro CC - CPU vs. GPU Acceleration" it says by the other cpu when rendering with gpu it's less than only on cpu. and by the I7 5820k. I think also because the iGPU

Premiere can use the GPU the encode (to my knowledge haven't used it in forever), AE can't use it for the main encoding just for certain effects. And the 5820K does not have an iGPU.

I know that the i7 5820k has no igpu i tought maby that was the issue.

 

these results were at rendering in premiere

and still not that many improvement in render.

GPU can help render in Premiere but does not accelerate renders in AE (IIRC). Also that graph is looking at a GT630 which is a very weak GPU, you wouldn't expect it to make much of a difference at all anyway. I'm shocked (and a bit skeptical) it made that big of a difference for the 2600k, they must have been rendering a video with a heavily GPU accelerated effect.

It is not my results it's from a video I saw when I were searching things up , This is also in premiere and not in after effects. but still wanted to know why it made that diffrence and not with the i75820k. I have a GTX 970 and has many cuda core's and it would be nice if i could use them to render in combo with 8 threads to render.

that would speed it up from the only 8 theads rendertime of 4 hours to about 1 to 2 hours.

 

So when i saw that video I also realised almost no improvement when i cantivated my gpu only with moving the timeline thingy.

 

Still hope they will update the render engine or waithing on 3th party software that make it posible to use gpu 80% or something with cpu 80% to 100%  so it will reduce the render times.

 

for example in cinema 4D, if I render it is rendering at almost 100% cpu load but when you use a 3th party software called "octane render"  you can use the gpu to and thats a nice function.

 

thanks for your time. and still idk why it made that difference in rendering you should say if there is a reduce in render time than it should be same by the other one ^^.
