Will 1080 Ti improve my 4K rendering times?

[Ole Kristiansen]

Hi Ramon !

You have to give more information about your footage and computer !

[Ramon Trotman]

I am running an unlocked i7, 16gb of ram and the 780ti.

[Ramon Trotman]

I7, 16gb, GTX 780ti. Footage is 3840 x 2160.

i7 k – model ? Motherboard ? Harddrive/ssd ? Video footage ? Render codec in Vegas ? More information !

[Ramon Trotman]

I am rendering off a SSD, the render codec is MP4.

The 1080 would only improve rendering with timeline computations of effects, and a very small amount of codec computation. I think the real issue would be the stability of the NVidia’s support of OpenCL. There is also the recent issue that people had with Vegas preview and the NV lastest drivers.

We should be seeing the release of AMD Vega in the next month or so. The Vega GPU will have 8GB of HBM2 and perform at 12.5 TFLOPS. The 1080ti is around 10 TFLOPS.

The fastest CPU, optimizing your motherboard architecture, and running 16-32GB of the fastest stable memory you can stick on your MB will be the best improvements for Vegas rendering. Clearly you want a good GPU that will help plow through the tough timeline effects that benefit from OpenCL computation abilities. The GPU adds certain enhanced math abilities that far exceed the performance of the CPU, but does not handle all aspects of the timeline or rendering like the CPU.

Hard compress h.264/mp4 need a power full cpu ! If you look at the specs. for Vegas and 4K the say you need a 8-core i7 5960x !

So based on what you’re saying here, and Ole’s last response, getting a 1080ti wouldn’t increase my render times that much. Also, the slow render times could be coming from the fact that I have an older i7 (i have the 4820k?)

So what would be my course of action aside from going with amd? Upgrade i7 and get something like a 980?

Is there anyone aggressively rendering 4K? What does that setup look like?

What is the absolute BEST graphic card for rendering 4K material down to HD 1080p files or 480p (DVD) files? I have an AMD Ryzen processor and an AMD RX 580 GPU….but sometimes during rendering in Vegas Pro 13 it does fine and then inexplicably stops and says 0 frames rendered, black screen. Nada. Don’t know what is causing this. Is there a better card that I should use? Or should I upgrade to VP14 or 15, do they handle 4K any better?

I’m hearing about the AMD Vega as well, would this be a good purchase? https://www.amazon.com/MSI-Radeon-RX-Vega-64/dp/B074V9ZK42/ref=sr_1_1?s=electronics&ie=UTF8&qid=1506383462&sr=1-1&keywords=amd+vega

Thanks for your help.

This is an old thread, but I wanted to share my results in going from a GTX 1060 to a GTX 1080 on an 8 core box with 32GB of memory.

It reduced my UHD render times by about 6%. The same video rendered on a friend’s box is 40% faster. He has double the cores (threadripper) and a GTX 1080 ti.

Without systematic testing it is difficult to be positive, but the obvious conclusion is that a CPU upgrade will net you a better return than the video upgrade.
