My PC is not using 100% of GPU

Hi guys, I have a PC without GPU and render time was very slow.

So, I got with a friend one Geforce GTX 1060 6Gb and install it today.

The render time reduce a lot, from 15min to 6min for ex.

But the use of GPU is not in 100%, the configuration at General/Preferences is Hardware Aceleration with CUDA.

The memory in GPU was very low to, but my output file was only 650MB.

Now I need to buy a GPU to me, and return this to my friend.

With I´m not using 100%? It´s because my CPU or RAM?

If I buy an GTX 1050ti the perfomance will be the same in my case?

I´m glad with 6min of render, and don´t want to change the PC.

In my home I have anothe PC, with a core i5 8400, maybe with this CPU should be faster?

The files are in my server, and I acess them directly to work by the network.

But I noted that Premier do a buffer in my PC, and only export the final file by the LAN at the end, so, my 100Mb LAN should not be a problem.

My PC:

Intel Core i5 4460

Asus H81M-A/BR

8Gb DDR3 1666Mhz

SSD Kingston 120Gb SV300S37A120G

100Mb LAN

Thanks!

    Your i5-4660 is only 4-core with no hyperthreading where the i5-4800 is 6-cores also with no hyperthreading, more CPU power. so yes the GTX 1060 will do better but most people recommend i7 CPU's with hyperthreading for good results editing Premiere.

    If you really want to see the total CPU, GPU, and storage analysis, download and run Premiere Pro BenchMark (PPBM) and run it and SUBMIT the results.

    Not everything uses CUDA... read this

    Thank you, probably my video is not using all effects that need CUDA, and it´s using more CPU instead.

    I will try the same GPU at i5 8400, and check if the results are better.

    Maybe I can change the CPU´s, and increase the RAM do 16Gb.

    I've sent the test today with my home pc (i5 8400: 705,"150","54","147", Premiere Version:, 12.0.0.224)

    Could not perfom the first test with my work pc because at ssd I have only 25Gb free, and the first test need around 37Gb.

    And by the network was very slow because 100Mb LAN.

    But in the second test and third, was faster than my home pc.

    I think because 1060 instad rx480.


    Here are the results in the Output.csv file.

    "705","150","54","147", Premiere Version:, 12.0.0.224

    1. It is not practical to run Premiere  pro editing over an Ethernet attached disk drive as you can see from your 705 seconds score which is 52 MB/sec write transfer rate.  You really desperately need a local SSD for your Project and Media files.
    2. i am going to jump to the last score above (CPU only intensive test)  which is 147 seconds which is an impossibly low number for any i5 CPU.  You must have not followed the setup instructions.
    3. The third number is probably in the ball park but with the above two problems may not be valid.  And with the GTX 1060  both the second and third numbers should be significant lower.
