Premier Export Not Maxing Out CPU

[hixrat]

I have noticed recently (I do not check every render) that my Premier render is only using 30-40% of my CPU 55% Memory and 30-40% of my GPU. In the past it has been at 100% CPU usage for almost the entire render. It pains me that my sytem is not being used to its full capacity to shred through renders. What are some things I should look into?

 

System Specs:

CPU: AMD Ryzen 9 3900X 3.8 GHz 12-Core Processor

Motherboard: MSI MPG X570 GAMING EDGE WIFI ATX AM4 Motherboard
Memory: Corsair Vengeance LPX 32 GB (4 x 8 GB) DDR4-3200 CL16 Memory
OS DRIVE: Samsung 970 Evo 500 GB M.2-2280 NVME Solid State Drive 
EDITING DRIVE: Kingston A2000 1 TB M.2-2280 NVME Solid State Drive
Video Card: MSI GeForce GTX 1660 6 GB GAMING X Video Card 
Power Supply: Corsair RM (2019) 650 W 80+ Gold Certified Fully Modular ATX Power Supply

You probably have some GPU-accelerated effects, and the CPU is just waiting on the GPU to process them.

My GPU is never maxed out. There are not a ton of effects on the timeline. It is mostly BRAW 12:1 4k  footage. There are some overlays with transitions but nothing crazy.

Okay then yes that will be processed on the GPU. And it's normal for the GPU not to show 100% since that process will only use certain features of it.

Interesting. I updated my chipset drivers and it is doing a lot better. I was under the assumption that for my use case (mostly editing in premier with light graphics) I would not really benefit significantly from a more capable GPU but from what you are saying is that certain features of my GPU may be bottlenecking my rig. Thanks for the help. Greatly appreciate it!

Not using 100% of your GPU.

He MEANS, there is a dedicated chip for Media Encoding and Decoding.

Processing tasks still take time, esp when its 4K media, your CPU is waiting for your GPU yes, but your SHADER units are not the bottleneck as you might think.

Its just processing time the GPU needs (remember its getting fed data constantly the entire encode timeline via its media codec engine then sent back out, likely with many operations happening every second that needs processing time)
 

Spoiler

Plus the variable factors involved like content type, resolution and bitrate, edits made and effects and transitions used .

 

There are plenty of videos showing minimal improvement to common tasks when encoding with fastest GPUs vs Midrange ones.. #NotAlways but Diminishing returns are a thing for Encodes in Premiere and faster GPUs with or without HW encoding enabled.
