Render not utilizing 100% of CPU: quad-core Intel @ 100% vs 12-core AMD @ 40%
So I’ve recently transitioned into a new job where I use my personal system to edit all day long. After pushing it hard each and every day I decided to upgrade the workstation to make life a little faster.
Old specs:
Intel i7 – Quad-core – 4 Ghz; 32 GB RAM; Vega 56 RX
New specs:
AMD Ryzen9 3900x – 12-core – 3.7Ghz; 64GB RAM; GeForce 1080ti
Render and processing times have increased for sure, but I’ve noticed that Adobe Media Encoder is not behaving the way I expected. When I was rendering on the old system AME would utilize nearly 100% of the CPU + 50% of the GPU. When I render similar material on the new system, AME only utilizes around 40% of the CPU + 40% of the GPU.
What gives?! I was looking forward to rendering 12 times faster. Is this not how this works? 40% of a 12-core is only marginally faster than 100% of a 4-core, at least mathematically.
Like I said, render times are faster, but could I have seen the same gain merely by upgrading the GPU and not throwing money at the 12-core chip?
Thoughts appreciated.

You don’t mention what source files are, what your sequence settings are and what you’re encoding to. These are all important parts of this.
12 times faster rendering isn’t normally how upgrades work. You get biggest bang for the buck when upgrading a very basic system. As you go higher, the payoff costs more for less improvement.
However you made some great improvements. I think if you provide more details, we can offer suggestions on your workflow to increase as much as possible.
I’d also check out Adobe Premiere Pro Editors on Facebook. This stuff comes up all the time and some very sharp folks there. Tell Kyle I sent you!
