RTX 3060 12gb low performance in Premiere Pro

[alicja_1140]

Hey guys, 

First of all, I'd like to say im very mixed about what happend with pr.

I just bought new RTX 3060 12gb, amd processor 5600x and 80gb ram.

I do edit clips which are 4k 50fps 10bit and guys, don't get me wrong, but as I upgrade my pc, I'd like to get more performance here.

What I got?

Very bad performance, laggy playback, doesn't matter - full, 1/2, 1/4.

Okay, effects, rendering is much faster, but I cannot edit these files by not doing proxies. It's just making me frustrating, because my guy, who has the same set up, got better performance.

He can work on full, with no problem, but my pc is just dying there.

What I do, so don't give me the same advice twice:

- Clear cache

- Cuda ON
- Cache saving on SSD
- Clips on SSD
- All rams around 67gb is set up for premiere pro

- New drivers are installed

Are you using an NVIDIA Studio driver and not a Game driver?

What size and how full is the SSD?

[alicja_1140]

I do use Studio Driver, not Game driver. I read about that, so im using Studio Driver.

About my SSD - it's 1TB space as defult, and now its about 50% full. Around 400GB's is free

That's an older 6 core CPU with no long-GOP internal ... or any other internal graphics ... capabilities.

Core counts matter these days, and the 24.x series of builds really jumped at expecting many cores available. 25.x continued that ... I would recommend a minimum of 8 cores for a laptop and wouldn't expect rapid processing ...  just the ability to work, if ... slowly. For a desktop, 12 cores or better is really a good idea.

And if you do any long-GOP H.264/5 media, having a CPU with internal "hardware" processing is best ... and finally, some new AMD chips do have that. Your only possibility for that as "hardware" mode is the GPU.

So ... there are some issues with that rig, that you just need to think smart about how you set your projects up to get around them.

What you recommend to do? Change cpu for something with more cores? What I saw, i can replace my current cpu to ryzen 9 5950x with 16 cores?

[R Neil Haugen]

That's a bit newer than my 3960x, which is actually still performing very well with both Premiere 25.x and Resolve 19, AfterEffects and on.

Understand, I don't do much long-GOP, the H.264/5 stuff. Had I done a lot of that, I would have gotten a rig with an Intel CPU inside.

So for non-long-GOP media, that CPU would be a lot faster than your current rig. Probably even better with the long-GOP because it processes so much faster. If you can get one cheaply enough, probably a decent upgrade for now.

If you need long-GOP, not what I'd do though.

@RjL190365 would be the person with the most information.

Part of your problem is the memory configuration. You see, 80 GB absolutely requires mixed, mismatched DIMMs to begin with. You are mixing completely different memory ICs with completely different chip densities in the same PC, which will severely degrade overall system performance, especially in CPU-intensive tasks. In this case, your system's memory speed may have defaulted to a fail-safe, very slow memory speed of only DDR4-2133, which Zen 3 CPUs are highly sensitive to. And depending on where you installed the mismatched pairs of DIMMs are installed, your CPU's memory controller may have defaulted to the single-channel-only mode, which will degrade system performance even further.

And that's on top of the fact that Nvida's NVDEC hardware decoder just doesn't perform well on H.264. It is deficient to the point where even my main PC's Intel i9-14900K is faster in decoding H.264 in software-only mode than any Nvidia GPU up to and including the RTX 4090 is in hardware mode.
