CPU Choice for Video AI

Be building a new workstation looking at either an i9-13900K or a Ryzen 7950X anyone know if one performs significantly better in Video AI? Most the other software I use (Premier Pro, TMPGEnc Video Mastering Works 7) they seem to be about even give or take.

Thanks!

Hi Josh,

Almost all tasks in Video AI run on the system’s GPU, so either of these CPUs will not be a bottleneck for processing speeds in the app. Which graphics card do you plan to use in this system?

Nvidia RTX 4080.

Good choice, you should see great performance in Video AI.

The only tasks that would run on the CPU are file exports to codecs other than H.264, H.265, and AV1. Those three will make use of the NVENC encoder on the 4080 for hardware acceleration.

Thanks! I usually export to Pro Res it gets it to a nice 4:4:4 10 Bit color then pull into premier make an edits etc, and then off to TMPEG to encode then off to DVD Lab Pro2 to make the DVD Master.

if you running your TVAI process on your GPU, I don’t think either matters.

Yep seems like it, wanted to ask incase it was gonna make an impact, thank you!

You can check the benchmark here :grinning:

Here are the benchmark you might found interesting. :partying_face:

CPU clock speed and RAM speed does make a big difference in processing speed. TVAI use lots of CPU processing power even exporting with NVENC encoder. Espeically, when you are processing with Proteus Auto / Iris Auto.

I also noticed that a powerful CPU makes a difference. If you lower the performance of your CPU for example by turning of Intel Turbo Boost the processing fps noticeably decrease!

In my personal opinion, if you use Premiere Pro, I would choose the i9-13900K over the Ryzen 7950X, because it support iGPU + discrete GPU working at the same time.

Here is the benchmark from PCWorld

Here is the benchmark from Tech Notice

*Note: GN and HUB disable iGPU during their benchmark, that is why GN and HUB benchmark may not represent the real world situation for creators.

Thanks for the graphs and data. Yeah that has me leaning to the 13900k, then TMPEG Masterworks 7 uses AVX-512 which the i9 lacks and that boosts that one. I’m like ughhh >.<

Then add to that being without a PC at the moment is adding frustration, appreciate the info tyvm!

Thank you for that info, it does really look like they are super close in performance. I think it’s gonna end up with what i can find a better deal on.

Much appreciated, thank you!

Cooling! Not too off topic I hope. I’m looking to an i9-13900K for my next upgrade. But don’t want the complexity of water cooling if I can avoid it. Anyone successfully running an i9-13900K flat out (though not overclocking) with an air cooler like e.g. the big Noctuas? I’ve read the ads, but would like to hear from someone who has managed it without melting the CPU!

I am looking at a 360mm AIO for either, specifically the The DeepCool LT720 its really good performance and not dripping in RGB.

I feel with you. 1st of June I ordered my 13900K PC with a 4090. The GPU died after one day. I returned the machine and after almost two months after my order still wait for it. Can’t use Video AI with my laptop and an Rx Vega 8 tough. :frowning:

I fitted the giant NH-D15 Noctua air cooler to my 13900K. But yes, the CPU runs hot. Running the cooler at 600 rpm (can go up to 1500 rpm) the temperature during Video AI processing bounce between 85 °C and 95 °C with peaks to 100 °C. When the PC returns from repair tomorrow I will limit either the max. temperature to maybe 80 °C or 85 °C and/or lower the power target for long and short time duration. That should help! Also the performance loss by lowering the power target is almost negligible!

My apartment got broken into and they stole a ton of stuff including my PC. So i got the renter’s insurance check on Monday. So ordering everything today after work.

Don’t forget the i9-13900K is designed to keep drawing more nd more power until it hits 100c and will stay there. It is designed to run at the absolute limit of your cooling.

Yes, I noticed even tough I was only able to run it for one day before the gpu died. Even then I think I can lower the maximum temperature via some bios settings!

If you look it will default power on PL1 and PL2 to Unlimited (Some BIOS might show it as a huge number like 4096 Wats) if you set those to something within the limits of your cooling like say 250W then you can reel it in. You will lose some performance however.
