Best Intel CPU for 4K video editing in 2024?

Question

So I've been looking at upgrading my rig because my current setup is basically choking on 4K h.265 footage from my Sony A7SIII. I did some digging and everyone keeps pointing towards the 14th gen i7 or i9 because of Intel Quicksync. I was leaning towards the i9-14900K because, well, more cores is better for rendering right? But then I saw a bunch of benchmarks saying the i7-14700K is actually like 95% of the performance for way less money and it doesn't turn your room into a literal sauna.

My logic was that if I'm spending 20 hours a week in Premiere Pro for this documentary project I have due in October, I should just get the best. But I only have about 450 to 500 bucks max to spend on the CPU alone since I need to save some cash for more RAM too. I read that the i9 can be super unstable if you dont have a massive cooling setup which kinda scares me because I'm not exactly an expert at tuning bios settings.

Is the i9 actually worth the extra heat and price jump for 10-bit 4:2:2 scrubbing or would I be totally fine with the i7? Im also seeing stuff about the newer Ultra chips but honestly the naming is so confusing now I dont even know if they're out or if they're better for desktop stuff...

Building on the earlier suggestion, i agree the i7 is safer for stability. dont risk it, make sure to:Get Intel Core i7-14700K 20-Core ProcessorUse Noctua NH-D15 Air Cooler

I've tried many setups, but in my experience, stability beats raw speed every single time. I tried pushing an Intel Core i9-14900K 24-Core Processor last year, but the thermal throttling and voltage scares just werent worth it for a deadline, imo. Honestly, I found the Intel Core i7-13700K 16-Core Processor way more predictable under heavy Premiere loads... sometimes chasing the newest stuff just leads to more downtime.

Honestly, I grabbed that i9 and it was such a letdown. Unfortunately the thermal throttling is just insane, basically a space heater in my studio. I think you are way better off with the i7. IIRC it handles 10-bit scrubbing just as well without the stability drama. Not sure if those new Ultra chips are actually better yet, but the i9 is just a massive headache.
