Which AMD CPU is best for professional video editing workloads?

Question

My old i7 is basically screaming every time I open Premiere now so I'm finally switching to AMD for a new build. I've got about 600 quid to spend on the processor alone and I need to get this ordered by Friday to meet a deadline for a wedding video.

I looked at the 7950X because those 16 cores seem perfect for 4K exports but then I saw people saying the 7950X3D is the best chip. But isnt that just for gaming? I'm confused if the 3D v-cache actually helps with scrub speeds in the timeline or if it just slows down the clock speeds for actual rendering. Also the new 9950X is out but the benchmarks look kinda weird and inconsistent online so I'm stuck between the older flagship or the new stuff. Should I just stick with the standard 7950X for stability or is there a reason to go with the 9000 series for productivity?

I used the AMD Ryzen 9 7950X 16-Core 4.5GHz for my first big wedding project and it handled 4K exports perfectly without any weird crashes or lag.

Honestly, forget the 3D chips for this!! The AMD Ryzen 9 9950X 16-Core 5.7GHz Turbo is an absolute beast for 4K scrubbing because of those massive clock speeds! You want raw frequency for editing, not gaming cache. The benchmarks look weird because of Windows scheduling, but the AVX-512 performance is fantastic for encoding. Its so much better than the AMD Ryzen 9 7950X 16-core 4.5GHz for heavy workloads!!

To add to the point above: I picked up the AMD Ryzen 9 9950X 16-Core 170W TDP for my studio recently and honestly it wasnt as good as expected. I had some really annoying stability issues with the early BIOS versions that almost made me miss a client delivery. It is a bit of a letdown considering the price premium right now. If youre trying to hit a Friday deadline, here is how I see the options:

AMD Ryzen 9 7950X 16-Core 5.7GHz Boost is the most reliable pick. Its way cheaper now and the performance difference in Premiere is tiny compared to the new stuff.

AMD Ryzen 9 7950X3D 16-Core 128MB L3 Cache is unfortunately not worth it for you. The 3D cache is basically useless for encoding and actually slows down your exports because of the lower clock speeds. I would just grab the standard 7950X and put the extra cash toward a Samsung 990 Pro 2TB NVMe SSD for your cache drive. Having a dedicated scratch disk will help your timeline smoothness more than the CPU upgrade anyway. Hope the wedding edit goes well... those deadlines are no joke!
