Are there other options to enhance performance beyond PBO to approach 10700 outcomes?
Consider a 5800X or even a 5600X if you're correct about its optimization for just four cores. You're achieving over 4.4Ghz stability on three cores and around 3.9Ghz on others. Even with a fixed overclock stable at roughly 4.3Ghz across all cores, it won't improve the performance of threads that only operated at 2.2-2.8Ghz in your report—especially not the 3.9Ghz ones, which likely weren't active at all. This is why they're running so slowly. It will merely reduce the speed of those cores operating above 4.4Ghz and handling the workload. Another approach would be to investigate who designed your compression software and explore options for it to function efficiently on an 8-core/16-thread AMD CPU.

First use TB to read the specs on the ram. After opening DC, there's an easy export that'll plug all the values in for you. That'll give the best settings for the ram speeds. There's even a video tutorial on certain setups, advised to watch it. Once manually plugged into bios, I'd advise saving as a User profile so if you ever need to reset bios, just load the profile to return ram to tailored settings.
ClockTuner2 is all about lowering voltages to maximize boosts. Ryzens boost according to voltage, temp and loads. If you max any of those 3, the Ryzen will start cutting back on MHz on a core by core basis. So if you can minimize those, you get higher stable boosts. It does have some default settings, but those are adjustable, you can set VID and Hz and let the program run, it'll test stability per CCX to get the best your cpu can do.
Even has 3 different settings based on workload that can automatically run, mine is set stock for light loads, high for medium loads and slightly lower for full core use. So I get 4.2-4.4GHz across any used core, and temps don't exceed 62°C @ 1.215v vs stock 1.475v all core and 85°C at 3.9GHz..

Ryzens perform best when left to perform as a Ryzen. A standard Intel 'push it hard at this setting' OC by maximizing clocks then dropping voltages will work just fine, as long as you are prepared for the constant high heat as a result.
Cinebench R20 got my 3700x at stock @ 3723. A full 4.4GHz OC got 5101 @ 85°C. CT2+DC got 5000 @ 62°C. To me, the 1300 point bonus performance from CT2+DC far outweighs the extra 100 points and 20°C gain from the OC.
Oh, and because it's a Ryzen, the manual OC actually had 30 point lower single core score vrs the CT2+DC score, which can be important in gaming as single core performance is often the basis for fps.
Another detail I overlooked....
You might consider per-CCX overclocking. A 3800X is constructed from a single CCD chiplet paired with two four-core CCX units. Many motherboard BIOS versions permit overclocking individual CCXs (or CCDs for the 3900X and 3950X models). The goal is to identify which of your eight cores are the most powerful and where most of them reside. Then, focus on overclocking just that particular CCX until it consistently reaches above 4.25Ghz—since it already does so. I’d aim for around 4.5Ghz at least.
The concept is that your compression utility isn’t handling much intensive processing for the other threads, likely just basic maintenance tasks, which shouldn’t hinder the main threads. Therefore, you should clock the remaining CCXs at a very low frequency—perhaps 3.9Ghz or even 3.4Ghz. This approach keeps the entire CPU cooler because only the strongest cores will be running at a high speed. The aim is to potentially reach a stable overclock of 4.5–4.6Ghz at a reasonable voltage, ensuring stability and efficiency for continuous compression.
You’ll need to ensure that the compression threads operate on the high-performing cores while the slower ones handle routine tasks. I’m not very familiar with Linux, but I think it has thread affinity tools that could help. Or perhaps the Linux scheduler is capable of managing this automatically; I doubt Windows would be as precise.
