8600 (non-k) vs 8700 (non-k) Handbrake Build Advice

I am in the process of rebuilding my video encoding machine and am torn between which CPU to use.

I primarily use MakeMKV to rip blu-ray and take the raw MKV and convert it to a M4V using Handbrake. I am interested in x264 and x265 performance.

Right now, I can get a 8600 for 215 USD and a 8700 for 300 USD. Considering Handbrake is not well optimized for CPU's with more then 6 cores, would Hyper-Threading on the 8700 be worth the extra 85 dollars? Or would the money be better spent on a better cooling solution than the CM 212 I was going to use?

Thanks in advance!

On the contrary, libx264 and libx265 used by Handbrake do take advantage of multiple cores. How many, that depends on the video resolution (vertical) you are encoding.
At 1080P resolution you can fully utilize 20+ cores in X264 and ~10 cores in X265.

In X264 HyperThreading provides ~23% performance boost and in X265 the benefit is around 19%.

It can utilize them, but the workflow does not scale well past 6 cores according to Handbrake's own doc

Would it be worth the extra cost?

Why not just check reviews of the 8600:
https://www.guru3d.com/articles_pages/intel_core_i5_8600_processor_(65w)_review,13.html
https://www.techpowerup.com/reviews/Intel/Core_i5_8600/6.html
They compare it to an 8700K but when not overclocked the all core clocking is the same as a regular 8700:
FPS in encoding 37.75 (8700)/30.7(8600) = 23% faster on the 8700 for x264 (~21% for x265).

Only you can decide if that is worth the price difference.
