You know, I never tried a non-hyperthreaded processor. I think I can use Quick Sync on Premiere if I also get the TMPGEnc plugin, I will try it out and see how the quality is.
That Intel chip looks juicy, but I would need a new MB as well.

i5-8400 Benchmarks and Comparison

@DrDave

results look more like preview material

What you mean?

@DrDave

I think this comparison and whole talks are useless.

As they are for low bitrate modes and encoding of video games (it is fast jerky motion most of the time).

Power of hardware encoder is if you use good bitrates and normal videos (especially like your concerts that are mostly still). With normal bitrate difference with x264 will be really small.

Core i5-8600K review

Intel actually can't cope with cooling processor with Turbo mode.

Intel actually ask Z370 board manufacturers to make Turbo mode more light (but they do not want to do it, as benchmarks will get up to 10% penalties)

Check below recommended mode (frequency and VCore drop)

So almost all preliminary benchmarks had been artificially inflated 4-10%.
