I bit the bullet and upgraded my processor i7-8700K to i9-9900K (new stepping R0) on my good old Z370 mobo (that is possible if flash your BIOS for i9, and additionally also for stepping R0). I could not find any info on what Intel has changed (improved?) on i9900K stepping P0 to Stepping R0. Anyone knows? You can recognize stepping R0 on the processor housing as "SRG19".

According to the information I found about the R0 stepping is it a (family) security update with a new die but no performance increase to the P0 stepping.

What I did see is a big improvement on the average FPS in region 1, this went up from around average 12 to around average 20.

This is quite a lot more than I expected.

I still also consider upgrading my i7-8700k system but only for significant performance increase. Vp17 B321 is still quite slow in loading all thumbs in the timeline. A 35 minutes project with ~500 XAVC-S UHDp30 clips from SSD takes on my i7-8700k system 2min32s. So if this could be reduced significantly, I would take the i9-9900k R0 next.
