@fabio how are the ‘auto’ turbo limits impacting performance? I saw on your blender screen cap that the 9900k dropped to 4.7, but hit 5ghz earlier in the test (which also drew more power as the maximum is higher than the current on the screenshot). I’ve never run a Blender test so I don’t know if that’s expected (or it’s just an AVX workload), but is it possible the motherboard is power limiting the cpu at times (possibly having a different impact on the 9900k vs the 8700k)?
