Intel have gone a bit mad and paired 8 'performance' cores with 8 'efficient' ones. The former have hyperthreading and are faster than anything else. The latter have no HT and are apparently around skylake performance.
To make the most of this the OS needs to know which cores should be doing what. Windows 10 can't do that, but 11 has a new task scheduler specifically for it.

That's one way of looking at it. For mixed office use where an "efficient" core is more than enough for most of the day, the 12th Gen hybrid probably cuts your power and AC bills enough to justify it's existence. If you want all the power all the time for demanding workstation loads, there's always Xeon
The new Intel? Haven't read about it yet but presume fewer cores but faster ones? Again, varies by NLE but more cores seems to get better results than fewer faster ones on Resolve.
