Windows 10 19H2 update to include Favored CPU Core Optimization
Both Intel and AMD invented a methodology that can select the fastest core to be the 'favored core'. However, as with anything, Windows does not recognize that. Basically an application could end up at the slowest core.
That is going to change with a pending 'big' Windows update as Microsoft will be including favored core awareness into the OS, and that can speed up single-threaded applications up-to 15%. For Intel Turbo Boost Max Technology 3.0, an operating system will use information stored in the CPU to identify which cores are the fastest and then prioritize them, Intel, says "delivers more than 15% better single-threaded performance". "A CPU may have multiple “favored” cores (logical processors of the highest available scheduling class). To provide better performance and reliability, we have implemented a rotation policy that distributes work more fairly among these favored cores."
For AMD, Microsoft already included an optimization in the last 1903 update, we're not certain if the 19H2 update will have an actual effect as it already might be supported.

On the mainstream CPUs you can just enable that setting in bios and all the cores will boost to maximum speed

Except, kind of the point is not all cores are equal. Some (especially in the case of AMD) can clock higher than others, even if you haven't overclocked.

Considering their track record lately should we start betting what they will break with this update on the first roll out ? I say they will break the power stager and will get one or more cores stuck to max speed even at idle ! Just guessing here :p

I was curious to find out which actual Intel CPUs would be positively affected by this update. The only CPUs that are applicable are these ones (found on Intel webpage, https://www.intel.co.uk/content/www/uk/en/support/articles/000021587/processors.html), that's because these are the only CPUs that support Intel® Turbo Boost Max Technology 3.0:
Intel® Core™ i7-69xx/68xx Processor Family
Intel® Core™ i9-7900X/i9-7920X/i9-7940X/i9-7960X/i9-7980XE/i7-7820X/i7-9800X
Intel® Core™ i9-9820X/i9-99x0XE/i9-99x0X
Intel® Xeon® Processor E5-1600 v4 Product Family (single-socket only)
