I just built a new system and a week later the announcement of the KS came out. Just curious if it will show any noticeable benefit over the K for P3D?

Check this out. It is not a flightsim benchmark, but a general benchmark.

 

I guess more info and benchmarks will come out next week when the KS version is in the stores.

Same web site has a report of someone clocking the KS to 5.2 on all cores and threads no problem.

9900KS is nothing but a highly binned 9900k. Architecture is exactly the same and only difference is slightly raised base and all-core boost clock. You shouldn't see any noticeable difference between the two in P3D, and you could actually lose performance if your CPU cooling is not up to the task of increased TDP. First two cores for both of them are running at 5GHz (boost) anyway.

Now if you are looking at achieving absolute highest clock speeds and benchmark scores then this factory binning will give you an edge by largely eliminating silicon lottery. But if you are just looking for a performance increase then upgrading from 9900K to 9900KS is just a lot of money down the drain.

The same CPU cooling on both you will find the 9900k at 4ghz the same 127W possibly more heat, we will find out soon you my see testers pushing this on AIO to 5.3 to 5.5 stable.

Sure, it somewhat depends on SVID mapping, but there is no fighting the fact that higher amperage is required to maintain higher clock speeds. And anything outside of Intel optimized defaults for boost duration is a balancing act and no concrete results can be drawn without a huge sample rate.
