Intel Confirms APO Feature Not Coming to 13th Gen and 12th Gen Core Processors
Intel Application Performance Optimization (APO) is a unique feature that sets 14th Gen Core "Raptor Lake Refresh" processors apart from 13th Gen "Raptor Lake," despite the two being practically the same microarchitecture. APO is software-based, application-specific processor optimization that is found to offer an up to 16% performance boost in "Metro Exodus," and an up to 13% boost in "Rainbow Six: Siege." These are the only two games that Intel has released APO optimizations for, and for now, APO is only supported on the Core i9-14900K and i9-14900KF. Hardware Unboxed learned that while the company might bring APO to more 14th Gen Core processor models in the near future; it won't make it to 13th Gen Core "Raptor Lake" and older 12th Gen Core "Alder Lake."
APO is an extension of Intel Dynamic Tuning Technology framework that provides a greater degree of handholding for the OS scheduler, to give a specific application the best possible allocation of hardware system resources. For Intel to release APO profiles to new games, it needs extensive testing and validation specific to processor models and the applications themselves, which is probably why the company is limiting APO to only its current 14th Gen processors, and only specific processor models within the lineup. You can catch the Hardware Unboxed presentation with their testing of APO on the two supported titles, and Intel's statement, in the source link below.

It should have just been pitched as a tech demo until it had broader hardware and software support.
/sIt has nothing to do with Ecores, people need to stop this misinformation. Every CPU ecores or no ecores would perform better with proper game specific scheduling. Especially the dual ccd zens
That's why the first thing I did on my 14900k was to turn off HT. Dropped power draw by a crapton
In Mt workloads, went from 41k to 37k in cbr23 but with a huge drop in power and temperatures.
User himself can test if his settings have some negative impact and if this impact is worth it compared to what is he trying to do with these settings (as lowering power draw by changing frequencies, disabling some e-cores, etc.).
CPU hits around 380w on stock and then thermal throttles down to around 320 that my cooler can handle. With ht off and a lower llc (since it doesn't need that much voltage with HT off) power draw stats at a constant 200 to 220 watts.
The only good source of information is the Linux kernel, but it aims for completely different goals. Well, probably. We can't know.
Meanwhile nobody releases a server processor with very mixed cores yet. Might have a reason.
