WIN10 should function well with the Core i9 12900KS if you configure a constant clock speed for both P and E cores.
WIN10 should function well with the Core i9 12900KS if you configure a constant clock speed for both P and E cores.
Now considering my perspective as I revisit Alder Lake 12900KS from AMD, shouldn't WIN10 function properly as long as the e cores and p cores maintain static frequencies? Well, since Intel’s Coffee Lake line and all the way through Rocket Lake have allowed differentiation in clock speeds for various cores, it seems reasonable that WIN10 could adapt. The earlier approach of adjusting clock speeds in BIOS worked well for Intel; AMD has followed a similar path with Zen series. Although core types differ, they were generally lower clocked and thus slower. Still, per the specs, performance golden cores (8) and efficiency Gracemont cores (4-8) share the same IPC on comparable CPUs. However, Gracemont cores are inherently clocked slower unless their frequency is adjusted. If WIN10 could intelligently select faster cores based on clock speed—just like it did in prior generations—it would handle this scenario effectively. Even if e cores have lower IPC than p cores due to architectural differences, they’re still clocked lower, so Windows should recognize that and manage performance accordingly. Assuming the Ultimate Performance Power plan is active, maintaining minimum and maximum CPU usage at 100% makes sense for desktops, unlike laptops. If you're certain this fits your setup, feel free to adjust it; otherwise, it depends on both OS and hardware considerations.
It's more involved than it seems. Windows 11 was primarily designed for Intel hardware, so they inquired about updating Windows 10. They mentioned it would require significant effort, prompting them to ask if a new OS could be developed that would work better together. Windows 11 remains a Beta version—don't let Microsoft mislead you. It should still function on Windows 10, though performance may decrease slightly. If you prefer Windows 10, sticking with it is perfectly fine.
You're asking about how Windows 10 handled CPU core selection. It seems you're wondering if the operating system could automatically choose the best cores for performance, or if users had to rely on software tools like Ryzen Master or CPPC to optimize things. You also mentioned observations about games defaulting to certain cores and whether Windows would adapt based solely on clock speed. It looks like you're curious about the balance between automatic management and manual control in modern operating systems.
To unlock full capabilities from your 12th generation CPU, Windows 11 has proven effective. This is due to the operating system recognizing both P and E cores. Windows 10 falls short in this regard. The interface won’t display a slideshow on Windows 10—it will function normally, and you’ll likely appreciate it if you’re unaware of this detail. In summary, modern operating systems generally work well on PCs, but for optimal speed, Windows 11 is recommended.
Performance benchmarks show better results under Win11 when using models with P and E cores. This isn't just a general rule—it varies based on the specific game, settings, software, and how you use the system.
