Gaming

Intel Core i9-12900KFExcellent at 1440p+, Good at 4K
  • Strong single-threaded performance and high P-core clocks enable high FPS in CPU-heavy games.
  • E-cores help with background tasks like streaming and Discord, reducing stalls.
  • Newer architectures (Raptor Lake, Zen 4) often equal or beat it while running cooler.
  • Performance is sensitive to memory speed and power limits; tuned DDR5 and PL1/PL2 adjustments can shift results noticeably.
