20-core desktop CPU with 8 performance and 12 efficient cores, 30 MB L3 cache and DDR5-6400 support up to 256 GB, no integrated graphics
Options Core Ultra 7 265KF
The Intel Core Ultra 7 265KF is a desktop processor built on the Arrow Lake architecture using TSMC N3B 3nm manufacturing technology. It fits the LGA 1851 socket and delivers 20 cores comprising 8 performance cores and 12 efficient cores with 20 threads. Base frequencies sit at 3.9 GHz for P-cores and 3.3 GHz for E-cores while maximum turbo reaches 5.5 GHz via Intel Turbo Boost Max Technology 3.0. The chip carries 36 MB L2 cache and 30 MB L3 cache with a 125 W base power rating and no integrated graphics.
This processor suits builders targeting high single-thread speed and strong multi-core throughput for content creation, compilation or gaming at high refresh rates. The lack of integrated graphics means a discrete GPU is mandatory so systems without a dedicated graphics card should look elsewhere. Users needing more than 256 GB of memory or multi-socket scaling will also need a different platform. Overclocking headroom is present but demands robust cooling and a compatible motherboard.
The LGA 1851 socket and 125 W base power are the critical compatibility gates. Only motherboards with the LGA 1851 socket and a power delivery system rated for at least 125 W base power can support this CPU. DDR5 memory up to 6400 MT/s across two channels with a maximum capacity of 256 GB completes the platform requirements. Verify your board and cooler meet these figures before purchase.

이 모델의 다른 버전
같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
Open Task Manager or a monitoring utility such as HWiNFO and run a single-threaded load; the performance cores should report a peak of 5.5 GHz when thermal and power headroom allow.
The boxed processor ships without a thermal solution, so you need a compatible LGA 1851 cooler, plus DDR5 modules rated for up to 6400 MT/s to match the dual-channel controller.
The 265KF delivers 20 cores (8P+12E), 30 MB L3 cache, 125 W base power and no integrated graphics, positioning it as the highest-clocked K-series SKU without an iGPU.
