The Intel Core Ultra 7 265KF is a high-performance desktop processor from Intel’s Arrow Lake series (Core Ultra Series 2), launched in Q4 2024. Featuring 20 cores (8 Performance Lion Cove + 12 Efficient Skymont) and 20 threads, it delivers strong single- and multi-threaded performance for gaming, content creation, and AI workloads. Base clocks are 3.9GHz on P-cores and 3.3GHz on E-cores, boosting to 5.5GHz and 4.6GHz respectively. With 30MB Smart Cache (L3) and 36MB L2, it excels in cache-sensitive tasks.
This F-series CPU has no integrated graphics, requiring a discrete GPU, and uses the new LGA1851 socket. It supports DDR5-6400 dual-channel memory up to 192GB, PCIe 5.0/4.0 (24 lanes), and Intel AI Boost NPU (up to 13 TOPs total 25 TOPs). TDP is 125W base / 250W turbo, with max temp 105°C. The ‘KF’ suffix indicates it’s unlocked for overclocking. Ships boxed without cooler.
