The Intel Core Ultra 7 265K is a high-performance desktop processor from Intel’s Arrow Lake series (Core Ultra Series 2), featuring a hybrid architecture with 8 Lion Cove performance cores and 12 Skymont efficient cores for a total of 20 cores and 20 threads. It delivers a base frequency of 3.9 GHz on P-cores (boost to 5.5 GHz) and 3.3 GHz on E-cores (boost to 4.6 GHz), paired with 30 MB Smart Cache and support for DDR5-6400 in dual-channel up to 192 GB (ECC yes). Built on a 3 nm process, it offers excellent efficiency with 125W base TDP (250W max turbo).
This unlocked ‘K’ model is ideal for gaming, content creation, and AI workloads, with integrated Intel Graphics (4 Xe-cores, up to 2.0 GHz) supporting 4 displays via HDMI 2.1/DP 2.1. It includes Intel AI Boost NPU (13 TOPS), total platform up to 33 TOPS. Benchmarks show strong multi-threaded performance (e.g., Cinebench edges 14700K in efficiency) but gaming lags ~8% behind due to no hyper-threading[1][2][3]. PCIe 5.0/4.0 (24 lanes), no cooler included—requires robust cooling.
