Intel Core Ultra 265K 20-core LGA1851
The Arrow Lake-S architecture on 3nm delivers a 5.5 GHz boost across 20 cores with a 125W TDP, enabling cooler, quieter operation without sacrificing its 58,722 PassMark multi-core throughput. Its unlocked multiplier and support for 256GB of DDR5 ECC memory on the new LGA1851 socket provide a flexible, future-proof foundation for DIY builds. This processor is best for productivity users and AI/LLM experimenters who need high multi-threaded efficiency and modern connectivity, rather than pure gaming performance.
