Intel Core Ultra 5 245KF 14-core LGA1851
The Arrow Lake architecture on 3nm delivers strong single-core speeds up to 5.2GHz and a 43,112 PassMark score, making it a capable performer for demanding desktop tasks. Its unlocked multiplier and 125W base power provide headroom for overclocking, while the lack of integrated graphics keeps the platform cost focused purely on CPU performance. This processor is best for budget-conscious productivity builders who pair it with a discrete GPU for rendering, code compilation, or heavy multitasking.
