Intel Core Ultra 9 290HX Plus

Buying advice

Intel Core Ultra 9 290HX Plus is best suited to large gaming laptops, creator notebooks, and mobile workstations that prioritize CPU throughput over thin-and-light battery life. Its 24-core Arrow Lake design, high turbo power budget, and strong single- and multi-core positioning make it the better HX Plus choice for compiling, rendering, heavy multitasking, and CPU-bound game workloads. Choose it in chassis with serious cooling; smaller laptops or buyers focused on quieter daily use may be better served by lower HX Plus or non-Plus Core Ultra options.
