24-core high-performance mobile processor used in flagship gaming and workstation laptops. It delivers desktop-like performance in large notebook designs.

With 24 cores and 32 threads, the Core i9-14900HX is designed for high-performance flagship gaming and workstation laptops.
A 2.2 GHz base clock and up to 5.8 GHz max boost clock support demanding laptop workloads in large notebook designs.
The processor supports DDR5-5600 or DDR4-3200 memory, PCI Express 5.0 and 4.0, integrated graphics, and overclocking.
The Intel Core i9-14900HX is a 24-core, 32-thread mobile processor for flagship gaming and workstation laptops, featuring up to 5.8 GHz boost speed, integrated graphics, and support for DDR5-5600 or DDR4-3200 memory.
The reviewer describes the processor as ferocious but notes it is very similar to the previous generation, concluding that owners of 13th-gen Core HX laptops should not upgrade, while it remains a compelling option for those with older hardware.
The review highlights the chip as one of the fastest mobile processors for gaming and raw compute, while cautioning that it is power-hungry and highly dependent on laptop cooling and power limits, offering only modest performance gains over its predecessor.
The analysis of leaked benchmarks indicates that while the processor performs well, it offers only minor performance improvements compared to the Core i9-13900HX.
The analysis finds that the processor delivers improved single-core performance due to higher turbo clocks, though architectural changes are minimal, and it faces stiff competition from other high-end mobile chips.
