The Intel Core Ultra 7 251HX is a mobile (laptop) processor with 18 cores (6 Performance-cores and 12 Efficiency-cores), released in 2026. It is part of the Core Ultra 7 lineup, using the Core Ultra Series 2 platform, and uses the FCBGA2114 package, which is soldered to the laptop's motherboard rather than socketed. Internally, it is built on the "Arrow Lake-HX Refresh" architecture. Only the 6 P-cores support Hyper-Threading, while the 12 E-cores handle a single thread each, together yielding 18 threads: the P-cores tackle latency-sensitive and lightly-threaded work, while the E-cores take on background and highly parallel tasks. The Core Ultra 7 251HX has a base clock of 2.9 GHz and can boost up to 5.1 GHz depending on workload and thermal headroom. Intel manufactures the "Arrow Lake-HX Refresh" silicon on a TSMC N3B process node. This processor supports DDR5/LPDDR5X memory. With a base TDP of 55W and a minimum assured power 45W, maximum turbo power 160W, which the laptop maker sets to suit its cooling design, the Core Ultra 7 251HX is a higher power envelope aimed at performance, gaming and workstation laptops. Integrated graphics are provided by the Graphics solution, so a discrete GPU is not required for display output. The cache hierarchy includes 30MB of L3 cache.
