The Intel Core Ultra 5 125U is a mobile (laptop) processor with 12 cores (2 Performance-cores and 10 Efficiency-cores), released in 2023. It is part of the Core Ultra 5 lineup, using the Core Ultra Series 1 platform, and uses the FCBGA2049 package, which is soldered to the laptop's motherboard rather than socketed. Internally, it is built on the "Meteor Lake-U" architecture. Only the 2 P-cores support Hyper-Threading, while the 10 E-cores handle a single thread each, together yielding 14 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 5 125U has a base clock of 1.3 GHz and can boost up to 4.3 GHz depending on workload and thermal headroom. Intel manufactures the "Meteor Lake-U" silicon on a Intel 4 process node. This processor supports DDR5/LPDDR5X memory. With a base TDP of 15W and a minimum assured power 12W, maximum turbo power 57W, which the laptop maker sets to suit its cooling design, the Core Ultra 5 125U is an ultra-low-power design aimed at thin-and-light laptops. Integrated graphics are provided by the Graphics solution, so a discrete GPU is not required for display output. The cache hierarchy includes 12MB of L3 cache.
