Intel Core Ultra 5 125H Review
Intel Core Ultra 5 125H 14-core 18-thread laptop processor, 3.6GHz base / 5.1GHz boost, 28W TDP, Meteor Lake, BGA 2049 (BGA, soldered) socket
The Intel Core Ultra 5 125H is the lower-clocked half of Intel's original Meteor Lake H-series pair, a performance mobile chip for premium laptops built where the 135H isn't needed. Built on Intel's Meteor Lake architecture, it pairs 14 cores and 18 threads with a 3.6GHz base clock that boosts up to 4.5GHz, an on-die NPU rated at 11 TOPS (NPU 3), and Intel Arc Graphics (Xe-LPG) graphics, all within a 28W envelope.
Performance and Architecture
With 14 cores and 18 threads, the Intel Core Ultra 5 125H is built on Intel's Meteor Lake generation. Its 3.6GHz base clock boosts to 5.1GHz, and its Intel Arc Graphics (Xe-LPG) integrated graphics and 11 TOPS (NPU 3) NPU support on-device AI features alongside everyday computing and light content creation.
Platform and Efficiency
The Intel Core Ultra 5 125H uses the BGA 2049 (BGA, soldered) platform in a 28W envelope, positioning it as premium laptops. Its NPU brings Copilot+ style on-device AI acceleration to supported workloads.
Comparison to Alternatives
Within the Core Ultra lineup in this catalog, the Intel Core Ultra 5 125H is the entry point into the H-series pair, priced below the Core Ultra 5 135H while sharing the same core and thread count. Against AMD's Ryzen AI Mobile processors in this catalog, it competes on NPU throughput and platform efficiency, and it undercuts the 135H on price for buyers who don't need the extra clock headroom.
