CPU Comparison
Intel Core Ultra 5 125H vs Intel Core Ultra 5 125U
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 125H is a highly versatile mobile processor introduced in December 2023 as part of the inaugural Meteor Lake lineup. Designed to bridge the gap between performance and efficiency, it features a unique 14-core hybrid architecture. This includes 4 P-cores, 8 E-cores, and 2 Low-Power E-cores (LP E-cores), totaling 18 processing threads. Operating at a base frequency of 3.6 GHz and boosting up to 4.5 GHz, it provides robust computational power for thin-and-light laptops. The processor is built on Intel's 7nm process for the compute tile, supplemented by TSMC N6 and N5 nodes for the SOC and graphics tiles. It introduces an integrated NPU delivering 11 TOPS, marking Intel’s first major step into AI acceleration on mobile platforms. With a 28W base TDP and a maximum power draw of 115W, the 125H balances aggressive burst performance with the thermal constraints of premium ultraportables, making it a well-rounded chip for creators and professionals.
