CPU Comparison
Intel Core Ultra 5 125U vs Intel Core Ultra 5 134U
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 125U is a power-efficient mobile processor launched in December 2023 under the Meteor Lake architecture. Designed specifically for thin-and-light laptops where battery longevity is the primary concern, it operates at a low base TDP of 15W. The processor features a 12-core hybrid layout, comprising 2 P-cores, 8 E-cores, and 2 Low-Power E-cores (LP E-cores), resulting in 14 processing threads. Its base clock of 1.3 GHz is deliberately conservative, but it can dynamically boost up to 4.3 GHz when demanding tasks arise. Built using a combination of Intel’s 7nm process for the compute tile and TSMC’s nodes for the SOC and graphics tiles, it offers a balanced efficiency profile. The integrated Arc Xe-LPG graphics with 64 Execution Units handle everyday visual workloads, while an 11 TOPS NPU provides basic AI acceleration. This chip is tailored for everyday productivity, web browsing, and media consumption rather than heavy content creation.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday office tasks and multitasking smoothly without overheating.
Adequate for basic office tasks, but will slow down under heavy multitasking or large file processing.
Gaming
Only suitable for very light or older games. Not recommended for modern AAA gaming.
Not suitable for modern gaming. Can handle 2D indie games and very old titles.
Virtualization
Can run basic VMs, but the 2 P-cores limit heavy virtualization performance.
Not recommended for virtualization due to the 9W power limit and low base clocks.
Efficiency
Excellent efficiency with a 15W TDP, ensuring long battery life for ultraportables.
Industry-leading efficiency. Can achieve multiple days of battery life in tablet form factors.
