    What we like about Intel Core Ultra 7 155UL

    • Exceptional power efficiency and battery life for light productivity and everyday use
    • Improved integrated graphics performance over previous generation Iris Xe, supporting modern features like ray tracing
    • Includes a dedicated NPU (AI Boost) to offload AI tasks from the main CPU cores
    • Ideal for thin and light laptops due to its low 15W base TDP
    • Strong multitasking capabilities for office and school workloads thanks to its 12-core/14-thread architecture

    What we don't like about Intel Core Ultra 7 155UL

    • Significantly lower multi-threaded performance compared to the 'H' series variants (e.g., 155H) due to fewer performance cores
    • Performance can be inconsistent under heavy, sustained loads, often leading to thermal throttling in slim chassis
    • Single-core performance gains over the previous 13th-gen i7 models are relatively minor
    • Smaller L3 cache (12MB) compared to high-end Ultra 7 chips can impact data-intensive tasks
    • Limited gaming capability, restricted to 1080p at low settings for most modern titles

    Verdict

    The Intel Core Ultra 7 155U is a mid-range Meteor Lake-U mobile processor designed for thin-and-light laptops, featuring a 12-core, 14-thread configuration (2 Performance, 8 Efficient, and 2 Low-Power Efficient cores) with a max turbo frequency of 4.8 GHz. Built on a 7nm process, it integrates a 4-core Intel Arc iGPU (up to 1.95 GHz) and a dedicated AI Boost NPU for hardware-accelerated AI tasks. Its main strengths include exceptional power efficiency with a 15W base TDP (up to 57W boost), support for high-speed LPDDR5x-7467 RAM, and modern connectivity like PCIe 4.0 and Thunderbolt 4. However, it is limited by a relatively small 12MB L3 cache compared to the higher-end 'H' series and may exhibit inconsistent performance under sustained heavy multi-threaded workloads due to its lean core distribution.
