Core i7-5557U Details

The Intel Core i7-5557U stands out for its single-core performance, achieving a score of 5384 in the Singlecore Score benchmark, placing it at #659 among 2060 processors. While this score is impressive for a mobile processor from 2015, it reflects the era's focus on efficiency and power conservation rather than raw computational throughput. As of March 2026, the Core i7-5557U is a four-year-old mobile CPU, and its performance, though still relevant for basic productivity, is far behind modern processors. It is built on Intel's Broadwell-U architecture, fabricated on a 14 nm process, and features a 2.5 GHz base clock with a turbo frequency of 3.4 GHz. The processor supports Hyper-Threading, enabling it to handle four threads simultaneously, which helps maintain responsiveness in multitasking environments.

The Core i7-5557U is designed for mobile devices, operating within a 28 W TDP and using the FC-BGA1168 socket. It supports dual-channel DDR3L and LPDDR3 memory with a maximum speed of 1866 MT/s, delivering a memory bandwidth of up to 29.9 GB/s. The integrated Intel Iris 6100 graphics engine, with a base frequency of 300 MHz and a burst frequency of 1100 MHz, provides adequate performance for light gaming and multimedia tasks. It supports up to three displays and includes hardware virtualization features such as VT-x and VT-d, making it suitable for virtual machine environments.

In multicore performance, the Core i7-5557U scores 4602, ranking #1085 in the multicore benchmark, indicating that while it remains capable for basic multitasking, its performance is no longer competitive in demanding workloads. The processor's overall score of 5071 places it at #816 in the overall ranking, highlighting its balanced but outdated design. Compared to modern CPUs, it lags significantly behind the top-tier processors, such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which dominate the top 50 lists in all categories.

Despite its age, the Core i7-5557U remains a viable option for users who prioritize power efficiency and integrated graphics in lightweight laptops. Its support for advanced features like AVX2, AES-NI, and Intel's vPro technology ensures compatibility with a wide range of software and security tools. However, for users requiring high-performance computing, content creation, or gaming, newer processors offer vastly superior performance and architectural advancements. The Core i7-5557U serves best as a cost-effective solution for everyday computing, particularly in devices where battery life and thermal efficiency are paramount.
