Core i7-5550U Details

The Intel Core i7-5550U stands out for its strong single-core performance, achieving a score of 5139 in the Singlecore Score benchmark, ranking it #858 among 2060 processors. This performance is particularly notable given the processor's age—launched in March 2015—and its 15 W TDP, making it a capable mobile solution for its time. While its multicore score of 4605 places it at #1082, the gap between single-core and multicore rankings highlights its relative strength in thread-intensive workloads compared to modern multi-core processors. As of March 2026, the i7-5550U remains a viable option for lightweight productivity and occasional multimedia tasks, though it falls far behind contemporary desktop and mobile CPUs in raw processing power.

Built on Intel's 14 nm Broadwell-U architecture, the Core i7-5550U is designed for mobile systems, featuring a compact FC-BGA1168 package. It includes two physical cores with Hyper-Threading, enabling four threads, and operates at a base frequency of 2.0 GHz, capable of boosting up to 3.0 GHz under load. The processor integrates Intel HD Graphics 6000, a GPU with a maximum frequency of 1.0 GHz, supporting up to three displays and offering basic graphics performance suitable for office applications and light video playback. With 4 MB of L3 cache, 0.061 MiB of L1, and 0.244 MiB of L2 cache, it balances performance and efficiency, though its dual-channel DDR3L/LPDDR3 memory support limits bandwidth compared to modern standards.

Despite its age, the i7-5550U supports a range of modern features, including AVX2, AES-NI, and Intel's virtualization technologies like VT-x and VT-d, making it suitable for virtual machines and secure computing environments. It also includes Intel's Enhanced SpeedStep (EIST) for power efficiency and is compatible with Intel vPro for enterprise management. However, its 14 nm process and lack of support for newer memory types like DDR4 or DDR5 constrain its competitiveness in today’s market. While it holds its own against older CPUs such as the Core i7-4600M and Core i7-4870HQ in multicore performance, it is outpaced by newer mobile processors like the Ryzen 5 3500U and Core i5-7440HQ.

In benchmark terms, the i7-5550U achieves an overall score of 4925, placing it at #927 among 2060 processors. Its performance is comparable to mid-range mobile chips from the mid-2010s but is significantly surpassed by modern high-end processors, such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which exceed 9000 in overall scores. The processor's standout strength lies in its single-core performance, where it ranks ahead of many modern CPUs with lower base frequencies, such as the Core i5-6500T and Core i3-1000NG4. However, its multicore and memory bandwidth limitations make it less suitable for demanding applications like video editing or gaming.

Overall, the Core i7-5550U remains a relic of its era—efficient, compact, and capable of handling basic computing tasks with minimal power draw. It is best suited for users seeking a reliable, low-power mobile processor for general use, such as web browsing, document editing, and media consumption. While it cannot compete with today’s high-performance CPUs, its longevity and stability continue to make it a functional choice in older systems or budget-friendly laptops.
