Core i7-4558U Details

The Intel Core i7-4558U, launched in June 2013, remains a notable mobile processor from the Haswell generation, offering a blend of efficiency and performance that was competitive in its time. With a 28 W TDP and a 22 nm process node, it was designed for thin and light laptops, prioritizing power efficiency without sacrificing core functionality. Despite being over a decade old, its performance still holds up in certain contexts, particularly in single-threaded workloads. The processor features two physical cores with Hyper-Threading, delivering four threads, and operates at a base frequency of 2.8 GHz, with a turbo boost up to 3.3 GHz, making it capable of handling everyday computing tasks and moderate productivity workloads. It supports DDR3L-1333/1600 memory and integrates Intel HD 5100 graphics, which, while outdated by modern standards, provided sufficient graphical performance for light multimedia and basic office use when launched.

In benchmark testing, the Core i7-4558U achieves an Overall Score of 4951, placing it at #910 out of 2060 CPUs, with a Singlecore Score of 5223 (#794 of 2060) and a Multicore Score of 4544 (#1165 of 2060). These results highlight a processor that is more balanced in single-core performance than in multi-threaded workloads, a reflection of its dual-core design and older architecture. Compared to its immediate peers like the Core i7-4720HQ and Core i5-4460S, the i7-4558U holds its own in single-threaded tasks, though it lags behind in multicore performance, where it is outpaced by more modern and higher-core-count CPUs. Its single-core performance, however, places it above several newer processors such as the Core i7-6567U and Core i5-750, indicating that while it is no longer competitive in raw power, it remains relevant for applications that rely heavily on clock speed and efficiency.

The i7-4558U supports a broad range of Intel technologies, including AVX, AVX2, AES-NI, and Intel vPro, which enhance encryption, virtualization, and data processing capabilities. It also includes Intel Hyper-Threading, allowing the two cores to handle four threads simultaneously, improving multitasking and responsiveness. While the processor’s 3.815 MiB of L3 cache and 4 MiB of total cache are modest by today’s standards, they were adequate for its intended use case. Its integrated Intel HD 5100 graphics support up to three displays and offer basic GPU acceleration, though it lacks the capabilities required for modern gaming or GPU-intensive applications.

As of March 2026, the Core i7-4558U is best suited for legacy systems, low-power laptops, or entry-level devices where power efficiency and basic computing performance are prioritized over cutting-edge capabilities. It remains a viable option for users who need a reliable, low-power CPU for office work, web browsing, and media consumption but do not require high-end performance. While it is overshadowed by today’s top-tier processors—many of which score over 8,000 in overall benchmarks—it still represents a capable mobile CPU for its era, demonstrating Intel’s focus on energy efficiency and integrated graphics in the early 2010s.
