Core i5-4258U Details

The Intel Core i5-4258U sits just behind the Core i7-720QM in multicore performance, with a score of 4495 compared to its closest competitor's 4496. This narrow gap underscores its position as a mid-tier mobile processor from the Haswell era, designed for thin-and-light laptops where efficiency and integrated graphics play a key role. Released in 2014, the Core i5-4258U is now well over a decade old, reflecting its place in the evolution of mobile computing rather than in today's high-performance landscape.

Built on Intel's 22 nm process and based on the Haswell microarchitecture, the processor features two cores and four threads, enabled by Hyper-Threading. It operates at a base frequency of 2.4 GHz, with a turbo frequency of 2.9 GHz, allowing it to scale under load. The chip is packaged in a 1168-pin FCBGA socket, typical of ultra-mobile designs, and has a modest 28 W TDP, making it suitable for fanless or low-noise systems.

Memory support includes DDR3L 1333/1600 with dual-channel capability, delivering a maximum bandwidth of 25.6 GB/s. The integrated Iris™ Graphics 5100 GPU runs at a base frequency of 200 MHz and can boost to 1.1 GHz, supporting up to three displays. While not powerful by modern standards, this GPU was capable of light gaming and video playback when new, and it remains sufficient for basic multimedia tasks.

The Core i5-4258U supports a range of modern features including AVX2, AES-NI, and Intel vPro, which enhance performance and security. It also includes Intel's Enhanced SpeedStep Technology (EIST) for dynamic power management. Despite its age, it remains a stable and reliable choice for legacy systems or embedded applications where cost and compatibility are priorities.

In benchmarking, the processor achieves a single-core score of 4938, ranking it 978th out of 2060, and a multicore score of 4495, placing it 1235th. The overall score of 4761 positions it at 1053rd overall, trailing higher-end processors from both Intel and AMD. While it holds its own against some older quad-core CPUs, it falls significantly behind current-generation offerings, particularly in multi-threaded workloads.

As of March 2026, the Core i5-4258U is best suited for basic productivity, web browsing, and media consumption in lightweight laptops or as a replacement in older systems. Its strengths lie in low power consumption and integrated graphics, but it is no longer competitive in performance-critical environments such as content creation or gaming.
