CPU Comparison
Intel Core i5-4210U vs Intel Core i7-4558U
A side-by-side comparison of specs, performance and value. The Intel Core i5-4210U is a dual-core mobile processor launched in early 2014 as a minor refresh within the 4th Generation Core (Haswell) family. Designed for thin-and-light laptops and Ultrabooks, it operates on a 15-watt thermal envelope, offering a balance of battery life and everyday productivity performance. It features two physical cores and four threads, utilizing Hyper-Threading to improve multitasking efficiency. The processor has a base clock of 1.7 GHz and can dynamically boost up to 2.7 GHz using Intel Turbo Boost technology, providing extra headroom for bursty workloads. It includes 3 MB of L3 cache and integrates Intel HD Graphics 4400, which is capable of handling 1080p media playback and basic graphics tasks. This refresh offered a marginal clock speed bump over the i5-4200U, aiming to keep the Haswell lineup competitive in the mobile market until the arrival of Broadwell.

Best for: Free or extremely cheap used laptop
Read the full reviewA premium 28W mobile CPU that combined high clock speeds with Iris graphics, delivering an excellent balance of CPU and GPU performance for 2013.
Best for: If you are considering a laptop with the Intel Core i7-4558U, you are likely looking at a used MacBook Pro or a premium ultrabook. This processor remains capable for everyday productivity, programming, and light 1080p video editing. The inclusion of Iris 5100 graphics provides a noticeable boost in graphical tasks compared to standard U-series chips. It is an excellent choice for users who need a compact, moderately powerful machine without paying the premium for modern hardware. However, be aware that it is an older Intel-based Mac, meaning it will eventually lose macOS support. Avoid this processor if you need to run modern AAA games or heavy 3D rendering workloads. It is best purchased at a discount for general use.
