CPU Comparison
Intel Core i5-4200U vs Intel Core i7-4558U
A side-by-side comparison of specs, performance and value. The Intel Core i5-4200U is a dual-core, ultra-low voltage mobile processor launched in mid-2013 as part of the 4th Generation Core (Haswell) lineup. With a 15-watt TDP, it became the quintessential processor for the era's Ultrabooks, striking a balance between power efficiency and everyday performance. It features two physical cores and four threads thanks to Intel's Hyper-Threading technology, allowing it to handle multitasking with relative ease. The base clock speed is set at 1.6 GHz, dynamically boosting up to 2.6 GHz via Intel Turbo Boost technology when demanding workloads require extra performance. The processor is equipped with 3 MB of SmartCache and integrates Intel HD Graphics 4400, offering smooth 1080p video playback and the ability to play light casual games. It was a defining chip for mainstream thin-and-light laptops, offering an excellent blend of battery life and productivity performance.

Best for: Extremely cheap used laptop for basic text editing
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.
