CPU Comparison

Intel Core i5-4250U vs Intel Core i5-4350U

A side-by-side comparison of specs, performance and value. The Intel Core i5-4250U is a specialized dual-core mobile processor released in mid-2013 as part of the 4th Generation Core (Haswell) family. While it shares the same 15-watt TDP and dual-core, four-thread configuration as other U-series chips, it distinguishes itself by integrating Intel HD Graphics 5000 instead of the standard HD 4400. This graphics upgrade features 40 execution units, double the amount found in the 4400, making it highly capable of handling graphics-intensive tasks for its form factor. Operating at a base clock of 1.3 GHz with a turbo boost up to 2.6 GHz, it was optimized for systems that required better graphical output without sacrificing battery life. This specific chip was heavily favored by Apple for its 2013 MacBook Air lineup, where its efficient power consumption and enhanced integrated graphics provided an excellent balance of performance and longevity for on-the-go users.
