CPU Comparison
Intel Core i5-8269U vs Intel Core i7-8559U
A side-by-side comparison of specs, performance and value. The Intel Core i5-8269U is a quad-core mobile processor from Intel's 8th Generation Coffee Lake-U lineup, designed primarily for premium thin-and-light laptops and Apple's Mac mini. Operating with a base clock of 2.6 GHz and boosting up to 4.2 GHz, it utilizes Intel's 14nm manufacturing process. With 8 threads and 6MB of L3 cache, it delivers robust performance for productivity, multitasking, and moderate creative workloads. Unlike standard U-series processors limited to 15W, the 8269U features a higher 28W TDP, allowing for better sustained performance and integration of the more powerful Iris Plus Graphics 655. This eDRAM-backed GPU provides significantly better graphical capability and video encoding performance than standard UHD graphics. Commonly found in premium ultrabooks and compact desktops, it offers an excellent balance of high clock speeds, capable integrated graphics, and manageable thermal output for users needing more than basic mobile computing power.
