CPU Comparison

Intel Core i5-1035G4 vs Intel Core i5-8265U

A side-by-side comparison of specs, performance and value. The Intel Core i5-1035G4 is a mid-tier mobile processor launched in August 2019 as part of the 10th Gen Ice Lake-U family. Built on Intel's 10nm process, it utilizes the Sunny Cove microarchitecture and features four cores and eight threads, making it well-suited for multitasking and everyday productivity. With a base clock of 1.1 GHz and a max turbo frequency of 3.7 GHz, it offers responsive performance in thin-and-light laptops. The processor operates at a 15-watt TDP, balancing power consumption and thermal output. A defining characteristic of the G4 variant is its inclusion of Intel Iris Plus graphics with 48 execution units, sitting between the lower-end UHD graphics and the higher-end 64-EU Iris Plus. This makes it capable of smooth 4K media playback and casual gaming. With support for LPDDR4 memory and PCIe Gen 3, the i5-1035G4 provides a versatile foundation for portable computing devices requiring a step up in graphical performance.
