CPU Comparison
Intel Core i5-1155G7 vs Intel Core i5-1240P
A side-by-side comparison of specs, performance and value. The Intel Core i5-1155G7 is a mid-cycle refresh of the 11th Gen Tiger Lake-U mobile processor lineup, released in May 2021. Built on the 10nm SuperFin process with Willow Cove architecture, it features 4 cores and 8 threads, operating at a base clock of 2.5 GHz and boosting up to 4.5 GHz. This refresh offered a slight frequency bump over the original i5-1145G7 to maintain competitiveness against AMD's Ryzen 5000 mobile series. A notable improvement in this SKU is the doubling of usable PCIe 4.0 lanes to 16, allowing OEMs to connect high-speed NVMe storage and discrete components simultaneously without bottlenecking. It integrates Iris Xe-LP Graphics G7 with 80 Execution Units, providing robust integrated graphics for thin-and-light laptops. With a configurable TDP of 12W to 28W, it remains a highly capable processor for everyday productivity, media consumption, and light creative workloads, though it has been superseded by Intel's 12th Gen Alder Lake series.
