CPU Comparison
Intel Core i5-1155G7 (IPU) vs Intel Core i5-1240P
A side-by-side comparison of specs, performance and value. The Intel Core i5-1155G7 (IPU) is a specialized 11th Gen Tiger Lake-U refresh processor released in mid-2021, designed explicitly for premium laptops emphasizing advanced camera and vision capabilities. The '(IPU)' designation indicates the inclusion of Intel's Image Processing Unit 6.0, enabling high-quality hardware-level image processing for features like AI-enhanced auto-framing, gaze correction, and background blur without taxing the CPU. Built on the 10nm SuperFin process, this 4-core, 8-thread chip operates at a base clock of 2.5 GHz and boosts up to 4.5 GHz. It features Iris Xe-LP Graphics G7 with 80 Execution Units, delivering strong integrated graphical performance. With a default 28W TDP configurable down to 12W, it balances power and performance for ultrabooks. This processor was highly sought after during the remote-work boom, as it provided OEMs with a turnkey solution to significantly improve webcam quality in thin-and-light laptops without requiring discrete camera components.
