Overview

The Intel i5-480M is a mobile processor from Intel's first-generation Core i5 lineup, based on the Arrandale architecture. With a base clock speed of 2.66GHz and Turbo Boost up to 2.93GHz, it offers a viable upgrade for laptops equipped with Socket G1 that are running slower processors. The dual-core, four-thread design handles everyday computing tasks like web browsing, document editing, and media playback without issue, though it will show its age under heavier workloads.

As a drop-in replacement for compatible laptops, the i5-480M can breathe some additional life into an older machine without requiring a full system replacement. Its 35W thermal design power keeps it within the cooling capabilities of most laptop designs from that generation. However, users should be aware that this is a legacy part — it lacks support for modern instruction sets and is built on a 32nm process node, making it a practical but inherently limited upgrade option.
