CPU Comparison
Intel Core i5-2540M vs Intel Core i5-450M
A side-by-side comparison of specs, performance and value. The Intel Core i5-2540M is a dual-core mobile processor built on the 32nm Sandy Bridge architecture, featuring Hyper-Threading for four threads and an integrated Intel HD 3000 GPU, designed for mainstream laptops released in early 2011.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks but struggles with large spreadsheets, heavy documents, or multitasking with many browser tabs.
Marginally faster than the i5-430M in CPU-bound tasks, but the difference is barely noticeable in real use.
Gaming
Cannot run modern AAA titles. Only suitable for very old or lightweight games at low resolutions.
Slightly better than the i5-430M but still entirely dependent on discrete graphics for any gaming capability.
Virtualization
Can run a single lightweight VM but lacks the cores and memory bandwidth for serious virtualization.
Slightly more headroom than the 430M but still impractical for serious VM workloads.
Efficiency
35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.
Same 35 W TDP with only ~6% more frequency than the i5-430M, resulting in slightly worse performance per watt.

Our Verdict on Each
The i5-2540M was a solid mid-range mobile chip in 2011, but it is now thoroughly outclassed by modern processors in every metric including efficiency, single-thread speed, and integrated graphics capability.
Best for: Upgrading an existing Socket G2 laptop at minimal cost
Read the full reviewThe i5-450M is a minor clock speed increase over the i5-430M that arrived just months before Sandy Bridge rendered the entire Arrandale lineup obsolete. Only relevant for existing Socket G1 laptop owners considering a cheap upgrade.
Best for: Found in an existing laptop at no additional cost
