Performance Compared

Productivity

Intel Core i5-2540M (BGA)Best35

Adequate for word processing and spreadsheets but slow with modern web applications.

Intel Core i5-450M28

Marginally faster than the i5-430M in CPU-bound tasks, but the difference is barely noticeable in real use.

Gaming

Intel Core i5-2540M (BGA)Best15

Intel HD 3000 cannot handle modern games. Only legacy titles at minimum settings are playable.

Intel Core i5-450M9

Slightly better than the i5-430M but still entirely dependent on discrete graphics for any gaming capability.

Virtualization

Intel Core i5-2540M (BGA)Best20

Supports VT-x and VT-d but only 2 cores limit practical virtualization use.

Intel Core i5-450M16

Slightly more headroom than the 430M but still impractical for serious VM workloads.

Efficiency

Intel Core i5-2540M (BGA)Best25

35 W TDP is modest for 2011 but inefficient compared to any modern mobile processor.

Intel Core i5-450M20

Same 35 W TDP with only ~6% more frequency than the i5-430M, resulting in slightly worse performance per watt.

Our Verdict on Each

Functionally identical to the rPGA variant in performance, but the BGA packaging means it cannot be upgraded or replaced, which is a significant limitation for long-term usability.

Best for: None, as the BGA variant cannot be purchased separately for upgrades

Read the full review

The 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
