Performance Compared

Productivity

Intel Core i5-2500Best35

Adequate for legacy office suites, but modern web browsers and productivity apps will feel sluggish.

Intel Core i5-2450P32

Slightly faster than the i5-2400 in CPU-bound legacy tasks.

Gaming

Intel Core i5-250018

When paired with a contemporary discrete GPU, it could handle 2011-era games well, but is completely bottlenecked for modern titles.

Intel Core i5-2450PBest25

Excellent for pre-2015 games when paired with a capable mid-range GPU.

Virtualization

Intel Core i5-250040

Supports VT-x and VT-d, but four threads restrict the number of useful virtual machines.

Intel Core i5-2450P40

Good for headless server virtualization where iGPU is not needed.

Efficiency

Intel Core i5-250040

Consumes up to 95 W under load, which is high by modern efficiency standards.

Intel Core i5-2450PBest58

More efficient per watt than GPU-enabled Sandy Bridge parts under CPU load.
