The Intel Core i5-4200U processor can be found in mid-range ultrabooks and standard laptops. It’s the most commonly used laptop CPU from the latest “Haswell” or 4th Gen Intel Core family, besides the Core i7-4500U.
The i5-4200U has two cores, running at clock speeds between 1.6 and 2.6GHz. This 22-nanometer CPU has 3MB of L3 cache and consumes 15W of power. The integrated graphics processor inside the chip is the Intel HD 4400 series, bringing noticeable performance boost over the previous generation HD 4000. Overall, the CPU itself is optimized for day-to-day computing tasks and occasionally photo and video editing. Some basic 3D gaming is possible with the HD 4400.

According to PassMark benchmark database, the i5-4200U provides a noticeable performance increase over the comparable i5 from the previous 3rd Generation “Ivy Bridge” Core series – the i5-3317U which also runs at up to 2.6GHz. In addition, the 4200U brings a reduced power consumption of 15 Watts, down from 17W.

As expected, it fell behind the i7-4500U which is a step above the i5-4200U in the Haswell ultra-low voltage CPU hierarchy, and also the full-voltage i5-4200M running at up to 3.1GHz. However, the 4200M consumes more than double energy – 37W, so it isn’t suitable for thin laptops with usually small batteries. On the other hand, in comparison against the i3-4010U Haswell, the 4200U shines. That’s primarily because of presence of TurboBoost technology on the i5, allowing maximal 2.6GHz on demand, while the i3 is fixed at 1.7GHz.
