Intel Core i3-4005U vs Intel Celeron 2957U

The Intel Core i3-4005U belongs to the Haswell-U architecture and is manufactured using the 22-nanometer process.

This processor is aimed at budget-conscious users of compact notebooks. It features two physical cores and supports Hyper-Threading, enabling the simultaneous processing of four threads. In benchmarks for single-core and multi-core performance, the Intel Core i3-4005U is significantly ahead of the comparison model.

Thanks to the integrated Intel HD Graphics 4400, graphical performance is sufficient for simple tasks, with a memory bandwidth of 26 GB/s supporting data processing. The Thermal Design Power is 15 watts, which facilitates efficient cooling in slim chassis. Due to its higher computing capacity, this model offers a solid price-performance ratio for daily office applications and media consumption in a mobile work environment.

The Intel Celeron 2957U is also based on the Haswell-U architecture and is produced in 22-nanometer technology.

It is primarily designed for entry-level laptops and very affordable office devices. In contrast to the Intel Core i3-4005U, the Intel Celeron 2957U has only two cores without Hyper-Threading, which limits parallel task processing. Performance in single- and multi-core scenarios is noticeably lower in direct comparison.

With Intel HD Graphics (Haswell GT1) and a memory bandwidth of 13 GB/s, graphical performance is limited to basic visual displays. With a TDP of 15 watts, heat generation remains moderate, allowing for simple cooling systems. The Intel Celeron 2957U is priced very low, qualifying it for the simplest web applications.

For more demanding software, however, the Intel Core i3-4005U is the more stable recommendation.
