We can better compare what are the technical differences between the two processors.

Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We see that the two processors have an equivalent number of cores, the turbo frequency of Intel Core i5-2400 is bigger, that the PDT of Intel Core i5-6400 is lower. The Intel Core i5-6400 was designed earlier.

Performance comparison with the benchmarks:

Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench.

In single core, the difference is 6%. In multi-core, the differential gap is 18%.

Note: Commissions may be earned from the links above. These scores are only an
average of the performances got with these processors, you may get different results.

CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.

Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.

Cinebench R23 is cross-platform testing software that allows you to assess the hardware capabilities of a device such as a computer, tablet, server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant. The test scene contains no less than 2,000 objects and more than 300,000 polygons in total.
