Intel Core i5-8400 vs Intel Core i5-2400

Core i5-8400 vs Core i5-2400 comparison

According to the hardwareDB Benchmark tool, the Core i5-8400 is faster than the Core i5-2400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-2400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8400 has significantly more cores with 6 cores compared to the Core i5-2400 that has 4 cores. It also has more threads than the Core i5-2400. These CPUs have different clock speeds. Indeed, the Core i5-2400 has a slightly higher clock speed compared to the Core i5-8400. Despite this, the Core i5-8400 has a slightly higher turbo speed. A Core i5-8400 CPU outputs less heat than a Core i5-2400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
