Core i7-6500U vs Core i5-12400 benchmarks

According to the hardwareDB Benchmark tool, the Core i5-12400 is faster than the Core i7-6500U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6500U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-12400 has significantly more cores than the Core i7-6500U. Indeed, the Core i5-12400 has 6 cores compared to 2 cores found in the Core i7-6500U. It also has more threads than the Core i7-6500U. According to our data, the Core i7-6500U and Core i5-12400 have the same clock speed. Despite this, the Core i5-12400 has a slightly higher turbo speed. A Core i7-6500U CPU outputs less heat than a Core i5-12400 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. Indeed, the Core i7-6500U has more threads than cores. Each physical core is split into multiple threads.
