Core i7-8700 vs Core i5-12400 benchmarks

According to the hardwareDB Benchmark tool, the Core i5-12400 is faster than the Core i7-8700. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-8700 has a slightly higher clock speed compared to the Core i5-12400. Also, the Core i7-8700 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-8700 has more threads than cores. Each physical core is split into multiple threads.
