Intel Core i7-10700KF vs Intel Core i5-12400

Core i7-10700KF vs Core i5-12400 specs and performance

In our benchmarks, the Core i7-10700KF beats the Core i5-12400 in overall performance. Despite this, the Core i5-12400 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-10700KF has slightly more cores with 8 cores compared to the Core i5-12400 that has 6 cores. It also has more threads than the Core i5-12400. Our comparison shows that the Core i7-10700KF has a significantly higher clock speed compared to the Core i5-12400. Also, the Core i7-10700KF has a slightly higher turbo speed. The Core i5-12400 outputs less heat than Core i7-10700KF thanks to a 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 i7-10700KF has more threads than cores. Each physical core is split into multiple threads.
