Intel Core i5-8400 vs Intel Core i7-10700T

Core i5-8400 vs Core i7-10700T specs and performance

In our benchmarks, the Core i7-10700T beats the Core i5-8400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-10700T has slightly more cores with 8 cores compared to the Core i5-8400 that has 6 cores. It also has more threads than the Core i5-8400. Our comparison shows that the Core i5-8400 has a slightly higher clock speed compared to the Core i7-10700T. Despite this, the Core i7-10700T has a slightly higher turbo speed. The Core i7-10700T outputs less heat than Core i5-8400 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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
