Intel Core i5-8400T vs Intel Core i7-2700K

Core i5-8400T vs Core i7-2700K comparison

In our benchmarks, the Core i5-8400T beats the Core i7-2700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-8400T has significantly more cores than the Core i7-2700K. Indeed, the Core i5-8400T has 6 cores compared to 4 cores found in the Core i7-2700K. Despite this, the Core i7-2700K has more threads than the Core i5-8400T. Our comparison shows that the Core i7-2700K has a significantly higher clock speed compared to the Core i5-8400T. Also, the Core i7-2700K has a slightly higher turbo speed. A Core i5-8400T CPU outputs less heat than a Core i7-2700K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-8400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
