Intel Core i5-8400T vs Intel Xeon E5-2660 v3

Core i5-8400T vs Xeon E5-2660 v3 comparison

Our benchmark analysis concludes that the Xeon E5-2660 v3 performs better than the Core i5-8400T. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400T in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2660 v3 has significantly more cores than the Core i5-8400T. Indeed, the Xeon E5-2660 v3 has 10 cores compared to 6 cores found in the Core i5-8400T. It also has more threads than the Core i5-8400T. These CPUs have different clock speeds. Indeed, the Xeon E5-2660 v3 has a significantly higher clock speed compared to the Core i5-8400T. Furthermore, both these CPUs have identical turbo speeds. A Core i5-8400T CPU outputs less heat than a Xeon E5-2660 v3 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. For instance, the Core i5-8400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
