Core i5-6400 vs Xeon E5-2643 benchmarks

In our benchmarks, the Xeon E5-2643 beats the Core i5-6400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Xeon E5-2643 has more threads. Our comparison shows that the Xeon E5-2643 has a slightly higher clock speed compared to the Core i5-6400. Also, the Xeon E5-2643 has a slightly higher turbo speed. A Core i5-6400 CPU outputs less heat than a Xeon E5-2643 CPU because of its significantly lower TDP. 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. For instance, the Core i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
