Core i5-10400F vs Xeon E5-2678 v3 specs and performance

In our benchmarks, the Xeon E5-2678 v3 beats the Core i5-10400F in overall performance. Despite this, the Core i5-10400F has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2678 v3 has significantly more cores with 12 cores compared to the Core i5-10400F that has 6 cores. It also has more threads than the Core i5-10400F. A Core i5-10400F CPU outputs less heat than a Xeon E5-2678 v3 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. Indeed, the Core i5-10400F has more threads than cores. Each physical core is split into multiple threads.
