Core i9-7940X vs Xeon E5-2678 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-2678 v3 is faster than the Core i9-7940X. Despite this, the Core i9-7940X has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i9-7940X has slightly more cores with 14 cores compared to the Xeon E5-2678 v3 that has 12 cores. It also has more threads than the Xeon E5-2678 v3. The Xeon E5-2678 v3 outputs less heat than Core i9-7940X thanks to a slightly 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 i9-7940X has more threads than cores. Each physical core is split into multiple threads.
