Xeon E5-2665 vs Xeon E5-2678 v3 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E5-2665 is faster than the Xeon E5-2678 v3. Despite this, the Xeon E5-2678 v3 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 Xeon E5-2665 that has 8 cores. It also has more threads than the Xeon E5-2665. A Xeon E5-2665 CPU outputs less heat than a Xeon E5-2678 v3 CPU because of its 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 Xeon E5-2665 has more threads than cores. Each physical core is split into multiple threads.
