Xeon E5-2620 vs Xeon E5-2623 v3 benchmarks

According to the hardwareDB Benchmark tool, the Xeon E5-2620 is faster than the Xeon E5-2623 v3. Despite this, the Xeon E5-2623 v3 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2620 has significantly more cores than the Xeon E5-2623 v3. Indeed, the Xeon E5-2620 has 6 cores compared to 4 cores found in the Xeon E5-2623 v3. It also has more threads than the Xeon E5-2623 v3. Our comparison shows that the Xeon E5-2623 v3 has a significantly higher clock speed compared to the Xeon E5-2620. Also, the Xeon E5-2623 v3 has a slightly higher turbo speed. A Xeon E5-2620 CPU outputs less heat than a Xeon E5-2623 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 E5-2620 has more threads than cores. Each physical core is split into multiple threads.
