Xeon E5-2620 vs Xeon E5-2643 benchmarks

In our benchmarks, the Xeon E5-2620 beats the Xeon E5-2643 in overall performance. Despite this, the Xeon E5-2643 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2620 has significantly more cores with 6 cores compared to the Xeon E5-2643 that has 4 cores. It also has more threads than the Xeon E5-2643. With our hardware info, we find that the Xeon E5-2643 has a significantly higher clock speed than the Xeon E5-2620. Also, the Xeon E5-2643 has a slightly higher turbo speed. A Xeon E5-2620 CPU outputs less heat than a Xeon E5-2643 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Xeon E5-2620 has more threads than cores. Each physical core is split into multiple threads.
