Intel Xeon E5-2420 v2 vs Intel Xeon E5-620

Xeon E5-2420 v2 vs Xeon E5-620 specs and performance

In our benchmarks, the Xeon E5-620 beats the Xeon E5-2420 v2 in overall performance. Despite this, the Xeon E5-2420 v2 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2420 v2 has significantly more cores with 6 cores compared to the Xeon E5-620 that has 4 cores. It also has more threads than the Xeon E5-620. These CPUs have different clock speeds. Indeed, the Xeon E5-620 has a slightly higher clock speed compared to the Xeon E5-2420 v2. Despite this, the Xeon E5-2420 v2 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 E5-2420 v2 has more threads than cores. Each physical core is split into multiple threads.
