Intel Xeon E5-2420 vs Intel Xeon E5-520

Xeon E5-2420 vs Xeon E5-520 benchmarks

In our benchmarks, the Xeon E5-2420 beats the Xeon E5-520 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-520 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2420 has significantly more cores than the Xeon E5-520. Indeed, the Xeon E5-2420 has 6 cores compared to 4 cores found in the Xeon E5-520. It also has more threads than the Xeon E5-520. With our hardware info, we find that the Xeon E5-520 has a slightly higher clock speed than the Xeon E5-2420. Also, the Xeon E5-520 has a slightly higher turbo speed. The Xeon E5-520 outputs less heat than Xeon E5-2420 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 Xeon E5-2420 has more threads than cores. Each physical core is split into multiple threads.
