Intel Pentium Gold G6405 vs Intel Xeon E5-520

Pentium Gold G6405 vs Xeon E5-520 benchmarks

In our benchmarks, the Xeon E5-520 beats the Pentium Gold G6405 in overall performance. Despite this, the Pentium Gold G6405 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-520 has significantly more cores with 4 cores compared to the Pentium Gold G6405 that has 2 cores. But they both have the same number of threads. Our comparison shows that the Pentium Gold G6405 has a significantly higher clock speed compared to the Xeon E5-520. A Pentium Gold G6405 CPU outputs less heat than a Xeon E5-520 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 Pentium Gold G6405 has more threads than cores. Each physical core is split into multiple threads.
