Pentium Gold G6405 vs Xeon E3-1220 comparison

Our benchmark analysis concludes that the Xeon E3-1220 performs better than the Pentium Gold G6405. 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 E3-1220 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 slightly higher clock speed compared to the Xeon E3-1220. A Pentium Gold G6405 CPU outputs less heat than a Xeon E3-1220 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 Pentium Gold G6405 has more threads than cores. Each physical core is split into multiple threads.
