Intel Pentium Gold G6400 vs Intel Xeon E3-1220

Pentium Gold G6400 vs Xeon E3-1220 specs and performance

In our benchmarks, the Xeon E3-1220 beats the Pentium Gold G6400 in overall performance. Despite this, the Pentium Gold G6400 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E3-1220 has significantly more cores than the Pentium Gold G6400. Indeed, the Xeon E3-1220 has 4 cores compared to 2 cores found in the Pentium Gold G6400. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Pentium Gold G6400 has a slightly higher clock speed compared to the Xeon E3-1220. A Pentium Gold G6400 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Pentium Gold G6400 has more threads than cores. Each physical core is split into multiple threads.
