Pentium Gold G6405 vs Pentium G645 specs and performance

In our benchmarks, the Pentium Gold G6405 beats the Pentium G645 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Pentium G645 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Pentium Gold G6405 has more threads. Our comparison shows that the Pentium Gold G6405 has a slightly higher clock speed compared to the Pentium G645. A Pentium Gold G6405 CPU outputs less heat than a Pentium G645 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.
