Pentium G3240 vs Pentium G645 comparison

Our benchmark analysis concludes that the Pentium G3240 performs better than the Pentium G645. 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 and the same number of threads. With our hardware info, we find that the Pentium G3240 has a slightly higher clock speed than the Pentium G645. A Pentium G3240 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. For instance, the Pentium G3240 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
