Core i7-640M vs Pentium G2020 benchmarks

Our benchmark analysis concludes that the Core i7-640M performs better than the Pentium G2020. Despite this, the Pentium G2020 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-640M has more threads. These CPUs have different clock speeds. Indeed, the Pentium G2020 has a slightly higher clock speed compared to the Core i7-640M. A Core i7-640M CPU outputs less heat than a Pentium G2020 CPU because of its significantly 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 Core i7-640M has more threads than cores. Each physical core is split into multiple threads.
