Pentium 6405U vs Pentium G2120 comparison

Our benchmark analysis concludes that the Pentium 6405U performs better than the Pentium G2120. Despite this, the Pentium G2120 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Pentium 6405U has more threads. A Pentium 6405U CPU outputs less heat than a Pentium G2120 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 Pentium 6405U has more threads than cores. Each physical core is split into multiple threads.
