Pentium 6405U vs Pentium G645 benchmarks

According to the hardwareDB Benchmark tool, the Pentium 6405U is faster than the Pentium G645. Despite this, the Pentium G645 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Pentium 6405U has more threads. A Pentium 6405U CPU outputs less heat than a Pentium G645 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.
