Celeron G4920 vs Pentium G645 comparison

According to the hardwareDB Benchmark tool, the Celeron G4920 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 and the same number of threads. These CPUs have different clock speeds. Indeed, the Celeron G4920 has a slightly higher clock speed compared to the Pentium G645. A Celeron G4920 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 data shows that both these CPUs have same sized L2 caches. The Celeron G4920 also has significantly more L3 cache.

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. For instance, the Celeron G4920 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
