Celeron J4125 vs Pentium G645 benchmarks

According to the hardwareDB Benchmark tool, the Celeron J4125 is faster than the Pentium G645. Despite this, the Pentium G645 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Celeron J4125 has significantly more cores than the Pentium G645. Indeed, the Celeron J4125 has 4 cores compared to 2 cores found in the Pentium G645. It also has more threads than the Pentium G645. These CPUs have different clock speeds. Indeed, the Pentium G645 has a significantly higher clock speed compared to the Celeron J4125. A Celeron J4125 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. For instance, the Celeron J4125 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
