Celeron N4020 vs Core 2 Duo T6400 benchmarks

Our benchmark analysis concludes that the Core 2 Duo T6400 performs better than the Celeron N4020. Furthermore, our gaming benchmark shows that it also outperforms the Celeron N4020 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core 2 Duo T6400 has a significantly higher clock speed than the Celeron N4020. A Celeron N4020 CPU outputs less heat than a Core 2 Duo T6400 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 N4020 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
