A6-7400K vs A9-9420 specs and performance
Our benchmark analysis concludes that the A6-7400K performs better than the A9-9420. Furthermore, our gaming benchmark shows that it also outperforms the A9-9420 in all gaming tests too.
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 A6-7400K has a slightly higher clock speed compared to the A9-9420. Also, the A6-7400K has a slightly higher turbo speed. The A9-9420 outputs less heat than A6-7400K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache
Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the A6-7400K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
