A6-6400K vs Pentium 5405U specs and performance
Our benchmark analysis concludes that the Pentium 5405U performs better than the A6-6400K. Despite this, the A6-6400K has the advantage in our gaming benchmark.
In terms of the number of cores of each of these CPUs, the Pentium 5405U has significantly more cores than the A6-6400K. Indeed, the Pentium 5405U has 2 cores compared to 1 cores found in the A6-6400K. It also has more threads than the A6-6400K. The Pentium 5405U outputs less heat than A6-6400K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
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. Indeed, the A6-6400K has more threads than cores. Each physical core is split into multiple threads.
