Intel Pentium 5405U vs Intel Pentium 6405U

Pentium 5405U vs Pentium 6405U benchmarks

In our benchmarks, the Pentium 5405U beats the Pentium 6405U in overall performance. Despite this, the Pentium 6405U 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. Both these chips have an identical TDP (Thermal Design Power). 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 Pentium 5405U has more threads than cores. Each physical core is split into multiple threads.
