Pentium Gold G6400 vs Pentium G4620 comparison

Our benchmark analysis concludes that the Pentium Gold G6400 performs better than the Pentium G4620. Furthermore, our gaming benchmark shows that it also outperforms the Pentium G4620 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Pentium Gold G6400 has a slightly higher clock speed compared to the Pentium G4620. The Pentium G4620 outputs less heat than Pentium Gold G6400 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Pentium Gold G6400 also has slightly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Pentium Gold G6400 has more threads than cores. Each physical core is split into multiple threads.
