Ryzen 3 3300U vs Core i5-6400 comparison

In our benchmarks, the Ryzen 3 3300U beats the Core i5-6400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-6400 has a slightly higher clock speed compared to the Ryzen 3 3300U. Despite this, the Ryzen 3 3300U has a slightly higher turbo speed. A Ryzen 3 3300U CPU outputs less heat than a Core i5-6400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 3 3300U has more L2 cache than the Core i5-6400. Despite this, the Core i5-6400 has significantly more L3 cache compared to the Ryzen 3 3300U.

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 Ryzen 3 3300U has the same number of threads as cores. This means the the CPU does not support hyperthreading.
