Ryzen 5 3450U vs Core i5-6600K specs and performance

In our benchmarks, the Core i5-6600K beats the Ryzen 5 3450U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 3450U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Ryzen 5 3450U has more threads. With our hardware info, we find that the Core i5-6600K has a significantly higher clock speed than the Ryzen 5 3450U. A Ryzen 5 3450U CPU outputs less heat than a Core i5-6600K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 5 3450U has significantly more L2 cache when compared to the Core i5-6600K. Despite this, the Core i5-6600K has significantly more L3 cache compared to the Ryzen 5 3450U.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Ryzen 5 3450U has more threads than cores. Each physical core is split into multiple threads.
