Core i5-6600K vs Ryzen 9 9950X3D comparison

Our benchmark analysis concludes that the Ryzen 9 9950X3D performs better than the Core i5-6600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6600K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Ryzen 9 9950X3D has significantly more cores than the Core i5-6600K. Indeed, the Ryzen 9 9950X3D has 16 cores compared to 4 cores found in the Core i5-6600K. It also has more threads than the Core i5-6600K. Our comparison shows that the Ryzen 9 9950X3D has a slightly higher clock speed compared to the Core i5-6600K. Also, the Ryzen 9 9950X3D has a significantly higher turbo speed. A Core i5-6600K CPU outputs less heat than a Ryzen 9 9950X3D 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 9 9950X3D has significantly more L2 cache when compared to the Core i5-6600K. The Ryzen 9 9950X3D also has significantly 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. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
