Intel Core i5-9600K vs Intel Core i9-9900K

Core i5-9600K vs Core i9-9900K specs and performance

In our benchmarks, the Core i9-9900K beats the Core i5-9600K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9600K in all gaming tests too.

With info from our database, we find that the Core i9-9900K has slightly more cores with 8 cores whereas the Core i5-9600K has 6 cores. It also has more threads than the Core i5-9600K. These CPUs have different clock speeds. Indeed, the Core i5-9600K has a slightly higher clock speed compared to the Core i9-9900K. Despite this, the Core i9-9900K has a slightly higher turbo speed. 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. The cache sizes of these CPUs are different. Indeed, the Core i9-9900K has slightly more L2 cache than the Core i5-9600K. The Core i9-9900K 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 i5-9600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
