Intel Core i7-8086K vs Intel Core i9-9900KS

Core i7-8086K vs Core i9-9900KS comparison

In our benchmarks, the Core i9-9900KS beats the Core i7-8086K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8086K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-9900KS has slightly more cores with 8 cores compared to the Core i7-8086K that has 6 cores. It also has more threads than the Core i7-8086K. These CPUs have different clock speeds. Indeed, the Core i9-9900KS has a slightly higher clock speed compared to the Core i7-8086K. In addition, both chips have the same turbo speed. A Core i7-8086K CPU outputs less heat than a Core i9-9900KS CPU because of its slightly lower TDP. 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 i9-9900KS has slightly more L2 cache than the Core i7-8086K. The Core i9-9900KS 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 Core i7-8086K has more threads than cores. Each physical core is split into multiple threads.
