Intel Core i7-6700 vs Intel Core i7-9700K

Core i7-6700 vs Core i7-9700K benchmarks

Our benchmark analysis concludes that the Core i7-9700K performs better than the Core i7-6700. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-9700K has significantly more cores with 8 cores compared to the Core i7-6700 that has 4 cores. But they both have the same number of threads. Our comparison shows that the Core i7-9700K has a slightly higher clock speed compared to the Core i7-6700. Also, the Core i7-9700K has a slightly higher turbo speed. A Core i7-6700 CPU outputs less heat than a Core i7-9700K 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 Core i7-9700K has significantly more L2 cache when compared to the Core i7-6700. The Core i7-9700K 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. Indeed, the Core i7-6700 has more threads than cores. Each physical core is split into multiple threads.
