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

Core i7-6700K vs Core i7-9700 comparison

According to the hardwareDB Benchmark tool, the Core i7-9700 is faster than the Core i7-6700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-9700 has significantly more cores with 8 cores compared to the Core i7-6700K that has 4 cores. But they both have the same number of threads. With our hardware info, we find that the Core i7-6700K has a slightly higher clock speed than the Core i7-9700. Despite this, the Core i7-9700 has a slightly higher turbo speed. The Core i7-9700 outputs less heat than Core i7-6700K thanks to a significantly 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 i7-9700 has significantly more L2 cache than the Core i7-6700K. The Core i7-9700 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 i7-6700K has more threads than cores. Each physical core is split into multiple threads.
