Intel Core i7-6700 vs Intel Core i9-9900K

Core i7-6700 vs Core i9-9900K comparison

Our benchmark analysis concludes that the Core i9-9900K 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 i9-9900K has significantly more cores with 8 cores compared to the Core i7-6700 that has 4 cores. It also has more threads than the Core i7-6700. These CPUs have different clock speeds. Indeed, the Core i9-9900K has a slightly higher clock speed compared to the Core i7-6700. Also, the Core i9-9900K has a slightly higher turbo speed. A Core i7-6700 CPU outputs less heat than a Core i9-9900K 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 i9-9900K has significantly more L2 cache when compared to the Core i7-6700. The Core i9-9900K also has significantly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-6700 has more threads than cores. Each physical core is split into multiple threads.
