Intel Core i3-7100 vs Intel Core i7-7700K

Core i3-7100 vs Core i7-7700K specs and performance

Our benchmark analysis concludes that the Core i7-7700K performs better than the Core i3-7100. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-7100 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-7700K has significantly more cores than the Core i3-7100. Indeed, the Core i7-7700K has 4 cores compared to 2 cores found in the Core i3-7100. It also has more threads than the Core i3-7100. Our comparison shows that the Core i7-7700K has a slightly higher clock speed compared to the Core i3-7100. A Core i3-7100 CPU outputs less heat than a Core i7-7700K CPU because of its 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 i7-7700K has significantly more L2 cache than the Core i3-7100. The Core i7-7700K also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i3-7100 has more threads than cores. Each physical core is split into multiple threads.
