Core i3-6100 vs Core i7-6700 comparison

According to the hardwareDB Benchmark tool, the Core i7-6700 is faster than the Core i3-6100. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-6100 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-6700 has significantly more cores than the Core i3-6100. Indeed, the Core i7-6700 has 4 cores compared to 2 cores found in the Core i3-6100. It also has more threads than the Core i3-6100. With our hardware info, we find that the Core i3-6100 has a slightly higher clock speed than the Core i7-6700. A Core i3-6100 CPU outputs less heat than a Core i7-6700 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 i7-6700 has significantly more L2 cache than the Core i3-6100. The Core i7-6700 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 i3-6100 has more threads than cores. Each physical core is split into multiple threads.
