Intel Core i3-8100 vs Intel Core i7-2700K

Core i3-8100 vs Core i7-2700K benchmarks

In our benchmarks, the Core i3-8100 beats the Core i7-2700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-2700K has more threads. These CPUs have different clock speeds. Indeed, the Core i3-8100 has a slightly higher clock speed compared to the Core i7-2700K. Despite this, the Core i7-2700K has a slightly higher turbo speed. A Core i3-8100 CPU outputs less heat than a Core i7-2700K CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. For instance, the Core i3-8100 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
