Core i3-7100 vs Core i7-975 benchmarks

Our benchmark analysis concludes that the Core i7-975 performs better than the Core i3-7100. Despite this, the Core i3-7100 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7-975 has significantly more cores than the Core i3-7100. Indeed, the Core i7-975 has 4 cores compared to 2 cores found in the Core i3-7100. It also has more threads than the Core i3-7100. These CPUs have different clock speeds. Indeed, the Core i3-7100 has a slightly higher clock speed compared to the Core i7-975. A Core i3-7100 CPU outputs less heat than a Core i7-975 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. Indeed, the Core i3-7100 has more threads than cores. Each physical core is split into multiple threads.
