Core i3-8100 vs Core i7-4790K benchmarks

Our benchmark analysis concludes that the Core i7-4790K performs better than the Core i3-8100. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-8100 in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i7-4790K has more threads. With our hardware info, we find that the Core i7-4790K has a slightly higher clock speed than the Core i3-8100. Also, the Core i7-4790K has a slightly higher turbo speed. A Core i3-8100 CPU outputs less heat than a Core i7-4790K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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