According to current Leak, the new slightly overclocked Intel Core i3-8350k with four cores without hyperthreading in single-core performance is even superior to the current Intel Core i7-7700k.
According to a Leak, the Intel Core i3-8350k is a much more powerful processor chip than previously thought. In the Leak, a slightly overclocked model in the single-core performance even surpassed the current Intel Core i7-7700k. So the overclocked to 4.0 GHz, Intel Core i3-8350k scored in CPU-Z benchmark 503 points, while the Intel Core i7-7700k scored only 492 points, closely followed. Even if the difference is not particularly dramatic, it should be considered that the current flagship has been beaten by an entry-level processor.
Intel is working on increasing the number of cores for Cofee Lake processors. Thus, Intel i3 processors have always been dual-core processors, which were provided by hyper threading a total of 4 threads. This is changing since Intel in the 8th generation renounced hyperthreading, and opted for a native quad core processor in its entry models.
This upgrade of the processors can be attributed to the new competition of AMD with its Ryzen processors. AMD Ryzen is already offering processors with 6 cores plus multithreading, which cost only 200 US dollars (AMD Ryzen 5 1600).
