- In some games, a processor with a higher clock speed, or with the technical name IPC (Instructions per clock), performs better than other processors with more cores and a lower core frequency.
- The i5-7600K has a higher turbo clock. Turbo Boost is a processor feature that will run at a processor clock speed faster than its base clock speed if certain conditions are present. This will allow older software that runs on fewer cores to run better on newer hardware. Since games are also software, they are also applicable.
i5-8400
- The i5-8400 has a higher level 3 cache. This is useful when you have significant multi-processor workloads, many computational processes at the same time. Rather on a server rather than a personal computer for interactive workloads.
- The i5-8400 has more cores. The advantage of having more cores is that the system can handle more threads. Each core can process a separate data stream.
This architecture greatly improves the performance of a system running parallel applications. - The i5-8400 has more themes. Large programs are divided into threads (small sections) so that the processor can execute them simultaneously to speed up execution.
- i5-8400 The i5-8400 is more energy efficient and generates less heat.
