Automatic overclocking

Many people mistakenly consider the Core i5-7400 a weak processor, complaining about its low nominal frequency - only 3 GHz. The next i5-7500 chip in the lineup operates at a frequency of 3.4 GHz, which is significantly higher (plus 400 MHz). But it is more correct to compare not the nominal frequency of processors, but the Turbo Boost frequency for all four cores. For the 7400 it is 3.4 GHz, and for the 7500 it is 3.6 GHz. The advantage of 200 MHz is clearly not worth the overpayment, and the Core i5-7400 is the best choice for your money.

FPS Growth

The integrated Intel HD 630 graphics accelerator has the same 24 micro-cores as the old HD 530, which delivered a reasonable 30 FPS in GTA V, Fallout 4 and Battlefield 1, albeit at 720p with low graphics settings. The transition from DDR4-2133 MHz RAM to a slightly faster 2400 MHz, which is used as video memory in the case of integrated graphics, adds an additional 3-5 FPS.

A vision for the future

Best of all, the Core i5-7400 is suitable for building a gaming PC with a GeForce GTX 1070-level graphics card, the potential of which even an overclocked Core i3 does not reveal. However, even if you buy a simpler graphics card for the first time, still do not be stingy with the i5-7400 so that in the event of a future PC upgrade you do not have to think about replacing the processor.
