How does Core i5 14400F handle gaming, and how large is the gap versus cheaper models?

  The 14400F pairs nicely with a mid-range GPU: 1080p high-refresh exposes CPU single-core, memory, and engine limits, while 1440p/4K is basically the GPU's call.

  When comparing cheaper chips, fix the GPU, memory, driver, and power settings, then look at 1% lows in the same scene. If you game while streaming, recording, or compiling, watch whether the CPU stays fully loaded — extra threads hit the power and cooling ceiling sooner than gaming alone.
