Core i5-14400F vs Core i5-13400F: Gaming Performance & Bottleneck (2026)

You won't feel a difference between the Core i5-14400F and Core i5-13400F in most games. With an RTX 5090 at 1080p High, our model has them at 128 vs 126 FPS. In esports games like CS2 it's 333 vs 328 FPS, and in CPU-heavy titles such as Microsoft Flight Simulator 70 vs 69 FPS at 1440p. 1% lows, which decide how smooth a game feels, come in at 90 vs 88 FPS. With a more typical RTX 5070 at 1440p they land at 99 and 99 FPS, effectively the same. Both use LGA1700, so moving from one to the other is a drop-in swap. With gaming performance this close, the price of the chip, the motherboard and the cooler matters more than the benchmark. Both have 10 cores and 16 threads. Under a 10% CPU bottleneck at 1440p, the Core i5-14400F can drive up to the RTX 5080 and the Core i5-13400F up to the RX 7900 XTX.

Which should you buy?

For gaming this is a wash, so the decision comes down to price, platform and what else you do with the PC.

Buy the Core i5-14400F if…

  • you plan a faster graphics card: it keeps up with GPUs up to the RTX 5080 at 1440p.
  • it's the cheaper of the two where you shop: gaming performance is close enough that price decides.

Buy the Core i5-13400F if…

  • you pair it with a mid-range card: with an RTX 5070 at 1440p the two are level.
  • it's the cheaper of the two where you shop: gaming performance is close enough that price decides.
