Key differences

  • Both use the LGA 1700 socket. Check a motherboard's CPU support list before swapping one for the other; older boards can need a BIOS update.
  • The Core i5-12600K boosts to 4.9 GHz, 0.2 GHz higher than the Core i5-14400.
  • The Core i5-14400 is rated at 65 W TDP against 125 W, so it is easier to cool and puts less load on the power supply.
