Intel Core i9-14900K vs AMD Ryzen 9 7950X3D: specs comparison

Intel Core i9-14900K came out in 2023 (Raptor Lake Refresh, Intel 7), AMD Ryzen 9 7950X3D in 2023 (Zen 4 + 3D V-Cache, TSMC 5 nm). Cores and threads: 24/32 on i9-14900K vs 16/32 on Ryzen 9 7950X3D. Max clock: 6 GHz vs 5.7 GHz. L3 cache: 36 MB vs 128 MB. i9-14900K uses the LGA1700 socket, Ryzen 9 7950X3D uses AM5: they need different motherboards. Clocks from different vendors are not directly comparable, so those rows are not highlighted.

In short. The table below is built from the official spec sheets. Green marks the best value in a row. This is not a benchmark: check tests in the games and apps you use.

How to use it

  1. Compare cores and threads — they matter most for video editing, 3D and multitasking.
  2. For gaming, clock speed and L3 cache matter more — especially on AMD X3D chips.
  3. Check the socket and supported memory: will the CPU fit your board.
  4. To add a third processor, press “Change models or add a third”.
