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