The short answer
In a typical one of 8 popular games at 1080p High with an RTX 5090, the Core i9-13900K gets about 173 FPS and the Core i9-14900K about 176 FPS. With a slower graphics card, or at 1440p and 4K, the card sets the FPS more often and the gap gets smaller.
Both use the LGA1700 socket. Both take DDR4/DDR5 memory. Cores and threads: 24 / 32 on the Core i9-13900K, 24 / 32 on the Core i9-14900K. Neither comes with a cooler, so budget for one.
Core i9-13900K vs Core i9-14900K: FPS in popular games
Estimated FPS at 1080p High with 32 GB RAM (Core i9-13900K / Core i9-14900K in each column). With an RTX 5090, the processor sets the frame rate wherever it can. Values above 500 show as 500+. See FPS for your own PC.
| Game | RTX 5090 | RTX 5060 |
|---|---|---|
| Counter-Strike 2 | 396 / 403 | 305 / 305 |
| Valorant | 436 / 443 | 436 / 443 |
| Fortnite | 190 / 193 | 164 / 164 |
| Apex Legends | 174 / 177 | 174 / 177 |
| Marvel Rivals | 135 / 137 | 89 / 89 |
| Call of Duty: Black Ops 6 | 173 / 176 | 110 / 110 |
| Cyberpunk 2077 | 139 / 142 | 104 / 104 |
| Baldur's Gate 3 | 141 / 143 | 141 / 143 |
With a mid-range graphics card such as an RTX 5060, the card sets the frame rate in more games, so the difference between the two processors is smaller.
