Quick answer
The Ryzen 7 7800X3D is the faster gaming CPU: its FPS ceiling is about 21% higher than the Core i5-14600K’s (score 87 vs 72). They use different platforms (LGA 1700 vs AM5), so the motherboard and memory differ too. With a mid-range graphics card at 1440p or 4K, the gap mostly disappears because the card sets the frame rate.

Platform, Power and Upgrades
- Core i5-14600K: LGA 1700, DDR4 or DDR5, depending on the board (never both), up to about 181W. Upgrade path on the same board: up to the Core i9-14900K.
- Ryzen 7 7800X3D: AM5, DDR5 only, up to about 162W. Upgrade path on the same board: up to the Ryzen 7 9800X3D.
Which Should You Buy?
- For high-refresh gaming, esports or a fast graphics card, the Ryzen 7 7800X3D is about 21% quicker.
- With a mid-range card at 1440p or 4K the Core i5-14600K gives up little, so it makes sense when it costs clearly less.
- Count the motherboard and RAM in the price: a new socket can mean a new board and, for DDR5-only platforms, new memory.
- For streaming, video editing or other multi-threaded work, the Core i5-14600K’s 14 cores help more than our gaming score shows.
