Estimated FPS With an RTX 5080
A processor's gaming performance only shows when the graphics card is not the limit. With an RTX 5080, 1080p favours the Core i5-9600K by 2%, 1440p favours the Core i5-9600K by 2%, 4K favours the Core i5-9600K by 1%, which is why the higher the resolution, the less the processor matters. Figures come from our performance model, not from measurements on your PC.
Frame Rate Limit in Popular Games
| Game (settings) | Ryzen 5 3600 | Core i5-9600K |
|---|---|---|
| Cyberpunk 2077 (High, no ray tracing) | ~85 | ~85 |
| Fortnite (High, DirectX 12) | ~125 | ~125 |
| Call of Duty: Black Ops 6 (High) | ~110 | ~110 |
| Counter-Strike 2 (High) | ~215 | ~220 |
The most frames each processor can feed in that game with an unlimited graphics card, rounded to the nearest 5 FPS. Your real frame rate is the lower of this and what your card can render.
Verdict: Ryzen 5 3600 or Core i5-9600K?
The Ryzen 5 3600 and Core i5-9600K are effectively tied in games, with frame rate limits of 98 and 100 FPS. Neither will hold back a graphics card noticeably more than the other.
In multi-threaded work the Core i5-9600K scores 12% higher on 6 threads, which shows up in rendering, video encoding, compiling and streaming while gaming.
The Ryzen 5 3600 has 6 cores and 12 threads against 6 and 6 on the Core i5-9600K. At eight threads or fewer, modern games start to stutter in busy scenes before the average frame rate shows it.
They sit on different platforms: the Ryzen 5 3600 uses AM4 with DDR4, the Core i5-9600K uses LGA 1151 with DDR4. Switching between them means a new motherboard, which often costs more than the gap between the processors.
Bottom line: pick on platform cost and price, not performance.
