Ryzen 5 3600 + RX 6600: what to expect at each resolution

1080p

At 1080p the CPU bottleneck is 18%, so the RX 6600 will often run below full load. You will feel it most in fast multiplayer games and in 1% lows (stutter). Expect about 70 FPS in Cyberpunk 2077, 104 FPS in Fortnite and 244 FPS in Counter-Strike 2 on High.

1440p

At 1440p the RX 6600 is the limit (1% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 50 FPS in Cyberpunk 2077, 74 FPS in Fortnite and 174 FPS in Counter-Strike 2 on High. The 8 GB of video memory runs short in Call of Duty: Black Ops 7 at these settings, so drop texture quality one step to avoid stutter.

4K

At 4K the RX 6600 is the limit (27% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 24 FPS in Cyberpunk 2077, 43 FPS in Fortnite and 102 FPS in Counter-Strike 2 on High. The 8 GB of video memory runs short in Call of Duty: Black Ops 7, Battlefield 6, Cyberpunk 2077, Hogwarts Legacy at these settings, so drop texture quality one step to avoid stutter. For 4K, turn on DLSS, FSR or XeSS in Quality or Balanced mode.

Ryzen 5 3600 + RX 6600: best upgrade for this build

This build is already near the limit of what the Ryzen 5 3600 can feed. A faster graphics card would push the bottleneck onto the CPU, so upgrade both together next time. See the best GPU for the Ryzen 5 3600 for the full list.

Ryzen 5 3600 + RX 6600: power supply for this pair

The Ryzen 5 3600 can draw up to about 88 W and the RX 6600 about 132 W. With 100 W for the rest of the system and 25% headroom, a good 450 W power supply (80 Plus Gold or better) is a safe choice. Use the PSU wattage calculator to include your exact drives, fans and overclocking.

Ryzen 5 3600 + RX 6600: settings tips for this pair

Raise graphics settings and resolution: the GPU has spare power, the CPU does not. Higher settings cost almost no FPS here.
Use native resolution or DLAA / FSR Native AA instead of a Performance upscaling mode, which would only shift more load to the CPU.
Lower CPU-heavy settings: crowd density, object view distance, physics and simulation quality.
Turn on XMP or EXPO so the RAM runs at its rated speed, and use two sticks for dual channel.
Close browsers, launchers and overlays while gaming to free up CPU time.

Ryzen 5 3600 + RX 6600: frequently asked questions

Does the Ryzen 5 3600 bottleneck the RX 6600?

Only at 1080p. The Ryzen 5 3600 limits the RX 6600 by 18% at 1080p, which mostly shows in high-frame-rate games. At 1440p (1% GPU) and 4K (27% GPU) the pair is balanced, so this is a good match for a 1440p monitor.

Is the Ryzen 5 3600 good enough for the RX 6600 at 1440p?

Yes. At 1440p the bottleneck is 1% GPU, which is in the balanced range, so you get close to the card’s full speed.

How many FPS does the Ryzen 5 3600 with the RX 6600 get?

On High settings we estimate about 73 FPS at 1080p and 53 FPS at 1440p on average across nine demanding games, for example 50 FPS in Cyberpunk 2077 at 1440p and 104 FPS in Fortnite at 1080p.

Should I upgrade the CPU or the GPU first?

The CPU. The graphics card already has spare power, so a faster GPU would add little until the processor is faster.

What power supply do I need for the Ryzen 5 3600 and RX 6600?

About 450 W from a good brand with an 80 Plus Gold rating. That covers the CPU (up to about 88 W), the graphics card (about 132 W), the rest of the system and some headroom.
