Does the Ryzen 5 5600 Bottleneck the RTX 3070?

Short answer: Only at 1080p. The Ryzen 5 5600 limits the RTX 3070 by 22% at 1080p, which mostly shows in high-frame-rate games. At 1440p (5% CPU) and 4K (23% GPU) the pair is balanced, so this is a good match for a 1440p monitor.

Best resolution for this pair: 1440p
Bottleneck: 22% CPU at 1080p, 5% CPU at 1440p, 23% GPU at 4K
Average FPS (9 demanding games, High): 98 at 1080p, 72 at 1440p, 39 at 4K
Recommended power supply: 550 W or more

Ryzen 5 5600 + RTX 3070 bottleneck at 1080p, 1440p and 4K

Resolution	Bottleneck	Limiting part	What it means
1080p	22%	CPU (moderate)	The CPU often holds the card back. Free fixes help; a CPU upgrade helps more.
1440p	5%	CPU (balanced)	Balanced. Both parts are well used.
4K	23%	GPU (moderate)	The graphics card is fully used. This is the normal, healthy kind of limit.

Ryzen 5 5600 + RTX 3070: what to expect at each resolution

1080p

At 1080p the CPU bottleneck is 22%, so the RTX 3070 will often run below full load. You will feel it most in fast multiplayer games and in 1% lows (stutter). Expect about 95 FPS in Cyberpunk 2077, 140 FPS in Fortnite and 330 FPS in Counter-Strike 2 on High.

1440p

At 1440p the pair is balanced (5% CPU), so both parts are well used. Expect about 68 FPS in Cyberpunk 2077, 100 FPS in Fortnite and 236 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 RTX 3070 is the limit (23% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 32 FPS in Cyberpunk 2077, 58 FPS in Fortnite and 138 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 5600 + RTX 3070: best upgrade for this build

Upgrade the CPU first. Your Ryzen 5 5600 uses the AM4 socket, so you can drop in a faster chip without a new motherboard: Ryzen 7 5700X3D (14% CPU at 1080p, 6% GPU at 1440p) or Ryzen 7 5800X3D (11% CPU at 1080p, 9% GPU at 1440p). Update the motherboard BIOS before you swap. A faster graphics card would add little until the processor is faster. See the best CPU for the RTX 3070.

Ryzen 5 5600 + RTX 3070: power supply for this pair

The Ryzen 5 5600 can draw up to about 88 W and the RTX 3070 about 220 W. With 100 W for the rest of the system and 25% headroom, a good 550 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 5600 + RTX 3070: 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 5600 + RTX 3070: frequently asked questions

Does the Ryzen 5 5600 bottleneck the RTX 3070?

Only at 1080p. The Ryzen 5 5600 limits the RTX 3070 by 22% at 1080p, which mostly shows in high-frame-rate games. At 1440p (5% CPU) and 4K (23% GPU) the pair is balanced, so this is a good match for a 1440p monitor.

Is the Ryzen 5 5600 good enough for the RTX 3070 at 1440p?

Yes. At 1440p the bottleneck is 5% CPU, which is in the balanced range, so you get close to the card’s full speed.

How many FPS does the Ryzen 5 5600 with the RTX 3070 get?

On High settings we estimate about 98 FPS at 1080p and 72 FPS at 1440p on average across nine demanding games, for example 68 FPS in Cyberpunk 2077 at 1440p and 140 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 5600 and RTX 3070?

About 550 W from a good brand with an 80 Plus Gold rating. That covers the CPU (up to about 88 W), the graphics card (about 220 W), the rest of the system and some headroom.
