Core i7-14700K + RTX 4070 Super: what to expect at each resolution

1080p

At 1080p the CPU bottleneck is 16%, so the RTX 4070 Super will often run below full load. You will feel it most in fast multiplayer games and in 1% lows (stutter). Expect about 136 FPS in Cyberpunk 2077, 201 FPS in Fortnite and 473 FPS in Counter-Strike 2 on High.

1440p

At 1440p the RTX 4070 Super is the limit (4% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 97 FPS in Cyberpunk 2077, 143 FPS in Fortnite and 338 FPS in Counter-Strike 2 on High.

4K

At 4K the RTX 4070 Super is the limit (29% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 57 FPS in Cyberpunk 2077, 84 FPS in Fortnite and 197 FPS in Counter-Strike 2 on High.

Core i7-14700K + RTX 4070 Super: best upgrade for this build

Upgrade the graphics card when you are ready. The Core i7-14700K can feed a faster card: for example the RTX 5080 stays balanced at 1440p (9% CPU) and adds about 43% FPS there. Going much faster than that pushes the bottleneck onto the CPU. See the best GPU for the Core i7-14700K for the full list.

Core i7-14700K + RTX 4070 Super: power supply for this pair

The Core i7-14700K can draw up to about 253 W and the RTX 4070 Super about 220 W. With 100 W for the rest of the system and 25% headroom, a good 750 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.

Core i7-14700K + RTX 4070 Super: 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.

Core i7-14700K + RTX 4070 Super: frequently asked questions

Does the Core i7-14700K bottleneck the RTX 4070 Super?

Only at 1080p. The Core i7-14700K limits the RTX 4070 Super by 16% at 1080p, which mostly shows in high-frame-rate games. At 1440p (4% GPU) and 4K (29% GPU) the pair is balanced, so this is a good match for a 1440p monitor.

Is the Core i7-14700K good enough for the RTX 4070 Super at 1440p?

Yes. At 1440p the bottleneck is 4% GPU, which is in the balanced range, so you get close to the card’s full speed.

How many FPS does the Core i7-14700K with the RTX 4070 Super get?

On High settings we estimate about 142 FPS at 1080p and 105 FPS at 1440p on average across nine demanding games, for example 97 FPS in Cyberpunk 2077 at 1440p and 201 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 Core i7-14700K and RTX 4070 Super?

About 750 W from a good brand with an 80 Plus Gold rating. That covers the CPU (up to about 253 W), the graphics card (about 220 W), the rest of the system and some headroom.
