Core i7-14700K + RTX 4080 Super bottleneck at 1080p, 1440p and 4K

Resolution	Bottleneck	Limiting part	What it means
1080p	23%	CPU (moderate)	The CPU often holds the card back. Free fixes help; a CPU upgrade helps more.
1440p	6%	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.

Core i7-14700K + RTX 4080 Super: what to expect at each resolution

1080p

At 1080p the CPU bottleneck is 23%, so the RTX 4080 Super will often run below full load. You will feel it most in fast multiplayer games and in 1% lows (stutter). Expect about 176 FPS in Cyberpunk 2077, 274 FPS in Fortnite and 528 FPS in Counter-Strike 2 on High.

1440p

At 1440p the pair is balanced (6% CPU), so both parts are well used. Expect about 133 FPS in Cyberpunk 2077, 196 FPS in Fortnite and 461 FPS in Counter-Strike 2 on High.

4K

At 4K the RTX 4080 Super is the limit (23% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 77 FPS in Cyberpunk 2077, 114 FPS in Fortnite and 269 FPS in Counter-Strike 2 on High.

Core i7-14700K + RTX 4080 Super: best upgrade for this build

Upgrade the CPU first. The Core i7-14700K has no faster drop-in option worth buying on its LGA1700 platform, so the next step is a new platform such as AM5 with a Ryzen 7 7800X3D or 9800X3D. A faster graphics card would add little until the processor is faster. See the best CPU for the RTX 4080 Super.

Core i7-14700K + RTX 4080 Super: power supply for this pair

The Core i7-14700K can draw up to about 253 W and the RTX 4080 Super about 320 W. With 100 W for the rest of the system and 25% headroom, a good 850 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 4080 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 4080 Super: frequently asked questions

Does the Core i7-14700K bottleneck the RTX 4080 Super?

Only at 1080p. The Core i7-14700K limits the RTX 4080 Super by 23% at 1080p, which mostly shows in high-frame-rate games. At 1440p (6% CPU) and 4K (23% 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 4080 Super at 1440p?

Yes. At 1440p the bottleneck is 6% CPU, 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 4080 Super get?

On High settings we estimate about 177 FPS at 1080p and 139 FPS at 1440p on average across nine demanding games, for example 133 FPS in Cyberpunk 2077 at 1440p and 274 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 4080 Super?

About 850 W from a good brand with an 80 Plus Gold rating. That covers the CPU (up to about 253 W), the graphics card (about 320 W), the rest of the system and some headroom.
