Core Ultra 7 265K + RTX 5070 Ti: what to expect at each resolution

1080p

At 1080p the CPU bottleneck is 20%, so the RTX 5070 Ti will often run below full load. You will feel it most in fast multiplayer games and in 1% lows (stutter). Expect about 171 FPS in Cyberpunk 2077, 252 FPS in Fortnite and 549 FPS in Counter-Strike 2 on High.

1440p

At 1440p the pair is balanced (1% CPU), so both parts are well used. Expect about 122 FPS in Cyberpunk 2077, 180 FPS in Fortnite and 424 FPS in Counter-Strike 2 on High.

4K

At 4K the RTX 5070 Ti is the limit (26% GPU), which is normal and means you are getting the card’s full speed, unlike at 1080p. Expect about 71 FPS in Cyberpunk 2077, 105 FPS in Fortnite and 248 FPS in Counter-Strike 2 on High.

Core Ultra 7 265K + RTX 5070 Ti: best upgrade for this build

Upgrade the graphics card when you are ready. The Core Ultra 7 265K can feed a faster card: for example the RTX 5080 stays balanced at 1440p (7% CPU) and adds about 17% FPS there. Going much faster than that pushes the bottleneck onto the CPU. See the best GPU for the Core Ultra 7 265K for the full list.

Core Ultra 7 265K + RTX 5070 Ti: power supply for this pair

The Core Ultra 7 265K can draw up to about 250 W and the RTX 5070 Ti about 300 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 Ultra 7 265K + RTX 5070 Ti: 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 Ultra 7 265K + RTX 5070 Ti: frequently asked questions

Does the Core Ultra 7 265K bottleneck the RTX 5070 Ti?

Only at 1080p. The Core Ultra 7 265K limits the RTX 5070 Ti by 20% at 1080p, which mostly shows in high-frame-rate games. At 1440p (1% CPU) and 4K (26% GPU) the pair is balanced, so this is a good match for a 1440p monitor.

Is the Core Ultra 7 265K good enough for the RTX 5070 Ti at 1440p?

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

How many FPS does the Core Ultra 7 265K with the RTX 5070 Ti get?

On High settings we estimate about 172 FPS at 1080p and 130 FPS at 1440p on average across nine demanding games, for example 122 FPS in Cyberpunk 2077 at 1440p and 252 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 Ultra 7 265K and RTX 5070 Ti?

About 850 W from a good brand with an 80 Plus Gold rating. That covers the CPU (up to about 250 W), the graphics card (about 300 W), the rest of the system and some headroom.
