THE SHORT ANSWER

The Intel Core i7-10700K + NVIDIA GeForce RTX 4070 Super pairing is rated Grade A for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 8% CPU-bound, 1440p: 3% CPU-bound, 4K: balanced. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.

Plain-English breakdown.

What this pairing actually means when you sit down to play.

The Intel Core i7-10700K + NVIDIA GeForce RTX 4070 Super pair is 3% CPU-limited at 1440p. That story changes at other resolutions — see the breakdown below. As a build, it grades high-end (A).

Expect around 310 FPS in League of Legends and ~85 in the more demanding Hogwarts Legacy — both at 1440p with high or ultra presets. Resolution matters more than most calculators show — the same parts give different verdicts at 1080p, 1440p, and 4K because GPU work scales with pixel count while CPU work is roughly fixed per frame.

If you upgrade the cpu, the Intel Core i9-11900K is an option to consider — check the compatibility notes and historical pricing below before buying. Plan on at least a 650W PSU — that includes headroom for transient spikes on the NVIDIA GeForce RTX 4070 Super.

The same pair gives a different answer at 1080p, 1440p, and 4K.

Higher resolutions push work onto the GPU — watch the balance shift.

Common questions.

Straight answers for the Intel Core i7-10700K + NVIDIA GeForce RTX 4070 Super.

  • Can the Intel Core i7-10700K run the NVIDIA GeForce RTX 4070 Super?

    Yes, the Intel Core i7-10700K will run the NVIDIA GeForce RTX 4070 Super, but it's the limiting part — at 1440p the pair is 3% CPU-bound, so the Intel Core i7-10700K can't fully feed the NVIDIA GeForce RTX 4070 Super and you'll leave some frames on the table (most noticeable at 1080p and high-refresh). The swap suggestions below list CPUs that unlock more of the NVIDIA GeForce RTX 4070 Super.

  • Will the NVIDIA GeForce RTX 4070 Super bottleneck the Intel Core i7-10700K?

    The Intel Core i7-10700K + NVIDIA GeForce RTX 4070 Super pairing is rated Grade A for 1440p gaming with a recommended 650W PSU. Resolution-by-resolution: 1080p: 8% CPU-bound, 1440p: 3% CPU-bound, 4K: balanced. CPU and GPU bottleneck verdicts depend on resolution — a pairing that is CPU-bound at 1080p is often perfectly balanced at 4K because the GPU does more work per frame as pixel count increases.

  • What PSU do I need for a Intel Core i7-10700K + NVIDIA GeForce RTX 4070 Super build?

    For a Intel Core i7-10700K (125W TDP) paired with a NVIDIA GeForce RTX 4070 Super (220W TDP), we recommend a 650W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
