Common questions.

Straight answers for the Intel Core i7-10700K + NVIDIA GeForce RTX 4090.

• Can the Intel Core i7-10700K run the NVIDIA GeForce RTX 4090?

  +

  Yes, the Intel Core i7-10700K will run the NVIDIA GeForce RTX 4090, but it's the limiting part — at 1440p the pair is 5% CPU-bound, so the Intel Core i7-10700K can't fully feed the NVIDIA GeForce RTX 4090 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 4090.

• Will the NVIDIA GeForce RTX 4090 bottleneck the Intel Core i7-10700K?

  +

  The Intel Core i7-10700K + NVIDIA GeForce RTX 4090 pairing is rated Grade S for 1440p gaming with a recommended 1050W PSU. Resolution-by-resolution: 1080p: 8% CPU-bound, 1440p: 5% CPU-bound, 4K: 2% CPU-bound. 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 4090 build?

  +

  For a Intel Core i7-10700K (125W TDP) paired with a NVIDIA GeForce RTX 4090 (450W TDP), we recommend a 1050W power supply at minimum. This includes 40% headroom over the parts' combined TDP plus 100W for the motherboard, RAM, fans, and storage.
