Core i9-12900K + RTX 5070 in Elden Ring

Every figure below is a measurement aggregated from published review charts — the CPU's frame-rate ceiling and the frame rate the GPU delivers in this game, combined. The CPU figure is the highest frame rate that CPU sustained in this game with a flagship GPU installed — past that frame rate, the CPU is the limit. Settings: Highest settings (TechPowerUp RTX 5090 review suite), framerate cap removed - the shipped game caps at 60 fps. CPU ceiling measured at 1080p, highest settings (TechPowerUp CPU suite), RTX 4090, framerate cap removed.

1080p

Mild CPU limit

Expected frame rate: 147–147 fps (measured range across sources).

CPU Core i9-12900Kceiling ~147 fps on its own

GPU RTX 5070delivers ~189 fps in this game at 1080p

The CPU side is lower by about 22.6% in this game at 1080p. The math, from the two measured figures above: the pair runs at the lower one (~147 fps), and the gap to the faster side is (189 − 147) ÷ 189 ≈ 22.6% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — the same two parts score differently in another game, which is why no universal bottleneck percentage exists for a pair of parts. Upgrading the faster part alone would not raise the frame rate.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

1440p

Balanced pairing

Expected frame rate: 147–147 fps (measured range across sources).

CPU Core i9-12900Kceiling ~147 fps on its own

GPU RTX 5070delivers ~154 fps in this game at 1440p

The CPU ceiling and the GPU's delivered rate sit within 4.6% of each other — neither part wastes much of the other. The gap is measured between the two figures above: (faster − slower) ÷ faster.

That range justifies a 144 Hz monitor in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.

4K

Strong GPU limit

Expected frame rate: 89–89 fps (measured range across sources).

CPU Core i9-12900Kceiling ~147 fps on its own

GPU RTX 5070delivers ~89 fps in this game at 4K

The GPU side is lower by about 39.4% in this game at 4K. The math, from the two measured figures above: the pair runs at the lower one (~89 fps), and the gap to the faster side is (147 − 89) ÷ 147 ≈ 39.4% of the faster side's output. That percentage belongs to this game, this resolution and these settings only — the same two parts score differently in another game, which is why no universal bottleneck percentage exists for a pair of parts. Upgrading the faster part alone would not raise the frame rate.

That range suits a 60 Hz monitor; a high-refresh panel would be underused in this game.

Confidence: MEDIUM — based on 2 source measurements for these two parts.
