Ryzen 9 9900X + RTX 4080 in Elden Ring

Every figure below is a measurement aggregated from published review charts — the CPU's frame-rate ceiling and the GPU's frame-rate ceiling in this game, combined. 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: 155–155 fps (measured range across sources).

CPU Ryzen 9 9900Xceiling ~155 fps on its own
GPU RTX 4080ceiling ~198 fps on its own

The CPU side is lower by about 21.6%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

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: 155–155 fps (measured range across sources).

CPU Ryzen 9 9900Xceiling ~155 fps on its own
GPU RTX 4080ceiling ~176 fps on its own

The two measured ceilings sit within 12.0% of each other — neither part wastes much of the other.

That range justifies a 144 Hz monitor in this game.

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

4K

Mild GPU limit

Expected frame rate: 105–105 fps (measured range across sources).

CPU Ryzen 9 9900Xceiling ~155 fps on its own
GPU RTX 4080ceiling ~105 fps on its own

The GPU side is lower by about 32.2%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

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.
