Ryzen 5 5600X + RTX 4090 in Counter-Strike 2

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), Ryzen 7 9800X3D. CPU ceiling measured at 1080p, highest settings (TechPowerUp CPU suite), RTX 5090; Ryzen 5 5600X from Hardware Unboxed's AM4 revisit (Very High preset).

1080p

Strong CPU limit

Expected frame rate: 290–290 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~290 fps on its own

GPU RTX 4090delivers ~623 fps in this game at 1080p

The CPU side is lower by about 53.5% in this game at 1080p. The math, from the two measured figures above: the pair runs at the lower one (~290 fps), and the gap to the faster side is (623 − 290) ÷ 623 ≈ 53.5% 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 feeds a 165 Hz or faster monitor — this is high-refresh territory in this game.

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

1440p

Strong CPU limit

Expected frame rate: 290–290 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~290 fps on its own

GPU RTX 4090delivers ~451 fps in this game at 1440p

The CPU side is lower by about 35.7% in this game at 1440p. The math, from the two measured figures above: the pair runs at the lower one (~290 fps), and the gap to the faster side is (451 − 290) ÷ 451 ≈ 35.7% 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 feeds a 165 Hz or faster monitor — this is high-refresh territory in this game.

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

4K

Mild GPU limit

Expected frame rate: 229–229 fps (measured range across sources).

CPU Ryzen 5 5600Xceiling ~290 fps on its own

GPU RTX 4090delivers ~229 fps in this game at 4K

The GPU side is lower by about 21.1% in this game at 4K. The math, from the two measured figures above: the pair runs at the lower one (~229 fps), and the gap to the faster side is (290 − 229) ÷ 290 ≈ 21.1% 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 feeds a 165 Hz or faster monitor — this is high-refresh territory in this game.

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