Core Ultra 9 285K + RTX 5080 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

Balanced pairing

Expected frame rate: 563–563 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~600 fps on its own

GPU RTX 5080delivers ~563 fps in this game at 1080p

The CPU ceiling and the GPU's delivered rate sit within 6.1% of each other — neither part wastes much of the other. The gap is measured between the two figures above: (faster − slower) ÷ faster.

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

Mild GPU limit

Expected frame rate: 409–409 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~600 fps on its own

GPU RTX 5080delivers ~409 fps in this game at 1440p

The GPU side is lower by about 31.8% in this game at 1440p. The math, from the two measured figures above: the pair runs at the lower one (~409 fps), and the gap to the faster side is (600 − 409) ÷ 600 ≈ 31.8% 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

Strong GPU limit

Expected frame rate: 224–224 fps (measured range across sources).

CPU Core Ultra 9 285Kceiling ~600 fps on its own

GPU RTX 5080delivers ~224 fps in this game at 4K

The GPU side is lower by about 62.6% in this game at 4K. The math, from the two measured figures above: the pair runs at the lower one (~224 fps), and the gap to the faster side is (600 − 224) ÷ 600 ≈ 62.6% 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 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.
