Core Ultra 7 265K + 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 GPU's frame-rate ceiling in this game, combined. Settings: Highest settings (TechPowerUp RTX 5090 review suite), Ryzen 7 9800X3D. CPU ceiling measured at 1080p, highest settings (TechPowerUp CPU suite), RTX 5090.

1080p

Balanced pairing

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

CPU Core Ultra 7 265Kceiling ~563 fps on its own

GPU RTX 4090ceiling ~623 fps on its own

The two measured ceilings sit within 9.7% of each other — neither part wastes much of the other.

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: 451–451 fps (measured range across sources).

CPU Core Ultra 7 265Kceiling ~563 fps on its own

GPU RTX 4090ceiling ~451 fps on its own

The GPU side is lower by about 19.8%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

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: 229–229 fps (measured range across sources).

CPU Core Ultra 7 265Kceiling ~563 fps on its own

GPU RTX 4090ceiling ~229 fps on its own

The GPU side is lower by about 59.4%: the pair runs at the lower ceiling, and upgrading the other part alone would not raise it.

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.
