Counter-Strike: Global Offensive

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 3080 delivers exceptionally high frame rates in Counter-Strike: Global Offensive, a title from 2012 that remains sensitive to both processor and graphics throughput. The measured data shows that this combination is firmly in the top tier of tested systems, with performance scaling predictably across resolutions and presets.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial but not drastic, indicating a balanced system where both components contribute meaningfully. At High settings, the average FPS falls from 630.3 at 1920x1080 to 433.8 at 2560x1440, a reduction of roughly 31% when moving to 1440p. The jump to 3840x2160 brings the average down to 255.7, which is about 59% lower than the 1080p figure. This scaling pattern suggests that the RTX 3080 remains the primary limiter at higher resolutions, as the CPU has ample headroom to feed frames.

At Low settings, the resolution scaling is even more pronounced. The 1080p average of 857.7 FPS drops to 590.9 at 1440p and then to 351.1 at 4K. The percentage drop from 1080p to 4K at Low settings is approximately 59%, matching the High preset's proportional decline. This consistency across presets indicates that resolution, not graphical complexity, is the dominant factor driving the FPS reduction. The game becomes more GPU-bound as pixel count rises, which is expected given the RTX 3080's 10 GB GDDR6X memory and 320-bit bus width.

The Medium and Ultra presets follow the same trajectory. Medium goes from 728.5 at 1080p to 501.1 at 1440p and 293.8 at 4K, while Ultra drops from 539 at 1080p to 370.1 at 1440p and 217.8 at 4K. The Ultra 4K figure of 217.8 FPS remains well above the 144 Hz refresh rate common in competitive displays, meaning even the most demanding settings stay playable at high refresh rates.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor from the Raptor Lake architecture, built on Intel's 10 nm process. Its base clock of 2.50 GHz boosts up to 4.60 GHz, providing strong single-thread performance that is critical for Counter-Strike: Global Offensive's engine. The processor's benchmark results confirm its capability: a 3DMark single-thread score of 960 and a Cinebench R23 single-core score of 3004 place it well above average, with a percentile rank of 82 against all CPUs.

In this game, the CPU's role is most evident at 1080p with lower graphical presets. The Low preset at 1080p achieves 857.7 FPS, which is likely approaching the ceiling of what the game engine can produce with this processor. The fact that dropping from High to Low at 1080p yields an increase from 630.3 to 857.7 FPS—a gain of about 36%—shows that the CPU can push substantially more frames when the GPU is less burdened. However, the i5-13400F's 20 MB of shared L3 cache and 16 threads ensure that even at 4K Ultra, the processor is not the bottleneck, as the FPS remains above 200.

The CPU's multi-threaded performance, with a Cinebench R23 multi-core score of 21279, is more than sufficient for CS:GO's typically light thread utilization. The nearest rivals in the CPU benchmark data are the Intel Core i7-13620H with an average score of 25201 (0.1% delta) and the AMD Ryzen 5 5600X3D at 25365 (-0.5% delta). These deltas are negligible, meaning the i5-13400F performs essentially on par with those chips in general compute tasks, though CS:GO's specific demands may favor the higher boost clock of the i5.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, manufactured on Samsung's 8 nm process. Its 10 GB of GDDR6X memory operates at 19 Gbps effective, delivering 760.3 GB/s of bandwidth across a 320-bit interface. The GPU's boost clock of 1710 MHz supports 8704 shading units, which drive the 29.77 TFLOPS of FP32 compute. These specifications place the RTX 3080 in the 80th percentile of all GPUs according to the benchmark data.

In CS:GO, the GPU's role becomes more pronounced at higher resolutions. The 4K Ultra setting of 217.8 FPS versus the 1080p Ultra of 539 FPS shows a 60% reduction, which is larger than the CPU-bound scenario at Low settings. This indicates that at 4K, the RTX 3080's fill rate and memory bandwidth are being exercised more heavily. The GPU's pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are sufficient to handle the game's relatively simple geometry, but the pixel count at 4K still creates a measurable load.

The RTX 3080's nearest rivals in the GPU benchmark data include the AMD Radeon RX 7900 GRE with an average score of 36101 (a delta of -0.9%) and the NVIDIA GeForce RTX 5070 Ti Mobile at 35435 (1% delta). The RTX 3080's average benchmark score of 35787 sits between these, showing that it remains competitive with newer hardware in synthetic tests. In CS:GO, the measured FPS at 1440p High of 433.8 suggests the GPU is not the limiting factor at that resolution, as the CPU can still feed frames efficiently.

How This Combo Ranks

The combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 3080 achieves a rank of 502 out of 1605 tested combos in Counter-Strike: Global Offensive. This places it in the 69th percentile of all combinations, meaning roughly a third of tested systems perform better. Given that CS:GO is a highly competitive esports title where frame rates above 300 are common, this ranking reflects the system's ability to maintain high averages, but also shows that there are faster configurations available.

The rank is influenced by both components. The CPU's percentile of 82 suggests it is stronger relative to other processors than the GPU's percentile of 80, but the combo rank of 502/1605 indicates that the pairing is well-matched. Systems ranked higher likely use more powerful GPUs like the RTX 3090 or newer RTX 40-series cards, or CPUs with higher boost clocks, but the data shows this combo still delivers playable frame rates at every resolution and preset tested. The 4K Ultra average of 217.8 FPS is particularly notable, as it exceeds the refresh rate of most 4K monitors, making this a viable 4K competitive setup.

Settings Recommendations

The measured data indicates that the optimal balance of visual quality and frame rate depends on the target resolution. At 1080p, all presets deliver frame rates well above 500 FPS, with Low reaching 857.7 FPS. For competitive play on a 144 Hz or 240 Hz monitor, the High preset at 1080p provides 630.3 FPS, which is more than sufficient and offers better visual clarity than Low. The Ultra preset at 539 FPS remains viable, but the difference between High and Ultra is minimal in terms of competitive advantage.

At 1440p, the Medium preset achieves 501.1 FPS, while High drops to 433.8 FPS. For players with 1440p 144 Hz displays, the High preset is recommended, as it stays well above the refresh rate and provides improved rendering quality. The Ultra preset at 370.1 FPS is also playable, but the FPS drop from Medium to Ultra is about 26%, which may be noticeable in fast-paced scenarios.

At 4K, the situation changes. The Low preset averages 351.1 FPS, while High drops to 255.7 FPS and Ultra to 217.8 FPS. For 4K 120 Hz displays, the High preset is the best choice, as it exceeds 120 FPS with a comfortable margin. The Ultra preset at 217.8 FPS is still above 144 Hz, making it acceptable for high-refresh 4K monitors, but the Medium preset at 293.8 FPS offers a safer buffer. Given that CS:GO is not visually demanding, the Medium preset at 4K provides a strong balance, delivering 293.8 FPS while maintaining reasonable visual fidelity. The data suggests that for most users, the High preset at any resolution offers the best experience, as it consistently delivers frame rates that exceed typical monitor refresh rates without the substantial FPS penalty of Ultra.
