Counter-Strike 2

Counter-Strike 2 presents an interesting scaling pattern for the Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3080, one that clearly delineates where the bottleneck shifts as pixel count rises. At 1080p, the frame rates are astronomically high, with the Low preset hitting 503.6 FPS and Medium reaching 418.1 FPS. Dropping to High yields 313.8 FPS, while Ultra still maintains a robust 242.6 FPS. The delta from Low to Ultra at 1080p is a 51.8% reduction in frame rate, which is substantial, yet the absolute numbers remain so high that the limiting factor is almost certainly the CPU. Moving to 1440p, the pattern holds but with a slight compression: Low produces 333.1 FPS, Medium 279.2 FPS, High 207.7 FPS, and Ultra 158.7 FPS. The gap between Low and Ultra narrows to a 52.3% drop, which is similar to 1080p, but the overall reduction in FPS from 1080p to 1440p at the same settings (e.g., High drops from 313.8 to 207.7, a 33.8% decrease) indicates the GPU is beginning to matter more. At 4K, the scaling becomes dramatic and reveals a GPU-bound scenario. High drops to 116 FPS, Medium to 154 FPS, Low to 186 FPS, and Ultra to 90.7 FPS. The delta from Low to Ultra at 4K is a 51.2% reduction, but the absolute numbers now sit in a range where the RTX 3080's pixel throughput is the primary governor. The data implies that the CPU has ample headroom at 4K, as the FPS drop from 1440p to 4K at Low settings (333.1 to 186, a 44.2% decrease) is more severe than the GPU's raw compute scaling would suggest, pointing to a pure resolution-driven load.

Resolution Scaling

The measured FPS data reveals a clear narrative about component utilization across resolutions. At 1920x1080, the i5-12400F and RTX 3080 combination produces results that are so high that they exceed the refresh rates of most gaming monitors. The Low preset's 503.6 FPS and Medium's 418.1 FPS are figures that suggest the CPU's six cores, running at a boost clock of 4.40 GHz, are the primary driver, as the GPU has minimal work per frame. The 1080p Ultra result of 242.6 FPS is still exceptionally high, but the progression from Low to Ultra shows a consistent penalty, indicating that even at lower resolutions, the graphics settings do impose a load on the system. However, the fact that 1080p High (313.8 FPS) is faster than 4K Low (186 FPS) by 68.7% highlights how resolution, not just preset, dictates the workload.

At 2560x1440, the data shows a transition zone. The 1440p Low result of 333.1 FPS is still CPU-bound, but the 1440p Ultra result of 158.7 FPS is significantly lower than the 1080p Ultra of 242.6 FPS, a 34.6% drop. This indicates that the RTX 3080, with its 10 GB of GDDR6X memory and 760.3 GB/s bandwidth, is starting to feel the pressure of increased pixel count. The scaling from 1440p High (207.7 FPS) to 4K High (116 FPS) is a 44.1% reduction, which is a steeper decline than the resolution change alone would account for if the system were purely CPU-limited. This suggests that at 1440p, the balance is shifting, and by 4K, the GPU is unequivocally the limiting component. The 4K results, ranging from 186 FPS on Low to 90.7 FPS on Ultra, show that the RTX 3080's 8704 shading units are being fully exercised, with the game's visual complexity at Ultra creating a workload that pushes the GPU to its limits.

Settings Recommendations

Examining the measured rows, the optimal balance of visual fidelity and frame rate appears to lie within the High preset for most resolutions. At 1080p, High produces 313.8 FPS, which is 71.2 FPS lower than Medium (418.1 FPS) but still far above any practical refresh rate ceiling. The jump from High to Ultra at 1080p costs 71.2 FPS (313.8 to 242.6), which is a 22.7% performance penalty for what is often a marginal visual gain in a competitive FPS. At 1440p, High delivers 207.7 FPS, which is a 49.0 FPS improvement over Ultra's 158.7 FPS. This makes High the clear choice for high-refresh-rate 1440p displays, as the data shows it retains a significant FPS advantage over Ultra while offering most of the visual features. For 4K, the decision becomes more nuanced. High yields 116 FPS, while Medium yields 154 FPS, a 32.8% difference. Given that 4K displays are typically 60 Hz or 120 Hz, the Medium preset's 154 FPS ensures a smoother experience than High's 116 FPS, which could dip closer to the refresh rate limit in busy scenes. The Low preset at 4K (186 FPS) is viable for maximum frame rate, but the visual compromise is substantial. The data suggests that for competitive play, High at 1080p or 1440p is the sweet spot, while for 4K, Medium offers the best experience per the measured rows, balancing image quality and the GPU's capabilities.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across twelve distinct configurations. At 1920x1080, the results are as follows: Low settings produce an average of 503.6 FPS, Medium yields 418.1 FPS, High delivers 313.8 FPS, and Ultra drops to 242.6 FPS. The progression from Low to Ultra shows a consistent and significant penalty, with the Ultra preset being 51.8% slower than Low. Moving to 2560x1440, the averages are 333.1 FPS for Low, 279.2 FPS for Medium, 207.7 FPS for High, and 158.7 FPS for Ultra. The relative difference between Low and Ultra at 1440p is 52.3%, mirroring the 1080p scaling. At 3840x2160, the results are 186 FPS for Low, 154 FPS for Medium, 116 FPS for High, and 90.7 FPS for Ultra. The 4K Ultra result is the lowest in the entire dataset, and the gap between Low and Ultra at 4K is 51.2%, a similar percentage reduction as in other resolutions, but the absolute numbers are now in a range where frame pacing and GPU load are critical. The data also shows that increasing resolution from 1080p to 4K at the same preset has a massive impact: for High settings, the FPS drops from 313.8 to 116, a 63.0% reduction; for Medium, it drops from 418.1 to 154, a 63.2% reduction; for Low, it drops from 503.6 to 186, a 63.1% reduction; and for Ultra, it drops from 242.6 to 90.7, a 62.6% reduction. This consistent ~63% drop across all presets when moving from 1080p to 4K strongly indicates that the RTX 3080's performance scaling with pixel count is the dominant factor, as the CPU's workload remains relatively constant.

GPU Role

The NVIDIA GeForce RTX 3080 plays a decisive role in determining the frame rates, particularly at higher resolutions and settings. Its specifications include 10 GB of GDDR6X memory on a 320-bit bus, delivering a bandwidth of 760.3 GB/s. The GPU's boost clock is rated at 1710 MHz, with a base clock of 1440 MHz. In Counter-Strike 2, the 4K results show that the GPU's memory bandwidth and shading power are critical. The Ultra preset at 4K, which averages 90.7 FPS, is likely constrained by the 8704 shading units and the 96 ROPs, as the game's visual effects at this level demand significant pixel throughput. The data shows that the RTX 3080's performance is not the limiting factor at 1080p, where the CPU dominates, but as resolution increases, the GPU's role becomes paramount. The 4K Low result of 186 FPS, while high, is still 44.2% lower than the 1440p Low result, proving that the GPU is the primary bottleneck at 4K regardless of settings. The GPU's 10 GB frame buffer appears sufficient for the game's textures at all presets, as there are no anomalies in the scaling that would indicate memory capacity issues. The benchmarks place this GPU in the 80th percentile of all GPUs, with an average benchmark score of 35787, and its nearest rival, the AMD Radeon RX 7900 GRE, is only 0.9% faster in aggregate benchmarks, yet the game's FPS data shows how workload-specific performance can differ from synthetic scores.

CPU Role

The Intel Core i5-12400F's role in this combination is primarily to feed the GPU with enough data at lower resolutions. With 6 cores and 12 threads, a base clock of 2.50 GHz, and a boost clock of 4.40 GHz, this Alder Lake processor provides substantial single-thread performance, which is critical for Counter-Strike 2's engine. The 18 MB of shared L3 cache also helps in keeping frequently accessed data close to the cores. The benchmark results show that at 1080p, the CPU is the limiting factor, as evidenced by the 503.6 FPS on Low settings, which is a figure that the GPU could theoretically exceed if it were not constrained by the CPU's frame generation rate. The CPU's single-thread score in Cinebench R23 is 2332, and its Passmark single-thread score is 3481, indicating strong performance per core. The data implies that the CPU's maximum frame rate ceiling in this game is likely around 500 FPS, as the 1080p Low and Medium results (503.6 and 418.1 FPS) show the CPU is working near its limit, while the GPU is underutilized. At 1440p and 4K, the CPU's role diminishes, as the GPU takes over as the bottleneck. However, the CPU must still maintain a high enough frame rate to avoid dropping below the GPU's output. The 4K Low result of 186 FPS confirms that the CPU can easily sustain this level, as it is far below the 1080p ceiling. The CPU's nearest rival, the Intel Core i7-8700K, has a nearly identical average benchmark score (19210 vs 19221), but the i5-12400F's newer architecture likely provides better per-clock performance, which is beneficial in a game like Counter-Strike 2 where frame pacing is crucial.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the Intel Core i5-12400F and NVIDIA GeForce RTX 3080 achieves a rank of 499 out of 1632 combos in Counter-Strike 2. This places it in the top 30.6% of all tested configurations, which is a strong showing given that the CPU is a mid-range part from 2022 and the GPU is from the previous generation. The rank suggests that the combination is well-balanced for this game, with the CPU's high single-thread performance complementing the GPU's raw power. The fact that it ranks in the upper third indicates that many higher-end CPUs (like the i7-8700K, which is 0.1% faster in aggregate benchmarks) or newer GPUs (like the RTX 5070 Ti Mobile, which is 1% faster in aggregate benchmarks) do not necessarily translate to significantly better in-game performance, as the game is likely sensitive to both CPU and GPU, but not overly dependent on the absolute extremes of either. The rank of 499 also implies that there is a long tail of combinations that perform worse, which positions this setup as a capable choice for high-refresh-rate 1080p and 1440p gaming, as well as playable 4K. The data shows that this combo's performance is more than adequate for competitive play, where frame rates above 200 FPS are often desired, and it achieves that at 1440p on High settings (207.7 FPS). The rank reflects the synergy between the CPU's 4.40 GHz boost clock and the GPU's 1710 MHz boost clock, which together produce the measured FPS figures. It is important to note that this rank is specific to Counter-Strike 2, and the same combo may rank differently in other titles, but within this game, the data indicates a robust and competitive configuration.
