Counter-Strike: Global Offensive

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4080 lands at rank 241 out of 3719 tested combos in Counter-Strike: Global Offensive, placing it in the top 6.5% of all configurations. This is a formidable position for a competitive FPS, indicating that the combination is not merely playable but genuinely elite. The rank is a product of the RTX 4080’s immense raw throughput and the 8400F’s capable Zen 4 architecture, which together deliver frame rates that far exceed the requirements of even the highest-refresh-rate monitors. The data shows that this combo is built for speed, with every measured scenario producing triple-digit average FPS, ensuring that the game’s engine is almost never the bottleneck in a real-world match.

How This Combo Ranks

With a combo rank of 241 out of 3719, this pairing sits in the upper echelon of tested systems for CS:GO. This ranking is not a marginal placement; it signifies that the system outperforms the vast majority of alternatives, including many that feature newer or more expensive components. The percentile placement suggests that for a player whose primary goal is maximizing competitive frame rates, this combination is a proven, high-performance solution. The data indicates that the system’s performance is consistently high across all settings, which is a hallmark of a balanced and powerful pairing. While it does not claim the top spot, being in the 94th percentile of all tested combos means that the user is unlikely to be at a hardware disadvantage in any online lobby. The rank primarily reflects the GPU’s dominance, but the CPU’s single-thread strength ensures that the system does not suffer from the frame pacing issues that can plague lesser processors in CPU-bound titles like CS:GO.

GPU Role

The NVIDIA GeForce RTX 4080 is the undisputed performance driver in this configuration. Its 16 GB of GDDR6X memory on a 256-bit bus provides a bandwidth of 716.8 GB/s, which is more than sufficient for CS:GO’s modest texture and geometry demands. The GPU’s clocks are set to a base of 2205 MHz and a boost of 2505 MHz, and these high frequencies are the primary reason the card is able to push frame rates into the thousands at lower resolutions. The data confirms this: at 1080p Low, the combo achieves an average of 1141 FPS, a figure that is entirely GPU-limited, as the CPU cannot generate frames any faster. The card’s 9728 shading units and 304 TMUs are massive overkill for a game from 2012, but this headroom is what allows for the absurdly high 1% lows and consistent frame times. The RTX 4080’s architecture, Ada Lovelace, is built for efficiency and high throughput, which is why even at 4K Ultra, the system still manages an average of 292 FPS. In essence, the GPU is not being challenged by CS:GO; it is operating well within its comfort zone, which is ideal for maintaining maximum refresh rates without any thermal or power throttling. The benchmark results show that the GPU is the limiting factor only at the very highest settings and resolutions, and even then, it delivers performance that is several times faster than what a 144 Hz monitor can display.

Settings Recommendations

For competitive play, the measured FPS data suggests that the Low preset at any resolution is the optimal choice, but the differences are nuanced. At 1080p, the Low preset yields 1141 FPS, which is a 26% increase over the High preset’s 841 FPS. This margin can be crucial for players with 360 Hz or 500 Hz monitors, as it provides more headroom for frame time consistency. However, the Medium preset at 1080p offers 971 FPS, which is still exceptionally high and may provide better visual clarity for spotting enemies at a distance. The data shows that the jump from Medium to High at 1080p costs 130 FPS, a significant drop, while the jump from High to Ultra costs another 124 FPS. For most players, the Medium preset represents the best balance, as it retains a high average FPS (971) and includes the only recorded minimum FPS in the 1080p tier (825), suggesting better frame pacing stability than the other presets. At 1440p, the same logic applies: Medium at 668 FPS is a safer bet than High at 578 FPS, and both are far beyond what is needed for smooth gameplay. At 4K, the recommendation shifts slightly; using Low (464 FPS) is the only way to maintain a frame rate that matches a 360 Hz monitor, while Medium (395 FPS) is still excellent for 240 Hz displays. The Ultra preset at 4K (292 FPS) is the only scenario where the system dips below 300 FPS, but it is still perfectly playable on a 240 Hz panel. In summary, the data indicates that Medium is the sweet spot for a competitive edge, offering the best visual fidelity without sacrificing the frame rate headroom that matters most.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system’s performance across resolutions and settings. At 1920x1080, the average FPS ranges from 717 on Ultra to 1141 on Low. The Medium preset records an average of 971 FPS, with a minimum of 825 and a maximum of 1117, showing a tight distribution that indicates consistent performance. High settings at 1080p produce 841 FPS. Moving to 2560x1440, the numbers scale down predictably: Low averages 785 FPS, Medium 668 FPS (min 568, max 768), High 578 FPS, and Ultra 494 FPS. The 1440p Medium result is particularly notable because the minimum FPS of 568 is still higher than the 4K Ultra average, demonstrating the GPU’s ability to maintain high frame rates even when the resolution increases. At 3840x2160, the performance begins to show the strain of the higher pixel count. The Low preset averages 464 FPS, Medium averages 395 FPS (min 335, max 454), High averages 342 FPS, and Ultra averages 292 FPS. The 4K Medium minimum of 335 FPS is a critical data point; it shows that even in the most demanding scenario, the system never drops below 300 FPS, which reflects the RTX 4080’s raw power. The overall trend is that the system is so fast that the differences between presets are more about maximizing refresh rate headroom than about achieving playability. Every single data point in the pack is above 290 FPS, meaning that the system is capable of driving a 240 Hz monitor at maximum settings in 4K without any perceptible stutter.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a classic GPU-bound curve, but with a twist. At High settings, the average FPS drops from 841 at 1080p to 578 at 1440p (a 31% decrease), and then to 342 at 4K (a 59% decrease from 1080p). This scaling is steeper than what would be expected from a purely CPU-limited scenario, indicating that the RTX 4080 is increasingly becoming the bottleneck as the resolution rises. However, the CPU’s role is still significant. The fact that the system reaches 1141 FPS at 1080p Low proves that the Ryzen 5 8400F can feed the GPU with enough data to saturate it, but at 4K Ultra, the frame rate drops to 292 FPS, which is a 74% reduction from the 1080p Low figure. This suggests that the GPU is doing the heavy lifting at higher resolutions, while the CPU’s single-thread performance (as evidenced by its 3DMark single-thread score of 951) is adequate to prevent a complete collapse. The data shows that the FPS drop from 1440p to 4K at Medium settings is 41% (from 668 to 395), which is a smaller relative drop than the 46% drop from 1080p to 1440p (from 971 to 668). This non-linear scaling indicates that the system is not purely pixel-bound; the game’s engine and CPU overhead play a role at lower resolutions, while the GPU’s memory bandwidth and fill rate become the primary constraints at 4K. For a player, this means that dropping from 4K to 1440p yields a massive 74% FPS increase at High settings, making 1440p the sweet spot for those who want to push refresh rates to the absolute maximum.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. While it is not a flagship CPU, its single-thread performance is what matters most for CS:GO, which is notoriously reliant on high IPC and clock speeds. The benchmark data shows a single-thread score of 951 in 3DMark, and a Cinebench R23 single-core score of 2943, which are solid figures that place it in the 77th percentile of all CPUs. This is crucial because CS:GO’s engine is largely single-threaded, and the data confirms that the 8400F is capable of driving the RTX 4080 to its limits at lower resolutions. The CPU’s 16 MB of shared L3 cache and 1 MB of L2 cache per core help reduce memory latency, which is essential for maintaining high frame rates in fast-paced FPS games. The data shows that the CPU is not the bottleneck at 1080p, as the FPS scales directly with GPU settings changesley. For example, at 1080p, the difference between Low and Ultra is 424 FPS (1141 vs 717), which is entirely due to the GPU’s workload. However, at 4K, the FPS differences between presets are smaller (464 to 292 FPS), indicating that the GPU is becoming the limiting factor pressing against the CPU’s frame generation ceiling. The CPU’s 3DMark max-thread score of 6165 and Cinebench R20 multi-core score of 8757 show that it has ample multi-threaded headroom for background tasks, but in CS:GO, it is the 4.70 GHz boost clock that does the heavy lifting. Compared to its nearest rival, the AMD Ryzen 5 7500F, the 8400F is only 0.2% faster in average benchmark score, which is a negligible margin in real-world gaming. The data indicates that the 8400F is a well-matched companion to the RTX 4080, providing enough single-thread speed to avoid limiting the GPU at 1080p and 1440p, while the GPU takes over as the primary performance driver at 4K. The system’s overall rank of 241 is a direct result of this synergy, where the CPU’s competent IPC ensures that no frame is left on the table due to processing delays.
