Counter-Strike: Global Offensive

Counter-Strike: Global Offensive is a notoriously CPU-bound title, and the measured results for the Intel Core i5-9400 with the NVIDIA GeForce RTX 5060 confirm that dynamic, but with an interesting twist. At 1080p, the frame rates are astronomical, but the scaling to 4K reveals where the bottleneck shifts. The data indicates this is a pairing that can push far beyond the refresh rates of most monitors, but the way performance degrades as resolution climbs tells a clear story about the balance between the six-core processor and the Blackwell-based graphics card.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, which is expected, but the percentages reveal the limiting factor. At High settings, the average frame rate falls from 501.9 FPS at 1920x1080 to 345.0 FPS at 2560x1440, a reduction of roughly 31%. Moving to 4K (3840x2160) drops the average further to 207.2 FPS, which is a 59% decline from the 1080p figure. This heavy scaling indicates that the graphics card is becoming the primary constraint at higher resolutions, as the CPU has more headroom to feed frames.

The pattern holds across all settings presets. On Low settings, the 1080p result is 687.6 FPS, falling to 473.0 FPS at 1440p and 281.8 FPS at 4K. The gap between 1080p and 4K on Low is a 59% drop, identical to High. This consistency suggests that the RTX 5060 is the scaling bottleneck; if the CPU were the limit, the percentage drop would be less severe when lowering graphical load. Specifically, at 4K, the difference between Low (281.8 FPS) and Ultra (177.9 FPS) is substantial, which is a classic sign of GPU-bound performance. At 1080p, the difference between Low (687.6 FPS) and Ultra (433.2 FPS) is also large, but the absolute numbers are so high that the CPU is still managing to keep up, though the spread suggests it is starting to feel the strain.

The data shows that 1440p is the sweet spot for this combination. The drop from 1080p is significant, but the performance remains far above what any current high-refresh monitor needs. At 4K, the frame rates are still playable and competitive, but the scaling shows that the RTX 5060 is working much harder, and the i5-9400 is no longer the primary driver of performance. The game becomes increasingly GPU-limited as resolution increases, which is a practical consideration for those with 4K displays.

FAQ

Q: Is the Intel Core i5-9400 holding back the RTX 5060 in this game?

A: At 1080p, the CPU is likely the limiting factor, as the low settings produce 687.6 FPS, but the scaling to 4K (281.8 FPS on Low) shows the GPU taking over. The CPU has a 50th percentile ranking among all CPUs, while the GPU sits at the 73rd percentile, which supports the notion that the processor is the weaker link at lower resolutions.

Q: What is the best resolution to use for competitive play?

A: For maximum frame rates, 1920x1080 is the clear choice, delivering 501.9 FPS on High settings. If you prefer higher fidelity, 2560x1440 on High still provides 345.0 FPS, which is well above the threshold for most high-refresh monitors, making it a viable alternative.

Q: How does the RTX 5060 compare to its nearest rivals in overall GPU benchmarks?

A: The RTX 5060 has an average benchmark score of 30109, which is effectively tied with the AMD Radeon RX 7700 XT (30097, 0% delta) and the AMD Radeon RX 570 (30158, -0.2% delta). It is also 0.5% ahead of the NVIDIA Tesla M60 and 0.6% ahead of the RTX 5070 Mobile.

Q: Is the game more demanding on the CPU or GPU at 4K?

A: The data indicates the GPU is the bottleneck at 4K. The average frame rate on High settings drops to 207.2 FPS from 501.9 FPS at 1080p, a drastic reduction that aligns with the GPU's increased workload. The CPU has fewer frames to prepare, making the graphics card the limiting component.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: At 2560x1440, Low settings yield 473.0 FPS, which drops to 294.0 FPS on Ultra. This is a 38% reduction in performance from the lowest to the highest preset, showing that the visual fidelity of Ultra comes at a significant cost, though the absolute numbers remain high.

Q: How does the i5-9400's CPU benchmark score compare to its closest rival?

A: The i5-9400 has an average benchmark score of 2305. The Intel Core i3-10305 (2300) is 0.2% slower, and the Intel Xeon E-2134 (2295) is 0.4% slower. The Intel Core i7-8809G (2319) is 0.6% faster.

Settings Recommendations

The measured data suggests that the High preset provides the best balance of visual quality and raw performance for this combo. At 1080p, High delivers 501.9 FPS, which is only 14% lower than the Low preset's 687.6 FPS but offers a significantly better visual experience. At 1440p, High yields 345.0 FPS, which is still far beyond what any standard 144Hz or 240Hz monitor can display. While Ultra provides a marginal visual upgrade, the cost at 1440p (294.0 FPS) and 4K (177.9 FPS) is a noticeable drop in frame rate. For a competitive shooter like CS:GO, the High preset is the rational choice, as it keeps the frame rate high enough to minimize input lag while providing a clear image.

For players with 4K displays, the Medium preset is the recommended compromise. It produces 239.1 FPS at 3840x2160, which is 15% faster than High (207.2 FPS) and 34% faster than Ultra (177.9 FPS). The drop from Medium to High at 4K is significant, suggesting that High settings on 4K push the GPU's 8GB of VRAM and memory bandwidth harder, making Medium the performance-per-frame sweet spot. Using Low settings at any resolution is generally unnecessary, as the performance gains are not worth the loss of visual clarity, particularly at 1080p where the difference between Low (687.6 FPS) and High (501.9 FPS) is less impactful than the graphical fidelity loss.

How This Combo Ranks

The combination of the Intel Core i5-9400 and the NVIDIA GeForce RTX 5060 ranks 771st out of 1605 tested combos for Counter-Strike: Global Offensive. This places it in the middle of the pack, which is a surprising result given the high absolute frame rates. The ranking suggests that while this pairing produces very playable performance, many other CPU-GPU combinations are capable of even higher frame rates, particularly those with newer, higher-clocked processors. The i5-9400's 50th percentile ranking among all CPUs is a likely contributor to this mid-tier position, as the processor's six cores and six threads (without hyper-threading) may not be feeding the GPU as efficiently as more modern chips in the CPU-bound 1080p scenarios.

The GPU's strong performance relative to its peers (73rd percentile) does not fully compensate for the CPU's average standing. The data indicates that the RTX 5060 is capable of far higher frame rates if paired with a stronger processor, as evidenced by the massive frame counts at 1080p Low (687.6 FPS) which are still not enough to top the rankings. This combo is a solid mid-pack performer, but the ranking reflects that it is not an optimal pairing for chasing the absolute top-end frame rates in CS:GO, where the CPU's single-core performance is often the deciding factor.

GPU Role

The NVIDIA GeForce RTX 5060 plays a crucial role in this game's performance, particularly as resolution and settings increase. The GPU is built on the Blackwell 2.0 architecture with a 5 nm process node and features 8 GB of GDDR7 memory on a 128-bit bus, providing a memory bandwidth of 448.0 GB/s. The base clock is 2280 MHz with a boost clock of 2497 MHz, and the card has a TDP of 145 W. In CS:GO, the GPU's role is secondary at 1080p, where the CPU is the primary driver, but it becomes the dominant factor at 4K, where the average FPS on High settings is 207.2, a 59% drop from 1080p.

The 8 GB VRAM capacity is sufficient for CS:GO at all settings, as the game is not VRAM-intensive. However, the memory bandwidth and clock speeds determine how well the card scales with resolution. The data shows that at 4K, the difference between Low (281.8 FPS) and Ultra (177.9 FPS) is 103.9 FPS, which is a 37% reduction. This scaling suggests that the GPU's processing power, not its memory capacity, is the limiting factor at higher resolutions. The RTX 5060's performance is comparable to the AMD Radeon RX 7700 XT (0% delta) and the AMD Radeon RX 570 (-0.2% delta) in general benchmarks, but in this specific game, the data shows it provides ample power for high-refresh gaming at 1080p and 1440p, with playable frame rates at 4K.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across all resolutions and settings. At 1920x1080, the Low preset produces the highest average frame rate at 687.6 FPS, followed by Medium at 584.1 FPS, High at 501.9 FPS, and Ultra at 433.2 FPS. At 2560x1440, the order remains the same, with Low at 473.0 FPS, Medium at 402.3 FPS, High at 345.0 FPS, and Ultra at 294.0 FPS. At 3840x2160, Low yields 281.8 FPS, Medium produces 239.1 FPS, High delivers 207.2 FPS, and Ultra drops to 177.9 FPS.

The scaling from 1080p to 4K is consistent across all presets, with an average drop of approximately 59% from the 1080p value to the 4K value. For example, High settings fall from 501.9 FPS to 207.2 FPS, and Low settings fall from 687.6 FPS to 281.8 FPS. The difference between Medium and High is relatively consistent across resolutions, with High being about 13-14% slower than Medium at each resolution. The Ultra preset is the most demanding, being roughly 16% slower than High at 1080p and 1440p, and 14% slower at 4K. These numbers indicate that the RTX 5060 has enough headroom to handle the most demanding settings at 1440p, but the i5-9400's limitations become apparent at 1080p where the frame rates are extremely high.
