Rust

The AMD Ryzen 5 7400F and NVIDIA GeForce RTX 5090 D combination presents a fascinating study in bottleneck dynamics within Rust. The data shows a system where the GPU is overwhelmingly dominant, yet the 1080p results hint at a ceiling imposed by the processor. This analysis breaks down the measured performance, contextualizes it against other tested combos, and answers key questions about how this pairing behaves across different settings and resolutions.

Resolution Scaling

The measured FPS data reveals a classic pattern of GPU-bound scaling as resolution increases, but with a notable twist at the lower end. Moving from 1920x1080 to 2560x1440 on the High preset, the average frame rate drops from 175 FPS to 136 FPS, a reduction of 39 FPS. This is a significant 22.3% performance hit, which is typical as the GPU takes on more pixel-rendering work. However, the jump from 2560x1440 to 3840x2160 on the same High preset is even more dramatic, with the average falling from 136 FPS to 80 FPS. This 41.2% decrease underscores the immense pixel throughput required at 4K, firmly placing the RTX 5090 D as the primary limiting factor at this resolution.

The scaling pattern changes character when examining the Low preset. At 1920x1080 Low, the combo achieves 216 FPS, but at 2560x1440 Low, it only drops to 190 FPS. This smaller 12% reduction between 1080p and 1440p, compared to the 22.3% drop on High, suggests that at Low settings, the CPU is beginning to assert its influence. The game's logic and draw calls become a larger portion of the frame time when the GPU is not heavily taxed. This hypothesis is further supported by the 4K Low result of 141 FPS. The gap between 1440p Low (190 FPS) and 4K Low (141 FPS) is a 25.8% reduction, which is substantial, but the absolute numbers remain high, indicating that even at 4K with reduced settings, the GPU is still not fully saturated.

The most telling data point for identifying the limiting component is the performance delta between Low and Ultra at each resolution. At 1920x1080, the difference between Low (216 FPS) and Ultra (150 FPS) is 66 FPS, or 30.6%. At 2560x1440, this gap widens to 87 FPS (190 vs. 103 FPS), a 45.8% difference. At 3840x2160, the gap is the largest in absolute terms: 141 FPS (Low) versus 61 FPS (Ultra), which is a 56.7% reduction. This trend clearly indicates that as resolution increases, the impact of graphical settings grows, which is the signature of a GPU-bound scenario. The CPU's role is more pronounced at 1080p, where the settings-based scaling is compressed, suggesting that the Ryzen 5 7400F is providing a performance ceiling that prevents the full range of GPU capability from being utilized.

How This Combo Ranks

Within the vast database of tested combinations, this specific pairing of the Ryzen 5 7400F and RTX 5090 D achieves a rank of 76 out of 2953 combos for Rust. This places it in the top 2.6% of all tested systems, a position that reflects the sheer power of the RTX 5090 D. The percentile ranking of the GPU itself is 92, meaning it outperforms 92% of all GPUs in the database, which heavily contributes to this combo's high placement. The CPU, with a percentile of 83, is also a strong performer, but its relative standing is lower than the GPU's, reinforcing the notion of a processor that is capable but potentially holding back the graphics card in certain scenarios.

The combo rank of 76 is impressive, but an analysis of the individual components' nearest rivals provides context. The CPU's nearest rival, the Intel Core i5-14600T, has an average benchmark score that is only 0.1% higher. Similarly, the AMD Ryzen 7 PRO 6850H is 0.2% behind. These razor-thin margins indicate that the 7400F is performing exactly as expected for its class, with no silicon lottery luck or deficit. On the GPU side, the RTX 5090 D's nearest rival, the AMD Radeon RX 6650M XT, has an average score that is 1.1% lower, while the AMD Radeon RX 6850M XT is 1.6% higher. These small deltas suggest that the 5090 D is a consistent performer relative to its peers, even though those peers are in a different market segment (mobile versus desktop). The top-76 finish is therefore a direct result of combining two top-tier parts, even if they are not perfectly balanced for every workload.

FAQ

Q: Is this combination more limited by the CPU or GPU at 1080p?

A: The data suggests the CPU is the limiting factor at 1920x1080. The frame rate difference between Low (216 FPS) and Ultra (150 FPS) is only 30.6%, which is smaller than the gaps observed at higher resolutions. This compression of scaling indicates that the Ryzen 5 7400F's processing power is the bottleneck, preventing the RTX 5090 D from fully flexing its muscles.

Q: At what resolution does the GPU become the clear bottleneck?

A: At 3840x2160, the GPU is unambiguously the limiting component. The average FPS drops from 141 at Low to 61 at Ultra, a 56.7% reduction. This massive swing in performance based on settings is the classic indicator of a GPU-bound scenario, where the graphics card's pixel and shader processing capabilities are the primary constraint.

Q: How does the 7400F's single-threaded performance relate to Rust's results?

A: Rust is known for being sensitive to single-threaded performance. The Ryzen 5 7400F's Cinebench R23 single-core score is 3072, and its Passmark single-thread score is 3689. These strong scores are likely a key reason why the combo can still achieve high frame rates like 150 FPS at 1080p Ultra, as the game's main logic thread is well-served by this processor.

Q: Given the high rank, is the RTX 5090 D being fully utilized?

A: Not at 1080p. While the combo ranks 76th out of 2953, the 1080p results indicate a CPU limitation. At 1080p High, the combo hits 175 FPS, but at 1440p High, it still manages 136 FPS. The relatively small drop from 1080p to 1440p suggests the GPU has headroom at the lower resolution that the CPU cannot feed. At 4K, the GPU is far more likely to be the limiting factor.

Q: What is the most consistent performance profile for this combo?

A: The Medium settings at 2560x1440 provide a balanced profile. It delivers an average of 161 FPS with a minimum of 136 FPS and a maximum of 185 FPS. This shows a stable frame time distribution, avoiding the extreme lows seen at 4K Ultra and avoiding the potential CPU-bound ceiling seen at 1080p.

Q: How does the combo's rank compare to the individual component percentiles?

A: The combo ranks in the top 2.6% (76/2953). The GPU alone is in the 92nd percentile, while the CPU is in the 83rd percentile. The combo's rank is higher than the CPU's individual percentile, demonstrating that the powerful GPU lifts the overall system ranking, even though the CPU is the weaker link in the chain.

Measured FPS Breakdown

The measured data provides a complete picture of performance across nine distinct scenarios.

At 1920x1080, the combo delivers its highest frame rates. The Low preset leads with an average of 216 FPS. The High preset averages 175 FPS. The Medium preset is a strong middle ground, averaging 185 FPS with a minimum of 157 and a maximum of 213 FPS, showing excellent consistency. The Ultra preset, while the most demanding, still achieves a smooth 150 FPS average.

Moving to 2560x1440, the impact of increased resolution is clear. The Low preset averages 190 FPS. The High preset drops to 136 FPS. The Medium preset provides an average of 161 FPS, with a minimum of 136 FPS and a maximum of 185 FPS, maintaining good playability. The Ultra preset falls to an average of 103 FPS, which is still a solid experience for a 1440p panel.

At 3840x2160, the RTX 5090 D is truly put to work. The Low preset averages 141 FPS, a remarkable figure for 4K. The Medium preset averages 95 FPS, with a minimum of 81 FPS and a maximum of 109 FPS, indicating some frame time variance under load. The High preset averages 80 FPS. The Ultra preset is the most demanding, yielding an average of 61 FPS, which is at the edge of what is considered ideal for a smooth 60 FPS experience.

Settings Recommendations

The measured data allows for clear, data-driven recommendations based on the user's target resolution and refresh rate.

For 1920x1080 users with a 144Hz or 165Hz monitor, the High preset is the optimal choice. It delivers 175 FPS, which is well above the refresh rate of most high-refresh 1080p monitors. The jump to Ultra only provides a marginal visual improvement at the cost of 25 FPS, making High the sweet spot for maximizing fluidity. For those with a 240Hz panel, the Low preset is the only option to approach that 216 FPS average, but the visual sacrifice is significant.

For 2560x1440 users, the High preset is the best experience. The 136 FPS average is high enough for a 144Hz monitor, and it offers a substantial visual upgrade over Low or Medium. The Medium preset, with its 161 FPS average and tight frame times (min 136), is a fantastic choice for those who prioritize a rock-solid framerate above all else. The Ultra preset is playable, but at 103 FPS, it sacrifices the high-refresh-rate advantage that makes 1440p so appealing.

For 3840x2160 users, the choices are more constrained. The Medium preset is the recommended starting point. It provides an average of 95 FPS, which is a good balance of visual fidelity and performance, though the 81 FPS minimum shows it can dip. The High preset at 80 FPS is also viable for 60Hz displays, offering better image quality. The Ultra preset, at 61 FPS, is only for users who prioritize maximum graphical fidelity over a completely smooth experience, as it sits right at the 60 FPS threshold. The Low preset at 141 FPS is viable for competitive play, but it negates the point of a high-end GPU by severely reducing visual quality.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture. Its base clock is 3.70 GHz and it boosts up to 4.70 GHz. These specifications are crucial for Rust, which relies heavily on a few fast cores. The processor's Cinebench R23 multi-core score of 21765 and single-core score of 3072 indicate a strong all-around performer, but the single-core strength is particularly relevant here. The high boost clock of 4.70 GHz ensures that the main game thread can be processed quickly, which is a primary reason why frame rates remain high even at 1080p.

The CPU's 32 MB of shared L3 cache is also a beneficial asset. Rust's world interactions and entity updates often require quick access to data, and a larger cache can reduce the latency of these operations. The cache structure, with 1 MB of L2 per core and 64 KB of L1 per core, is a standard design that provides a balanced hierarchy. The Passmark multi-thread score of 25645 and integer math score of 74745 further illustrate the processor's capability in handling the complex simulation and logic tasks that Rust presents.

However, the data suggests that the 7400F is the bottleneck at lower resolutions. The fact that the frame rate at 1080p Low (216 FPS) is not proportionally higher than 1080p High (175 FPS) implies that the CPU is maxing out its ability to feed draw calls and process game logic. The combo's rank of 76th out of 2953, while excellent, is lower than what one might expect from a GPU in the 92nd percentile, which is a direct consequence of the CPU's 83rd percentile standing. The CPU's nearest rivals, like the Intel Core i5-14600T, are within 0.1% in average score, confirming that the 7400F is performing to its expected level, but that level is simply below what the RTX 5090 D can offer.

GPU Role

The NVIDIA GeForce RTX 5090 D is a monolithic powerhouse. Its specifications are staggering: 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. This immense memory capacity and bandwidth are more than sufficient for Rust, even at 4K with high-resolution textures. The GPU's 21760 shading units, 680 TMUs, and 176 ROPs, combined with a boost clock of 2407 MHz, deliver a raw compute capability of 104.8 TFLOPS. These numbers translate directly to the high pixel and texture rates of 423.6 GPixel/s and 1,636.8 GTexel/s, respectively.

The GPU's performance is the driving force behind the combo's high rank. Its Passmark G3D score of 44065 and average benchmark score of 77712 place it in the 92nd percentile. This raw power is what allows the system to achieve 80 FPS at 4K High, a feat that would be impossible with a lesser graphics card. The 32 GB of VRAM is also a future-proofing asset, ensuring that texture data never has to be swapped out, even with the largest mods or highest quality settings.

Despite its power, the RTX 5090 D's role is clearly defined by the resolution. At 1080p, it is underutilized, as the CPU cannot keep up. The GPU's full potential is only realized at 2560x1440 and especially 3840x2160, where the scaling between settings presets is much more pronounced. At 4K, the GPU's massive shading and memory bandwidth resources are finally taxed, as evidenced by the 56.7% difference in performance between Low and Ultra settings. The GPU's nearest rivals, such as the AMD Radeon RX 6850M XT, are only 1.6% higher in average score, indicating that this desktop card is a top-tier performer, but its capabilities are gated by the CPU at lower resolutions.
