FAQ

Q: How does this CPU compare to its nearest rivals in average benchmark score?

A: The AMD Ryzen 7 5800XT scores 29,774, placing it within a tight margin of its closest competitors. It is 0.1% ahead of the AMD Ryzen 7 PRO 5755GE and 0.3% ahead of the AMD Ryzen AI 7 PRO 360, while trailing the AMD Ryzen 7 6800HS and AMD Ryzen 7 7840H by 0.3% each.

Q: What is the highest average FPS this combination achieves in Rust?

A: The peak performance is observed at 1920x1080 with Low settings, where the system produces 209.3 FPS on average. This is the only measured configuration that exceeds the 200 FPS threshold.

Q: What is the lowest average FPS recorded for this setup?

A: The most demanding configuration, 3840x2160 at Ultra settings, yields the lowest result at 56.1 FPS. This remains comfortably playable, but it represents a significant drop from other settings at that resolution.

Q: Does the RTX 4090’s massive 24 GB of VRAM show a performance benefit in Rust?

A: The 24 GB of GDDR6X memory provides ample capacity for the game, but the data suggests that raw compute power and rasterization speed are the primary drivers of FPS differences. The large frame buffer does not prevent the substantial FPS drops seen when moving from Low to Ultra settings, which are more indicative of shader and geometry load.

Q: How does the GPU’s benchmark percentile compare to the CPU’s?

A: The RTX 4090 sits in the 91st percentile of all GPUs, while the Ryzen 7 5800XT is in the 86th percentile of all CPUs. This indicates the GPU is the stronger component relative to its peers, which is reflected in the game’s performance scaling.

Q: What is the performance delta between the RTX 4090 and its closest rival in average benchmark score?

A: The RTX 4090’s average benchmark score is 66,473. It trails the NVIDIA Tesla T4 by 0.4% and the AMD Radeon Pro Vega 56 by 0.9%, but it is 0.5% ahead of the NVIDIA Tesla P40 and 1.3% ahead of the NVIDIA Quadro P6000.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant force in this pairing, equipped with 16,384 shading units and 176 ROPs. Its boost clock of 2520 MHz and memory bandwidth of 1.01 TB/s across a 384-bit bus provide the raw throughput needed for high-resolution gaming. The GPU’s FP32 performance of 82.58 TFLOPS is critical for the complex lighting and physics calculations Rust performs. The 128 RT cores and 512 tensor cores are present, but Rust’s traditional rasterization pipeline means the shader and texture units are the primary workhorses.

The data shows that the GPU is rarely the bottleneck until extremely high settings are applied. At 1080p Low, the system reaches 209.3 FPS, and even at 4K Low, it maintains 129.8 FPS. This performance headroom suggests the CPU is capable of feeding the GPU adequately at lower presets. However, the 24 GB VRAM capacity is not a limiting factor in any of these scenarios; the bottlenecks appear when the GPU’s compute units are saturated by the Ultra preset’s increased draw calls and post-processing effects. The GPU’s 91st percentile ranking among all GPUs confirms its elite status, and the data indicates it can handle the game’s most demanding settings, though with a significant FPS cost.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases, but the magnitude of the drop is highly dependent on the graphics preset. At Low settings, the system loses 79.5 FPS when moving from 1920x1080 to 3840x2160, a 38% reduction. This indicates that even at low graphical complexity, the increased pixel count at 4K begins to tax the GPU significantly.

At High settings, the drop from 1080p to 4K is 92.8 FPS (166.1 to 73.3), a 56% reduction. This suggests that the GPU is becoming the primary limiting factor as the resolution and preset complexity increase. The Ultra preset shows the most dramatic scaling, with a 84.2 FPS drop from 140.3 at 1080p to 56.1 at 4K. This 60% reduction highlights how the combination of high resolution and intensive settings can overwhelm the GPU’s capabilities, even one as powerful as the RTX 4090.

The data reveals that at 1080p and 1440p, the CPU can keep the GPU well-fed, as the FPS differences between Low and Medium settings are relatively modest. However, at 4K, the GPU is clearly the limiting component, as the performance gap between Low and Ultra becomes stark, with a 73.7 FPS difference. This analysis shows that the Ryzen 7 5800XT provides sufficient headroom for 1080p and 1440p gaming, but the RTX 4090’s raw power is what carries the system at higher resolutions.

Settings Recommendations

For players prioritizing high refresh rates at 1920x1080, the Low preset offers the best experience, delivering 209.3 FPS. This is the only configuration that breaks the 200 FPS barrier, making it ideal for competitive play. The Medium preset provides a solid middle ground at 175.8 FPS, a 16% reduction from Low but with improved visual fidelity. The High preset at 166.1 FPS is a viable alternative, though the Ultra preset at 140.3 FPS offers diminishing returns for the performance cost.

At 2560x1440, the Low preset again leads with 183.6 FPS, which is excellent for high-refresh monitors. Medium provides 144.7 FPS, a 21% drop, while High offers 123 FPS. The Ultra preset at 94.6 FPS is still playable but represents a significant 48% reduction from Low, making it less attractive for competitive play. The data suggests that Medium or High at 1440p offers the best balance of visual quality and performance.

For 3840x2160 gaming, the Low preset is the only option that approaches high refresh rates, delivering 129.8 FPS. Medium drops to 87.4 FPS, while High falls to 73.3 FPS. The Ultra preset at 56.1 FPS is the only configuration that dips below 60 FPS, making it the least recommended for a smooth experience. Given the data, players should use Low at 4K for fast-paced gameplay, or Medium if they prioritize visual quality over frame rate.

Measured FPS Breakdown

At 1920x1080, the performance spread is significant. The Low preset hits 209.3 FPS, providing the highest headroom. Medium follows at 175.8 FPS, which is 33.5 FPS lower. High reduces performance further to 166.1 FPS, a 43.2 FPS drop from Low. The Ultra preset, while still high at 140.3 FPS, represents the largest penalty, a 68.9 FPS reduction from Low. This shows a clear linear progression of performance loss as settings increase.

At 2560x1440, the same pattern holds but with lower absolute numbers. Low delivers 183.6 FPS, which is still excellent. Medium drops to 144.7 FPS, a 38.9 FPS difference. High reaches 123 FPS, a 60.6 FPS drop from Low. The Ultra preset at 94.6 FPS is the most demanding, showing a 89.0 FPS reduction from Low. The resolution increase from 1080p to 1440p costs roughly 25 FPS across all presets, indicating a consistent GPU load increase.

At 3840x2160, the performance is heavily dependent on settings. Low provides 129.8 FPS, which is a 79.5 FPS drop from the 1080p Low result, demonstrating the 4K pixel count’s impact. Medium falls to 87.4 FPS, a 42.4 FPS reduction from Low at the same resolution. High drops to 73.3 FPS, a 56.5 FPS decrease from Low. The Ultra preset at 56.1 FPS is the lowest measured result, showing a 73.7 FPS difference from Low. The gap between Low and Ultra widens from 68.9 FPS at 1080p to 73.7 FPS at 4K, confirming that the GPU becomes the bottleneck at higher resolutions and settings.
