Rust

The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 4080 delivers a robust performance profile in Rust, with the data showing a clear progression from high refresh rate dominance at 1080p to playable, though less extreme, frame rates at 4K. This combination ranks in the 201st position out of 3,723 tested combos, placing it comfortably within the top 5.4% of all systems evaluated for this title. The benchmark results reveal a system that is exceptionally well-balanced for Rust's unique demands, where both the CPU's large cache and the GPU's substantial memory bandwidth play critical roles in maintaining high frame rates across various settings and resolutions.

Resolution Scaling

The measured FPS data reveals a pronounced sensitivity to resolution scaling, which is a key indicator of how the workload shifts between components. At 1080p with Low settings, the combo achieves an average of 259 FPS, a figure that drops to 198 FPS at 1440p and further to 117 FPS at 4K. This progression shows a 54% reduction in frame rate from 1080p to 4K at Low settings, suggesting that while the CPU is capable of feeding the GPU at lower resolutions, the GPU becomes increasingly burdened as pixel count rises.

The scaling pattern shifts notably when examining higher settings. At Ultra settings, the average FPS goes from 124 at 1080p, to 85 at 1440p, and finally to 50 at 4K. The percentage drop from 1080p to 4K at Ultra is nearly identical to Low (approximately 60%), but the absolute numbers are much lower, indicating that the GPU is the limiting factor at these higher fidelity levels. The data implies that at 1080p, the system has enough headroom that even Ultra settings produce over 120 FPS, which is excellent for competitive play, whereas 4K Ultra dips to a point where the experience becomes less fluid.

Interestingly, the scaling from 1440p to 4K is more severe than from 1080p to 1440p across all settings. For High settings, the drop from 1440p to 4K is 46 FPS (112 to 66), while the drop from 1080p to 1440p is 51 FPS (163 to 112). This non-linear scaling suggests that the RTX 4080's 16 GB of VRAM and 716.8 GB/s of memory bandwidth are being pushed hard at 4K, where the increased pixel workload and texture data requirements start to tax the GPU's resources significantly. The results indicate that this combo is best suited for 1080p and 1440p gaming, with 4K being viable only when settings are lowered to Medium or below.

How This Combo Ranks

The comboRankInGame field places this specific configuration at rank 201 out of 3,723 total combos tested for Rust. This top 5.4% ranking is a strong indicator of the system's overall capability, but it is important to contextualize this against the individual component strengths. The CPU, AMD Ryzen 7 9800X3D, holds a percentile ranking of 87 against all CPUs, while the GPU, NVIDIA GeForce RTX 4080, sits at a percentile of 86 against all GPUs. The combination of two high-percentile components results in a system that outperforms the vast majority of other tested configurations.

The nearestRivals data for the CPU shows it is extremely competitive with other high-end processors. The Ryzen 7 9800X3D has an average benchmark score of 39,768, which is only 0.4% higher than the AMD Ryzen 7 PRO 8840HS (39,603) and 0.8% higher than the AMD Ryzen 7 7700 (40,081). However, it trails the AMD Ryzen AI 9 365 (40,048) by 0.7% and the AMD Ryzen AI 7 450 (39,485) by 0.7% in raw average score. This suggests that while the CPU is not the absolute top performer in synthetic benchmarks, its 96 MB of shared L3 cache provides a distinct advantage in a game like Rust, which is known for its heavy reliance on cache-sensitive workloads.

For the GPU, the RTX 4080's average benchmark score of 54,247 places it nearly identical to the RTX 4080 SUPER (54,209, deltaPct 0.1%). It is slightly behind the AMD Radeon Pro W5700X (54,828, -1.1%) and the AMD Radeon RX 6750 GRE 12 GB (55,698, -2.6%). This data shows that the GPU is a very capable performer, but its ranking within the combo is likely more influenced by the CPU's ability to maintain high frame rates in Rust's CPU-intensive scenarios. The overall combo rank of 201 suggests there are 200 other configurations that achieve higher average FPS, likely including systems with newer or more powerful GPUs that can push higher frame rates at lower resolutions.

CPU Role

The AMD Ryzen 7 9800X3D is built on the Zen 5 architecture using the Granite Ridge codename and a 4 nm process node from TSMC. It features 8 cores and 16 threads, with a base clock of 4.70 GHz and a boost clock of 5.20 GHz. The CPU's cache hierarchy is particularly notable for gaming: it includes 80 KB of L1 cache per core, 1 MB of L2 cache per core, and a massive 96 MB of shared L3 cache. This large L3 cache is a hallmark of the X3D series and is designed to reduce memory latency, which is crucial for games that frequently access the same data.

In Rust, where the game world is simulated with many entities and complex interactions, the CPU's cache capacity can significantly impact frame rates. The benchmark data supports this theory. At 1080p Low settings, the system achieves 259 FPS, which is remarkably high and suggests the CPU is not the primary bottleneck at this resolution. The 3DMark scores for the CPU are telling: it scores 10,081 in the 16-thread test and 12,120 in the single-thread test, indicating strong multi-threaded and single-threaded performance. Its Cinebench R23 scores of 23,230 (multicore) and 2,080 (singlecore) further reinforce this.

When the resolution increases to 4K, the CPU's role diminishes relative to the GPU. The FPS at 4K Low is 117, which is less than half of the 1080p Low score, showing that the GPU is now the limiting factor. However, the fact that the CPU can maintain 117 FPS at 4K Low indicates it has ample headroom to feed the GPU even at higher resolutions. The CPU's TDP is listed as 120W, and it supports DDR5 memory with a dual-channel bus and a memory bandwidth of 89.6 GB/s, which is more than sufficient for Rust's memory demands. The data suggests that this CPU is a top-tier choice for Rust, providing the necessary single-threaded performance and cache size to avoid bottlenecks at most settings.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's performance across three resolutions and four settings presets. At 1920x1080, the system delivers an average of 259 FPS on Low, 193 FPS on Medium, 163 FPS on High, and 124 FPS on Ultra. The Medium preset includes detailed data with a minimum of 164 FPS and a maximum of 222 FPS, showing reasonable frame time consistency. The 1080p results are exceptional, with even Ultra settings producing frame rates well above the 60 FPS threshold, making this resolution ideal for high-refresh-rate monitors.

Moving to 2560x1440, the average FPS drops to 198 on Low, 133 on Medium, 112 on High, and 85 on Ultra. The Medium preset at this resolution shows a minimum of 113 FPS and a maximum of 153 FPS, indicating that the system can maintain a smooth experience in the 100-150 FPS range. The High preset at 1440p produces 112 FPS, which is still very playable, while Ultra at 85 FPS offers a good balance between visual fidelity and performance for most users.

At 3840x2160, the system's performance takes a more significant hit. The average FPS is 117 on Low, 79 on Medium, 66 on High, and 50 on Ultra. The Medium preset at 4K shows a minimum of 67 FPS and a maximum of 90 FPS, making it the most consistent option for 4K gaming. The High preset at 66 FPS is still playable but may struggle to maintain a locked 60 FPS in demanding scenes. The Ultra preset at 50 FPS is the only setting that falls below the 60 FPS threshold, suggesting that this combo is not ideal for 4K Ultra settings in Rust. The data shows a clear trend: the system excels at 1080p and 1440p, while 4K requires careful settings management to achieve a smooth experience.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with the AD103 chip manufactured on a 5 nm process. It features 16 GB of GDDR6X memory on a 256-bit bus, providing a memory bandwidth of 716.8 GB/s. The GPU has a base clock of 2,205 MHz and a boost clock of 2,505 MHz, with a TDP of 320W. The 48.74 TFLOPS of FP32 compute power and 76 RT cores make it a formidable graphics card for both rasterization and ray tracing workloads.

In Rust, the GPU's role becomes increasingly important as resolution and settings are raised. At 1080p Low, the GPU is not stressed much, as evidenced by the 259 FPS average, which is likely CPU-limited. However, as settings are increased to High and Ultra, the GPU's workload grows, and the FPS drops to 163 and 124 respectively. This indicates that the RTX 4080 has enough power to handle Rust's visual effects at 1080p without issue, but the frame rate is still heavily influenced by the CPU.

At 1440p, the GPU starts to become more of a factor. The drop from Low to Ultra is from 198 FPS to 85 FPS, showing that the GPU's rendering workload is scaling with settings. The 16 GB of VRAM is likely sufficient for Rust's textures, even at 4K, as the game does not typically require more than 8-10 GB of VRAM at high settings. The memory bandwidth of 716.8 GB/s is also adequate, though the 4K results suggest it may be a limiting factor at Ultra settings.

The 4K Ultra result of 50 FPS is the most telling indicator of the GPU's limits in this game. The pixel count at 4K is four times that of 1080p, and the GPU's fill rate and shading power are taxed heavily. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are high but not enough to maintain 60+ FPS at 4K Ultra in Rust. The GPU's 3DMark Steel Nomad score of 6,567 and Passmark G3D score of 34,457 confirm it is a high-end card, but Rust's specific engine optimizations and heavy draw calls at 4K Ultra push it to its limits. The data suggests that for 4K gaming, dropping to High or Medium settings is necessary to maintain a fluid experience.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user's resolution and performance priorities. For 1920x1080, the Ultra preset provides an average of 124 FPS, which is well above the 60 FPS threshold and suitable for most high-refresh-rate (120Hz) monitors. The High preset at 163 FPS is even better for competitive play, offering a significant boost in frame rate with only a minor visual sacrifice. For users with 144Hz or higher refresh rate monitors, the High preset is recommended, while Ultra is fine for 60Hz displays.

At 2560x1440, the High preset delivers 112 FPS, which is the best balance between visual quality and performance. The Ultra preset at 85 FPS is also playable but may not be ideal for fast-paced gameplay. The Medium preset at 133 FPS offers a higher frame rate for those who prioritize smoothness over visual fidelity. For a 144Hz monitor at 1440p, the Medium preset is the recommended choice, as it stays above 130 FPS and provides a competitive advantage.

For 3840x2160, the Medium preset is the clear winner, with an average of 79 FPS and a minimum of 67 FPS. This is the only 4K setting that consistently stays above 60 FPS, making it the recommended choice for a smooth 4K experience. The High preset at 66 FPS is borderline and may experience dips below 60 FPS in heavy scenes. The Low preset at 117 FPS is viable for those who prioritize frame rate over everything else, but the visual quality is severely compromised. The Ultra preset at 50 FPS should be avoided, as it falls short of the 60 FPS target and will result in a less fluid experience. Overall, the data indicates that this combo is best utilized at 1080p or 1440p with High or Ultra settings, with 4K reserved for Medium settings or lower.
