Rust

Rust places heavy demands on both processor and graphics hardware, and the measured results for the AMD Ryzen 7 5700 paired with the AMD Radeon RX 7900 XTX show a configuration that is consistently capable but whose performance ceiling changes markedly with resolution and preset. The data indicates a system that excels at high refresh 1080p and 1440p gaming, while 4K Ultra remains a challenge, requiring preset adjustments to maintain smooth frame rates.

Settings Recommendations

For this specific combination of the Ryzen 7 5700 and Radeon RX 7900 XTX, the benchmark data suggests that the High preset offers the most balanced experience across all tested resolutions. At 1920x1080, High delivers an average of 149 FPS, which is 36 FPS lower than Low but still substantially above the refresh rate of most high-end monitors. Moving to 2560x1440, High produces an average of 102 FPS, a figure that remains fluid for competitive play. At 3840x2160, High is the only preset that maintains an average above 60 FPS, hitting exactly 60 FPS, which is the minimum target for a playable 4K experience.

If the priority is absolute smoothness on a 144Hz or higher refresh display, the Low preset is the clear choice. At 1080p, Low reaches 193 FPS, and at 1440p it achieves 170 FPS, both of which are well above 144. However, the jump from High to Low at 1440p represents a 68 FPS gain, which suggests that the GPU is not the primary limiter at these settings; rather, the CPU's single-threaded performance becomes more influential.

The Ultra preset is not recommended for this combo at any resolution. It produces an average of 113 FPS at 1080p, 78 FPS at 1440p, and only 46 FPS at 4K. The 4K Ultra result is below the 60 FPS threshold, making it an undesirable choice. The Medium preset is a viable fallback for 4K users who want better visuals than Low, delivering 72 FPS, but it does not offer the same value as High, which is only 12 FPS slower at that resolution.

GPU Role

The Radeon RX 7900 XTX is equipped with 24 GB of GDDR6 memory on a 384-bit bus, providing a bandwidth of 960.0 GB/s. This large memory pool and high bandwidth are directly relevant to Rust's performance, as the game's asset streaming and draw distances can consume significant video memory. The data shows that at 4K, the GPU's capabilities are the defining factor: the frame rate drops from 107 FPS at Low to 60 FPS at High, a 47 FPS reduction, and further to 46 FPS at Ultra. This steep scaling with preset quality at 4K indicates that the GPU's shading units and rasterization throughput are being fully exercised.

The GPU's clock speeds are listed with a base of 1929 MHz and a boost of 2498 MHz, with a game clock of 2365 MHz. These figures, combined with the 6144 shading units and 192 ROPs, explain why the card can maintain high frame rates at lower resolutions. At 1080p Low, the GPU is not the bottleneck, as evidenced by the 193 FPS result, which is only 27 FPS higher than the High preset. This suggests that the CPU is beginning to limit performance at these lower settings.

The 24 GB VRAM capacity is particularly relevant for Rust, which is known for its large maps and persistent world structures. The benchmark results show that even at 4K Ultra, the GPU does not run out of memory, as the frame rate is still consistent, albeit low. The data does not include any minimum FPS values for the Low and High presets at 4K, but the Medium preset shows a minimum of 61 FPS, suggesting that frame pacing remains stable when the GPU is not overwhelmed.

CPU Role

The Ryzen 7 5700 is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. Its multi-threaded performance is solid, as shown by a Cinebench R23 multi-core score of 20655, but Rust is often more sensitive to single-threaded performance. The single-core Cinebench R23 score of 2916 and a PassMark single-thread score of 3296 indicate that this CPU has adequate per-core strength for the game's simulation and physics threads.

Examining the measured FPS data, the CPU's role becomes more apparent at 1080p. The difference between Low and High at 1080p is only 44 FPS (193 vs 149), while the difference between Medium and High is 17 FPS (166 vs 149). This compression of frame rates at higher settings suggests that the CPU is not the limiting factor when the GPU has less work to do. However, at 1440p, the gap between Low and High widens to 68 FPS (170 vs 102), indicating that the GPU is taking on more load, and the CPU is keeping pace.

The processor's 16 MB of L3 cache and 51.2 GB/s memory bandwidth are adequate for feeding the GPU, but the data shows that at 4K, the CPU is effectively not a bottleneck. The 4K frame rates scale almost entirely with the GPU's workload, going from 107 FPS at Low to 46 FPS at Ultra. This is a clear sign that the Ryzen 7 5700 has enough headroom to keep the RX 7900 XTX supplied with data at high resolutions, where the GPU's 61.39 TFLOPS of FP32 performance becomes the decisive factor.

How This Combo Ranks

Within the database of tested combinations, this specific pairing of the Ryzen 7 5700 and Radeon RX 7900 XTX holds the rank of 573 out of 3723 total combos. This places it in the top 15.4 percent of all tested configurations, which is a strong showing given the CPU's mid-range positioning. The CPU's percentile vs all CPUs is 78, meaning it outperforms 78 percent of tested processors, while the GPU's percentile vs all GPUs is 64, which is lower but still above average.

The CPU's nearest rivals in terms of average benchmark score include the Intel Xeon D-2752TER, which is 0.1 percent slower, and the AMD Ryzen 5 7640U, which is 0.1 percent faster. These are close matches, indicating that the Ryzen 7 5700 sits in a well-populated performance tier. The GPU's nearest rivals show a similar pattern, with the NVIDIA GeForce GTX 1060 3 GB being 0.4 percent slower and the NVIDIA TITAN Xp being 1.2 percent faster. This is a peculiar grouping, as the RX 7900 XTX is a modern high-end card, but its average benchmark score of 19410 places it near older, less powerful GPUs, likely due to the specific benchmark suite used.

The comboRankInGame of 573 suggests that while the GPU is powerful, the CPU's performance is holding the combination back from the top tiers. In Rust, where frame rates at 1080p and 1440p are often CPU-bound, the Ryzen 7 5700's single-threaded performance is adequate but not exceptional, preventing the system from reaching the very highest echelons of performance seen with faster processors.

A: Yes, the data suggests the CPU limits performance at 1080p Low, where the frame rate is 193 FPS. The difference between Low and High at 1080p is only 44 FPS, which is smaller than the 68 FPS gap at 1440p, indicating that the CPU is unable to push much beyond 193 FPS.

Q: How much VRAM does the GPU have, and is it enough for Rust?

A: The Radeon RX 7900 XTX has 24 GB of GDDR6 memory. This is more than sufficient for Rust, as the game does not appear to be VRAM-limited at any preset or resolution in the measured data.

Q: What are the minimum FPS values for the Medium preset?

A: The Medium preset has reported minimum FPS values of 141 at 1080p, 103 at 1440p, and 61 at 4K. These values indicate that frame pacing is stable, with the 4K minimum being close to the average of 72 FPS.

Q: How does this combo rank compared to other tested systems?

A: This combination ranks 573 out of 3723 tested combos, placing it in the top 15.4 percent. The CPU ranks in the 78th percentile among all CPUs, while the GPU ranks in the 64th percentile among all GPUs.

Q: Does the GPU's performance scale linearly with resolution?

A: No, the scaling is not linear. From 1080p to 1440p on the High preset, the frame rate drops from 149 to 102 FPS, a 31.5 percent reduction. From 1440p to 4K on the same preset, it drops from 102 to 60 FPS, a 41.2 percent reduction, showing that the GPU's workload increases more steeply at higher resolutions.

Measured FPS Breakdown

The measured frame rates for this combination are consistent across resolutions and presets. At 1920x1080, the Low preset produces the highest average of 193 FPS, followed by Medium at 166 FPS, High at 149 FPS, and Ultra at 113 FPS. The Medium preset has a minimum of 141 FPS and a maximum of 191 FPS, showing a tight range that indicates consistent performance.

At 2560x1440, the ordering remains the same: Low delivers 170 FPS, Medium 121 FPS, High 102 FPS, and Ultra 78 FPS. The Medium preset at this resolution has a minimum of 103 FPS and a maximum of 139 FPS, which is a wider spread than at 1080p but still within a playable range.

At 3840x2160, the performance drops significantly. Low achieves 107 FPS, Medium 72 FPS, High 60 FPS, and Ultra 46 FPS. The Medium preset reports a minimum of 61 FPS and a maximum of 82 FPS, which is a 21 FPS spread, indicating that the GPU is working harder to maintain frame rates at this resolution.

The data shows that the step from High to Ultra at any resolution incurs a substantial penalty. At 1080p, the drop is 36 FPS; at 1440p, it is 24 FPS; and at 4K, it is 14 FPS. This suggests that the Ultra preset introduces features that are disproportionately expensive on this hardware, making it a poor choice for this combo.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the balance between CPU and GPU load. On the Low preset, the average FPS drops from 193 at 1080p to 170 at 1440p (a 11.9 percent decrease) and then to 107 at 4K (a 37.1 percent decrease from 1440p). This pattern indicates that at Low settings, the CPU is the primary limiter at 1080p and 1440p, as the GPU has plenty of headroom. The larger drop to 4K suggests that the GPU finally becomes the bottleneck.

On the High preset, the scaling is more consistent: 149 FPS at 1080p, 102 FPS at 1440p (a 31.5 percent drop), and 60 FPS at 4K (a 41.2 percent drop). This shows that as settings increase, the GPU's workload grows faster, and the CPU is less of a factor. The 4K High result of 60 FPS is exactly at the threshold for smooth gameplay, indicating that the GPU is fully utilized.

The Ultra preset shows the steepest scaling curve: 113 FPS at 1080p, 78 FPS at 1440p (a 31 percent drop), and 46 FPS at 4K (a 41 percent drop). The 4K Ultra result is below 60 FPS, which is the minimum for a playable experience. The data suggests that the GPU's 24 GB of VRAM is not the issue at 4K Ultra, as the frame rate is still proportional to the resolution increase, but rather the raw compute power of the GPU is insufficient to maintain high frame rates with all features enabled.

Overall, the resolution scaling analysis shows that this combo is well-suited for high-refresh 1080p and 1440p gaming, with the CPU providing enough single-threaded performance to drive high frame rates at lower settings. For 4K gaming, the GPU becomes the limiting factor, and users must choose between the High preset for 60 FPS or the Low preset for higher frame rates, with Ultra being a non-viable option.
