Rust

The AMD Ryzen 5 7400F and AMD Radeon RX 6700 XT combination delivers a playable but inconsistent experience in Rust, with performance heavily dependent on resolution and quality settings. The measured data shows a system that is clearly capable of high refresh rates at 1080p but struggles to maintain smooth frame rates at 4K. This analysis breaks down the benchmark results, focusing on how the CPU and GPU interact with the game’s demands.

Resolution Scaling

The measured FPS data reveals a predictable and steep performance decline as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 93 FPS at 1080p to 64 FPS at 1440p, a reduction of approximately 31%. Moving to 4K, the average falls further to 38 FPS, which is a 59% decrease from the 1080p baseline. This scaling pattern is typical and indicates that the GPU becomes the primary limiting factor at higher resolutions.

The Low preset shows a similar trajectory. The system achieves 165 FPS at 1080p, which is an excellent result for competitive play. At 1440p, this drops to 114 FPS, and at 4K, it falls to 67 FPS. The performance difference between the Low and High presets at the same resolution is substantial, highlighting that graphical settings have a massive impact on the workload. At 1080p Low, the system is likely CPU-bound, as the 165 FPS average suggests the GPU has enough headroom to render frames faster than the CPU can feed it. However, as resolution increases, the GPU’s workload grows, and the frame rate becomes more dependent on the RX 6700 XT’s pixel throughput.

The Medium preset provides the most complete data, including minimum and maximum FPS values. At 1080p Medium, the average is 111 FPS with a minimum of 94 FPS and a maximum of 127 FPS. At 1440p Medium, the average drops to 76 FPS, with a minimum of 65 FPS and a maximum of 88 FPS. At 4K Medium, the average is 45 FPS, with a minimum of 38 FPS and a maximum of 52 FPS. The gap between minimum and maximum FPS widens at higher resolutions, suggesting that the GPU is encountering more demanding scenes that cause frame time spikes. The jump from 1080p to 1440p at Medium results in a 31.5% performance drop, while the jump from 1440p to 4K results in a 40.8% drop, showing that 4K is disproportionately harder for this GPU.

The Ultra preset is the most demanding, yielding averages of 71 FPS at 1080p, 49 FPS at 1440p, and 29 FPS at 4K. The 4K Ultra result is effectively unplayable for smooth gameplay, as it falls below the 30 FPS threshold that is generally considered the bare minimum for playability. The data suggests that the RX 6700 XT is not a 4K-class GPU for this title, even at lower settings, as the 67 FPS at 4K Low is the only 4K result that approaches a smooth experience. The scaling from 1080p to 4K at Ultra represents a 59% performance loss, which is consistent with the High preset, indicating that the GPU’s memory bandwidth and compute capabilities are the limiting factors.

Settings Recommendations

Based on the measured rows, the optimal balance between visual quality and performance is achieved at the Medium preset. At 1080p, Medium delivers an average of 111 FPS, which is a significant improvement over the High preset’s 93 FPS while still offering better visuals than Low. The minimum FPS of 94 at 1080p Medium ensures that the experience remains fluid, with only minor dips during intense moments. This makes Medium the clear choice for 1080p displays, as it provides a high refresh rate experience without sacrificing too much visual fidelity.

For users with 1440p monitors, the Medium preset is again the recommended starting point. The average of 76 FPS is playable, but the minimum of 65 FPS suggests that some scenes will cause noticeable stutter. The High preset at 1440p yields an average of 64 FPS, which is borderline for smooth play. Given that the difference between High and Medium is visually minor in many titles, the extra 12 FPS from the Medium preset is more valuable for maintaining a consistent frame rate. The Low preset at 1440p provides a comfortable 114 FPS, which is ideal for competitive players who prioritize frame rate over graphics.

At 4K, the situation is more challenging. The Ultra preset’s 29 FPS average is unplayable, and the High preset’s 38 FPS is also below the desired threshold for smooth gameplay. The Medium preset achieves 45 FPS, which is playable but not ideal. The Low preset provides the best 4K experience at 67 FPS, but this requires significant visual compromises. For a 4K display, the data suggests that users should either adopt the Low preset for a playable experience or lower the resolution to 1440p to use the Medium or High presets. The performance difference between 4K Low (67 FPS) and 1440p High (64 FPS) is minimal, but the visual quality improvement from the higher settings at 1440p is substantial.

GPU Role

The AMD Radeon RX 6700 XT is the dominant component in this configuration for determining performance at higher resolutions. Its 12 GB of GDDR6 memory on a 192-bit bus provides a memory bandwidth of 384.0 GB/s, which is sufficient for 1080p and 1440p gaming but becomes a limiting factor at 4K. The benchmark data supports this, as the performance drop from 1440p to 4K is steeper than the drop from 1080p to 1440p across all presets. The GPU’s 2560 shading units and 64 ROPs are tasked with rendering the complex scenes of Rust, and the data shows that they are overwhelmed at 4K Ultra.

The GPU’s clocks are relatively high, with a base clock of 2321 MHz and a boost clock of 2581 MHz. This allows the card to perform well in lighter loads, as evidenced by the 165 FPS at 1080p Low. However, the game clock of 2424 MHz is more representative of sustained gaming loads. The GPU’s performance percentile of 72 indicates that it is a mid-to-high tier card relative to all GPUs in the database. Its nearest rivals include the NVIDIA GeForce RTX 3090, which has a similar average benchmark score of 27565, showing a deltaPct of -0.5. This means the RX 6700 XT is roughly on par with the RTX 3090 in synthetic benchmarks, but the measured FPS data in Rust shows that it is not sufficient for 4K Ultra.

The GPU’s 12 GB of VRAM is a key attribute. At 1080p and 1440p, the VRAM capacity is unlikely to be a bottleneck, as the game’s textures can be stored within the 12 GB pool. At 4K, however, the larger texture sets and higher resolution buffers may approach the VRAM limit, potentially causing texture streaming issues that could contribute to the lower frame rates. The GPU’s TDP of 230 W and the suggested PSU of 550 W indicate that this is a power-hungry component, but the benchmark data does not include power consumption figures. The GPU’s performance in Rust is clearly tied to its rasterization capabilities, as the game does not heavily utilize ray tracing, and the RX 6700 XT’s 40 RT cores are not a significant factor in these results.

How This Combo Ranks

The combination of the AMD Ryzen 5 7400F and AMD Radeon RX 6700 XT ranks 1484 out of 2953 tested combos for Rust. This places it in the 50th percentile of all tested configurations, meaning it performs better than half of the combos in the database. This is a solid mid-pack result, reflecting the balanced nature of the CPU and GPU pairing. The rank suggests that while this system is not top-tier, it is also not a low-end configuration.

The CPU’s percentile of 83 against all CPUs is notably higher than the GPU’s percentile of 72. This indicates that the Ryzen 5 7400F is a stronger component relative to its peers than the RX 6700 XT. In the context of this game, this means the CPU has more headroom than the GPU. The combo’s rank is likely held back by the GPU’s performance at higher resolutions, as the CPU is capable of supporting higher frame rates if the GPU were faster. The data supports this interpretation, as the FPS at 1080p Low (165 FPS) is likely limited by the CPU, while the FPS at 4K Ultra (29 FPS) is clearly limited by the GPU.

Compared to the CPU’s nearest rivals, the Ryzen 5 7400F is closely matched. It is 0.1% faster than the Intel Core i5-14600T, 0.2% faster than the Intel Core Ultra 7 155H, and 0.3% faster than the AMD Ryzen AI 7 PRO 360. It is 0.2% slower than the AMD Ryzen 7 PRO 6850H. These differences are negligible, indicating that the CPU’s performance is in line with other mid-range options. The GPU’s nearest rivals also show similar performance, with the RX 6700 XT being 0% different from the NVIDIA GeForce RTX 4070 Mobile and 0.5% slower than the NVIDIA GeForce RTX 3090. This confirms that the combo’s performance is typical for its component class.

CPU Role

The AMD Ryzen 5 7400F plays a crucial role in this system, particularly at lower resolutions where the GPU is not the bottleneck. With 6 cores and 12 threads, the CPU is well-suited for modern games, and its Zen 4 architecture provides strong single-threaded performance. The base clock of 3.70 GHz and boost clock of 4.70 GHz are competitive, and the 32 MB of shared L3 cache helps reduce memory latency. The CPU’s performance is highlighted by its Cinebench R23 scores of 21765 in multi-core and 3072 in single-core, which are strong results for a 6-core processor.

In Rust, the CPU’s role is most evident at 1080p Low, where the GPU can render frames quickly, but the frame rate is capped at 165 FPS. This suggests that the CPU is the limiting factor at this setting, as the GPU has the capability to output more frames. The CPU’s Passmark single-thread score of 3689 is high, and its multithread score of 25645 indicates that it can handle the game’s simulation and physics calculations without issue. The CPU’s percentile of 83 against all CPUs confirms that it is a strong performer.

The Ryzen 5 7400F uses the AMD Socket AM5 platform and supports DDR5 memory with a dual-channel bus, providing a memory bandwidth of 83.2 GB/s. This memory bandwidth is sufficient for the CPU’s needs, and the 5 nm process node from TSMC ensures efficient operation with a TDP of 65 W. The CPU’s nearest rivals, such as the Intel Core i5-14600T and the AMD Ryzen 7 PRO 6850H, show very similar average benchmark scores, with deltas of 0.1% and -0.2%, respectively. This indicates that the CPU’s performance is in line with other mid-range options, and it is not a weak link in this combo.

The CPU’s boost clock of 4.70 GHz is key for maintaining high frame rates in Rust, as the game’s performance is often sensitive to single-threaded performance. The data shows that at 1080p, the CPU can push the GPU to its limits, but at 4K, the CPU’s performance is less relevant, as the GPU becomes the primary constraint. The CPU’s 12 threads are sufficient for the game’s multi-threaded tasks, and the 32 MB of L3 cache helps keep frequently accessed data close to the cores. Overall, the Ryzen 5 7400F is a capable partner for the RX 6700 XT, providing enough performance to avoid bottlenecking the GPU at lower resolutions while the GPU’s limitations are exposed at higher resolutions.
