Rust

The AMD Ryzen 7 5700G paired with the AMD Radeon RX 6600 presents a specific performance profile in Rust, a survival title known for its demanding engine. The measured frame rates across resolutions and presets reveal a system that is firmly balanced between its eight-core processor and mid-range graphics card. This analysis breaks down the data to show where the bottlenecks lie and how to best configure the game for a playable experience.

Resolution Scaling

The data shows a clear and expected progression of frame rates as resolution increases, but the magnitude of the drop reveals the GPU’s role as the primary scaling limiter. At 1080p with Low settings, the combo achieves 125.4 FPS. Moving to 1440p Low drops this to 85.8 FPS, a significant 31.5% reduction. At 4K Low, the frame rate falls to 49.9 FPS, which is just 39.8% of the 1080p figure. This indicates that while the CPU is capable of feeding the GPU at lower resolutions, the RX 6600’s rendering workload becomes the dominant constraint as pixel count increases.

The pattern persists across all presets. At High settings, the drop from 1080p (68.6 FPS) to 1440p (47.8 FPS) is a 30.3% decrease, and the slide to 4K (28.1 FPS) represents a 59% loss from the 1080p baseline. The Ultra preset tells a similar story: 51.5 FPS at 1080p falls to 37.3 FPS at 1440p and finally to just 24.4 FPS at 4K. The consistency of these percentage drops across different quality levels suggests the scaling is driven primarily by the GPU’s fill rate and memory bandwidth rather than a sudden CPU limitation. The RX 6600’s 8 GB of GDDR6 memory over a 128-bit bus, providing 224.0 GB/s of bandwidth, appears sufficient for 1080p but becomes stressed as resolution increases.

Notably, the gap between Low and Ultra settings narrows as resolution climbs. At 1080p, the difference between Low (125.4 FPS) and Ultra (51.5 FPS) is 73.9 FPS. At 4K, the gap between Low (49.9 FPS) and Ultra (24.4 FPS) shrinks to 25.5 FPS. This convergence indicates that at 4K, the GPU is so heavily loaded that even reducing graphical fidelity cannot recover high frame rates, confirming that the RX 6600 is the definitive limiting component at that resolution.

How This Combo Ranks

Within the database of tested combinations for Rust, this pairing of the Ryzen 7 5700G and RX 6600 holds a rank of 1408 out of 1717 combos. This places it in the lower percentile of all tested systems, suggesting that while it can run the game, it does not deliver top-tier performance compared to more powerful pairings. The rank reflects a system that is likely geared toward 1080p gaming rather than high-refresh-rate or high-resolution play.

The CPU itself is not the weak link in this ranking. The Ryzen 7 5700G sits in the 83rd percentile against all CPUs, with an average benchmark score of 25626. Its nearest rivals, such as the AMD Ryzen 7 6800U (25706 score, -0.3% delta) and the Intel Core 5 210H (25490 score, 0.5% delta), show that the processor is competitive with other mid-range options. However, the GPU’s 69th percentile ranking against all GPUs, with an average score of 25235, aligns more closely with the combo’s overall low rank. The RX 6600’s nearest rival, the AMD Radeon 890M (25246 score, 0% delta), shows it is an average performer, and this mediocrity drags the combined system down in the rankings.

The data suggests that the combo’s rank is not due to a fundamental mismatch, but rather the inherent limits of both components. In a game like Rust, which is sensitive to both CPU and GPU, the system lands in the lower half of the field. Users expecting high-end competitive frame rates will be disappointed, but the rank does not imply the system is unusable, merely that it is positioned below the majority of tested configurations.

GPU Role

The AMD Radeon RX 6600, based on the RDNA 2.0 architecture with the Navi 23 chip, is the primary driver of the frame rate differences seen across settings. Its 8 GB of GDDR6 memory is a fixed resource that cannot be upgraded, and the measured data shows how this capacity interacts with the game’s demands. At 1080p, the memory is adequate, allowing the GPU to push 125.4 FPS at Low settings. However, at 4K, the higher memory pressure and increased pixel workload cause a dramatic performance collapse, with Ultra settings yielding only 24.4 FPS.

The clock speeds provide context for these results. The GPU has a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. The boost clock represents the maximum potential, but sustained loads in Rust will likely keep the card closer to the game clock. The 14 Gbps effective memory speed, paired with the 128-bit bus, gives a bandwidth of 224.0 GB/s. This bandwidth is a likely contributor to the performance drop at 4K, as the GPU must fetch more texture and geometry data per frame, and the limited bus width becomes a bottleneck.

The GPU’s 1792 shading units and 64 ROPs are modest by modern standards, and the FP32 performance of 8.928 TFLOPS places it firmly in the entry-level to mid-range segment. The benchmark scores reflect this: a Passmark G3D score of 15096 and a 3DMark Steel Nomad DX12 score of 1492. These numbers are not exceptional, and the 69th percentile ranking against all GPUs confirms that the RX 6600 is a capable but not powerful card. In Rust, this translates to playable 1080p performance but a struggle to maintain smooth frame rates at higher resolutions or with Ultra settings.

Settings Recommendations

The measured frame rate data offers a clear guide for optimal settings, with the goal of balancing visual quality against a playable frame rate. At 1080p, the High preset provides a solid 68.6 FPS, which is well above the 60 FPS threshold for smooth gameplay. This is the recommended baseline for most users, as it offers a significant visual upgrade over Low (125.4 FPS) without the performance penalty of Ultra (51.5 FPS). The Medium preset at 85.1 FPS is also viable for those prioritizing higher frame rates over visual fidelity.

At 1440p, the situation becomes more constrained. The High preset drops to 47.8 FPS, which is below the ideal 60 FPS mark. The Medium preset at 57.7 FPS is closer to playable, but the Low preset at 85.8 FPS is the only option that clearly exceeds 60 FPS. For a 1440p display, the data suggests that Low or Medium settings are necessary to maintain smooth gameplay, with High and Ultra (37.3 FPS) being less suitable for fast-paced action.

At 4K, the data indicates that the RX 6600 is overmatched. Even the Low preset only manages 49.9 FPS, and the High preset falls to 28.1 FPS. The Ultra preset at 24.4 FPS is effectively unplayable. The recommendation for 4K is to avoid this resolution entirely, or to accept Low settings with the understanding that frame rates will be sub-optimal. The data clearly shows that 1080p is the sweet spot for this combo, with High settings offering the best balance of performance and visual quality.

CPU Role

The AMD Ryzen 7 5700G, with its 8 cores and 16 threads based on the Zen 3 architecture, provides a solid foundation for Rust. Its base clock of 3.80 GHz and boost clock of 4.60 GHz are healthy for a desktop processor. The 16 MB of L3 cache is a key asset, as Rust’s world simulation and entity updates often benefit from larger caches. The CPU’s benchmark results, such as a Geekbench multicore score of 8970 and a Passmark single-thread score of 3283, indicate strong multi-threaded and single-threaded capabilities.

In the measured data, the CPU’s influence is most visible in the 1080p results. At 1080p Low, the system achieves 125.4 FPS, which is high enough to suggest that the CPU is not creating a hard ceiling. However, at 4K, the frame rates drop dramatically regardless of settings, which points to the GPU as the limiting factor. The CPU is likely still feeding the GPU effectively, but the GPU cannot render the frames fast enough at higher resolutions.

The 5700G’s percentile ranking of 83 against all CPUs, and its average benchmark score of 25626, place it above the RX 6600’s 69th percentile GPU ranking. This suggests that the CPU has more headroom than the GPU. In a game like Rust, which can be CPU-intensive in complex scenes with many players and structures, the 8-core/16-thread configuration is a good match. The data shows that the CPU is not the bottleneck in this pairing; the RX 6600 is the component that limits performance, particularly at resolutions above 1080p.
