Rust

Rust is a demanding survival title, and this pairing of an AMD Ryzen 5 4600G with an AMD Radeon RX 580 produces a playable, though not luxurious, experience. The data shows that the combination ranks 1584th out of 1717 tested combos in this game, placing it in the lower third of all systems. This is a setup that demands careful settings management, as the 8 GB of GDDR5 memory on the GPU and the CPU's Zen 2 architecture have clear limits when the game's heavy draw distances and physics simulation are pushed.

Resolution Scaling

The most telling data point is the dramatic drop in performance as resolution increases. At 1080p with Low settings, the system achieves 73.3 FPS, which is the only measured configuration that comfortably clears the 60 FPS threshold. Moving to 1440p at the same Low preset drops the average to 53.6 FPS, a 27% reduction. At 4K with Low settings, the system manages only 32.3 FPS, which is a 56% decrease from the 1080p result.

This scaling pattern reveals that the Radeon RX 580 is the primary limiting factor at higher resolutions. The GPU's 256-bit memory bus and 256.0 GB/s bandwidth are strained by the pixel count of 4K, and the 14nm Polaris architecture's 6.175 TFLOPS of FP32 performance is insufficient for the workload. The CPU is less of a bottleneck here; the Ryzen 5 4600G's 6 cores and 12 threads provide enough headroom to feed the GPU at lower resolutions, but the GPU simply runs out of pixel-pushing capability.

The gap between Low and Ultra settings widens as resolution increases. At 1080p, Low to Ultra is a 41.3 FPS difference (73.3 down to 32.0). At 4K, that same settings jump only changes the result by 19.4 FPS (32.3 down to 12.9). This compression at 4K indicates that the GPU is completely saturated regardless of quality preset, making higher resolutions a poor choice for any competitive play.

FAQ

Q: Can this system run Rust at 60 FPS?

A: Only at 1080p with Low settings, where it achieves 73.3 FPS. All other measured configurations fall below 60 FPS, with 1080p Medium at 47.7 FPS and 1080p High at 43.3 FPS.

Q: Is 8 GB of VRAM enough for Rust?

A: The 8 GB GDDR5 memory is present, but the data suggests it is not the sole constraint. At 4K Ultra, the system drops to 12.9 FPS, indicating that raw GPU compute power is the bottleneck rather than memory capacity alone, as the Polaris chip's 32 ROPs and 144 TMUs cannot handle the load.

Q: What is the best resolution for this combo?

A: 1920x1080 is the only resolution that offers any playable frame rates. At 1440p, the best case is 53.6 FPS on Low, which is borderline, and 4K is not viable for anything above 32.3 FPS on Low.

Q: How much faster is Low vs. Ultra at 1080p?

A: Low settings deliver 73.3 FPS, while Ultra delivers 32.0 FPS. This is a 2.29x improvement in frame rate from the lowest to the highest quality preset.

Q: Does the CPU's integrated graphics matter here?

A: The Ryzen 5 4600G includes Radeon Vega 7 integrated graphics, but the discrete RX 580 is always used for rendering. The CPU's 4.20 GHz boost clock and 8 MB of shared L3 cache contribute to physics and entity processing, but the GPU is the limiting factor.

Q: How does this compare to other CPUs in the same class?

A: In synthetic benchmarks, the Ryzen 5 4600G scores 17489 on average. This is virtually tied with the AMD Ryzen 3 PRO 5355GE (17482, 0% delta) and the Intel Core i5-12450H (17475, 0.1% delta), but slightly behind the Intel Core i3-14100T (17636, -0.8% delta) and Core i3-13100F (17665, -1% delta).

Settings Recommendations

The measured data clearly shows that Low settings are the only viable path for a consistent experience. At 1080p Low, the system produces 73.3 FPS, which is the only result above 60 FPS. This should be the baseline for any player who values responsiveness in combat or building mechanics. Medium settings at 1080p drop to 47.7 FPS, which is playable but will feel sluggish in firefights, while High at 43.3 FPS and Ultra at 32.0 FPS are progressively worse.

For 1440p, Low settings at 53.6 FPS is the only acceptable option, but this comes with a significant visual downgrade. The step from Low to Medium at 1440p costs 19.2 FPS (from 53.6 to 34.4), which is a 36% penalty for marginal quality gains. At 4K, no settings preset is recommended, as even Low only achieves 32.3 FPS, which is below the threshold for smooth gameplay.

The practical advice is to run 1080p with Low settings and consider adjusting a few in-game options that are not directly measured, such as draw distance, to improve visibility without impacting the core frame rate. The data does not support using Medium or higher presets at any resolution if a stable frame rate is the priority.

How This Combo Ranks

The combination of the Ryzen 5 4600G and RX 580 ranks 1584th out of 1717 tested combos in Rust. This places it in the 8th percentile of all systems tested, meaning 92% of tested configurations deliver better performance. This low ranking is consistent with the measured FPS data, as the system struggles to maintain playable frame rates at higher settings.

Relative to other components, the CPU holds its own in synthetic tests, with a 75th percentile ranking among all CPUs. However, the GPU is only at the 53rd percentile among all GPUs, and its nearest rivals in the benchmark database are older cards like the NVIDIA GeForce GTX 570 (13564 avg score, 0% delta) and the GTX 950 (13549, 0.1% delta). This GPU performance ceiling is what drags the combo ranking down, as Rust's rendering demands far exceed what the Polaris 20 chip can deliver.

The 1717 tested combos represent a wide range of hardware, and this pairing sits near the bottom. For context, the CPU's synthetic average of 17489 is close to the Intel Core i3-13100F (17665, -1% delta), but the GPU's limitations prevent the system from translating that CPU capability into gaming performance.

GPU Role

The AMD Radeon RX 580 is the decisive component in this pairing, and its specifications explain the measured results. The GPU has 2304 shading units, 144 texture mapping units, and 32 raster operators, all running at a boost clock of 1340 MHz. This configuration delivers 42.88 GPixel/s pixel rate and 193.0 GTexel/s texture rate, which are modest figures by modern standards.

The 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth. This is sufficient for 1080p textures, but the data shows it is not enough for 4K, where the system drops to 12.9 FPS on Ultra. The GPU's 6.175 TFLOPS of FP32 performance is the hard limit, as Rust requires complex shader work for its dynamic lighting and terrain rendering.

The GPU's benchmark scores reflect its mid-range status. It scores 8813 in Passmark G3D, which places it at the 53rd percentile. Its nearest rivals are all older or lower-end cards, including the GTX 570 and GTX 950. The GPU's 14nm process node (from GlobalFoundries) contributes to its 185 W TDP, but the performance per watt is not competitive with newer architectures. In Rust specifically, the GPU's memory bandwidth and pixel throughput are the primary constraints, as evidenced by the steep FPS drops at higher resolutions.

Measured FPS Breakdown

The complete measured dataset provides a clear picture of performance across all resolutions and settings.

At 1920x1080, the system achieves 73.3 FPS on Low, 47.7 FPS on Medium, 43.3 FPS on High, and 32.0 FPS on Ultra. The Low preset is the only one that exceeds 60 FPS, and the drop from Low to Medium is 25.6 FPS, which is the largest single-step penalty in the entire dataset. This suggests that Medium introduces significant shader and texture workloads that the RX 580 cannot handle efficiently.

At 2560x1440, the results are 53.6 FPS on Low, 34.4 FPS on Medium, 28.9 FPS on High, and 21.1 FPS on Ultra. The Low preset remains the only option above 50 FPS, but it is still below the 60 FPS threshold. The gap between Medium and High is only 5.5 FPS, indicating that the GPU is already saturated at this resolution and additional settings changes have diminishing returns.

At 3840x2160, the results are 32.3 FPS on Low, 19.7 FPS on Medium, 15.8 FPS on High, and 12.9 FPS on Ultra. No preset is playable, and the difference between Low and Ultra is 19.4 FPS. The scaling from 1440p Low to 4K Low is a 21.3 FPS drop, which reinforces that the GPU's pixel throughput is the limiting factor. The data shows that 1080p Low is the only configuration that provides a smooth experience, and any attempt to increase quality or resolution will result in frame rates below 50 FPS.
