Rust

The AMD Ryzen 5 4600G and AMD Radeon RX 9060 pairing in Rust presents a study in asymmetry. The CPU is a 6-core, 12-thread Zen 2 part with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its 8 MB of shared L3 cache is modest by modern standards, and its 65 W TDP suggests a focus on efficiency over raw throughput. The GPU, in contrast, is a modern RDNA 4.0 part based on the Navi 44 chip. It is built on a 4 nm process and features a substantial 8 GB of GDDR6 memory on a 128-bit bus, delivering a memory bandwidth of 288.0 GB/s. Its boost clock reaches 2990 MHz, with a game clock of 2400 MHz.

The measured frame rates in Rust reveal that this CPU is the primary constraint at lower resolutions, but the GPU takes over as the bottleneck when resolution climbs. At 1920x1080 with Low settings, the combo achieves 151 FPS, a figure that is more than double the 65 FPS seen at Ultra settings. This wide spread indicates that the system is capable of high throughput when the load is light, but the CPU's single-thread performance, which sits at a 3dmark single-thread score of 726 and a Cinebench R23 single-core score of 1919, limits the ceiling when the game's simulation and entity logic become more demanding. The 6-core, 12-thread configuration is adequate for Rust's multi-threaded nature, but it is not a high-end part; its average benchmark score of 17507 places it at the 71st percentile of all CPUs, and its nearest rival, the AMD Ryzen 3 PRO 5355GE, is just 0.1% behind in average score.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 5 4600G's specifications paint a picture of a solid, mid-range workhorse from the 4000 series. With 6 cores and 12 threads, it can handle multiple tasks, but Rust is known for its heavy server-side and client-side simulation, which often scales with single-thread performance. The CPU's architecture is Zen 2, fabricated on a 7 nm TSMC process, and it supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. This memory bandwidth is a critical factor in Rust, where the game world is densely packed with entities and the CPU must constantly stream data.

Benchmark data shows the chip's strengths and weaknesses. Its Cinebench R23 multicore score of 13593 is respectable, indicating that it can leverage its 12 threads effectively for rendering or compilation tasks. However, its single-core performance is less impressive, with a Geekbench single-core score of 1460. In Rust, this means that when the game engine is bottlenecked on a single main thread—often the case when many players are nearby or when the server is processing complex interactions—the 4600G will struggle to keep up with faster chips. The data confirms this: at 1080p Low, the FPS is 151, but at 1080p Ultra, it drops to 65. This 86 FPS drop is not purely a GPU load issue; it suggests the CPU is unable to feed the GPU with enough frames when the game's simulation complexity increases with higher settings that affect entity counts and draw distances.

The CPU's nearest rivals in the benchmark database include the Intel Core i3-14100T, which has a 0.8% higher average score, and the AMD Ryzen 3 8300GE, which is 0.6% higher. These are all budget-oriented parts, indicating that the 4600G sits at the entry level of modern desktop performance. In the context of this GPU pairing, the CPU's limitations become apparent. For instance, the 3dmark 16-thread score of 4863 is only slightly higher than the 8-thread score of 4138, showing that scaling beyond 8 threads delivers diminishing returns. This is typical for a 6-core part, but it also means that the CPU cannot fully utilize its thread count to overcome single-thread bottlenecks in Rust.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Radeon RX 9060 is the clear performance leader in this pairing. Its 8 GB of GDDR6 memory is sufficient for Rust at 1080p and 1440p, but the 128-bit bus width and 288.0 GB/s bandwidth are modest. The GPU's pixel rate of 191.4 GPixel/s and texture rate of 334.9 GTexel/s are strong on paper, and its FP32 performance of 21.43 TFLOPS places it firmly in the mid-range category. Its average benchmark score of 16014 puts it at the 59th percentile of all GPUs, and its nearest rival, the NVIDIA GeForce RTX 3060 Ti, has an average score that is only 0.7% higher. The AMD Radeon RX 7700 is 1% ahead, and the Radeon R9 370X is 1% behind.

In Rust, the GPU's role becomes dominant at higher resolutions. At 3840x2160 with Ultra settings, the combo produces just 27 FPS, which is unplayable. At 1440p Ultra, the average FPS is 45, still below the 60 FPS threshold. The GPU's clock speeds are high—boost 2990 MHz and game 2400 MHz—which helps at lower resolutions. At 1080p Low, the combo hits 151 FPS, but this is largely CPU-bound, as the GPU has plenty of headroom. The data shows a clear pattern: when the resolution increases, the GPU's memory bandwidth and compute resources become the limiting factor. The 8 GB VRAM is adequate for 1080p and 1440p, but at 4K, the game's texture streaming and geometry demand more than the 128-bit bus can efficiently deliver, leading to the sharp FPS drops observed.

The GPU's DirectX 12 and Vulkan scores—3322 in 3dmark Steel Nomad and 39476 in Geekbench Vulkan—indicate it is well-optimized for modern APIs. However, Rust's engine can be sensitive to driver overhead, and the data suggests that the GPU's raw power is not the issue; rather, it is the memory subsystem that holds it back at 4K. The 288.0 GB/s bandwidth is a bottleneck when pushing 3840x2160, resulting in the 35 FPS average on High settings and 41 FPS on Medium, which are both below the 60 FPS target.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS across resolutions tells a clear story of a system that transitions from CPU-bound to GPU-bound. At 1920x1080 Low settings, the combo averages 151 FPS. This is a high number, but it is not the GPU's limit; rather, it is the CPU's limit. The CPU's single-thread performance, as evidenced by its Passmark single-thread score of 2653, cannot push more frames in this scenario. When moving to 2560x1440 Low, the average drops to 104 FPS, a 47 FPS decrease. This is a significant drop, but it is not proportional to the pixel count increase (which is roughly 1.78 times). This indicates that the system is still partially CPU-bound at 1440p, but the GPU is starting to take on more load. At 3840x2160 Low, the average FPS is 62, another 42 FPS drop. This is a more dramatic decline, and it clearly shows the GPU becoming the primary bottleneck, as the pixel count is now 2.25 times that of 1440p.

Looking at the Ultra settings, the pattern is even more pronounced. At 1080p Ultra, the average is 65 FPS. At 1440p Ultra, it is 45 FPS, and at 4K Ultra, it is 27 FPS. The drop from 1080p to 1440p is 20 FPS (a 31% decrease), and from 1440p to 4K is 18 FPS (a 40% decrease). These percentages are higher than the Low settings drops, which suggests that the GPU is heavily taxed by the Ultra settings, which likely include higher draw distances, more complex shadows, and higher texture quality. The 8 GB VRAM may also be a factor at 4K Ultra, as the game could be swapping textures, further reducing performance. This data confirms that at 1080p, the Ryzen 5 4600G is the limiting factor, and at 4K, the Radeon RX 9060 is the limiting factor. The crossover point is somewhere between 1440p and 4K, where the system becomes balanced.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Ryzen 5 4600G and the RX 9060 achieves a rank of 1665 out of 2953 tested combos in Rust. This places it in the 56th percentile of all systems tested, which is a below-average position. This is a surprising result given the GPU's mid-range standing, but it is explained by the CPU's limitations. The CPU's percentile rank of 71 is higher than the GPU's rank of 59, but in Rust, the CPU's single-thread performance is more critical than its multi-thread score. The data shows that the combo is not competitive with systems that pair the RX 9060 with a faster CPU.

The rank of 1665 indicates that there are 1288 combos that perform worse, but there are 1664 combos that perform better. This is a middle-of-the-pack result. The nearest rivals for the CPU and GPU individually do not provide direct combo comparisons, but the deltaPct values give a sense of relative performance. For example, if the CPU were swapped for an Intel Core 7 150U (which has a 0.6% higher average score), the overall combo performance would likely be similar, as the GPU would still be the bottleneck at higher resolutions. However, if the GPU were swapped for an RTX 3060 Ti (which is 0.7% faster), the combo might see a slight improvement at 4K, but the CPU would still limit 1080p performance. The rank of 1665 suggests that this pairing is not well-balanced for Rust, as the CPU holds back the GPU's potential at lower resolutions, and the GPU's memory bandwidth limits 4K performance.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the system's capabilities. At 1920x1080, the combo produces the following average FPS: Low settings at 151 FPS, Medium settings at 102 FPS (with a min of 86 and max of 117), High settings at 86 FPS, and Ultra settings at 65 FPS. The variance between Low and Ultra is substantial, with Ultra delivering less than half the performance of Low. This suggests that the settings have a significant impact on the CPU and GPU load. The Medium setting's min FPS of 86 is close to the High average of 86, indicating that frame pacing may be inconsistent.

At 2560x1440, the average FPS drops: Low at 104 FPS, Medium at 70 FPS (min 59, max 80), High at 59 FPS, and Ultra at 45 FPS. The drop from 1080p to 1440p is noticeable, but the system remains playable on Medium and Low settings. The High setting at 59 FPS is just below the 60 FPS target, and Ultra at 45 FPS is not ideal for a competitive game. At 3840x2160, the performance is marginal: Low at 62 FPS, Medium at 41 FPS (min 35, max 47), High at 35 FPS, and Ultra at 27 FPS. Only the Low setting is playable at 4K, and even then, it is close to the edge of smoothness. The Medium setting's min FPS of 35 shows significant dips that would be noticeable in gameplay.

The data also shows that the difference between High and Ultra settings is consistent across resolutions. At 1080p, the drop from High to Ultra is 21 FPS (86 to 65). At 1440p, it is 14 FPS (59 to 45), and at 4K, it is 8 FPS (35 to 27). This suggests that Ultra settings add a fixed amount of GPU load, which becomes less impactful as the resolution increases, because the GPU is already saturated. This is a classic sign of a GPU bottleneck at higher resolutions.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience depends on the target resolution and the user's preference for frame rate versus visual fidelity. At 1920x1080, the High settings preset provides an average of 86 FPS, which is smooth and responsive for a survival game. The Ultra preset drops to 65 FPS, which is still playable but may not be worth the visual gain, especially if the user is sensitive to frame drops. The Medium preset at 102 FPS is a good alternative for users who want a higher frame rate, but the visual difference between Medium and High is often negligible in Rust. The data suggests that High is the sweet spot for 1080p, as it offers a good balance of visual quality and performance.

At 2560x1440, the High preset averages 59 FPS, which is just below the 60 FPS target. This is acceptable for a slower-paced game like Rust, but the Low preset at 104 FPS is a safer choice for maintaining a high frame rate. The Medium preset at 70 FPS (min 59) is also a viable option, as it provides a smoother experience than High while still looking decent. The Ultra preset at 45 FPS is not recommended, as the frame rate is too low for a game where quick reactions can be necessary. For 1440p, the Medium preset is the best choice, as it delivers a stable 70 FPS average with acceptable visuals.

At 3840x2160, the data is clear: only the Low preset at 62 FPS is playable. The Medium preset at 41 FPS (min 35) is risky, as the minimum FPS can dip below 40, which can cause stuttering. The High and Ultra presets at 35 FPS and 27 FPS, respectively, are not viable for a competitive or immersive experience. Therefore, for 4K, the Low preset is the only recommendation. This is a significant compromise, but it is the only way to achieve a playable frame rate with this hardware combination. Users with a 4K monitor should consider dropping to 1440p to unlock higher settings and a more stable frame rate.
