Rust

AMD Ryzen 5 4600G paired with the AMD Radeon RX 9070 presents a stark contrast in generational capability within a single system. The data shows a CPU built on the Zen 2 architecture from the 4000 series, alongside a GPU based on the flagship RDNA 4.0 architecture. This combination yields a fascinating set of benchmark results in Rust, where the measured frames per second reveal a system that is heavily dictated by resolution and the specific workload demands of the survival title. The following analysis breaks down the performance metrics, component roles, and optimal configurations based solely on the observed data.

Resolution Scaling

The measured FPS data for this combination demonstrates a clear and predictable scaling pattern as resolution increases, but the rate of that scaling tells a significant story about component bottlenecks. At 1080p with Low settings, the combo achieves an average of 155 FPS. Moving to 1440p Low, the average drops to 137 FPS, a reduction of 18 FPS (approximately 12%). However, the most dramatic shift occurs when moving from 1440p to 4K at Low settings, where the average FPS plummets to 86, a substantial 51 FPS (37%) decrease. This steep drop at 4K indicates that the rendering load is finally overwhelming the graphics processor, even on a modern RDNA 4.0 card.

The pattern becomes even more pronounced when examining the High settings preset. At 1080p High, the system produces 120 FPS. At 1440p High, this falls to 83 FPS, a 31% reduction. The 4K High result drops further to 49 FPS, which is a 41% reduction from the 1440p figure and only 41% of the 1080p performance. This suggests that while the RX 9070 has immense raw power, the Ryzen 5 4600G's Zen 2 architecture may be limiting the frame rate at lower resolutions where the CPU has to feed frames faster. The fact that 1080p Low (155 FPS) is not significantly higher than 1080p Medium (133 FPS) or High (120 FPS) points to a CPU limitation in these scenarios; the GPU is capable of more, but the processor cannot keep up with the instruction throughput required for high-refresh-rate gaming in Rust.

The 4K Ultra setting yields just 37 FPS, while 4K Medium produces 58 FPS. The gap between Low and Ultra at 4K is 49 FPS, which is nearly identical to the frame rate itself. This indicates that at 4K, the GPU is the definitive limiting component, as the scaling from Low to Ultra directly reflects the increased pixel and shader workload. In contrast, the scaling from Low to Ultra at 1080p is only 64 FPS (155 to 91), which is a smaller absolute delta and further supports the theory that the CPU is capping performance in the lower resolution, lower settings domain.

FAQ

Q: What is the maximum average FPS achievable with this CPU and GPU combination in Rust?

A: The highest measured average frame rate is 155 FPS, which occurs at 1920x1080 resolution with Low settings.

Q: How does the system perform at 4K resolution with the highest visual fidelity?

A: At 3840x2160 resolution with Ultra settings, the system produces an average of 37 FPS, with a minimum observed of 49 FPS on Medium settings suggesting potential frame pacing issues at higher presets.

Q: Is the AMD Ryzen 5 4600G a limiting factor at 1080p?

A: Benchmark results indicate a CPU bottleneck at 1080p. The average FPS difference between Low (155 FPS) and High (120 FPS) is only 35 FPS, and the jump to Medium (133 FPS) shows less scaling than expected from a GPU-bound system, suggesting the processor's Zen 2 cores are the primary constraint.

Q: What is the performance delta between 1080p and 4K at High settings?

A: The average FPS drops from 120 at 1920x1080 to 49 at 3840x2160, representing a 71 FPS (59%) decrease. This substantial drop highlights the massive pixel throughput demand at 4K.

Q: How does this combo rank among other tested systems in this game?

A: The combination ranks 1275th out of 3723 tested combos, placing it in the upper third of all systems tested for Rust.

Q: Does the Radeon RX 9070's 16 GB of VRAM appear to be a limitation in the measured results?

A: The data does not indicate a VRAM capacity limitation. The performance scaling from Low to Ultra at 4K shows a consistent degradation in FPS, which is characteristic of GPU compute limits rather than memory exhaustion, as the card is well-equipped with 16 GB of GDDR6 memory.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Renoir, and fabricated on a 7 nm process. Its benchmark scores paint a picture of a mid-range CPU that is now a few generations old. In Cinebench R23, it scores 13593 points in multi-core and 1919 points in single-core tests. The single-core performance of 1919 is a critical metric for gaming, as many titles, including Rust, rely heavily on single-threaded performance for game logic and physics. The 3DMark scores show a single-thread score of 726 and a max-thread score of 4889, indicating that the processor's performance scales reasonably well with additional threads but its individual core strength is its limiting factor.

In the context of the measured Rust results, the CPU's role is most evident at 1080p. The average FPS at 1080p Low is 155, but this does not scale dramatically to 133 FPS at Medium or 120 FPS at High. This plateau suggests that the CPU cannot generate frames faster than the 155 FPS ceiling, regardless of the GPU's capability. The processor's 8 MB of shared L3 cache and dual-channel DDR4 memory support (with 51.2 GB/s bandwidth) are adequate but not exceptional for feeding a high-end GPU. The 3DMark 16-thread score of 4863 further indicates that while the CPU has sufficient multi-threading for modern games, its per-core performance is what keeps it from pushing frame rates higher in CPU-bound scenarios.

The comparison to its nearest rivals shows the 4600G sits in a tight performance cluster. It is 0.1% faster than the AMD Ryzen 3 PRO 5355GE, with an average score of 17482 vs 17507, and 0.6% faster than the Intel Core 7 150U. However, it is 0.6% slower than the AMD Ryzen 3 8300GE and 0.8% slower than the Intel Core i3-14100T. This places the 4600G in a competitive position for its class, but the data shows it is not a top-tier performer. In Rust, this mid-pack CPU performance translates directly to the observed frame rate ceilings, particularly at lower resolutions where the CPU is the primary bottleneck.

How This Combo Ranks

The combination of the Ryzen 5 4600G and the Radeon RX 9070 achieves a rank of 1275 out of 3723 tested combinations in Rust. This places the system in the 66th percentile of all tested hardware pairings, meaning it outperforms roughly two-thirds of the systems tested. This rank is a direct reflection of the balance between the CPU and GPU. The GPU is a modern, high-performance part, evidenced by its 3DMark Steel Nomad score of 6290 and its percentile rank of 69 among all GPUs. In contrast, the CPU's percentile rank is 71 among all CPUs, which is slightly higher, but its absolute performance in gaming-specific workloads is more limited.

The rank of 1275 suggests that while the RX 9070 is capable of delivering high frame rates, the Ryzen 5 4600G is holding the system back from reaching the top echelons of the ranking chart. Combos that rank higher likely utilize CPUs with stronger single-core performance, which is critical for Rust's engine. The fact that this combo still ranks in the top 34% confirms the GPU's raw power, which can compensate for CPU limitations at higher resolutions. However, the data indicates that a user with this combo would see significant benefits from a CPU upgrade, as the GPU is underutilized at 1080p. The 4K results, where the rank would likely be higher due to GPU-bound performance, show the system can still compete, but the overall score is dragged down by the 1080p and 1440p scenarios where the CPU struggles.

GPU Role

The AMD Radeon RX 9070 is a powerhouse based on the RDNA 4.0 architecture, built on a 4 nm process with 53,900 million transistors. It features 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of bandwidth. The card's boost clock is 2520 MHz, with a game clock of 2070 MHz. These specifications position the GPU as a high-end part, capable of handling 4K gaming with high settings. Its 3DMark Steel Nomad score of 6290 and Passmark G3D score of 25381 confirm its performance class, placing it in the 69th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 2080 SUPER, has a similar average score of 24170, with the RX 9070 being 1.2% faster.

In the measured Rust results, the GPU's role becomes dominant as resolution increases. At 4K, the performance scaling is directly proportional to the settings preset. The average FPS drops from 86 at Low to 58 at Medium, 49 at High, and 37 at Ultra. This clear gradient indicates that the GPU is the limiting component at this resolution, and its 16 GB of VRAM is sufficient to handle the texture and geometry data without causing a memory-related crash or stutter (the minimum FPS of 49 at 4K Medium is notably lower than the average of 58, but this could be due to scene complexity). The GPU's 128 ROPs and 3584 shading units are being fully utilized at 4K, as the rendering pipeline is saturated.

The GPU's role is less defined at 1080p, where the data suggests it is not the bottleneck. The card is capable of producing well over 155 FPS, but the CPU prevents it from doing so. This is a classic case of a high-end GPU being paired with a lower-end CPU. The RX 9070's 644.6 GB/s of memory bandwidth is more than enough for Rust at 1080p, but the processor cannot supply the draw calls and game state updates quickly enough. The GPU's performance at 1440p (137 FPS Low, 83 FPS High) shows a balanced workload, where the GPU is starting to become more relevant, but the CPU is still contributing to the frame time.

Measured FPS Breakdown

The following is a complete breakdown of the average FPS measurements for the AMD Ryzen 5 4600G + AMD Radeon RX 9070 combination in Rust.

1920x1080:

• Low: Average 155 FPS.
• Medium: Average 133 FPS, with a minimum of 113 and maximum of 153 FPS.
• High: Average 120 FPS.
• Ultra: Average 91 FPS.

2560x1440:

• Low: Average 137 FPS.
• Medium: Average 98 FPS, with a minimum of 83 and maximum of 113 FPS.
• High: Average 83 FPS.
• Ultra: Average 63 FPS.

3840x2160:

• Low: Average 86 FPS.
• Medium: Average 58 FPS, with a minimum of 49 and maximum of 67 FPS.
• High: Average 49 FPS.
• Ultra: Average 37 FPS.

The data reveals a few key insights. First, the step from Low to Medium at 1080p costs 22 FPS, while the step from Medium to High costs only 13 FPS. This suggests that the Medium preset is a sweet spot for visual quality versus performance at this resolution. Second, the minimum FPS values for the Medium presets (113 at 1080p, 83 at 1440p, and 49 at 4K) are significantly lower than the averages, pointing to potential stutters in complex scenes. Finally, the 4K Ultra setting at 37 FPS is barely playable, while 4K Low at 86 FPS is smooth, indicating that users with 4K displays must sacrifice significant visual fidelity to achieve playable frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends largely on the user's display resolution and performance targets.

For 1920x1080 displays: The High preset offers the best balance, delivering 120 FPS. The Medium preset provides a higher 133 FPS but with a lower minimum of 113 FPS. For users with 144Hz monitors, the Low preset at 155 FPS is necessary to fully utilize the refresh rate, but the visual sacrifice may not be worth the 35 FPS gain over High. The Ultra preset at 91 FPS is smooth but introduces a 29 FPS penalty over High for marginal visual improvements, making it less desirable.

For 2560x1440 displays: The High preset at 83 FPS is the recommended choice for a smooth experience, as it sits comfortably above the 60 FPS threshold. The Medium preset at 98 FPS is also viable and offers higher frame rates, but the minimum of 83 FPS suggests potential dips. The Low preset at 137 FPS is ideal for high-refresh-rate 1440p monitors, while the Ultra preset at 63 FPS is playable but leaves little headroom for demanding scenes.

For 3840x2160 displays: The Low preset at 86 FPS is the only setting that provides a truly smooth experience. The Medium preset at 58 FPS is playable but not ideal for fast-paced action, and the High preset at 49 FPS and Ultra preset at 37 FPS are not recommended for competitive play. Users on 4K should prioritize the Low or Medium presets to avoid the severe frame rate drops seen at higher settings. The data clearly shows that this combo is not suited for 4K High or Ultra gaming in Rust, as the average FPS falls below the 60 FPS threshold, and the minimum FPS can dip to 49 FPS, which would cause noticeable stutter.
