Rust

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 4090 produces a curious benchmark profile in Rust, where the CPU’s modest specifications create a noticeable bottleneck for the GPU’s immense rendering power. The measured frames per second across resolutions and presets reveal a system that is consistently playable but never fully unlocks the graphics card’s potential, particularly at lower resolutions where the CPU’s limits become the primary constraint.

Settings Recommendations

The benchmark data indicates that the Medium preset offers the most balanced experience across all tested resolutions, providing a significant jump in frame rate over High settings while maintaining visual fidelity above the Low baseline. At 1920x1080, Medium delivers 135.1 FPS, which is 6.0 FPS higher than High’s 129.1 and only 21.8 FPS below Low’s 156.9. This positions Medium as the sweet spot for competitive play, as the frame rate remains well above the 120 FPS threshold commonly associated with smooth motion.

At 2560x1440, the Medium preset’s advantage becomes even more pronounced. The measured 118.2 FPS at Medium is 7.9 FPS higher than High’s 110.3 and only 20.5 FPS below Low’s 138.7. This suggests that Medium allows the hardware to maintain a strong performance margin without the visual compromises of Low, which often strips away essential details in a survival game where spotting distant players or resources is critical.

For 4K gaming, the Medium preset’s 85.3 FPS is the most practical choice, as it remains comfortably above the 60 FPS playability floor. High drops to 74.6 FPS, and Ultra falls to 53.7 FPS, which dips below the smoothness threshold. Low at 117.2 FPS is the only preset that fully saturates high-refresh-rate 4K displays, but the visual downgrade may be too severe for a game that relies on environmental awareness. The data clearly shows that Ultra is not recommended at any resolution, as it consistently produces the lowest frame rates: 112.5 at 1080p, 96.1 at 1440p, and 53.7 at 4K.

GPU Role

The NVIDIA GeForce RTX 4090 brings an enormous amount of raw graphics horsepower to this pairing, with a boost clock of 2520 MHz and a 24 GB GDDR6X memory pool operating on a 384-bit bus. The memory bandwidth of 1.01 TB/s is exceptional, yet the benchmark results show that this capability is not being fully utilized in Rust. At 1080p Low, the system reaches 156.9 FPS, but this is only 27.8 FPS higher than the 4K Low result of 117.2 FPS. This modest scaling suggests that the CPU is limiting the GPU’s output even at lower resolutions.

The GPU’s massive shading unit count of 16384 and texture mapping units of 512 should theoretically dominate any modern title, but the measured frame rates at 4K Ultra (53.7 FPS) indicate that even this flagship card cannot overcome the CPU bottleneck in the most demanding settings. The 24 GB VRAM is far more than Rust requires, and the 128 ray tracing cores and 512 tensor cores provide capabilities that the game does not heavily leverage. The GPU’s benchmark percentile of 91 places it in the top tier of graphics cards, yet its performance here is constrained by the processor.

How This Combo Ranks

The combination of the Ryzen 5 4600G and RTX 4090 ranks 307th out of 1717 tested combos in Rust, placing it in the 82nd percentile of all pairings. This is a surprisingly high rank given the CPU’s limitations, but it reflects the enormous performance headroom that the RTX 4090 provides even when partially bottlenecked. The CPU itself sits at the 75th percentile of all processors, with an average benchmark score of 17489, while the GPU’s average benchmark score of 66473 places it at the 91st percentile of all graphics cards.

The rank of 307 suggests that many other combos in the database achieve higher frame rates, likely those pairing the RTX 4090 with more powerful processors. The data implies that the RTX 4090 is the dominant factor in this ranking, as the CPU’s performance is comparatively modest. The gap between this combo and the top-ranked pairings likely stems from the CPU’s inability to feed the GPU enough data at lower resolutions, where the processor’s 6 cores and 12 threads become the limiting factor.

FAQ

Q: What frame rate can this combo achieve at 1080p with High settings?

A: The measured average FPS at 1920x1080 with High settings is 129.1, which provides a smooth experience for most gameplay scenarios.

Q: Is the Ultra preset viable at 4K resolution?

A: No, the 4K Ultra preset produces an average of 53.7 FPS, which falls below the 60 FPS threshold typically considered necessary for fluid gameplay.

Q: How does the CPU’s benchmark score compare to its nearest rivals?

A: The Ryzen 5 4600G scores 17489 on average, which is 0.1% lower than the Intel Core i5-12450H and 0.8% higher than the Intel Core i3-14100T.

Q: Does the GPU’s memory bandwidth impact performance in Rust?

A: The RTX 4090’s 1.01 TB/s bandwidth is substantial, but the benchmark results suggest the CPU, not memory bandwidth, is the limiting factor, as frame rates scale more with resolution than with memory-intensive settings.

Q: What is the best resolution for maximizing frame rate?

A: At 1920x1080 with Low settings, the combo achieves 156.9 FPS, which is the highest measured average across all configurations in the data.

A: This pairing ranks 307th out of 1717 tested combos, placing it in the top 18% of all configurations tested in Rust.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the CPU-bound nature of this pairing. At Low settings, the drop from 156.9 FPS at 1080p to 117.2 FPS at 4K represents a 39.7 FPS decrease, or roughly 25% lower performance. This relatively small penalty for a 4x increase in pixel count indicates that the GPU is not being pushed to its limits at lower resolutions, as the CPU is already maxed out. The RTX 4090 has ample headroom to render more pixels, but the processor cannot provide enough draw calls and game logic updates to keep the frame rate higher.

The scaling pattern is more pronounced at higher settings. At Ultra, the drop from 112.5 FPS at 1080p to 53.7 FPS at 4K is a 58.8 FPS decrease, or 52% lower performance. This larger penalty suggests that at higher settings, the GPU begins to become more of a limiting factor, as the increased visual complexity requires more shading and texture work that taxes the graphics card. However, even at 4K Ultra, the frame rate remains above 50 FPS, which reflects the GPU’s raw power. The data shows that the limiting component shifts from CPU at low resolutions to a more balanced load at 4K, where both components contribute to the final frame rate.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its 8 MB of shared L3 cache and dual-channel DDR4 memory support provide a solid foundation for gaming, but the benchmark results in Rust indicate that its single-threaded performance is the primary constraint. The CPU scores 726 in 3DMark single-thread testing and 1919 in Cinebench R23 single-core, which are modest figures compared to modern high-end processors.

In Rust, which is known for its heavy CPU usage due to the large number of entities and player interactions, the 4600G’s performance is the bottleneck at lower resolutions. The data shows that at 1080p Low, the system achieves 156.9 FPS, but the CPU’s max-thread benchmark score of 4889 in 3DMark suggests it is working at its limit. The processor’s 75th percentile ranking among all CPUs confirms that it is above average, but not exceptional. The nearest rivals show a tight clustering: the AMD Ryzen 3 PRO 5355GE scores 17482 (0% delta), the Intel Core i5-12450H scores 17475 (0.1% higher), and the Intel Core i3-14100T scores 17636 (0.8% higher). This indicates that the 4600G is competitively positioned among its peers, but none of these processors would be considered high-end for pairing with an RTX 4090.

The CPU’s 65 W TDP and 7 nm process node contribute to its efficiency, but the benchmark data suggests that in Rust, the processor’s 4.20 GHz boost clock cannot compensate for its architectural limitations. The 3DMark 2-thread score of 1430 and 4-thread score of 2732 reveal that multi-threaded scaling is present but not exceptional. This explains why the frame rates at 1080p do not exceed 156.9 FPS, as the CPU’s per-core performance caps the system’s output. The GPU is clearly capable of much higher frame rates, as evidenced by its 91st percentile ranking, but the CPU’s 75th percentile performance holds the pairing back.
