Rust

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 3080 Ti delivers a performance profile in Rust that is heavily dictated by resolution and graphics preset. At 1080p, the combination is capable of high refresh rates, but the data indicates that the CPU becomes a limiting factor as resolution decreases, preventing the powerful GPU from reaching its full potential. This analysis breaks down the measured FPS data to understand the balance between the processor, graphics card, and the game’s engine.

Resolution Scaling

The measured FPS data reveals a clear pattern of scaling from 1080p to 4K. At the High preset, the average FPS drops from 126 at 1920x1080 to 87 at 2560x1440, a reduction of 39 FPS. Moving to 3840x2160, the average further drops to 52 FPS, a 35 FPS decrease from the 1440p result. This shows that the game is increasingly GPU-bound at higher resolutions, with the RTX 3080 Ti’s rendering load growing substantially.

The scaling between 1080p and 1440p shows a 31% performance drop, which is significant but less severe than the 40% drop observed when moving from 1440p to 4K at the High preset. This non-linear scaling suggests that while the GPU is the primary bottleneck at 4K, the CPU still plays a role in holding back performance at lower resolutions.

At the Low preset, the trend is even more pronounced. The average FPS at 1080p is 155, which drops to 137 at 1440p (an 12% decrease) and then to 91 at 4K (a 34% decrease from 1440p). The relatively small gap between 1080p and 1440p at Low settings indicates that the CPU is the limiting component at these resolutions, as the GPU has enough headroom to render frames quickly. The larger drop at 4K shows the GPU finally becoming the primary constraint.

The Medium preset data, which includes min and max FPS values, reinforces this interpretation. At 1080p Medium, the average is 133 FPS with a min of 113 and max of 153. At 1440p Medium, the average drops to 103 FPS with a min of 88 and max of 119. The 4K Medium result shows an average of 61 FPS with a min of 52 and max of 70. The frame time consistency, as indicated by the min/max range, degrades as resolution increases, which is consistent with the GPU struggling to maintain consistent frame pacing at higher pixel counts.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture. Its base clock is 3.70 GHz and it boosts up to 4.20 GHz. The CPU has an 8 MB shared L3 cache and a dual-channel DDR4 memory interface with a bandwidth of 51.2 GB/s. In synthetic benchmarks, it scores 13593 in Cinebench R23 multi-core and 1919 in single-core. Its Passmark single-thread score is 2653, and its multithread score is 15992.

In Rust, the CPU’s role is most evident when analyzing the 1080p Low preset results. Here, the average FPS of 155 is the highest recorded for this combo, yet the RTX 3080 Ti is capable of much higher frame rates in less CPU-intensive titles. The fact that the FPS does not scale dramatically when moving from Low to Medium at 1080p (155 to 133 FPS) suggests that the CPU is providing a performance ceiling. The 22 FPS difference between these settings indicates that the GPU is doing more work at Medium, but the CPU is still managing to keep up.

The CPU’s percentile rank of 71 among all CPUs indicates that it is a mid-to-upper tier processor. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE, which scores 0.1% higher on average, and the Intel Core i3-14100T, which scores 0.8% higher. This places the 4600G in a competitive position within its class, but it is not a top-tier part.

The combination of a 6-core/12-thread design and a 4.20 GHz boost clock means the CPU can handle the game’s background simulation and entity processing. However, the data shows that at 1080p, the CPU is the primary limiter, as the FPS does not increase proportionally with the GPU’s capabilities. This is a classic sign of a CPU bottleneck, where the processor cannot issue draw calls fast enough to feed the GPU.

How This Combo Ranks

The combination of the AMD Ryzen 5 4600G and NVIDIA GeForce RTX 3080 Ti ranks 1192 out of 3723 tested combinations in Rust. This places the combo in the 68th percentile of all tested systems, meaning it performs better than roughly two-thirds of the tested configurations. This is a strong result, but it also highlights the mismatch between the CPU and GPU.

The RTX 3080 Ti is a high-end GPU with an average benchmark score of 41187, placing it in the 83rd percentile of all GPUs. Its nearest rivals include the AMD Radeon Pro 5300, which scores 0.8% higher, and the NVIDIA GeForce RTX 5070, which scores 2% higher. The CPU, on the other hand, has an average benchmark score of 17507, placing it in the 71st percentile. The gap between the GPU’s high percentile and the CPU’s lower percentile suggests that the CPU is holding back the system from achieving a higher ranking.

If the CPU were a more powerful model, the combo’s rank would likely be higher, as the GPU has the headroom to deliver more frames. The data shows that at 1080p Low, the system only achieves 155 FPS, which is respectable but not exceptional for an RTX 3080 Ti. The ranking reflects this imbalance, as many other combos with more balanced CPU-GPU pairings achieve higher FPS and thus better ranks.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across resolutions and settings. At 1920x1080, the Low preset yields an average of 155 FPS, the Medium preset yields 133 FPS (with a min of 113 and max of 153), the High preset yields 126 FPS, and the Ultra preset yields 96 FPS. The scaling from Low to Ultra at 1080p shows a 38% performance drop, which is significant but still leaves the system playable at all settings.

At 2560x1440, the Low preset averages 137 FPS, the Medium preset averages 103 FPS (with a min of 88 and max of 119), the High preset averages 87 FPS, and the Ultra preset averages 66 FPS. The drop from 1080p to 1440p is more pronounced at higher settings, with High losing 31% performance and Ultra losing 31% as well.

At 3840x2160, the Low preset averages 91 FPS, the Medium preset averages 61 FPS (with a min of 52 and max of 70), the High preset averages 52 FPS, and the Ultra preset averages 39 FPS. The 4K results show that the system struggles to maintain high frame rates at the highest settings, with the Ultra preset falling below 40 FPS. The Medium preset at 4K provides a playable experience with an average of 61 FPS, but the frame time variance (min 52, max 70) suggests some inconsistency.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user’s resolution and performance goals. For 1920x1080, the High preset offers an excellent balance, averaging 126 FPS. This provides a smooth experience on high refresh rate monitors without the visual compromise of the Low preset. The Ultra preset at 1080p yields 96 FPS, which is still very playable and offers the best visual quality.

For 2560x1440, the High preset averages 87 FPS, which is a solid target for most users. The Medium preset offers a higher average of 103 FPS and is a better choice for those prioritizing frame rate over visual fidelity. The Ultra preset at 1440p drops to 66 FPS, which may be acceptable for some, but the High preset provides a better balance.

For 3840x2160, the Medium preset is the recommended choice, with an average of 61 FPS. This is the only 4K setting that maintains an average above 60 FPS. The Low preset offers a higher average of 91 FPS but with significant visual downgrades. The High preset at 4K drops to 52 FPS, which is below the 60 FPS threshold that many consider the minimum for smooth gameplay. The Ultra preset at 39 FPS is not recommended for competitive play.

The data suggests that the Medium preset provides the best overall experience at 4K, while the High preset is the sweet spot at 1080p and 1440p.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is a high-end GPU based on the Ampere architecture. It features 12 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 912.4 GB/s. The GPU has 10240 shading units, 320 texture mapping units, and 112 raster output units. Its base clock is 1365 MHz with a boost clock of 1665 MHz. The GPU’s FP32 performance is 34.10 TFLOPS, and its texture rate is 532.8 GTexel/s.

In Rust, the GPU’s role is most apparent at higher resolutions and settings. The 12 GB of VRAM is sufficient for the game’s textures at all tested settings, as the data shows no signs of memory-related stuttering. The GPU’s massive memory bandwidth of 912.4 GB/s ensures that texture streaming is not a bottleneck, even at 4K.

The RTX 3080 Ti’s percentile rank of 83 among all GPUs indicates it is a top-tier part. Its nearest rival, the NVIDIA GeForce RTX 5070, scores 2% higher on average, while the AMD Radeon Pro 5300 scores 0.8% higher. This places the 3080 Ti in a competitive position, but its performance in Rust is ultimately limited by the CPU at lower resolutions.

At 1080p, the GPU is often idle, waiting for the CPU to deliver frames. This is evident from the small FPS difference between the Low and High presets at 1080p (155 vs 126 FPS), which is only a 19% drop despite the significantly higher rendering workload. At 4K, however, the GPU is fully utilized, and the FPS scales more predictably with settings, dropping from 91 FPS at Low to 39 FPS at Ultra. The data confirms that the RTX 3080 Ti is a powerful GPU that can handle Rust at 4K, but its full potential is only realized when paired with a stronger CPU.
