Rust

The AMD Ryzen 7 5700G paired with the NVIDIA GeForce RTX 3080 Ti delivers a robust, high-refresh-rate experience in Rust, though the game’s demands scale steeply with resolution and preset. Benchmark results show a system that is overwhelmingly GPU-bound at lower resolutions, where the 8-core/16-thread CPU is sufficient to keep the RTX 3080 Ti fed, but which transitions to a more balanced load as pixel count rises. The measured FPS data reveals that this combination is capable of 4K playable framerates, but only at lower presets, while 1440p and 1080p offer ample headroom for competitive or visually rich settings.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, clearly indicating that the GPU becomes the primary limiting factor at higher resolutions. At the High preset, the average FPS falls from 127 at 1920x1080 to 87 at 2560x1440, a reduction of 40 FPS (or roughly 31%), and then further to 52 at 3840x2160, which is a 75 FPS drop (or about 59%) from the 1080p baseline. This steep decline is characteristic of a game where rendering load scales heavily with pixel count, and the RTX 3080 Ti’s 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are pushed hard at 4K.

The scaling pattern is consistent across all presets. With Low settings, the average FPS goes from 192 at 1080p to 154 at 1440p and then to 91 at 4K. The delta between 1440p and 4K is 63 FPS, a 41% drop, which is nearly identical to the 42% drop seen between 1080p and 1440p. This linear-like scaling suggests that at Low preset, the game is almost entirely GPU-limited, as the CPU’s workload is relatively light, and the raw fill-rate demands of 4K (roughly four times the pixels of 1080p) directly translate into lower FPS.

For the Medium preset, the data shows 150 FPS at 1080p, 103 FPS at 1440p, and 61 FPS at 4K. The jump from 1080p to 1440p costs 47 FPS, while moving from 1440p to 4K costs 42 FPS. This is interesting, as it suggests that at Medium settings, the CPU begins to play a more significant role at 1080p, where the 150 FPS ceiling is likely approaching the limit of what the Ryzen 7 5700G can sustain with its 3.80 GHz base and 4.60 GHz boost clocks. At 4K, the GPU is clearly the bottleneck, as evidenced by the fact that the FPS drops below the 60 FPS target, averaging 61 with a minimum of 52.

The Ultra preset shows the most dramatic scaling, with 96 FPS at 1080p, 66 FPS at 1440p, and just 39 FPS at 4K. This represents a 57 FPS drop (59%) from 1080p to 4K, which is the largest absolute and percentage decline among all presets. The results indicate that Ultra settings in Rust are extremely demanding on the GPU, and the RTX 3080 Ti, while a high-end card in the 83rd percentile of all GPUs, is not enough to maintain smooth gameplay at 4K with everything maxed out. The data strongly suggests that for 4K gaming, users should expect to dial back settings to Medium or Low to stay above 60 FPS.

Settings Recommendations

Based on the measured FPS rows, the optimal preset depends heavily on the target resolution and desired framerate. For 1920x1080, all presets are playable, but the sweet spot for a high-refresh experience is the High preset, which delivers 127 FPS average. While Low offers 192 FPS and Medium offers 150 FPS, the jump to High provides a significantly better visual experience for only a 23 FPS cost relative to Medium. Ultra at 1080p yields 96 FPS, which is still smooth, but the performance hit from High to Ultra is 31 FPS, making High the better balance for most users who want a mix of quality and speed.

At 2560x1440, the Medium preset emerges as the best recommendation, with an average of 103 FPS and a minimum of 88 FPS. This ensures that framerates stay comfortably above the 60 FPS threshold, even in demanding scenes. High settings at 1440p drop to 87 FPS average, which is still playable but leaves less headroom for dips in busy areas. Ultra at 1440p falls to 66 FPS, which is borderline, and the data shows a 21 FPS penalty over Medium. The 1440p Medium setting is the clear choice for a smooth, high-quality experience.

For 3840x2160, the situation becomes more constrained. The only preset that achieves an average above 60 FPS is Low, with 91 FPS. Medium at 4K averages 61 FPS with a minimum of 52, which means it will dip below 60 FPS in some scenes, potentially causing noticeable stutter. High at 4K averages 52 FPS, and Ultra averages just 39 FPS, both of which are not ideal for a smooth experience. The data recommends Low for 4K if framerate is the priority, or Medium if the user can tolerate occasional dips below 60 FPS. The measured results clearly show that Ultra is not viable at 4K for this combination.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, and the data shows it is the primary bottleneck at higher resolutions. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, yielding a massive 912.4 GB/s of bandwidth. This is crucial for Rust, which is known for its large, dense worlds and heavy texture streaming. The 12 GB capacity is sufficient for 4K textures, as evidenced by the playable framerates at Medium settings, but the data suggests that the card’s raw compute power, rated at 34.10 TFLOPS FP32, is the limiting factor at Ultra presets.

The GPU’s clock behavior, with a base of 1365 MHz and a boost of 1665 MHz, is typical for the Ampere architecture. The benchmark scores reflect its high-end positioning, with a Passmark G3D score of 26896 and a percentile ranking of 83 among all GPUs. Its nearest rivals include the AMD Radeon Pro 5300 (0.8% higher score) and the NVIDIA Tesla M40 24 GB (1.2% lower), but these are professional or older cards; in gaming, the RTX 3080 Ti is clearly a top-tier consumer part. The 3DMark Steel Nomad DX12 score of 5077 further confirms its capability in modern API workloads.

The GPU’s role in the measured FPS is evident in the scaling patterns. At 1080p, the RTX 3080 Ti is often underutilized, as the CPU can keep up with its output, leading to high framerates (e.g., 192 FPS on Low). However, at 4K, the GPU is saturated, and the FPS drops to levels that suggest it is working at or near its maximum capacity. The 350 W TDP and suggested 750 W power supply indicate that this is a power-hungry card, but the data does not include power consumption metrics, so performance per watt cannot be assessed here. The GPU’s 80 RT cores and 320 Tensor cores are present, though Rust’s implementation of ray tracing is not detailed in the measured data, so their impact on the FPS results is unknown.

How This Combo Ranks

In the benchmark database, this specific combination of AMD Ryzen 7 5700G and NVIDIA GeForce RTX 3080 Ti ranks 969th out of 3723 tested combos in Rust. This places it in the top 26% of all configurations, which is a solid result, given that the CPU is not a top-tier gaming processor. The Ryzen 7 5700G has a 79th percentile ranking among all CPUs, and its average benchmark score of 27051 is slightly below its nearest rival, the Intel Core i9-9900K, by 0.2%. The GPU, on the other hand, is in the 83rd percentile, with an average score of 41187.

The combo rank of 969 out of 3723 suggests that while the GPU is powerful enough to drive high framerates, the CPU’s performance ceiling may prevent the system from achieving the absolute top tier of results. The data shows that the CPU’s single-thread performance, with a Cinebench R23 single-core score of 1494 and a Passmark single-thread score of 3283, is competent but not exceptional. In a game like Rust, which can be CPU-intensive in certain scenarios (e.g., rendering large bases or many entities), the 5700G’s 16 MB of L3 cache and 8 cores are adequate, but they are not the best available.

Comparatively, the combo’s rank implies that many other pairings with more powerful CPUs (e.g., higher-clocked or higher-cache parts) achieve better results, even with the same GPU. However, the measured FPS data shows that at 1080p and 1440p, the CPU is not a significant bottleneck, as the system achieves high framerates. The rank likely reflects the fact that at 4K, where the GPU is the limit, the CPU’s influence is minimal, but at lower resolutions, other CPUs might push framerates higher. Overall, this combo is well-balanced for 1440p gaming, but it does not stand out as a top-tier performer in the database.

CPU Role

The AMD Ryzen 7 5700G plays a supporting role in this pairing, and the data shows its influence is most pronounced at lower resolutions where the GPU is less stressed. The CPU has 8 cores and 16 threads, based on the Zen 3 architecture (Cezanne codename), with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. It is unlocked for overclocking, and its 65 W TDP is low, but its performance is modest compared to dedicated gaming CPUs. The CPU’s L3 cache is 16 MB, which is half of what some Ryzen 5000 series desktop parts offer, and this could impact performance in cache-sensitive workloads.

Benchmark results show the CPU’s multi-threaded capability is decent, with a Cinebench R23 multicore score of 12830.5 and a Geekbench multicore score of 9950. Its single-thread performance is adequate, with a Cinebench R23 single-core score of 1494 and a Passmark single-thread score of 3283. The CPU’s 3DMark 16-thread score of 6629 and max-thread score of 6627 are nearly identical, indicating that scaling beyond 8 threads is limited, which is typical for a 8-core part. The CPU’s nearest rival, the Intel Core i9-9900K, has an average score just 0.2% higher, showing they are closely matched.

In Rust, the CPU’s role is evident in the FPS deltas at 1080p. For instance, at 1080p Low, the system achieves 192 FPS, but at 1080p Medium, it drops to 150 FPS, a 42 FPS difference. This suggests that the CPU is able to sustain high framerates, but as settings increase, the GPU’s workload rises, and the CPU’s headroom allows it to keep up. However, at 4K, the CPU’s influence is minimal, as the FPS differences between presets are entirely attributable to the GPU’s limits. The data indicates that the CPU is not a bottleneck at 4K, but at 1080p, a faster CPU might be able to push framerates higher, particularly at Low settings where the GPU is less stressed. The 5700G’s integrated Radeon Vega 8 graphics are irrelevant here, as the discrete GPU handles all rendering.

The data shows a clear progression: at 1080p, the system is capable of very high framerates across all presets, with Low hitting 192 FPS and Ultra still achieving 96 FPS. At 1440p, the 60 FPS threshold is met by all presets, with Ultra at 66 FPS being the lowest. At 4K, only Low and Medium meet or exceed 60 FPS on average, with Medium’s minimum of 52 FPS indicating occasional dips. The Ultra preset at 4K is not recommended, as the average of 39 FPS is below playable standards. The Medium preset’s minimum and maximum values (e.g., 128-173 at 1080p, 88-119 at 1440p, 52-70 at 4K) show that Rust has a wide variance in frame times, consistent with its dynamic world and server-dependent performance.
