Rust

The AMD Ryzen 7 9700F and NVIDIA GeForce RTX 5090 pairing produces a striking FPS curve in Rust, one that reveals a system with immense headroom and a clear dependence on resolution and settings. The benchmark data shows a combination that can push well past 200 FPS at 1080p but settles into a more modest range at 4K, indicating a shift in the bottleneck as pixel count rises.

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

The data shows a dramatic FPS drop as resolution increases, but the pattern is not uniform across all settings presets. At Low settings, the average FPS falls from 276 at 1920x1080 to 224 at 2560x1440, a reduction of 52 FPS, and then to 132 at 3840x2160, a further drop of 92 FPS. This steep decline at 4K, even on Low, suggests the GPU is being increasingly tasked with filling those extra pixels, moving away from a CPU-bound scenario. The 1080p Low result of 276 FPS is the highest figure in the entire dataset, indicating that at this resolution, the Ryzen 7 9700F's 8 cores and 16 threads are more than capable of feeding frames to the RTX 5090, and the GPU is not yet the limiting factor.

At High settings, the scaling is similar but with lower absolute values. The average FPS goes from 185 at 1080p to 127 at 1440p, a 58 FPS drop, and then to 75 at 4K, a 52 FPS drop. The transition from 1080p to 1440p removes 31% of the performance, while the transition from 1440p to 4K removes 41%. This indicates that the GPU's workload is scaling super-linearly with resolution, which is typical for a game like Rust that has complex draw calls and shadow rendering. The fact that the delta between 1440p and 4K is larger than the delta between 1080p and 1440p suggests that at 4K, the RTX 5090 is finally hitting a wall where its raw compute and memory bandwidth are being saturated.

The Medium preset shows the most interesting data, as it is the only preset with min and max FPS values recorded. At 1080p Medium, the average is 219 FPS with a min of 186 and a max of 251, showing a 65 FPS spread. At 1440p Medium, the average is 150 FPS with a min of 128 and a max of 173, a 45 FPS spread. At 4K Medium, the average is 89 FPS with a min of 76 and a max of 102, a 26 FPS spread. The shrinking variance at higher resolutions is a clear sign of a GPU bottleneck. When the GPU is the limiting factor, frame times become more consistent because the CPU has ample time to prepare frames, whereas at 1080p, the CPU is racing to keep up, leading to larger frame time spikes and a wider range of FPS.

The Ultra preset tells a similar story. The average FPS drops from 140 at 1080p to 97 at 1440p, and then to 57 at 4K. The 4K Ultra result of 57 FPS is the lowest in the entire dataset, and it is telling that this is the only configuration that dips below the 60 FPS threshold. The drop from 1440p to 4K at Ultra is 40 FPS, which is a 41% reduction, nearly identical to the High preset's reduction. This consistency across High and Ultra presets suggests that the GPU's memory subsystem and shading units are the primary constraints at 4K, rather than a specific setting like shadows or textures.

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

The NVIDIA GeForce RTX 5090 is a massive piece of silicon, built on the Blackwell 2.0 architecture with a 5 nm process node. It features 32 GB of GDDR7 memory on a 512-bit bus, yielding a bandwidth of 1.79 TB/s. The benchmark results show this hardware is more than sufficient for Rust, even at 4K Ultra. The fact that the GPU can maintain an average of 57 FPS at 4K Ultra, while the CPU is not the bottleneck, indicates that the RTX 5090's 21,760 shading units are being pushed hard but are still delivering playable results.

The GPU's boost clock of 2407 MHz, up from a base of 2017 MHz, is a key factor in its performance. The data shows that at 1080p, the GPU is not the limiting factor, as the FPS is likely capped by the CPU's ability to issue draw calls. However, at 4K, the GPU's clock speed and its ability to sustain that boost clock under load become critical. The 104.8 TFLOPS of FP32 compute power is what allows the card to process the complex pixel shaders and lighting calculations required by Rust's dynamic world at 4K. The 176 ROPs are also crucial for the final pixel output stage, and their performance is directly reflected in the 4K results.

The 32 GB of VRAM is another interesting aspect. Rust is known for its large memory footprint, especially with high-resolution textures and long play sessions. While the data does not include VRAM usage, the fact that the card has 32 GB means it is unlikely to ever run out of memory, which could otherwise cause stuttering or texture pop-in. The 1.79 TB/s bandwidth is also a major advantage, as it allows the GPU to quickly stream textures and geometry data from VRAM, which is essential for maintaining smooth frame rates in a game where the environment is constantly being modified by players. In contrast, a card with less bandwidth might see FPS drops when traversing dense areas or when many players are on screen.

This places it in the top 1.2% of all configurations, which is an exceptional result. The data implies that this pairing is near the apex of what is currently possible for this game, with only 34 other combos outperforming it. Given that the RTX 5090 is a top-tier GPU and the Ryzen 7 9700F is a high-end desktop processor, this high ranking is expected, but the specific rank relative to other top-tier combos is informative.

The CPU's average benchmark score of 69,996 places it in the 94th percentile of all CPUs, and its nearest rivals include the AMD Ryzen 9 7940HX, which is 0.2% faster, and the Intel Core i7-14700KF, which is 0.2% slower. The GPU's average benchmark score of 79,842 places it in the 92nd percentile of all GPUs, with its nearest rival being the NVIDIA Tesla P100 PCIe 16 GB, which is 0.3% faster. These benchmark scores suggest that neither component is a weak link in the chain, and their combination results in a top-35 finish in Rust.

The fact that 34 other combos are faster could be due to slight variations in CPU or GPU clock speeds due to silicon lottery, or it could be that those combos feature a CPU with higher single-thread performance, which is critical for Rust's physics and entity update loops. The Ryzen 7 9700F has a boost clock of 5.50 GHz, but other CPUs in the 9000 series might have higher sustained all-core clocks. Regardless, a rank of 35 out of 2953 reflects the balance of this pairing.

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

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate. For players with a 1080p 144Hz monitor, the Medium preset is the sweet spot. It averages 219 FPS, which is well above the 144 Hz refresh rate, and the minimum of 186 FPS ensures that there will be minimal dips below the refresh rate, providing a consistently smooth experience. While the Low preset averages 276 FPS, the visual quality hit is substantial for a marginal gain in frame rate that is likely beyond the monitor's capabilities.

At 1440p, the High preset is the recommended choice. It averages 127 FPS, which is just below the 144 Hz mark but still very playable. The Medium preset averages 150 FPS, but the jump to High provides a significant visual improvement for a 23 FPS cost. For those with a 1440p 120Hz monitor, the High preset is ideal, as the average of 127 FPS is above the refresh rate, and the extra fidelity will be appreciated in a game like Rust where environmental details matter.

At 4K, the situation is more complex. The High preset averages 75 FPS, which is a good target for a 60Hz or 75Hz monitor. The Medium preset averages 89 FPS, which is also viable, but the visual difference between Medium and High is often noticeable in terms of texture filtering and shadow quality. The Ultra preset at 57 FPS is not recommended unless the player has a VRR display and can tolerate the lower frame rate for maximum fidelity. The Low preset at 132 FPS is a viable option for competitive play, but the visual downgrade is severe. The data suggests that High is the best compromise for 4K, offering a solid frame rate without sacrificing too much visual quality.

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

The AMD Ryzen 7 9700F is a Zen 5 architecture processor with 8 cores and 16 threads, running at a base clock of 3.80 GHz and a boost clock of 5.50 GHz. Its benchmark scores are impressive, with a multithread score of 36,470 and a single-thread score of 4,691. These scores are crucial for Rust, which is a game that is heavily reliant on single-thread performance for its main game loop and physics simulation, but also benefits from multi-threading for chunk generation and AI updates.

The data shows that at 1080p Low, the CPU is the limiting factor. The FPS of 276 is likely near the maximum that the CPU can produce, as the GPU is capable of much more. This is supported by the fact that the Ryzen 7 9700F's nearest rivals in terms of average benchmark score include the Intel Core i7-14700KF and the Intel Core i7-14700K, both of which are known for strong single-thread performance. The 5.50 GHz boost clock is a key differentiator, allowing the CPU to quickly process the game's logic.

The 32 MB of shared L3 cache is also important for Rust. The game has a large, persistent world that is constantly being updated, and a larger cache can help reduce memory latency, which is critical for maintaining stable frame times. The CPU's memory bandwidth of 89.6 GB/s with DDR5 support is another factor, as Rust's asset streaming can benefit from faster memory access. The high single-thread score of 4,691 in the Passmark benchmark indicates that the CPU can handle the game's primary thread efficiently, which is why the FPS at 1080p is so high. The 65W TDP suggests that the CPU is efficient, but the data shows that its performance is not limited by power constraints, as it maintains high clock speeds under load.
