Rust

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4080 presents a stark contrast in raw capability within the context of Rust. The data indicates a system where the GPU is operating far above the CPU's weight class, with benchmark results showing a significant bottleneck at lower resolutions. This analysis examines the measured frame rates across three resolutions and four quality presets, detailing how this specific combination performs in the survival title.

Resolution Scaling

The measured FPS data reveals a classic case of a CPU-bound configuration at lower resolutions transitioning to a GPU-bound scenario at 4K. At 1080p with Low settings, the combo achieves an average of 202 FPS. Moving to 1440p Low drops this to 178 FPS, a 12% reduction, while 4K Low further decreases the average to 117 FPS, a 34% drop from the 1440p figure. This scaling pattern suggests that at lower resolutions, the Intel Core i3-12100F is the limiting component, as the RTX 4080 is not being fully utilized.

The trend becomes more pronounced when examining the High preset. At 1080p High, the system delivers 163 FPS on average. At 1440p High, this falls to 112 FPS, a 31% decrease. The jump to 4K High yields just 66 FPS, which is a 41% reduction from the 1440p result. The significant percentage drops between 1080p and 1440p indicate that the CPU's four cores are struggling to feed the GPU with enough frames, even as the resolution increases and places more load on the graphics card.

The Medium preset shows a similar pattern, with 173 FPS at 1080p, 133 FPS at 1440p, and 79 FPS at 4K. The difference between 1080p and 1440p Medium is a 23% drop, while the 4K result is 41% lower than 1440p. This data suggests that the CPU bottleneck is most severe at 1080p, where the frame rate is capped by the processor's limits rather than the GPU's rendering capacity.

At Ultra settings, the scaling is more linear. The system produces 124 FPS at 1080p, 85 FPS at 1440p, and 50 FPS at 4K. The percentage drops are 31% and 41% respectively, which closely mirrors the High preset's scaling. This indicates that the Ultra preset places enough load on the GPU to start alleviating the CPU bottleneck, though the 4K Ultra result of 50 FPS shows the RTX 4080 is still not performing to its full potential given the processor's limitations.

Settings Recommendations

Based on the measured rows, the most balanced experience appears to be the Medium preset at 1440p, which yields an average of 133 FPS with a minimum of 113 FPS and a maximum of 153 FPS. This configuration provides a smooth gameplay experience while maintaining a reasonable visual quality. The minimum frame rate of 113 FPS ensures that the game remains playable during intense moments, which is crucial for a survival title where combat and building can cause performance spikes.

For users prioritizing maximum frame rates, the Low preset at 1080p delivers 202 FPS on average. However, this comes at the cost of visual fidelity. The data shows that the High preset at 1080p offers 163 FPS, which is still well above the 144 Hz refresh rate common among gaming monitors. The difference between Low and High at 1080p is only 39 FPS, suggesting that the visual upgrade from Low to High is relatively inexpensive in terms of performance.

At 4K, the Medium preset provides 79 FPS on average, with a minimum of 67 FPS and a maximum of 90 FPS. This is the only 4K preset with recorded minimum and maximum values, and the 67 FPS minimum is close to the 60 FPS threshold for smooth gameplay. The Ultra preset at 4K drops to 50 FPS, which may be too low for competitive play but is acceptable for a more immersive visual experience.

The data suggests that the High preset at 1440p, yielding 112 FPS, is a strong alternative for users who want better visuals than Medium without sacrificing too much performance. The 21 FPS difference between High and Medium at 1440p is notable, but the High preset still maintains an average above 100 FPS, which is suitable for most gaming scenarios.

GPU Role

The NVIDIA GeForce RTX 4080 features 16 GB of GDDR6X memory on a 256-bit bus, providing a memory bandwidth of 716.8 GB/s. The GPU's base clock is 2205 MHz with a boost clock of 2505 MHz. In Rust, the memory capacity is more than sufficient for the game's assets, and the bandwidth is unlikely to be a limiting factor. The bottleneck in this configuration lies elsewhere, as evidenced by the frame rate scaling.

The RTX 4080's benchmark scores show it to be a highly capable card, with a 3DMark Steel Nomad DX12 score of 6567 and a Passmark G3D score of 34457. Its percentile ranking of 86 among all GPUs places it in the upper echelon of graphics cards. Despite this, the measured FPS in Rust at 1080p and 1440p are lower than what the GPU alone could achieve, confirming that the CPU is holding back performance.

The GPU's Ada Lovelace architecture, built on a 5 nm process, includes 9728 shading units and 76 RT cores. The FP32 performance is rated at 48.74 TFLOPS. These specifications are far beyond what Rust requires, and the data suggests that the GPU is not the limiting factor at resolutions below 4K. At 4K, the GPU begins to become more relevant, but the 50 FPS result at Ultra settings still indicates that the CPU is preventing the GPU from reaching its full potential.

The 16 GB of VRAM is ample for Rust, which is known for its large maps and numerous entities. The memory clock of 1400 MHz (22.4 Gbps effective) provides the 716.8 GB/s bandwidth. This is more than adequate for the game's texture streaming and draw calls, as evidenced by the fact that the GPU is not the bottleneck at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all presets. The Low preset averages 202 FPS, while Medium averages 173 FPS with a minimum of 147 FPS and a maximum of 199 FPS. High averages 163 FPS, and Ultra averages 124 FPS. The spread between Low and Ultra is 78 FPS, which is significant. The Medium preset's minimum of 147 FPS is particularly noteworthy, as it shows that even during demanding scenes, the frame rate stays well above the 144 Hz threshold.

Moving to 2560x1440, the frame rates decrease across the board. Low averages 178 FPS, Medium averages 133 FPS with a minimum of 113 FPS and a maximum of 153 FPS, High averages 112 FPS, and Ultra averages 85 FPS. The Medium preset at this resolution offers the best balance, with a minimum frame rate of 113 FPS ensuring smooth gameplay. The High preset's 112 FPS average is close to the Medium's minimum, indicating that the High preset is more demanding and may cause occasional dips below 100 FPS.

At 3840x2160, the system struggles to maintain high frame rates. Low averages 117 FPS, Medium averages 79 FPS with a minimum of 67 FPS and a maximum of 90 FPS, High averages 66 FPS, and Ultra averages 50 FPS. The Medium preset at 4K is the only one with a minimum above 60 FPS, making it the recommended choice for 4K gaming. The Ultra preset's 50 FPS average is below the 60 FPS threshold, which may result in noticeable stuttering.

The data also reveals that the difference between Low and Medium at each resolution is relatively consistent. At 1080p, the difference is 29 FPS; at 1440p, it is 45 FPS; and at 4K, it is 38 FPS. This suggests that the Medium preset adds a consistent workload across resolutions. The difference between Medium and High is 10 FPS at 1080p, 21 FPS at 1440p, and 13 FPS at 4K, while the difference between High and Ultra is 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K.
