Rust

Resolution Scaling

The measured FPS data across the three resolutions reveals a classic GPU-bound scaling pattern for this combination of the Intel Core i5-12600KF and AMD Radeon RX 7900 XTX in Rust. Moving from 1920x1080 to 2560x1440 on the High preset, average frame rate drops from 150.7 FPS to 103.1 FPS, a reduction of approximately 31.6%. The subsequent move to 3840x2160 on High brings the average down to 61.2 FPS, which is a further 40.6% reduction from the 1440p figure. This steep, compounding decline indicates that the rendering workload is scaling heavily with pixel count, which is the signature of a system where the GPU is the primary performance limiter at these higher resolutions.

The Low preset tells a similar story but with a different starting point. At 1080p Low, the combo achieves 230.8 FPS, which drops to 177.6 FPS at 1440p and then to 106.3 FPS at 4K. The absolute FPS losses are larger on the Low preset (53.2 FPS from 1080p to 1440p, and 71.3 FPS from 1440p to 4K) compared to the High preset (47.6 FPS and 41.9 FPS respectively). This suggests that even when graphical settings are reduced to lower the per-pixel cost, the sheer number of pixels at 4K still exerts a massive toll on the GPU, pushing the frame rate down by more than half from the 1080p result.

The Ultra preset demonstrates the most dramatic scaling. It starts at 112.4 FPS at 1080p, falls to 75.3 FPS at 1440p, and plummets to 44.1 FPS at 4K. The 4K Ultra result is only about 39% of the 1080p Ultra performance. This indicates that the Ultra preset introduces effects that are particularly punishing at high resolutions, and the data shows the RX 7900 XTX is being pushed to its limits. The transition from 1440p to 4K on Ultra results in a 31.2 FPS loss, which is a 41.4% decrease, highlighting that the GPU's compute and memory bandwidth are being saturated by the combination of high settings and 4K resolution.

The data suggests that at 1080p, the CPU has more headroom to feed the GPU, as evidenced by the 230.8 FPS Low result. However, the scaling pattern across all presets points to the GPU becoming the dominant constraint as resolution increases. The gap between Low and Ultra settings widens as resolution climbs, which is typical of a GPU-bound scenario. At 1080p, the difference between Low and Ultra is 118.4 FPS; at 4K, this difference compresses to 62.2 FPS. This compression indicates that at 4K, the GPU is so saturated that even reducing settings cannot fully recover frame rate, as the raw pixel throughput becomes the bottleneck.

GPU Role

The AMD Radeon RX 7900 XTX, with its 24 GB of GDDR6 memory on a 384-bit bus, provides a memory bandwidth of 960.0 GB/s. This is a critical specification for Rust, a game known for its large, persistent world and frequent asset streaming. The benchmark results show that at 4K Ultra, the combo manages 44.1 FPS, which is playable but not smooth. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz are relatively high, and the data indicates that the card is working hard to maintain these frame rates, especially given the 61.39 TFLOPS FP32 compute capacity is being fully utilized at the higher resolution settings.

The VRAM capacity appears to be a non-issue in this benchmark, as even the most demanding 4K Ultra configuration does not show signs of texture thrashing or sudden FPS drops that would indicate memory capacity limits being hit. The 24 GB buffer is more than sufficient for Rust's asset demands at these tested settings. The performance deltas between settings are more attributable to the GPU's shading and rasterization workload than to memory constraints. For instance, the jump from 4K Medium (73.4 FPS) to 4K High (61.2 FPS) is a 16.6% reduction, which aligns with increased shader complexity rather than memory allocation issues.

The GPU's role as the primary limiter is further confirmed by the fact that the CPU, with its 10 cores and 16 threads, is a strong performer in its own right. The i5-12600KF has a boost clock of 4.90 GHz and a max-thread benchmark score of 7952 in 3dmark, which places it in the 84th percentile of all CPUs. Yet, the FPS scaling pattern in this game follows the GPU's resolution curve almost exactly. The RX 7900 XTX, being in the 85th percentile of all GPUs, is the component that needs to be adjusted via settings to achieve higher frame rates. The 4K High result of 61.2 FPS is close to the 60 FPS target, but the Ultra preset at 44.1 FPS shows that maxing out settings is not viable at this resolution.

How This Combo Ranks

Within the benchmark database, this specific combination of Intel Core i5-12600KF and AMD Radeon RX 7900 XTX achieves a combo rank of 194 out of 1717 tested combinations for Rust. This places it in the top 11.3% of all combos, which is a strong showing for a pairing of a mid-range 12th-gen CPU with a high-end RDNA 3 GPU. The CPU's nearest rival, the Intel Core i9-10900K, has an average benchmark score that is essentially identical, with a deltaPct of 0. The i5-12600KF also sits within 0.1% of its direct sibling, the i5-12600K, indicating that the performance difference between these CPUs is negligible in the broader context of this GPU's capabilities.

The GPU's nearest rivals provide context for its raw compute power. The NVIDIA GeForce RTX 4070 Ti has an average score that is 2% higher than the RX 7900 XTX, while the AMD Radeon Pro 580 is 0.4% lower. The RTX 4090 Mobile is 0.8% higher, but that is a mobile part with different thermal characteristics. The rank of 194 out of 1717 combos suggests that while this GPU is powerful, there are many combinations above it, likely featuring newer CPUs with higher IPC or more cores, or GPUs with even higher raw throughput. However, for the purposes of Rust, the data shows that this combo is far above average, outperforming the vast majority of tested systems.

The percentile rankings of the individual components align with the combo's overall standing. The CPU's 84th percentile and the GPU's 85th percentile suggest a balanced pairing. The combo rank being slightly lower than either individual percentile (top 11.3% vs. top 15-16%) indicates that there is some minor bottlenecking, likely at 1080p where the CPU may not be able to fully saturate the GPU's potential, or at 4K where the GPU simply runs out of steam. The deltaPct values from the nearest rivals show that the CPU is trading blows with older i9 parts and newer mobile chips, but the overall combo ranking is what matters for in-game performance, and it is solidly in the upper echelon.

Settings Recommendations

Based on the measured FPS rows, the optimal balance of visual fidelity and frame rate depends heavily on the target resolution. For 4K displays, the Ultra preset is not recommended, as the 44.1 FPS average falls below the generally accepted smoothness threshold. The High preset at 61.2 FPS is the highest quality option that stays above 60 FPS, but it is a marginal result. The Medium preset at 73.4 FPS provides a more comfortable margin above 60 FPS while still offering a significant visual upgrade over Low. For players prioritizing frame rate above all else at 4K, the Low preset at 106.3 FPS is exceptionally smooth, but it sacrifices most of the game's visual richness.

At 2560x1440, the data supports using the High preset, which delivers 103.1 FPS. This is well above the 60 FPS target and offers a good balance of quality and performance. The Medium preset at 120.4 FPS is also a strong choice for those who want extra headroom for competitive play, while the Ultra preset at 75.3 FPS is viable for those who want maximum visual quality and can tolerate slightly lower frame rates. The Low preset at 177.6 FPS is essentially a competitive mode, prioritizing maximum responsiveness over visuals.

For 1920x1080, the High preset at 150.7 FPS is the recommended default, as it provides a high frame rate that exceeds most high-refresh-rate monitors' capabilities. The Medium preset at 173.5 FPS offers a slight boost for esports-style play. The Ultra preset at 112.4 FPS is also perfectly playable and provides the full visual experience without dropping below the 100 FPS mark. The Low preset at 230.8 FPS is the highest achievable frame rate in this dataset and is ideal for users with 240Hz displays. The data shows that 1080p is the resolution where this combo has the most headroom, allowing users to choose between quality and speed without compromise.

Measured FPS Breakdown

At 1920x1080, the benchmark results show a clear progression across settings. The Low preset achieves an average of 230.8 FPS, which is the highest measured frame rate in the entire dataset. The Medium preset delivers 173.5 FPS, a 24.8% reduction from Low. High follows at 150.7 FPS, and Ultra is the slowest at 112.4 FPS. The delta between Low and Ultra at 1080p is 118.4 FPS, indicating that the GPU has ample performance headroom at this resolution to absorb the increased workload of higher settings.

At 2560x1440, the frame rates scale down predictably. Low is measured at 177.6 FPS, which is still very high. Medium drops to 120.4 FPS, and High comes in at 103.1 FPS. Ultra falls to 75.3 FPS. The difference between Low and Ultra at this resolution is 102.3 FPS, slightly less than at 1080p, showing the onset of GPU saturation. The gap between Medium and High at 1440p is 17.3 FPS, which is a 14.4% penalty for the visual upgrade.

At 3840x2160, the GPU is clearly the limiting factor. Low yields 106.3 FPS, which is respectable. Medium drops to 73.4 FPS, and High falls to 61.2 FPS. Ultra is the only setting that dips below 60 FPS, at 44.1 FPS. The scaling from Low to Ultra at 4K is a 58.5% reduction in performance, highlighting the massive cost of enabling the highest settings at this pixel count. The transition from 1440p High (103.1 FPS) to 4K High (61.2 FPS) represents a 40.6% performance loss, which is the steepest single-resolution penalty observed in the High preset across the dataset.
