Rust

Rust, a survival title that has been live since early 2018, remains a demanding benchmark for modern hardware. This analysis examines the measured performance of the Intel Core i5-14600K paired with the NVIDIA GeForce RTX 4070 SUPER across three resolutions and four quality presets. The data shows a configuration that scales predictably with resolution, but the relationship between CPU and GPU load reveals specific bottlenecks that dictate the optimal settings for this pairing.

Resolution Scaling

The performance delta between 1080p and 4K is substantial, indicating a system that transitions from a CPU-bound state to a GPU-bound state as pixel count increases. At the Ultra preset, the average frame rate drops from 106.5 FPS at 1920x1080 to 75.9 FPS at 2560x1440, a reduction of approximately 29%. Moving to 4K at 3840x2160, the Ultra preset further falls to 43.5 FPS, which is a 59% decrease from the 1080p result. This steep decline suggests that at 4K Ultra, the GeForce RTX 4070 SUPER is the primary limiting component, struggling to maintain fluid frame rates under maximum load.

The scaling pattern is even more pronounced at the Low preset. The RTX 4070 SUPER achieves 251.7 FPS at 1080p Low, but this figure drops to 169.7 FPS at 1440p and then to 100.6 FPS at 4K. The percentage drop from 1080p to 4K at Low settings is roughly 60%, which is nearly identical to the Ultra preset's scaling. This consistency indicates that while the absolute frame rates are much higher at Low, the GPU's workload increases proportionally with resolution regardless of the quality settings. However, the fact that Low settings at 1080p produce over 250 FPS strongly implies that the CPU is the bottleneck at that resolution, as the GPU has ample headroom to render frames far beyond typical display refresh rates.

The Medium preset offers a middle ground, with frame rates of 167.9 FPS at 1080p, 116.1 FPS at 1440p, and 67.7 FPS at 4K. The High preset tracks similarly, delivering 140.2 FPS, 95.9 FPS, and 57.6 FPS respectively. Notably, the gap between Medium and High at 4K is only about 15%, while at 1080p the gap is nearly 20%. This suggests that as resolution increases, the incremental cost of moving from Medium to High diminishes, as the GPU becomes the limiting factor and the additional shading work is less impactful relative to the total pixel load.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on the Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. In this game, the CPU's role is most evident at lower resolutions and lower quality presets. The data shows that at 1080p Low, the system produces 251.7 FPS, which is an exceptional figure that exceeds the refresh rate of most high-end monitors. This high frame rate indicates that the i5-14600K's single-core performance, evidenced by a Cinebench R23 single-core score of 4642, is sufficient to feed the GPU quickly enough to avoid a significant bottleneck.

However, the CPU's influence wanes as resolution increases. At 4K Low, the frame rate is 100.6 FPS, which is 60% lower than at 1080p Low. This dramatic drop is not due to the CPU suddenly becoming slower, but rather because the GPU's rendering workload at 4K becomes the dominant factor. The CPU is still capable of issuing draw calls and processing game logic at a high rate, but the GPU simply cannot keep up with the pixel fill rate required at 3840x2160. The benchmark results indicate that the i5-14600K's multi-core performance, with a Cinebench R23 multi-core score of 32881, is not a limiting factor even at the highest settings, as the frame rate differences between presets at the same resolution are driven by GPU load.

The processor's percentile rank of 93 versus all CPUs, with an average benchmark score of 49166, places it in the top tier for gaming. Its nearest rival, the AMD Ryzen 9 5950X, scores 49062, a negligible 0.2% difference, while the Intel Core i5-14600KF scores 49367, a -0.4% delta. This suggests that the 14600K is well-matched to the RTX 4070 SUPER, providing enough computational headroom to ensure that the GPU is the bottleneck in most scenarios above 1080p.

Settings Recommendations

Based on the measured FPS rows, the optimal experience depends heavily on the target resolution and desired frame rate. At 1920x1080, the High preset delivers 140.2 FPS, which is smooth for competitive play, but the Ultra preset drops to 106.5 FPS. For players with a 144Hz monitor, the High preset is the sweet spot, as it provides a 32% higher frame rate than Ultra while likely offering a visually similar experience in a game like Rust. The Low preset at 1080p produces 251.7 FPS, but this is excessive for most displays and sacrifices visual fidelity for a marginal practical benefit.

At 2560x1440, the Medium preset at 116.1 FPS offers the best balance for high-refresh-rate gaming, as it exceeds the 100 FPS threshold that many consider the baseline for smooth gameplay. The High preset at 95.9 FPS is also acceptable, but the drop below 100 FPS may be noticeable to sensitive users. The Ultra preset at 75.9 FPS is playable but not ideal for fast-paced action, and it represents a 35% performance penalty over Medium. For 1440p, the data suggests that Medium or High are the recommended presets, as they maintain frame rates above 95 FPS while still providing decent visual quality.

At 3840x2160, the situation is more constrained. The Low preset at 100.6 FPS is the only option that clears the 100 FPS bar, but it requires significant visual compromises. The Medium preset at 67.7 FPS and High preset at 57.6 FPS are both playable but may feel sluggish in combat scenarios, while the Ultra preset at 43.5 FPS is below the threshold for a smooth experience. For 4K, the Low preset is the only recommendation for competitive play, while Medium is acceptable for casual exploration. The data clearly indicates that 4K Ultra is not a viable option for this configuration in Rust.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER, built on the Ada Lovelace architecture with a 5 nm process, is the dominant force in this configuration's performance at higher resolutions. Its 12 GB of GDDR6X memory on a 192-bit bus provides a bandwidth of 504.2 GB/s, which is sufficient for Rust's texture and asset streaming demands. The GPU's base clock of 1980 MHz and boost clock of 2475 MHz allow it to scale its performance dynamically, but the measured data shows that even with these clocks, 4K Ultra is beyond its capabilities.

The GPU's compute specifications include 7168 shading units, 224 texture mapping units, and 80 ROPs, which collectively contribute to its 35.48 TFLOPS of FP32 performance. This raw compute power translates to a Passmark G3D score of 29995, placing it in the 84th percentile of all GPUs. Its nearest rival, the NVIDIA RTX A6000, scores 42653, a -0.2% delta, while the AMD Radeon RX 7650 GRE scores 42723, a -0.3% delta. This indicates that the RTX 4070 SUPER is positioned competitively in the upper mid-range tier.

In Rust specifically, the GPU's role becomes critical at 1440p and 4K. At 1080p, the CPU can feed frames fast enough that the GPU is not fully utilized, as evidenced by the 251.7 FPS at Low settings. However, at 4K, the GPU must process four times as many pixels as 1080p, and the frame rate drops accordingly. The difference between Low and Ultra at 4K is 57.1 FPS (100.6 vs 43.5), showing that the GPU's shading units and memory bandwidth are heavily taxed by the higher quality presets. The 12 GB VRAM is adequate for this game, as Rust does not appear to exceed this capacity based on the performance data, but the GPU's overall throughput is the limiting factor at 4K Ultra.
