Rust

The Intel Core i7-13700K paired with the NVIDIA GeForce RTX 4090 delivers exceptional performance in Rust, with measured data showing that this combination is capable of running the game far beyond the 60 FPS playable threshold at most settings. At 1920x1080, the combo achieves a staggering 253.8 FPS on Low settings, while even the most demanding Ultra preset at 4K stays playable at 56.3 FPS. This is a top-tier configuration that ranks in the 80th percentile of all 3,723 tested combos for this game, placing it among the elite systems for Rust.

Measured FPS Breakdown

The measured FPS data for this combo reveals a clear performance hierarchy across resolutions and presets. At 1920x1080, the system is overwhelmingly powerful, delivering an average of 253.8 FPS on Low settings. Moving to Medium settings drops the average to 217 FPS, while High settings produce 180.6 FPS. The Ultra preset at this resolution still achieves a very strong 135.6 FPS average, meaning every setting at 1080p is more than double the 60 FPS threshold.

At 2560x1440, the performance scaling follows a similar pattern but with slightly lower absolute numbers. The Low preset yields 221 FPS average, which is a 12.9% reduction compared to 1080p Low. Medium settings at 1440p produce 148 FPS, High settings hit 123.2 FPS, and Ultra drops to 92.9 FPS. All four presets at 1440p remain comfortably above the 60 FPS playability threshold, with the Ultra preset still providing a 54.8% margin over the minimum requirement.

The 3840x2160 results show where this combo begins to feel the strain of 4K rendering. Low settings at 4K produce 128.6 FPS, which is still highly playable. Medium settings achieve 88.9 FPS, and High settings deliver 75.8 FPS. However, the Ultra preset at 4K dips to 56.3 FPS, falling just short of the 60 FPS threshold. This is the only tested configuration where the combo fails to clear the playable bar, and it does so by a narrow 3.7 FPS margin.

The scaling between resolutions is consistent: dropping from 1080p to 1440p reduces average FPS by roughly 13-23% depending on preset, while moving from 1440p to 4K incurs a larger 38-49% penalty. The most dramatic drop occurs at 4K Ultra, where performance falls 58.5% below the 1080p Ultra result. This pattern confirms that the RTX 4090 is the primary driver of resolution scaling, with the CPU maintaining sufficient headroom at all tested settings.

CPU and GPU Roles

The data indicates that the GPU becomes the dominant performance factor as resolution increases, while the CPU holds a more significant role at lower resolutions. At 1920x1080, the difference between Low and Ultra presets is 118.2 FPS, suggesting that the RTX 4090 is being pushed harder by higher graphics settings, but the i7-13700K is still able to feed it effectively. The CPU's 16 cores and 24 threads, combined with a boost clock of 5.40 GHz, provide ample processing power for Rust's simulation and physics workloads.

At 2560x1440, the performance gap between Low and Ultra narrows to 128.1 FPS, but the relative scaling shows the GPU taking on more work. The transition from 1080p to 1440p at the same preset results in a 13-23% FPS reduction, which is relatively modest and indicates that the system is not yet GPU-bound at these settings. The CPU continues to keep pace, as evidenced by the 1440p Low result of 221 FPS, which is only 12.9% below the 1080p Low figure.

The 3840x2160 results reveal a clear GPU bottleneck at the highest resolution. The 4K Ultra preset drops to 56.3 FPS, which is 58.5% below the 1080p Ultra score. This steep decline suggests that the RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are being saturated by 4K Ultra settings, while the CPU has more than enough headroom. The fact that 4K Low still achieves 128.6 FPS demonstrates that the CPU can handle the game's logic at high frame rates, but the GPU's pixel throughput becomes the limiting factor at higher resolutions.

Preset scaling further clarifies the role split. At 1080p, moving from Low to Ultra costs 118.2 FPS, while at 4K the same preset change costs 72.3 FPS. This inverted relationship indicates that at lower resolutions, the GPU has spare capacity and the CPU can push frame rates higher, whereas at 4K, the GPU is already near its limit and preset changes have less absolute impact. The i7-13700K's strong single-thread performance, evidenced by its 3DMark single-thread score of 1136, ensures it is rarely the bottleneck in this configuration.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the AMD Ryzen 9 5900 offers nearly identical performance with an average score of 46,971, just 0.2% higher than the i7-13700K. This means systems using the Ryzen 9 5900 would produce very similar frame rates in Rust, with differences likely imperceptible in real gameplay. The AMD Ryzen AI 9 HX PRO 375 is also closely matched at 47,022, 0.3% higher, making it another viable alternative for similar CPU-bound scenarios.

The AMD Ryzen 9 7845HX and Intel Xeon w3-2535 both score approximately 46,654 and 46,653 respectively, placing them 0.5% behind the i7-13700K. These processors would deliver nearly identical performance in Rust, though the Xeon's server-oriented design may not offer the same gaming features as the consumer-focused i7. For gaming, the Ryzen 9 5900 or the Ryzen 9 7845HX would be the most direct replacements.

On the GPU side, the RTX 4090's nearest rival is the Intel Arc Pro A60, which scores 60,326, essentially identical at 0% delta. This suggests the Arc Pro A60 could deliver comparable frame rates in Rust, though the RTX 4090's 24 GB VRAM versus the Arc's unspecified memory capacity may affect high-resolution textures. The AMD Radeon Pro W6600M scores 61,896, which is 2.5% higher, indicating it could provide a slight performance edge in GPU-bound scenarios.

The AMD Radeon Pro Vega 48 scores 60,140, 0.3% lower than the RTX 4090, while the AMD Radeon PRO V710 scores 58,657, 2.9% lower. These GPUs would produce slightly lower frame rates, but still likely maintain playability at most settings. However, none of these rivals match the RTX 4090's combination of raw performance and 24 GB of GDDR6X memory, which is particularly relevant for Rust's large open-world environments at 4K.

The Verdict

This PC configuration can run Rust with excellent performance across the vast majority of tested settings. At 1920x1080, every preset clears the 60 FPS threshold with substantial margin, with the Ultra preset delivering 135.6 FPS, more than double the playable requirement. The 2560x1440 resolution is fully playable at all settings, with Ultra achieving 92.9 FPS and even the most demanding preset maintaining a 54.8% buffer above the threshold.

At 3840x2160, the system is playable at High, Low, and Medium settings, with High being the best visual option at 75.8 FPS. The Ultra preset at 4K falls short at 56.3 FPS, which is 3.7 FPS below the 60 FPS threshold. This is the only configuration where the combo fails to meet the playability standard, and it does so by a narrow margin that could be addressed by minor tweaks such as reducing shadow quality or draw distance.

For most users, the recommended setup is 2560x1440 Ultra, which provides the best balance of visual fidelity and performance at 92.9 FPS. At 1080p, all settings are viable, with even the most demanding preset delivering smooth gameplay. The 4K experience is strong but not flawless, requiring a step down from Ultra to High for consistent 60+ FPS performance.
