Rust

The data for Rust, captured with an Intel Core i5-14400F and an NVIDIA GeForce RTX 5080, reveals a pairing that shifts its bottleneck character dramatically depending on the resolution and preset selected. This is not a static relationship; the measured frames per second (FPS) show the CPU holding its own at lower resolutions while the GPU becomes the definitive limiting factor as pixel counts climb.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 paints a clear picture of where the performance ceiling lies. At the High preset, the average frame rate drops from 170.5 FPS at 1080p to 118.2 FPS at 1440p, a significant 30.7% reduction. Pushing further to 4K yields 71.3 FPS, which is 58.2% lower than the 1080p result. This steep decline is the classic signature of a GPU-bound scenario at higher resolutions; the RTX 5080's rendering workload scales directly with pixel count, while the CPU's job of preparing frames remains relatively constant.

The scaling pattern shifts when examining the Low preset. Here, the drop from 1080p (217.3 FPS) to 1440p (191.6 FPS) is a more modest 11.8% decrease. The move to 4K (123.1 FPS) represents a 43.4% reduction from 1080p. The comparatively smaller penalty at 1440p suggests that at this lower graphical load, the system is beginning to encounter a CPU limitation. The i5-14400F, with its 10 cores and 16 threads, is likely the component preventing the frame rate from scaling higher at 1080p and 1440p Low, as the GPU has ample headroom to render frames faster than the processor can feed it.

The Ultra preset shows the most dramatic scaling loss. At 1080p, the system manages 132.4 FPS, but this plummets to 88.9 FPS at 1440p and further down to 56.3 FPS at 4K. The 4K result is 57.5% lower than the 1080p figure. This aggressive drop highlights the immense strain that the Ultra preset places on the GPU, making it the unequivocal bottleneck at all resolutions tested. The data implies that users targeting high refresh rates at 4K with this preset will find the RTX 5080's capabilities stretched to their limit.

How This Combo Ranks

Within the extensive database of tested combinations, this specific pairing of CPU and GPU achieves a combo rank of 68 out of 1717 total combos for Rust. This places it in the top 4% of all tested systems, indicating a very high-performing configuration for this particular game. The percentile data for the individual components supports this: the CPU sits in the 88th percentile among all processors, while the GPU is in the 89th percentile among all graphics cards.

The high combo rank suggests that the i5-14400F and RTX 5080 are well-matched for Rust, with neither component being a severe drag on the other's potential. The CPU's performance is closely aligned with rivals like the Intel Core i7-12800H, which has an average score just 0% different. Similarly, the GPU's average benchmark score is within a 1.6% delta of the Intel Arc A570M and a 2.5% delta from the Intel Arc A580. This proximity in synthetic benchmarks, however, does not fully translate to in-game performance, where the RTX 5080's architecture and driver optimizations for a title like Rust can yield different results.

The rank implies that while the hardware is powerful, there are still 67 other combinations that deliver higher average frame rates in this game. These could involve more potent CPUs with higher boost clocks or GPUs with even greater raw throughput. The data does not specify what those combos are, but it positions this setup as a strong, top-tier performer rather than an absolute leader.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. Its base clock is 2.50 GHz, which can boost up to 4.70 GHz. For a game like Rust, which is known for its complex simulation and physics, the thread count is often more critical than raw clock speed. The 16 threads provide ample parallelism to handle the game's server-side and client-side simulation tasks, helping to maintain consistent frame pacing.

In the measured results, the CPU's influence is most apparent when the GPU is not the primary constraint. At 1080p with Low settings, the system achieves 217.3 FPS. This high number indicates the CPU is capable of feeding the GPU enough data to reach frame rates well above 200. However, the fact that the 1440p Low result (191.6 FPS) is not proportionally lower suggests that the CPU's frame generation limit may be in the 190-220 FPS range for this title. The CPU's performance in synthetic benchmarks, such as a Cinebench R23 multi-core score of 21914 and a single-core score of 3093, supports its capability in both multi-threaded and single-threaded workloads.

The i5-14400F's 20 MB of shared L3 cache is another relevant factor. Rust's large, persistent world requires frequent access to game data, and a larger cache can reduce latency when fetching that information. The processor's 65W TDP suggests it operates within a modest power envelope, which can be beneficial for system thermals during extended play sessions. The data shows that the CPU is not a weak link, as it allows for very high frame rates in less demanding scenarios, but it does appear to impose a ceiling around 217 FPS in this specific test configuration.

Measured FPS Breakdown

The complete set of measured results provides a granular view of performance across all settings and resolutions. At 1920x1080, the frame rates are consistently high, ranging from a low of 132.4 FPS on Ultra to a high of 217.3 FPS on Low. The Medium preset delivers 187.2 FPS, while High achieves 170.5 FPS. This shows a clear linear progression where lower graphical fidelity directly translates to higher frame rates, with a 64% difference between the Ultra and Low presets at this resolution.

Moving to 2560x1440, the performance hierarchy remains but the absolute numbers drop. Low settings produce 191.6 FPS, which is still incredibly smooth. High settings yield 118.2 FPS, and Medium lands at 141 FPS. The Ultra preset drops to 88.9 FPS, which is the first time any preset falls below the 100 FPS mark in the data. The scaling from 1080p to 1440p for the Low preset is a 11.8% decrease, but for the Ultra preset, it is a 32.9% decrease, showing the GPU's growing burden.

At 3840x2160, the GPU is clearly the dominant factor. Low settings are the only preset to break the 120 FPS barrier, hitting 123.1 FPS. Medium settings manage 81.8 FPS, High settles at 71.3 FPS, and Ultra drops to 56.3 FPS. The spread between Low and Ultra at 4K is 54.3%, indicating that the RTX 5080's 16 GB of VRAM and 960.0 GB/s of memory bandwidth are being heavily taxed by the higher fidelity settings, with the Ultra preset's demands proving particularly punishing for high-refresh-rate 4K gaming.

GPU Role

The NVIDIA GeForce RTX 5080 is a formidable GPU built on the Blackwell 2.0 architecture with a 5 nm process node. It features 10752 shading units and 112 ROPs, with a boost clock of 2617 MHz. Its 16 GB of GDDR7 memory on a 256-bit bus provides a substantial 960.0 GB/s of bandwidth. These specifications make it a top-tier card, evidenced by its 89th percentile ranking and an average benchmark score of 59188.

In Rust, the GPU's role is most pronounced at higher resolutions and presets. The performance drop from the Medium to Ultra preset at 4K is particularly telling: 81.8 FPS down to 56.3 FPS, a 31.2% reduction. This suggests that the Ultra preset introduces graphical effects, such as increased draw distances, richer shadows, and more complex textures, that significantly increase the GPU's workload. The RTX 5080's 84 RT cores and 336 tensor cores may also be engaged for specific rendering features within the game, though the data does not specify which effects are enabled.

The GPU's memory capacity appears sufficient, as the card's 16 GB frame buffer is ample for Rust's texture-heavy environments at all tested settings. The 960.0 GB/s bandwidth ensures that texture streaming and data transfer are not bottlenecks at 4K. The card's synthetic benchmark scores, such as a 3DMark Steel Nomad DX12 score of 8637 and a Passmark G3D score of 36565, align with its high in-game performance at 1440p, but the 4K Ultra results show that even this powerful GPU has limits when pushed to maximum fidelity.

Settings Recommendations

The measured data provides a clear directive for optimizing the experience with this hardware. For users with a 1920x1080 display, the High preset is an excellent choice, delivering 170.5 FPS while likely providing a visually richer experience than the Medium preset's 187.2 FPS. The jump to Ultra at 132.4 FPS is still very playable but comes with a 22.3% performance penalty compared to High, which may not be worth the visual gain.

At 2560x1440, the High preset is the sweet spot, offering 118.2 FPS. This balances visual fidelity with a frame rate that is well above the 100 FPS mark for smooth gameplay. The Medium preset at 141 FPS is an option for those prioritizing refresh rate over absolute visual quality, but High provides a better balance. The Ultra preset at 88.9 FPS is playable but starts to approach the lower limits of high-refresh-rate gaming.

For 4K gaming at 3840x2160, the situation is more complex. The Low preset is the only one that consistently delivers high frame rates, hitting 123.1 FPS. For a competitive or high-refresh-rate experience, this is the recommended preset. The Medium preset at 81.8 FPS is a viable alternative for a more visually rich experience, but users must accept a 33.5% reduction in frame rate compared to Low. The High preset at 71.3 FPS is playable, but the Ultra preset's 56.3 FPS is below the 60 FPS target and should be avoided for a consistently smooth experience. The data suggests that for 4K, the High and Ultra presets tax the GPU too heavily for this combination to maintain high refresh rates.
