Rust

The Intel Core i5-10400F paired with the AMD Radeon RX 6700 XT delivers a highly capable 1080p and 1440p experience in Rust, with the data showing a clear progression from unplayable 4K Ultra to smooth high-refresh 1080p Low. The combination ranks 965th out of 1,717 tested combos, placing it in the upper-middle tier for this title. The measured FPS results reveal that the GPU is the primary driver at higher resolutions, while the CPU’s six cores and twelve threads provide sufficient headroom for the game’s simulation-heavy load at lower settings.

FAQ

Q: What is the best resolution for this combo in Rust?

A: The data shows 1920x1080 is the strongest resolution, with the Low preset achieving 149.1 FPS average. At 2560x1440, the Low preset still manages 114.1 FPS, while 3840x2160 drops to 68.2 FPS on Low, indicating 1080p and 1440p are the practical targets.

Q: How does the RX 6700 XT compare to its nearest rivals in raw compute?

A: The RX 6700 XT’s average benchmark score of 33,721 is 0.7% higher than the AMD Radeon RX 6800 (33,493), 1% higher than the AMD Radeon HD 7950 (34,050), and 1.3% higher than the NVIDIA RTX A5000 (33,294). It sits in the 77th percentile among all GPUs.

Q: Does the i5-10400F bottleneck the RX 6700 XT in Rust?

A: The CPU’s benchmark results—a Cinebench R23 multi-core score of 10,297 and single-core score of 1,453—show solid single-thread performance. The data suggests the CPU is not the limiting factor at lower settings, as the FPS scales strongly from 4K to 1080p, indicating the GPU handles the rendering load.

Q: What is the FPS difference between Low and Ultra at 1080p?

A: At 1920x1080, the Low preset averages 149.1 FPS, while Ultra averages 73 FPS. That is a 76.1 FPS gap, or roughly a 104% improvement in average FPS when dropping from Ultra to Low.

Q: Is the RX 6700 XT’s 12 GB VRAM sufficient for Rust at high settings?

A: The GPU features 12 GB of GDDR6 memory on a 192-bit bus with 384.0 GB/s bandwidth. The measured results show that at 3840x2160 High, the average FPS is 38.1, indicating memory capacity is not a limiting factor, but the rendering load is too heavy for playable frame rates at 4K.

Q: How does this combo rank compared to all tested configurations?

A: The combo ranks 965th out of 1,717 tested combinations, placing it in the 56th percentile of all measured systems. This indicates a mid-pack position, with the CPU at the 73rd percentile and GPU at the 77th percentile individually.

GPU Role

The AMD Radeon RX 6700 XT is the dominant component in determining Rust’s performance at higher resolutions. Its 2,560 shading units and 160 texture mapping units, combined with a boost clock of 2,581 MHz, provide the raw compute needed for the game’s environmental rendering. The 12 GB of GDDR6 memory on a 192-bit bus delivers 384.0 GB/s, which is ample for Rust’s asset streaming at 1440p and below.

The GPU’s measured performance shows a clear resolution scaling pattern. At 3840x2160, the Ultra preset averages only 28.8 FPS, which is not playable for a survival game requiring fast reactions. Dropping to High at 4K raises the average to 38.1 FPS, still below the 60 FPS threshold. The Medium preset at 4K yields 46.8 FPS, while Low reaches 68.2 FPS, making it the only 4K option that approaches fluid gameplay.

At 2560x1440, the GPU’s capabilities become more apparent. The Low preset achieves 114.1 FPS, while High hits 62.5 FPS. The Ultra preset at 1440p averages 48.6 FPS, which is marginally playable but not ideal. The data indicates that the GPU’s 13.21 TFLOPS FP32 compute is best utilized at 1440p with medium-to-low settings, where it can maintain frame rates above 75 FPS. The 77th percentile ranking among all GPUs supports this positioning as a strong mid-range performer for this title.

CPU Role

The Intel Core i5-10400F provides six cores and twelve threads, running at a base clock of 2.90 GHz with a boost of 4.30 GHz. This Comet Lake processor, built on the 14 nm process, has 12 MB of shared L3 cache. The single-thread performance is particularly relevant for Rust, which relies heavily on game logic and entity updates.

Benchmark data shows the CPU achieves a Cinebench R23 single-core score of 1,453 and a multi-core score of 10,297. The Geekbench single-core result of 1,454 and multi-core of 5,783 further illustrate its balance. The Passmark single-thread score of 2,541 places it in the 73rd percentile of all CPUs, indicating it performs above average for its generation.

In Rust, the CPU’s role becomes more critical at lower resolutions where the GPU has less work per frame. The measured FPS at 1920x1080 Low (149.1) versus 2560x1440 Low (114.1) shows a 30.7% drop when moving to a higher resolution, suggesting the CPU can feed the GPU adequately at 1080p. The 12 threads help with the game’s background simulation, but the data does not show a bottleneck at 1440p, as the FPS still scales down predictably with increased resolution.

Settings Recommendations

The measured FPS rows provide clear guidance for optimal settings. At 1920x1080, the Low preset delivers 149.1 FPS, which is ideal for high-refresh-rate monitors. The Medium preset at 110.2 FPS is a strong alternative for better visual quality, while High (96.3 FPS) and Ultra (73 FPS) remain playable but with diminishing returns.

For 2560x1440, the Low preset (114.1 FPS) is the best choice for competitive play, while Medium (75.7 FPS) offers a smooth experience with improved visuals. High (62.5 FPS) is acceptable for those prioritizing graphics, but Ultra (48.6 FPS) falls below the 60 FPS threshold and is not recommended for fast-paced gameplay.

At 3840x2160, none of the presets provide a consistently smooth experience. The Low preset (68.2 FPS) is the only option above 60 FPS, but it requires significant visual compromises. Medium (46.8) and High (38.1) are not playable for a survival title, and Ultra (28.8) is effectively a slideshow.

The best experience per the measured rows is 1920x1080 on Medium, offering 110.2 FPS with balanced visuals. For 1440p, Low at 114.1 FPS provides the highest frame rate without dropping below the refresh-rate sweet spot.

How This Combo Ranks

The combo holds rank 965 out of 1,717 tested combinations in Rust, placing it in the lower half of the dataset. This position is curious given the individual component rankings: the CPU sits at the 73rd percentile, and the GPU at the 77th percentile. The combined rank suggests that Rust’s specific workload does not fully leverage either component’s strengths.

The CPU’s nearest rivals in average benchmark score include the AMD EPYC 7552 (0.4% higher score), AMD Ryzen 3 7320C (0.8% lower), and Intel Core i5-8500 (1.1% lower). The GPU’s nearest rivals include the RX 6800 (0.7% higher score) and RTX A5000 (1.3% lower). These deltas are small, indicating the combo sits in a tightly contested performance band.

The rank of 965 out of 1,717 means roughly 56% of tested systems outperform this pairing in Rust. This is likely due to the game’s optimization favoring newer architectures or higher core counts. The combo is not a top-tier performer, but it is far from the bottom, and the measured FPS data shows it can handle the game at mainstream resolutions with adjusted settings.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are as follows: Low preset achieves 149.1 FPS, Medium reaches 110.2 FPS, High delivers 96.3 FPS, and Ultra bottoms out at 73 FPS. The spread from Low to Ultra is 76.1 FPS, showing the heavy cost of the highest settings.

At 2560x1440, the averages are: Low at 114.1 FPS, Medium at 75.7 FPS, High at 62.5 FPS, and Ultra at 48.6 FPS. The gap between Low and Ultra narrows to 65.5 FPS, indicating the GPU becomes more of a limiting factor at this resolution.

At 3840x2160, the results drop significantly: Low averages 68.2 FPS, Medium 46.8 FPS, High 38.1 FPS, and Ultra 28.8 FPS. The difference between Low and Ultra is 39.4 FPS, but all values are below the 60 FPS threshold except Low.

The data shows a consistent pattern: lowering settings yields proportionally larger FPS gains at lower resolutions. At 1080p, moving from Ultra to Low nearly doubles the frame rate (73 to 149.1). At 1440p, the same settings change results in a 135% improvement (48.6 to 114.1). At 4K, the improvement is 137% (28.8 to 68.2). This indicates the GPU’s render pipeline scales efficiently with reduced quality settings across all tested resolutions.
