Rust

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4080 delivers a highly capable Rust experience, with the data showing that the most demanding playable preset scales cleanly with resolution. At 1080p and 1440p, the combination can run the Ultra preset comfortably above 60 FPS, while at 4K, the High preset is the ceiling for smooth gameplay. This pairing ranks in the top quarter of all tested combos, indicating that the RTX 4080’s immense graphics power compensates for the older six-core CPU. The recorded data confirms that this is a system built for high-refresh-rate Rust at standard resolutions, with 4K requiring a slight settings compromise to maintain fluidity.

Best Settings per Resolution

The database verdict, based on a 60 FPS playability threshold, identifies the most demanding preset that stays at or above that mark for each resolution.

At 3840x2160, the best playable setting is High, yielding an average of 66 FPS. The Ultra preset drops to 50 FPS, which falls below the playable threshold, while Medium and Low remain viable at 79 FPS and 110 FPS respectively. The data shows a clear boundary: High is the highest visual quality that keeps the frame rate above 60 at 4K.

For 2560x1440, the best settings is Ultra, with an average of 85 FPS. Every preset tested at this resolution stays above the 60 FPS floor, including High at 106 FPS, Medium at 113 FPS, and Low at 131 FPS. This means the system has enough headroom to run the game at its highest visual fidelity without issue.

At 1920x1080, the best settings is also Ultra, delivering an average of 109 FPS. The performance hierarchy is consistent, with High at 121 FPS, Medium at 128 FPS, and Low at 149 FPS. The 1080p results indicate that the combo is never bottlenecked by the CPU in a way that prevents the Ultra preset from exceeding the 60 FPS target.

How This Combo Ranks

The database places this CPU-GPU combination at rank 892 out of 3,723 tested combos for Rust. This means the pair outperforms roughly three-quarters of all recorded system configurations, placing it in the top 24% of the database. The rank reflects a well-balanced pairing for this title, though it is not a top-tier enthusiast setup, likely due to the CPU’s position in the overall performance spectrum.

The GPU is the dominant component here, with a percentile rank of 86 against all GPUs, while the CPU holds a percentile rank of 68 against all CPUs. The combination’s game-specific rank of 892 is therefore heavily influenced by the graphics card, which is capable of pushing high frame rates across all tested resolutions. The CPU, while not weak, is the limiting factor in certain low-resolution, high-FPS scenarios, as evidenced by the smaller FPS gains when moving from 1440p to 1080p.

Measured FPS Breakdown

The recorded measurements show a consistent pattern across settings and resolutions. The following data is directly from the database.

3840x2160 (4K):

• Low: average 110 FPS, no min or max recorded.
• Medium: average 79 FPS, with a minimum of 67 FPS and a maximum of 90 FPS.
• High: average 66 FPS, no min or max recorded.
• Ultra: average 50 FPS, no min or max recorded.

2560x1440 (1440p):

• Low: average 131 FPS, no min or max recorded.
• Medium: average 113 FPS, with a minimum of 96 FPS and a maximum of 130 FPS.
• High: average 106 FPS, no min or max recorded.
• Ultra: average 85 FPS, no min or max recorded.

1920x1080 (1080p):

• Low: average 149 FPS, no min or max recorded.
• Medium: average 128 FPS, with a minimum of 109 FPS and a maximum of 147 FPS.
• High: average 121 FPS, no min or max recorded.
• Ultra: average 109 FPS, no min or max recorded.

The data indicates that moving from Low to Ultra at 4K reduces the average FPS by 55% (from 110 to 50). At 1440p, the reduction is 35% (from 131 to 85), and at 1080p it is 27% (from 149 to 109). The Medium preset consistently offers a significant bump over Low, but the gap between High and Ultra is noticeably larger at 4K (16 FPS) than at 1440p (21 FPS) or 1080p (12 FPS), suggesting the GPU is more stressed at 4K.

Similar Performance Alternatives

Based on the nearest rivals in the database, the CPU and GPU each have close performance matches that would produce similar frame rates in Rust.

For the CPU (Intel Core i5-10400F, average score 14,185), the closest alternatives are:

• Intel Xeon 6756E with a score of 14,163, which is 0.2% slower.
• Intel Core 7 160UL with a score of 14,232, which is 0.3% faster.
• AMD EPYC 7552 with a score of 14,115, which is 0.5% slower.
• AMD Ryzen 3 7320C with a score of 14,277, which is 0.6% faster.

These rivals are within a fraction of a percent, so any of these CPUs would yield nearly identical CPU-bound performance in Rust. The differences are negligible in practice, meaning swapping the i5-10400F for any of these would not materially change the FPS results.

For the NVIDIA GeForce RTX 4080, the nearest rivals are:

• NVIDIA GeForce RTX 4080 SUPER with a score of 54,209, which is 0.1% slower.
• AMD Radeon Pro W5700X with a score of 54,828, which is 1.1% faster.
• AMD Radeon RX 6750 GRE 12 GB with a score of 55,698, which is 2.6% faster.
• AMD Radeon 8060S with a score of 55,757, which is 2.7% faster.

The RTX 4080 SUPER is essentially a direct match, with a 0.1% delta that is within measurement noise. The AMD alternatives are slightly faster in synthetic benchmarks, but the 2.7% difference would translate to a negligible FPS advantage in Rust, likely a few frames per second at most.

CPU and GPU Roles

The data reveals a clear shift in component responsibility depending on resolution. At 4K, the GPU dominates the performance ceiling. The average FPS drops sharply when moving from Low (110) to Ultra (50), a 55% decrease, while the CPU is less likely to be the limiting factor due to the high pixel count. The GPU’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are fully utilized at this resolution.

At 1440p, the balance tips. The difference between Low (131) and Ultra (85) is 46 FPS, a 35% reduction, which is smaller than at 4K. This suggests that the CPU is beginning to hold back the GPU, especially at lower settings where the CPU can affect frame pacing. The CPU’s six cores and 12 threads, with a max boost of 4.30 GHz, are sufficient to keep the GPU fed, but the scaling between presets is less dramatic.

At 1080p, the CPU matters most. The FPS range from Low (149) to Ultra (109) is a 27% drop, the smallest relative decrease across all resolutions. The high average frame rates, exceeding 100 FPS in all cases, indicate that the CPU is the primary bottleneck at this resolution, as the GPU has ample headroom to render the scene. The CPU’s percentile rank of 68 makes it a mid-range performer, and in Rust, a game that is heavily dependent on single-core performance, the 3dmark single-thread score of 688 and the passmark single-thread of 2541 suggest it can handle the load but does not provide the same headroom as the GPU.

The data shows that for maximum FPS at 1080p, the CPU is the key component, while at 4K, the GPU dictates performance. The 1440p results fall in between, with the CPU still influential but the GPU starting to dominate the settings scaling.
