Rust

Rust is a demanding survival title that stresses both CPU and GPU heavily, and the combination of the Intel Core Ultra 5 225 with the NVIDIA GeForce RTX 3080 Ti produces a wide spread of performance across resolutions and presets. The measured data shows a system that can deliver high refresh rates at 1080p but becomes increasingly GPU-bound as resolution climbs, with the 4K Ultra preset dipping below 40 FPS. This pairing ranks in the 78.6th percentile of all tested combos in this specific game, indicating a strong but not elite configuration.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and clearly exposes the GPU as the primary limiting factor at higher resolutions. At Low settings, the average frame rate falls from 224 FPS at 1920x1080 to 154 FPS at 2560x1440, a reduction of 31.3%, and then further down to 91 FPS at 3840x2160, representing a 59.4% drop from the 1080p baseline. This scaling pattern is typical for a title where pixel throughput becomes the bottleneck as resolution increases.

The Medium preset shows a similar trend, with averages of 150 FPS at 1080p, 103 FPS at 1440p, and 61 FPS at 4K. The drop from 1440p to 4K is particularly steep at 40.8%, while the 1080p to 1440p transition costs 31.3% of performance. This suggests that the RTX 3080 Ti, with its 12 GB of GDDR6X memory and 912.4 GB/s bandwidth, is well-equipped for 1440p but starts to struggle with the sheer pixel count at 4K.

Interestingly, the High preset exhibits a slightly different scaling curve, moving from 127 FPS at 1080p to 87 FPS at 1440p and 52 FPS at 4K. The percentage drops here are 31.5% and 40.2% respectively, which are less severe than the Low preset's falloff. This indicates that at higher quality settings, the workload shifts somewhat toward the GPU's shading and texture units, which the 34.10 TFLOPS FP32 compute and 532.8 GTexel/s texture rate handle more efficiently than raw fill-rate-limited scenarios.

The data reveals that the Core Ultra 5 225 is not the limiting factor at any resolution above 1080p. At 1080p Low, the CPU's 10 cores and 10 threads with a 4.90 GHz boost clock are likely near their performance ceiling, but the substantial frame rate of 224 FPS suggests it keeps pace adequately. As resolution increases, the GPU's workload grows disproportionately, and the CPU headroom becomes irrelevant, confirming that the RTX 3080 Ti is the bottleneck at 1440p and especially at 4K.

How This Combo Ranks

Within the database of tested combinations for Rust, this specific pairing of the Intel Core Ultra 5 225 and the NVIDIA GeForce RTX 3080 Ti achieves a rank of 633 out of 2953 total combos. This places it in the top 21.4% of all configurations tested, which is a strong showing for a mid-range CPU paired with a previous-generation high-end GPU. The percentile ranking of 78.6% against all CPUs in general benchmarks further contextualizes the processor's capability.

The combo's ranking suggests that while the RTX 3080 Ti is a powerful card, its age relative to newer offerings prevents this pairing from reaching the upper echelons of the leaderboard. The GPU's average benchmark score of 41187 places it in the 83rd percentile of all GPUs, slightly above its nearest rival, the NVIDIA GeForce RTX 5070, which scores 40377 with a deltaPct of 2%. This indicates that the 3080 Ti remains competitive with newer mid-range cards, but the combination with the Core Ultra 5 225 does not boost it to top-tier status in Rust specifically.

The CPU's nearest rivals in general benchmarks include the AMD Ryzen 5 5600F with an average score of 36945 and a 0% delta, and the AMD Ryzen 5 5500X3D at 37018 with a -0.2% delta. These near-identical scores suggest that the Core Ultra 5 225 performs on par with these competitors in synthetic tests. In Rust, which is known to favor single-threaded performance and cache hierarchy, the 20 MB of shared L3 cache and 4.90 GHz boost clock likely contribute to the combo's respectable ranking, but the lack of additional threads beyond 10 may hinder performance in heavily populated server scenarios.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing for determining frame rates at higher resolutions. Its GA102 chip, built on Samsung's 8 nm process, contains 28,300 million transistors across a 628 mm² die. The card operates at a base clock of 1365 MHz and a boost clock of 1665 MHz, which are modest figures for a high-end GPU, but the sheer scale of the architecture compensates with 10,240 shading units and 112 ROPs.

Memory configuration plays a critical role in Rust's performance. The 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth, which is essential for the game's large open-world textures and asset streaming. At 4K Ultra settings, the average FPS drops to 39, suggesting that the memory bandwidth and capacity are being pushed to their limits. The 3840x2160 Medium preset shows a minimum FPS of 52 and a maximum of 70, with an average of 61, indicating that the card can maintain playable frame rates at 4K with reduced settings.

The GPU's compute capabilities are substantial, with 34.10 TFLOPS of FP32 throughput and 34.10 TFLOPS of FP16. This raw compute power is likely why the Low preset at 1080p achieves 224 FPS, as the game's simpler shading workloads are easily handled. The 80 RT cores and 320 tensor cores provide additional capabilities that Rust may not fully utilize, but they contribute to the card's overall benchmark scores, including a 3DMark Steel Nomad DX12 score of 5077 and a Passmark G3D score of 26896.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear hierarchy across settings. Low settings deliver an average of 224 FPS, which is the highest measured frame rate for this combo. Medium settings reduce this to 150 FPS on average, with a minimum of 128 FPS and a maximum of 173 FPS. High settings further lower the average to 127 FPS, while Ultra settings bring the average down to 96 FPS. The spread from Low to Ultra at 1080p is 128 FPS, representing a 57.1% performance penalty for maximum quality.

Moving to 2560x1440, the averages drop across all presets. Low settings maintain an average of 154 FPS, which is still highly playable for competitive scenarios. Medium settings average 103 FPS with a range of 88 to 119 FPS. High settings deliver 87 FPS on average, and Ultra settings fall to 66 FPS. The scaling from Low to Ultra at 1440p shows a 57.1% reduction, mirroring the 1080p pattern, which indicates that the GPU is handling the increased resolution proportionally.

At 3840x2160, the performance becomes more constrained. Low settings average 91 FPS, which is the only 4K preset above 60 FPS. Medium settings average 61 FPS with a minimum of 52 FPS and a maximum of 70 FPS, providing a borderline playable experience. High settings drop to 52 FPS on average, and Ultra settings fall to 39 FPS. The gap between Low and Ultra at 4K is 52 FPS, a 57.1% reduction, consistent with the other resolutions. This consistency suggests that the RTX 3080 Ti scales predictably with settings across all resolutions, and the 12 GB of VRAM does not cause a sudden cliff at 4K.

CPU Role

The Intel Core Ultra 5 225, with its 10 cores and 10 threads, is a capable processor for Rust, but its role in this combo diminishes as resolution increases. The CPU's base clock of 3.30 GHz and boost clock of 4.90 GHz, combined with 20 MB of shared L3 cache, provide strong single-threaded performance, which is crucial for Rust's simulation and physics calculations. In Cinebench R23, the CPU scores 3655 in single-core and 25891 in multi-core, placing it in the 85th percentile of all CPUs.

At 1080p Low, the CPU is likely the limiting factor, as the 224 FPS average exceeds what most users can display but may be constrained by the processor's thread count. The lack of hyperthreading, with only 10 threads for 10 cores, could cause occasional stutters in scenarios with many entities or players. However, the 4.90 GHz boost clock helps mitigate this, and the Passmark single-thread score of 4412 indicates robust per-core performance.

The CPU's memory bandwidth of 102.4 GB/s over a dual-channel DDR5 interface is sufficient for the game's data streaming, but it is notably lower than the GPU's 912.4 GB/s bandwidth. This disparity means that the CPU cannot feed the GPU fast enough at lower resolutions, but at 1440p and above, the GPU's rendering workload becomes the bottleneck. The processor's 3 nm process node from TSMC and 17,800 million transistors indicate an efficient design that produces strong results in Passmark's multithread test with a score of 30459.

Settings Recommendations

For users seeking the best balance of visual quality and performance at 1920x1080, the High preset is the recommended starting point. With an average of 127 FPS, it provides a smooth experience while maintaining better visual fidelity than Medium. However, for competitive play where frame rate is paramount, the Low preset's 224 FPS average offers the highest responsiveness, though it sacrifices graphical detail. The Ultra preset at 96 FPS is still playable but may not be worth the visual improvements over High for most users.

At 2560x1440, the Medium preset emerges as the sweet spot, delivering an average of 103 FPS with a minimum of 88 FPS. This provides a comfortable margin above 60 FPS while offering better visuals than Low. The High preset at 87 FPS is also viable, but the 15.5% performance drop from Medium may not justify the modest visual gain. The Low preset at 154 FPS is excellent for high-refresh-rate monitors, but the Ultra preset at 66 FPS is only recommended for users who prioritize image quality over frame rate stability.

For 3840x2160, the Medium preset is the only reasonable choice for a playable experience, with an average of 61 FPS and a minimum of 52 FPS. This allows for smooth gameplay on most displays, though the minimum FPS may dip below 60 in intense scenes. The Low preset at 91 FPS is acceptable for users who prefer higher frame rates, but it significantly reduces visual quality. The High and Ultra presets at 52 and 39 FPS respectively should be avoided for general play, as they fall below the threshold for smooth motion. Users targeting 4K should consider lowering the resolution or accepting the Medium preset's compromises.
