# Rust: Intel Core Ultra 5 225 + NVIDIA GeForce RTX 5080 — Benchmark Analysis

The combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 5080 produces a wide spread of frame rates across resolutions and settings in Rust, ranging from 52 FPS at 4K Ultra to 258 FPS at 1080p Low. The dataset shows a system that is heavily GPU-limited at higher resolutions but becomes increasingly CPU-bound as resolution drops, with the measured results revealing distinct scaling patterns that inform both component roles and optimal settings.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic resolution-scaling curve, but with notable deviations that indicate where the bottleneck shifts. At 1080p High, the combo delivers 169 FPS; moving to 1440p High drops this to 116 FPS, a reduction of 53 FPS or roughly 31%. The subsequent jump to 4K High yields 69 FPS, which is another 47 FPS decline, or about 41% lower than the 1440p result. This steepening decline as resolution increases points to the GPU becoming the limiting factor at 4K, where the RTX 5080’s rendering workload scales with pixel count.

Analyzing the Low preset across resolutions provides the clearest view of CPU versus GPU limitations. At 1080p Low, the system reaches 258 FPS, while 1440p Low produces 205 FPS, and 4K Low drops to 121 FPS. The 1080p-to-1440p gap is 53 FPS (about 21% reduction), while the 1440p-to-4K gap is 84 FPS (about 41% reduction). The larger proportional drop at higher resolutions confirms that even with minimal graphical settings, the GPU becomes the primary constraint as pixel count increases. However, the fact that 1080p Low (258 FPS) is substantially higher than 1080p High (169 FPS) — a 89 FPS difference — indicates that at 1080p, the CPU is capable of feeding the GPU far more frames than the GPU can render at High settings.

The Medium preset shows similar scaling: 200 FPS at 1080p, 138 FPS at 1440p, and 81 FPS at 4K. The Ultra preset, which is the most demanding, yields 129 FPS at 1080p, 88 FPS at 1440p, and only 52 FPS at 4K. The Ultra scaling is particularly steep — the 1440p-to-4K drop of 36 FPS (about 41%) mirrors the High preset’s proportional decline, suggesting that at Ultra settings, the GPU is consistently the bottleneck across all resolutions. Notably, the 4K Ultra result of 52 FPS is the only measured average below 60 FPS, indicating that this combination struggles to maintain smooth gameplay at maximum settings in 4K.

FAQ

Q: What is the highest average frame rate this combo achieves in Rust?

A: The highest measured average is 258 FPS at 1920x1080 with Low settings. The next highest is 205 FPS at 2560x1440 with Low settings, followed by 200 FPS at 1080p Medium.

Q: Can this system maintain 60+ FPS at 4K in Rust?

A: Yes, but not at the highest settings. At 4K High, the average is 69 FPS; at 4K Medium, it drops to 81 FPS; at 4K Low, it reaches 121 FPS. However, at 4K Ultra, the average falls to 52 FPS, which is below the 60 FPS threshold.

Q: What is the frame time variance like at Medium settings?

A: The data includes minimum and maximum FPS for Medium presets. At 1080p Medium, the range is 170–230 FPS (average 200). At 1440p Medium, the range is 117–158 FPS (average 138). At 4K Medium, the range is 69–94 FPS (average 81).

Q: How does the RTX 5080’s 16 GB VRAM factor into these results?

A: The 16 GB GDDR7 memory with 960.0 GB/s bandwidth is sufficient for all tested settings. The measured frame rates show no indication of VRAM capacity being a limiting factor, as even the lowest average (52 FPS at 4K Ultra) is more likely constrained by compute throughput than memory capacity.

Q: Which preset provides the largest performance headroom above 60 FPS at 1440p?

A: At 1440p, all settings exceed 60 FPS. The closest to the threshold is Ultra at 88 FPS, while High (116 FPS), Medium (138 FPS), and Low (205 FPS) all provide substantial margins.

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

A: At 1080p, Low averages 258 FPS while Ultra averages 129 FPS — exactly half the frame rate. This 129 FPS difference represents a 100% performance gap between the two extremes.

The proportional gaps between settings at 1440p are similar to 1080p: Low to Medium is a 67 FPS drop (33% lower), Medium to High is 22 FPS (16% lower), and High to Ultra is 28 FPS (24% lower). The consistency of these percentages across resolutions suggests that the relative cost of each settings tier is stable.

At 3840x2160, the averages are 52 FPS (Ultra), 69 FPS (High), 81 FPS (Medium), and 121 FPS (Low). The Medium preset ranges from 69 to 94 FPS. The Low-to-Medium gap is 40 FPS (33% lower), Medium-to-High is 12 FPS (15% lower), and High-to-Ultra is 17 FPS (25% lower). This 4K data shows the same proportional scaling as lower resolutions, but with absolute values compressed into a lower range — the entire spread from Ultra to Low is 69 FPS at 4K, compared to 129 FPS at 1080p.

GPU Role

The RTX 5080’s specifications — 10,752 shading units, 336 texture mapping units, 112 raster output units, 84 RT cores, and 336 tensor cores — provide the compute foundation for Rust’s rendering workload. The boost clock of 2617 MHz and base clock of 2295 MHz define the operating frequency envelope, while the pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s quantify the theoretical fill and texturing throughput.

The 16 GB VRAM on a 256-bit bus with 960.0 GB/s bandwidth is a critical resource for Rust, a game known for large, persistent worlds with substantial texture and asset streaming. None of the measured results suggest VRAM bottlenecks — even at 4K Ultra, where memory pressure would be highest, the average of 52 FPS is consistent with compute limitations rather than capacity constraints. The memory clock of 1875 MHz (30 Gbps effective) provides ample bandwidth for the game’s data demands.

The GPU’s benchmark profile shows a PassMark G3D score of 36,565 and an average benchmark score of 56,083, placing it in the 87th percentile of all GPUs. In Rust specifically, the GPU’s role as the primary bottleneck at higher resolutions is evident from the scaling data: at 4K, even Low settings only reach 121 FPS, while at 1080p Low the system nearly doubles that. This indicates that at 4K, the GPU is working near its limits regardless of settings, while at 1080p, there is substantial headroom that the CPU can exploit.

CPU Role

The Intel Core Ultra 5 225 features 10 cores and 10 threads, with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. This configuration, based on the Arrow Lake-S architecture on a 3 nm process, provides the processing foundation for Rust’s simulation and game logic. The CPU’s cache hierarchy includes 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3 cache, which supports the game’s server-side entity processing and world state management.

The CPU’s benchmark results show strong single-thread performance: a Cinebench R23 single-core score of 3,655 and a PassMark single-thread score of 4,412. Multi-threaded performance is also solid, with a Cinebench R23 multi-core score of 25,891 and a PassMark multi-thread score of 30,459. These figures, combined with the CPU’s 85th percentile ranking, indicate that the Core Ultra 5 225 is a capable gaming processor.

In Rust, the CPU’s role is most evident at 1080p, where the system achieves 258 FPS at Low settings. This high frame rate suggests the CPU can feed the GPU with enough frames to exceed 250 FPS when graphical load is minimal. However, the fact that 1080p Ultra drops to 129 FPS — the same as 1440p Ultra (88 FPS) scaled — shows that as GPU load increases, the CPU becomes less relevant. The 4K Low result of 121 FPS, which is close to the 1080p Ultra result of 129 FPS, further indicates that at 4K, the GPU is the dominant constraint even at low settings.

The CPU’s memory support for DDR5 with dual-channel configuration and 102.4 GB/s bandwidth provides adequate data throughput for game assets. The 20 MB shared L3 cache helps mitigate latency for frequently accessed data, which can be beneficial in Rust’s open-world environment where many entities are active simultaneously.

Settings Recommendations

Based on the measured data, the optimal settings depends on the target resolution and desired frame rate. For 4K gameplay, High settings (69 FPS average) provide a playable experience above 60 FPS, while Medium (81 FPS) offers a more comfortable margin. Ultra at 4K (52 FPS) falls below the 60 FPS threshold and is not recommended for smooth gameplay. Low at 4K (121 FPS) delivers the highest frame rate but sacrifices visual fidelity.

At 1440p, all settings exceed 60 FPS, but the choices present a trade-off between frame rate and visual quality. Ultra (88 FPS) is playable, but High (116 FPS) provides a significantly smoother experience with only modest visual differences. Medium (138 FPS) and Low (205 FPS) offer even higher frame rates, with Medium providing the best balance of visuals and performance for competitive play. The Medium preset’s min-max range of 117–158 FPS indicates consistent frame delivery.

For 1080p, the system has substantial headroom. Ultra (129 FPS) provides maximum visual quality while still maintaining a high frame rate. High (169 FPS) is ideal for high-refresh-rate monitors. Medium (200 FPS) and Low (258 FPS) are suitable for competitive play where frame rate is prioritized over visuals. The Medium preset at 1080p shows a range of 170–230 FPS, demonstrating excellent consistency.

The data suggests that Medium settings offer the best overall experience across resolutions: it provides the highest minimum FPS confidence (69 FPS at 4K, 117 FPS at 1440p, 170 FPS at 1080p) while maintaining reasonable visual quality. For users with 4K displays seeking smooth gameplay, High settings are the recommended ceiling. For 1440p and 1080p users, Ultra and High settings respectively offer the best balance of performance and visual fidelity, with Medium available as a competitive alternative.
