How This Combo Ranks

In the database of tested combinations, this pairing of Intel Core Ultra 5 225 and AMD Radeon RX 6700 XT ranks 1484 out of 2953 combos in Rust. That places it in the middle of the pack, roughly at the 50th percentile of all tested systems. This rank reflects a balanced pairing where neither component is severely bottlenecking the other, but neither is pushing the system into top-tier territory for this specific title.

The 1484th position out of 2953 indicates that while this combo is entirely capable of running Rust, there are a substantial number of configurations that achieve higher average frame rates. The ranking is driven by the combination of the CPU's 85th percentile overall performance and the GPU's 72nd percentile standing. The CPU is relatively stronger than the GPU in the broader benchmark landscape, which suggests that the graphics card is the more likely limiting factor in this pairing, particularly at higher resolutions and settings where GPU load increases.

Given that the combo sits just past the halfway mark of all tested configurations, users can expect a serviceable Rust experience, but should not anticipate top-tier frame rates at maximum settings. The data shows that this rank is consistent across the measured FPS rows, where the system achieves playable but not exceptional performance, especially when compared to higher-ranked combos that likely feature more powerful GPUs. The mid-pack ranking is a direct reflection of the GPU's moderate position relative to other cards in the database.

GPU Role

The AMD Radeon RX 6700 XT plays a pivotal role in determining Rust's frame rates, particularly as resolution and graphical fidelity increase. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. This memory configuration is sufficient for Rust's asset streaming and texture loading at 1080p and 1440p, but at 4K with High or Ultra settings, the 12 GB capacity and bandwidth become more taxed, contributing to the lower average FPS observed.

The GPU's clock speeds are notably high: a base clock of 2321 MHz, a boost clock of 2581 MHz, and a game clock of 2424 MHz. These clocks are among the higher end for the Radeon RX 6000 series, and they directly influence the fill rate and compute throughput. With a pixel rate of 165.2 GPixel/s and a texture rate of 413.0 GTexel/s, the card can handle Rust's shading and texturing demands at moderate settings, but the 13.21 TFLOPS of FP32 performance is the ceiling for complex scenes.

In Rust, the GPU's role becomes increasingly dominant as resolution rises. At 1080p Low, the CPU is likely the limiting factor, but at 4K Ultra, the GPU's 40 ray accelerators and 64 ROPs are pushed to their limits. The measured FPS data reflects this: at 4K Ultra, the average drops to 29 FPS, while at 1080p Low it reaches 165 FPS. This 5.7x difference in performance is almost entirely attributable to GPU load, as the CPU's workload does not scale as dramatically with resolution. The GPU's 72nd percentile rank among all GPUs further confirms that while it is not a top-tier card, it is capable of delivering playable frame rates in Rust at lower settings, but it struggles to maintain high FPS at 4K with demanding presets.

Measured FPS Breakdown

The measured FPS data for Rust reveals a clear performance hierarchy across resolutions and settings. At 1920x1080, the combo achieves an average of 165 FPS at Low settings, which is the highest figure across all measurements. Medium settings drop to 111 FPS (minimum 94, maximum 127), High settings yield 93 FPS, and Ultra settings bring the average down to 71 FPS. This progression shows a 57% reduction from Low to Ultra at 1080p, indicating that the GPU is increasingly burdened by higher graphical presets.

Moving to 2560x1440, the frame rates scale downward as expected. Low settings average 114 FPS, which is still highly playable. Medium settings average 76 FPS (minimum 65, maximum 88), High settings average 64 FPS, and Ultra settings drop to 49 FPS. The delta between Low and Ultra at 1440p is 57%, similar to the 1080p drop, but the absolute numbers are lower across the board due to the increased pixel count.

At 3840x2160, the performance becomes more constrained. Low settings average 67 FPS, which is the only preset at 4K that crosses the 60 FPS threshold. Medium settings average 45 FPS (minimum 38, maximum 52), High settings average 38 FPS, and Ultra settings average 29 FPS. The drop from Low to Ultra at 4K is 57%, consistent with the other resolutions, but the starting point is much lower, making Ultra effectively unplayable for smooth gameplay.

Across all resolutions, the Medium preset provides the only complete min/max FPS data points, suggesting it is the most stable configuration. At 1080p Medium, the minimum of 94 FPS indicates that even in demanding scenes, the combo maintains a frame rate well above typical 60 FPS targets. At 1440p Medium, the minimum of 65 FPS still meets that threshold, while at 4K Medium, the minimum of 38 FPS falls short. These numbers highlight the GPU-bound nature of higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1920x1080, the Medium preset (111 FPS average, 94 FPS minimum) offers the best balance between visual quality and performance, as it provides a comfortable margin above 60 FPS while maintaining a minimum that rarely stutters. High settings at 1080p (93 FPS average) are also viable for users who prioritize visual fidelity, but the minimum FPS is not captured in the data, introducing some uncertainty. Ultra at 1080p (71 FPS average) is playable but may dip below 60 FPS in heavy scenes.

At 2560x1440, the Medium preset (76 FPS average, 65 FPS minimum) is the recommended choice, as it maintains a minimum above 60 FPS, ensuring smooth gameplay. Low settings (114 FPS average) are overkill for most users, while High (64 FPS average) is borderline, with a minimum that could drop below 60 FPS. Ultra at 1440p (49 FPS average) is not recommended for competitive play, but could be acceptable for less demanding scenarios.

At 3840x2160, only the Low preset (67 FPS average) provides a consistently playable experience. Medium (45 FPS average, 38 FPS minimum) is playable but with noticeable dips, while High (38 FPS) and Ultra (29 FPS) are too slow for smooth gameplay. For 4K users, the data strongly suggests sticking with Low settings to maintain a playable frame rate, or reducing the resolution to 1440p to unlock higher presets. The Medium preset at 1440p delivers a significantly better experience than 4K Low, with 76 FPS average versus 67 FPS, and the visual difference may be worth the resolution trade-off.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake architecture, fabricated on a 3 nm process by TSMC. With a base clock of 3.30 GHz and a boost clock of 4.90 GHz, the CPU delivers strong single-thread performance, as evidenced by its Cinebench R23 single-core score of 3655 and PassMark single-thread score of 4412. This is particularly relevant for Rust, which relies heavily on single-threaded game logic and physics simulation.

The CPU's multi-threaded capabilities are also substantial, with a Cinebench R23 multi-core score of 25891 and a PassMark multi-thread score of 30459. These scores indicate that the CPU can handle the background tasks and server-side calculations that Rust requires, especially in multiplayer scenarios where multiple entities and interactions are simulated. The L3 cache of 20 MB shared across all cores provides adequate data locality for the game's world streaming.

In the context of this combo, the CPU's 85th percentile rank among all CPUs means it is significantly stronger than the GPU's 72nd percentile rank. This imbalance suggests that at lower resolutions and settings, the CPU is more than capable of feeding the GPU, but at higher resolutions, the GPU becomes the bottleneck. The measured FPS data supports this: at 1080p Low, the CPU can push the GPU to 165 FPS, but at 4K Ultra, the GPU's limitations cap the frame rate at 29 FPS. The CPU's 10 threads, while not hyper-threaded, are sufficient for Rust's threading model, which does not typically scale beyond 8-10 threads. The 65W TDP also indicates efficient power delivery, allowing sustained boost clocks without thermal throttling that could impact FPS stability.

Resolution Scaling

The measured FPS data shows a clear pattern of performance degradation as resolution increases, which reveals the limiting component in this combo. From 1920x1080 to 2560x1440, the average FPS at Low settings drops from 165 to 114, a 31% reduction. From 1440p to 4K, the Low settings average drops from 114 to 67, a 41% reduction. Across all settings, the scaling from 1080p to 4K is substantial: Medium drops from 111 to 45 (59% reduction), High drops from 93 to 38 (59% reduction), and Ultra drops from 71 to 29 (59% reduction).

This consistent 57-59% reduction from 1080p to 4K across all settings indicates that the GPU is the primary limiting factor at higher resolutions. If the CPU were the bottleneck, the frame rate would remain relatively flat as resolution increases, since the CPU's workload is largely independent of pixel count. Instead, the data shows a steep decline that aligns with the GPU's fill rate and memory bandwidth constraints. The RX 6700 XT's 384.0 GB/s of bandwidth is sufficient for 1080p and 1440p, but at 4K, the increased pixel throughput demands more than the card can deliver, especially at higher presets.

The scaling also shows that the CPU's headroom is not fully utilized at 4K. At 1080p Low, the CPU pushes the GPU to 165 FPS, but at 4K Low, the same CPU can only achieve 67 FPS, indicating that the GPU is saturated. This suggests that users with a 4K display would benefit more from a GPU upgrade than a CPU upgrade, as the Core Ultra 5 225 has ample performance headroom for this title. Conversely, at 1080p, the combo is more balanced, with the GPU able to keep pace with the CPU's output across most settings. The resolution scaling analysis confirms that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for Low settings or users who prioritize resolution over frame rate.
