Rust

Rust is a demanding survival title, and this pairing of an Intel Core Ultra 5 235 with an AMD Radeon RX 6600 produces a specific and predictable performance profile. The measured data shows a system that can handle 1080p gaming comfortably but struggles significantly as resolution increases, with the GPU becoming the primary constraint. This analysis breaks down the benchmark results across resolutions, component roles, and settings to provide a clear picture of what this combo can deliver.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution climbs from 1080p to 4K. At 1920x1080 with Low settings, the combo achieves 126 FPS average, which drops to 71 FPS at High and 54 FPS at Ultra. Moving to 2560x1440, the Low preset yields 87 FPS, High delivers 49 FPS, and Ultra falls to 37 FPS. At 3840x2160, the numbers become marginal: Low produces 51 FPS, High drops to 29 FPS, and Ultra manages only 22 FPS.

The scaling pattern is telling. From 1080p Low to 4K Low, the average FPS drops by roughly 60%, from 126 to 51. This is a substantial loss, but the frame rate remains technically playable. The more critical observation is how the High and Ultra presets collapse at 4K. At 1080p High, the system holds 71 FPS, but at 4K High it falls to 29 FPS — a 59% reduction. Ultra at 4K produces just 22 FPS, which is below the threshold for smooth gameplay in a survival game where reaction time matters.

The data indicates that the limiting component changes with resolution. At 1080p, the system appears more balanced, with the CPU able to feed the GPU adequately. The jump from 1080p to 1440p at Low settings (126 to 87 FPS) shows a 31% performance hit, which suggests the GPU is starting to feel the load. The transition from 1440p to 4K at Low (87 to 51 FPS) represents another 41% drop, confirming that the RX 6600's rendering capabilities are the bottleneck at higher resolutions. The 8 GB VRAM and 128-bit memory bus become increasingly stressed as pixel count rises, which is reflected in the sharp FPS declines.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip manufactured on a 7 nm process. Its specifications include 1792 shading units, 112 texture mapping units, and 64 raster output pipelines. The GPU operates with a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. Memory consists of 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The card's compute capability is rated at 8.928 TFLOPS FP32, with a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s.

In Rust, the GPU's role becomes evident when comparing the Low and Medium presets across resolutions. At 1080p, Low averages 126 FPS while Medium drops to 85 FPS — a 33% reduction. This gap widens at 1440p, where Low hits 87 FPS and Medium falls to 58 FPS (33% lower). The Medium preset at 4K produces 34 FPS average, with a minimum of 29 and maximum of 40, showing noticeable frame variance.

The 8 GB VRAM capacity is a key factor. Rust's world rendering, especially at higher settings, demands significant memory for textures and draw distances. At 4K Ultra, the system averages just 22 FPS, and the combination of high resolution and Ultra settings likely exceeds what the 224.0 GB/s bandwidth can efficiently feed. The GPU's percentile ranking of 63 among all GPUs places it in the mid-range, and its average benchmark score of 19036 is nearly identical to the NVIDIA Quadro K6000 (19030, 0% delta) and the NVIDIA GeForce RTX 4050 Mobile (19049, -0.1% delta). This indicates the RX 6600 is a solid 1080p-class card that struggles beyond that resolution.

The boost clock of 2491 MHz is relatively high for this class, and the data suggests it helps maintain performance at 1080p. However, the 128-bit memory bus is a limiting factor. At 1440p High, the 49 FPS average indicates the GPU is working hard but cannot sustain higher frame rates. The card's 28 ray accelerators (RT cores) do not meaningfully help in Rust, which is primarily a rasterization-heavy title based on the measured results.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor from the Arrow Lake architecture, built on a 3 nm process by TSMC. It has a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The cache layout includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. Memory support is DDR5 with dual-channel configuration, providing 102.4 GB/s of bandwidth. The CPU supports PCIe Gen 5 with 20 lanes and has a TDP of 65 W.

The CPU's benchmark results show strong single-threaded performance, which is crucial for Rust's game logic and physics. In Cinebench R23, the CPU scores 2085 in single-core and 14769 in multi-core. PassMark single-thread score is 4516, and multi-thread is 37816. The CPU's percentile ranking is 89 among all CPUs, placing it in the upper tier. Its average benchmark score of 46062 is nearly identical to the AMD Ryzen AI 9 HX 375 (46030, 0.1% delta) and the Intel Core i9-13900HX (46098, -0.1% delta), showing it competes with high-end mobile and desktop parts.

In Rust, the CPU's role is most apparent at 1080p Low, where the system achieves 126 FPS. This frame rate suggests the CPU is capable of feeding the GPU without becoming a major bottleneck at lower resolutions. The boost clock of 5.00 GHz helps with single-threaded workloads, which Rust relies on for server-side calculations and entity updates. The 14 cores provide ample multi-threading headroom for background tasks, though Rust is not known for scaling perfectly across many cores.

The data shows that at 1080p, the CPU can push the GPU to its limits. The difference between 1080p Low (126 FPS) and 1440p Low (87 FPS) is 39 FPS, which is primarily a GPU limitation. However, at 4K Low, the 51 FPS average indicates the GPU is heavily constrained, and the CPU has significant headroom. The CPU's memory bandwidth of 102.4 GB/s is adequate for this pairing, and the L3 cache at 24 MB helps with game data locality.

How This Combo Ranks

The combo rank in Rust is 2280 out of 2953 tested combinations, placing it in the bottom quarter of all tested systems. This ranking reflects the GPU's mid-range status (63rd percentile among all GPUs) paired with a strong CPU (89th percentile among all CPUs). The discrepancy between the CPU's high percentile and the GPU's mid-range percentile explains the overall ranking: the CPU has significant headroom, but the GPU holds the system back.

The ranking suggests that this combo is best suited for 1080p gaming. At 1080p Low, the system achieves 126 FPS, which is competitive for fast-paced survival gameplay. At 1080p High, the 71 FPS average is still smooth, and the Medium preset at 85 FPS offers a balanced experience. The ranking also indicates that many other combinations outperform this setup at higher resolutions, where the RX 6600's limitations become apparent.

Compared to other combos in the database, this pairing sits below the median. The CPU's strong single-threaded performance (2085 in Cinebench R23 single-core) does not compensate for the GPU's 8 GB VRAM and 128-bit bus at higher resolutions. The combo's performance at 1440p High (49 FPS) and 4K High (29 FPS) places it in a range where many users would find the experience unsatisfactory for a game like Rust, which requires consistent frame rates for building, combat, and exploration.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution. At 1920x1080, the Low preset delivers 126 FPS, which is excellent for competitive play where reaction time matters. The Medium preset at 85 FPS offers a visual upgrade while maintaining smooth gameplay, and the High preset at 71 FPS is still playable. The Ultra preset at 54 FPS is borderline, and the visual gains may not justify the 43% drop from Medium to Ultra.

At 2560x1440, the Low preset produces 87 FPS, which is the only setting that provides a consistently smooth experience. The Medium preset at 58 FPS is playable but may suffer in busy scenes. The High preset at 49 FPS and Ultra at 37 FPS are not recommended for active gameplay, as they fall below the threshold for comfortable play in a survival game where sudden frame drops can be fatal.

At 3840x2160, none of the presets deliver acceptable performance. The Low preset at 51 FPS is the only option that approaches playability, but even this is marginal. The Medium preset at 34 FPS (minimum 29, maximum 40) shows significant frame variance, which can cause stuttering. High at 29 FPS and Ultra at 22 FPS are not viable for actual gameplay.

The best experience per the measured rows is 1080p Medium, which balances visual quality with a 85 FPS average and a minimum of 72 FPS. This preset provides a 32% boost over High (71 FPS) while maintaining smoother minimum frame rates than the Ultra preset. For users who prioritize frame rate above all else, 1080p Low at 126 FPS is the clear choice. At 1440p, Low is the only recommended preset, as it is the sole option that stays above 60 FPS. The data consistently shows that this combo is a 1080p-oriented solution, and pushing beyond that resolution requires significant compromises in visual fidelity.
