Rust

The Intel Core Ultra 5 235 paired with the AMD Radeon RX 580 produces a benchmark profile in Rust that is heavily constrained by the graphics card, particularly at higher resolutions and settings. The data indicates a configuration that can handle the game at 1080p with adjusted settings, but which falls below playable thresholds at 4K. This analysis breaks down the measured performance to identify the optimal settings and the respective roles of the CPU and GPU.

Settings Recommendations

Based on the measured FPS rows, the most balanced experience for this combo is the Low preset at 1920x1080, which yields an average of 74 FPS. This is the only setting and resolution combination that approaches high refresh rate territory. The data shows a clear trade-off: at 1080p, moving from Low to Medium drops the average from 74 to 49 FPS, a 34% reduction. Selecting High further reduces performance to 42 FPS, and Ultra falls to 32 FPS. While 32 FPS is technically playable for some, the jump from Low to Ultra represents a 57% performance penalty.

For users prioritizing visual fidelity over frame rate, the Medium preset at 1920x1080 is the highest settings tier that maintains an average above 45 FPS. The Medium preset also provides the only complete FPS data (min/max) in the entire dataset at 1080p, with a range of 42 to 57 FPS. This indicates a degree of stability that is absent in the High and Ultra presets, which lack min/max measurements. The data does not support using higher presets at 1440p, as even Low settings only achieve 51 FPS average, and the High preset dips to 29 FPS.

At 2560x1440, the Low preset remains the most viable option, with an average of 51 FPS. However, this is borderline for fast-paced survival gameplay. The 4K resolution is not recommended for any preset, as the highest average FPS recorded is 30 at Low settings, with Ultra dropping to 13 FPS. The performance scaling from Low to Ultra at 4K is severe, with a 57% drop in average FPS, mirroring the 1080p trend but starting from a much lower baseline.

FAQ

Q: Can this CPU and GPU combination run Rust at 4K resolution?

A: The data indicates that 4K is not a viable option for this combo. The highest average FPS recorded at 3840x2160 is 30 FPS on the Low preset. The Medium preset averages 20 FPS, and the Ultra preset averages 13 FPS. These results are well below the threshold for smooth gameplay.

Q: What is the best settings preset for 1080p gaming with this hardware?

A: The Low preset at 1920x1080 provides the best performance with an average of 74 FPS. If visual quality is more important, the Medium preset is the highest setting that maintains an average above 45 FPS, with a measured range of 42 to 57 FPS.

Q: How does the FPS drop when moving from 1080p to 1440p?

A: The scaling is consistent across presets. For the Low preset, the average FPS drops from 74 at 1080p to 51 at 1440p, a 31% decrease. For the High preset, the average drops from 42 to 29 FPS, a 31% decrease. This consistent scaling points to a GPU-bound scenario.

Q: Is the CPU or the GPU the limiting factor in this game?

A: The benchmark results indicate the GPU is the primary bottleneck. The consistent percentage drop in FPS as resolution increases (a purely GPU-centric workload) suggests the CPU has headroom. The Intel Core Ultra 5 235, with its 14 cores and high single-thread performance metrics, is not the constraining component in these tests.

Q: What is the performance difference between the Low and Ultra presets?

Q: Does the combo rank high among tested systems for Rust?

A: No. The combo ranks 2683 out of 2953 tested combinations. This places it in the lower percentile of systems, indicating that the overall performance is below average for this specific game.

Resolution Scaling

The measured data shows a clear and predictable pattern of FPS degradation as resolution increases from 1920x1080 to 3840x2160. For the Low preset, the average FPS drops from 74 at 1080p to 51 at 1440p, and finally to 30 at 4K. This represents a 31% drop from 1080p to 1440p, and a further 41% drop from 1440p to 4K. The High preset follows a similar trajectory: 42 FPS at 1080p, 29 FPS at 1440p, and 17 FPS at 4K.

The consistent percentage drops between 1080p and 1440p across different presets (31% for Low, 31% for High) point to a system that is firmly GPU-limited. The GPU must render more pixels, and the frame rate scales inversely with the pixel count. The RX 580's memory bandwidth of 256.0 GB/s and 8 GB of GDDR5 memory are sufficient for capacity, but the processing power is insufficient for higher resolutions in this game. The 4K results are particularly telling; even the Low preset struggles to maintain 30 FPS, and the Ultra preset is almost unplayable at 13 FPS. This scaling behavior confirms that the resolution is the primary factor in performance degradation, and the CPU is not the limiting factor in these scenarios.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235 and the AMD Radeon RX 580 ranks 2683 out of 2953 tested combos in Rust. This places it in the bottom 10% of all tested systems, highlighting that this is not a performance-oriented pairing for this title. The low rank is consistent with the measured FPS data, which shows the system struggling to maintain high frame rates even at 1080p with lower settings.

This rank does not reflect the CPU's capabilities, as the Core Ultra 5 235 scores in the 89th percentile of all CPUs, with an average benchmark score of 46062. The bottleneck is clearly the GPU, which sits in the 53rd percentile of all GPUs. The combination of a high-end CPU with a mid-range, end-of-life GPU creates a significant imbalance for gaming workloads. The data suggests that the GPU is holding back the system's overall potential in this game, preventing the CPU from demonstrating its full strength. The ranking is a direct consequence of the GPU's performance ceiling, not a fault of the processor.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor based on the Arrow Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. Its benchmark scores are strong, with a Cinebench R23 multi-core score of 14769 and a single-core score of 2085. The Passmark single-thread score of 4516 is particularly relevant for gaming, as many game engines rely heavily on single-thread performance.

In Rust, the data suggests that the CPU is not the primary bottleneck. The evidence for this is the consistent scaling of FPS with resolution. If the CPU were the limiting factor, the FPS would remain relatively flat across different resolutions. However, we see a clear drop from 74 FPS at 1080p to 51 FPS at 1440p on the Low preset, indicating that the GPU is struggling to keep up with the increased pixel count. The CPU has 24 MB of shared L3 cache and supports DDR5 memory with a bandwidth of 102.4 GB/s, which provides ample headroom for game logic and asset streaming. The 5.00 GHz boost clock ensures that the processor can handle the single-threaded tasks that Rust requires without becoming a constraint. The CPU's performance is effectively masked by the GPU's limitations in this configuration.

Measured FPS Breakdown

At 1920x1080, the measured average FPS is 74 on Low, 49 on Medium, 42 on High, and 32 on Ultra. The Medium preset shows a min FPS of 42 and a max FPS of 57, indicating a 15 FPS variance. The Low preset offers the best performance, but the step up to Medium incurs a 34% performance penalty. High and Ultra presets provide diminishing returns in visual quality for significant frame rate losses.

At 2560x1440, the average FPS drops to 51 on Low, 34 on Medium, 29 on High, and 22 on Ultra. The Medium preset at this resolution shows a min FPS of 29 and a max of 39. The performance gap between Low and Medium is 33%, similar to the 1080p results. The High and Ultra presets are below 30 FPS, which is generally considered the minimum for playable frame rates in a survival game.

At 3840x2160, the average FPS is 30 on Low, 20 on Medium, 17 on High, and 13 on Ultra. The Medium preset shows a min FPS of 17 and a max of 23. All presets at 4K are below 30 FPS, making the game essentially unplayable. The performance drops are severe, with the Ultra preset delivering only 43% of the Low preset's frame rate. The data across all resolutions shows a consistent pattern where the GPU is the limiting factor, as the FPS scales directly with the rendering resolution.

GPU Role

The AMD Radeon RX 580 is based on the Polaris 20 chip and the GCN 4.0 architecture, built on a 14 nm process. It features 2304 shading units, 144 TMUs, and 32 ROPs. The GPU has a base clock of 1257 MHz and a boost clock of 1340 MHz, with 8 GB of GDDR5 memory on a 256-bit bus providing 256.0 GB/s of bandwidth. Its compute capability is rated at 6.175 TFLOPS for FP32 operations.

In Rust, the RX 580 is the definitive bottleneck. The benchmark results show that the GPU's performance is insufficient for high-resolution gaming. The card's 53rd percentile ranking among all GPUs and its average benchmark score of 12928 place it in the mid-range category, and its end-of-life production status indicates it is an older design. The nearest rival data shows it is comparable to the NVIDIA GeForce GTX 1660 SUPER, with a negligible delta of -0.4%, but this performance level is not enough for demanding modern titles at high settings.

The 8 GB VRAM is likely sufficient for Rust's textures at 1080p, but the core processing power is the limiting factor. The GPU's pixel rate of 42.88 GPixel/s is too low to handle 4K resolution effectively, as evidenced by the sub-30 FPS results at that resolution. The data shows that the RX 580 is a legacy component that significantly holds back the Intel Core Ultra 5 235 in this game. The CPU's high performance cannot compensate for the GPU's inability to render frames quickly enough, leading to the low combo rank observed.
