Rust

The Intel Core Ultra 5 235 and NVIDIA GeForce RTX 3080 pairing delivers a highly capable Rust experience, but the data reveals a system that shifts from being CPU-bound at lower resolutions to firmly GPU-bound at 4K. At 1080p, the combination produces exceptional frame rates that will satisfy competitive play, while at 4K, the RTX 3080 becomes the primary limiting factor, with average FPS falling below the 60 FPS threshold at higher presets. The benchmark results show a performance curve that is steep but predictable, with the CPU’s strong single-threaded performance providing a solid foundation at lower resolutions.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly illustrates the changing bottleneck as pixel count increases. At 1080p with High settings, the combo achieves 122 FPS, but this drops to 84 FPS at 1440p and further to 50 FPS at 4K. This represents a 59% performance loss from 1080p to 4K, which is a significant decline that points to the GPU being the limiting component at higher resolutions. The scaling pattern is consistent across all settings, with the gap between resolutions widening as pixel workload increases.

The Low settings preset provides the clearest view of the CPU’s capability. At 1080p Low, the system hits 216 FPS, a figure that suggests the CPU is able to feed the GPU efficiently without becoming a major constraint. At 1440p Low, the frame rate drops to 148 FPS, and at 4K Low, it falls to 88 FPS. The fact that the 4K Low result is still above 60 FPS indicates that the RTX 3080 retains enough headroom to handle the resolution when graphical complexity is reduced. However, the drop from 216 FPS at 1080p to 88 FPS at 4K Low shows that even with minimal graphical load, the GPU is still the primary factor in determining final output.

The Medium preset offers the most detailed data, as it is the only one with min and max FPS values recorded. At 1080p Medium, the average is 145 FPS with a range of 123 to 166 FPS. At 1440p Medium, the average is 100 FPS with a range of 85 to 115 FPS. At 4K Medium, the average drops to 59 FPS with a range of 50 to 68 FPS. This data shows that the frame time consistency degrades as resolution increases, with the spread between min and max FPS remaining relatively stable in percentage terms but the absolute values falling.

The Ultra preset produces the lowest frame rates across all resolutions. At 1080p Ultra, the average is 93 FPS, which is still smooth, but at 4K Ultra, the average plummets to 38 FPS, which is below the threshold for comfortable playability. The scaling from 1080p Ultra to 4K Ultra represents a 59% reduction in performance, mirroring the pattern seen at High settings. This consistency suggests that the RTX 3080’s memory bandwidth and compute capabilities are being saturated at 4K, regardless of the quality preset chosen.

How This Combo Ranks

In the benchmark database, this specific CPU-GPU combination ranks 731st out of 2953 tested combos for Rust. This places the pairing in the top 25% of all tested configurations, which is a strong result given the hardware involved. The ranking reflects the balance between the Intel Core Ultra 5 235 and the RTX 3080, with neither component being so weak that it severely hampers the other in this particular game.

The combo rank of 731 out of 2953 indicates that there are many systems that can outperform this one in Rust, but also a substantial number that fall behind. The CPU’s 89th percentile ranking among all CPUs suggests that the processor is not the limiting factor in most scenarios. The GPU’s 68th percentile ranking among all GPUs is lower, indicating that the RTX 3080 is a more mid-pack performer relative to the current market. This combination of a high-percentile CPU with a lower-percentile GPU results in a system that is well-balanced for Rust, where the game’s engine tends to favor strong single-threaded CPU performance.

The ranking data also implies that users with this combo are likely to see better results than those with a comparable GPU paired with a weaker CPU. The Core Ultra 5 235’s strong single-core benchmark scores, such as the 2085 in Cinebench R23 single-core, provide the kind of performance that Rust’s server-side and client-side processing can leverage. However, the RTX 3080’s 10 GB of VRAM and 760.3 GB/s of bandwidth may become a constraint in heavily modded or populated servers, which could affect the overall ranking in real-world scenarios.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in determining frame rates at higher resolutions. The GPU’s 10 GB of GDDR6X memory operates at 1188 MHz with an effective speed of 19 Gbps, providing 760.3 GB/s of bandwidth. This memory configuration is sufficient for Rust at 1080p and 1440p, but the 4K results suggest that the memory capacity and bandwidth are being pushed to their limits. At 4K Ultra, the average frame rate of 38 FPS indicates that the GPU is unable to maintain smooth performance under maximum load.

The GPU’s clock speeds are set at a base of 1440 MHz and a boost of 1710 MHz. These clocks, combined with 8704 shading units and 272 texture mapping units, deliver a theoretical FP32 performance of 29.77 TFLOPS. This compute capability is sufficient for Rust’s rendering requirements at 1080p and 1440p, but the 4K results show that the GPU is overwhelmed when rendering at that resolution with high-quality settings. The pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are solid figures, but they are not enough to prevent the frame rate from dipping below 60 FPS at 4K Medium.

The RTX 3080’s performance in Rust is heavily influenced by the game’s graphical demands. The data shows that the GPU scales predictably with resolution and settings, with the 4K Medium result of 59 FPS being the closest to the 60 FPS threshold. The GPU’s 68th percentile ranking among all GPUs suggests that while it is not a top-tier card in the current market, it remains a capable performer for this game. The 10 GB VRAM capacity is a potential concern for future-proofing, but for current Rust content, it does not appear to be a major bottleneck at 1080p or 1440p.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system’s performance across all resolution and settings combinations. At 1920x1080, the system produces the highest frame rates, with Low settings averaging 216 FPS, Medium averaging 145 FPS, High averaging 122 FPS, and Ultra averaging 93 FPS. The Medium preset at 1080p has a recorded minimum of 123 FPS and maximum of 166 FPS, showing a 43 FPS range.

Moving to 2560x1440, the frame rates remain strong but show a clear step down from 1080p. Low settings average 148 FPS, Medium averages 100 FPS with a range of 85 to 115 FPS, High averages 84 FPS, and Ultra averages 64 FPS. The 1440p Medium result is particularly notable, as it maintains an average above 100 FPS, which is excellent for a game like Rust that can be demanding on both CPU and GPU.

At 3840x2160, the system’s performance drops significantly, reflecting the increased pixel workload. Low settings average 88 FPS, Medium averages 59 FPS with a range of 50 to 68 FPS, High averages 50 FPS, and Ultra averages 38 FPS. The 4K Medium result is the only one at this resolution that comes close to the 60 FPS target, while the Ultra preset produces a frame rate that is below the threshold for smooth gameplay.

The data reveals that the system is capable of delivering playable frame rates at all resolution and settings combinations, with the exception of 4K Ultra, which falls below 40 FPS. The scaling from Low to Ultra settings at each resolution is consistent, with approximately a 50-60% performance drop from the lowest to highest quality presets. This consistency indicates that the game’s graphical settings have a proportional impact on the GPU’s workload.

CPU Role

The Intel Core Ultra 5 235 plays a crucial role in Rust’s performance, particularly at lower resolutions where the GPU is less stressed. The CPU features 14 cores and 14 threads, which is an unconventional configuration that lacks Hyper-Threading. This design choice means that the CPU relies on its physical cores for processing, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The high boost clock is a key factor in the CPU’s strong single-threaded performance, which is essential for Rust’s game logic and physics calculations.

The CPU’s benchmark results show a clear strength in single-threaded workloads. In Cinebench R23, the single-core score is 2085, while the multi-core score is 14769. This represents a multi-core to single-core ratio of approximately 7.1x, which is reasonable for a 14-core processor. The PassMark single-thread score of 4516 further reinforces the CPU’s single-threaded capability. These scores indicate that the CPU can handle the demands of Rust’s simulation and server communication without becoming a bottleneck.

The CPU’s cache configuration includes a 192 KB L1 cache per core, a 3 MB L2 cache per core, and a 24 MB shared L3 cache. This cache hierarchy is designed to provide low-latency access to frequently used data, which is important for a game like Rust that involves complex world state management. The 24 MB L3 cache is shared across all cores, allowing for efficient data sharing between cores that handle different aspects of the game simulation.

The CPU’s 89th percentile ranking among all CPUs indicates that it performs better than the vast majority of processors on the market. This is reflected in the measured FPS data, where the system achieves over 200 FPS at 1080p Low settings, suggesting that the CPU is not limiting the GPU’s output. The CPU’s performance is further validated by its nearest rivals, which include the AMD Ryzen AI 9 HX 375 and Intel Core i9-13900HX, both of which have nearly identical average benchmark scores within 0.1% of the Core Ultra 5 235.

The CPU’s power profile is also notable, with a 65W TDP that is managed through the Intel Socket 1851 platform. This power efficiency allows the CPU to maintain high boost clocks without excessive thermal output, which can be beneficial in smaller form factor builds. The CPU’s support for DDR5 memory with a dual-channel configuration and 102.4 GB/s of bandwidth ensures that memory bandwidth is not a constraint for the game’s data streaming requirements.
