The CPU’s higher percentile rank indicates it has more headroom relative to its peers, while the GPU’s lower rank aligns with the observed frame rate limitations.

Q: What are the measured minimum and maximum FPS values for this combo?

A: The dataset includes min and max FPS only for Medium settings. At 3840x2160 Medium, the range is 15 to 21 FPS. At 2560x1440 Medium, the range is 26 to 35 FPS. At 1920x1080 Medium, the range is 38 to 51 FPS. No min or max values are provided for other settings.

Settings Recommendations

The measured FPS data provides a clear picture of which settings preset offers the best experience for this hardware combination. The primary goal for any playable session in Rust is maintaining an average frame rate that avoids severe stutter, typically above 30 FPS. With that in mind, the data shows that Low settings at 1920x1080 is the only configuration that delivers a comfortable margin above this threshold, achieving an average of 66 FPS. This is the recommended preset for users prioritizing smoothness and responsiveness, as it provides the highest headroom for complex scenes with multiple players and structures.

At 2560x1440, Low settings produce an average of 46 FPS, which is also playable but with less margin. The jump to Medium at this resolution drops the average to 31 FPS, which is borderline and may result in noticeable hitches during intense gameplay. High settings at 2560x1440 yield 26 FPS, which is below the smoothness threshold and not recommended for competitive or fast-paced play. Ultra at this resolution falls to 20 FPS, making it unsuitable for anything other than static screenshots.

For 1080p, Medium settings at 44 FPS offer a balanced trade-off between visual quality and performance. This preset is a viable alternative to Low if the user is willing to accept a 33% reduction in average frame rate for improved textures and effects. However, High settings at 1080p drop to 38 FPS, which is still playable but begins to approach the lower bound of acceptable performance. Ultra at 1080p, with an average of 29 FPS, is not recommended for active gameplay. At 4K, no settings preset is recommended, as even Low only achieves 27 FPS, and Medium drops to 18 FPS. The data indicates that users should stick to 1080p Low or Medium for the best experience, with 1440p Low as a secondary option if resolution is prioritized over frame rate stability.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235 and AMD Radeon RX 570 ranks 2822 out of 2953 tested combos in Rust. This position places it in the bottom 4.4% of all configurations, highlighting a significant performance deficit relative to the majority of systems tested. The rank is driven primarily by the GPU’s limitations, as the CPU’s overall benchmark performance is considerably stronger relative to its peers. The GPU holds a percentile rank of 74 among all GPUs, while the CPU holds a percentile rank of 89 among all CPUs. This disparity suggests that the RX 570 is the limiting factor in this pairing, unable to fully utilize the CPU’s processing capabilities in Rust’s demanding environments.

When compared to the GPU’s nearest rivals, the RX 570’s average benchmark score of 28766 is nearly identical to that of the AMD Radeon RX 6800M, which scores 28874 with a deltaPct of -0.4. The AMD Radeon R9 M295X scores 28580 with a deltaPct of 0.7, and the NVIDIA Quadro RTX 8000 scores 28421 with a deltaPct of 1.2. These small deltas indicate that the RX 570’s raw compute performance is closely matched to these other cards, yet the in-game results in Rust are still constrained by its 4 GB VRAM and older GCN 4.0 architecture. The CPU’s nearest rivals, including the AMD Ryzen AI 9 HX 375 with a deltaPct of 0.1, the Intel Core i9-13900HX with a deltaPct of -0.1, and the AMD EPYC 4364P with a deltaPct of 0.2, all show that the Ultra 5 235’s average benchmark score of 46062 is on par with these other processors. This reinforces that the CPU is not the source of the low rank; rather, the GPU’s inability to maintain high frame rates in Rust drags the entire combo down.

The combo’s rank of 2822 indicates that users with this hardware will experience performance well below what is typical for modern gaming systems. In Rust, which is known for its heavy CPU load during server interactions and base building, this rank suggests that even with the CPU’s strong multi-threaded capabilities, the GPU’s limited pixel throughput and memory bandwidth prevent the system from achieving playable frame rates at higher settings. The data shows a clear trend: as resolution and settings increase, the frame rate drops sharply, confirming that the GPU is the primary bottleneck.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo performs across three resolutions and four settings presets. At 3840x2160, the results are uniformly poor. Low settings yield an average of 27 FPS, which is the highest at this resolution. Medium settings produce 18 FPS, with a minimum of 15 and a maximum of 21. High settings drop to 15 FPS, and Ultra falls to 12 FPS. None of these values are suitable for real-time gameplay, as even the lowest preset fails to reach 30 FPS. The gap between Low and Ultra at 4K is 15 FPS, representing a 55% reduction in performance.

At 2560x1440, the performance improves but remains limited. Low settings achieve an average of 46 FPS, which is the playable threshold for many users. Medium settings average 31 FPS, with a range of 26 to 35 FPS, indicating that frame times can spike during demanding scenes. High settings drop to 26 FPS, and Ultra falls to 20 FPS. The jump from Low to Medium at this resolution costs 15 FPS, a 33% decrease, while High to Ultra costs 6 FPS. This suggests that the GPU struggles to handle the increased shading and texture loads beyond Low settings.

At 1920x1080, the results are the most varied. Low settings deliver an average of 66 FPS, which is smooth and responsive. Medium settings average 44 FPS, with a minimum of 38 and a maximum of 51, providing a stable experience for most situations. High settings average 38 FPS, which is borderline but playable. Ultra settings drop to 29 FPS, which is below the smoothness threshold. The transition from Low to Medium at 1080p reduces the average by 22 FPS, a 33% drop. The transition from High to Ultra costs 9 FPS. The data shows that the RX 570 has enough headroom at 1080p Low to maintain a consistent frame rate, but any increase in quality settings quickly overwhelms its capabilities.

Across all resolutions, the pattern is consistent: the GPU’s performance scales poorly with increased graphical demands. The difference between Low and Ultra settings is more pronounced at lower resolutions, where the CPU has more bandwidth to feed the GPU, yet the GPU still cannot keep up. The min and max FPS data for Medium settings reveals that frame pacing is inconsistent, with the spread between minimum and maximum ranging from 6 FPS at 4K to 13 FPS at 1080p. This inconsistency indicates that the GPU’s frame buffer and memory bandwidth are insufficient for Rust’s dynamic environments.

GPU Role

The AMD Radeon RX 570 is built on the Polaris 20 chip using the GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It features 2048 shading units, 128 texture mapping units, and 32 render output units. The GPU operates at a base clock of 1168 MHz and a boost clock of 1244 MHz, with memory clocked at 1750 MHz (7 Gbps effective). The 4 GB of GDDR5 memory is accessed via a 256-bit bus, providing a bandwidth of 224.0 GB/s. This memory configuration is a critical limitation in Rust, as the game’s large maps and numerous assets can easily exceed 4 GB of VRAM at higher settings. The data shows that at 4K Ultra, the average FPS drops to 12, which is likely due to the GPU running out of memory and resorting to system memory, causing severe stutter.

The GPU’s compute capabilities are reflected in its benchmark scores. In 3DMark Steel Nomad DX12, it scores 880. In Geekbench, it scores 39349 in Metal, 32084 in OpenCL, and 42752 in Vulkan. These scores place the RX 570 at the 74th percentile among all GPUs, indicating that it is a mid-range performer from its generation. Its average benchmark score of 28766 is nearly identical to that of the AMD Radeon RX 6800M (28874) and the AMD Radeon R9 M295X (28580), showing that its raw compute performance is competitive with those parts. However, in Rust, the RX 570’s age and lack of modern features like hardware ray tracing or larger VRAM pools become apparent. The GPU’s pixel rate is 39.81 GPixel/s and texture rate is 159.2 GTexel/s, which are sufficient for lower resolutions but insufficient for 4K.

The GPU’s TDP is 150 W, with a suggested PSU of 450 W, and it requires a single 6-pin power connector. Its dual-slot design and 241 mm length are typical for its era. The RX 570 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, which are all compatible with Rust. The data indicates that the GPU’s 4 GB VRAM is its most significant bottleneck. At 1080p Medium, the average FPS is 44, but the min FPS of 38 suggests that scenes with many players or complex structures cause memory pressure. At 1440p, the GPU’s bandwidth of 224.0 GB/s becomes insufficient, leading to average frame rates below 46 FPS. At 4K, the GPU is entirely overwhelmed, with all settings failing to reach 30 FPS. The GPU’s end-of-life production status and its release in 2017 highlight its age relative to modern titles like Rust.

CPU Role

The Intel Core Ultra 5 235 is a desktop processor from the Core Ultra Series 2, based on the Arrow Lake architecture and manufactured on a 3 nm process at TSMC. It features 14 cores and 14 threads, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The CPU’s cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. It supports DDR5 memory with a dual-channel interface and a maximum bandwidth of 102.4 GB/s. The CPU has a TDP of 65 W and uses the Intel Socket 1851. Its integrated graphics are Arc Xe-LPG Graphics 24EU, though they are not used for gaming in this configuration.

The CPU’s benchmark performance is strong. In Cinebench R23, it scores 14769 in multicore and 2085 in singlecore. In Cinebench R20, it scores 6202 in multicore and 875 in singlecore. Passmark results show a multithread score of 37816, a single-thread score of 4516, and a physics score of 2570. The CPU’s average benchmark score is 46062, placing it at the 89th percentile among all CPUs. This is significantly higher than the GPU’s 74th percentile, indicating that the CPU has more relative processing power than the GPU. The CPU’s nearest rivals, including the AMD Ryzen AI 9 HX 375 (46030), Intel Core i9-13900HX (46098), and AMD EPYC 4364P (45970), all have nearly identical average scores, confirming that the Ultra 5 235 is a high-performance part.

In Rust, the CPU’s role is to manage game logic, physics, and server communication. The data shows that the CPU is not the bottleneck in this combo, as frame rates drop more sharply with increased resolution and settings, which primarily affect the GPU. For instance, at 1080p Low, the average FPS is 66, which is likely near the CPU’s maximum frame delivery capability. When the GPU is tasked with higher settings, the average FPS drops to 38 at High and 29 at Ultra, indicating that the GPU is unable to keep up with the CPU’s output. The CPU’s high boost clock of 5.00 GHz and 14 cores provide ample single-thread and multi-thread performance for Rust’s demanding simulation. The L3 cache of 24 MB helps reduce memory latency, which is beneficial for the game’s frequent entity updates.

The CPU’s memory bandwidth of 102.4 GB/s is shared with the GPU via the PCIe Gen 5 interface, though the RX 570 uses PCIe 3.0 x16, which limits data transfer speeds. This mismatch does not appear to be a major issue, as the GPU’s own memory bandwidth is the limiting factor. The CPU’s process node of 3 nm and transistor count of 17,800 million give it a significant efficiency advantage over the GPU’s 14 nm process. The CPU’s release date of January 2025 makes it much newer than the GPU’s 2017 release, further emphasizing the generational gap between the two components. The data suggests that upgrading the GPU would yield substantial performance gains in Rust, while the CPU has enough headroom to support a more powerful graphics card without becoming a bottleneck.
