Rust

The Intel Core Ultra 5 245 paired with the AMD Radeon RX 570 occupies a very specific, low-performance tier within the Rust benchmark database. With a combo rank of 2822 out of 2953 tested combinations, this system sits in the bottom 5% of all recorded results for the game. This placement indicates a fundamental mismatch between the hardware's potential and the demands of Rust, placing it firmly in the category of a legacy or entry-level setup for this title. The data suggests that while the CPU is a modern, capable processor, the GPU acts as a severe bottleneck, dragging the overall experience down to a level where only the lowest settings at 1080p provide a playable frame rate.

How This Combo Ranks

The ranking data for this specific CPU and GPU pairing in Rust is stark. Out of a total of 2953 tested combos, this configuration ranks at position 2822. This places it in the bottom percentile of systems, indicating that the vast majority of other hardware pairings deliver superior performance in this game. The rank is not a reflection of a single component's quality but rather the result of their combined output, and in this case, the synergy is poor for Rust's specific requirements.

The bottleneck is immediately apparent when examining the individual component benchmarks. The Intel Core Ultra 5 245 is a high-performing CPU, sitting in the 90th percentile when compared to all other CPUs in the database. Its average benchmark score of 48995 puts it in close competition with processors like the AMD Ryzen 9 7900, which scores 49228, a negligible 0.5% difference. This shows the CPU is not the limiting factor in this pairing. Conversely, the AMD Radeon RX 570, while not a slouch in the broader GPU landscape with a 74th percentile ranking, is a much older architecture. Its average benchmark score of 28766 is nearly identical to that of the NVIDIA Quadro RTX 8000, which is just 1.2% slower, and the AMD Radeon RX 470, which is 0.8% faster. However, the combination of a modern, high-end CPU with an older, mid-range GPU results in the bottom-tier ranking observed, highlighting the GPU's dominant role in determining Rust's performance.

GPU Role

The AMD Radeon RX 570 is the decisive component in this combo's performance, acting as the primary constraint. Its specifications, while respectable for its 2017 release, are not suited for a demanding, modern survival game like Rust. The GPU features 4 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 224.0 GB/s. This memory configuration is a critical limitation, as Rust is known for its high memory usage, often exceeding 4 GB at higher resolutions and settings, which can lead to texture thrashing and significant frame rate drops.

The GPU's clock speeds are set at a base of 1168 MHz and a boost of 1244 MHz. These clocks, combined with 2048 shading units, allow for a theoretical FP32 performance of 5.095 TFLOPS. While this is a reasonable compute figure for its generation, the architectural age and limited VRAM are likely the primary reasons for its poor performance in this game. The data shows that even at 1080p with Low settings, the average FPS is 66, which is playable but not exceptional. As settings and resolution increase, the GPU's limitations become more pronounced, with the average FPS plummeting to 15 at 4K High settings. The benchmark results clearly indicate that the RX 570 is overpowered by Rust's demands, making the CPU's potential largely irrelevant.

Resolution Scaling

The measured FPS data reveals a sharp performance decline as resolution increases, a classic sign of a GPU-bound scenario. At 1080p, the system achieves its best results, but these are still modest. Moving from 1080p to 1440p results in a significant drop in average FPS across all settings. For instance, on High settings, the average FPS falls from 38 at 1080p to 26 at 1440p, a reduction of roughly 32%. Scaling up to 4K from 1440p causes an even more drastic collapse, with the average FPS on High settings falling from 26 to 15, a 42% decrease.

This scaling pattern is a clear indicator that the GPU is the limiting component. A system where the CPU was the bottleneck would show less variation in FPS across resolutions, as the CPU's workload remains relatively constant. The dramatic FPS drops with each resolution increase demonstrate that the RX 570's rendering capabilities are being saturated. The rendering resolution is the primary factor determining performance here, not the CPU's processing power. The data suggests that even at 1080p, the GPU is working near its limits, and any increase in pixel count pushes it further into performance degradation.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across different resolutions and settings. At 1920x1080, the system is most capable. With Low settings, it achieves an average of 66 FPS, which is the highest average recorded for this combo. Medium settings see this drop to 44 FPS, with a minimum of 38 and a maximum of 51 FPS. High settings yield an average of 38 FPS, while Ultra settings bring the average down to 29 FPS.

Moving to 2560x1440, the performance takes a significant hit. The Low preset produces an average of 46 FPS, which is a 30% decrease from the 1080p Low result. Medium settings average 31 FPS, with a range of 26 to 35 FPS. High settings drop to an average of 26 FPS, and Ultra settings are barely playable at an average of 20 FPS. At 3840x2160, the combo struggles considerably. The Low preset is the only one that approaches a playable frame rate, averaging 27 FPS. Medium settings average just 18 FPS, High settings 15 FPS, and Ultra settings drop to a mere 12 FPS. These numbers chart a clear path of degradation, with the system only capable of providing a consistently smooth experience at 1080p on Low settings.

Settings Recommendations

Based on the measured FPS data, the only configuration that provides a consistently playable experience is the 1920x1080 resolution with the Low settings preset. This setting yields an average of 66 FPS, which is above the generally accepted threshold for smooth gameplay in a first-person survival game. While the visual quality will be reduced, the performance is adequate for a responsive and competitive experience. All other settings presets at this resolution, while playable, offer a less stable performance, with Medium averaging 44 FPS and High at 38 FPS.

For users who prioritize visual fidelity over raw frame rate, the 1080p Medium preset might be considered as a compromise, as it averages 44 FPS. However, the data suggests that the jump to High and Ultra settings provides diminishing returns for the significant FPS cost. At 1440p, even the Low preset, with an average of 46 FPS, may struggle to maintain smoothness during intense moments. The 4K resolution should be avoided entirely, as even the Low preset fails to hit 30 FPS. The data strongly recommends 1080p Low as the primary target, with 1080p Medium as a secondary option for those with a higher tolerance for occasional frame rate dips.

CPU Role

The Intel Core Ultra 5 245 is a powerful processor that is significantly underutilized in this configuration. Its specs are robust, featuring 14 cores and 14 threads based on the Arrow Lake architecture. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz. Its performance in synthetic benchmarks is impressive; for example, it scores 32924 in Cinebench R23 multicore and 4648 in single-core tests. This places it in the 90th percentile of all CPUs, indicating it is a top-tier performer for productivity and gaming alike.

Given the GPU's limitations, the CPU's role in Rust is to feed the graphics card with data. In this pairing, the CPU is clearly capable of doing so, as evidenced by the fact that frame rates drop dramatically with resolution increases, a phenomenon tied to the GPU's rendering load. If the CPU were the bottleneck, the frame rates would be more consistent across resolutions. The data implies that the Core Ultra 5 245 has significant headroom and is not being pushed to its limits. For example, its Passmark multithread score is 38706, far higher than what would be needed to support the RX 570's output. The bottleneck is unequivocally the GPU, meaning the CPU is waiting for the graphics card to finish its work, resulting in the low frame rates observed.
