Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 570 ranks 1638th out of 1717 tested combinations in Rust, placing this system in the bottom 5% of all tested hardware pairings. This is a low position, and the measured frame rates confirm that this combo struggles to deliver a fluid experience at most settings. The data shows a system that is heavily constrained, with performance that falls off sharply as resolution and visual fidelity increase.

How This Combo Ranks

The combo rank of 1638 out of 1717 is a decisive statement about this pairing's capabilities in Rust. The Intel Core i5-12400 itself is a strong processor, performing at the 77th percentile compared to all CPUs, with an average benchmark score of 19850. However, the AMD Radeon RX 570, while sitting at the 74th percentile among all GPUs with an average score of 30158, is not sufficient for this demanding title. The combination of a capable CPU and an aging GPU results in a system that is bottlenecked by the graphics card in nearly every scenario. The data indicates that the GPU is the primary limiting factor, as the CPU's potential is left untapped, with the system unable to maintain playable frame rates at higher settings. This rank is not a reflection of a balanced system, but rather one where the graphics processor holds back the entire experience.

GPU Role

The AMD Radeon RX 570 is the clear bottleneck in this configuration. With 4 GB of GDDR5 memory on a 256-bit bus, it provides a memory bandwidth of 224.0 GB/s. The card operates at a base clock of 1168 MHz and a boost clock of 1244 MHz. These specifications, while respectable for the Polaris 20 chip's era, are insufficient for Rust's demands. The measured FPS data shows a severe drop when moving from 1080p to 4K. At 1080p Low, the system achieves 63.4 FPS, but at 4K Low, it falls to 29.4 FPS. This steep decline highlights the GPU's limited pixel throughput and memory capacity. Furthermore, the GPU's FP32 performance of 5.095 TFLOPS is not enough to handle the game's complex rendering at higher resolutions. The data suggests that the RX 570 is only capable of providing a smooth experience at the lowest settings and resolution, and its performance degrades rapidly with any increase in graphical load.

CPU Role

The Intel Core i5-12400 is a modern 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its 18 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a well-rounded component. In synthetic benchmarks, it achieves a Cinebench R23 multi-core score of 15935 and a single-core score of 2249. These numbers show that the CPU has ample processing power. However, the measured game FPS does not reflect this strength. For instance, at 1080p Low, the system hits 63.4 FPS, which is a reasonable frame rate, but at 1080p Ultra, it plummets to 26.5 FPS. This disparity is not caused by the CPU but rather by the GPU's inability to keep up with the increased rendering work. The CPU's role is to feed the GPU with data, and in this pairing, it is doing its part effectively. The data indicates that the i5-12400 is not the limiting factor; it is waiting on the RX 570 to finish its work.

FAQ

Q: Is this CPU-GPU combo capable of running Rust at 60 FPS?

A: The measured data shows that the combo only achieves 63.4 FPS at 1080p with Low settings. At any other setting or resolution, the average FPS falls below 46.1, indicating that a consistent 60 FPS experience is only possible at the lowest graphical preset.

Q: How does the RX 570 compare to its closest rivals in terms of raw performance?

A: The RX 570 has an average benchmark score of 30158. Its nearest rival, the NVIDIA GeForce RTX 5060, has an average score of 30109, which is 0.2% lower. The AMD Radeon RX 7700 XT scores 30097, also 0.2% lower than the RX 570. These deltas are within a margin of error, showing that the RX 570 is performance-equivalent to these much newer cards in this specific benchmark metric.

Q: What is the best resolution to play Rust with this hardware?

A: According to the data, 1920x1080 is the only resolution where the system achieves playable frame rates. At 1080p with Low settings, it averages 63.4 FPS, but this drops to 40.8 FPS at High settings. Moving to 1440p reduces performance further, with the best average FPS being 46.1 at Low settings.

Q: Is the Intel Core i5-12400 a strong performer relative to other CPUs?

A: Yes, the i5-12400 is ranked at the 77th percentile among all CPUs. Its average benchmark score of 19850 is nearly identical to the Intel Core i7-9700, which scores 19831, a delta of only 0.1%. It also slightly outperforms the Intel Core i5-11600K, which scores 19771, by 0.4%.

Q: Does increasing the graphics settings from Low to Medium have a large impact on performance?

A: The impact is significant. At 1080p, the average FPS drops from 63.4 on Low to 44.6 on Medium, a decrease of 18.8 FPS. At 1440p, the drop is from 46.1 to 31.2 FPS. This shows that even a single step up in settings places a substantial load on the GPU.

Q: What does the GPU's percentile rank of 74 indicate?

A: It indicates that the AMD Radeon RX 570 performs better than 74% of all GPUs in the benchmark database. However, this relative strength does not translate to high performance in Rust, as the game's specific demands prove too much for the 4 GB of VRAM and the card's overall processing power.

Resolution Scaling

The FPS data reveals a clear and predictable pattern of performance degradation as resolution increases. At 1080p Low, the system manages 63.4 FPS. This is the only configuration that achieves a frame rate above 60. When resolution is increased to 1440p at the same Low settings, the average FPS drops to 46.1, a 27% reduction. At 4K Low, the average FPS plummets to 29.4, which is less than half of the 1080p performance. This trend is consistent across all settings. For example, at High settings, the FPS goes from 40.8 (1080p) to 25.2 (1440p) to 15.8 (4K). This pattern strongly indicates that the GPU is the limiting component. The CPU has more than enough headroom to handle the extra pixels, but the RX 570's rendering capabilities are quickly overwhelmed. The data suggests that the frame rate is directly tied to the number of pixels being processed, and the GPU's performance scales poorly with this increased load.

Settings Recommendations

Based on the measured rows, the only viable configuration for a smooth experience is 1920x1080 with Low settings, which produces an average of 63.4 FPS. This is the sole setting that breaches the 60 FPS threshold. If a user prefers higher visual fidelity, they can consider 1080p Medium, which yields 44.6 FPS, but this comes at a significant cost to smoothness. The jump to High settings at 1080p results in only 40.8 FPS, and Ultra is not recommended, as it falls to 26.5 FPS. At 1440p, even the Low preset only manages 46.1 FPS, which is playable but not ideal. The data clearly shows that any attempt to play at 4K will result in a sub-30 FPS experience, which is not acceptable for a fast-paced survival game. The best experience per the measured rows is unequivocally 1080p Low, as it is the only way to achieve a frame rate that approaches the 60 FPS target.
