Rust

The Intel Core i5-11400F and AMD Radeon RX 570 represent a pairing of two end-of-life components that still see widespread use. In Rust, the data shows a combination that is heavily constrained by the GPU at higher resolutions, while the CPU’s six cores and twelve threads provide a baseline capable of pushing playable frame rates at 1080p. The measured results place this combo at rank 1634 out of 1717 tested combinations, indicating it sits in the lower quartile of performance for this title.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, built on Intel’s 14 nm process. It operates with a base clock of 2.60 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The CPU’s cache layout includes 80 KB of L1 per core, 512 KB of L2 per core, and a shared 12 MB L3 cache. Memory support is limited to dual-channel DDR4 with a theoretical bandwidth of 51.2 GB/s.

In Rust, a game that relies heavily on world simulation and entity updates, the CPU’s single-thread performance is often the deciding factor for minimum frame rates. The i5-11400F posts a 3dmark single-thread score of 868 and a passmark_single_thread score of 2981. Its multi-threaded capabilities are reflected in a cinebench_r23_multicore score of 14372 and a geekbench_multicore score of 7579. These numbers place the CPU at the 75th percentile among all processors, with an average benchmark score of 17181.

Comparing the i5-11400F to its nearest rivals in the database, the data shows a tight cluster. The AMD Ryzen 7 5700U scores 17189, a delta of 0%, while the Intel Core i7-1260P scores 17212, a delta of -0.2%. The Intel Core Ultra 7 164U also scores 17215, a -0.2% delta, and the Intel Core i5-1240U scores 17141, a 0.2% delta. This indicates that the i5-11400F’s processing power is effectively identical to these other chips in aggregate benchmarks, despite differences in architecture and core counts.

Given that the measured frame rates at 1080p Low reach 66.7 FPS, it is clear the CPU can feed the GPU adequately at lower settings. However, at 4K Ultra, the average FPS drops to 11.0, which is far below any playable threshold. The CPU’s role in this combo is to provide a stable baseline; the data suggests that at 1080p, the processor is not the primary bottleneck, as the frame rate scales significantly with GPU load.

GPU Role

The AMD Radeon RX 570 is a Polaris 20 chip built on the GCN 4.0 architecture, manufactured on a 14 nm process by GlobalFoundries. It features 4 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 224.0 GB/s. 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 card has 2048 shading units, 128 texture mapping units, and 32 ROPs, delivering a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. FP32 performance is rated at 5.095 TFLOPS.

The GPU’s benchmark scores include a 3dmark_steel_nomad_dx12 score of 880, a geekbench_opencl score of 32084, and a geekbench_vulkan score of 42752. Its average benchmark score is 30158, placing it at the 74th percentile of all GPUs. Interestingly, the nearest rivals listed in the data are far more modern and powerful cards, including the NVIDIA GeForce RTX 5060 (score 30109, delta 0.2%), AMD Radeon RX 7700 XT (score 30097, delta 0.2%), NVIDIA Tesla M60 (score 29969, delta 0.6%), and NVIDIA GeForce RTX 5070 Mobile (score 29928, delta 0.8%). This suggests that the RX 570’s aggregate score places it in a strange bracket, but its actual gaming performance in Rust is clearly limited by its VRAM and raw compute.

The measured FPS data shows a stark scaling pattern. At 1920x1080, the RX 570 delivers 66.7 FPS on Low, 43.6 FPS on Medium, 39.5 FPS on High, and 31.9 FPS on Ultra. At 2560x1440, the scores fall to 46.1 FPS (Low), 28.9 FPS (Medium), 29.1 FPS (High), and 20.7 FPS (Ultra). At 3840x2160, the card is overwhelmed: 28.6 FPS on Low, 15.5 FPS on Medium, 12.8 FPS on High, and 11.0 FPS on Ultra. The 4 GB VRAM buffer is a critical limitation, as Rust’s asset streaming and texture loading can easily exceed this capacity at higher resolutions, causing severe frame rate degradation.

FAQ

Q: What is the best resolution for this combo to maintain a playable frame rate?

A: The data shows that 1920x1080 is the only resolution where the combo achieves a consistently playable average FPS. At 1080p Low, it hits 66.7 FPS, and even at High, it manages 39.5 FPS. At 1440p, the highest average is 46.1 FPS on Low, which is borderline, while 4K is not viable, with the best average being 28.6 FPS on Low.

Q: How does the CPU compare to its closest competitors in raw processing power?

A: The i5-11400F’s average benchmark score is 17181. Its nearest rival, the AMD Ryzen 7 5700U, scores 17189, a 0% delta. The Intel Core i7-1260P scores 17212 (-0.2%), and the Intel Core Ultra 7 164U scores 17215 (-0.2%). The Intel Core i5-1240U is slightly behind at 17141, a 0.2% delta. This means the i5-11400F is statistically tied with these processors.

Q: Is the GPU or the CPU the limiting factor in Rust?

A: The measured FPS data indicates the GPU is the primary bottleneck, especially at higher resolutions. At 1080p, the frame rate varies significantly with graphics settings (from 66.7 FPS on Low to 31.9 FPS on Ultra), which points to GPU load. The CPU’s 75th percentile ranking and strong multi-threaded scores suggest it is less of a constraint than the RX 570’s 4 GB VRAM and compute limits.

Q: What is the frame rate difference between Low and Ultra settings at 1080p?

A: At 1920x1080, the Low preset yields an average of 66.7 FPS, while the Ultra preset yields 31.9 FPS. This represents a drop of 34.8 FPS, or roughly 52%, when moving from the lowest to the highest quality settings.

Q: Does the combo’s rank in the database reflect its real-world usability?

A: The combo is ranked 1634 out of 1717 tested combinations, placing it in the bottom 5% of all tested hardware pairings for Rust. This low rank is consistent with the measured data, which shows that the system cannot handle high resolutions or ultra settings, though it remains functional at 1080p with lower presets.

Q: What is the GPU’s memory bandwidth and how does it affect performance?

A: The RX 570 has a 256-bit memory bus with a bandwidth of 224.0 GB/s. In Rust, this bandwidth is sufficient for 1080p, but at 1440p and 4K, the combination of limited bandwidth and 4 GB VRAM causes significant frame rate drops, as seen in the data where 4K Ultra falls to 11.0 FPS.

Settings Recommendations

The measured data provides a clear hierarchy of performance across resolutions and presets. For a playable experience, the 1920x1080 resolution is the only option that delivers consistent frame rates above 30 FPS across all settings. The Low preset at 1080p offers the highest average FPS at 66.7, which is ideal for competitive play or maximum smoothness. The Medium preset drops to 43.6 FPS, still playable, while High yields 39.5 FPS, and Ultra falls to 31.9 FPS.

Given the GPU’s limitations, the best experience is achieved at 1080p with the Medium preset. This setting balances visual fidelity with performance, providing a 43.6 FPS average, which is above the 30 FPS threshold for acceptable playability. The High preset at 39.5 FPS is also viable, but the jump to Ultra offers a marginal visual improvement for a significant performance cost. At 1440p, only the Low preset (46.1 FPS) is recommended; Medium (28.9 FPS) and High (29.1 FPS) are borderline, and Ultra (20.7 FPS) is not recommended. At 4K, all presets deliver unplayable frame rates, with the highest being 28.6 FPS on Low.

The data suggests that users should prioritize resolution over settings. A 1080p Medium preset provides a smoother experience than a 1440p Low preset, despite the latter having a higher average FPS (46.1 vs 43.6), because the former offers better visual quality with a minimal performance penalty. For users with a 1440p monitor, the Low preset is the only option that keeps the game playable, but the frame rate is not stable enough for competitive scenarios.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of the Intel Core i5-11400F and AMD Radeon RX 570 holds the rank of 1634 out of 1717 total combinations. This position places it in the bottom 5% of all tested systems, confirming that it is a low-end configuration for this title. The rank is consistent with the measured FPS data, which shows that the combo struggles to maintain playable frame rates at resolutions above 1080p.

The GPU’s percentile ranking of 74th among all GPUs is misleading in this context. While its average benchmark score of 30158 is close to that of far newer cards like the RTX 5060 (30109) and RX 7700 XT (30097), the RX 570’s actual gaming performance in Rust is severely hampered by its 4 GB VRAM and older architecture. The CPU’s 75th percentile ranking is more representative of its capability, as it performs on par with several modern mobile processors.

The combo’s rank reflects a fundamental mismatch for Rust’s demands. The game’s high CPU overhead for world simulation is handled adequately by the i5-11400F, but the RX 570’s memory and compute limitations become the dominant factor at higher settings. The result is a system that is only suitable for 1080p gaming with reduced quality settings. For any user expecting to run Rust at higher resolutions or with the Ultra preset, the data shows this combo will fall short of a smooth experience. The 1634th rank serves as a clear indicator that this pairing is not designed for high-end Rust play, but rather for basic, playable frame rates at lower graphical fidelity.
