Rust

The AMD Ryzen 7 5700 pairs an 8-core, 16-thread Zen 3 design with a 3.70 GHz base and 4.60 GHz boost clock. This is a desktop part on the AM4 socket built on a 7 nm TSMC process, and its 65 W TDP reflects a power-efficient design. For a game like Rust, the CPU’s thread count is significant because the title’s simulation and entity-tracking workloads scale with multiple cores. The benchmark data shows the CPU scores 6,617 points in 3DMark max-thread tests and 6,628 in the 16-thread run, indicating that multi-threaded performance is nearly saturated. In Cinebench R23, the multicore score is 20,655, while the single-core score is 2,916; this gap highlights that the chip has strong parallel throughput, but its single-thread performance is more modest, which can matter in Rust’s main-thread-heavy sections.

The CPU’s 16 MB of L3 cache and dual-channel DDR4 support with 51.2 GB/s bandwidth provide adequate feeding for the GPU in most scenarios. Compared to its nearest rivals, the Ryzen 7 5700 posts an average benchmark score of 27,220, placing it 0.7% ahead of the Intel Core i9-9900K and 0.8% ahead of the Intel Core i7-12700H. These deltas are small, meaning the 5700 is effectively in the same performance class as those chips, which is important context for Rust: the game will not be CPU-bound in a way that separates these processors drastically. The CPU’s 84th percentile ranking among all CPUs further confirms it has ample headroom for most gaming workloads. However, the measured FPS data in Rust suggests that at higher resolutions, the GPU becomes the bottleneck, as the FPS drops are steep regardless of the CPU’s capabilities.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 7 5700’s 8 cores and 16 threads are well-suited for Rust’s background simulation, which includes procedural world generation, physics, and AI. The passmark multithread score of 24,303 and the 3DMark 16-thread score of 6,628 indicate that the CPU can handle concurrent tasks without stalling. Yet the game’s measured FPS does not scale linearly with CPU power; instead, the data shows that at 1080p Low settings, the average FPS is 76.2, which is the highest measured result. This suggests that at lower settings, the CPU is providing enough throughput to allow the GPU to work as fast as it can, but the GPU’s limits are quickly reached.

The single-thread score of 901 in 3DMark and 2,916 in Cinebench R23 is moderate, and Rust’s main thread often becomes a limiter when many entities are on screen. Still, the 0.7% delta over the Core i9-9900K indicates that the 5700 is not leaving performance on the table in single-threaded tasks. The data does not show a scenario where the CPU is the primary constraint, as even at 1080p Ultra (30.7 FPS) and 1440p Ultra (21.6 FPS), the FPS drops are more consistent with GPU limitations. The CPU’s 84th percentile ranking supports the notion that it is a capable partner for the RX 580, but it cannot compensate for the GPU’s raw pixel-pushing limits at higher settings.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is a Polaris 20 chip with 8 GB of GDDR5 memory on a 256-bit bus, providing 256.0 GB/s of bandwidth. Its base clock is 1257 MHz with a boost of 1340 MHz, and it has 2,304 shading units. The GPU’s 6.175 TFLOPS of FP32 compute is a modest figure by modern standards, and its 53rd percentile ranking among all GPUs places it in the mid-range. In Rust, the VRAM capacity is sufficient for the game’s textures, but the memory bandwidth and raw compute are the limiting factors at higher resolutions and settings. The data shows that at 4K Ultra, the average FPS is 13.3, which is barely playable, while at 1080p Low, it reaches 76.2 FPS.

The RX 580’s nearest rival, the NVIDIA GeForce GTX 570, has an identical average score (13,564 vs. 13,559, a 0% delta), which underscores that this GPU is an older architecture. The GTX 950 is 0.1% behind, and the AMD Radeon Pro 455 is 1.1% behind, showing that the RX 580 sits in a tight cluster of similarly performing cards. This means that in Rust, the FPS results are consistent with a GPU that is entry-level for modern titles. The GPU’s 8 GB VRAM is not a bottleneck at 1080p, but at 4K, the pixel fill rate of 42.88 GPixel/s is insufficient, as evidenced by the 16.9 FPS at 4K High. The GPU’s compute score of 3,488 in Passmark further indicates that it handles math-heavy tasks, but Rust’s rendering pipeline at high settings overwhelms it.

FAQ

Q: What is the best resolution to use with this combo in Rust?

A: The data shows the highest average FPS is 76.2 at 1920x1080 with Low settings. At 2560x1440, the best result is 48.9 FPS on Low, and at 3840x2160, it drops to 30.1 FPS on Low. Thus, 1080p is the only resolution where the combo exceeds 60 FPS average.

Q: How does the FPS drop when moving from 1080p to 1440p?

A: At Low settings, the average FPS goes from 76.2 at 1080p to 48.9 at 1440p, a drop of 27.3 FPS. At High settings, it goes from 43.2 to 26.7, a drop of 16.5 FPS. The percentage drop is larger at Low settings (about 36%) compared to High (about 38%).

Q: Is the CPU or GPU more responsible for the performance at 1080p Ultra?

A: At 1080p Ultra, the average FPS is 30.7. The CPU’s single-thread score of 2,916 in Cinebench R23 is not exceptionally high, but the GPU’s 53rd percentile ranking suggests it is the weaker component. The steep FPS drop from Low (76.2) to Ultra (30.7) at the same resolution indicates the GPU’s processing limits are the primary constraint.

Q: What is the highest playable setting at 1440p?

A: At 2560x1440, the Low preset yields 48.9 FPS, Medium yields 35.8 FPS, High yields 26.7 FPS, and Ultra yields 21.6 FPS. None of these reach 60 FPS, so the best option for smoother gameplay is Low, while Medium is acceptable for a more balanced visual experience.

Q: How does the RX 580 compare to its closest rival in terms of benchmark scores?

A: The RX 580 has an average benchmark score of 13,559, which is exactly the same as the NVIDIA GeForce GTX 570 (13,564, 0% delta). It is 0.1% ahead of the GTX 950 and 1.1% ahead of the AMD Radeon Pro 455, indicating these GPUs perform nearly identically in synthetic tests.

Q: Does the CPU’s performance advantage over its rivals translate to higher FPS in Rust?

A: The Ryzen 7 5700 is 0.7% faster than the Intel Core i9-9900K in average benchmark score, but the measured FPS in Rust does not show this delta. The FPS is more dependent on the GPU, as evidenced by the consistent drops across settings, so the CPU’s small lead does not produce a noticeable FPS advantage.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured results show a clear progression: Low settings achieve 76.2 FPS average, Medium drops to 51.9 FPS, High falls to 43.2 FPS, and Ultra bottoms out at 30.7 FPS. This is the only resolution where the Low preset crosses the 60 FPS threshold, making it the most viable for competitive play. The gap between Medium and High is 8.7 FPS, while the gap between High and Ultra is 12.5 FPS, indicating that the Ultra preset imposes a heavy cost.

Moving to 2560x1440, the FPS numbers halve in some cases: Low yields 48.9 FPS, Medium 35.8 FPS, High 26.7 FPS, and Ultra 21.6 FPS. The drop from 1080p Low to 1440p Low is 27.3 FPS, which is a 36% reduction. At 1440p, even Low settings fall below 60 FPS, so users must accept lower frame rates or reduce the resolution. The Ultra preset at 1440p (21.6 FPS) is only slightly higher than the 4K Low result (30.1 FPS), showing how resolution scaling affects the GPU.

At 3840x2160, the FPS is critically low across all settings: Low is 30.1 FPS, Medium is 20.6 FPS, High is 16.9 FPS, and Ultra is 13.3 FPS. This resolution is not playable for any setting above Low, and even Low is borderline, as it averages below 30 FPS. The data shows that the RX 580’s 256-bit bus and 6.175 TFLOPS cannot keep up with 4K pixel counts, regardless of the CPU’s capabilities.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K reveals a GPU-bound system. At Low settings, the average FPS drops from 76.2 at 1080p to 48.9 at 1440p (a 36% decrease) and then to 30.1 at 4K (a 60% decrease from 1080p). At High settings, the numbers are 43.2 (1080p), 26.7 (1440p), and 16.9 (4K), showing a similar proportional decline. If the CPU were the bottleneck, the FPS would remain more constant as resolution increases, because the CPU workload does not change with pixels. Instead, the FPS falls steadily, which is a classic sign of pixel-throughput limitation.

The 4K Ultra result of 13.3 FPS is 6.4 times lower than the 1080p Low result, further emphasizing the GPU’s inability to handle high pixel densities. The RX 580’s pixel rate of 42.88 GPixel/s is the key metric here; at 4K, the GPU must fill over 8 million pixels per frame, and the data shows it cannot do so at acceptable speeds. The CPU’s 84th percentile ranking and high multi-thread scores do not rescue these results, confirming that the RX 580 is the limiting component in Rust at higher resolutions. At 1080p, the CPU has more influence, but the GPU still sets the ceiling, as the Ultra preset (30.7 FPS) is far below the CPU’s potential frame output.

Settings Recommendations — which preset gives the best experience per the measured rows

For users prioritizing frame rate, the 1080p Low preset is the only measured configuration that averages above 60 FPS, at 76.2 FPS. This is the best choice for a responsive experience in Rust’s PvP and building scenarios. At 1080p Medium, the 51.9 FPS average is still playable but falls short of the smoothness threshold; it offers a moderate visual upgrade over Low without halving the frame rate. The 1080p High preset (43.2 FPS) is a compromise for those who want better textures, but the drop to 30.7 FPS at Ultra is not justified by the visual gains, as the game becomes noticeably less fluid.

At 1440p, the Low preset (48.9 FPS) is the most playable option, though it will feel less smooth than 1080p. The Medium preset (35.8 FPS) is acceptable for slower-paced gameplay, but High (26.7 FPS) and Ultra (21.6 FPS) are too choppy for general use. The data suggests that 1440p is only viable with Low settings, and even then, the frame rate is below 60 FPS. At 4K, no setting is recommended for gameplay, as the highest average is 30.1 FPS on Low, which is barely playable and will stutter in action scenes. The best experience per the measured rows is 1080p Low for maximum smoothness, or 1080p Medium for a balanced approach, given the GPU’s limitations.
