Rust

The Intel Core i7-13700K paired with the AMD Radeon RX 570 presents a classic case of CPU overkill meeting GPU bottleneck. The benchmark data for Rust shows a system where the processor has far more headroom than the graphics card can use, particularly at higher resolutions. This analysis examines the measured performance metrics to determine the best settings, the role of the CPU, and how this combination ranks among tested systems.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combination in Rust depends heavily on the target resolution. The data clearly shows that the AMD Radeon RX 570 is the primary limiting factor, and settings adjustments yield substantial gains.

At 1920x1080, the lowest preset delivers a usable 66 average FPS, which is the only preset to cross the 60 FPS threshold. The Medium preset produces 44 average FPS, while High drops to 38 average FPS. Ultra is the least viable, with an average of 29 frames per second. For most players on a 1080p display, the Low preset is the only practical choice for smooth gameplay, as the difference between 66 and 44 average FPS is significant.

At 2560x1440, the pattern shifts. The Low preset remains the best option with 46 average FPS, but the gap to Medium narrows, with Medium delivering 31 average FPS. High provides 26 average FPS, and Ultra falls to 20 average FPS. The measured minimum for Medium at this resolution is 26 FPS, which is below the 46 average of Low. Given that the minimum frame times matter in a survival game where quick reactions are required, the Low preset is still the recommended choice.

At 3840x2160, none of the settings are playable. Low yields 27 average FPS, Medium 18 average FPS, and High 15 average FPS. Ultra is near unplayable at 12 average FPS. The data suggests that 4K is entirely out of reach for this combination.

The data indicates a pattern: as resolution increases, the average FPS drops are consistent, and the gap between Low and Ultra settings widens. The best experience per the measured rows is clearly at 1080p with the Low preset, delivering 66 average FPS. Those who prefer Medium settings at 1080p can achieve 44 average FPS, which is a balanced trade-off between visual fidelity and playability. However, no setting at 1440p or 4K provides a consistently smooth frame rate. The RX 570's 4 GB of memory and 224.0 GB/s bandwidth simply cannot handle Rust's demands at higher resolutions.

FAQ

Q: What is the highest average FPS achievable with this CPU and GPU combination?

A: The highest measured average FPS is 66, achieved at 1920x1080 resolution with the Low preset.

Q: Is the AMD Radeon RX 570 capable of running Rust at Ultra settings?

A: At 1080p Ultra, the combination produces 29 average FPS, which is below a playable threshold. At 1440p Ultra and 4K Ultra, the average FPS drops to 20 and 12 respectively, indicating the GPU cannot handle Ultra settings at any resolution.

Q: How does 1440p performance compare to 1080p performance for this combo?

A: At Low settings, moving from 1080p to 1440p reduces the average FPS from 66 to 46, a drop of 20 frames. At High settings, the drop is from 38 to 26, a 12-frame difference.

Q: Does the Intel Core i7-13700K become a bottleneck at any resolution?

A: No. The data shows the RX 570 is the limiting factor. The CPU has 16 cores and 24 threads, which is far more than Rust requires, and the FPS drops are consistent with GPU-bound behavior across resolutions.

CPU Role

The Intel Core i7-13700K is a Raptor Lake-S architecture processor with 16 cores and 24 threads. It has a base clock of 3.40 GHz and a boost clock of 5.40 GHz, with a 125 W TDP. It supports both DDR4 and DDR5 memory over a dual-channel bus, and it has a 30 MB shared L3 cache. This is a high-end desktop CPU, and its benchmark scores reflect that. It scores 30,745 in Cinebench R23 multi-core and 4,333 in PassMark single-thread. Its average benchmark score is 46,881, which places it at the 89th percentile for all CPUs.

However, in Rust, this CPU is utterly bottlenecked by the GPU. The data shows that the CPU is not the limiting factor in any of the measured scenarios. For example, the 3DMark 16-thread score is 10,717, and the single-thread score is 1,136, but none of this matters when the GPU is the RX 570. The CPU's role in this game is to feed the GPU with draw calls and game logic, but the RX 570's 2,048 shading units and 5.095 TFLOPS are simply not enough to keep up with the CPU's potential. The result is that the game remains GPU-bound at all settings and resolutions, but the low GPU performance caps the frame rate.

The CPU's 16 cores and 24 threads are largely idle in Rust, as the game likely uses fewer threads. The boost clock of 5.40 GHz helps with single-threaded tasks, but the RX 570's rasterization speed is the limiting factor. This is a clear case where the CPU's performance is not reflected in the game's frame rates; the processor is overqualified for the GPU it is paired with.

How This Combo Ranks

The combination of the Intel Core i7-13700K and the AMD Radeon RX 570 ranks 3553 out of 3723 tested combos for Rust. This places it in the bottom 5% of systems, which is a poor result for a CPU that ranks in the 89th percentile for all CPUs. The combo rank is a direct reflection of the GPU's limitations, as the RX 570 is clearly not suited for this game at any resolution above 1080p.

The CPU's own benchmark scores show it is capable of high performance in other contexts. For instance, the 4DMark max threads score is 12,412, and the Geekbench multi-core score is 19,429. But in Rust, the combo rank is dragged down by the GPU. The RX 570 has an average benchmark score of 28,766 and ranks in the 74th percentile for all GPUs, but its closest rivals are the AMD Radeon RX 6800M (with an average score of 28,874) and the NVIDIA Quadro RTX 8000 (with an average score of 28,421). These are not high-end parts, and the RX 570 is at the bottom of the stack. The combo rank reflects that the CPU is not the issue; the GPU is the classic 1080p part that cannot handle higher resolution.

In the context of all tested combos, this pairing is a poor match for Rust, but the data shows that the CPU is not the bottleneck. The GPU's 2,048 shading units and 4 GB of GDDR5 memory are the limiting factors. The combo rank of 3553 out of 3723 indicates that most other combinations deliver better performance in Rust, which is expected given the age and tier of the RX 570.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution scaling. At 1080p Low, the average FPS is 66. At 1440p Low, it drops to 46. At 4K Low, it falls to 27. This is a classic GPU-bound scaling pattern: moving from 1080p to 1440p reduces the frame rate by 20 frames (a 30% drop), and from 1440p to 4K reduces it by another 19 frames (a 41% drop). In percentage terms, 4K Low is only 41% of the 1080p Low performance.

At High settings, the scaling is even more dramatic. 1080p High is 38 average FPS, 1440p High is 26 average FPS, and 4K High is 15 average FPS. This indicates that the GPU is not just resolution-limited but also setting-limited. The RX 570's shading rate and memory bandwidth (224.0 GB/s) are insufficient to maintain a playable frame rate at 4K, even on Low.

The data indicates that the GPU is the limiting component. If the CPU were the bottleneck, the frame rate would not drop so significantly with resolution, because the CPU would be the same. The 27% drop from 1080p to 1440p at Low, and the 41% drop from 1440p to 4K, show that the GPU is doing all the heavy lifting. The i7-13700K has a boost clock of 5.40 GHz and is far more capable, but the RX 570's 5.095 TFLOPS are the limiting factor.

The scaling from 1080p to 4K at Low settings shows a 40.9% reduction in FPS (from 66 to 27), while at High settings it shows a 60.5% reduction (from 38 to 15). This is typical of a GPU that is not powerful enough to handle the pixel count and texture work. The fact that the 4K High is 15 average FPS, while 4K Low is 27, indicates that the GPU is also limited by the settings, not just the resolution.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's performance. The following breakdown is based solely on the measuredFps rows, which include average, minimum, and maximum FPS where available.

3840x2160 (4K)

• Low settings: 27 average FPS. No min or max values were measured.
• Medium settings: 18 average FPS, with a minimum of 15 and a maximum of 21.
• High settings: 15 average FPS. No min or max values were measured.
• Ultra settings: 12 average FPS. No min or max values were measured.

At 4K, the system is entirely unplayable. Even the Low preset only reaches 27 average FPS, which is below the 30 FPS threshold typically considered the bare minimum. The Ultra preset at 12 average FPS is a slideshow. The data shows that this combination should not be used at 4K for any setting.

2560x1440 (1440p)

• Low settings: 46 average FPS. No min or max values were measured.
• Medium settings: 31 average FPS, with a minimum of 26 and a maximum of 35.
• High settings: 26 average FPS. No min or max values were measured.
• Ultra settings: 20 average FPS. No min or max values were measured.

At 1440p, the Low preset is the only one that can maintain an average FPS above 30, but it is still not smooth. The Medium settings provide a stable frame rate with a min of 26, which is below the 30 threshold. High and Ultra are not recommended for any type of competitive play. The average FPS drops of 15 from Low to Medium (46 to 31), and 11 from Medium to High (31 to 20), show that the GPU is heavily stressed as settings increase.

1920x1080 (1080p)

• Low settings: 66 average FPS. No min or max values were measured.
• Medium settings: 44 average FPS, with a minimum of 38 and a maximum of 51.
• High settings: 38 average FPS. No min or max values were measured.
• Ultra settings: 29 average FPS. No min or max values were measured.

At 1080p, the Low preset delivers a smooth 66 average FPS, which is the only measured row that exceeds 60 FPS. The Medium preset offers 44 average FPS, which is playable but not ideal. High drops to 38 average FPS, and Ultra to 29 average FPS. The data shows a clear diminishing return: raising the settings from Low to Medium costs 22 FPS on average, while raising from Medium to High costs only 6 FPS, and from High to Ultra costs 9 FPS. The minimum FPS at Medium is 38, which is still playable, but the 51 maximum is not a stable high. The 1080p Low is the only configuration that can be considered smooth, and even then, the 4 GB VRAM may cause stutter in intense scenes.

The overall picture is that the AMD Radeon RX 570 is a 1080p-only GPU for this game, and even then, it requires the Low preset to achieve a comfortable frame rate. The Intel Core i7-13700K is not a factor in the results, as the GPU is the clear bottleneck. The combo rank of 3553 out of 3723 confirms that this is a low-performance pairing for Rust.
