Rust

The Intel Core i7-13700K paired with the AMD Radeon RX 580 presents a stark contrast in capabilities: a top-tier modern processor driving a mid-range GPU from an older generation. In Rust, this combination yields playable results primarily at 1080p with lower settings, while higher resolutions and presets push the system into unplayable territory. The following analysis breaks down the measured data for this specific pairing.

FAQ

Q: What is the best resolution for this CPU and GPU combo in Rust?

A: The only resolution where this combo achieves a consistently playable average frame rate is 1920x1080. At this resolution, the Low preset delivers 72.9 FPS, while Medium and High presets provide 46.5 and 43 FPS respectively. At 2560x1440, the best average is 53.5 FPS on Low settings, but this drops below 33 FPS on Medium and High.

Q: How does the Intel Core i7-13700K compare to its closest rivals in synthetic benchmarks?

A: The processor's average benchmark score of 47282 places it at the 93rd percentile of all CPUs. Its closest rival, the Intel Core i7-13700KF, scores 47334, a negligible 0.1% difference. The AMD EPYC 4364P trails by 0.3% with a score of 47131, while the Intel Core i9-12900F is 0.4% behind at 47081.

Q: What is the GPU's performance percentile and which rivals is it closest to?

A: The AMD Radeon RX 580 sits at the 53rd percentile of all GPUs with an average benchmark score of 13559. Its direct competitors are the NVIDIA GeForce GTX 570 (13564, 0% difference) and the NVIDIA GeForce GTX 950 (13549, 0.1% difference), showing this GPU is positioned firmly in the lower-midrange tier.

Q: What is the frame rate difference between Low and Ultra settings at 1920x1080?

A: The gap is substantial. At 1080p, the Low preset averages 72.9 FPS, while the Ultra preset drops to 32.6 FPS. This represents a 55% reduction in average frame rate when moving from the lowest to the highest quality settings.

Q: How much performance is lost when moving from 1920x1080 to 3840x2160?

A: The loss is severe across all settings. For example, on Low settings, the average frame rate falls from 72.9 FPS at 1080p to 31.1 FPS at 4K. On High settings, it drops from 43 FPS to 19.1 FPS, making 4K an unviable option for this hardware combination.

Q: What is this combo's ranking among all tested combinations in Rust?

A: The combo ranks 1579 out of 1717 tested combinations. This places it in the bottom 8% of all tested systems, confirming that this pairing is not well-suited for demanding scenarios in Rust.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. It has a base clock of 3.40 GHz and a boost clock of 5.40 GHz. The processor supports both DDR4 and DDR5 memory in a dual-channel configuration. Its L3 cache totals 30 MB shared across the cores, with 2 MB of L2 cache per core and 80 KB of L1 cache per core.

Synthetic benchmarks show the CPU's substantial headroom. In Cinebench R23, it scores 39000 in multicore and 5505 in singlecore tests. PassMark results emphasize its strong multi-threaded capabilities, with a multithread score of 45887 and a single-thread score of 4333. The processor also demonstrates strong integer math performance (154446) and floating-point math (114867) in PassMark tests.

For Rust, the CPU's role is likely more about ensuring the GPU is fully utilized rather than being the bottleneck itself. The processor's high single-thread score of 5505 in Cinebench R23 suggests it can handle the game's simulation and logic threads efficiently. However, the measured frame rates in this combo indicate that the GPU becomes the limiting factor long before the CPU's resources are exhausted. The CPU's percentile ranking of 93rd among all processors contrasts sharply with the GPU's 53rd percentile, explaining why this pairing underperforms in a game like Rust.

GPU Role

The AMD Radeon RX 580 uses the Polaris 20 chip built on GlobalFoundries' 14 nm process, featuring GCN 4.0 architecture. It has a base clock of 1257 MHz and a boost clock of 1340 MHz, with 8 GB of GDDR5 memory on a 256-bit bus providing 256.0 GB/s of bandwidth. The GPU includes 2304 shading units, 144 texture mapping units, and 32 ROPs.

The GPU's compute capabilities are modest: it offers 6.175 TFLOPS of FP32 performance and a texture rate of 193.0 GTexel/s. Its pixel rate is 42.88 GPixel/s. In PassMark DirectX tests, scores range from 43 in DirectX 12 to 124 in DirectX 9, indicating limited modern API performance. The GPU draws 185 W TDP and requires a 450 W power supply.

This GPU is clearly the limiting component in Rust. Its 53rd percentile standing and average score of 13559 align with its age and architecture. The fact that it sits closest to the NVIDIA GTX 570 and GTX 950 in performance shows its tier. In Rust, the GPU's limitations manifest dramatically in the 4K results, where even Low settings only achieve 31.1 FPS. The measured data shows that this GPU cannot push modern survival games at higher resolutions, regardless of the capable CPU driving it.

Measured FPS Breakdown

The measured FPS data reveals a clear pattern of performance degradation as resolution and settings increase.

At 3840x2160, the combo struggles universally. Low settings average 31.1 FPS, which is the only setting above 20 FPS. Medium averages 20.3 FPS, High drops to 19.1 FPS, and Ultra bottoms out at 13.6 FPS. None of these are playable in a competitive survival game.

At 2560x1440, the situation improves slightly. Low settings achieve 53.5 FPS, which is borderline acceptable. Medium drops to 32.2 FPS, High to 27.5 FPS, and Ultra to 24.6 FPS. Only the Low preset approaches playability at this resolution.

At 1920x1080, the combo finds its only viable range. Low settings average 72.9 FPS, which is smooth. Medium averages 46.5 FPS, and High averages 43 FPS, both of which are playable. Ultra drops to 32.6 FPS, which is borderline and may feel stuttery in intense moments.

The data shows a consistent trend: moving from Low to Medium costs roughly 20-30 FPS depending on resolution, while moving from Medium to High costs another 3-5 FPS. The jump from High to Ultra is the most punishing, with significant frame rate drops at every resolution.

How This Combo Ranks

This combo ranks 1579 out of 1717 tested combinations in Rust, placing it in the bottom 8% of all tested systems. This low ranking is a direct consequence of the massive performance gap between the CPU and GPU. The i7-13700K ranks at the 93rd percentile among all CPUs, while the RX 580 sits at only the 53rd percentile among GPUs.

The CPU's synthetic scores reinforce this imbalance. Its PassMark multithread score of 45887 and Cinebench R23 multicore score of 39000 are elite-tier results. In contrast, the GPU's PassMark G3D score of 8813 is firmly mid-range. This pairing creates a scenario where the CPU is never the bottleneck, but the GPU cannot deliver the frame rates needed to take advantage of the CPU's capabilities.

In practical terms, this ranking means that most other tested combinations will outperform this setup in Rust. The GPU's age and architecture hold back what would otherwise be a very capable gaming system. For players using this specific combo, the data suggests that the experience will be limited to lower resolutions and settings.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is at 1920x1080 with the Low preset, which averages 72.9 FPS. This is the only configuration that achieves a consistently smooth frame rate above 60 FPS. The Medium preset at 1080p averages 46.5 FPS, which is playable but may have noticeable dips during intensive scenes.

For players who prioritize visual quality over frame rate, the High preset at 1080p averages 43 FPS, which remains playable. The Ultra preset at 1080p averages 32.6 FPS, which is borderline and not recommended for fast-paced gameplay.

At 2560x1440, only the Low preset (53.5 FPS) is viable. The Medium preset at 32.2 FPS is too inconsistent for competitive play. At 3840x2160, all settings produce average frame rates below 32 FPS, making 4K effectively unplayable for this hardware combination.

The data clearly indicates that the best balance of visual fidelity and performance is the Medium preset at 1080p, offering 46.5 FPS. However, for players who demand smoothness, the Low preset at 1080p is the only setting that provides a truly fluid experience. Given the GPU's performance ceiling, there is no configuration that offers both high visual quality and high frame rates with this combo.
