Rust

The AMD Ryzen 7 7800X3D paired with the Intel Arc B580 produces a distinctive performance profile in Rust, one that shifts character dramatically depending on resolution and quality settings. Measured data places this combination at rank 1340 out of 1717 tested combos, a position that reflects the GPU's mid-range standing rather than the CPU's high-end pedigree. The Arc B580's 12 GB of GDDR6 memory on a 192-bit bus delivers 456.0 GB/s of bandwidth, and its 2670 MHz base and boost clocks are identical, suggesting a fixed operating point. At 4K Ultra, the combo manages only 21.1 FPS, while dropping to 4K Low yields 52.9 FPS — a swing that points to the GPU being the primary constraint at higher resolutions, as the settings change alone nearly triples performance.

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

The Intel Arc B580 carries 12 GB of GDDR6 memory across a 192-bit interface, yielding 456.0 GB/s of bandwidth. Its 2670 MHz clock speed applies to both base and boost states, a uniform figure that simplifies analysis. With 2560 shading units, 160 TMUs, and 80 ROPs, the card's compute throughput reaches 13.67 TFLOPS FP32. These specifications place the GPU in the 66th percentile of all GPUs, with an average benchmark score of 23021. The nearest rival, the NVIDIA GeForce RTX 4060, scores 23181, a delta of -0.7%, meaning the Arc B580 trails by less than a single percent in aggregate benchmarks. That close margin suggests the two cards should behave similarly, yet Rust's measured frames tell a more nuanced story.

At 1080p Low, the combo hits 131.8 FPS, but at 4K Ultra it collapses to 21.1 FPS. The 12 GB VRAM capacity is not the limiting factor here — even at 4K, Rust's textures rarely exceed that allocation on these settings. Instead, the 2670 MHz clock and 456.0 GB/s bandwidth appear insufficient to feed the rendering pipeline at high pixel counts. The data shows a clear pattern: as resolution climbs, the GPU's fixed compute resources spread thinner, and the frame rate drops proportionally. The 80 ROPs, responsible for pixel output, become a bottleneck at 4K, where 8.3 million pixels per frame must be rasterized. This explains why the gap between Low and Ultra settings widens from 76.4 FPS at 1080p to 31.8 FPS at 4K — the GPU's fill-rate limits dominate at higher resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of the Ryzen 7 7800X3D and Arc B580 achieves rank 1340 out of 1717 tested combinations in Rust. That places it in the bottom 22% of all combos, a surprisingly low position given the CPU's strength. The Ryzen 7 7800X3D sits in the 87th percentile of all CPUs with an average benchmark score of 31580, but the Arc B580's 66th percentile GPU standing drags the overall combo down. The disparity between CPU and GPU performance tiers is stark: the processor outranks the graphics card by 21 percentile points, indicating a severe bottleneck in the GPU at most settings.

The nearest rival CPUs to the 7800X3D include the Intel Core i7-12700F with a delta of 0.1% and the AMD Ryzen 9 5980HX at 0.3% — both essentially tied in synthetic scores. Yet in Rust, the combo's rank suggests the GPU dominates the outcome. The Arc B580's nearest GPU rival, the RTX 4060, sits at a -0.7% delta, meaning the two are nearly interchangeable in raw benchmarks. However, the measured FPS in Rust does not reflect that parity at higher resolutions, where the Arc B580's 4K Ultra score of 21.1 FPS would likely trail the RTX 4060 by a wider margin than the synthetic delta implies. The combo's low rank likely stems from the GPU's inability to maintain playable frame rates at 4K, a weakness that no amount of CPU headroom can compensate for.

The GPU launched at 249 USD, a mid-range price point, which aligns with its 66th percentile GPU ranking.

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

The measured FPS data across three resolutions and four settings presets reveals a clear hierarchy. At 1080p, Low yields 131.8 FPS, Medium drops to 88.2, High to 75.3, and Ultra to 55.4. The step from Low to Medium costs 43.6 FPS, while the step from High to Ultra costs only 19.9 FPS — diminishing returns at the top end. For 1440p, Low hits 91.3 FPS, Medium 60.0, High 52.6, and Ultra 41.8. The Medium preset at 1440p is the first to cross the 60 FPS threshold, making it the minimum viable option for smooth gameplay at this resolution.

At 4K, the situation degrades sharply: Low produces 52.9 FPS, Medium 37.9, High 28.2, and Ultra 21.1. None of these reach 60 FPS, so 4K is not recommended for this combo in Rust. The best overall experience per the data is 1080p Medium at 88.2 FPS, which balances visual quality with a comfortable frame rate margin above 60. Alternatively, 1440p Low at 91.3 FPS offers similar performance with higher resolution, though it sacrifices visual fidelity. For players prioritizing smoothness over detail, 1080p Low at 131.8 FPS is the clear choice, especially in a survival game where reaction time matters in PvP encounters.

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

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound pattern. At Low settings, 1080p produces 131.8 FPS, 1440p produces 91.3 FPS, and 4K produces 52.9 FPS. This represents a 60% drop from 1080p to 4K, roughly proportional to the pixel count increase from 2.1 million to 8.3 million pixels. At Ultra settings, the drop is even steeper: 55.4 FPS at 1080p falls to 41.8 at 1440p and 21.1 at 4K, a 62% reduction. The consistency of these drops — around 60-62% across all settings — strongly indicates the GPU's pixel throughput is the limiting factor.

The Arc B580's 80 ROPs and 213.6 GPixel/s pixel rate determine how fast frames can be rasterized. At 4K, the demand on these ROPs increases fourfold compared to 1080p, and the measured FPS drops accordingly. The CPU's role is minimal here; the Ryzen 7 7800X3D's 8 cores and 16 threads with a 5.00 GHz boost clock can easily feed the GPU at any resolution. The data shows that resolution scaling affects frame rates almost linearly with pixel count, a signature of GPU-bound performance. The 12 GB VRAM does not appear to cause texture-swapping issues, as the FPS drops are smooth rather than stutter-prone.

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

The AMD Ryzen 7 7800X3D brings 8 cores and 16 threads on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its 96 MB of shared L3 cache is substantial, and the CPU's 120 W TDP suggests efficient power delivery. In synthetic benchmarks, it scores 29149 in Cinebench R23 multi-core and 4115 in single-core, with a Passmark multi-thread score of 34293. These numbers place it in the 87th percentile of all CPUs, yet the combo's rank in Rust is only 1340 out of 1717 — the GPU severely limits the system.

Rust is known for being CPU-intensive in its simulation and physics, but the measured data shows that this CPU has ample headroom. The 3dmark 16-thread score of 7980 and max-thread score of 7967 indicate consistent multi-threaded performance, while the 2-thread score of 1887 shows strong single-thread capability. The nearest CPU rivals include the Intel Core i7-12700F at a 0.1% delta and the AMD Ryzen 7 8700G at 0.6%, all within a fraction of a percent in average score. In Rust, the CPU's influence is likely masked by the GPU bottleneck at higher resolutions, but at 1080p Low, the 131.8 FPS result suggests the CPU can push frame rates well beyond what the GPU delivers at 4K.

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

At 1920x1080, the measured average FPS values are: Low 131.8, Medium 88.2, High 75.3, and Ultra 55.4. The range from Low to Ultra spans 76.4 FPS, the widest of any resolution. At 2560x1440, the values are: Low 91.3, Medium 60.0, High 52.6, and Ultra 41.8. The range narrows to 49.5 FPS, indicating that the GPU's limits begin to compress the settings' impact. At 3840x2160, the values are: Low 52.9, Medium 37.9, High 28.2, and Ultra 21.1. The range is just 31.8 FPS, the smallest spread.

The pattern across all resolutions is consistent: Low settings provide roughly double the frame rate of Ultra settings. At 1080p, the ratio is 2.38x (131.8 vs 55.4), at 1440p it is 2.18x (91.3 vs 41.8), and at 4K it is 2.51x (52.9 vs 21.1). This consistency suggests the settings presets affect the GPU workload proportionally, regardless of resolution. The Medium preset at 1440p produces exactly 60.0 FPS, a convenient benchmark for playability. The highest recorded frame rate is 131.8 FPS at 1080p Low, and the lowest is 21.1 FPS at 4K Ultra. These numbers provide a clear picture: this combo is best suited for 1080p gaming, adequate for 1440p at medium settings, and not viable for 4K beyond the lowest preset.
