Rust

The AMD Ryzen 7 5800X3D paired with the NVIDIA GeForce RTX 3080 Ti delivers a specific performance profile in Rust, a survival title known for its demanding simulation and rendering loads. This combination ranks 974th out of 3,723 tested combos, placing it in the upper 26% of all hardware pairings, a solid mid-to-high tier position for this particular game. The data suggests a balanced system where neither component is drastically underpowered, but the frame rates reveal clear scaling patterns tied to resolution and settings.

How This Combo Ranks

The combo’s rank of 974 out of 3,723 tested combinations indicates that roughly three-quarters of tested systems perform better in Rust. This is not a top-tier configuration, but it is far from a low-end one. The position is largely explained by the RTX 3080 Ti’s age and the 5800X3D’s strengths in specific workloads. The CPU ranks at the 80th percentile against all CPUs, which is strong, while the GPU sits at the 83rd percentile against all GPUs. This near-identical percentile placement suggests the pairing is well-matched in general compute power, but the game’s engine may not fully exploit the CPU’s unique 3D V-Cache advantage.

In terms of direct rivals, the CPU’s average benchmark score of 27,896 is statistically tied with the AMD Ryzen 7 6800U (27,887, 0% delta), the Intel Core i9-10900K (27,872, 0.1% delta), and the AMD Ryzen AI 5 PRO 340 (27,932, -0.1% delta). The 5800X3D is essentially neck-and-neck with these parts in synthetic averages, but Rust’s real-world performance can diverge from those numbers. The GPU’s average score of 41,187 places it 0.8% ahead of the AMD Radeon Pro 5300 (40,870) and 2% ahead of the NVIDIA GeForce RTX 5070 (40,377), while trailing the NVIDIA Tesla M40 24 GB by 1.2% (41,707) and the Tesla M40 by 1.7% (41,897). These rival deltas are small, meaning the 3080 Ti is in a competitive performance band, but the newer RTX 5070’s lower average score is a notable data point for this benchmark set.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture with the GA102 chip, fabricated on Samsung’s 8 nm process. It features 10,240 shading units, 320 texture mapping units, and 112 render output units, alongside 80 RT cores and 320 tensor cores. The GPU operates at a base clock of 1365 MHz and a boost clock of 1665 MHz, with memory running at 1188 MHz, translating to 19 Gbps effective GDDR6X speed. The 12 GB memory pool is connected via a 384-bit bus, yielding a substantial bandwidth of 912.4 GB/s.

In Rust, this GPU configuration shows a clear pattern: the card is the primary driver of performance at higher resolutions, but its role diminishes at 1080p. The data indicates that the 3080 Ti’s raw rasterization power—34.10 TFLOPS FP32—is sufficient for high frame rates, but the memory bandwidth becomes critical at 4K. At 3840x2160, the average FPS drops from 91 on Low settings to 52 on High and 39 on Ultra, a spread of 52 FPS that directly correlates with the increased memory and shading demands. The 12 GB VRAM capacity is adequate for Rust’s textures, but the bandwidth is the limiting factor in the most demanding presets.

Interestingly, the GPU’s performance in synthetic benchmarks does not fully translate to Rust. The PassMark G3D score of 26,896 and Geekbench Vulkan score of 192,697 indicate strong compute capabilities, yet the game’s engine appears to respond more to raw fill rates. The pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s are high, but at 4K Ultra, the card still only manages 39 FPS, suggesting the game has heavy overdraw or shader complexity that taxes these units.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic pattern of GPU-bound behavior at higher resolutions. At 1920x1080, the combo achieves 190 FPS on Low settings, which drops to 154 FPS at 2560x1440 and 91 FPS at 3840x2160. This represents a 52% reduction from 1080p to 1440p, and a further 41% reduction from 1440p to 4K on Low settings. This steep decline indicates the GPU is the limiting component at these resolutions, as the CPU’s 8 cores and 16 threads are sufficient to feed the graphics card.

On Medium settings, the pattern is similar but with a narrower absolute gap: 150 FPS at 1080p, 103 FPS at 1440p, and 61 FPS at 4K. The percentage drops are 31% and 41%, respectively, showing that the game becomes progressively more GPU-bound as resolution increases. The High settings preset follows the same trend: 127 FPS at 1080p, 87 FPS at 1440p, and 52 FPS at 4K. The Ultra preset, which is the most demanding, shows the largest relative drop: 96 FPS at 1080p, 66 FPS at 1440p, and 39 FPS at 4K.

The fact that the 1080p to 1440p drop is consistently around 30-40% while the 1440p to 4K drop is also 30-40% suggests that the GPU is scaling with pixel count as expected. However, the 1080p results, particularly the 190 FPS on Low, indicate that the CPU is not holding the system back at lower resolutions. This is a balanced system where the bottleneck shifts from the CPU at 1080p Low to the GPU at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. On Low settings, the average FPS is 190, which is excellent for competitive play. Medium settings yield 150 FPS average, with a minimum of 128 FPS and a maximum of 173 FPS, showing a tight frame time distribution. High settings drop to 127 FPS average, while Ultra settings reduce the average to 96 FPS. The 1080p results show a clear settings hierarchy, with each tier costing roughly 20-30 FPS.

Moving to 2560x1440, the performance remains strong but the GPU starts to feel the load. Low settings produce 154 FPS average, which is still very playable. Medium settings drop to 103 FPS average, with a minimum of 88 FPS and a maximum of 119 FPS. High settings yield 87 FPS average, and Ultra settings bring the average down to 66 FPS. The 1440p results indicate that the RTX 3080 Ti can handle high refresh rate gaming at this resolution for most settings, but Ultra may require a variable refresh rate monitor to smooth out dips.

At 3840x2160, the GPU is clearly the bottleneck. Low settings achieve 91 FPS average, which is respectable for 4K. Medium settings drop to 61 FPS average, with a minimum of 52 FPS and a maximum of 70 FPS. High settings reduce the average to 52 FPS, and Ultra settings bottom out at 39 FPS average. These 4K numbers suggest that the combo is only suitable for 4K gaming at Low or Medium settings, with High and Ultra requiring significant compromises or upscaling technologies.

The Medium settings data across all resolutions provides the most complete picture, as it includes min and max FPS. At 1080p Medium, the 128 FPS minimum ensures smooth gameplay. At 1440p Medium, the 88 FPS minimum is still acceptable. At 4K Medium, the 52 FPS minimum may cause noticeable stuttering in fast-paced scenes. This data shows that the combo’s sweet spot is 1440p with Medium to High settings, where it maintains frame rates above 87 FPS.

CPU Role

The AMD Ryzen 7 5800X3D is a unique 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer, on AMD’s Socket AM4 platform. It has a base clock of 3.40 GHz and a boost clock of 4.50 GHz, with a 105 W TDP. The key differentiator is the 96 MB shared L3 cache, which is significantly larger than typical processors of its generation. This large cache is designed to reduce memory latency and improve performance in games that benefit from high cache hit rates.

In Rust, the CPU’s role is evident at 1080p, where the frame rates are highest. The 190 FPS on Low settings suggests that the 5800X3D’s 8 cores are well-utilized, but the game may not be heavily threaded. The 3DMark scores show strong multi-threaded performance: 7,299 in the 16-thread test and 7,285 in the max-thread test, indicating that the CPU can handle parallel workloads. However, the single-thread score of 884 in 3DMark and 1,452 in Cinebench R23 suggest that individual core performance is adequate but not exceptional.

The CPU’s benchmark scores are competitive with its nearest rivals. The PassMark multi-thread score of 28,309 is close to the average of 27,896, and the Cinebench R23 multi-core score of 14,317 is strong for an 8-core part. The Geekbench multi-core score of 11,765 further confirms the CPU’s capability. These numbers indicate that the 5800X3D is not a bottleneck in Rust, even at 1080p, where the GPU is less stressed.

The 96 MB L3 cache is particularly relevant for Rust, which features a large, persistent game world with many entities. The cache helps keep frequently accessed data on-die, reducing the need to fetch from system memory. This is likely why the 1080p Low settings result of 190 FPS is so high, as the CPU can maintain high instruction throughput without memory stalls. The CPU’s 51.2 GB/s memory bandwidth and dual-channel DDR4 support are sufficient for the game’s demands.
