Rust

Rust is a demanding survival title that stresses both CPU and GPU, and the benchmark data for the AMD Ryzen 7 5800X paired with the NVIDIA GeForce RTX 4080 shows a system that scales predictably across resolutions, with the GPU becoming the primary bottleneck at 4K while the CPU holds its own at lower resolutions. The measured FPS rows provide a clear picture of how this combo behaves across three resolutions and four quality presets, and the analysis below interprets those numbers in the context of the component specifications and the combo’s ranking against 3,722 other tested configurations.

Resolution Scaling

The measuredFPS data reveals a steep performance drop as resolution increases, which is typical for a GPU-bound scenario at higher pixel counts. At 1920x1080 with Low settings, the combo achieves an average of 202 FPS. Moving to 2560x1440 Low, the average falls to 178 FPS, a decline of roughly 12%. At 3840x2160 Low, the average drops further to 117 FPS, which is about 34% lower than the 1440p figure and 42% below the 1080p result. This scaling pattern indicates that the RTX 4080’s rendering workload grows substantially with pixel count, and the CPU is not the limiting factor at these lower settings.

For High settings, the trajectory is similar but with lower absolute numbers. At 1080p High, the average is 163 FPS. At 1440p High, it drops to 112 FPS, a 31% reduction. At 4K High, the average is 66 FPS, which is 41% below the 1440p High result and 60% below the 1080p High result. The gap between 1080p and 4K at High settings is larger than at Low settings, suggesting that the higher quality preset increases the GPU’s per-frame cost, making resolution scaling even more pronounced.

The Medium settings row provides the only min and max FPS data in the pack. At 1080p Medium, the average is 174 FPS, with a minimum of 148 FPS and a maximum of 200 FPS. At 1440p Medium, the average is 133 FPS, with a minimum of 113 FPS and a maximum of 153 FPS. At 4K Medium, the average is 79 FPS, with a minimum of 67 FPS and a maximum of 90 FPS. These min/max values show that frame pacing remains relatively stable, but the spread between min and max narrows as resolution rises, which is consistent with the GPU becoming the bottleneck.

Ultra settings exhibit the most severe scaling. At 1080p Ultra, the average is 124 FPS. At 1440p Ultra, it drops to 85 FPS, a 31% reduction. At 4K Ultra, the average falls to 50 FPS, which is 41% below the 1440p Ultra result and 60% below the 1080p Ultra figure. The 4K Ultra result of 50 FPS is the lowest in the entire dataset, indicating that this preset pushes the RTX 4080 to its limits at that resolution.

The data suggests that the limiting component shifts with resolution. At 1080p, the CPU’s role is more significant, as evidenced by the relatively small FPS gap between Low (202 FPS) and High (163 FPS) — only 19% — which implies the GPU is not fully saturated at Low settings. At 4K, the GPU is clearly the limiting factor, as the drop from Low to High is 44% (117 FPS to 66 FPS), and from Low to Ultra is 57% (117 FPS to 50 FPS). This is a classic sign of GPU-bound performance at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with a 5 nm process node, featuring 16 GB of GDDR6X memory on a 256-bit bus, yielding a memory bandwidth of 716.8 GB/s. The GPU’s base clock is 2205 MHz, with a boost clock of 2505 MHz. Memory clock is 1400 MHz, which translates to 22.4 Gbps effective. These specifications directly influence the measured FPS, particularly at 4K where memory bandwidth and raw compute are critical.

The RTX 4080’s 16 GB VRAM is ample for Rust at any of the tested presets, as the game’s texture and asset demands are unlikely to exceed this capacity at 1080p or 1440p. At 4K Ultra, the 50 FPS average suggests the GPU is heavily loaded, but the VRAM size is not the bottleneck — rather, it is the shader and rasterization workload. The GPU’s 9728 shading units, 304 TMUs, and 112 ROPs, along with a pixel rate of 280.6 GPixel/s and a texture rate of 761.5 GTexel/s, define its ability to process the game’s geometry and effects.

The RTX 4080’s compute performance, measured at 48.74 TFLOPS for FP32 and FP16, is reflected in the benchmark scores. Its passmark G3D score is 34457, and its 3DMark Steel Nomad DX12 score is 6567. The GPU’s percentile vs all GPUs is 86, meaning it outperforms 86% of all GPUs in the database. Its nearest rivals include the NVIDIA GeForce RTX 4080 SUPER with an average score of 54209 and a deltaPct of 0.1, and the AMD Radeon RX 6750 GRE 12 GB with an average score of 55698 and a deltaPct of -2.6. The RTX 4080’s own average benchmark score is 54247, placing it just 0.1% above the SUPER variant and 2.6% below the Radeon RX 6750 GRE.

In Rust specifically, the GPU’s role is most evident at 4K. The jump from Low (117 FPS) to Medium (79 FPS) is a 32% reduction, while the jump from Medium to High (66 FPS) is another 16% reduction. This progressive decline indicates that each quality tier adds significant GPU work, from shadow resolution to texture filtering and post-processing effects. The RTX 4080’s boost clock of 2505 MHz provides the headroom needed to maintain playable frame rates at 4K, but the data shows that Ultra settings at 4K are not viable for smooth gameplay, as 50 FPS is below the 60 FPS threshold many players target.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 (Vermeer) part with 8 cores and 16 threads, base clock of 3.80 GHz and boost clock of 4.70 GHz. It has 64 KB of L1 cache per core, 512 KB of L2 per core, and 32 MB of L3 cache. The CPU supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s, and it uses the AMD Socket AM4. Its TDP is 105 W, and it was released with a launch MSRP of $449.

In Rust, the CPU’s impact is most visible at 1080p where the GPU is less stressed. At 1080p Low, the combo achieves 202 FPS, which is the highest figure in the dataset. At 1080p High, the average is 163 FPS, and at 1080p Ultra, it is 124 FPS. The difference between Low and Ultra at 1080p is 78 FPS, or 39%. This indicates that the CPU can feed the GPU at lower resolutions, but the GPU’s work increases with quality settings, so the CPU is not the sole bottleneck. The 5800X’s single-thread performance, as shown by its 3DMark single-thread score of 943 and Cinebench R23 single-core score of 1574.5, is strong enough to handle Rust’s simulation and game logic at high frame rates.

The CPU’s multi-threaded capabilities, evidenced by a Cinebench R23 multicore score of 15476 and a Geekbench multicore score of 11036, are relevant because Rust can utilize multiple cores for world generation and entity updates. The 5800X’s 8 cores and 16 threads provide sufficient parallelism for these tasks. Its passmark multithread score is 27732, and its 3DMark 16-thread score is 7586, which is nearly identical to its 3DMark max-thread score of 7578, suggesting that the CPU is well-utilized at high thread counts.

The CPU’s percentile vs all CPUs is 81, and its nearest rivals are the Intel Core Ultra 5 135H with an average score of 29093 and a deltaPct of 0.1, and the Intel Xeon Phi 7210 with an average score of 29245 and a deltaPct of -0.4. The 5800X’s average benchmark score is 29123, placing it 0.1% above the Core Ultra 5 135H and 0.4% below the Xeon Phi 7210. This positioning suggests that the 5800X is a solid mid-range performer in synthetic tests, which translates to its ability to keep up with the RTX 4080 in Rust at most settings.

At 4K, the CPU’s role diminishes, as the GPU becomes the limiting factor. The FPS differences between presets at 4K are larger than at 1080p, indicating that the GPU is saturated. However, the CPU must still maintain minimum frame rates, and the data shows that at 4K Medium, the minimum FPS is 67, which is above the 60 FPS threshold. This suggests that the 5800X is capable of providing consistent frame delivery even when the GPU is under heavy load.

How This Combo Ranks

The combo of the AMD Ryzen 7 5800X and NVIDIA GeForce RTX 4080 ranks 343rd out of 3,723 tested combinations in Rust, placing it in the top 9.2% of all combos. This high ranking is driven by the RTX 4080’s strong GPU performance (86th percentile) and the 5800X’s respectable CPU performance (81st percentile). In the context of Rust, which is known to be CPU-intensive at lower resolutions, this pairing balances both components well.

The combo’s rank is particularly impressive given that the GPU is end-of-life, having been released in September 2022, and the CPU was released in November 2020. Despite the age of both components, the measured FPS results show that this pairing can handle Rust at high frame rates across all tested resolutions, with the caveat that 4K Ultra falls below 60 FPS.

Compared to other combos in the database, the 343rd rank out of 3,723 indicates that this is a high-performing configuration, but not the absolute top. The data suggests that to achieve a higher rank, one would need either a stronger GPU (e.g., the RTX 4080 SUPER, which is 0.1% faster in average benchmark score) or a faster CPU (e.g., a newer Ryzen part with higher single-thread performance). However, the current combo’s performance in Rust is strong enough to deliver playable frame rates at 1440p Ultra (85 FPS) and 4K High (66 FPS).

The rank also reflects the balanced nature of this pairing. In Rust, where the CPU can bottleneck at 1080p, the 5800X’s 8 cores and 16 threads, along with its 4.70 GHz boost clock, provide enough headroom to avoid severe CPU limitations. At 4K, the RTX 4080’s 16 GB of VRAM and 716.8 GB/s bandwidth ensure that the GPU is the primary driver of performance, which is expected for a survival game with large draw distances and complex lighting.
