Rust

The benchmark data for Rust, captured with an AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 3080, reveals a title that scales predictably with resolution but demonstrates a pronounced sensitivity to graphics settings. The combination ranks at 496 out of 1717 tested configurations, placing it in the upper tier of systems for this survival title. The measured frame rates across 1080p, 1440p, and 4K resolutions, combined with the CPU and GPU’s synthetic benchmark profiles, offer a clear picture of where the performance bottlenecks lie in this specific pairing.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a substantial and consistent drop in frame rates across all settings, underscoring the RTX 3080’s increasing workload as pixel count rises. At High settings, the average frame rate falls from 124.5 FPS at 1080p to 81.7 FPS at 1440p, a reduction of roughly 34%. Moving to 4K further cuts performance to 50.9 FPS, a 37% drop from the 1440p figure and a total reduction of 59% from the 1080p baseline. This steep decline indicates that at 4K, the GPU is the primary limiting component, as the pixel throughput demands begin to outpace the card’s capabilities in this title.

The scaling pattern at Low settings is even more dramatic. At 1080p, the system achieves an average of 206.1 FPS, which is a mark that suggests the CPU is capable of feeding the GPU at lower resolutions. However, at 1440p, this figure drops to 149.9 FPS, and at 4K, it plummets to 87 FPS. The 4K Low result is a 58% reduction from the 1080p Low score. This larger percentage drop compared to High settings suggests that when graphical load is minimized, the RTX 3080’s raw compute power becomes the deciding factor, and the 4K resolution simply presents too many pixels for the card to maintain high frame rates, even with minimal shading work.

Analyzing the Ultra preset reveals a similar trend. The system manages 91.7 FPS at 1080p, which drops to 63.1 FPS at 1440p and finally to 35.4 FPS at 4K. The 4K Ultra result is particularly telling, as it falls below the 60 FPS threshold and demonstrates that this configuration cannot deliver a smooth experience at maximum fidelity and resolution. The data suggests that 1440p is the sweet spot for this pairing with High or Medium settings, offering a balance between visual quality and frame rate, while 1080p is where the CPU and GPU combination can fully stretch its legs, particularly at lower settings.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, manufactured on an 8 nm process at Samsung. It features 8704 shading units, 272 texture mapping units, and 96 raster output pipelines. The card’s memory subsystem is a key asset: 10 GB of GDDR6X on a 320-bit bus provides a bandwidth of 760.3 GB/s. This high bandwidth is critical for Rust’s large, streamed game world, where texture and asset loading can heavily tax memory throughput. The memory clock runs at 1188 MHz, translating to 19 Gbps effective, while the GPU core operates at a base clock of 1440 MHz and a boost clock of 1710 MHz.

In terms of raw computational throughput, the RTX 3080 delivers 29.77 TFLOPS of FP32 performance. This considerable compute power is reflected in its benchmark scores, with a Passmark G3D score of 25086 and a 3DMark Steel Nomad DX12 score of 4407. The GPU’s percentile rank of 80 versus all GPUs places it in the high-performance tier, but its average benchmark score of 35787 is marginally lower than the AMD Radeon RX 7900 GRE, which has a 0.9% higher score. This synthetic proximity to rivals like the NVIDIA GeForce RTX 5070 Ti Mobile, which is only 1% higher in score, suggests that in compute-heavy tasks, the 3080 remains competitive.

The measured FPS data confirms the GPU’s role as the primary bottleneck at higher resolutions. The drop from 87 FPS at 4K Low to 35.4 FPS at 4K Ultra is a 59% reduction, driven by the increased pixel shading and memory pressure. While the 10 GB VRAM capacity is sufficient for Rust at these settings, the card’s compute units are clearly saturated at 4K with High and Ultra presets. The texture rate of 465.1 GTexel/s and pixel rate of 164.2 GPixel/s are high, but the sheer number of pixels at 3840x2160 overwhelms the card when settings are maxed out, leading to sub-60 FPS performance.

Measured FPS Breakdown

At 1920x1080, the configuration shows strong CPU-bound behavior at lower settings. The Low preset yields an average of 206.1 FPS, which is a significant jump from the Medium preset’s 144.7 FPS. High settings produce 124.5 FPS, and Ultra drops to 91.7 FPS. The scaling from Low to Ultra at 1080p is a 55% performance reduction, indicating that even at this resolution, the GPU’s workload increases substantially with visual fidelity. The fact that the system exceeds 200 FPS at Low suggests that the Ryzen 7 5800XT, with its 8 cores and 16 threads, is capable of keeping the RTX 3080 well-fed at lower graphical loads.

Moving to 2560x1440, the frame rates become more balanced between CPU and GPU limits. The Low preset still delivers a high 149.9 FPS, but the Medium preset drops to 98.2 FPS. High settings average 81.7 FPS, while Ultra falls to 63.1 FPS. The gap between Low and Medium at this resolution is 51.7 FPS, which is narrower than at 1080p, suggesting the GPU is starting to become more of a limiting factor. The Ultra preset at 1440p remains playable, staying just above 60 FPS, but the data shows that pushing to 4K will be challenging.

At 3840x2160, the RTX 3080’s limits are clearly exposed. The Low preset averages 87 FPS, which is the only setting that provides a high-refresh experience at this resolution. Medium drops to 56.8 FPS, High to 50.9 FPS, and Ultra to 35.4 FPS. The difference between Low and Medium at 4K is 30.2 FPS, a substantial penalty for a single step up in settings. The progression from 1080p Low to 4K Low shows a 58% reduction, while the same progression at Ultra shows a 61% reduction. This consistency indicates that resolution scaling is the dominant factor in frame rate decline, regardless of settings.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 architecture processor, codenamed Vermeer, manufactured on a 7 nm process at TSMC. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The CPU’s cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB L3 cache. This large L3 cache is beneficial for gaming workloads that require fast access to shared data. The processor’s memory support is for DDR4 with a dual-channel bus, providing a bandwidth of 51.2 GB/s.

In synthetic benchmarks, the 5800XT demonstrates strong single-threaded performance, with a Cinebench R23 single-core score of 3359 and a Passmark single-thread score of 3538. Its multi-threaded capabilities are equally impressive, with a Cinebench R23 multicore score of 23794 and a Passmark multithread score of 27988. The CPU’s overall percentile rank is 86, placing it above most other processors. Its average benchmark score of 29774 is nearly identical to its closest rivals, including the AMD Ryzen 7 6800HS, which has a delta of -0.3%, and the AMD Ryzen 7 PRO 5755GE, with a delta of 0.1%.

The CPU’s role in Rust is most apparent at 1080p with Low settings, where the system pushes 206.1 FPS. This high frame rate confirms the processor’s ability to handle the game’s simulation and entity update loops. However, the data shows that as resolution increases, the CPU’s influence wanes. The frame rate difference between 1080p Low and 1440p Low is 56.2 FPS, and between 1440p Low and 4K Low is 62.9 FPS. This scaling indicates that the GPU is becoming the limiting factor. The CPU’s 16 threads and high boost clock of 4.80 GHz ensure that it does not become a bottleneck at lower resolutions, but the RTX 3080’s pixel-pushing demands at 4K ultimately cap performance. The processor’s 105 W TDP and unlocked multiplier make it a capable partner for this GPU, but the measured data confirms that the graphics card is the component that dictates the frame rate ceiling in Rust at higher resolutions.
