Resolution Scaling

Rust's frame rate behavior across resolutions tells a clear story about where the bottleneck sits with this AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 4080 SUPER pairing. At 1920x1080 with Low settings, the combo produces 177.2 FPS. Moving to 2560x1440 Low drops that to 153 FPS, a 13.7% reduction. At 4K Low, the average falls to 117.3 FPS, which represents a 33.8% drop from the 1080p Low result. This scaling pattern suggests that even at Low settings, the GPU begins to assert its influence as pixel count rises, though the CPU's large 96 MB shared L3 cache keeps frame pacing consistent.

The High preset tells a similar but steeper story. At 1080p High, the system delivers 141.3 FPS. At 1440p High, it falls to 111.8 FPS, a 20.9% decline. At 4K High, the average lands at 66.1 FPS, which is a 53.2% drop from 1080p High. This steeper curve indicates that the RTX 4080 SUPER's 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are being taxed more heavily as resolution climbs, with the 4K High result approaching the threshold where visual fidelity starts to compromise fluidity.

Ultra settings amplify the resolution sensitivity further. The 1080p Ultra average is 125.9 FPS, while 1440p Ultra drops to 84.1 FPS, a 33.2% reduction. At 4K Ultra, the system manages just 47.6 FPS, a 62.2% decline from 1080p Ultra. This dramatic falloff at 4K Ultra indicates that the GPU's 52.22 TFLOPS FP32 compute and 816.0 GTexel/s texture rate are saturated by Rust's highest preset combined with the 3840x2160 pixel workload.

The Medium preset shows the most linear scaling. From 148.8 FPS at 1080p, the 1440p Medium result of 134.7 FPS represents a 9.5% drop, while 4K Medium reaches 75.9 FPS, a 49.0% reduction from 1080p Medium. The data indicates that Rust's performance ceiling at 1080p is primarily CPU-bound, given the 5700X3D's 3.00 GHz base and 4.10 GHz boost clocks with 8 cores and 16 threads. At 4K, the GPU becomes the dominant limiting factor across all presets.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER plays a decisive role in Rust's higher-resolution and higher-preset results. Its 16 GB of GDDR6X memory across a 256-bit bus provides 736.3 GB/s of bandwidth, which is essential for Rust's large, persistent world data and texture streaming. The GPU's 10240 shading units and 112 ROPs deliver the pixel throughput needed for 4K rendering, as evidenced by the 66.1 FPS High result at 3840x2160.

Clock behavior matters here. The GPU's base clock of 2295 MHz and boost of 2550 MHz are modestly high, but the memory clock of 1438 MHz (23 Gbps effective) is where the bandwidth story unfolds. At 4K Ultra, the 47.6 FPS average suggests the GPU's compute resources are fully engaged, with the 52.22 TFLOPS FP32 throughput being the limiting factor rather than memory bandwidth. The 3DMark Steel Nomad DX12 score of 6600 and PassMark G3D score of 34245 place this GPU in the 88th percentile among all GPUs, confirming its high-end positioning.

The GPU's nearest rivals show close competition. The AMD Radeon RX 6900 XT scores 53489 on average, just 0.2% behind the RTX 4080 SUPER's 53610 average. The AMD Radeon Pro W6600M is 0.4% behind, while the AMD Radeon RX 7700S trails by 2.1%. The NVIDIA GeForce RTX 5070 Ti is 2.9% behind in average benchmark score, indicating that the 4080 SUPER remains competitive even against newer silicon.

Rust's measured results show that the RTX 4080 SUPER can push 177.2 FPS at 1080p Low, but the 4K Ultra result of 47.6 FPS reveals that the GPU's 80 RT cores and 320 tensor cores do not directly accelerate Rust's rasterization workload. The PassMark DirectX 12 score of 134 and DirectX 11 score of 301 suggest that Rust's API utilization is not fully optimized for the Ada Lovelace architecture's strengths, which partially explains why 4K Ultra falls below 60 FPS.
