Rust

The AMD Ryzen 7 9700F and NVIDIA GeForce RTX 5080 combination delivers a performance profile in Rust that is heavily dictated by resolution, with the GPU becoming the primary bottleneck at 4K while the CPU's strength is exposed at 1080p. This pairing ranks in the 97th percentile of all tested combinations, placing it firmly in the top tier for this survival title, though the data reveals that its dominance is not uniform across all settings.

Resolution Scaling

The measured FPS data shows a dramatic and consistent drop as resolution increases from 1080p to 4K, a pattern that clearly identifies the RTX 5080 as the limiting component at higher resolutions. At 1080p with Low settings, the combo achieves an average of 276 FPS, which falls to 205 FPS at 1440p and then drops to 121 FPS at 4K. This represents a 56% reduction in performance from 1080p to 4K, a scaling curve that is characteristic of a GPU-bound scenario where the rendering load on the graphics card quadruples.

The scaling behavior changes when moving to higher quality presets, which indicates a shift in the balance of the bottleneck. At Ultra settings, the frame rates are 129 FPS at 1080p, 88 FPS at 1440p, and 52 FPS at 4K. The performance drop from 1080p to 4K at Ultra is 60%, which is steeper than the Low preset's 56% decline. This suggests that the Ultra preset's additional graphical effects, such as advanced shading and post-processing, place a proportionally larger burden on the GPU, making the 4K Ultra experience particularly demanding.

The Medium preset provides the most revealing data on the scaling curve, as it includes both minimum and maximum FPS values. At 1080p Medium, the average is 200 FPS with a range from 170 to 230 FPS. At 1440p Medium, the average drops to 138 FPS with a range of 117 to 158 FPS, and at 4K Medium, the average is 81 FPS with a range of 69 to 94 FPS. The consistency of the frame delivery, as indicated by the narrow spread between minimum and maximum, suggests that the RTX 5080 is maintaining stable performance without significant stuttering, even as the resolution increases.

The fact that 4K Low (121 FPS) outperforms 1080p Ultra (129 FPS) by a small margin is notable. This indicates that the CPU is capable of feeding the GPU enough data at 1080p Ultra, but the GPU's raw throughput is not the sole determinant of performance at that setting. The 4K Low result being so close to the 1080p Ultra result implies that the game's engine is more sensitive to certain graphical features than to raw pixel count, making the resolution scaling less predictable than a pure pixel-count analysis would suggest.

GPU Role

The NVIDIA GeForce RTX 5080 features 16 GB of GDDR7 memory on a 256-bit bus, providing a memory bandwidth of 960.0 GB/s. This high bandwidth is critical for Rust, which often loads large texture sets and world data into VRAM. The 16 GB capacity is substantial, allowing the GPU to hold high-resolution textures at 4K without resorting to slower system memory.

The GPU's clock speeds are a base of 2295 MHz and a boost of 2617 MHz. The boost clock is the more relevant figure for gaming performance, as the GPU will automatically raise its clock speed under load to the maximum sustainable level. The RTX 5080's architecture, Blackwell 2.0, is built on a 5 nm process at TSMC, with 45,600 million transistors on a 378 mm² die.

The benchmark data for the GPU shows a Passmark G3D score of 36,565 and a Passmark GPU Compute score of 21,789. These scores place it in the 87th percentile of all GPUs. In Rust specifically, the GPU's role becomes more pronounced at higher resolutions. The scaling from 1080p to 4K at Low settings (276 to 121 FPS) shows a 56% drop, which is less than the 60% drop seen at Ultra settings (129 to 52 FPS). This indicates that the GPU's rendering capabilities are the primary limiter at 4K Ultra.

The RTX 5080's performance in Rust is also affected by the game's settings. The difference between Low and Ultra at the same resolution is significant. At 1080p, the gap is 147 FPS (276 vs 129). At 1440p, the gap is 117 FPS (205 vs 88). At 4K, the gap is 69 FPS (121 vs 52). This consistent gap across resolutions suggests that the Ultra preset adds a fixed computational cost that scales with resolution.

CPU Role

The AMD Ryzen 7 9700F is an 8-core, 16-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It has a base clock of 3.80 GHz and a boost clock of 5.50 GHz. The CPU has a 32 MB shared L3 cache and 1 MB of L2 cache per core, which is essential for maintaining high instruction throughput in Rust's complex simulation loops.

The CPU's Passmark scores show a multithread score of 36,470 and a single-thread score of 4,691. The single-thread score is particularly important for Rust, as the game's core simulation loop is often constrained by single-threaded performance. The CPU's percentile rank of 94 indicates that it outperforms the vast majority of processors available, and its nearest rivals are all high-end desktop and mobile parts.

The CPU's TDP is 65 W, which is low for a processor with this level of performance. This efficiency allows it to maintain high boost clocks without thermal throttling, which is critical for sustained gaming sessions. The 9700F supports DDR5 memory with a dual-channel bus and a bandwidth of 89.6 GB/s, providing the memory bandwidth necessary to feed the CPU's 8 cores.

In Rust, the CPU's role is most evident at 1080p, where the GPU is not fully saturated. At 1080p Low, the 276 FPS average demonstrates that the CPU can process the game's logic fast enough to allow the GPU to render at very high frame rates. The fact that 1080p Ultra (129 FPS) is only slightly higher than 4K Low (121 FPS) suggests that the CPU is the limiting factor at 1080p Ultra, as the GPU has more headroom at that resolution. The CPU's strong single-thread performance, as evidenced by its 4,691 Passmark score, is the key enabler for this level of performance.
