CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor built on the Zen 3 (Vermeer) architecture using TSMC's 7 nm process. It operates with a base clock of 3.80 GHz and a boost clock of 4.80 GHz, which are critical figures for Rust's performance profile. The CPU's 32 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are relevant factors for a game that frequently loads and unloads large world data as players traverse the map.

In synthetic benchmarks, the 5800XT demonstrates strong multi-threaded capability with a Cinebench R23 multicore score of 23794 and a single-core score of 3359. The 3DMark results show a scaling pattern from 959 in single-thread to 7683 in the 16-thread test, indicating that the processor efficiently utilizes additional threads. The PassMark multithread score of 27988 and single-thread score of 3538 place this CPU at the 86th percentile among all CPUs, meaning it outperforms the vast majority of installed processors.

Looking at the measured FPS data, the 5800XT's role becomes clear when examining the 1080p Low preset performance. At 1920x1080 with Low settings, the system achieves 205.5 FPS average. This high frame rate at a resolution where the GPU has less work to do suggests that the CPU is capable of feeding frames quickly. However, the gap between Low and Ultra at 1080p is substantial—from 205.5 FPS down to 105.7 FPS—which indicates that as graphical settings increase, the workload shifts toward the GPU, but the CPU still maintains a solid baseline.

The nearest rivals for this CPU include the AMD Ryzen 7 6800HS with an average score of 29856 (0.3% higher) and the AMD Ryzen 7 7840H at 29868 (0.3% higher). The 5800XT sits essentially at parity with these mobile-oriented parts in average benchmark score, with a deltaPct of only -0.3% against both. This means that despite being a desktop processor with a 105 W TDP, its computational throughput is comparable to efficient mobile chips, which is noteworthy given Rust's tendency to be CPU-bound in complex scenes with many entities.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 SUPER is built on the Ada Lovelace architecture using TSMC's 5 nm process. It features 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of memory bandwidth. The GPU operates with a base clock of 1980 MHz and a boost clock of 2475 MHz, with memory running at 1313 MHz (21 Gbps effective). These specifications are directly relevant to Rust's rendering demands, particularly at higher resolutions where texture memory and bandwidth become limiting factors.

The GPU's compute capabilities include 7168 shading units, 224 texture mapping units, and 80 raster output units. With 56 RT cores and 224 tensor cores, the RTX 4070 SUPER offers 35.48 TFLOPS of FP32 performance. In synthetic benchmarks, the GPU achieves a PassMark G3D score of 29995 and a Geekbench OpenCL score of 192684. The 3DMark Steel Nomad DX12 score of 4627 places this GPU at the 84th percentile among all GPUs.

The measured FPS data reveals how the GPU's characteristics affect Rust performance. At 4K Ultra settings, the system manages only 44.4 FPS average, which is below the threshold for smooth gameplay on many displays. This represents a significant drop from the 4K Low result of 100.9 FPS. The 12 GB VRAM capacity is sufficient for Rust at these settings, but the 192-bit memory bus and 504.2 GB/s bandwidth become more stressed as resolution increases, since the game must stream more texture data per frame.

Comparing to its nearest rivals, the RTX 4070 SUPER has an average benchmark score of 42576, which is nearly identical to the NVIDIA RTX A6000 at 42653 (a deltaPct of -0.2%). The AMD Radeon RX 7650 GRE scores 42723, putting it 0.3% ahead, while the AMD Radeon Pro 580X trails slightly at 41991 (1.4% behind). These small deltas indicate that the RTX 4070 SUPER is positioned in a dense performance cluster, but the game-specific results show how Rust's particular engine characteristics can amplify or diminish these differences.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS data provides clear guidance on which settings preset offers the optimal balance between visual quality and frame rate for Rust on this hardware combination. At 1920x1080, the Medium preset delivers 170.2 FPS average, which is only 35.3 FPS lower than Low (205.5 FPS) but represents a significant visual improvement. The High preset at 1080p produces 142.6 FPS, still comfortably above the 60 FPS threshold for most monitors, while Ultra drops to 105.7 FPS.

For 2560x1440, the Medium preset achieves 118.3 FPS, which is an excellent result for a 1440p display. High at this resolution produces 97.4 FPS, still suitable for high-refresh-rate gaming, while Ultra falls to 71.7 FPS. Low at 1440p reaches 171.5 FPS, but the visual sacrifices may not be worth the extra frame rate when Medium is already well above refresh rate capabilities of most monitors.

At 3840x2160, the situation changes dramatically. Medium produces 69.5 FPS, which is playable but not ideal for competitive scenarios. High drops to 58 FPS, and Ultra falls to 44.4 FPS, which is noticeably below the 60 FPS target. Low at 4K achieves 100.9 FPS, but the visual quality at Low settings on a 4K display would be significantly degraded.

The data suggests that Medium is the sweet spot for this combination across all resolutions. At 1080p, Medium provides ample headroom above 144 Hz refresh rates; at 1440p, it remains above 100 FPS; and at 4K, it stays above the 60 FPS threshold. The frame rate scaling from Medium to High is consistent—a drop of approximately 27-28 FPS at 1080p and 1440p, and 11.5 FPS at 4K—suggesting that the graphical fidelity gains from High may not justify the performance cost for most users.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals important information about which component is limiting performance in Rust. At Low settings, the frame rate drops from 205.5 FPS at 1080p to 171.5 FPS at 1440p (a 16.5% decrease) and further to 100.9 FPS at 4K (a 50.9% decrease from 1080p). This pattern shows that even at Low settings, the GPU becomes progressively more stressed as resolution increases, but the CPU still manages to maintain relatively high frame rates.

At Medium settings, the scaling is more pronounced: 170.2 FPS at 1080p drops to 118.3 FPS at 1440p (30.5% decrease) and 69.5 FPS at 4K (59.2% decrease from 1080p). The larger percentage drops at Medium compared to Low suggest that the GPU's rendering workload is scaling more aggressively with resolution when more visual effects are enabled.

The High settings show similar trends: 142.6 FPS at 1080p, 97.4 FPS at 1440p (31.7% decrease), and 58 FPS at 4K (59.3% decrease). Ultra settings follow the same pattern with 105.7 FPS, 71.7 FPS, and 44.4 FPS respectively, representing a 58% decrease from 1080p to 4K.

The fact that the percentage drop from 1080p to 4K is consistent (roughly 50-59%) across all settings indicates that the GPU is the primary limiting factor at higher resolutions. If the CPU were the bottleneck, we would expect to see smaller frame rate drops at higher resolutions, since the GPU would have more time to render each frame while waiting for CPU data. The consistent scaling pattern suggests that the RTX 4070 SUPER's 12 GB VRAM and 504.2 GB/s bandwidth are being progressively saturated as pixel count increases.

However, the 1080p results indicate that the CPU can still be a factor. The difference between Low (205.5 FPS) and Medium (170.2 FPS) at 1080p is only 35.3 FPS, while the difference between Medium and High is 27.6 FPS. This suggests that at 1080p, the CPU can keep up with the GPU's frame production, but the GPU's performance ceiling is reached around the 200 FPS mark with this processor.
