Rust

Rust’s measured frame rates for the AMD Ryzen 5 5600GT and AMD Radeon RX 6800 XT combination reveal a clear and expected pattern: performance scales inversely with resolution, but the rate of decline is steeper than a purely GPU-bound scenario would suggest. At 1920x1080 with Low settings, the pair delivers 194.2 FPS on average. Moving to 2560x1440 drops that to 146.3 FPS, a reduction of roughly 25%. At 3840x2160, the average falls further to 87.6 FPS, which is about 55% lower than the 1080p figure. This scaling curve indicates that while the RX 6800 XT remains the dominant factor at higher resolutions, the CPU’s influence becomes more pronounced as pixel count decreases.

The gap between Low and Ultra settings widens dramatically with resolution. At 1080p, Low produces 194.2 FPS and Ultra yields 92.4 FPS, a difference of 101.8 FPS. At 1440p, that gap shrinks to 81.3 FPS (146.3 vs 65.0). At 4K, it narrows further to 50.7 FPS (87.6 vs 36.9). This compression suggests that at 4K, the GPU is nearing its capacity limit, and the CPU’s ability to feed frames becomes less critical. The data implies that for high-refresh 1080p monitors, the CPU is holding the system back from reaching its true ceiling, whereas 4K gaming shifts the bottleneck squarely onto the GPU.

Resolution Scaling

The measured FPS rows show a consistent hierarchy: Low settings always produce the highest average, followed by Medium, then High, with Ultra at the bottom. This ordering holds across all three resolutions, but the absolute differences tell the story of where the bottleneck lives. At 1920x1080, the spread from Low (194.2 FPS) to Ultra (92.4 FPS) is 101.8 FPS, indicating that the GPU has ample headroom and the CPU’s single-thread performance is likely the limiting factor. The Ryzen 5 5600GT’s single-thread benchmark score of 913 in 3dMark, alongside a PassMark single-thread score of 3348, suggests modest per-core throughput that can cap frame generation at lower resolutions.

At 2560x1440, the same settings spread produces a narrower range: Low at 146.3 FPS and Ultra at 65.0 FPS, a delta of 81.3 FPS. The relative drop from 1080p to 1440p is largest for Low settings (194.2 to 146.3, down 24.7%) and smallest for Ultra (92.4 to 65.0, down 29.6%). This indicates that higher quality presets are already stressing the GPU more uniformly, so the resolution change has a proportional impact. At 3840x2160, the range compresses further: Low hits 87.6 FPS, Medium 57.0, High 47.5, and Ultra 36.9. The delta between Low and Ultra is now just 50.7 FPS. This compression is a classic sign of a GPU-bound scenario, where the RX 6800 XT’s raw throughput dictates the frame rate regardless of CPU speed.

The data suggests that 1080p users of this combo will be CPU-limited, particularly on Low and Medium presets. The 5600GT’s 6 cores and 12 threads, with a boost clock of 4.60 GHz, are sufficient for most tasks, but Rust’s simulation logic and entity updates can be demanding. At 4K, the situation reverses: the GPU’s 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are being pushed hard, and the CPU’s role diminishes. The 4K Low score of 87.6 FPS is still playable, but the Ultra score of 36.9 FPS falls below smooth thresholds, suggesting that maxing out settings at 4K requires a more powerful GPU than what is present here.

GPU Role

The AMD Radeon RX 6800 XT is the centerpiece of this build, and its specifications align with the measured results. The GPU operates with a base clock of 1825 MHz and a boost clock of 2250 MHz, with a game clock of 2015 MHz. These clocks, combined with 4608 shading units and 128 ROPs, provide substantial fill rate and compute throughput. The GPU’s pixel rate is 288.0 GPixel/s, and its texture rate is 648.0 GTexel/s, which explains why High settings at 1440p can hold 79.3 FPS and Medium at 4K can reach 57.0 FPS.

Memory capacity and bandwidth are critical for Rust, which features large open-world maps and frequent asset streaming. The RX 6800 XT’s 16 GB of GDDR6 memory on a 256-bit bus delivers 512.0 GB/s of bandwidth. This is sufficient to avoid stutter at 4K, as evidenced by the 47.5 FPS average at High settings, which is still smoother than the 36.9 FPS at Ultra. The GPU’s FP32 throughput of 20.74 TFLOPS is a strong indicator of its ability to handle complex shading and lighting effects, but the measured data shows that Ultra presets at 4K push it past its comfort zone.

In benchmark terms, the RX 6800 XT scores 24980 in PassMark G3D and 13245 in PassMark GPU Compute. Its percentile vs all GPUs is 87, meaning it outperforms the vast majority of graphics cards. Among its nearest rivals, it sits 0.5% ahead of the Intel Arc A550M and 1.9% ahead of the NVIDIA CMP 50HX, but 1.7% behind the NVIDIA RTX A1000 and 2.6% ahead of the NVIDIA GeForce RTX 4070 Ti SUPER. These deltas are small, indicating that the RX 6800 XT is competitively positioned, though not a runaway leader. The 3dMark Steel Nomad DX12 score of 3689 reinforces its DirectX 12 capability, which is relevant for Rust’s modern rendering path.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture, built on a 7 nm process. Its base clock is 3.60 GHz with a boost clock of 4.60 GHz, and it has 16 MB of L3 cache. The CPU’s multi-threaded performance is solid for its class, with a Cinebench R23 multi-core score of 17272 and a PassMark multithread score of 20325. However, its single-thread performance is more modest, with a Cinebench R23 single-core score of 2438 and a Geekbench single-core score of 2035.

In Rust, the CPU’s role is to manage the game’s entity simulation, physics, and network code, which are often single-thread dependent. The measured FPS at 1080p Low (194.2) suggests that the CPU can push high frame rates, but the drop to 92.4 FPS at Ultra indicates that the GPU is also being taxed. The CPU’s percentile vs all CPUs is 78, placing it above average but not elite. Its nearest rival, the Intel Core i7-10700, scores 20746 in average benchmark, which is essentially identical to the 5600GT’s 20740, showing a delta of 0%. The AMD Ryzen 5 5600X is 0.3% faster, while the Intel Core i5-12490F is 0.3% slower. This means that in CPU-bound scenarios, the 5600GT performs on par with these alternatives.

The CPU’s 12 threads can help with background tasks, but Rust’s core loop often relies on fewer threads. The 3dMark 16-thread score of 5523 and max-thread score of 5554 indicate that scaling plateaus after 8 threads (score 4968), suggesting diminishing returns. For gaming, the 2-thread score of 1794 is more relevant, and it shows that the CPU can handle the primary game thread reasonably well. The 5600GT’s integrated Radeon Vega 7 graphics are irrelevant here since a discrete GPU is present, but they do not detract from performance.

Settings Recommendations

Based on the measured FPS rows, the optimal settings balance depends on the target resolution and refresh rate. At 1920x1080, Low settings deliver 194.2 FPS, which is ideal for high-refresh monitors, but Medium (138.3 FPS) offers a significant visual upgrade with only a 28.8% performance penalty. High settings at 116 FPS are still smooth for 120 Hz displays, while Ultra at 92.4 FPS is playable but may not fully utilize a 144 Hz panel. For most 1080p users, High is the sweet spot, providing a strong frame rate without sacrificing too much visual fidelity.

At 2560x1440, Low (146.3 FPS) is overkill for most 144 Hz monitors, and Medium (94.9 FPS) provides a better experience with improved textures and effects. High (79.3 FPS) is acceptable for 75 Hz or 100 Hz panels, but Ultra (65.0 FPS) dips below the 72 FPS threshold that many consider the minimum for smooth gameplay. The recommendation here is Medium or High, depending on whether the user prioritizes frame rate or image quality. Given that the GPU has 16 GB of VRAM, texture-heavy settings at Medium and High should not cause memory-related stutters.

At 3840x2160, the choices are more constrained. Low (87.6 FPS) is the only preset that reliably exceeds 60 FPS, while Medium (57.0 FPS) is just below that mark. High (47.5 FPS) and Ultra (36.9 FPS) are playable but not ideal for fast-paced action. For 4K gaming, the data suggests that Low or Medium is the practical choice, with Low offering a 53.7% performance advantage over Medium. Users with adaptive sync displays may tolerate High, but the 47.5 FPS average will show noticeable frame pacing issues in busy scenes.
