Rust

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6750 XT is a desktop combination aimed at 1080p and 1440p gaming. In Rust, the measured frame rates show how the balance between CPU and GPU shifts across resolution scales and preset levels. This analysis breaks down those numbers and what they imply about the system’s capabilities.

Resolution Scaling

The measured average FPS data reveals a consistent scaling pattern from 1920x1080 to 3840x2160. At 1920x1080, the Low preset averages 173 FPS, Medium 116 FPS, High 98 FPS, and Ultra 75 FPS. When the resolution jumps to 2560x1440, those averages fall to 119, 80, 68, and 51 FPS respectively—roughly 69% of the 1080p value across all presets. Moving to 3840x2160, the numbers drop further: Low 70, Medium 47, High 40, and Ultra 30. The 4K values are about 40% of the 1080p values, regardless of preset.

The uniformity of this drop is telling. The pixel count from 1080p to 4K increases fourfold, and the FPS falls to a near-constant 40% of the original. If the CPU were the limiting factor, we would expect a less severe drop because the CPU workload does not scale with resolution; it would be more likely to hold a consistent frame rate. Here, the FPS scales in near-lockstep with the GPU workload, which indicates that the GPU is the bottleneck at higher resolutions. The same pattern appears at 1440p, where the FPS retains about 69% of the 1080p figure—a drop that aligns with the 1.78x pixel difference. The GPU clearly determines the performance ceiling as resolution rises.

Within a given resolution, preset selection also scales predictably. At 1080p, moving from Low to Ultra cuts FPS from 173 to 75, a 43% reduction. At 4K, the same change reduces FPS from 70 to 30, also about 43%. The relative impact of presets is consistent across resolutions, again pointing to the GPU as the primary constraint rather than any CPU-side variable.

CPU Role

The CPU in this combo is the AMD Ryzen 5 5600G, built on the Zen 3 architecture. It has 6 cores and 12 threads, with base and boost clocks of 3.90 GHz and 4.40 GHz respectively. The L3 cache is 16 MB, and the TDP is 65 W. Synthetic tests show a Cinebench R23 multi-core score of 10551 and a single-core score of 1409. The CPU attains a 3DMark single-thread score of 872. These figures land it in the 74th percentile of all CPUs. Its nearest rivals in average score are the Intel Core i3-1220P, which scores 21066, and the AMD Ryzen 5 7530U at 21133—all within 0.4% of the 5600G.

Given those numbers, the workload at 1080p Low with 173 FPS is within the CPU's apparent input generation capacity. The 6-core/12-thread design, with a boost clock of 4.40 GHz, provides enough per-core performance to avoid being the primary bottleneck when the GPU is rendering at lower resolution. However, as resolution scales up, the GPU workload increases disproportionately, and the CPU stops being the constraining factor. For example, at 4K Ultra the FPS only reaches 30, while the CPU could still likely handle more frames if the GPU could deliver them. The data does not show any CPU-limited behavior—FPS rescaled directly with GPU load, so the CPU is not a limiting performance component even at 1080p High regards the very high 173 FPS at Low.

GPU Role

The AMD Radeon RX 6750 XT uses the Navi 22 RDNA 2 architecture, with 2560 shading units, a 160 TMU and 64 ROPs. It has a base clock of 2150 MHz and a boost clock of 2600 MHz. Memory is 12 GB of DDRGD6, connected via a 192-bit bus with a bandwidth of 432.0 GB/s. Its benchmark performance is defined by a PassMark G3D score of 20700 and a percentile of 71. The closest competitor in the database is the AMD Radeon R9 M395X, which is 0.5% slower, and the NVIDIA GeForce RTX 3080 Ti Mobile is 1.1% faster—so the 6750 XT represents a midrange tier of graphics.

The GPU's dominance in limiting Rust's frame rate becomes evident when looking at the 4K results. At 4K Low, the average is 70 FPS; at Ultra, it is 30 FPS. The fact that even the Low preset only produces 70 FPS—while the same preset at 1080p produces 173 FPS—demonstrates that the GPU render has reached its capacity. In VRAM is not the limiting factor at 12 GB at those resolutions, but the shading power and memory bandwidth appear to saturate. The 432 GB/s bandwidth and 2560 shaders clearly cannot keep up with the increased pixel count. Consequently, when comparing the performance at the same preset across resolutions, the GPU is the component that sets the final frame rate.

How This Combo Ranks

The overall combination of the Ryzen 5 5600G and RX 6750 XT is cataloged in a composite rank 1700 out of 3723 measured desktop combinations. This places the combo in a percentile of approximately the 54th percentile, meaning 54% of tested configurations are slower. The CPU itself is above average (74th percentile) and the GPU is slightly below that (71st percentile), yet the combined rank dips below the 50% mark? Actually it is above the median—since 3723 - 1700 = 2023, it is better than 54.3% of the tested combos. So it sits just above the center.

The gap between the individual part percentiles and the combined rank suggests that the synergy is not optimal. The CPU is capable of feeding the GPU at lower resolutions, but at high resolutions the GPU becomes the end factor, and the CPU's extra headroom never becomes a benefit. In absolute terms, this combo outperforms roughly half of all the combos tested in Rust, but its weakness lies in the GPU under 4K workloads.

FAQ

Q: What average frame rate does this combo achieve at 1920x1080 with High settings?

A: 98 FPS on average. The Medium preset produces 116 FPS, while Low achieves 173 FPS and Ultra 75 FPS.

Q: Is this combination suitable for 4K gaming in Rust?

A: At 3840x2160, the Low preset yields 70 FPS, Medium 47 FPS, High 40 FPS, and Ultra 30 FPS. Only the Low preset delivers a frame rate that exceeds 60 FPS; the rest are below 50 FPS, so 4K gaming is borderline and best left to the lowest settings.

Q: How does the CPU’s benchmark score compare to its closest rivals?

A: The Ryzen 5 5600G averages 21088, while the Intel Core i3-1220P scores 21066 (0.1% higher) and the Intel Core Ultra 7 256V scores 21112 (0.1% lower). The results are nearly identical.

Q: How does the GPU compared to the nearest competitors?

A: The RX 6750 XT has an average benchmark score of 26011, which is only 0.5% higher than the Radeon R9 M395X and 1.1% higher than the RTX 3080 Ti Mobile. The measured frame rates are consistent with its rating.

Q: What is the most balanced preset at 2560x1440?

A: At 1440p, the Medium preset has an average of 80 FPS, with Low at 119 FPS and High at 68 FPS. Extra Ultra drops to 51 FPS. Medium provides a high average with decent quality, while staying above the 60 FPS mark. High still exceeds the 60 FPS threshold.

Settings Recommendations

Based on the measured frame rates, a few guidelines emerge. For 1920x1080 displays, the High preset (98 FPS) offers a clear step above Medium (116 FPS) but still keeps almost triple-digit performance, while Ultra (75 FPS) is acceptable on a 144Hz monitor only if you prioritise visuals over smoothness. At 2560x1440, Medium (80 FPS) is the best combination of quality and performance—would give High (68 FPS) a slight edge on visual fidelity, but the difference is not huge. The Ultra preset (51 FPS) drops below the 60 FPS threshold. For 3840x2160, only the Low preset (70 FPS) produces enough of a headroom to be playable—Medium (47 FPS) and everything else falls off the -60Hz target. Therefore, the “Low” preset is the only sensible choice for 4K in Rust on this pair.

The Medium presets list min and max FPS, showing a narrow span (99–134, 68–92, and 40–54) that reinforces stable performance. The lack of such data for other presets means the average is the sole metric for those, but the consistent across all presets suggests the GPU allocation. The measured frame rates confirm the CPU is not a limiting factor at any resolution, and the GPU’s capacity is the deciding element as pixel count increases. The 5600G and 6750XT pair delivers solid gameplay in the 1080p and 1440p, but the 4K Ultra preset will require a more powerful GPU for consistent high refresh.
