Rust

The AMD Ryzen 5 4600G paired with the AMD Radeon RX 6750 XT delivers a highly playable Rust experience, but the data reveals a clear pattern: this combo is a 1080p and 1440p champion that struggles to maintain smooth frame rates at 4K. The measured results show a steep performance cliff as resolution increases, with the gap between settings presets widening dramatically. This analysis breaks down the exact numbers, explains what they mean for your build, and offers practical settings advice based solely on the measured data.

Resolution Scaling

The FPS drop from 1080p to 4K is severe and consistent across all settings presets. At Low settings, the average frame rate falls from 153.1 FPS at 1920x1080 to 69.3 FPS at 3840x2160 — a loss of 83.8 FPS, or roughly 55% of the 1080p performance. The scaling is even more punishing at Ultra, where the 1080p average of 78 FPS craters to 29.7 FPS at 4K, a drop of 48.3 FPS that takes the experience from smooth to nearly unplayable.

The limiting component shifts as resolution climbs. At 1080p, the gap between Low and Ultra is 75.1 FPS (153.1 vs 78), which suggests the CPU is keeping up reasonably well while the GPU has headroom. By 4K, that same Low-to-Ultra gap shrinks to 39.6 FPS (69.3 vs 29.7), indicating the GPU is now the primary bottleneck. The RX 6750 XT’s 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are sufficient for 1440p, but the pixel throughput demands of 4K overwhelm the card’s 166.4 GPixel/s pixel rate.

The 1440p results sit in a comfortable middle ground. At High settings, the average is 69.8 FPS, nearly identical to the 4K Low result of 69.3 FPS. This suggests that 1440p High is roughly equivalent to 4K Low in terms of GPU load, which makes sense given the resolution difference. For gamers targeting 60 FPS, 1440p is the sweet spot — even Ultra manages 53 FPS, which is close to playable, while dropping to Medium or High secures a solid margin above the 60 FPS threshold.

Settings Recommendations

For 1920x1080, the data strongly favors Medium or High presets. Low settings deliver 153.1 FPS, which is excessive for most displays, and the jump to Medium only costs 34.7 FPS while likely improving visual fidelity significantly. High settings at 97.8 FPS still provide excellent headroom above 60 FPS, making it the best balance for competitive play where visual clarity matters. Ultra at 78 FPS is perfectly playable, but the 19.8 FPS penalty over High may not justify the visual gains.

At 2560x1440, Medium is the recommended starting point. The 80 FPS average gives a comfortable margin above 60 FPS, and High’s 69.8 FPS is still smooth but leaves less room for frame drops during intense moments. Ultra at 53 FPS is borderline — it will feel stuttery in fast-paced combat, so only choose it if you prioritize visuals over responsiveness. Low at 120.5 FPS is overkill for most 1440p monitors, so it’s not necessary unless you have a high-refresh display.

For 3840x2160, the data paints a grim picture. Even Low settings only manage 69.3 FPS, which is technically playable but leaves no headroom. Medium drops to 48.2 FPS, High to 40.9 FPS, and Ultra to 29.7 FPS — all below the 60 FPS threshold that most players consider minimum for smooth gameplay. The recommendation here is simple: avoid 4K with this combo unless you are willing to accept Low settings and frame rates in the 60s, or use a lower resolution and upscale.

FAQ

Q: Can this combo run Rust at 60 FPS on a 1440p monitor?

A: Yes, comfortably. At 2560x1440, Medium settings produce 80 FPS, High produces 69.8 FPS, and even Ultra hits 53 FPS. The data shows that Medium or High are the best choices to maintain a stable 60+ FPS experience.

Q: What is the best settings preset for 1080p competitive play?

A: High settings at 97.8 FPS offer the best combination of visual clarity and performance. Low settings hit 153.1 FPS, but the visual downgrade is unnecessary since High still leaves nearly 40 FPS of headroom above 60 FPS.

Q: Is 4K gaming viable with this hardware?

A: Barely, and only at Low settings, which averages 69.3 FPS. Medium drops to 48.2 FPS, High to 40.9 FPS, and Ultra to 29.7 FPS. For a consistent 60 FPS experience, 1440p is the realistic ceiling for this combo.

Q: How does the CPU affect performance in Rust?

A: The Ryzen 5 4600G has 6 cores and 12 threads with a boost clock of 4.20 GHz. Its benchmark scores, such as 13593 in Cinebench R23 multicore and 1919 in single-core, indicate it is capable of feeding the GPU at 1080p, where the Low-to-Ultra spread is large. At 4K, the GPU becomes the limiting factor, not the CPU.

Q: What frame rate can I expect at 1080p Ultra?

A: The measured average is 78 FPS. This is above 60 FPS but leaves less headroom than High (97.8 FPS) or Medium (118.4 FPS). If you experience drops in busy areas, dropping to High is the safer choice.

Q: How does this combo rank against other tested configurations?

A: The combo ranks 848th out of 1717 tested combos in Rust, placing it in the middle of the pack. This is consistent with the GPU’s 79th percentile ranking among all GPUs, while the CPU sits at the 75th percentile.

Measured FPS Breakdown

At 1920x1080, the results are as follows: Low averages 153.1 FPS, Medium 118.4 FPS, High 97.8 FPS, and Ultra 78 FPS. The scaling between presets is roughly linear, with each step up from Low costing about 25-30 FPS. This indicates the GPU has ample headroom at this resolution, and the CPU is not a limiting factor.

At 2560x1440, the numbers compress: Low hits 120.5 FPS, Medium 80 FPS, High 69.8 FPS, and Ultra 53 FPS. The drop from Low to Medium is 40.5 FPS, which is steeper than at 1080p, signaling that the GPU is starting to feel the load. The gap between High and Ultra narrows to 16.8 FPS, suggesting diminishing returns at the highest preset.

At 3840x2160, the performance collapses: Low averages 69.3 FPS, Medium 48.2 FPS, High 40.9 FPS, and Ultra 29.7 FPS. The Low-to-Medium drop is 21.1 FPS, and the High-to-Ultra drop is 11.2 FPS. No preset reaches 70 FPS, and only Low clears the 60 FPS threshold. The GPU’s 13.31 TFLOPS of FP32 performance is simply insufficient for 4K at high settings in Rust.

How This Combo Ranks

In the database of tested combinations, this CPU-GPU pairing ranks 848th out of 1717 combos in Rust, placing it almost exactly in the middle (49.4th percentile). This is a fair reflection of its capabilities: the RX 6750 XT is a strong mid-range card, ranking in the 79th percentile among all GPUs, but it is paired with a CPU that sits at the 75th percentile among all CPUs. The combination is balanced, but neither component is top-tier.

The GPU’s nearest rivals include the AMD Radeon RX 5600M (0.2% faster), the NVIDIA GeForce RTX 5070 Ti Mobile (0.3% slower), the AMD Radeon 880M (0.9% slower), and the NVIDIA GeForce RTX 3080 (1.3% slower). This places the RX 6750 XT in a tight cluster of performance, meaning the 848th rank is more about the CPU pairing than the GPU alone. The CPU’s rivals — the AMD Ryzen 3 PRO 5355GE (0% difference), Intel Core i5-12450H (0.1% faster), Intel Core i3-14100T (0.8% faster), and Intel Core i3-13100F (1% faster) — all offer similar compute performance, confirming that the 4600G is a solid but not exceptional partner.

The rank of 848 out of 1717 suggests that many other combos outperform this one in Rust, likely due to stronger CPUs or GPUs. However, the measured FPS data shows that the combo is more than adequate for 1080p and 1440p gaming, which is where most players will use it.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture (codename Renoir), built on a 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. Its cache layout includes 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. This is a modest amount of L3 by modern standards, which can impact gaming performance in titles that are sensitive to cache size, but Rust appears to handle it adequately based on the measured results.

The CPU’s benchmark scores are telling: a single-thread score of 726 in 3DMark and 1919 in Cinebench R23 indicate decent but not stellar single-core performance. Multi-thread scores are stronger, with 13593 in Cinebench R23 and 15992 in Passmark multithread. Rust is known to be CPU-intensive, particularly in large bases or crowded servers, but the 4600G’s 12 threads provide enough parallel processing headroom. The 51.2 GB/s memory bandwidth, paired with dual-channel DDR4 support, is sufficient to feed the GPU without creating a bottleneck at 1080p and 1440p.

At 1080p, the CPU is clearly not the limiting factor — the large FPS spread between Low and Ultra (75.1 FPS) shows the GPU is doing most of the work. At 4K, the CPU’s role diminishes further, as the GPU is overwhelmed by pixel count. The 4600G’s 4.20 GHz boost clock is adequate for Rust’s physics and entity update loops, but it is not a high-end gaming CPU. The data suggests that upgrading the CPU would yield marginal gains at 1080p but would not help at 4K, where the GPU is the bottleneck. For this combo, the CPU is a capable companion that does not hold the GPU back in most scenarios.
