Rust

The AMD Ryzen 7 5700G paired with the AMD Radeon RX 7800 XT delivers a wide spread of frame rates in Rust, but the shape of those results reveals a system that is heavily influenced by both the graphics card and the CPU’s older platform. The benchmark data shows a clear pattern: at 1080p the combination can push well past 190 FPS on Low settings, yet at 4K Ultra it drops to just 34 FPS. That massive swing is not merely a matter of resolution; it points to where the bottleneck shifts as the workload changes.

Resolution Scaling

The measured FPS data shows a steep decline as resolution rises, which is typical for a GPU-bound scenario, but the magnitude of the drop is worth examining. At 1080p Low, the system averages 193.1 FPS, while at 4K Low it falls to 84.2 FPS. That is a 56.4% reduction in frame rate from 1080p to 4K at the same settings, indicating that the RX 7800 XT is doing substantially more work at higher pixel counts. The pattern holds across all settings: 1080p Medium at 136.5 FPS drops to 4K Medium at 53.9 FPS, and 1080p High at 112.6 FPS falls to 4K High at 48.2 FPS.

Interpretation of these numbers suggests that at 1080p, the CPU has enough headroom to feed the GPU, but the GPU is still the primary limiter when settings are cranked up. The most telling comparison is between Low and Ultra at each resolution. At 1080p, the gap between Low (193.1 FPS) and Ultra (87.3 FPS) is 105.8 FPS, a 54.8% drop. At 4K, the same settings gap is from 84.2 FPS down to 34 FPS, a 59.6% drop. The percentage loss is similar, but the absolute numbers show that 4K Ultra is barely playable, while 1080p Low is exceptionally smooth.

The data implies that the limiting component changes with resolution. At 1080p Low, the CPU’s single-thread performance (3dmark_single_thread score of 899) likely becomes more relevant, but the high frame rates suggest it is still keeping up. At 4K Ultra, the GPU’s raw throughput (fp32 of 37.32 TFLOPS) is clearly stretched, as the frame rate drops to a level where the game becomes difficult to play smoothly. The scaling from 1440p to 4K is particularly harsh: 1440p High at 81.8 FPS drops to 4K High at 48.2 FPS, a 41.1% reduction, which is a larger proportional loss than from 1080p to 1440p at the same settings (112.6 to 81.8 FPS, a 27.4% drop). This suggests that 4K is where the GPU’s memory bandwidth of 624.1 GB/s and pixel rate of 233.3 GPixel/s become critical constraints.

GPU Role

The AMD Radeon RX 7800 XT is a substantial piece of hardware, with 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. Its boost clock is rated at 2430 MHz, with a game clock of 2124 MHz. These specifications directly influence the measured results. The 16 GB capacity is ample for Rust at any resolution tested, meaning that VRAM is unlikely to be the limiting factor in these runs. Instead, the memory bandwidth and the GPU’s compute capabilities (37.32 TFLOPS FP32) are what determine how quickly frames can be rendered.

The data shows that the GPU’s role becomes more pronounced as settings increase. At 1080p Low, the frame rate of 193.1 FPS is high enough that the GPU is probably not fully saturated, but at 4K Ultra (34 FPS), the GPU is clearly the dominant constraint. The RX 7800 XT’s percentileVsAllGpus of 76 indicates it sits above most GPUs in the benchmark database, yet the 4K Ultra result is still low. This suggests that Rust at Ultra settings is extremely demanding, likely due to heavy shading and post-processing effects that tax the GPU’s 3840 shading units and 60 RT cores, even if ray tracing is not explicitly measured here.

Comparing to its nearest rivals from the database, the RX 7800 XT has an avgBenchmarkScore of 32619, which is 0.2% higher than the AMD FirePro S9300 X2 (32540) and 0.4% higher than the NVIDIA P104-100 (32747, but with a negative deltaPct of -0.4, meaning the RX 7800 XT is slightly lower). These are close scores, indicating that the GPU is in a competitive tier, but the measured FPS in Rust shows that real-world performance can diverge from synthetic averages. The GPU’s passmark_g3d score of 24176 reinforces its mid-to-high range positioning, but the game’s specific engine quirks, such as its reliance on draw calls and object density, may not be captured by those synthetic tests.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of the Ryzen 7 5700G and RX 7800 XT ranks 592 out of 1717 combos. That places it in the upper third (roughly 34.5% of all combos are faster), which is a respectable position given the CPU is from the older 5000 series with a 65 W TDP. The comboRankInGame of 592 suggests that while the GPU is strong, the CPU may be holding back the overall result in some scenarios.

The CPU’s own benchmarks show it is a capable processor: its 3dmark_max_threads score of 6627 and cinebench_r23_multicore score of 20755 are solid for a Zen 3 chip. However, its nearest rivals in the CPU database include the AMD Ryzen 7 6800U (avgScore 25706, deltaPct -0.3) and the Intel Xeon D-2752TER (avgScore 25532, deltaPct 0.4). These are close scores, but the 5700G’s avgBenchmarkScore of 25626 is not far off. The CPU’s percentileVsAllCpus of 83 means it outperforms 83% of all CPUs in the database, which is strong, but the combination ranking of 592 out of 1717 implies that many other CPU-GPU pairings achieve better results in Rust specifically.

The rank implies that the GPU is doing most of the heavy lifting, but the CPU’s PCIe Gen 3 interface (16 lanes) could be a subtle bottleneck compared to newer platforms with PCIe Gen 4 or 5. The motherboard socket is AM4, which limits the CPU to DDR4 memory (dual-channel, 51.2 GB/s bandwidth), and that memory bandwidth is modest by modern standards. In a game like Rust, which is known for complex world simulations and frequent data streaming, the CPU’s 16 MB of L3 cache and 8 cores might be sufficient, but the memory bandwidth could be a limiting factor at high frame rates.

Measured FPS Breakdown

The full set of measured FPS values provides a complete picture. At 1920x1080, the results are: Low at 193.1 FPS, Medium at 136.5 FPS, High at 112.6 FPS, and Ultra at 87.3 FPS. These numbers show a clear progression: dropping from Low to Medium costs 56.6 FPS (29.3% reduction), from Medium to High costs 23.9 FPS (17.5% reduction), and from High to Ultra costs 25.3 FPS (22.5% reduction). The largest single-step loss is from Low to Medium, which suggests that the medium preset introduces significant visual effects that heavily impact performance.

At 2560x1440, the data is: Low at 140.7 FPS, Medium at 96.2 FPS, High at 81.8 FPS, and Ultra at 59.4 FPS. The relative drops are similar to 1080p: Low to Medium is a 31.6% reduction (44.5 FPS), Medium to High is 15.0% (14.4 FPS), and High to Ultra is 27.4% (22.4 FPS). The Ultra preset at 1440p is still above 60 FPS, which is a playable threshold, but the 4K results are where the system struggles.

At 3840x2160, the values are: Low at 84.2 FPS, Medium at 53.9 FPS, High at 48.2 FPS, and Ultra at 34 FPS. Here, the drops are more severe in absolute terms: Low to Medium is a 36.0% reduction (30.3 FPS), Medium to High is 10.6% (5.7 FPS), and High to Ultra is 29.5% (14.2 FPS). The 4K Ultra result of 34 FPS is below the standard 60 FPS target and even below the 40 FPS threshold for many players, making it a poor choice for competitive or smooth gameplay.

Settings Recommendations

Based on the measured rows, the optimal settings depend on the target resolution and the desired frame rate. For 1080p, the Low preset at 193.1 FPS is excellent for high-refresh-rate monitors, and even Ultra at 87.3 FPS is above 60 FPS, so players can prioritize visual quality without sacrificing playability. The data suggests that 1080p High (112.6 FPS) offers a good balance between visuals and performance, as it is still well above 100 FPS.

For 1440p, the Medium preset at 96.2 FPS is a strong recommendation, as it provides a smooth experience above 90 FPS. High at 81.8 FPS is also viable, but Ultra at 59.4 FPS is borderline; it is just above 60 FPS, but any scene with heavy action could push it lower. The 1440p Low setting at 140.7 FPS is excellent for competitive play, but Medium is likely the best overall choice for most users who want a mix of quality and speed.

At 4K, the choices are more constrained. Low at 84.2 FPS is the only preset that maintains a comfortable frame rate above 60 FPS. Medium at 53.9 FPS is playable but not ideal, and High at 48.2 FPS is below the 60 FPS target. Ultra at 34 FPS is not recommended for anything but screenshot purposes. The data implies that 4K gaming with this combo requires significant settings compromises, and the best experience is achieved by either dropping to Low or reducing the resolution to 1440p.

CPU Role

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. Its 16 MB of L3 cache and 7 nm process node are modern for its generation, but the CPU’s memory support is limited to DDR4 with a dual-channel bus, providing 51.2 GB/s of bandwidth. This is a notable constraint, as Rust is a game that often requires large amounts of data to be processed and streamed, especially in multiplayer environments with many entities.

The CPU’s benchmark scores, such as cinebench_r23_multicore at 20755 and passmark_multithread at 24419, show it is a strong multi-threaded performer. However, its single-thread performance (cinebench_r23_singlecore at 2930 and 3dmark_single_thread at 899) is adequate but not exceptional by current standards. In Rust, the game’s simulation logic is often single-threaded, meaning the CPU’s single-core speed can be a bottleneck. The measured FPS at 1080p Low (193.1 FPS) suggests that the CPU can push high frame rates, but the fact that the combo ranks 592 out of 1717 indicates that other CPUs with higher single-thread scores may achieve even better results in this game.

The CPU’s PCIe Gen 3 interface (16 lanes) is another potential limitation, as the RX 7800 XT supports PCIe 4.0 x16. This means the GPU is operating at half the bandwidth of its native interface, which could slightly reduce performance in bandwidth-sensitive scenarios, though the impact is likely minimal at lower resolutions. The 65 W TDP of the 5700G is low, indicating that it runs cool and power-efficient, but it also means the CPU is not pushed to extreme clocks. The data shows that the CPU’s role is more about maintaining a baseline of performance rather than being the star of the show; the GPU’s 16 GB of VRAM and high compute throughput are what allow the combo to reach 4K Low at 84.2 FPS, while the CPU’s 16 threads help sustain those frame rates without stuttering.
