Resolution Scaling

The measured FPS data for Rust with the AMD Ryzen 7 5700G and AMD Radeon RX 9070 reveals a clear pattern of scaling across resolutions. At 1920x1080 with High settings, the combo produces 121.7 FPS, which drops to 80.9 FPS at 2560x1440, and further to 47.1 FPS at 3840x2160. This represents a 33.5% reduction from 1080p to 1440p, and a 61.3% reduction from 1080p to 4K at the same settings.

The scaling behavior shifts when examining Low settings. At 1920x1080 Low, the system achieves 190.3 FPS, which drops to 144.9 FPS at 1440p and 85.5 FPS at 4K. The percentage drops are 23.9% and 55.1% respectively. The smaller relative decline at lower settings suggests that the GPU becomes more of a limiting factor at higher quality presets, while at Low settings, the CPU has more headroom to push frame rates.

Ultra settings show the steepest curve: 92.3 FPS at 1080p, 62.1 FPS at 1440p, and 35.3 FPS at 4K. This is a 32.7% drop from 1080p to 1440p and a 61.8% drop to 4K. The consistency of these percentage drops across High and Ultra settings indicates that the GPU workload scales predictably with pixel count, while the CPU contribution becomes relatively more significant at lower resolutions.

The data points to the GPU being the primary constraint at 4K, particularly at Ultra where the RX 9070's 16 GB of GDDR6 memory and 644.6 GB/s bandwidth are pushed hard. At 1080p, the frame rates exceed 120 FPS on High and approach 190 FPS on Low, suggesting that the Ryzen 7 5700G's 8 cores and 16 threads are sufficient to keep the GPU well-fed at lower resolutions. The 51.2 GB/s memory bandwidth of the CPU platform does not appear to bottleneck the GPU at 1080p, but the gap between 1080p and 1440p results grows as settings increase.

GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with a 4 nm process from TSMC. Its 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is substantial for a game like Rust that features large open-world environments with many dynamic objects. The GPU has 3584 shading units, 224 texture mapping units, and 128 render output units, with 56 ray tracing cores.

Clock speeds matter in Rust's varied scenes. The base clock is 1330 MHz, with a game clock of 2070 MHz and a boost clock of 2520 MHz. The measured FPS data shows that the GPU's performance scales predictably with resolution. At 4K Ultra, the 35.3 FPS result suggests the GPU is heavily loaded, while at 1080p Low, the 190.3 FPS figure indicates the GPU has significant headroom. The 36.13 TFLOPS FP32 compute throughput is adequate for the game's shader complexity, but the 4K results show that Ultra settings exceed what this GPU can deliver at playable frame rates.

The GPU's 220 W TDP and dual-slot cooler design suggest it is a mainstream-to-high-end part. The 2x 8-pin power connectors and 550 W suggested PSU indicate the power delivery requirements are modest relative to flagship cards. The PCIe 5.0 x16 bus interface ensures no bandwidth limitation from the motherboard connection. The Radeon RX 9070's percentile ranking of 79 among all GPUs places it solidly in the upper tier, though not at the very top.

The memory configuration is particularly relevant for Rust. The 16 GB VRAM capacity is more than sufficient for the game's texture streaming and asset loading at 4K. The 256-bit bus width and 644.6 GB/s bandwidth allow for rapid data transfer between VRAM and the GPU cores, which helps maintain consistent frame times in scenes with many players and structures. The GDDR6 memory at 20.1 Gbps effective speed represents a balanced configuration for this architecture.

Measured FPS Breakdown

At 1920x1080, the combo shows a clear progression across settings. Low averages 190.3 FPS, Medium averages 145.8 FPS, High averages 121.7 FPS, and Ultra averages 92.3 FPS. The gap between Low and Medium is 44.5 FPS, while the gap between Medium and High is 24.1 FPS, and High to Ultra is 29.4 FPS. This suggests that the transition from Medium to High is the least demanding, while Low to Medium and High to Ultra have similar performance costs.

At 2560x1440, the results are 144.9 FPS on Low, 100.7 FPS on Medium, 80.9 FPS on High, and 62.1 FPS on Ultra. The relative gaps are 44.2 FPS between Low and Medium, 19.8 FPS between Medium and High, and 18.8 FPS between High and Ultra. The diminishing returns from High to Ultra are less pronounced at 1440p than at 1080p, indicating that the GPU is becoming more of a limiting factor.

At 3840x2160, the frame rates are 85.5 FPS on Low, 57.4 FPS on Medium, 47.1 FPS on High, and 35.3 FPS on Ultra. The gap between Low and Medium is 28.1 FPS, Medium to High is 10.3 FPS, and High to Ultra is 11.8 FPS. The compression of these gaps at 4K confirms that the GPU is the primary constraint at this resolution, as the incremental cost of higher settings becomes relatively smaller.

The data shows that 1080p is the sweet spot for high refresh rate monitors, with Low settings providing nearly 200 FPS and High settings still exceeding 120 FPS. At 1440p, the system can maintain above 60 FPS on all settings except Ultra, which sits barely above 60 FPS at 62.1 FPS. At 4K, only Low settings exceed 60 FPS, with Medium at 57.4 FPS slightly below that threshold.

CPU Role

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture with the Cezanne codename. It operates at a 3.80 GHz base clock and 4.60 GHz boost clock, with a 65 W TDP. The CPU is built on TSMC's 7 nm process and features 16 MB of L3 cache, with 512 KB of L2 cache per core and 64 KB of L1 cache per core. It supports DDR4 memory in dual-channel configuration with 51.2 GB/s bandwidth.

Rust is known to be CPU-intensive due to its large persistent world and many simultaneous player interactions. The 8 cores and 16 threads of the 5700G provide ample parallel processing capability. The multi-threaded benchmark results show strong performance: 2092 in Cinebench R15 multicore, 8717 in R20 multicore, and 20755 in R23 multicore. These scores suggest the CPU can handle the game's physics and simulation workloads without becoming a bottleneck.

The single-thread performance is also important for Rust's main game loop and rendering thread. The 3DMark single-thread score of 899 and Cinebench R23 single-core score of 2930 indicate solid single-thread capability. The boost clock of 4.60 GHz is competitive for gaming workloads that rely on one or two cores. The 51.2 GB/s memory bandwidth is adequate for the CPU's needs, though the GPU's 644.6 GB/s bandwidth is far higher, which is expected given the different memory architectures.

The CPU's integrated Radeon Vega 8 graphics are not used for this benchmark, as the discrete RX 9070 handles all rendering. However, the presence of integrated graphics means the 5700G can serve in systems without a discrete GPU, though performance would be far lower. The 5700G's 16 MB L3 cache is moderate by modern standards, but sufficient for Rust's working set. The CPU's 7 nm process and 65 W TDP make it power-efficient, which is beneficial in smaller form factor systems.

The benchmark results for the CPU show it performs well in both multi-threaded and single-threaded workloads. The Passmark multithread score of 24419 and single-thread score of 3283 place it in a strong position for gaming. The 3DMark 8-thread score of 5648 and max-thread score of 6627 indicate good scaling with additional threads. For Rust specifically, the combination of 8 cores and strong single-thread performance helps maintain high frame rates at 1080p and 1440p, as evidenced by the measured FPS results.
