CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5700 is an 8-core, 16-thread processor based on the Zen 3 architecture, built on TSMC's 7nm process. It operates with a base clock of 3.70 GHz and a boost clock of 4.60 GHz, with a 65W TDP. The processor features a 16 MB L3 cache, 512 KB L2 per core, and 64 KB L1 per core. This is a desktop-class chip that supports DDR4 memory with dual-channel configuration and a memory bandwidth of 51.2 GB/s.

Benchmark results show this CPU performs strongly in multi-threaded workloads. In Cinebench R23, it scores 20,655 points in multicore and 2,916 points in single-core. The Geekbench scores are 9,959 multicore and 1,907 single-core. The Passmark multithread score is 24,303, with a single-thread score of 3,296. In 3DMark's threaded tests, it scores 6,628 with 16 threads, 5,585 with 8 threads, and 901 with a single thread.

When placed against its nearest rivals in the CPU benchmark database, the Ryzen 7 5700 sits essentially at parity. The Intel Xeon D-2752TER scores 25,530, which is 0.1% higher. The AMD Ryzen 5 6600H scores 25,550, also 0.1% higher. The Ryzen 5 7640U scores 25,485, which is 0.1% lower. The Ryzen 7 5825U scores 25,446, which is 0.3% lower. This CPU ranks in the 78th percentile among all CPUs, with an average benchmark score of 25,517.

For a game like Rust, which is known for heavy server-side simulation and player-built structures, the multi-threaded performance of this CPU is directly relevant. The 16 threads allow the game engine to distribute tasks across cores, and the 3DMark 16-thread score of 6,628 indicates solid parallel processing capability. The single-thread performance, while lower in absolute terms compared to newer architectures, is still sufficient to handle game logic and physics calculations. The measured FPS data shows that at 1080p Low settings, the system reaches 173 FPS, which suggests the CPU is not the primary bottleneck at lower resolutions and settings. However, at 4K Ultra, the frame rate drops to 30 FPS, indicating that other components become limiting factors as resolution and visual complexity increase.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture with the Navi 32 chip, manufactured on TSMC's 5nm process. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of memory bandwidth. The GPU has a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz. The memory operates at 2438 MHz with 19.5 Gbps effective speed. The card contains 2,560 shading units, 160 texture mapping units, 96 raster operation units, and 40 ray tracing cores. It delivers 25.18 TFLOPS of FP32 performance and a pixel rate of 236.1 GPixel/s.

In GPU benchmarks, the RX 7700 scores 20,974 in Passmark G3D, 106,028 in Geekbench OpenCL, and 2,865 in 3DMark Steel Nomad DX12. Its Passmark G2D score is 1,206, and GPU compute score is 10,963. The GPU ranks in the 58th percentile among all GPUs, with an average benchmark score of 15,852. Compared to its nearest rivals, the AMD Radeon R9 370X scores 15,862 (0.1% higher), the AMD Radeon Pro W5500 scores 15,679 (1.1% lower), the Radeon RX 9060 scores 16,014 (1% higher), and the NVIDIA GeForce RTX 3060 Ti scores 16,129 (1.7% higher).

The 16 GB VRAM is substantial for Rust, which can consume significant memory due to large world maps, many entities, and high-resolution textures. The high memory bandwidth of 624.1 GB/s ensures that texture streaming and asset loading do not become bottlenecks. At 1080p High settings, the system achieves 98 FPS, and at 1440p High, it reaches 67 FPS. The drop from 1080p High to 1440p High is about 32%, which is consistent with the increased pixel count. At 4K High, the frame rate falls to 40 FPS, indicating that the GPU is under significant load at ultra-high resolutions. The GPU's performance in Rust appears to scale reasonably well with resolution, but the 4K results show that this card is more suited for 1080p and 1440p gaming in this title.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of performance degradation as resolution increases across all settings. At Low settings, the frame rate drops from 173 FPS at 1080p to 119 FPS at 1440p, a decline of 31%, and then to 70 FPS at 4K, a further decline of 41%. This scaling behavior indicates that the GPU is becoming the limiting factor at higher resolutions, even at low visual fidelity.

At Medium settings, the system delivers 116 FPS at 1080p, 80 FPS at 1440p, and 47 FPS at 4K. The percentage drops are 31% from 1080p to 1440p and 41% from 1440p to 4K, showing a similar pattern to Low settings. At High settings, the numbers are 98 FPS at 1080p, 67 FPS at 1440p, and 40 FPS at 4K, with drops of 32% and 40% respectively. Ultra settings show the most severe scaling: 75 FPS at 1080p, 51 FPS at 1440p, and 30 FPS at 4K, representing drops of 32% and 41%.

The consistency of these percentage drops across all settings is notable. This suggests that the scaling is primarily driven by the GPU's rendering workload, which increases with pixel count. The fact that even at Low settings the 4K frame rate (70 FPS) is significantly lower than the 1080p Low frame rate (173 FPS) indicates that the GPU is the bottleneck at 4K, regardless of visual complexity. The CPU's role appears to be relatively consistent across resolutions, as the frame rate differences between settings at the same resolution are substantial, but the resolution-based scaling is uniform.

At 1080p, the system achieves high frame rates even at Ultra settings (75 FPS), which suggests the CPU is capable of feeding the GPU at this resolution. The 173 FPS at 1080p Low indicates that the CPU has headroom, as the GPU is not fully utilized at this lower resolution and setting combination. As resolution increases, the GPU becomes more heavily loaded, and the frame rate drops accordingly. This analysis points to the RX 7700 as the primary limiting component at 1440p and 4K, while the Ryzen 7 5700 provides sufficient processing power at 1080p.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset offers the most balanced experience across all resolutions. At 1080p Medium, the system achieves 116 FPS average with a minimum of 99 FPS and maximum of 133 FPS. This provides a smooth experience well above the 60 FPS threshold, with enough headroom for demanding scenes. The minimum FPS of 99 ensures that even in heavy combat or resource-intensive areas, the frame rate remains playable.

At 1440p Medium, the average FPS is 80, with a minimum of 68 and maximum of 92. This is still comfortably above 60 FPS, and the minimum of 68 suggests that frame pacing remains consistent even during intense gameplay moments. The visual improvement from Low to Medium is significant in Rust, as textures and draw distances are noticeably better, while the performance cost is manageable.

At 4K Medium, the average FPS drops to 47, with a minimum of 40 and maximum of 54. This is borderline playable, but the minimum of 40 FPS may result in noticeable stuttering during fast-paced action. For 4K gaming, the Low preset at 70 FPS average is a better choice, as it maintains a more consistent experience. The High preset at 4K delivers only 40 FPS, which is below the playable threshold for most users.

For players prioritizing frame rate over visual fidelity, the Low preset at 1080p offers 173 FPS, which is ideal for competitive play. However, the Medium preset at 1080p provides a better balance, with 116 FPS and significantly improved visuals. The Ultra preset, while offering the best image quality, drops to 75 FPS at 1080p, 51 FPS at 1440p, and 30 FPS at 4K, making it suitable only for players with 1080p displays who prioritize visuals over performance.

The data suggests that Medium is the recommended preset for most users, as it provides the best combination of visual quality and performance across all tested resolutions. For 4K users, Low is the only viable option for smooth gameplay, while 1440p users can comfortably use Medium or High depending on their preference for visual fidelity.
