Rust

Rust is a demanding survival title that stresses both CPU and GPU, and the measured frame rates for the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4070 combination reveal a configuration that scales predictably across resolutions. At 1080p with Low settings, the combo delivers an average of 200.3 FPS, which drops to 152.2 FPS at Medium and 127.9 FPS at High. The Ultra preset at 1080p yields 96.9 FPS. Moving to 1440p, the average frames per second are 157.9 on Low, 103.7 on Medium, 86.2 on High, and 70.0 on Ultra. At 4K, the performance curve tightens considerably: 88.8 FPS on Low, 63.2 FPS on Medium, 53.6 FPS on High, and 41.2 FPS on Ultra. The transition from 1080p Low to 4K Low represents a 55.7% reduction in frame rate, while the same resolution jump at Ultra settings shows a 57.5% drop, indicating that the GPU becomes the primary bottleneck as pixel count rises.

Resolution Scaling

The data shows a clear pattern where the RTX 4070’s rendering load increases sharply with resolution, but the CPU keeps pace until the highest pixel counts. At 1080p, the gap between Low and Ultra is 103.4 FPS, suggesting that the Ryzen 9 5900X has ample headroom to feed the GPU even at high frame rates. The 5900X’s 12 cores and 24 threads, with a boost clock of 4.80 GHz, provide enough single-thread throughput for Rust’s simulation logic, which is why 1080p Low exceeds 200 FPS. However, at 4K Ultra, the average drops to 41.2 FPS, a figure that highlights the GPU’s limits rather than the CPU’s. The difference between 1440p Ultra (70.0 FPS) and 4K Ultra (41.2 FPS) is a 41.1% reduction, which is a steeper decline than the 24.2% drop from 1080p Ultra to 1440p Ultra. This nonlinear scaling indicates that the RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are sufficient for 1440p but become strained at 4K, particularly with Ultra settings that increase texture and shader complexity.

Interestingly, the low preset at 4K still achieves 88.8 FPS, which suggests that reducing graphical fidelity can offset the resolution penalty. The medium preset at 4K (63.2 FPS) and high preset at 1440p (86.2 FPS) show that the combo is most efficient when the GPU is not overburdened. For players targeting 4K, the data implies that High settings are borderline playable at 53.6 FPS, but dropping to Medium provides a more comfortable margin. The scaling from Low to Ultra at each resolution is consistent: 1080p shows a 51.6% performance loss, 1440p shows a 55.7% loss, and 4K shows a 53.6% loss. This consistency suggests that the RTX 4070’s clock behavior—base 1920 MHz, boost 2475 MHz—responds predictably to increased load, but the 192-bit memory bus becomes a limiting factor at higher resolutions.

How This Combo Ranks

In the benchmark database, this CPU-GPU pairing holds the 415th position out of 1717 tested combinations for Rust, placing it in the top 24.2% of all configurations. This rank reflects a balanced setup that outperforms the majority of systems but does not reach the top tier reserved for flagship hardware. The CPU itself sits in the 90th percentile against all CPUs, with an average benchmark score of 39453, while the GPU ranks in the 81st percentile with an average score of 37283. The combo’s mid-tier rank is consistent with the measured frame rates, which are strong at 1080p but fall short of elite levels at 4K. For context, the Ryzen 9 5900X’s nearest rival, the AMD EPYC 4245P, has an average score of 39383, a mere 0.2% difference, indicating that the 5900X delivers performance nearly identical to that server-class chip in synthetic tests. The Intel Core i7-13700F trails by 0.9% with a score of 39095, while the AMD Ryzen 7 PRO 8845HS leads by 0.7% and the Intel Core i7-13700 leads by 1.0%.

These small deltas in CPU benchmarks suggest that the 5900X is not the limiting factor in Rust; rather, the RTX 4070’s 81st percentile ranking among GPUs is more indicative of the combo’s overall position. The GPU’s nearest rival, the AMD Radeon RX Vega 56, scores 37507, which is 0.6% higher, and the NVIDIA GeForce MX570 A is 1.9% ahead, though those are likely outlier results. The combo rank of 415 out of 1717 implies that many systems with newer or higher-end GPUs surpass this pairing, but the 5900X’s strong multi-threaded performance ensures that CPU-bound scenarios, such as Rust’s server-side calculations, remain fluid. The data indicates that this combo is a solid mid-range choice, delivering 127.9 FPS at 1080p High and 86.2 FPS at 1440p High, which are respectable figures for competitive play.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process from TSMC, packing 35,800 million transistors into a 294 mm² die. Its 5888 shading units, 184 texture mapping units, and 64 raster output processors are supported by 46 ray tracing cores and 184 tensor cores, making it a capable GPU for modern titles. The memory subsystem consists of 12 GB of GDDR6X on a 192-bit bus, providing 504.2 GB/s of bandwidth. The base clock is 1920 MHz, with a boost clock of 2475 MHz, and the memory runs at 1313 MHz, which translates to 21 Gbps effective. These specifications allow the GPU to achieve a pixel rate of 158.4 GPixel/s and a texture rate of 455.4 GTexel/s, with FP32 performance at 29.15 TFLOPS.

In Rust, the GPU’s role is most evident at higher resolutions and settings. At 4K Ultra, the average FPS of 41.2 is below the 60 FPS threshold, which aligns with the GPU’s 81st percentile ranking. The 12 GB VRAM is adequate for the game’s textures, but the 192-bit memory bus limits bandwidth at 4K, where the engine’s draw calls and shadow maps demand more data throughput. The RTX 4070’s boost clock of 2475 MHz helps maintain performance at 1440p, where the combo achieves 86.2 FPS on High, but the GPU’s thermal and power envelope (200 W TDP) means it cannot sustain high clocks under extreme loads. The transition from 1080p to 4K shows a 70.8% reduction in FPS at Ultra settings, which is a steeper drop than the 55.7% reduction at Low, indicating that the GPU’s compute units are saturated by the higher preset’s effects, such as ambient occlusion and volumetric lighting. The RTX 4070’s DirectX 12 Ultimate support and Vulkan 1.4 compatibility ensure it can handle Rust’s rendering pipeline, but the data suggests that 1440p is the sweet spot for this GPU.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, codenamed Vermeer, fabricated on TSMC’s 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a 64 MB L3 cache and 512 KB of L2 cache per core. The processor supports DDR4 memory in a dual-channel configuration, offering 51.2 GB/s of memory bandwidth, and it connects via PCIe Gen 4. Its 105 W TDP is modest for a 12-core part, and it occupies the AMD Socket AM4 platform. In synthetic benchmarks, the 5900X achieves a Cinebench R23 multi-core score of 33150 and a single-core score of 4680, while its Geekbench multi-core score is 11877 and single-core is 2202. The 3DMark results show a maximum thread score of 10075, with 16-thread and 8-thread scores of 9075 and 6601, respectively.

In Rust, the CPU’s role is critical for handling the game’s server-side simulation, which includes entity updates, physics, and network synchronization. The 5900X’s high single-thread performance, evidenced by the 3DMark single-thread score of 941, ensures that the game’s main thread does not bottleneck the GPU. At 1080p Low, the combo reaches 200.3 FPS, which is a clear indication that the CPU can process frames faster than the GPU can render them. The 24 threads also help with background tasks, such as asset streaming and audio, which is why the frame rate only drops by 51.6% when moving from Low to Ultra at 1080p. The CPU’s 90th percentile ranking against all CPUs, with an average benchmark score of 39453, places it ahead of most desktop processors, but its nearest rivals show that the performance gap is narrow. The AMD EPYC 4245P is just 0.2% slower, and the Intel Core i7-13700 is 1.0% faster, meaning that the 5900X is competitive but not dominant in 2024. The CPU’s 7 nm process and dual-chiplet design (2x 74 mm² die size) contribute to its efficiency, but the 64 MB L3 cache is the key asset for Rust’s frequently accessed data, reducing memory latency and improving frame pacing. Overall, the 5900X provides a strong foundation for this combo, ensuring that the GPU is the limiting factor at higher resolutions, which is the expected behavior for a balanced system.
