Rust

Resolution Scaling

The measured FPS data for Rust on this platform shows a predictable but revealing pattern across the three tested resolutions. At 1920x1080 with Ultra settings, the combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 3070 delivers 78.2 frames per second. Moving to 2560x1440 at the same Ultra preset drops the average to 53.8 FPS, a reduction of roughly 31%. Pushing further to 3840x2160 Ultra yields just 31.9 FPS, which represents a 41% decline from the 1440p figure and a 59% drop from the 1080p baseline.

This scaling pattern is more revealing when examining the Low settings tier. At 1920x1080 Low, the system produces 182.4 FPS, which is an exceptionally high frame rate that suggests the CPU and GPU are both operating well within their capabilities. At 2560x1440 Low, the average falls to 127.7 FPS, a 30% reduction. At 3840x2160 Low, the average drops to 75.4 FPS, another 41% decrease from the 1440p result. The consistency of these percentage drops across settings tiers indicates that resolution scaling in Rust is primarily a GPU-bound operation, with the frame rate decreasing in near-linear fashion as pixel count rises.

The gap between Low and Ultra settings widens dramatically as resolution increases. At 1080p, the difference between Low (182.4 FPS) and Ultra (78.2 FPS) is 104.2 FPS. At 1440p, that gap narrows to 73.9 FPS (127.7 vs. 53.8). At 4K, the gap shrinks further to 43.5 FPS (75.4 vs. 31.9). This compression of the settings range at higher resolutions is a classic indicator that the GPU becomes the limiting component as pixel count grows, with the RTX 3070's compute resources being consumed by raw rasterization rather than by the additional visual effects enabled by higher quality presets.

The data suggests that for smooth gameplay at 4K, users would need to select the Low preset to approach playable frame rates, while Medium at 4K (48.7 FPS) and High at 4K (44.1 FPS) both hover near the edge of what might be considered acceptable for a survival game. At 1440p, the High preset (70 FPS) provides a comfortable experience, while Ultra (53.8 FPS) remains playable but with noticeable compromise. The 1080p results show that this hardware pairing can handle even the most demanding settings with headroom, as the Ultra preset at 78.2 FPS indicates the CPU is capable of feeding the GPU adequately at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture using Samsung's 8 nm process node, with a die size of 392 mm² and 17,400 million transistors. The GPU operates with a base clock of 1500 MHz and a boost clock of 1725 MHz, paired with 8 GB of GDDR6 memory on a 256-bit bus. This configuration yields a memory bandwidth of 448.0 GB/s, which is a critical specification for Rust given the game's large, persistent world that requires constant streaming of terrain and building data.

The RTX 3070's memory subsystem appears to be a significant factor in the measured results. The 8 GB VRAM capacity is sufficient for 1080p and 1440p gameplay, as evidenced by the strong performance at those resolutions. However, at 3840x2160, the combination of higher pixel count and the game's texture streaming requirements may push against the 8 GB limit, contributing to the steep performance drop at 4K Ultra (31.9 FPS). The 448.0 GB/s bandwidth provides ample throughput for the game's asset streaming at lower resolutions, but the demands of 4K resolution with Ultra settings may exceed what this memory configuration can efficiently deliver.

The GPU's compute capabilities are substantial, with 5888 shading units, 184 texture mapping units, and 96 raster output pipelines. The FP32 performance of 20.31 TFLOPS and texture rate of 317.4 GTexel/s indicate that the RTX 3070 has significant raw processing power for the game's lighting and shadow calculations. The 46 RT cores and 184 tensor cores, while not directly utilized by Rust's standard rendering path, contribute to the GPU's overall architectural efficiency and its DirectX 12 Ultimate (12_2) feature set support.

In the context of the benchmark database, the RTX 3070 holds a percentile rank of 72 among all GPUs, with an average benchmark score of 28238. Its nearest rival, the AMD Radeon RX 6600 XT, scores 27985, placing the RTX 3070 just 0.9% ahead. The NVIDIA GeForce GTX 980 Ti scores 27956, which puts the RTX 3070 exactly 1% ahead of that older flagship. These comparisons indicate that the RTX 3070 sits in a competitive mid-to-high tier position, and the measured Rust performance aligns with this positioning.

FAQ

Q: What is the best resolution to play Rust with this hardware for a balance of visual quality and frame rate?

A: Based on the measured data, 2560x1440 with High settings provides 70 FPS, which offers a strong balance. The 1080p High preset delivers 102.9 FPS, but 1440p High retains most of the visual fidelity while maintaining a smooth frame rate. At 4K, even the Low preset only reaches 75.4 FPS, so 1440p is the practical ceiling for quality settings.

Q: How does the RTX 3070 compare to its closest rivals in synthetic benchmarks?

A: The RTX 3070 has an average benchmark score of 28238. The AMD Radeon RX 6600 XT scores 27985, which is 0.9% lower. The NVIDIA GeForce GTX 980 Ti scores 27956, which is 1% lower. The AMD FirePro S7150 scores 28409, placing it 0.6% above the RTX 3070, and the AMD Radeon R9 M295X scores 28541, which is 1.1% higher.

Q: Why does the frame rate drop so significantly when moving from Medium to Ultra at 4K?

A: At 3840x2160, the Medium preset averages 48.7 FPS, while Ultra drops to 31.9 FPS. This 35% reduction indicates that the Ultra preset's additional visual effects—likely including enhanced shadows, draw distances, and post-processing—consume a substantial portion of the RTX 3070's compute resources. The 8 GB VRAM may also become a limiting factor at 4K Ultra, as the game requires more memory for high-resolution textures.

Q: Is the Intel Core i5-13400F a bottleneck for the RTX 3070 in Rust?

A: The data suggests that at lower resolutions, the CPU keeps pace with the GPU. At 1080p Low, the system achieves 182.4 FPS, which indicates the CPU can feed frames faster than most displays can show. At 1080p Ultra, the 78.2 FPS result shows the GPU becoming the primary constraint. The CPU's 10 cores and 16 threads, with a boost clock of 4.60 GHz, provide ample processing power for Rust's simulation and physics.

Q: What is the CPU's standing relative to other processors in the database?

A: The Intel Core i5-13400F holds a percentile rank of 82 among all CPUs, with an average benchmark score of 25236. Its nearest rivals include the Intel Core i7-13620H at 25201 (0.1% lower), the AMD Ryzen 5 5600X3D at 25365 (0.5% higher), the AMD EPYC 9474F at 25103 (0.5% lower), and the AMD Ryzen AI 5 PRO 340 at 25099 (0.5% lower). This places the i5-13400F in a strong mid-range position.

Q: How does the RTX 3070's memory bandwidth affect Rust performance at different resolutions?

A: The 448.0 GB/s bandwidth is sufficient for smooth operation at 1080p and 1440p, where the frame rates remain high across all settings. At 4K, the game requires significantly more memory throughput to handle the increased pixel count, and the data shows a more pronounced performance penalty at Ultra settings (31.9 FPS) compared to Low (75.4 FPS). This suggests that memory bandwidth becomes a more significant constraint as resolution increases.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its strongest performance across all settings. The Low preset produces an average of 182.4 FPS, which is the highest frame rate recorded in this dataset. The Medium preset delivers 124.5 FPS, representing a 32% reduction from Low. The High preset yields 102.9 FPS, a further 17% decrease from Medium. The Ultra preset drops to 78.2 FPS, which is 24% lower than High and 57% lower than Low. These figures indicate that at 1080p, the RTX 3070 has substantial headroom, and users can select the High or Ultra preset while maintaining frame rates above 75 FPS.

At 2560x1440, the performance profile shifts downward. The Low preset averages 127.7 FPS, which is still a very playable frame rate. The Medium preset produces 84.1 FPS, a 34% reduction from Low. The High preset delivers 70 FPS, an 18% decrease from Medium. The Ultra preset falls to 53.8 FPS, which is 23% lower than High and 58% lower than Low. The 1440p results show that the High preset remains the recommended choice for most users, as it provides a frame rate above 60 FPS with enhanced visual quality.

At 3840x2160, the system's limitations become apparent. The Low preset averages 75.4 FPS, which is the only 4K configuration that exceeds 60 FPS. The Medium preset drops to 48.7 FPS, a 35% reduction from Low. The High preset produces 44.1 FPS, a 9% decrease from Medium. The Ultra preset falls to 31.9 FPS, which is 28% lower than High and 58% lower than Low. The 4K data reveals that the RTX 3070's 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for the most demanding settings at this resolution.

The overall ranking of this hardware combination in Rust is 775 out of 1717 tested configurations, placing it in the upper-middle portion of the database. This rank reflects the balance between the CPU's strong multi-threaded performance and the GPU's solid, but not top-tier, rasterization capabilities.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process node. It operates with a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a thermal design power of 65 W. The CPU features a cache hierarchy consisting of 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. This configuration provides strong single-threaded and multi-threaded performance, as reflected in its benchmark scores.

In synthetic benchmarks, the i5-13400F achieves a Cinebench R23 multicore score of 21279 and a single-core score of 3004. Its Geekbench results show 10971 in multicore and 2301 in single-core tests. The 3DMark results indicate scaling from 1880 in the 2-thread test to 7307 in the max-thread test, demonstrating that the processor's hybrid architecture efficiently utilizes additional threads. The Passmark multithread score of 25032 and single-thread score of 3634 place the CPU in the 82nd percentile among all processors.

Rust is known for its demanding server-side simulation and frequent physics calculations, which benefit from multi-threaded processing. The i5-13400F's 10 cores and 16 threads provide ample parallel processing capability for these tasks. The measured FPS data supports this, as the system maintains high frame rates at 1080p Low (182.4 FPS), indicating that the CPU can process game logic and feed frames to the GPU without becoming a bottleneck at lower resolutions.

The CPU's position relative to its nearest rivals shows it is well-matched with the RTX 3070. The i5-13400F's average benchmark score of 25236 is nearly identical to the Intel Core i7-13620H at 25201, with a delta of just 0.1%. This near-parity suggests that game performance is unlikely to differ meaningfully between these two processors. The 0.5% delta with the AMD Ryzen 5 5600X3D (25365) and AMD EPYC 9474F (25103) further confirms that the i5-13400F sits in a tightly contested performance bracket.

At higher resolutions, the CPU's role diminishes as the GPU becomes the primary limiting factor. The 4K Ultra result of 31.9 FPS is significantly below the 1080p Ultra figure of 78.2 FPS, and this gap is attributable to the GPU's inability to maintain frame throughput rather than any CPU deficiency. The data indicates that for Rust, the i5-13400F provides sufficient processing power to avoid CPU-bound scenarios at any resolution, allowing the RTX 3070 to operate as the performance limiter.
