Rust

The Intel Core i5-13400F paired with the AMD Radeon RX 580 produces a specific performance profile in Rust, characterized by a significant gap between low and ultra settings. At 1080p, the combination delivers playable frame rates on Low settings but struggles to maintain smoothness at higher quality presets. The data indicates this combo ranks in the lower percentile of tested systems, primarily limited by the GPU's age and the game's demanding nature.

FAQ

Q: What is the best resolution and setting combination for this hardware in Rust?

A: The most playable result is at 1920x1080 with Low settings, yielding an average of 76.1 FPS. Medium settings at the same resolution drop to 49.7 FPS, while High produces 39.4 FPS and Ultra only 31.2 FPS.

Q: How does the CPU's core configuration influence performance in Rust?

A: The Intel Core i5-13400F features 10 cores and 16 threads with a boost clock of 4.60 GHz. Its multi-threaded capabilities are reflected in a Cinebench R23 multicore score of 21279, which helps maintain frame pacing in Rust's simulation-heavy world, though the GPU often becomes the limiting factor.

Q: Is the RX 580's 8 GB VRAM sufficient for Rust at high resolutions?

A: At 3840x2160, the GPU's 8 GB of GDDR5 memory with 256.0 GB/s bandwidth is insufficient for smooth gameplay; even Low settings only reach 29.4 FPS. At 2560x1440, Low settings achieve 49.4 FPS, but High settings fall to 26.3 FPS.

Q: How does this combo's overall rank compare to other tested systems?

A: The combo ranks 1596 out of 1717 tested combinations in Rust, placing it in the bottom 7% of systems. This low ranking is consistent with the measured FPS, which shows the hardware is not well-suited for high-fidelity Rust gameplay.

Q: What is the performance difference between Low and Ultra settings at 1080p?

A: At 1920x1080, the gap between Low (76.1 FPS) and Ultra (31.2 FPS) is 44.9 FPS, representing a 144% increase in frame rate when dropping from Ultra to Low. This demonstrates the GPU's sensitivity to pixel shading and texture quality.

Q: Does the CPU bottleneck the GPU in this configuration?

A: Benchmark data suggests the CPU is not the primary constraint. The i5-13400F's PassMark multithread score of 25032 and single-thread score of 3634 indicate strong processing power, yet the GPU's PassMark G3D score of 8813 shows it lags behind, making the GPU the performance limiter in most scenarios.

How This Combo Ranks

The combination of the Intel Core i5-13400F and AMD Radeon RX 580 achieves a rank of 1596 out of 1717 tested combos in Rust, placing it firmly in the lower quartile of systems. This ranking is not surprising given the measured FPS data, which shows the system only crosses the 60 FPS threshold at 1080p Low settings. The CPU itself is strong, with a percentile of 82 against all CPUs, but the GPU's percentile of 53 against all GPUs drags the overall system down.

In practical terms, this combo ranks below the vast majority of systems tested, meaning players will need to make significant compromises in visual quality to achieve playable frame rates. The rank suggests that while the CPU is capable of feeding frames, the GPU cannot keep up with the demands of Rust's rendering pipeline at higher settings. The data indicates this is a balanced pairing in terms of bottleneck, but the balance is at a low performance level, making it suitable for older or less demanding titles rather than modern survival games at high fidelity.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, operating on the Intel Socket 1700 platform. Its base clock of 2.50 GHz can boost up to 4.60 GHz, providing substantial single-thread performance that is critical for Rust's physics and entity updates. The CPU's 20 MB of shared L3 cache helps maintain data locality, which benefits the game's streaming of world data.

In synthetic benchmarks, the i5-13400F demonstrates robust multi-threading with a Cinebench R23 multicore score of 21279 and a Geekbench multicore score of 10971. Single-thread performance is equally solid, with a Cinebench R23 single-core score of 3004 and a PassMark single-thread score of 3634. These scores place the CPU in the 82nd percentile of all CPUs, indicating it can handle Rust's CPU-intensive tasks without becoming a bottleneck.

However, the measured FPS data shows that the CPU's potential is not fully utilized. At 1080p Low, where GPU load is minimized, the system achieves 76.1 FPS, suggesting the CPU can drive higher frame rates if the GPU were faster. The CPU's performance is further evidenced by its 3DMark 16-thread score of 7314, which aligns with its multi-core capabilities. In this pairing, the CPU is performing its role effectively; it is the GPU that limits overall system performance.

Measured FPS Breakdown

At 1920x1080, the resolution most common for this class of hardware, the measured FPS shows a clear hierarchy. Low settings produce an average of 76.1 FPS, which is comfortably playable. Medium settings drop to 49.7 FPS, a 35% reduction from Low. High settings yield 39.4 FPS, and Ultra settings fall to 31.2 FPS, which is below the threshold for smooth gameplay in a fast-paced survival game.

Moving to 2560x1440, the performance takes a significant hit. Low settings average 49.4 FPS, which is still usable but noticeably less smooth than 1080p. Medium settings drop to 32.4 FPS, while High settings result in 26.3 FPS. Ultra settings at this resolution are nearly unplayable at 24.4 FPS, highlighting the GPU's limitations at higher pixel counts.

At 3840x2160, the RX 580 is clearly out of its depth. Low settings manage only 29.4 FPS, Medium drops to 22.6 FPS, High falls to 14.6 FPS, and Ultra bottoms out at 15.2 FPS. These numbers indicate that 4K gaming is not feasible with this combination, even at the lowest quality presets. The scaling across resolutions shows that the GPU is the primary limiting factor, as the CPU maintains consistent performance capabilities.

GPU Role

The AMD Radeon RX 580 is based on the Polaris 20 chip, manufactured on a 14 nm process at GlobalFoundries. It features 2304 shading units, 144 texture mapping units, and 32 ROPs, with a boost clock of 1340 MHz. The GPU is equipped with 8 GB of GDDR5 memory on a 256-bit bus, providing 256.0 GB/s of bandwidth. Its compute capabilities include 6.175 TFLOPS of FP32 performance.

In benchmark tests, the RX 580 achieves a PassMark G3D score of 8813 and a Geekbench OpenCL score of 37453, placing it in the 53rd percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 950, which scores 13549, and the GTX 570 at 13564, indicating the RX 580 is roughly equivalent to those older cards. The GPU's DirectX 12 performance is weak, with a 3DMark Steel Nomad score of 1005, which aligns with its poor performance in modern games.

The measured FPS data confirms that the GPU is the bottleneck in this configuration. At 1080p Low, the system achieves 76.1 FPS, but the frame rate drops dramatically as settings increase, indicating the GPU's shading units and memory bandwidth are overwhelmed by higher quality textures and effects. The 8 GB VRAM is sufficient for 1080p, but at 4K, the memory bandwidth of 256.0 GB/s is insufficient, leading to sub-30 FPS performance at all settings. The GPU's end-of-life production status and 185 W TDP further underscore its age, making it a poor match for modern titles like Rust at high settings.
