Rust

Rust presents a demanding workload that scales heavily with both resolution and quality settings. The measured data for the Intel Core i5-13400F paired with the Intel Arc B570 shows a configuration that is firmly positioned for 1080p gaming, with playable results at 1440p only when settings are lowered. The frame rates across the board indicate that this combination is GPU-limited in most scenarios, but the CPU's capabilities ensure that it is not the primary bottleneck, even at lower resolutions.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all quality presets, clearly identifying the GPU as the limiting component in this pairing. At Low settings, the average frame rate falls from 118 FPS at 1920x1080 to 81 FPS at 2560x1440, a reduction of 37 FPS. Moving to 4K at Low settings, the average further drops to 48 FPS, which is less than half of the 1080p result. This scaling pattern is typical of a GPU that is being pushed to its limits, as the rendering resolution increases the pixel count that the Arc B570 must process, directly impacting its fillrate and bandwidth capabilities.

The trend is similar at Medium settings, where the average frame rate goes from 79 FPS at 1080p to 54 FPS at 1440p, and then down to 32 FPS at 4K. The gap between 1080p and 4K at Medium settings is 47 FPS, a substantial loss that makes 4K unplayable for smooth gameplay. At High settings, the averages are 67 FPS at 1080p, 46 FPS at 1440p, and 27 FPS at 4K. The scaling here shows that even at 1440p, the High preset is borderline, and 4K is not a viable option for a consistent experience.

Ultra settings are the most demanding, with the average frame rate at 1080p being 51 FPS, dropping to 35 FPS at 1440p and a very low 21 FPS at 4K. The data reveals that the Arc B570's 10 GB of VRAM and 160-bit memory bus are sufficient for 1080p, but the 4K results suggest that the GPU's compute throughput and memory bandwidth are overwhelmed. The scaling from 1440p to 4K is particularly punishing, with an average loss of over 40% of the frame rate across all presets, confirming that this combo is not designed for high-resolution gaming.

How This Combo Ranks

Within the database of tested combinations for Rust, this specific pairing of the Intel Core i5-13400F and Intel Arc B570 ranks at 2349 out of 2953 combos. This places it in the bottom 21% of tested configurations, indicating that while it is functional, it is not a high-performance setup for this particular game. The rank reflects the measured FPS data, which shows that the combo struggles to maintain high frame rates at higher resolutions and settings.

The performance is heavily influenced by the GPU's position in the market. The Arc B570's average benchmark score of 20556 places it in the 65th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile, which has an average score of 20534, and the Intel Arc A750, which scores 20582. The delta percentages are minimal, with the B570 being 0.1% ahead of the RTX 3070 Mobile and 0.1% behind the Arc A750. This suggests that the B570's raw compute performance is comparable to these other cards, but in Rust specifically, the combo's rank is dragged down by the overall system balance.

The CPU, on the other hand, is a strong performer in its own right. The i5-13400F has an average benchmark score of 25292, placing it in the 77th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 9 6900HS and the AMD Ryzen 5 5600X3D, with scores of 25284 and 25365 respectively, showing that the i5 is competitive with these chips. However, the combination's low rank in Rust suggests that the GPU cannot fully utilize the CPU's potential, especially at higher resolutions where the graphics card becomes the primary bottleneck.

GPU Role

The Intel Arc B570 is the core component driving the visual output for this combo, and its specifications directly correlate with the measured performance in Rust. The GPU is built on the Xe2-HPG architecture with a 5 nm process node from TSMC, featuring 19,600 million transistors on a 272 mm² die. It operates at a fixed clock speed of 2500 MHz for both base and boost, which is a relatively high frequency that helps maintain consistent performance across different workloads.

The memory subsystem consists of 10 GB of GDDR6 on a 160-bit bus, providing a bandwidth of 380.0 GB/s. In Rust, which is known for its large, open-world environments and complex textures, this bandwidth is sufficient for 1080p gameplay but becomes a limiting factor at 4K. The high-resolution data shows a significant drop in frame rates, which is likely due to the memory bus width and bandwidth being insufficient to feed the GPU's 2304 shading units and 80 ROPs at higher pixel counts.

The GPU's texture rate of 360.0 GTexel/s and pixel rate of 200.0 GPixel/s are respectable for its class. The FP32 performance of 11.52 TFLOPS indicates a mid-range compute capability. In the measured results, the GPU shows a clear progression of performance degradation as settings increase from Low to Ultra. At 1080p, the difference between Low (118 FPS) and Ultra (51 FPS) is 67 FPS, showing a 56% performance loss when maxing out the settings. This is a typical response from a GPU that is being stressed by increased shading complexity, shadow quality, and draw distances, all of which are demanding in Rust.

Measured FPS Breakdown

The measured frame rate data provides a comprehensive look at how this combo handles Rust across three resolutions and four quality presets. At 1920x1080, the results are mostly playable, with the Low preset achieving an average of 118 FPS, which is excellent for competitive or smooth gameplay. The Medium preset drops to an average of 79 FPS, with a minimum of 67 FPS and a maximum of 91 FPS, indicating a stable experience. High settings yield 67 FPS on average, which is still smooth, but Ultra settings bring the average down to 51 FPS, showing a noticeable dip in fluidity.

At 2560x1440, the performance becomes more constrained. The Low preset manages an average of 81 FPS, which is good, but the Medium preset falls to 54 FPS with a minimum of 46 FPS and a maximum of 62 FPS, creating a less consistent experience. High settings at 1440p produce an average of 46 FPS, which is on the edge of playability for some users, while Ultra drops to 35 FPS, which is likely too choppy for a smooth experience.

The 3840x2160 results are the most demanding and show the combo's limitations clearly. Low settings average 48 FPS, which is technically playable but not ideal. Medium settings average 32 FPS with a minimum of 27 FPS and a maximum of 37 FPS, indicating significant frame pacing issues. High settings average 27 FPS, and Ultra averages just 21 FPS, both of which are below the threshold for a comfortable gaming experience. These numbers confirm that 4K gaming is not a viable option for this hardware configuration in Rust.

Settings Recommendations

Based on the measured data, the optimal experience for this combo is achieved at 1920x1080 with the Medium or High preset. The Medium preset offers an average of 79 FPS with a minimum of 67 FPS, providing a good balance between visual quality and smoothness. This is the recommended setting for most users, as it ensures that the frame rate does not dip below 60 FPS, which is important for a game like Rust where quick reactions can be critical.

For users with higher refresh rate monitors or those who prioritize performance, the Low preset at 1080p delivers an outstanding average of 118 FPS, which is ideal for competitive play. However, the visual fidelity will be noticeably reduced, which may impact the ability to spot distant enemies or environmental details. The High preset at 1080p is also viable, with an average of 67 FPS, but it does not offer the same headroom as Medium, and frame drops may occur in busy scenes.

At 2560x1440, the only recommended setting is Low, which averages 81 FPS. This provides a smooth experience, but the Medium preset's 54 FPS average and 46 FPS minimum might be acceptable for some users who prefer better visuals over absolute smoothness. The High and Ultra presets at 1440p should be avoided, as they produce averages below 50 FPS, which can lead to a less responsive feel. For 4K, the data suggests that no setting provides a satisfactory experience, with even Low averaging only 48 FPS, making it unsuitable for serious gameplay.

CPU Role

The Intel Core i5-13400F is a Raptor Lake-S architecture processor with 10 cores and 16 threads, operating at a base clock of 2.50 GHz and a boost clock of 4.60 GHz. This CPU is a strong performer, as evidenced by its benchmarks, including a Cinebench R23 multi-core score of 22604 and a single-core score of 3191. These scores indicate that the CPU can handle the complex simulation and AI tasks that Rust requires, which are often single-threaded and sensitive to clock speed.

In the context of this game, the CPU's role is to manage the game's world, including physics, entity interactions, and server-side calculations. The 10 cores and 16 threads are more than sufficient for Rust, which typically scales well up to 8 threads. The L3 cache of 20 MB shared across the cores helps reduce latency when accessing frequently used data, which is beneficial for maintaining stable frame times.

The measured FPS data shows that the CPU is not the primary bottleneck, as the frame rates scale predictably with resolution and settings, which are GPU-dependent. At 1080p Low, the CPU is able to feed the GPU enough data to achieve 118 FPS, indicating that its single-thread performance is adequate for high frame rates. The boost clock of 4.60 GHz is particularly important for Rust, as it relies heavily on single-core performance for world updates. The CPU's 65W TDP and dual-channel memory support for DDR4 and DDR5 ensure that it can deliver consistent performance without thermal throttling in a standard desktop setup.
