Rust

The Intel Core i5-12400 paired with the Intel Arc B570 delivers a playable but constrained experience in Rust, with performance heavily dictated by resolution and preset. The measured data shows a system that is clearly capable at 1080p but struggles to maintain fluid frame rates as pixel count increases, revealing a bottleneck that shifts depending on the workload.

Resolution Scaling

The frame rate drop from 1920x1080 to 3840x2160 is steep and consistent across all settings, indicating that the rendering pipeline becomes progressively more taxing on the GPU as resolution increases. At High settings, the average FPS falls from 67 at 1080p to 46 at 1440p, a reduction of 21 frames, and then to 27 at 4K, which is a 40-frame drop from the 1080p baseline. This pattern is characteristic of a GPU-limited scenario at higher resolutions, where the Arc B570's 10 GB of GDDR6 memory and 160-bit bus width are pushed to their limits.

The scaling from Medium settings tells a similar story. The average FPS at 1080p is 79, dropping to 54 at 1440p and then to 32 at 4K. The percentage decline from 1080p to 4K is approximately 59%, which is a significant penalty. For Low settings, the trend is even more pronounced: 118 FPS at 1080p falls to 81 at 1440p and then to 48 at 4K. The 4K Low result is only 41% of the 1080p Low result, showing that even at the lowest graphical fidelity, the resolution overhead is substantial.

This data suggests that at 1080p, the system is likely balanced, with the CPU able to feed the GPU adequately. However, at 1440p and especially 4K, the GPU becomes the limiting component. The jump from Ultra at 1440p (35 FPS) to Ultra at 4K (21 FPS) is a 40% reduction, which confirms that the Arc B570's compute resources, rated at 11.52 TFLOPS FP32, are insufficient for high-fidelity 4K rendering in Rust.

The min FPS values recorded for Medium settings provide additional insight into frame pacing. At 1080p Medium, the minimum is 67 FPS, which matches the average of 1080p High. At 1440p Medium, the min is 46 FPS, and at 4K Medium, it is 27 FPS. These minimums are not far from the averages, suggesting relatively stable frame delivery rather than severe spikes. The spread between min and max at each resolution is narrow, with 1080p Medium ranging from 67 to 91 FPS, indicating that the system does not suffer from extreme stuttering, but rather a consistent level of performance that degrades with resolution.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo depends heavily on the target resolution and desired frame rate. For 1920x1080, Low settings provide the highest average FPS at 118, which is well above the threshold for smooth gameplay. Medium settings at 1080p yield 79 FPS, which is still very playable and offers a better balance of visual quality and performance. High settings at 1080p drop to 67 FPS, which is acceptable but begins to approach the lower boundary for competitive play. Ultra at 1080p is the least favorable, with an average of 51 FPS, which may feel sluggish in fast-paced scenarios.

At 2560x1440, the choices become more constrained. Low settings deliver 81 FPS, which is excellent for this resolution. Medium settings provide 54 FPS, which is playable but may require some adjustment to expectations. High settings at 46 FPS are on the edge of playability, and Ultra at 35 FPS is likely too demanding for a consistent experience.

For 3840x2160, the data shows that only Low settings approach a playable frame rate, with an average of 48 FPS. Medium at 32 FPS is marginal, and High at 27 FPS or Ultra at 21 FPS are not recommended for any serious gameplay. The best experience per the measured rows is clearly at 1080p with Low or Medium settings, where the system can maintain high frame rates without compromising the visual presentation too severely. The 1440p Low setting also offers a strong alternative for users with higher-resolution monitors who prioritize frame rate over visual fidelity.

GPU Role

The Intel Arc B570 is the primary driver of the performance differences seen across resolutions. Its specifications include 2304 shading units, 144 texture mapping units, and 80 render output units. The GPU operates at a fixed clock speed of 2500 MHz for both base and boost, which is notable for consistent performance. The memory subsystem consists of 10 GB of GDDR6 on a 160-bit bus, providing a bandwidth of 380.0 GB/s. This bandwidth is a critical factor, as Rust's open-world environments with many assets can be memory-bandwidth intensive.

The GPU's benchmark scores place it in the 65th percentile among all GPUs. Its average benchmark score is 20556, which is nearly identical to its nearest rivals. The data shows it is 0.1% ahead of the NVIDIA GeForce RTX 3070 Mobile and 0.1% behind the Intel Arc A750, with both deltas being negligible in real-world terms. This indicates that the Arc B570 performs at a level comparable to these mid-range options, which aligns with the measured FPS results in Rust.

The VRAM capacity of 10 GB appears sufficient for the tested scenarios, as there is no indication of texture thrashing or memory overflow in the data. The pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s are moderate figures that explain the GPU's inability to maintain high FPS at 4K. The GPU's transistor count of 19,600 million on a 5 nm process from TSMC suggests a modern design, but the raw throughput is not enough to overcome the demands of 4K resolution in this game.

Measured FPS Breakdown

At 1920x1080, the full range of settings was tested. Low settings produce an average FPS of 118, which is the highest recorded in the entire dataset. Medium settings yield 79 FPS, with a minimum of 67 and a maximum of 91. High settings average 67 FPS, and Ultra settings average 51 FPS. The progression shows a clear step-down of 39 FPS from Low to Medium, 12 FPS from Medium to High, and 16 FPS from High to Ultra.

At 2560x1440, the averages are 81 FPS for Low, 54 FPS for Medium (with a minimum of 46 and maximum of 62), 46 FPS for High, and 35 FPS for Ultra. The delta between Low and Medium is 27 FPS, which is a significant drop. The difference between Medium and High is 8 FPS, and between High and Ultra is 11 FPS. The min FPS for Medium at 1440p is 46, which is notably higher than the average FPS for High at the same resolution, showing that the Medium preset offers a more consistent experience.

At 3840x2160, the performance is the weakest. Low settings average 48 FPS, Medium averages 32 FPS (with a minimum of 27 and maximum of 37), High averages 27 FPS, and Ultra averages 21 FPS. The gap between Low and Medium is 16 FPS, and the gap between Medium and High is 5 FPS. The Ultra preset's 21 FPS is just above a slideshow threshold, making it unsuitable for gameplay.

The data indicates that the gap between settings narrows as resolution increases. At 1080p, the difference between Low and Ultra is 67 FPS. At 1440p, it is 46 FPS. At 4K, it is 27 FPS. This narrowing suggests that at higher resolutions, the GPU's pixel throughput becomes the dominant constraint, making the choice of preset less impactful on overall FPS.

CPU Role

The Intel Core i5-12400 provides the processing foundation for this combo. It has 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The CPU is based on the Alder Lake architecture and is manufactured on a 10 nm process. Its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache.

The CPU's benchmark scores show a balanced profile. In Cinebench R23, it scores 15989 in multi-core and 2257 in single-core. The multi-core score is indicative of its ability to handle Rust's server-side and simulation tasks, which can be CPU-intensive. The single-core score of 2257 is strong and helps with game logic that is often single-threaded. The 3DMark tests show a score of 5890 for max threads and 910 for single thread, which aligns with its core count and clock speeds.

The CPU's percentile rank versus all CPUs is 72, placing it in the upper tier of processors. Its average benchmark score is 18683, which is nearly identical to its nearest rivals. The data shows it is 0.1% behind the AMD EPYC 7643 and 0.9% ahead of the Intel Core i3-14100F. This indicates that the i5-12400 is a mid-range performer that does not significantly bottleneck the GPU in most scenarios.

In the context of Rust, the CPU's role is evident in the 1080p results. The high FPS at Low settings suggests that the CPU can handle the game's tick rate and entity updates without becoming a limiting factor. However, at 4K, the CPU's performance is masked by the GPU's inability to render frames quickly enough. The CPU's 65 W TDP suggests it is efficient, but the data does not show any thermal throttling effects, as the boost clock of 4.40 GHz is likely sustained.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of the Intel Core i5-12400 and Intel Arc B570 ranks 2349 out of 2953 total combos. This places it in the lower half of all tested systems, which is consistent with the measured FPS data showing it is not a top-tier performer. The rank of 2349 indicates that a majority of other CPU-GPU pairings deliver higher frame rates in this game.

The combo's ranking is likely influenced by the GPU's performance ceiling, as the CPU is a capable mid-range part. The Arc B570's 65th percentile ranking among all GPUs suggests it is an average performer, and when combined with a CPU that ranks in the 72nd percentile, the system is not optimized for maximum frame rates. The rank of 2349 out of 2953 means that roughly 79% of tested combos perform better in Rust, which is a significant margin.

This low ranking does not negate the system's viability for 1080p gaming, where it achieves high frame rates on Low and Medium settings. However, for users seeking high-refresh-rate 4K or maxed-out Ultra settings, this combo will fall short. The data suggests that this pairing is best suited for 1080p or 1440p gaming with adjusted settings, and users should temper their expectations for higher resolutions based on the measured performance. The rank is a clear indicator that while the system is functional, it is not a performance leader in Rust.
