Rust

The AMD Ryzen 7 5700X3D paired with the Intel Arc B390 presents a highly unusual configuration for Rust, a game known for its demanding survival mechanics and large-scale multiplayer environments. The benchmark data reveals a system where the CPU is a high-performing desktop part, while the GPU is an integrated-class solution based on its specifications and benchmark percentile. The measured frame rates across all resolutions and settings indicate that this combination is severely constrained by the graphics processor, resulting in a gameplay experience that is largely below the threshold for smooth, competitive play.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern of performance degradation as resolution increases, but the rate of this decline is steep and indicative of a GPU-bound scenario. At 1080p with Low settings, the system achieves an average of 76 FPS. This is the highest performance point recorded in the entire dataset. Moving to 1440p at the same Low settings, the average FPS drops to 53, a significant reduction of 23 FPS (approximately 30%). At 4K, the average falls to 31 FPS, which is a further 22 FPS drop from the 1440p result and represents less than half the performance of the 1080p figure.

This scaling pattern is consistent across all settings presets. For example, at High settings, the average FPS goes from 43 at 1080p, to 30 at 1440p, and finally to 18 at 4K. Similarly, at Medium settings, the averages are 51, 35, and 21 FPS for 1080p, 1440p, and 4K respectively. The consistent and substantial FPS drops at each resolution step strongly suggest that the Intel Arc B390 is the primary limiting component. The frame rate is not holding steady or showing signs of a CPU bottleneck; instead, it is falling in near-linear proportion to the increase in pixel count, which is the classic signature of a graphics card that is overwhelmed by the rendering workload.

The data implies that at 1080p, the GPU is barely able to keep up with the CPU’s output, but as the resolution increases, the pixel fill rate and shading demands quickly outstrip the Arc B390's capabilities. The move from 1080p to 1440p is particularly punishing, with a ~30% performance hit, and 4K is largely unplayable at any setting, with averages ranging from 13 to 31 FPS. The limiting component is unequivocally the GPU, as the Ryzen 7 5700X3D has ample processing power to handle the game's simulation and physics, but the graphics pipeline is unable to deliver the frames.

FAQ

Q: What is the best performance I can expect from this system in Rust?

A: The highest measured average frame rate is 76 FPS, which occurs at 1920x1080 resolution with the Low settings preset. This is the only configuration in the measured data that approaches a level suitable for a responsive competitive experience, though it still falls short of high-refresh-rate monitors.

Q: Is this system capable of running Rust at 4K resolution?

A: The data shows that 4K performance is very poor. At 4K with Low settings, the average FPS is 31, but with Medium settings it drops to 21, and at Ultra it falls to 13 FPS. These results are not suitable for a playable experience in a demanding game like Rust.

Q: How does the Intel Arc B390 compare to its closest rivals in benchmark scores?

A: The Arc B390's average benchmark score is 1482. Its nearest rival, the NVIDIA GeForce GT 520MX, has an average score of 1463, which is 1.3% lower. Other close rivals include the NVIDIA GeForce 800M and GeForce GT 625 OEM, with the Arc B390 being 1.5% and 2.5% faster respectively.

Q: What is the impact of changing the graphics settings from Low to Ultra?

A: The impact is severe. At 1080p, the average FPS drops from 76 on Low to 33 on Ultra, a reduction of more than half. At 1440p, it drops from 53 to 23, and at 4K, it falls from 31 to 13. Higher settings demand significantly more from the GPU, which is already the system's bottleneck.

Its benchmark scores, such as a Cinebench R23 multicore score of 22366 and a Geekbench multicore score of 11086, place it in the 77th percentile of all CPUs. Its performance is nearly identical to the AMD Ryzen 5 7600X3D, which has an average score of 24728, just 0.1% higher.

Q: What is the overall rank of this CPU and GPU combination for this game?

A: The combination ranks 2601 out of 2953 tested combos for Rust. This places it in the bottom 12% of all tested systems, confirming that while the CPU is capable, the GPU drags the overall gaming performance down significantly.

GPU Role

The Intel Arc B390 is the decisive factor in this system's performance. Its specifications reveal a part designed for integrated graphics, not discrete gaming. It has a base clock of 300 MHz and a boost clock of 2500 MHz, with a TDP of just 80 W. Its memory configuration is "System Shared," meaning it relies on the system's main memory for both capacity and bandwidth, which is "System Dependent." This architecture is fundamentally different from a dedicated graphics card with its own high-speed VRAM and is a primary reason for the low frame rates observed.

The GPU's compute capabilities are limited, with an FP32 performance of 7.680 TFLOPS and a pixel rate of 60.00 GPixel/s. These figures place it in the 9th percentile of all GPUs, indicating it is far weaker than the vast majority of dedicated graphics cards. This is corroborated by its nearest rivals, which are low-end parts like the NVIDIA GeForce GT 520MX and GeForce GT 710. The Arc B390 is only 2.7% faster than the GT 710 in the average benchmark score.

In the context of Rust, this means the GPU is unable to handle the game's rendering load efficiently. The benchmark results show that the GPU's limitations are the primary bottleneck. Even at the lowest resolution and settings, the system cannot achieve high frame rates, and the situation deteriorates quickly as demands increase. The lack of dedicated VRAM is a significant handicap for a game like Rust, which features large, detailed environments. The system's reliance on shared memory also likely contributes to performance inconsistencies, as the CPU and GPU compete for the same memory resources. The data makes it clear that this GPU is not suited for gaming at any of the tested quality levels.

Settings Recommendations

Given the performance data, the only viable settings preset for a somewhat playable experience is Low. At 1920x1080 with Low settings, the system achieves an average of 76 FPS. This is the only measured configuration that exceeds 60 FPS and could provide a reasonably smooth experience on a standard 60Hz monitor. All other settings at 1080p result in averages below 60 FPS, with Medium at 51 FPS and High at 43 FPS.

At 1440p, the situation is more challenging. The Low preset yields an average of 53 FPS, which is playable but not ideal. The Medium preset drops to 35 FPS, which is uncomfortable for a fast-paced game, and High and Ultra are below 30 FPS. For 4K, none of the presets are recommended, as even the Low setting only produces an average of 31 FPS, with Ultra at 13 FPS.

The "best experience" per the measured rows is to run the game at 1080p with the Low settings preset. This is the only combination that provides a frame rate that is generally considered acceptable for playable performance. While a 76 FPS average is not high, it is the ceiling for this system. Attempting to use higher settings at 1080p or any settings at higher resolutions will result in a significant degradation of smoothness and responsiveness. The data suggests that users should prioritize frame rate over visual fidelity with this hardware configuration.

Measured FPS Breakdown

The following is a detailed breakdown of the measured average FPS for the AMD Ryzen 7 5700X3D and Intel Arc B390 combination in Rust.

At 1920x1080, the results are as follows:

• Low: 76 FPS average.
• Medium: 51 FPS average, with a minimum of 44 and a maximum of 59 FPS.
• High: 43 FPS average.
• Ultra: 33 FPS average.

At 2560x1440, the performance drops significantly:

• Low: 53 FPS average.
• Medium: 35 FPS average, with a minimum of 30 and a maximum of 41 FPS.
• High: 30 FPS average.
• Ultra: 23 FPS average.

At 3840x2160, the system is severely constrained:

• Low: 31 FPS average.
• Medium: 21 FPS average, with a minimum of 18 and a maximum of 24 FPS.
• High: 18 FPS average.
• Ultra: 13 FPS average.

The data shows a clear and consistent hierarchy. The only playable performance is found at 1080p Low. Every other configuration is either borderline or unplayable. The Medium preset at 1080p is the only other option that provides an average above 50 FPS, but its minimum of 44 FPS suggests it will have noticeable stutters. The results at 1440p and 4K are not recommended for any serious gameplay.

CPU Role

The AMD Ryzen 7 5700X3D is a stark contrast to the GPU. It is an 8-core, 16-thread processor based on the Zen 3 architecture. It has a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its most distinctive feature is its large 96 MB shared L3 cache, which is a key attribute for gaming performance. The CPU's benchmark scores are strong, with a Cinebench R23 multicore score of 22366 and a Geekbench single-core score of 1849.

Its average benchmark score of 24709 places it in the 77th percentile of all CPUs. This is a high-ranking position, and its nearest rivals are all close in performance. The AMD Ryzen 5 7600X3D has a nearly identical average score of 24728, which is only 0.1% higher. The Intel Core i5-12450HX and Intel Core i5-11600 are also within 0.6% of its score. This indicates that the CPU is a very capable and balanced performer, certainly not a weak link in this system.

In Rust, the CPU is responsible for game simulation, entity logic, and network processing, tasks that benefit from the 8 cores and 16 threads. The large L3 cache is also beneficial for this type of workload, as it can reduce memory latency. The benchmark results suggest that the CPU is more than capable of feeding the GPU with data. However, because the Arc B390 is the bottleneck, the CPU's potential is never fully realized in the FPS data. The frame rates are consistently low across all settings, which would not be the case if the CPU were the limiting factor. The CPU's role is to provide the necessary processing power, but the GPU is unable to translate that into high frame rates.

How This Combo Ranks

The overall ranking for this specific combination in Rust is 2601 out of 2953 tested combos. This places the AMD Ryzen 7 5700X3D and Intel Arc B390 in the bottom 12% of all tested systems. This low ranking is a direct consequence of the GPU's very poor performance, as the CPU is a high-quality part.

This ranking is not surprising given the individual components. The CPU's percentile vs all CPUs is 77, indicating it is better than 77% of all processors. Conversely, the GPU's percentile vs all GPUs is 9, indicating it is better than only 9% of all graphics cards. The combination of a top-tier CPU with a bottom-tier GPU results in a system that is severely imbalanced for gaming. The CPU's processing power is wasted because the GPU cannot keep up.

The data shows that the system's performance is entirely dictated by the GPU. While the CPU would likely allow for high frame rates with a more powerful graphics card, the Arc B390 holds the entire system back. The rank of 2601 out of 2953 reflects this reality, confirming that this is a configuration that is not suited for playing Rust at a satisfactory level. The combo's position reflects the critical importance of a balanced system, where the GPU's capabilities must be sufficient to match the CPU's potential. In this case, the massive disparity between the two components results in a very poor gaming experience.
