Rust

The AMD Ryzen 5 5500X3D paired with the Intel Arc B370 presents a unique dataset for Rust, a survival title known for its demanding simulation and rendering loads. The measured results show a system that is fundamentally constrained by its graphics solution, with the CPU’s substantial cache providing a strong foundation that the GPU cannot fully utilize. The data reveals a consistent pattern: as resolution increases, frame rates fall dramatically, indicating that the Intel Arc B370 is the primary bottleneck across all tested settings.

Resolution Scaling

The FPS data shows a clear and steep decline as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 69 FPS at 1080p to 48 FPS at 1440p, and then to 28 FPS at 4K. This represents a 30% decrease from 1080p to 1440p, and a further 42% decrease from 1440p to 4K. The pattern is consistent across all quality presets, though the absolute numbers change.

At Medium settings, the average FPS falls from 46 at 1080p to 32 at 1440p, then to 19 at 4K. High settings show a similar trajectory: 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K. The Ultra preset, which is the most demanding, shows the lowest absolute numbers, with averages of 30 FPS at 1080p, 20 FPS at 1440p, and just 12 FPS at 4K.

The scaling behavior indicates that the limiting component is the GPU. If the CPU were the bottleneck, we would expect to see a smaller difference between 1080p and 4K, as the resolution increase would put more load on the graphics card while the CPU load remains relatively constant. Instead, the frame rate nearly halves when moving from 1080p to 4K at every setting level, which is a classic sign of a GPU that is saturated by pixel throughput demands. The 4K results are particularly telling, with even the Low preset only achieving 28 FPS, suggesting that the Intel Arc B370 cannot handle the pixel count of 3840x2160 in this title.

Settings Recommendations

Given the measured data, the optimal settings depend heavily on the target resolution and desired frame rate. At 1920x1080, the Low preset provides the best playable experience with an average of 69 FPS. This is the only configuration that approaches the 60 FPS threshold, which is generally considered the minimum for smooth gameplay. The Medium preset at 1080p yields 46 FPS, which is playable but may exhibit noticeable stutters in fast-paced scenarios.

For users prioritizing visual quality over raw frame rate, the High preset at 1080p offers a compromise at 39 FPS, but the data suggests this is a significant sacrifice in smoothness for marginal visual gains. The Ultra preset at 1080p, at 30 FPS, is not recommended for active play, as the frame pacing will likely feel sluggish. At 2560x1440, the Low preset is the only viable option, achieving 48 FPS, while Medium drops to 32 FPS and High falls to 27 FPS.

The 3840x2160 resolution is not viable for this combination. Even the Low preset, which is the least demanding, only achieves 28 FPS. The Medium preset has a recorded minimum of 16 FPS, which indicates severe frame drops that would make the game unresponsive. The data suggests that users should stick to 1080p with Low settings to achieve a consistent frame rate, or accept lower performance at higher resolutions with reduced quality presets. The measured rows show a clear trade-off: every step up in quality costs a significant number of frames.

GPU Role

The Intel Arc B370 is the dominant factor in this system's Rust performance. Its specifications reveal why it struggles with this game. The GPU has 1280 shading units, 40 texture mapping units, and 20 raster output units, with a boost clock of 2400 MHz. Its memory is listed as "System Shared," which means it relies on the system's main memory rather than dedicated VRAM. This shared memory configuration is a major disadvantage in a game like Rust, which has large textures and complex environments that require fast, dedicated memory access.

The GPU's compute capabilities are modest, with an FP32 performance of 6.144 TFLOPS. The data shows that this raw compute power is insufficient for the demands of Rust at higher resolutions. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are theoretical maximums that are unlikely to be sustained in real-world scenarios, given the frame rate results. The 3DMark Steel Nomad benchmark score of 1184 places this GPU in the 5th percentile of all GPUs, and its nearest rivals are older integrated and entry-level discrete cards like the ATI Mobility Radeon HD 5570 and the AMD Radeon HD 7650M.

The fact that the GPU's VRAM is "System Shared" and its bandwidth is "System Dependent" means that performance can vary based on the system's memory configuration. This is a critical limitation, as Rust's open-world environments require constant streaming of assets. The measured FPS data supports this interpretation: the GPU is unable to maintain playable frame rates even at 1080p with higher settings, indicating that its memory bandwidth and processing power are not sufficient for the game's requirements. The GPU's TDP is just 25 W, which classifies it as an integrated graphics processor (IGP), further confirming that it is not designed for demanding gaming workloads.

CPU Role

The AMD Ryzen 5 5500X3D is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.00 GHz and a boost clock of 4.00 GHz. Its defining feature is the 96 MB of shared L3 cache, which is significantly larger than typical processors in its class. This cache is designed to improve gaming performance by storing frequently accessed data closer to the cores. The CPU's benchmark results show a Passmark single-thread score of 2941 and a multithread score of 20363, placing it in the 85th percentile of all CPUs.

The CPU's nearest rivals in benchmark scores include the AMD Ryzen 5 5600F, which scores 0.2% higher, and the Intel Core i9-12900T, which scores 0.3% lower. This indicates that the 5500X3D is a competitive processor in synthetic benchmarks, but the game's actual performance is not limited by the CPU. The measured FPS data shows that even at 1080p Low, where the CPU would typically have the most influence, the system only achieves 69 FPS. This is far below what the CPU's capabilities suggest it could deliver if paired with a more powerful GPU.

In Rust, the CPU handles game logic, entity updates, and physics calculations. The large L3 cache should help with the game's many small data structures and frequent memory accesses. However, the data indicates that the GPU is the limiting factor. The frame rates do not improve significantly when the resolution is lowered, which would be expected if the CPU were the bottleneck. Instead, the frame rates scale directly with resolution, confirming that the CPU has headroom left unused. The CPU's TDP of 105 W and support for ECC memory suggest it is a capable desktop processor, but its potential is wasted in this pairing for Rust.

Measured FPS Breakdown

The complete dataset for Rust provides a comprehensive view of the system's performance. At 1920x1080, the Low preset achieves an average of 69 FPS. The Medium preset averages 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS. The High preset averages 39 FPS, and the Ultra preset averages 30 FPS. The Medium preset's min/max range shows a variance of 14 FPS, indicating some inconsistency in frame delivery.

At 2560x1440, the Low preset averages 48 FPS. The Medium preset averages 32 FPS, with a minimum of 27 FPS and a maximum of 37 FPS. The High preset averages 27 FPS, and the Ultra preset averages 20 FPS. The delta between Low and Ultra at this resolution is 28 FPS, showing the significant cost of higher quality settings.

At 3840x2160, the Low preset averages 28 FPS. The Medium preset averages 19 FPS, with a minimum of 16 FPS and a maximum of 22 FPS. The High preset averages 16 FPS, and the Ultra preset averages 12 FPS. The data shows that at 4K, even the lowest settings fail to reach 30 FPS, making the game effectively unplayable.

The pattern across all resolutions is consistent: moving from Low to Ultra roughly halves the frame rate. For example, at 1080p, the drop is from 69 to 30 FPS, a 57% reduction. At 1440p, the drop is from 48 to 20 FPS, a 58% reduction. At 4K, the drop is from 28 to 12 FPS, a 57% reduction. This consistency suggests that the GPU's processing power scales linearly with the quality settings, and there are no unexpected bottlenecks or optimizations in the game engine that would alter this relationship.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of the AMD Ryzen 5 5500X3D and Intel Arc B370 ranks 2710 out of 2953 total combinations. This places it in the bottom 8% of all tested systems, which is consistent with the measured frame rates that are generally below playable thresholds except at the lowest settings and resolution.

The rank reflects the significant imbalance between the CPU and GPU. While the CPU is in the 85th percentile of all processors, the GPU is in the 5th percentile of all GPUs. This creates a situation where the system's overall performance is dragged down by its weakest component. The benchmark data suggests that this combination would not be recommended for Rust, as even the best-case scenario of 69 FPS at 1080p Low is only marginally acceptable.

The rank of 2710 out of 2953 means that 243 other combinations performed worse in this game. However, the vast majority of tested systems outperformed this pairing. The data indicates that the Intel Arc B370 is the primary reason for the low ranking, as its shared memory architecture and low compute throughput cannot handle the demands of Rust's rendering pipeline. The CPU, despite its strong gaming-oriented cache design, cannot compensate for the GPU's limitations in this title.
