Rust

The AMD Ryzen 5 2600 paired with the Intel Arc B580 produces a highly resolution-sensitive experience in Rust, with performance scaling that clearly identifies the GPU as the primary constraint at higher resolutions while the CPU takes on a more significant role at 1080p. The measured data shows a wide spread between the lowest and highest settings, making preset selection crucial for playability.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a dramatic reduction in frame rate across every settings preset, indicating that the Intel Arc B580's rendering pipeline becomes the dominant bottleneck as pixel count increases. At Low settings, the average frame rate drops from 131 FPS at 1080p to 92 FPS at 1440p, a 30% reduction, and then falls further to 54 FPS at 4K, representing a 59% loss compared to the 1080p result. This scaling pattern is consistent with a GPU that is being pushed to its limits by the higher pixel throughput required at 4K resolution.

Medium settings show a similar trend, with averages of 89 FPS at 1080p, 61 FPS at 1440p, and 36 FPS at 4K. The drop from 1440p to 4K is particularly steep at 41%, suggesting that the memory bandwidth of 456.0 GB/s and the 12 GB GDDR6 frame buffer are being saturated by the combination of increased resolution and moderate graphical complexity. High settings follow the same trajectory, with 75 FPS at 1080p, 52 FPS at 1440p, and 31 FPS at 4K, while Ultra settings produce the most severe scaling, falling from 57 FPS at 1080p to 39 FPS at 1440p and finally to 23 FPS at 4K.

The resolution scaling data indicates that the sweet spot for this combination is 1080p, where even Ultra settings maintain an average above 57 FPS. At 1440p, only Low and Medium settings remain playable, with High dipping to 52 FPS and Ultra dropping below 40 FPS. The 4K results are uniformly below 60 FPS for all presets, with the highest average being 54 FPS at Low settings, which suggests that 4K gaming is only viable with significant graphical compromises on this hardware configuration.

GPU Role

The Intel Arc B580's role in these results is defined by its core specifications: 2560 shading units operating at a boost clock of 2670 MHz, paired with 12 GB of GDDR6 memory on a 192-bit bus delivering 456.0 GB/s of bandwidth. The GPU's pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s provide the theoretical foundation for the measured frame rates, but the actual performance in Rust demonstrates that these capabilities are stretched thin at higher resolutions.

The GPU's benchmark scores place it in the 68th percentile versus all GPUs, with an average benchmark score of 23021. Its nearest rivals include the AMD Radeon RX 580 2048SP, which scores 23061 and is only 0.2% faster, and the NVIDIA GeForce RTX 2080, which scores 22895 and is 0.6% slower. The NVIDIA GeForce RTX 3080 scores 23172, which is 0.7% faster than the Arc B580, indicating that this Intel GPU performs in a similar tier to those established cards despite being a newer architecture.

The 12 GB memory capacity is sufficient for Rust's demands at all tested resolutions, as evidenced by the fact that frame rates scale predictably with resolution rather than exhibiting sudden drops that would indicate memory exhaustion. The 456.0 GB/s bandwidth becomes a limiting factor at 4K, where the Ultra preset's average of 23 FPS suggests that the GPU cannot efficiently feed the rendering pipeline at that pixel load. At 1080p, the GPU's capabilities are more than adequate, with the Low preset achieving 131 FPS, which indicates that the rendering pipeline is not the primary constraint at that resolution.

CPU Role

The AMD Ryzen 5 2600 contributes to the measured results through its 6 cores and 12 threads, running at a base clock of 3.40 GHz and a boost clock of 3.90 GHz. This CPU represents the Zen+ architecture on a 12 nm process, with 16 MB of shared L3 cache and support for dual-channel DDR4 memory at 46.9 GB/s bandwidth. The CPU's benchmark scores show a multi-threaded performance that is competitive with its nearest rivals, including the Intel Core Ultra 5 228V, which scores 21440 and is 0.2% slower, and the Intel Core i9-11900H, which scores 21367 and is 0.5% slower.

The CPU's percentile ranking of 75 versus all CPUs indicates that it sits above the median in overall processing capability, with an average benchmark score of 21484. However, its single-thread performance, as measured by Geekbench at 1154 points, is more modest, and this becomes relevant at 1080p where the CPU must feed frames to the GPU at higher rates. The data shows that at 1080p Low settings, the system achieves 131 FPS, which is the highest measured average across all configurations, suggesting that the CPU can keep up with the GPU's output at this resolution.

The CPU's role becomes more apparent when examining the scaling from 1080p to 1440p. At Low settings, the frame rate drops from 131 FPS to 92 FPS, a 30% reduction, which is proportionally larger than the 33% increase in pixel count, indicating that the CPU is not the primary bottleneck at these settings. In contrast, at Ultra settings, the drop from 1080p to 1440p is from 57 FPS to 39 FPS, a 32% reduction, which is nearly proportional to the pixel increase, suggesting that the GPU is doing most of the work at these higher settings. The 6-core, 12-thread configuration provides adequate headroom for Rust's simulation and physics workloads, and the CPU's passmark physics score of 673 supports this assessment.
