Rust

The AMD Ryzen 5 5500 and AMD Radeon RX 6800 XT pairing in Rust produces a dataset that reveals a system heavily influenced by both its components, but with the GPU taking the lead in defining the experience. With a combo rank of 578 out of 1717 tested configurations, this setup sits in the upper third of all pairings, indicating a solidly capable machine for the survival title. The measured FPS across resolutions and settings shows a predictable pattern of scaling, but the magnitude of those drops and gains tells a story about where the bottlenecks and strengths lie.

Resolution Scaling

The FPS data from 1080p to 4K shows a clear and significant impact from resolution, which is the hallmark of a GPU-bound scenario. At 1080p with Low settings, the system achieves an average of 181.3 FPS, but this drops to 142 FPS at 1440p and further to 87.3 FPS at 4K. This represents a 52% reduction in average FPS from 1080p to 4K at Low settings, a substantial hit that points directly at the rendering pipeline being the primary limiter.

However, the scaling is not uniform across all settings. At Ultra settings, the drop from 1080p (89.2 FPS) to 1440p (60.1 FPS) is a 33% decrease, and then to 4K (37.9 FPS) is another 37% decrease from 1440p. The relative performance loss is slightly more pronounced at lower settings because the CPU is more capable of keeping up, allowing the GPU to become the sole constraint. At 4K Ultra, the system manages only 37.9 FPS, which suggests that the RX 6800 XT, while powerful, is being pushed to its limits with the most demanding visual configuration.

The data implies that the limiting component at lower resolutions and settings is more likely the CPU, as the FPS at 1080p Low (181.3) is high enough to suggest the GPU is not fully saturated. Conversely, at 4K, the GPU is clearly the bottleneck, as the FPS drops are steep and consistent with the increased pixel count. The transition from 1440p to 4K at Medium settings (94.1 to 55.6 FPS) shows a 41% drop, reinforcing that the GPU’s workload is the dominant factor at higher resolutions.

GPU Role

The Radeon RX 6800 XT’s role in this benchmark is defined by its 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. This is a generous amount of VRAM for a game like Rust, which is known for its large maps and frequent texture streaming. The 16 GB capacity likely prevents any VRAM-related stuttering or texture pop-in, allowing the measured FPS to be driven purely by compute and rasterization performance.

The GPU’s clock speeds, with a base of 1825 MHz and a boost of 2250 MHz, are respectable for the RDNA 2 architecture. The game clock of 2015 MHz represents the typical sustained frequency during gaming workloads. The high boost clock contributes to the strong performance seen at 1080p and 1440p, where the GPU can operate closer to its maximum potential. The fact that the 4K Ultra result falls to 37.9 FPS is not a memory issue but purely a computational one, as the 4608 shading units are tasked with processing a massive number of pixels.

The GPU’s percentile ranking of 87 against all GPUs, with an average benchmark score of 49982, places it well above the median. Its closest rivals include the NVIDIA GeForce RTX 4070 Ti SUPER (2.6% higher avg score) and the Intel Arc A550M (0.5% higher), showing that the RX 6800 XT is competitively positioned. In Rust specifically, the measured FPS suggests the GPU is the primary driver of performance at 4K, while at 1080p, the headroom is significant enough that the CPU becomes more relevant.

How This Combo Ranks

The combined rank of 578 out of 1717 tested combos places this Ryzen 5 5500 and RX 6800 XT setup in the 66th percentile of all configurations tested. This is a strong result, indicating that the pairing is well-balanced for Rust, though not at the absolute top tier. The CPU itself ranks in the 79th percentile of all CPUs, with an average benchmark score of 20875, which is nearly identical to its nearest rival, the Intel Core i5-12500 (20897, deltaPct -0.1). The GPU ranks in the 87th percentile of all GPUs.

This combination of a top-quartile GPU with a slightly below-top-quartile CPU results in a system that is more GPU-leaning in its performance profile. The data suggests that the CPU is not holding back the GPU significantly at higher resolutions, but at 1080p Low, the 181.3 FPS result may be closer to the CPU’s limit than the GPU’s. The overall rank of 578 indicates that while there are many better-performing combos (primarily those with higher-end CPUs), this setup is more than capable of delivering a smooth experience in most scenarios.

Measured FPS Breakdown

At 1920x1080, the average FPS scales from 181.3 (Low) to 137.9 (Medium), 116.7 (High), and 89.2 (Ultra). The gap between Low and Ultra is 92.1 FPS, showing that settings have a massive impact at this resolution. The 1440p results follow a similar pattern: 142 FPS (Low), 94.1 (Medium), 80.4 (High), and 60.1 (Ultra). The drop from Low to Ultra at 1440p is 81.9 FPS, which is slightly less than at 1080p, indicating the GPU is starting to become more of a limiting factor.

At 3840x2160, the results are 87.3 FPS (Low), 55.6 (Medium), 50.8 (High), and 37.9 (Ultra). The difference between Low and Ultra at 4K is 49.4 FPS, a smaller absolute gap but a larger percentage drop (57%). This confirms that at 4K, the GPU is the dominant constraint, and even reducing settings to Low cannot push the FPS above 90. For a competitive or fast-paced experience, 1080p Low at 181.3 FPS is clearly the best option, while 4K Ultra at 37.9 FPS is only viable for slower, more cinematic play.

CPU Role

The AMD Ryzen 5 5500 is a 6-core, 12-thread processor based on the Zen 3 architecture (Cezanne codename) with a base clock of 3.60 GHz and a boost of 4.20 GHz. Its benchmark scores show a strong single-thread performance (Cinebench R23 single-core score of 2319) and solid multi-thread capabilities (Cinebench R23 multi-core score of 16429). The CPU’s percentile rank of 79 places it above average, but its nearest rivals, such as the Intel Core i5-12500, are nearly identical in average score (20897 vs 20875, a deltaPct of -0.1).

In Rust, the CPU’s role becomes more apparent at lower resolutions. The jump from 1080p Low (181.3 FPS) to 1440p Low (142 FPS) is a 22% drop, which is less than the jump from 1440p Low to 4K Low (87.3 FPS, a 39% drop). This suggests that at 1080p, the CPU is able to feed the GPU sufficiently, but the GPU still has headroom. The 16 MB of L3 cache is modest for a modern CPU, but the 12 threads help with Rust’s background simulation tasks. The single-thread score of 2319 in Cinebench R23 indicates that the CPU can handle the game’s primary logic thread, but it is not a top-tier performer, which is consistent with its rank and the overall combo performance.

Settings Recommendations

Based on the measured data, the best experience depends on the target resolution and refresh rate. For 1080p displays, Low settings provide the highest average FPS at 181.3, which is ideal for high-refresh-rate monitors. Medium settings at 137.9 FPS are still very smooth and offer a better visual balance, while High at 116.7 FPS is also viable. Ultra at 89.2 FPS is playable but may not be optimal for competitive play.

At 1440p, Low settings (142 FPS) are the clear choice for maximum fluidity. Medium (94.1 FPS) and High (80.4 FPS) are solid options for a more visually rich experience without sacrificing too much performance. Ultra at 60.1 FPS is borderline, but it hits the 60 FPS threshold for a consistent console-like experience.

At 4K, the data points to Low settings (87.3 FPS) as the only configuration that offers a consistently smooth experience. Medium (55.6 FPS) and High (50.8 FPS) are playable but will have noticeable frame pacing issues. Ultra (37.9 FPS) is not recommended for any serious gameplay, as it falls below standard playability thresholds. The best overall recommendation for a balanced experience is 1440p Medium, which offers a 94.1 FPS average, providing a good mix of visual fidelity and performance without pushing the GPU to its limits.
