Resolution Scaling

The measured FPS data for Rust with this AMD Ryzen 5 5600GT + AMD Radeon RX 580 combo reveals a steep performance cliff as resolution climbs. At 1080p Low settings, the system delivers 75.3 FPS average. Moving to 1440p Low drops that to 51.3 FPS, a 31.9% reduction. At 4K Low, the average falls to 28.1 FPS, representing a 62.7% decrease from the 1080p Low figure. This scaling pattern is far from linear, and the magnitude of the drop between 1080p and 4K strongly indicates that the GPU is the primary limiting factor once resolution increases.

The pattern holds across all quality settings. At High settings, the 1080p average of 40.4 FPS falls to 31.8 FPS at 1440p and then to 17 FPS at 4K. The 4K High result is less than half of the 1080p High result. Medium settings show a similar trajectory: 48.6 FPS at 1080p, 34.1 FPS at 1440p, and 21.8 FPS at 4K. Ultra settings are the most demanding, with 34.6 FPS at 1080p, 20.3 FPS at 1440p, and a barely playable 14.3 FPS at 4K.

The resolution scaling data suggests that at 1080p, the combination of the 6-core CPU and the GPU is more balanced, but as pixel count increases, the GPU's shading throughput and memory bandwidth become the bottleneck. The RX 580's 256.0 GB/s memory bandwidth and 6.175 TFLOPS FP32 performance are simply insufficient to maintain playable frame rates at 4K across any setting. At 1440p, the system is borderline for competitive play only on Low settings, while 1080p remains the only resolution where the combo can approach or exceed 60 FPS, and only on Low settings.

How This Combo Ranks

In Rust, this specific CPU-GPU combination ranks 1577 out of 1717 tested combos. This places it in the bottom 8.2% of all configurations, meaning 140 of every 1717 combos perform worse. The rank is a composite measure that reflects both the CPU's and GPU's individual capabilities and their interaction in this specific game.

The CPU's individual percentile rank is 78, meaning it outperforms 78% of all CPUs in the database's aggregate benchmarks. The GPU's percentile rank is 53, placing it almost exactly in the middle of all GPUs. The combination of a strong CPU and a middling GPU results in a combo rank that is dragged down by the GPU's limitations in Rust, which appears to be heavily GPU-bound at most settings and resolutions tested.

The gap between the CPU's high percentile and the combo's low rank is telling. It indicates that the Ryzen 5 5600GT has substantial headroom that the RX 580 cannot exploit in this title. A more capable GPU would likely shift this combo's rank significantly upward, as the CPU-side data suggests it is not the constraining factor in most of the measured scenarios. The 1577th rank out of 1717 is a clear signal that this pairing is unbalanced for Rust, with the GPU holding back the overall experience.

CPU Role

The AMD Ryzen 5 5600GT brings 6 cores and 12 threads based on the Zen 3 architecture, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. This is a 7 nm part from TSMC with 16 MB of L3 cache, and it supports DDR4 memory in dual-channel configuration. The CPU's aggregate benchmark scores are strong: Cinebench R23 multicore reaches 17,272, single-core 2,438; Geekbench multicore is 7,986, single-core 2,035. The 3DMark single-thread score is 913, and the max-threads score is 5,554.

In Rust, the CPU's role is to handle game logic, entity updates, and the simulation of the persistent world. The measured FPS data shows that at 1080p Low, the system achieves 75.3 FPS, which is the highest result across all configurations. This is likely near the CPU's practical limit for this game, given that lowering resolution further would not increase FPS if the CPU were saturated. However, the fact that 1080p Ultra still yields 34.6 FPS suggests the CPU can push more frames when the GPU is not the bottleneck.

The CPU's nearest rivals in aggregate performance are the Intel Core i7-10700 (average score 20,746, delta 0%), the Intel Core i5-12490F (20,794, -0.3%), and the AMD Ryzen 5 5600X (20,680, +0.3%). The Ryzen 5 5600GT's average benchmark score is 20,740, putting it in a virtual tie with the i7-10700 and just fractions of a percent away from the other two. This indicates that in CPU-bound scenarios, this processor performs on par with several well-regarded mid-range and older high-end parts.

The 12 threads are relevant for Rust, which can utilize multiple cores for background simulation tasks. The data shows the CPU is not the primary limiter at 1440p and 4K, as FPS drops dramatically with resolution increases regardless of settings. At 1080p High, the 40.4 FPS result versus 75.3 FPS at Low indicates that GPU load is still dominant, but the CPU maintains a playable floor even at Ultra settings (34.6 FPS).

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 75.3 FPS, which is the only configuration that approaches a smooth 60+ FPS experience. Medium settings drop to 48.6 FPS, High to 40.4 FPS, and Ultra to 34.6 FPS. The spread from Low to Ultra is 40.7 FPS, indicating that quality settings have a substantial impact on performance at this resolution.

At 2560x1440, the averages are significantly lower. Low settings yield 51.3 FPS, which is still playable for most users. Medium falls to 34.1 FPS, High to 31.8 FPS, and Ultra to 20.3 FPS. The drop from 1080p Low to 1440p Low is 24 FPS, while the drop from 1080p Ultra to 1440p Ultra is 14.3 FPS. The relative penalty is larger at lower settings, which is consistent with the GPU becoming the bottleneck as resolution increases.

At 3840x2160, the results are largely unplayable. Low settings average 28.1 FPS, Medium 21.8 FPS, High 17 FPS, and Ultra 14.3 FPS. Even the best 4K result (Low) is below 30 FPS, and Ultra dips into the low teens. The difference between 1080p Low and 4K Low is 47.2 FPS, a 62.7% reduction. Between 1080p Ultra and 4K Ultra, the reduction is 20.3 FPS, or 58.7%. The data shows that 4K is not a viable resolution for this combo in Rust, regardless of settings.

The settings scaling within each resolution also reveals the GPU's limits. At 1080p, going from Low to Medium costs 26.7 FPS, from Medium to High costs 8.2 FPS, and from High to Ultra costs 5.8 FPS. The diminishing returns suggest that the first step up from Low is the most demanding, while the higher settings have more similar costs. At 1440p, the Low-to-Medium drop is 17.2 FPS, Medium-to-High is 2.3 FPS, and High-to-Ultra is 11.5 FPS. At 4K, Low-to-Medium costs 6.3 FPS, Medium-to-High costs 4.8 FPS, and High-to-Ultra costs 2.7 FPS, showing that the GPU is so saturated that quality settings have less relative impact.

GPU Role

The AMD Radeon RX 580 is built on the Polaris 20 chip using GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It has 2,304 shading units, 144 texture mapping units, and 32 ROPs. The core runs at 1257 MHz base and 1340 MHz boost, while the 8 GB of GDDR5 memory operates at 2000 MHz with an 8 Gbps effective rate across a 256-bit bus, yielding 256.0 GB/s of bandwidth. The GPU's compute throughput is 6.175 TFLOPS for both FP32 and FP16 (1:1), and its pixel rate is 42.88 GPixel/s with a texture rate of 193.0 GTexel/s.

In Rust, the GPU's role is to render the environment, handle lighting and shadows, and process the volumetric effects that the game is known for. The measured FPS data shows that the RX 580 is the dominant bottleneck at 1440p and 4K. The GPU's average benchmark score is 13,559, with a passmark G3D score of 8,813 and a DirectX 12 score of 43. Its nearest rivals include the NVIDIA GeForce GTX 570 (average score 13,564, delta 0%), the NVIDIA GeForce GTX 950 (13,549, +0.1%), and the AMD Radeon Pro 455 (13,416, +1.1%). These scores place the RX 580 in the 53rd percentile of all GPUs, meaning it is a median performer.

The 8 GB VRAM is sufficient for Rust at 1080p and 1440p, as the game's texture requirements are unlikely to exceed this capacity at the tested settings. However, the GPU's raw compute power is the limiting factor. At 1080p Low, the 75.3 FPS result shows the GPU can keep up with the CPU when load is light. But as settings and resolution increase, the 6.175 TFLOPS and 256.0 GB/s bandwidth are insufficient to maintain frame rates above 35 FPS at 1080p Ultra or above 20 FPS at 1440p Ultra. The 4K results, with a maximum of 28.1 FPS on Low, confirm that this GPU is not designed for high-resolution gaming in modern titles like Rust.
