Rust

The AMD Ryzen 5 4600G and NVIDIA GeForce RTX 4080 SUPER pairing in Rust delivers a performance profile that is heavily dictated by resolution, with the CPU proving to be the limiting factor at lower resolutions while the GPU takes over at 4K. The data shows a clear hierarchy where the RTX 4080 SUPER’s immense power is only fully utilized when the resolution increases, making this a combo that scales unusually well with display resolution but leaves performance on the table at 1080p.

Resolution Scaling

The measured FPS data reveals a dramatic shift in performance scaling as resolution increases, pointing directly to where the bottleneck lies. At 1080p with Low settings, the combo achieves 154.5 FPS, but this drops by 16.8% to 138.3 FPS at 1440p, and then by an additional 17.1% to 114.6 FPS at 4K. This relatively modest decline from 1080p to 4K—a total drop of 25.8%—indicates that at 1080p, the system is not fully GPU-bound; the processor is holding back the frame rate.

The pattern becomes even more telling at High settings. At 1080p High, the average FPS is 126.5. Moving to 1440p High reduces this to 111.1 FPS (a 12.2% drop), and at 4K High, the system produces 64.3 FPS (a 42.1% drop from 1440p). The steep decline between 1440p and 4K at High settings shows that the GPU is finally becoming the limiting component at the highest resolution, as the rendering load overwhelms the CPU’s ability to feed it.

At Ultra settings, the trend is even more pronounced. The 1080p Ultra result is 117 FPS, which is actually higher than the 1080p High result for many systems, but here it represents a 7.5% drop from High. At 1440p Ultra, the FPS falls to 82.5 (a 29.5% drop from 1080p Ultra), and at 4K Ultra, it plummets to 51.7 FPS (a 37.3% drop from 1440p). This scaling pattern confirms that the RTX 4080 SUPER is the dominant factor at 4K, while the Ryzen 5 4600G’s limitations are exposed at 1080p where the GPU cannot stretch its legs.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is an absolute powerhouse, and its specifications in the data explain why it dominates at higher resolutions. With 16 GB of GDDR6X memory on a 256-bit bus, it offers 736.3 GB/s of bandwidth, which is critical for Rust’s large, open-world textures and draw distances. The GPU’s boost clock of 2550 MHz, paired with 10240 shading units and 80 RT cores, provides the raw compute needed to handle the game’s lighting and physics at 4K.

The GPU’s benchmark scores corroborate its high-end status. It achieves a Passmark G3D score of 34245 and a 3DMark Steel Nomad DX12 score of 6600, placing it in the 88th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489, which is a 0.2% deltaPct, meaning the RTX 4080 SUPER is effectively tied with it in synthetic tests. However, in Rust, the data shows the 4080 SUPER’s strengths are best utilized at 4K, where it maintains playable frame rates even at High settings.

The memory configuration is particularly relevant. At 4K Ultra, the combo drops to 51.7 FPS, which is likely a result of the GPU’s memory bandwidth being taxed by the highest texture quality. The 16 GB frame buffer is sufficient, but the 736.3 GB/s bandwidth is the limiting factor at Ultra, not the capacity. At 4K Low, the FPS jumps to 114.6, showing that when texture and shading loads are reduced, the GPU has ample headroom to push frames.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. It features 8 MB of shared L3 cache and supports DDR4 memory with a bandwidth of 51.2 GB/s. In synthetic benchmarks, it scores 13593 in Cinebench R23 multicore and 1919 in single-core, placing it in the 75th percentile of all CPUs.

The CPU’s role in Rust is revealed by the FPS gaps at lower resolutions. At 1080p Low, the combo hits 154.5 FPS, but this is far below what the RTX 4080 SUPER is capable of. The CPU’s single-thread performance, as indicated by its 726 score in 3DMark single-thread, is the bottleneck here. Rust is known for its CPU-intensive simulation, and the 4600G’s Zen 2 cores cannot feed the GPU fast enough at 1080p.

The nearest rival data shows the 4600G is competitive with the Intel Core i3-13100F, which has a deltaPct of -1, meaning the 4600G is about 1% faster in average benchmark scores. However, the 4600G’s 6 cores and 12 threads provide more headroom for multitasking, but in Rust’s single-threaded scenarios, it struggles to push beyond the 150 FPS mark. At 1440p and 4K, the CPU’s limitations become less apparent because the GPU takes longer to render each frame, allowing the CPU to keep up.

FAQ
