Rust

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4080 SUPER combination delivers a comprehensive performance profile in Rust, placing 61st out of 1,717 tested combos. This pairing of a 12-core Zen 5 processor with an Ada Lovelace flagship GPU produces frame rates ranging from 47.5 FPS at 4K Ultra to 277.1 FPS at 1080p Low, demonstrating the game’s scalability across a wide spectrum of settings.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 9 9900X is built on the Zen 5 architecture (Granite Ridge) using a 4 nm process, featuring 12 cores and 24 threads. Its base clock of 4.40 GHz and boost clock of 5.60 GHz provide substantial single-thread throughput, which is critical for Rust’s simulation-heavy gameplay. The processor’s L3 cache totals 64 MB (shared), while L1 and L2 caches are 80 KB and 1 MB per core, respectively. This large cache hierarchy helps reduce memory latency in a game where entity updates and world persistence demand rapid data access.

The CPU’s benchmark data shows strong single-core performance, with a 3dmark single-thread score of 1,286 and a Cinebench R23 single-core score of 6,555. Multi-threaded results are equally robust: Cinebench R23 multi-core reaches 46,438, and Passmark multi-thread scores 54,643. In Rust, these scores translate to the processor’s ability to handle both the main game thread and background physics/network tasks without becoming a bottleneck at lower resolutions. The 9900X ranks in the 94th percentile among all CPUs, with an average benchmark score of 54,450.

The nearest rival comparison shows the 9900X is effectively tied with the AMD Ryzen 9 9900X3D (deltaPct -0.4) and Intel Core i7-14700F (deltaPct 0.7). It trails the Intel Core Ultra 5 245K by -1.5% and the Ultra 5 245KF by -1.8%. These small deltas indicate that the 9900X’s performance in synthetic tests is competitive with these alternatives, though its advantage in Rust will depend on how well the game leverages the CPU’s cache layout versus the 3D V-Cache of the X3D variant.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Ryzen 9 9900X paired with the RTX 4080 SUPER achieves a combo rank of 61 out of 1,717 tested combinations in Rust. This places it in the top 3.6% of all tested systems, indicating that this configuration is well above average for this title. The rank reflects the combined capability of both components, where the CPU’s high single-thread score and the GPU’s substantial rasterization power complement each other effectively.

Given the CPU’s 94th percentile standing and the GPU’s 88th percentile, the combo ranking at 61 suggests that Rust rewards the balance of these two parts. The 9900X’s 3dmark 16-thread score of 12,552 and max-thread score of 13,929 show that it can feed the GPU with enough draw calls and simulation data, while the RTX 4080 SUPER’s Passmark G3D score of 34,245 ensures that rendering output keeps pace. The fact that the combo ranks 61st rather than higher in the raw list is likely due to other tested configurations using faster CPUs with 3D V-Cache or more aggressive GPU variants, but the data shows this pairing delivers a smooth experience across the board.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern as resolution increases. At 1080p High, the combo produces 160.6 FPS; at 1440p High, it drops to 111.6 FPS; and at 4K High, it falls to 66.4 FPS. This represents a 58.6% reduction from 1080p to 4K at High settings. The same trend appears at Low settings: 277.1 FPS at 1080p, 198.3 FPS at 1440p, and 115.8 FPS at 4K, a 58.2% drop.

The scaling behavior indicates that the GPU becomes the limiting component at higher resolutions. At 1080p Low, the 277.1 FPS figure suggests the CPU is still capable of pushing beyond this, but the GPU is already working near its limits for the given settings. Moving to 4K Low, the 115.8 FPS result shows the RTX 4080 SUPER’s raw pixel throughput is the primary constraint. The RTX 4080 SUPER features 10,240 shading units, 320 TMUs, and 112 ROPs, with a boost clock of 2,550 MHz and FP32 performance of 52.22 TFLOPS. These specifications drive the frame rate at 4K, where pixel fill rate (285.6 GPixel/s) and texture rate (816.0 GTexel/s) become decisive.

In contrast, the CPU’s impact is more visible at 1080p, where the gap between Low and Ultra settings is 155.2 FPS (277.1 vs 121.9). This larger spread at lower resolutions suggests that the CPU can maintain high frame generation, but the GPU’s workload scales more steeply with settings. The data confirms that for Rust, the RTX 4080 SUPER is the bottleneck at 4K, while the Ryzen 9 9900X provides ample headroom at 1080p.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers its highest frame rates. Low settings yield 277.1 FPS, Medium drops to 195.2 FPS, High produces 160.6 FPS, and Ultra reduces performance to 121.9 FPS. The difference between Low and Ultra is 155.2 FPS, showing that settings adjustments have a profound effect on the GPU’s workload. The Ultra result remains above 120 FPS, indicating that high-refresh-rate 1080p monitors can be fully utilized even with maximum quality presets.

Moving to 2560x1440, the frame rates scale down proportionally. Low settings produce 198.3 FPS, Medium reaches 133 FPS, High hits 111.6 FPS, and Ultra drops to 86 FPS. The 1440p Ultra result of 86 FPS is still comfortably playable for competitive or survival gameplay, though the 42.4% drop from Low to Ultra at this resolution highlights the GPU’s sensitivity to settings. The High preset at 1440p (111.6 FPS) represents a balanced choice for smooth performance.

At 3840x2160, the GPU is clearly the limiting factor. Low settings achieve 115.8 FPS, Medium produces 77.8 FPS, High yields 66.4 FPS, and Ultra falls to 47.5 FPS. The 4K Ultra result barely reaches 48 FPS, which may not satisfy players seeking smooth motion on high-refresh displays. However, 4K Low at 115.8 FPS demonstrates that the RTX 4080 SUPER’s 16 GB of GDDR6X memory and 736.3 GB/s bandwidth can handle 4K rendering when quality presets are reduced. The step from Medium to High at 4K (77.8 to 66.4 FPS) shows a 14.6% penalty, while the jump to Ultra incurs a further 28.5% drop from High.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 SUPER is built on the Ada Lovelace architecture using a 5 nm process at TSMC, with the AD103 chip containing 45,900 million transistors across a 379 mm² die. It features 16 GB of GDDR6X memory on a 256-bit bus, providing 736.3 GB/s of bandwidth. The base clock is 2,295 MHz with a boost clock of 2,550 MHz, while memory runs at 1,438 MHz (23 Gbps effective). The GPU’s 10,240 shading units, 320 TMUs, and 112 ROPs deliver a texture rate of 816.0 GTexel/s and a pixel rate of 285.6 GPixel/s.

In Rust, these specifications directly influence the measured FPS across settings. The 16 GB VRAM capacity is sufficient for the game’s textures and world assets at 4K Ultra, as evidenced by the 47.5 FPS result at that preset — while not high, it indicates the VRAM is not exhausted. The memory bandwidth of 736.3 GB/s helps maintain stable frame pacing in large open-world environments where the game streams terrain and entities. The FP32 compute of 52.22 TFLOPS handles the game’s lighting and post-processing effects, which scale with settings from Low to Ultra.

The GPU’s benchmark scores show strong performance: Passmark G3D scores 34,245, and 3dmark Steel Nomad DX12 reaches 6,600. The nearest rivals include the AMD Radeon RX 6900 XT (deltaPct 0.2), Radeon Pro W6600M (deltaPct 0.4), Radeon RX 7700S (deltaPct 2.1), and RTX 5070 Ti (deltaPct 2.9). These small deltas indicate the RTX 4080 SUPER is closely matched with these alternatives in synthetic tests, but in Rust, its combination of high bandwidth and substantial shading resources produces the measured 4K performance. The GPU ranks in the 88th percentile among all GPUs, with an average benchmark score of 53,610, confirming its status as a high-end part that pairs well with the 9900X for this title.
