Rust

The AMD Ryzen 7 7700X and AMD Radeon RX 580 pairing in Rust is a study in stark imbalance. Benchmark data shows a modern, high-end processor constrained by a legacy graphics card. The measured results indicate that this combination falls near the bottom of the database, ranking 1594 out of 1717 tested combos. This analysis breaks down the CPU and GPU contributions, resolution scaling, and the exact frame rates observed.

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

The AMD Ryzen 7 7700X is a 7000 series desktop processor built on the Zen 4 architecture, codenamed Raphael, using a 5 nm process from TSMC. It features 8 cores and 16 threads, with a base clock of 4.50 GHz and a boost clock of 5.40 GHz. The CPU's cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB L3 cache. This configuration supports DDR5 memory in a dual-channel layout, providing a memory bandwidth of 83.2 GB/s, and connects via PCIe Gen 5 with 24 lanes.

For a game like Rust, which is known for heavy simulation and world-building logic, the CPU's multi-threaded performance is often critical. The 7700X's benchmark data reflects strong capabilities: it scores 30325 in Cinebench R23 multi-core and 15538 in Geekbench multi-core. Its Passmark multithread score is 35686, placing it in the 89th percentile of all CPUs tested. The single-thread performance is also robust, with a Cinebench R23 single-core score of 4281 and a Passmark single-thread score of 4190. The data suggests this processor has ample headroom to feed even the most demanding graphics card. However, in this pairing, the CPU is not the bottleneck at most settings, as the GPU struggles to keep pace.

The 7700X's nearest rivals in the database include the Intel Core i5-13500, which scores 34175 (a delta of 0.4%), and the Intel Core i7-12800HX at 34136 (a delta of 0.5%). The AMD EPYC 4244P and Intel Core Ultra 7 165H are slightly ahead, with deltas of -0.8% against the 7700X's average score of 34313. These close margins suggest that the 7700X is part of a tightly clustered performance tier, meaning any frame rate differences in Rust at lower resolutions are unlikely to be due to CPU variance among these chips. The data implies that the 7700X's compute power is largely underutilized in this specific configuration.

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

The AMD Radeon RX 580 is a much older component, built on the GCN 4.0 architecture with the Polaris 20 chip, manufactured on a 14 nm process by GlobalFoundries. It has 8 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 256.0 GB/s. The GPU's base clock is 1257 MHz with a boost clock of 1340 MHz, and its memory runs at 2000 MHz (8 Gbps effective). The card features 2304 shading units, 144 texture mapping units, and 32 raster output units. Its compute capabilities are rated at 6.175 TFLOPS for FP32, with a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s.

In the context of Rust, the RX 580's 8 GB of VRAM is sufficient for the game's textures at 1080p, but the raw pixel-pushing power is limited. The GPU's benchmark scores confirm its mid-range status: it sits in the 53rd percentile of all GPUs, with an average benchmark score of 13559. Its nearest rivals are the NVIDIA GeForce GTX 570 (score 13564, delta 0%), the NVIDIA GeForce GTX 950 (score 13549, delta 0.1%), and the AMD Radeon Pro 455 (score 13416, delta 1.1%). The data shows the RX 580 is essentially performance-equivalent to these older cards, indicating its age. The Passmark G3D score of 8813 and DirectX 12 score of 43 highlight that this GPU is a limiting factor for modern titles, particularly at higher resolutions and settings where the fill rate and shading power become insufficient.

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

The measured FPS data reveals a classic pattern of GPU-bound scaling. At 1920x1080 with Low settings, the combo achieves 71.9 FPS, which is the highest recorded average. Moving to 2560x1440 at Low settings, the frame rate drops to 49.4 FPS, a reduction of roughly 31%. At 3840x2160 (4K) with Low settings, the average falls to 28.7 FPS, representing a 60% drop from the 1080p Low result. This steep decline as resolution increases is a clear indicator that the RX 580's rendering throughput is the primary constraint.

The scaling pattern persists across other settings. For High settings, the frame rates are 41.5 FPS at 1080p, 27.1 FPS at 1440p, and 17.3 FPS at 4K. The drop from 1080p to 4K is 58%, which is similar to the Low setting drop. This consistency shows that the GPU's workload scales almost linearly with pixel count, and the CPU is not stepping in to mitigate the losses. If the CPU were the bottleneck, we would expect to see a smaller FPS gap between 1440p and 4K, as the GPU would be overwhelmed. Instead, the data shows the frame rate is closely tied to resolution, confirming the RX 580 is the limiting component across all tested settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations for Rust, this pairing of the Ryzen 7 7700X and Radeon RX 580 ranks 1594 out of 1717 combos. This places it in the bottom 7% of all configurations tested. The ranking is a direct consequence of the GPU's age; the 7700X is a top-tier processor, but the RX 580 holds the entire system back.

The rank suggests that while the CPU is overqualified for the task, the GPU's performance ceiling is low. For context, the CPU alone sits in the 89th percentile of all CPUs, while the GPU sits in the 53rd percentile of all GPUs. This mismatch is not unusual, but the magnitude of the difference is significant. The combo's low rank implies that a user would achieve better overall frame rates by pairing a much weaker CPU with a stronger GPU, as the GPU is the sole determinant of performance in most scenarios. The data indicates that this is not a balanced build for Rust, and the measured FPS numbers corroborate the low ranking.

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

The following are the exact average FPS figures recorded for this hardware combo in Rust, organized by resolution and settings.

At 1920x1080:

• Low: 71.9 FPS
• Medium: 49.7 FPS
• High: 41.5 FPS
• Ultra: 30.8 FPS

At 2560x1440:

• Low: 49.4 FPS
• Medium: 36.2 FPS
• High: 27.1 FPS
• Ultra: 23.3 FPS

At 3840x2160:

• Low: 28.7 FPS
• Medium: 19.9 FPS
• High: 17.3 FPS
• Ultra: 15.5 FPS

The data shows a clear trend: the frame rate halves when moving from 1080p to 4K at the same settings. For example, Medium settings yield 49.7 FPS at 1080p and 19.9 FPS at 4K, a 60% reduction. The Ultra setting is the most demanding, producing only 30.8 FPS at 1080p and falling to 15.5 FPS at 4K. These numbers indicate that the combo is only playable at 1080p with Low or Medium settings, where it can maintain frame rates above 49 FPS. At 1440p, only the Low setting approaches playability at 49.4 FPS, while all other settings fall below 37 FPS. At 4K, all settings produce frame rates below 29 FPS, making the game effectively unplayable.
