# Rust Performance Analysis: AMD Ryzen 5 5500X3D + AMD Radeon RX 6700 XT

The measured frame rates for this AMD Ryzen 5 5500X3D and AMD Radeon RX 6700 XT combination in Rust reveal a system that scales predictably across resolutions and settings, with the data showing a clear transition from CPU-bound behavior at 1080p to GPU-bound behavior at 4K. The combo ranks 1484th out of 2953 tested combinations, placing it in the 50th percentile of all tested systems for this game. The Ryzen 5 5500X3D, a 6-core/12-thread Zen 3 part with a 3.00 GHz base and 4.00 GHz boost clock, pairs with a 12 GB Radeon RX 6700 XT (Navi 22, RDNA 2.0) to deliver playable frame rates across most configurations, though the data shows significant drops at higher resolutions and Ultra settings.

Resolution Scaling

The FPS progression from 1920x1080 to 3840x2160 demonstrates how the bottleneck shifts as pixel count increases. At Low settings, the average frame rate drops from 165 FPS at 1080p to 114 FPS at 1440p, then to 67 FPS at 4K — a decline of 51 FPS (31%) from 1080p to 1440p, and another 47 FPS (41%) from 1440p to 4K. This steep falloff at 4K Low indicates the GPU becomes the primary limiting factor once the resolution quadruples the pixel workload, as the RX 6700 XT's 384.0 GB/s memory bandwidth and 13.21 TFLOPS FP32 throughput are taxed heavily.

At Medium settings, the scaling pattern is similar but compressed: 111 FPS at 1080p, 76 FPS at 1440p, and 45 FPS at 4K. The percentage drops are 31.5% from 1080p to 1440p, and 40.8% from 1440p to 4K, nearly identical to the Low-setting deltas. This consistency suggests the GPU workload scaling is uniform across these two presets, with the CPU overhead from Medium settings not yet becoming a limiting factor.

High settings show a slightly shallower curve: 93 FPS at 1080p, 64 FPS at 1440p, and 38 FPS at 4K. The drop from 1080p to 1440p is 31.2%, but the drop from 1440p to 4K is 40.6% — again, the largest absolute loss occurs at the 4K step. The 55 FPS difference between 1080p High and 4K High represents a 59% reduction in average frame rate, which is substantial but not unexpected for a game like Rust with its large draw distances and complex scene rendering.

Ultra settings produce the most dramatic scaling: 71 FPS at 1080p, 49 FPS at 1440p, and 29 FPS at 4K. The 1080p-to-1440p drop is 31%, while the 1440p-to-4K drop is 40.8%. Notably, the 4K Ultra result of 29 FPS falls below the 30 FPS threshold commonly considered minimum for playability, indicating this combo cannot handle maximum settings at 4K. The consistent ~31% and ~41% drops across all four presets strongly suggest the RX 6700 XT's rendering pipeline is the bottleneck at higher resolutions, while at 1080p the CPU's 6 cores and 12 threads may be holding back performance, particularly at Low settings where the GPU has less work to do.

How This Combo Ranks

The Ryzen 5 5500X3D + RX 6700 XT combination ranks 1484th out of 2953 tested combos in Rust, placing it almost exactly at the median of all tested systems. This mid-pack positioning reflects a balanced pairing where neither component dramatically overperforms nor underperforms relative to the other. The CPU's percentile versus all CPUs is 85, meaning it outperforms 85% of all processors in the database, while the GPU's percentile versus all GPUs is 72. The combination of a top-quartile CPU with a top-quartile GPU results in a roughly 50th-percentile gaming combo, which suggests that Rust's performance is not purely dictated by either component alone but rather by their interaction at various settings.

The rank of 1484 out of 2953 means this combo sits above 1469 other tested combinations and below 1483 others. This median placement is consistent with the measured FPS data showing playable but not exceptional performance — the combo can hit 165 FPS at 1080p Low, but drops to 29 FPS at 4K Ultra. The data indicates that for competitive play at lower resolutions and settings, this combo ranks respectably, but for maximum visual fidelity at high resolutions, it falls behind many other tested systems.

When compared to other combos in the database, the 5500X3D's PassMark multithread score of 20,363 and single-thread score of 2,941 suggest solid CPU headroom, while the RX 6700 XT's PassMark G3D score of 19,786 indicates mid-range GPU capability. The combo's median rank reflects that in Rust, which is known for its CPU-intensive simulation and physics, the 6-core CPU is adequate but not exceptional, and the GPU's 12 GB VRAM and 192-bit memory bus provide sufficient but not overwhelming bandwidth for 4K workloads.

CPU Role

The AMD Ryzen 5 5500X3D is a 6-core, 12-thread processor based on Zen 3 architecture (Vermeer codename) built on TSMC's 7 nm process. Its base clock of 3.00 GHz and boost clock of 4.00 GHz are modest for a 2025 release, but the 96 MB shared L3 cache is the standout feature, providing a large cache pool that benefits games with repetitive data access patterns like Rust. The CPU's 105 W TDP and 74 mm² die size indicate a power-efficient design that doesn't require exotic cooling.

Benchmark data shows the 5500X3D scoring 20,363 in PassMark multithread and 2,941 in single-thread tests. Its nearest rival, the AMD Ryzen 5 5600F, scores 36,945 on average (0.2% higher), while the Intel Core Ultra 5 225 scores 36,938 (0.2% lower). This places the 5500X3D within a tight performance band around its rivals, with all four nearest competitors within 0.3% of its average score of 37,018. The CPU's 85th percentile ranking among all CPUs confirms it is a strong performer, though not a top-tier part.

In Rust, the CPU's role is critical for simulation, entity processing, and server-side logic, especially at lower resolutions where the GPU has spare capacity. The data shows that at 1080p Low, the combo achieves 165 FPS, which is the highest measured result across all configurations — this suggests the CPU is capable of driving high frame rates when the GPU isn't bottlenecked. However, at 4K Low, the frame rate drops to 67 FPS, indicating that the GPU becomes the limiting factor at higher pixel counts. The L3 cache's 96 MB size is particularly relevant for Rust, which frequently accesses world data and entity positions; the large cache likely helps maintain consistent frame times in complex scenes.

The CPU's dual-channel DDR4 memory support with 51.2 GB/s bandwidth is adequate for this pairing, though not exceptional. The 12 threads allow for background tasks and OS overhead without starving the game's main threads. The PassMark physics score of 2,282 and find prime numbers score of 170 indicate solid computational throughput, which translates to smooth gameplay in physics-heavy scenarios common in survival games.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 165 FPS average, which is well above the 144 Hz refresh rate common in gaming monitors. Medium settings drop to 111 FPS with a minimum of 94 FPS and maximum of 127 FPS, providing a comfortable margin above 60 FPS. High settings yield 93 FPS, still smooth for most displays. Ultra settings reduce performance to 71 FPS, which remains playable but shows the cost of maximum visual fidelity. The spread from 165 FPS at Low to 71 FPS at Ultra represents a 57% reduction in average frame rate at 1080p.

Moving to 2560x1440, the performance drops are consistent across settings. Low settings average 114 FPS, a 30.9% reduction from 1080p. Medium settings average 76 FPS with a minimum of 65 FPS and maximum of 88 FPS, keeping above the 60 FPS threshold. High settings average 64 FPS, which is close to but above 60 FPS. Ultra settings average 49 FPS, which is below the 60 FPS target but still usable for slower-paced survival gameplay. The 1440p results show that Medium settings offer the best balance of visual quality and frame rate, with the 76 FPS average providing headroom for dips.

At 3840x2160, the combo struggles to maintain playable frame rates at higher settings. Low settings average 67 FPS, which is playable. Medium settings average 45 FPS with a minimum of 38 FPS and maximum of 52 FPS, showing significant frame time variance. High settings average 38 FPS, which is borderline for smooth gameplay. Ultra settings average 29 FPS, which falls below the 30 FPS threshold and may result in noticeable stuttering. The 4K data reveals that only Low settings provide a consistently smooth experience, while Medium is marginal and High/Ultra are not recommended for this resolution.

The measured data includes minimum and maximum FPS only for Medium settings across all three resolutions. At 1080p Medium, the range is 94-127 FPS; at 1440p Medium, 65-88 FPS; at 4K Medium, 38-52 FPS. These ranges show that frame pacing is relatively stable, with the variance being proportional to the average FPS at each resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, Ultra settings provide 71 FPS, which is above the 60 FPS threshold, making it the best choice for visual quality without sacrificing smoothness. However, for competitive play or high refresh rate displays, Low settings at 165 FPS or Medium at 111 FPS offer significantly higher frame rates with reduced visual fidelity. The 94 FPS minimum at Medium settings ensures consistent performance even during intense scenes.

At 2560x1440, Medium settings deliver 76 FPS average with a 65 FPS minimum, making this the recommended preset for 1440p gaming. High settings at 64 FPS are close to the 60 FPS target but leave less headroom for frame drops, while Ultra at 49 FPS falls below the smoothness threshold. Low settings at 114 FPS are viable for players prioritizing frame rate over visuals, but Medium offers the best balance.

At 3840x2160, only Low settings at 67 FPS are recommended for a consistently smooth experience. Medium at 45 FPS is playable but may show stuttering during busy scenes, given the 38 FPS minimum. High at 38 FPS and Ultra at 29 FPS are not recommended for 4K, as they fall below acceptable playability thresholds. Players wanting 4K at higher settings would need a more powerful GPU than the RX 6700 XT.

The data shows a clear pattern: Medium settings provide the best frame rate-to-visual quality trade-off at 1080p and 1440p, while Low is the only viable option at 4K. The 5500X3D's 96 MB L3 cache and 6 cores are sufficient for Medium settings at all resolutions, but Ultra settings at 4K exceed the GPU's capabilities.

GPU Role

The AMD Radeon RX 6700 XT is built on the Navi 22 chip with RDNA 2.0 architecture, featuring 2,560 shading units, 160 texture mapping units, and 64 raster output units. Its 12 GB of GDDR6 memory on a 192-bit bus delivers 384.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p gaming but becomes a limiting factor at 4K. The GPU's boost clock of 2,581 MHz and game clock of 2,424 MHz are high for the RDNA 2 generation, contributing to its 13.21 TFLOPS FP32 compute performance.

The GPU's PassMark G3D score of 19,786 places it in the 72nd percentile of all GPUs, with an average benchmark score of 27,425. Its nearest rival, the NVIDIA GeForce RTX 4070 Mobile, scores 27,435 (0% delta), while the RTX 3090 scores 27,565 (0.5% higher). This places the RX 6700 XT in a competitive position against higher-tier NVIDIA parts, though its 12 GB VRAM and 192-bit memory bus are modest by current standards.

In Rust, the GPU's role becomes dominant at higher resolutions and settings. At 4K, the pixel workload quadruples from 1080p, and the data shows the frame rate drops by approximately 59-60% across all settings when moving from 1080p to 4K. This indicates the GPU's rendering throughput is the primary bottleneck at 4K, as the CPU's performance headroom (evidenced by 165 FPS at 1080p Low) cannot compensate for the GPU's limitations at higher pixel counts.

The GPU's 40 ray tracing cores are present but unused in Rust, as the game does not appear to leverage RT features based on the measured data. The 64 ROPs provide adequate pixel fill rate (165.2 GPixel/s) for 1080p and 1440p, but the 4K results show that the 13.21 TFLOPS FP32 throughput is insufficient for Ultra settings at that resolution. The 230 W TDP and dual-slot design indicate a power-hungry card, but the 550 W suggested PSU is reasonable for most systems.

The GPU's 12 GB VRAM is adequate for Rust at all tested settings, as the game's textures and world data likely fit within this allocation. The 384.0 GB/s memory bandwidth, however, appears to be a limiting factor at 4K, where the frame rate drops more steeply than would be expected from compute performance alone. The memory clock of 2,000 MHz (16 Gbps effective) is standard for GDDR6, and the 192-bit bus width constrains bandwidth compared to 256-bit or wider implementations.
