GPU Role

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process by TSMC. It houses 2560 shading units, 160 texture mapping units, and 96 render output units, along with 40 ray tracing cores. The GPU's pixel rate is 236.1 GPixel/s and its texture rate is 393.4 GTexel/s, with FP32 performance rated at 25.18 TFLOPS. These specifications place the RX 7700 at the 58th percentile among all GPUs, with an average benchmark score of 15852.

The memory subsystem is a highlight: 16 GB of GDDR6 on a 256-bit bus yields 624.1 GB/s of bandwidth. For Rust, this is particularly relevant because the game loads large, detailed terrain and building structures that require frequent texture streaming. The 16 GB capacity provides ample headroom for high-resolution textures, though the measured FPS data shows that the GPU's raw compute power is the limiting factor at higher resolutions and settings.

In Rust, the GPU's role becomes more pronounced as settings increase. The data shows that at 1920x1080, the average FPS drops from 173 at Low to 75 at Ultra — a reduction of 98 FPS. At 3840x2160, the same settings swing yields 70 FPS at Low versus 30 FPS at Ultra. This indicates that the RX 7700's shading units and ROPs are heavily taxed by Rust's post-processing effects and geometry at higher presets. The GPU's 3DMark Steel Nomad DX12 score of 2865 and Passmark G3D score of 20974 reflect its mid-range positioning, which aligns with the observed FPS behavior.

The GPU's nearest rivals in synthetic benchmarks include the AMD Radeon R9 370X (average score 15862, delta -0.1%), the AMD Radeon RX 9060 (16014, delta -1%), the AMD Radeon Pro W5500 (15679, delta 1.1%), and the NVIDIA GeForce RTX 3060 Ti (16129, delta -1.7%). The RX 7700 sits within 1.7% of these cards, suggesting that Rust performance at similar settings would be closely matched, though the 16 GB VRAM gives it a capacity advantage over older cards with smaller memory pools.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Core 14th Gen series, based on the Raptor Lake architecture (specifically Raptor Lake-R). It operates at a base clock of 2.50 GHz and boosts to 4.70 GHz, with a 65 W TDP. The CPU has a 20 MB shared L3 cache, with 1.25 MB L2 per core and 80 KB L1 per core. It supports DDR4 and DDR5 memory in a dual-channel configuration, and includes ECC memory support. The processor is built on Intel's 10 nm process with a 215 mm² die size.

In Rust, the CPU plays a critical role because the game simulates a persistent world with many entities, including players, animals, and environmental changes. The 10 cores and 16 threads provide substantial parallel processing capability, which is reflected in synthetic benchmarks: Cinebench R23 multicore score of 21645, Cinebench R20 multicore of 9090, and Geekbench multicore of 11268. The single-core performance is also strong, with Cinebench R23 single-core at 3055 and Passmark single-thread at 3701. Rust's game logic often relies on single-threaded performance for physics and network handling, so the 4.70 GHz boost clock is beneficial.

The CPU's average benchmark score is 32279, placing it at the 83rd percentile among all CPUs. Its nearest rivals include the AMD Ryzen 7 PRO 8840U (32233, delta 0.1%), Intel Core i9-11900 (32226, delta 0.2%), AMD Ryzen 7 6800HS (32354, delta -0.2%), and Intel Core i7-12800H (32121, delta 0.5%). These margins are within 0.5%, indicating that the i5-14400F offers competitive processing power for its class.

The measured FPS data suggests that the CPU is not the primary bottleneck in most scenarios. At 1080p Low settings, the combo achieves 173 FPS, which is high enough to suggest that the CPU can feed the GPU effectively. However, at 1080p Ultra, the FPS drops to 75, which is a larger proportional decline than what pure CPU limitations would cause. This points to the GPU becoming the constraint at higher settings, even at lower resolutions, due to Rust's rendering demands.

How This Combo Ranks

The Intel Core i5-14400F paired with the AMD Radeon RX 7700 ranks 1295 out of 2953 tested combos in Rust. This percentile position (~56th) indicates that the combo performs better than the median but sits below the top-performing configurations. The ranking reflects a balance between the CPU's strong multi-threaded capabilities (83rd percentile) and the GPU's more modest positioning (58th percentile).

The data shows that the combo's overall ranking is closer to the GPU's percentile than the CPU's, which suggests that graphics performance is the limiting factor in Rust. The CPU's high synthetic scores do not translate into top-tier FPS because the RX 7700 cannot always keep pace with the processor's output. This is evident in the FPS scaling: at 1440p Low, the combo hits 119 FPS, but at 1440p Ultra it drops to 51 FPS, a 57% reduction that aligns with GPU-bound behavior.

Compared to other combos in the database, the 1295th rank out of 2953 places it in the upper half, but not in the top quartile. This is consistent with the GPU's 58th percentile ranking. For Rust specifically, where both CPU and GPU matter, the combo strikes a middle ground: it can handle large servers and complex bases without the CPU bottlenecking, but the GPU limits maximum visual fidelity and frame rates at high settings.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra). A total of 12 data points were recorded, with some rows including minimum and maximum FPS values.

At 1920x1080, the combo delivers the following average FPS:

• Low: 173 FPS
• Medium: 116 FPS (min 99, max 133)
• High: 98 FPS
• Ultra: 75 FPS

At 2560x1440, the average FPS drops:

• Low: 119 FPS
• Medium: 80 FPS (min 68, max 92)
• High: 67 FPS
• Ultra: 51 FPS

At 3840x2160, the average FPS is significantly lower:

• Low: 70 FPS
• Medium: 47 FPS (min 40, max 54)
• High: 40 FPS
• Ultra: 30 FPS

The data shows a consistent pattern: at each resolution, Low settings provide the highest FPS, followed by Medium, High, and Ultra in descending order. The gap between Low and Ultra widens as resolution increases. At 1080p, the difference is 98 FPS (173 vs 75), at 1440p it is 68 FPS (119 vs 51), and at 4K it is 40 FPS (70 vs 30). This indicates that the GPU's rendering workload scales non-linearly with both resolution and settings.

The Medium preset rows include min and max FPS values, which provide insight into frame time consistency. At 1080p Medium, the minimum is 99 FPS and the maximum is 133 FPS, a spread of 34 FPS. At 1440p Medium, the range is 68 to 92 FPS (24 FPS spread), and at 4K Medium, it is 40 to 54 FPS (14 FPS spread). The tighter range at higher resolutions suggests that the GPU is more consistently saturated, reducing frame time spikes.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate.

For 1920x1080, all presets are playable. Low settings at 173 FPS are ideal for competitive play or high-refresh-rate monitors (144 Hz or higher). Medium settings at 116 FPS provide a good balance between visual quality and smoothness, with a minimum of 99 FPS ensuring minimal stutter. High settings at 98 FPS are still smooth for 60 Hz displays. Ultra settings at 75 FPS are playable but may feel less responsive on high-refresh displays.

For 2560x1440, the choices are more constrained. Low settings at 119 FPS are excellent for high-refresh monitors. Medium settings at 80 FPS are solid for 60-75 Hz displays, with a minimum of 68 FPS keeping above the 60 FPS threshold. High settings at 67 FPS are borderline; they work for 60 Hz but may dip below in busy scenes. Ultra settings at 51 FPS are not recommended for smooth gameplay, as they fall below the 60 FPS target.

For 3840x2160, only Low settings (70 FPS) provide a consistently smooth experience. Medium settings at 47 FPS are playable on 60 Hz displays but may feel sluggish, with a minimum of 40 FPS indicating occasional drops. High settings at 40 FPS and Ultra at 30 FPS are suitable only for slower-paced play or screenshots, not for competitive or action-oriented gameplay.

The data suggests that Medium settings are the sweet spot for most users, offering a reasonable compromise: at 1080p it delivers 116 FPS, at 1440p it delivers 80 FPS, and at 4K it delivers 47 FPS. For users prioritizing frame rate, Low settings are clearly superior, while High and Ultra are best reserved for lower resolutions.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals important characteristics of this combo's bottleneck behavior.

At Low settings, the average FPS drops from 173 at 1080p to 119 at 1440p (a 31% reduction) and then to 70 at 4K (a 41% reduction from 1440p). The total drop from 1080p to 4K is 103 FPS, or a 60% reduction. This is a large decline, but the absolute FPS at 4K Low (70) is still playable, indicating that the GPU can handle lower graphical loads at high pixel counts.

At Medium settings, the FPS goes from 116 at 1080p to 80 at 1440p (31% reduction) and then to 47 at 4K (41% reduction from 1440p). The pattern is similar, with a total reduction of 69 FPS (59%) from 1080p to 4K.

At High settings, the FPS drops from 98 at 1080p to 67 at 1440p (32% reduction) and then to 40 at 4K (40% reduction from 1440p). The total reduction is 58 FPS (59%).

At Ultra settings, the FPS goes from 75 at 1080p to 51 at 1440p (32% reduction) and then to 30 at 4K (41% reduction from 1440p). The total reduction is 45 FPS (60%).

The consistency of these percentage reductions (59-60% total, 31-32% for 1080p to 1440p, and 40-41% for 1440p to 4K) across all settings presets indicates that the scaling is resolution-driven rather than settings-driven. This is a classic sign of a GPU-bound scenario: as the number of pixels increases, the GPU's workload grows proportionally, and the CPU's frame production rate remains constant.

The data suggests that the RX 7700 is the limiting component at all resolutions above 1080p Low. At 1080p Low, the 173 FPS is likely near the CPU's maximum frame rate for Rust, as the GPU is not heavily taxed. Beyond that, the GPU's rendering capacity dictates the FPS. This is corroborated by the 4K results, where even Low settings (70 FPS) show a significant drop from 1080p, indicating the GPU is saturated. The i5-14400F's strong single-thread performance (4.70 GHz boost) is sufficient to feed the GPU at these frame rates, but it cannot overcome the GPU's inherent limits at higher resolutions.
