Rust

Resolution Scaling

Rust shows a steep and predictable performance curve as resolution climbs, and the data makes the bottleneck story clear. At 1920x1080 with Low settings, the AMD Ryzen 5 7500F and AMD Radeon RX 7700 combo delivers 173 FPS average. Moving to 2560x1440 Low drops that to 119 FPS, a 31% reduction. At 3840x2160 Low, the average falls to 70 FPS, which is another 41% cut from the 1440p result. That scaling pattern — roughly one-third lost at each step up — points to the GPU becoming the primary limiter as pixel count grows, because the CPU workload in Rust at Low settings is largely unchanged by resolution.

The High preset tells a similar but less dramatic story. At 1080p High, the combo averages 98 FPS. At 1440p High, that falls to 67 FPS (a 32% drop), and at 4K High it reaches 40 FPS (a 40% drop from 1440p). The percentage losses are consistent across Low and High, which suggests the frame rate ceiling at 1080p is not being hit by the CPU in this title — if it were, the drop from 1080p to 1440p would be smaller, since the GPU would still have headroom to absorb the extra pixels.

What is telling is the gap between Low and Ultra at each resolution. At 1080p, Low runs at 173 FPS while Ultra runs at 75 FPS — a 98 FPS spread. At 1440p, the spread narrows to 68 FPS (119 vs 51). At 4K, it narrows further to 40 FPS (70 vs 30). This compression of the settings range as resolution increases is classic GPU-bound behavior. The RX 7700's rendering throughput is the wall at 4K, and no amount of lowering settings can fully compensate — even at Low, 4K only manages 70 FPS, which is below the 1080p Ultra result of 75 FPS.

The measured FPS data for Medium settings at each resolution includes min and max values, which adds texture. At 1080p Medium, the average is 116 FPS with a min of 99 and max of 133. At 1440p Medium, the average drops to 80 FPS with a min of 68 and max of 92. At 4K Medium, the average is 47 FPS with a min of 40 and max of 54. The min-to-max spread is roughly 30% of the average at each resolution, indicating that Rust's frame pacing is somewhat erratic regardless of resolution — a trait common in survival games with dynamic world loading and player-built structures.

For a practical takeaway: this combo is clearly a 1080p and 1440p setup for Rust. At 1080p, it can push past 170 FPS on Low and stay above 75 FPS on Ultra, making it viable for high-refresh monitors. At 1440p, it remains playable on High (67 FPS) but dips below 60 on Ultra (51 FPS). At 4K, only Low settings clear 60 FPS (70 FPS), and Ultra is a slideshow at 30 FPS. The scaling data suggests that if you target 4K, you will be fighting the GPU every step of the way; if you target high refresh at 1080p, the CPU has enough headroom to keep up.

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 at TSMC. It carries 16 GB of GDDR6 memory on a 256-bit bus, yielding 624.1 GB/s of memory bandwidth. The memory clock runs at 2438 MHz, which translates to 19.5 Gbps effective. These specifications matter for Rust because the game is known for large, persistent worlds with heavy texture streaming and frequent asset loading — the 16 GB frame buffer is a meaningful asset, though the measured FPS data suggests that memory capacity is not the limiting factor at 4K Ultra (30 FPS), since even Low settings at 4K only reach 70 FPS.

The GPU's clock behavior is worth noting. The base clock is 1900 MHz, the game clock is 2041 MHz, and the boost clock is 2459 MHz. The spread between base and boost is 559 MHz, which gives the card headroom to ramp up under load. In Rust, where scenes can alternate between sparse outdoor areas and dense player-built compounds, the boost algorithm likely helps maintain frame rate during sudden geometry spikes. The 2560 shading units, 160 texture mapping units, and 96 render output units provide the raw throughput — 25.18 TFLOPS FP32 and a texture rate of 393.4 GTexel/s — that drives the 1080p and 1440p results.

Comparing to its nearest rivals in the database, the RX 7700's average benchmark score is 15852. That places it just 0.1% behind the AMD Radeon R9 370X (15862), 1% behind the AMD Radeon RX 9060 (16014), 1.1% ahead of the AMD Radeon Pro W5500 (15679), and 1.7% behind the NVIDIA GeForce RTX 3060 Ti (16129). These are tight margins — the RX 7700 sits in a crowded performance band where a few percent separates it from older and similarly positioned cards. In Rust specifically, the measured FPS shows this card is capable of 116 FPS at 1080p Medium and 80 FPS at 1440p Medium, which aligns with its 58th percentile ranking among all GPUs.

The GPU's RDNA 3.0 architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Rust's rendering engine can leverage these APIs, though the game's CPU-heavy simulation often means the GPU is waiting on draw calls rather than the reverse. At 1080p Low, the 173 FPS result suggests the GPU is not the bottleneck — the CPU is likely feeding it frames as fast as it can. At 4K Ultra, the 30 FPS result shows the GPU's rasterization limits are being hit hard. The 96 ROPs and 236.1 GPixel/s pixel rate are the figures that matter for 4K fill-rate demands, and they are clearly insufficient for Ultra settings at that resolution.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor from the 7000 series, built on Zen 4 architecture (codenamed Raphael) using a 5 nm TSMC process. It runs at a 3.70 GHz base clock and boosts to 5.00 GHz. The 65 W TDP and unlocked multiplier make it a flexible choice for builders who want to tune performance. It supports DDR5 memory in dual-channel configuration, with a memory bandwidth of 83.2 GB/s, and connects via PCIe Gen 5 with 24 lanes from the CPU.

In Rust, the CPU's role is substantial. The game's simulation — including entity updates, physics, and server-side logic that affects client rendering — is heavily single-thread dependent. The 7500F's single-thread performance is strong: it scores 974 in 3DMark single-thread, 324 in Cinebench R15 single-core, 1351 in Cinebench R20 single-core, and 3218 in Cinebench R23 single-core. These scores indicate a per-core performance level that can keep up with the GPU at 1080p, where the combo reaches 173 FPS on Low. The measured data supports this: if the CPU were weak in single-thread, the 1080p Low result would be much lower than 173 FPS, since the GPU would be idle waiting for CPU instructions.

Multi-thread performance is also relevant for Rust's background tasks, such as asset decompression and world generation. The 7500F scores 6376 in 3DMark 16-thread and 6379 in 3DMark max-thread, with Cinebench R23 multi-core at 22799. The PassMark multithread score is 26825, and the average benchmark score across all tests is 24964. This places the CPU in the 77th percentile among all CPUs, with nearest rivals being the Intel Core i7-11850H (24935, 0.1% ahead), AMD Ryzen 5 8400F (25005, 0.2% behind), Intel Core i7-13620H (24911, 0.1% ahead), and Intel Core 5 210H (24872, 0.4% ahead). These are all within 0.4% of each other, meaning the 7500F is firmly in a mid-pack grouping for overall CPU compute.

For Rust specifically, the 12 threads (6 cores with SMT) provide enough parallelism for the game's background systems while the boost clock of 5.00 GHz handles the primary game thread. The L3 cache is 32 MB shared, which helps with the game's large working set of entities and world data. The L1 cache is 64 KB per core and L2 is 1 MB per core, providing fast access to frequently used data. The CPU's 3DMark 2-thread score of 1902 is particularly relevant, since Rust's main thread often works alongside a second thread for rendering — a strong 2-thread score means the game's core loop has enough headroom.

The data shows no frame rate collapse at 1080p when settings are lowered — 173 FPS on Low versus 98 FPS on High. This indicates the CPU can feed the GPU at high rates, but the GPU becomes the limiter as settings increase. At 4K, the CPU is almost certainly not the bottleneck, since even at Low the GPU only produces 70 FPS. The 7500F's role in this combo is to provide a stable foundation that does not hold back the RX 7700 until very high frame rates, which is exactly what the measured FPS pattern shows.

How This Combo Ranks

This specific combination of AMD Ryzen 5 7500F and AMD Radeon RX 7700 ranks 1295 out of 2953 tested combos in the database for Rust. That places it in the 44th percentile of all combos tested — slightly below the middle of the pack. The rank reflects the pairing's overall performance in this game, not just the GPU or CPU individually. Given that the CPU sits in the 77th percentile and the GPU in the 58th percentile, the combo rank of 1295 suggests that Rust's performance characteristics — likely its CPU sensitivity at lower resolutions and GPU sensitivity at higher resolutions — average out to a mid-tier result.

The rank is informative when compared to the component-level percentiles. The CPU is strong relative to all CPUs, and the GPU is above average relative to all GPUs, but the combo as a whole does not crack the top half of all pairings. This implies that many other combos in the database have either a stronger GPU, a stronger CPU, or a better balance for Rust's specific workload. The 1295 rank means that out of 2953 combos, 1658 outperform it. That is a large number, but it also means 1295 combos are worse, so this pairing is not at the bottom — it is a solid mid-rung option.

What the rank does not tell you directly is why the combo lands there. The measured FPS data provides the answer: at 1080p, the combo is strong (173 FPS on Low), but at 4K Ultra it is weak (30 FPS). Many combos in the database likely feature higher-end GPUs that push 4K performance higher, or higher-end CPUs that push 1080p Low beyond 173 FPS. The combo's rank is a weighted average across all settings and resolutions tested, and the 4K results drag it down significantly. If Rust were only tested at 1080p, this combo would rank much higher.

The data also shows that the combo's performance is consistent with its component-level scores. The RX 7700's nearest rival, the RTX 3060 Ti, is 1.7% ahead in average GPU score. The 7500F's nearest rival, the Ryzen 5 8400F, is 0.2% ahead in CPU score. These small deltas mean the combo's rank is not an outlier — it performs as expected given the parts. The 1295 rank is a fair representation of a mid-pack pairing that excels at 1080p, handles 1440p reasonably, and struggles at 4K Ultra.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings levels (Low, Medium, High, Ultra). Medium is the only setting with full min/max/avg data at every resolution, so it provides the most complete picture of frame pacing.

At 1920x1080: Low averages 173 FPS. Medium averages 116 FPS, with a min of 99 and max of 133. High averages 98 FPS. Ultra averages 75 FPS. The spread from Low to Ultra is 98 FPS. The Medium min of 99 FPS indicates the combo can hold near triple-digit frame rates even during demanding scenes at 1080p. The max of 133 FPS on Medium shows headroom exists, but the average of 116 FPS is more representative of sustained gameplay.

At 2560x1440: Low averages 119 FPS. Medium averages 80 FPS, with a min of 68 and max of 92. High averages 67 FPS. Ultra averages 51 FPS. The spread from Low to Ultra is 68 FPS. The Medium min of 68 FPS is just below the 70 FPS threshold that many players consider the floor for smooth gameplay, meaning 1440p Medium will occasionally dip into less comfortable territory. The High average of 67 FPS is borderline; Ultra at 51 FPS is playable but not ideal for fast-paced combat.

At 3840x2160: Low averages 70 FPS. Medium averages 47 FPS, with a min of 40 and max of 54. High averages 40 FPS. Ultra averages 30 FPS. The spread from Low to Ultra is 40 FPS. The Medium min of 40 FPS is a significant drop from the 1080p Medium min of 99 FPS. Even at Low, the 4K average of 70 FPS is below the 1440p High average of 67 FPS — the GPU is clearly the limiting factor at this resolution. Ultra at 30 FPS is effectively unplayable for competitive play but might be acceptable for screenshots or slow exploration.

The data reveals that the combo's best experience is at 1080p, where every setting level exceeds 75 FPS. At 1440p, only Low and Medium exceed 60 FPS. At 4K, only Low exceeds 60 FPS. The Medium setting data, with its min/max values, shows that frame drops are more severe at higher resolutions — the 4K Medium min (40 FPS) is 34% below its average (47 FPS), while the 1080p Medium min (99 FPS) is 15% below its average (116 FPS). This indicates that Rust's rendering complexity at 4K creates more pronounced spikes in GPU load.
