Rust

The AMD Ryzen 7 9700F and AMD Radeon RX 7700 combination delivers a mid-pack experience in Rust, landing at rank 1295 out of 2953 tested combos. This pairing of AMD's Zen 5 desktop processor with the RDNA 3.0 graphics card produces a playable but not exceptional frame rate profile across resolutions, with the data showing a clear shift in bottleneck behavior as pixel count rises.

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

The AMD Ryzen 7 9700F is an 8-core, 16-thread processor based on the Zen 5 architecture, built on TSMC's 4 nm process. It operates with a base clock of 3.80 GHz and a boost clock of 5.50 GHz, drawing a 65 W TDP. Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The processor supports DDR5 memory over a dual-channel bus with a bandwidth of 89.6 GB/s, and it connects to the platform via PCIe Gen 5 with 24 lanes available from the CPU.

In synthetic benchmark terms, the 9700F posts a Passmark multithread score of 36470 and a single-thread score of 4691. Its average benchmark score of 69996 places it in the 94th percentile of all CPUs tested. The nearest rivals in aggregate score are the Intel Core i7-14700KF at 70163 (0.2% ahead), the AMD Ryzen 9 7940HX at 69875 (0.2% behind), the AMD Ryzen 9 7950X at 69515 (0.7% behind), and the Intel Core i7-14700K at 69355 (0.9% behind). This tight grouping indicates the 9700F is a strong general-purpose performer, though not a standout leader.

For Rust specifically, the CPU's contribution is most evident at lower resolutions where frame rates are high. At 1080p Low, the combo reaches 173 avg FPS, which is significantly higher than at 4K Low at 70 avg FPS. The 5.50 GHz boost clock and 16 threads provide ample headroom for Rust's simulation and entity-tracking workloads, but the data suggests that at 1080p the processor is not the primary limiter. The single-thread score of 4691 and the Passmark physics score of 2122 indicate solid per-core performance, which matters for a game like Rust that relies heavily on a single main thread for world updates. The 32 MB of shared L3 cache helps with the game's frequent memory accesses to world state and player inventories.

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

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on TSMC's 5 nm process. It packs 16 GB of GDDR6 memory on a 256-bit bus, delivering a bandwidth of 624.1 GB/s. The GPU has 2560 shading units, 160 texture mapping units, and 96 raster operation pipelines, along with 40 ray tracing cores. Its base clock is 1900 MHz, with a game clock of 2041 MHz and a boost clock of 2459 MHz. The memory runs at 2438 MHz, translating to 19.5 Gbps effective throughput. The card's FP32 compute is rated at 25.18 TFLOPS, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

In Passmark G3D testing, the RX 7700 scores 20974, with a GPU compute score of 10963. Its average benchmark score is 15852, placing it in the 58th percentile of all GPUs. The nearest rivals are the AMD Radeon R9 370X at 15862 (0.1% ahead), the AMD Radeon RX 9060 at 16014 (1% ahead), the AMD Radeon Pro W5500 at 15679 (1.1% behind), and the NVIDIA GeForce RTX 3060 Ti at 16129 (1.7% ahead). This puts the RX 7700 in a competitive mid-range tier, though its percentile rank suggests it is not a top-tier part.

The GPU's role in Rust becomes dominant as resolution and settings increase. At 4K Ultra, the combo falls to 30 avg FPS, a clear indication that the RX 7700 is struggling to fill the 16 GB framebuffer with the game's heavy draw calls and texture streaming. The 16 GB VRAM is sufficient for Rust's large maps and high-resolution textures, as evidenced by the fact that even at 4K High the combo manages 40 avg FPS, but the compute throughput of 25.18 TFLOPS is not enough to maintain high frame rates at 4K. The 624.1 GB/s bandwidth helps with texture streaming, but the data shows that the GPU is the limiting factor at 1440p and above, particularly at Ultra settings.

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 across resolutions. Starting at 1080p Low, the combo delivers 173 avg FPS. Moving to 1440p Low, that drops to 119 avg FPS, a reduction of 54 FPS or approximately 31%. At 4K Low, the average falls to 70 FPS, which is another 49 FPS drop from 1440p, or about 41%. This steep decline at Low settings suggests that even with minimal graphical load, the GPU is becoming the bottleneck as pixel count quadruples from 1080p to 4K.

At Medium settings, the pattern is similar. 1080p Medium yields 116 avg FPS, 1440p Medium yields 80 avg FPS, and 4K Medium yields 47 avg FPS. The drop from 1080p to 1440p is 36 FPS, and from 1440p to 4K is 33 FPS. The 4K Medium result includes a min FPS of 40 and a max of 54, showing some frame pacing variability. At High settings, 1080p produces 98 avg FPS, 1440p produces 67 avg FPS, and 4K produces 40 avg FPS. The drops are 31 FPS and 27 FPS respectively, indicating a slightly more gradual decline than at Low settings.

Ultra settings show the most dramatic scaling. 1080p Ultra yields 75 avg FPS, 1440p Ultra yields 51 avg FPS, and 4K Ultra yields 30 avg FPS. The drop from 1080p to 1440p is 24 FPS, and from 1440p to 4K is 21 FPS. At 4K Ultra, the 30 avg FPS is at the edge of playability, and the data suggests the GPU is heavily saturated. The fact that the FPS drops are relatively consistent in absolute terms across settings, but proportionally larger at Low settings, indicates that the CPU is keeping up at 1080p but the GPU's workload scales predictably with resolution. At 1080p Low, the 173 FPS result suggests the CPU has headroom, but at 4K Ultra, the 30 FPS result shows the GPU is the clear limiter. The transition point appears to be around 1440p, where the combo starts to become GPU-bound.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 7 9700F and AMD Radeon RX 7700 combination ranks 1295 out of 2953 tested combos in Rust. This places it in the 44th percentile of all tested pairings, meaning roughly 56% of combos tested perform better in this game. The rank reflects a mid-pack position, consistent with the GPU's 58th percentile standing and the CPU's higher 94th percentile. The data suggests that the GPU is the limiting factor in this pairing, as the CPU's strong benchmark scores are not fully utilized at higher resolutions.

The combo's position relative to its components' individual standings indicates a slight underperformance. The CPU ranks in the 94th percentile, but the combo only reaches the 44th percentile, suggesting that the RX 7700 holds the pairing back. The nearest rival GPUs, such as the NVIDIA GeForce RTX 3060 Ti, which is only 1.7% ahead in average score, might produce similar or slightly better results in Rust, but the data for this specific game does not include direct comparisons with those cards. The rank of 1295 out of 2953 is a solid mid-table result, but it is not a top performer for Rust's demanding rendering and simulation workloads.

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

The measured FPS data for Rust with the AMD Ryzen 7 9700F and AMD Radeon RX 7700 is as follows.

At 1920x1080, Low settings produce an average of 173 FPS. Medium settings average 116 FPS, with a minimum of 99 and a maximum of 133. High settings average 98 FPS. Ultra settings average 75 FPS.

At 2560x1440, Low settings average 119 FPS. Medium settings average 80 FPS, with a minimum of 68 and a maximum of 92. High settings average 67 FPS. Ultra settings average 51 FPS.

At 3840x2160, Low settings average 70 FPS. Medium settings average 47 FPS, with a minimum of 40 and a maximum of 54. High settings average 40 FPS. Ultra settings average 30 FPS.

The data shows a monotonic decrease in average FPS as both resolution and settings increase. The largest jump in performance is from 4K Ultra at 30 FPS to 1080p Low at 173 FPS, a 143 FPS difference. The Medium settings at each resolution provide the most complete data with min and max values, showing that frame times are relatively stable with a spread of about 14 to 34 FPS. The 1080p Medium spread is 34 FPS (99 to 133), while the 1440p Medium spread is 24 FPS (68 to 92), and the 4K Medium spread is 14 FPS (40 to 54). This tightening of the frame range at higher resolutions further confirms that the GPU is the primary limiter, as it smooths out frame delivery under heavier load.
