Rust

Resolution Scaling

The measured frame rates for Rust with the AMD Ryzen 7 5700 and AMD Radeon RX 7700 XT show a clear and predictable degradation as resolution increases, but the shape of that curve reveals important information about where the bottleneck sits. At 1080p with Low settings, the combination produces 190 FPS on average. Moving to 1440p drops that to 130 FPS, a reduction of 60 FPS or roughly 32%. The jump from 1440p to 4K at Low settings brings the average down to 77 FPS, another 53 FPS loss, or about 41% of the 1440p figure.

The scaling pattern shifts when looking at higher settings. At High settings, 1080p yields 107 FPS, 1440p drops to 74 FPS, and 4K falls to 44 FPS. The percentage losses between successive resolutions are similar in magnitude to the Low setting case, but the absolute FPS values are much lower, indicating that the GPU is becoming the primary constraint as settings increase. The Medium preset tells a similar story: 127 FPS at 1080p, 88 FPS at 1440p, and 52 FPS at 4K. The Ultra preset shows the steepest decline, going from 82 FPS at 1080p to 56 FPS at 1440p and finally 33 FPS at 4K.

What this data suggests is that at Low settings and 1080p, the system is likely CPU-limited or at least balanced, since the 190 FPS figure is high enough that the CPU's per-thread performance becomes relevant. The Ryzen 7 5700's single-thread score in 3DMark is 901, and its Cinebench R23 single-core score is 2916, which are respectable but not class-leading figures. As resolution climbs, the GPU workload grows, and the RX 7700 XT's raw throughput starts to dominate the frame rate equation. The gap between Low and Ultra at 4K is 44 FPS (77 vs 33), while the same gap at 1080p is 108 FPS (190 vs 82). This compression at 4K is the classic signature of GPU-bound rendering.

The 4K Medium row includes a minimum FPS of 44 and a maximum of 59, which brackets the 4K High average of 44 FPS. That overlap indicates that the difference between Medium and High at 4K is not enormous, but the average gap of 8 FPS (52 vs 44) is consistent enough to be meaningful. The frame time consistency, as implied by the min-max range at Medium, suggests that the GPU is working hard but not stuttering catastrophically.

GPU Role

The AMD Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, with memory bandwidth rated at 432.0 GB/s. For a game like Rust, which is known for large, persistent worlds and frequent asset streaming, this memory configuration matters. The GPU's base clock is 1435 MHz, the game clock is listed at 2171 MHz, and the boost clock reaches 2544 MHz. Those clock speeds, combined with 3456 shading units, 216 texture mapping units, and 96 raster operation units, define the card's raw fill rate and compute capacity.

The GPU's performance percentiles place it at the 67th percentile among all GPUs in the database, with an average benchmark score of 22549. Its nearest rivals include the NVIDIA GeForce RTX 5060 Mobile (average score 22435, delta 0.5%), the RTX 4060 Mobile (22729, delta -0.8%), the RTX 2080 (22895, delta -1.5%), and the AMD Radeon RX 5700 (22170, delta 1.7%). These deltas are all within 2% of the RX 7700 XT's score, meaning that in synthetic benchmarks, this card trades blows with those models. In Rust specifically, the measured FPS data shows that the GPU can push 190 FPS at 1080p Low, but drops to 33 FPS at 4K Ultra, a range that highlights the card's capability at mainstream resolutions and its limits at enthusiast 4K settings.

The VRAM allocation of 12 GB is likely sufficient for Rust's needs at 1080p and 1440p, where the frame rates are high. At 4K, the GPU is clearly compute-bound rather than VRAM-limited, given that the low preset at 4K still achieves 77 FPS. The memory clock of 2250 MHz (18 Gbps effective) and the 192-bit bus combine for that 432.0 GB/s figure, which is adequate but not exceptional for a card in this class. The FP32 throughput of 35.17 TFLOPS and the pixel rate of 244.2 GPixel/s provide context for why the card scales as it does across resolutions.

Settings Recommendations

The measured FPS data provides a clear basis for choosing a preset based on target resolution and desired frame rate. At 1080p, every preset achieves a playable frame rate, with Low at 190 FPS, Medium at 127 FPS, High at 107 FPS, and Ultra at 82 FPS. For competitive play or high-refresh monitors, Low is the obvious choice. For a balance of visual quality and smoothness, Medium at 127 FPS is strong, and High at 107 FPS remains above 100 FPS. Ultra at 82 FPS is still comfortable for most displays.

At 1440p, the situation tightens. Low offers 130 FPS, Medium 88 FPS, High 74 FPS, and Ultra 56 FPS. If the target is 60 FPS, Ultra just barely misses it, so High at 74 FPS provides a safer margin while still looking good. Medium at 88 FPS is the best choice for users who want a solid frame rate buffer. Low at 130 FPS is for those who prioritize performance above all else.

At 4K, the recommendations change dramatically. Ultra at 33 FPS is not ideal for most players. High at 44 FPS is borderline. Medium at 52 FPS is the first preset that approaches playable smoothness, and Low at 77 FPS is the only preset that clears 60 FPS comfortably. For 4K users, the data suggests using Low if frame rate matters, or Medium if visual fidelity is worth a 25 FPS sacrifice. There is no preset at 4K that delivers both high visual quality and high frame rates with this hardware.

The Medium preset at 1440p, with an average of 88 FPS and a min-max range of 74 to 101 FPS, appears to be the sweet spot for this combination. It offers a substantial improvement over Low in visual terms, while staying well above the 60 FPS threshold and providing a frame time range that indicates stable performance. At 1080p, Medium's 127 FPS average with a min of 108 FPS is similarly well-balanced.

Measured FPS Breakdown

The full dataset of measured frame rates covers three resolutions and four settings presets. At 1920x1080, the Low preset averages 190 FPS. Medium averages 127 FPS, with a recorded minimum of 108 FPS and maximum of 146 FPS. High averages 107 FPS. Ultra averages 82 FPS. The progression from Low to Ultra shows a steady decline, with the largest single drop occurring between Low and Medium (63 FPS), while the drop from Medium to High is 20 FPS and from High to Ultra is 25 FPS.

At 2560x1440, Low averages 130 FPS. Medium averages 88 FPS, with a minimum of 74 FPS and maximum of 101 FPS. High averages 74 FPS. Ultra averages 56 FPS. The difference between Low and Medium is 42 FPS, between Medium and High is 14 FPS, and between High and Ultra is 18 FPS. The diminishing returns of higher presets are evident here, where the gap between Medium and High is smaller than the gap between Low and Medium.

At 3840x2160, Low averages 77 FPS. Medium averages 52 FPS, with a minimum of 44 FPS and maximum of 59 FPS. High averages 44 FPS. Ultra averages 33 FPS. The Low to Medium drop is 25 FPS, Medium to High is 8 FPS, and High to Ultra is 11 FPS. At this resolution, the higher presets cluster together, all landing between 33 and 52 FPS, while Low stands apart at 77 FPS.

Comparing across resolutions, the 1080p Low figure of 190 FPS is the highest any preset achieves. The 1440p Low figure of 130 FPS is 68% of that value. The 4K Low figure of 77 FPS is 41% of the 1080p Low figure. For the Ultra preset, the 1080p value of 82 FPS falls to 56 FPS at 1440p (68%) and 33 FPS at 4K (40%). The consistency of these percentage drops across presets indicates that resolution scaling behaves similarly regardless of quality level, which is typical for a GPU-bound workload.

CPU Role

The AMD Ryzen 7 5700 is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. It has 16 MB of L3 cache, 512 KB of L2 cache per core, and 64 KB of L1 cache per core. The CPU's 3DMark scores show a single-thread result of 901, a 2-thread score of 1762, a 4-thread score of 3382, an 8-thread score of 5585, and a 16-thread score of 6628. The max-thread score of 6617 is nearly identical to the 16-thread score, indicating that the processor scales well up to its full thread count but gains little beyond that.

In Cinebench, the R15 multicore score is 2082 and single-core is 293; R20 multicore is 8675 and single-core is 1224; R23 multicore is 20655 and single-core is 2916. The Geekbench scores are 9959 for multicore and 1907 for single-core. These figures place the CPU at the 78th percentile among all CPUs, with an average benchmark score of 25517. Its nearest rivals include the Intel Xeon D-2752TER (25530, delta -0.1%), the AMD Ryzen 5 7640U (25485, delta 0.1%), the Ryzen 5 6600H (25550, delta -0.1%), and the Ryzen 7 5825U (25446, delta 0.3%). All of these rivals are within 0.3% of the 5700's average score, making them effectively equivalent in synthetic performance.

In Rust, the CPU's role is most apparent at 1080p Low, where the 190 FPS average suggests that the processor is keeping up with the GPU's output. The single-thread performance, as measured by the 3DMark single-thread score of 901 and the Cinebench R23 single-core score of 2916, is sufficient to drive high frame rates in a game that emphasizes world simulation and entity updates. The 8-core, 16-thread configuration provides ample headroom for background tasks and the game's multithreaded systems, though the scaling from 8 to 16 threads is minimal, as shown by the 3DMark scores.

The CPU's memory support is DDR4 with dual-channel configuration and a bandwidth of 51.2 GB/s, which is a potential limiting factor in a game like Rust that streams large amounts of world data. However, the measured frame rates do not show obvious stuttering or a collapse at low resolutions, which would indicate a memory bottleneck. The 65W TDP and the Cezanne codename suggest a power-efficient design that can sustain its boost clock under load, contributing to consistent frame delivery.

How This Combo Ranks

In the database of tested combinations for Rust, this specific pairing of the AMD Ryzen 7 5700 and the AMD Radeon RX 7700 XT ranks 1380 out of 3723 total combos. That places it in the 63rd percentile of tested systems, meaning it outperforms roughly 63% of all recorded combinations. This is a solid mid-to-upper tier ranking, consistent with the individual component percentiles: the CPU at the 78th percentile and the GPU at the 67th percentile.

The ranking suggests that this combination is well-balanced for Rust, with neither component dragging the other down significantly. The CPU's strong multithreaded performance, evidenced by its Cinebench R23 multicore score of 20655, likely helps in Rust's server-side and simulation-heavy moments, while the GPU's 12 GB VRAM and 432.0 GB/s bandwidth handle the game's texture streaming and rendering demands. The fact that the combo ranks higher than the GPU's individual percentile (67th) in this game suggests that Rust's workload favors the CPU's capabilities, or that the GPU is being utilized efficiently without being the sole bottleneck.

Compared to other combos in the database, this ranking of 1380 out of 3723 is respectable but not exceptional. It indicates that there are many faster combinations, likely pairing higher-end CPUs and GPUs, but also that this combo beats a substantial majority of tested systems. The measured frame rates at 1080p and 1440p are high enough for smooth gameplay, and the 4K performance, while not stellar, is usable at lower presets. This ranking reflects a system that can handle Rust well at mainstream resolutions and settings, with the understanding that 4K Ultra is beyond its comfortable reach.
