Rust

Rust with an AMD Ryzen 5 7500X3D and NVIDIA GeForce RTX 3070 Ti produces a wide spread of frame rates that narrows significantly as resolution climbs. At 1080p Low, the combo delivers 194 FPS average, but that falls to 110 FPS at High and 84 FPS at Ultra. Moving to 1440p, the Low preset still manages 134 FPS, while High drops to 76 FPS and Ultra lands at 58 FPS. At 4K, the picture changes dramatically: Low yields 79 FPS, Medium 53 FPS, High 45 FPS, and Ultra just 34 FPS. The scaling pattern from 1080p to 4K shows a 57% reduction in average FPS between 1080p Low and 4K Low, and a 59% reduction between 1080p High and 4K High. This steep drop-off indicates that at 4K, the GPU becomes the dominant constraint, whereas at 1080p the CPU has more headroom to push frame rates higher, especially on Low settings where the gap between 1080p and 1440p is 60 FPS.

Resolution Scaling

The FPS progression across resolutions reveals where the bottleneck shifts. At 1080p Low, the system produces 194 FPS, which is an exceptionally high figure that suggests the CPU is capable of feeding the GPU well beyond what most titles demand. When resolution increases to 1440p at the same Low preset, average FPS falls to 134, a 31% drop. That decline accelerates at 4K Low, which lands at 79 FPS — a further 41% reduction from 1440p. For High settings, the pattern is similar but with lower absolute values: 110 FPS at 1080p, 76 FPS at 1440p, and 45 FPS at 4K. The percentage drops between consecutive resolutions for High are 31% (1080p to 1440p) and 41% (1440p to 4K), mirroring the Low preset's scaling almost exactly. This consistency suggests that the GPU's workload scaling with pixel count is the primary factor, not CPU limitations, since the relative declines are uniform across presets.

The Medium settings row provides additional insight because it includes min and max FPS values. At 1080p Medium, the average is 130 FPS with a range of 111 to 150 FPS. At 1440p Medium, the average drops to 90 FPS with a range of 76 to 103 FPS. At 4K Medium, the average falls to 53 FPS with a range of 45 to 61 FPS. The spread between min and max narrows as resolution increases: 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K. This tightening range indicates that at lower resolutions, CPU-side frame time variability causes larger FPS fluctuations, while at 4K the GPU's consistent workload smooths out the frame pacing. The data points to a system that is well-balanced at 1440p, where the CPU and GPU both contribute meaningfully, but at 4K the RTX 3070 Ti's 8 GB of VRAM and memory bandwidth become the limiting factors.

How This Combo Ranks

Within the benchmark database, this specific CPU-GPU combination ranks 979th out of 2,953 tested combos for Rust. That places it in the top third of all configurations, which is notable given the game's demanding nature. The rank reflects the measured FPS across all resolutions and settings, weighting the overall performance profile. The combo's position suggests that while it is not among the elite tier of systems capable of 4K Ultra at high refresh rates, it delivers strong playable performance at more common resolutions. The ranking also implies that the Ryzen 5 7500X3D and RTX 3070 Ti pair well together, with neither component dragging the other down excessively. However, the rank is not exceptional, indicating that there are many faster combinations available, particularly those with higher-end GPUs or newer architectures.

The percentile data for the individual components supports this interpretation. The CPU has a percentile rank of 89 against all CPUs, meaning it outperforms 89% of processors in general benchmark tests. The GPU's percentile rank is 75 against all GPUs, which is lower but still above average. The disparity in percentiles suggests that the CPU is relatively stronger than the GPU in this pairing. For Rust specifically, the combo rank of 979 out of 2,953 shows that the pairing does not punch above its weight class; it performs roughly in line with what the component percentiles would predict. The nearest rival CPUs, such as the Intel Core i5-14600 with a 0.7% higher average score, and the Intel Core i9-13950HX with a 0.5% lower score, show that the 7500X3D is competitive within a tight band of processors. Similarly, the GPU's nearest rivals include the RTX 5070 Mobile (0.1% higher) and RX 6800 (0.5% higher), indicating the 3070 Ti sits comfortably in its performance tier.

CPU Role

The AMD Ryzen 5 7500X3D brings a specific set of characteristics to Rust: 6 cores and 12 threads, with a base clock of 4.00 GHz and a boost clock of 4.50 GHz. This is a 7000-series chip built on the Raphael codename and Zen 4 architecture, manufactured on TSMC's 5 nm process. The CPU has 96 MB of shared L3 cache, which is a substantial amount that can benefit games with large working sets. For Rust, a survival game with complex world interactions and physics, cache size can matter more than raw core count. The 7500X3D's L3 cache is significantly larger than typical desktop CPUs, and this likely contributes to the strong 1080p Low performance of 194 FPS, where CPU-bound scenarios are more common.

In the benchmark data, the CPU's PassMark multithread score is 25,047, and its single-thread score is 3,494. The multithread score places it in the 89th percentile of all CPUs, while the single-thread score is more modest. The nearest rivals in the CPU benchmark database include the Intel Core i9-13950HX with an average score of 44,342 (0.5% lower) and the Intel Core i5-14600 with 44,889 (0.7% higher), showing that the 7500X3D's overall average of 44,573 is right in the middle of a competitive pack. For Rust specifically, the CPU's 6-core/12-thread configuration is sufficient, as the game does not scale linearly beyond 8 threads or so. The boost clock of 4.50 GHz provides adequate per-core performance for the game's single-threaded aspects, while the L3 cache helps with the procedural world generation and entity updates that Rust performs frequently. The CPU's TDP of 65 W is relatively low, which means it can sustain boost clocks without thermal throttling in most systems, supporting consistent frame delivery.

Measured FPS Breakdown

At 1920x1080, the measured FPS spans from 194 FPS on Low to 84 FPS on Ultra, with High at 110 FPS and Medium at 130 FPS. The Medium setting shows a min of 111 FPS and max of 150 FPS, giving a 39 FPS range. These numbers indicate that at 1080p, the system has ample performance for high-refresh-rate monitors on Low and Medium, but Ultra drops below the 100 FPS threshold that many gamers consider essential. The step from Low to Medium costs 64 FPS, while Medium to High costs another 20 FPS, and High to Ultra costs an additional 26 FPS. This suggests that the Low preset removes many GPU-intensive effects that have outsized performance impacts.

At 2560x1440, the averages are 134 FPS (Low), 90 FPS (Medium), 76 FPS (High), and 58 FPS (Ultra). The Medium setting's range is 76 to 103 FPS, a 27 FPS spread. The 1440p results show that Low and Medium are both playable at high refresh rates, but High drops to below 80 FPS, which may be noticeable on 144 Hz displays. The Ultra setting at 58 FPS is still smooth for most players but falls short of high-refresh standards. The scaling from 1080p to 1440p for each preset is: Low drops 60 FPS (31%), Medium drops 40 FPS (31%), High drops 34 FPS (31%), and Ultra drops 26 FPS (31%). This uniform 31% reduction across all presets strongly indicates that the GPU fill rate is the limiting factor, as the percentage drop is identical regardless of settings.

At 3840x2160, the numbers become more constrained: 79 FPS (Low), 53 FPS (Medium), 45 FPS (High), and 34 FPS (Ultra). The Medium setting ranges from 45 to 61 FPS, a 16 FPS spread. At 4K, only Low approaches playable territory for competitive play, while Medium and High are acceptable for single-player experiences. Ultra at 34 FPS is borderline, and the 8 GB VRAM on the RTX 3070 Ti likely contributes to the steep drop at this resolution and preset. The scaling from 1440p to 4K for each preset is: Low drops 55 FPS (41%), Medium drops 37 FPS (41%), High drops 31 FPS (41%), and Ultra drops 24 FPS (41%). Again, the percentage drop is consistent at 41%, further confirming that resolution scaling is the dominant factor, and the GPU's compute and memory resources are the bottleneck at 4K.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture with a GA104 chip, manufactured on Samsung's 8 nm process. It has 8 GB of GDDR6X memory on a 256-bit bus, providing 608.3 GB/s of bandwidth. The GPU's base clock is 1575 MHz with a boost clock of 1770 MHz, and it houses 6,144 shading units, 192 TMUs, and 96 ROPs. The memory clock runs at 1188 MHz, translating to 19 Gbps effective. These specifications place the GPU in the 75th percentile of all GPUs, with an average benchmark score of 29,945. Its nearest rivals include the RTX 5070 Mobile (0.1% higher), RX 6800 (0.5% higher), and RTX 2080 Ti (0.5% lower), showing that the 3070 Ti sits in a well-contested performance band.

For Rust, the GPU's role becomes more critical as resolution and settings increase. At 1080p Low, the GPU is not the limiting factor, as the CPU can feed it frames faster than it can render them, resulting in 194 FPS. But at 4K Ultra, the GPU's 8 GB VRAM is likely insufficient for the game's high-resolution textures, and the 34 FPS average reflects this constraint. The pixel rate of 169.9 GPixel/s and texture rate of 339.8 GTexel/s are moderate for a GPU of this class, and the FP32 performance of 21.75 TFLOPS is competitive but not exceptional. The 4K Medium result of 53 FPS with a min of 45 FPS suggests that the GPU can handle moderate settings at 4K, but the frame time variability increases as the workload pushes closer to the memory bandwidth limit. The 608.3 GB/s bandwidth is sufficient for 1440p, but at 4K with Ultra settings, the 8 GB capacity becomes a hard ceiling that forces texture streaming and can cause stutters, which the data hints at with the wide min-max spread.

The GPU's DirectX 12 benchmark score of 91 in PassMark is notably low compared to its other scores, which might indicate that the card's performance in modern APIs is not fully represented by synthetic tests. However, the Vulkan score of 139,541 and OpenCL score of 119,718 show stronger results. For Rust, which uses a custom engine, the GPU's raw throughput matters more than API-specific optimizations. The RTX 3070 Ti's 48 RT cores and 192 tensor cores are present but not heavily utilized in Rust, as the game does not feature ray tracing as a core requirement. The GPU's 290 W TDP and 600 W suggested PSU indicate it is a power-hungry component, but that does not directly impact FPS measurements.
