Rust

The Intel Core i7-12700K paired with the NVIDIA GeForce RTX 3080 Ti in Rust produces a dataset that clearly separates CPU-bound and GPU-bound operating points. At 1080p Low, the combo reaches 223.6 FPS, which is nearly 2.4 times the 4K Ultra result of 40.4 FPS. This massive spread—a 183.2 FPS difference between the lowest and highest workload—reveals that Rust scales aggressively with resolution and settings, and the limiting component shifts depending on the configuration. The data suggests that at lower resolutions, the processor is doing the heavy lifting, while at 4K Ultra, the graphics card is the primary constraint.

Resolution Scaling

The FPS drop from 1080p to 4K is steep across all settings, but the rate of decline is not uniform. At Low settings, 1080p yields 223.6 FPS, 1440p drops to 157.2 FPS, and 4K falls to 92.5 FPS. That is a 58.6% reduction from 1080p to 1440p, and a further 41.1% reduction from 1440p to 4K. The scaling is more severe at Ultra: 1080p gives 97 FPS, 1440p gives 69.8 FPS, and 4K gives 40.4 FPS—a 58.4% drop from 1080p to 4K overall.

The pattern implies that Rust is not purely GPU-bound at lower resolutions. At 1080p Low, the RTX 3080 Ti is likely idling while the i7-12700K drives the frame rate, which explains why the FPS is so high. At 4K Ultra, the GPU is saturated, and the FPS falls to a level consistent with a graphics-heavy workload. The medium settings show a middle ground: 153.7 FPS at 1080p, 105.4 FPS at 1440p, and 59 FPS at 4K. The fact that 4K Medium (59 FPS) is barely above 1440p Ultra (69.8 FPS) suggests that resolution has a larger impact than the preset step in this range.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor from the Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its benchmark results place it in the 89th percentile of all CPUs, with an average score of 35684. In Rust, the CPU's role is most evident at 1080p Low, where the combo achieves 223.6 FPS—a figure that likely exceeds what the GPU alone could produce if it were the sole bottleneck.

Comparing the processor to its nearest rivals, the i7-12700K scores 0.3% lower than the AMD Ryzen 7 PRO 5845, 0.6% higher than the Intel Core i7-13700T, 0.7% lower than the Intel Core i5-14500HX, and 0.8% higher than the Intel Core i7-13800H. These deltaPct values are all within a single percentage point, meaning the CPU is effectively performance-equivalent to its closest competitors in synthetic benchmarks. However, in Rust, the measured FPS at lower resolutions shows headroom, implying that the CPU's single-thread performance—boost clock of 5.00 GHz and a 3DMark single-thread score of 1043—is sufficient to feed the GPU at 1080p.

The data suggests the CPU is not a limiting factor at 4K, where the FPS is governed by the GPU. At 1080p Low, the CPU's multi-threaded capabilities (Cinebench R23 multicore score of 29241) may help with Rust's simulation and physics, but the game is likely more dependent on the high boost clock for frame pacing. The difference between 1080p Low (223.6 FPS) and 1440p Low (157.2 FPS) is 66.4 FPS, which is larger than the 49.7 FPS difference between 1440p Low and 4K Low, indicating that resolution scaling is not linear and the CPU becomes less relevant as pixel count increases.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is an Ampere-architecture GPU with 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. Its boost clock is 1665 MHz, and it has 10240 shading units. The GPU places in the 83rd percentile of all GPUs, with an average benchmark score of 41224. In Rust, the GPU's role is most pronounced at 4K, where the FPS ranges from 40.4 at Ultra to 92.5 at Low.

At 4K Ultra, the 40.4 FPS result indicates the GPU is heavily loaded, likely due to the combination of high resolution and demanding graphical effects. The 4K Medium result of 59 FPS and 4K High of 49.6 FPS show a clear hierarchy: Low is 87.1% faster than Ultra, and Medium is 46.0% faster than Ultra. This suggests that the GPU's memory bandwidth and compute resources are the limiting factors at 4K, and the 12 GB VRAM is sufficient for the game's needs at these settings.

Comparing the GPU to its nearest rivals, the RTX 3080 Ti scores 0.5% lower than the NVIDIA GeForce RTX 3090, 0.9% lower than the AMD Radeon Pro 5300, 1.1% lower than the NVIDIA GeForce RTX 5070, and 1.6% lower than the NVIDIA Tesla M40. These small deltas indicate the GPU is competitive with these parts. At 1080p, the GPU's role is less critical—the FPS at Low (223.6) is 2.3 times higher than at Ultra (97), but the CPU is likely the bottleneck at Low, making the GPU underutilized.

Settings Recommendations

The measured rows provide a clear picture of which preset offers the best experience. At 1080p, Low yields 223.6 FPS, which is excellent for high-refresh monitors, but the 153.7 FPS at Medium is a more balanced choice, offering a 31.2% FPS reduction from Low while presumably improving visual quality. High at 1080p drops to 125.4 FPS, and Ultra falls to 97 FPS. For most users, Medium at 1080p is the sweet spot, as it maintains a high frame rate while likely reducing graphical artifacts.

At 1440p, Low gives 157.2 FPS, Medium gives 105.4 FPS, and High gives 90.1 FPS. The step from Low to Medium is a 33.0% drop, but the step from Medium to High is a 14.5% drop, suggesting diminishing returns. Ultra at 1440p is 69.8 FPS, which is playable but less fluid. For 1440p, Medium is recommended for a balance of smoothness and quality, as it is 51.0% faster than Ultra.

At 4K, Low is the only preset that breaks 90 FPS (92.5), while Medium (59) and High (49.6) fall below 60 FPS. Ultra (40.4) is the least desirable. Given the data, 4K users should stick to Low for competitive play, or Medium if they can tolerate a lower frame rate for better visuals. The 4K Low result is 129.0% faster than 4K Ultra, making it the clear choice for performance.

How This Combo Ranks

This combination of the Intel Core i7-12700K and NVIDIA GeForce RTX 3080 Ti ranks 358th out of 1717 tested combos in Rust, placing it in the top 20.8% of all tested configurations. This rank reflects the combo's strong performance, particularly at lower resolutions, where the CPU and GPU work well together. The rank is likely influenced by the GPU's 83rd percentile standing and the CPU's 89th percentile standing, both of which are high.

The rank of 358 out of 1717 means there are 1359 combos that perform worse, but 357 that perform better. Given the CPU's nearest rivals are within 1% of its benchmark score, the ranking is more dependent on the GPU. The RTX 3080 Ti's nearest rival, the RTX 3090, is only 0.5% faster in synthetic benchmarks, so the combo's rank could shift with different GPU pairings. In Rust specifically, the data indicates that the combo is well-suited for high-refresh 1080p and 1440p gaming, but at 4K, the GPU becomes the bottleneck, pulling the rank down relative to combos with more powerful GPUs.

Measured FPS Breakdown

At 3840x2160, the FPS ranges from 40.4 at Ultra to 92.5 at Low. The breakdown is: Low 92.5, Medium 59, High 49.6, and Ultra 40.4. The difference between Low and Medium is 33.5 FPS, between Medium and High is 9.4 FPS, and between High and Ultra is 9.2 FPS.

Across all resolutions, the FPS gap between Low and Ultra is consistent in relative terms: 1080p sees a 56.6% drop, 1440p sees a 55.6% drop, and 4K sees a 56.3% drop. This suggests that the settings scaling is resolution-independent, while the absolute FPS values are governed by resolution.
