Rust

Rust’s benchmark results for the Intel Core i7-12700K paired with the AMD Radeon RX 7700 reveal a configuration that is heavily influenced by resolution and graphics settings. The data shows a clear progression from CPU-bound territory at 1080p to GPU-bound behavior at 4K, with the mid-range settings offering the most balanced experience. This analysis breaks down the measured FPS across all combinations to understand where this combo excels and where it struggles.

Resolution Scaling

The measured FPS data shows a steep and consistent drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate falls from 173 FPS at 1080p to 119 FPS at 1440p, then to 70 FPS at 4K. This represents a 31% decrease from 1080p to 1440p and a further 41% decrease from 1440p to 4K. The scaling pattern indicates that at 1080p Low, the CPU is the primary limiting factor, as the GPU has ample headroom to render frames quickly but is constrained by the processor’s ability to feed it data.

Moving to High settings, the average FPS drops from 98 at 1080p to 67 at 1440p, then to 40 at 4K. The percentage drops here are 32% and 40% respectively, which is remarkably similar to the Low settings scaling. This consistency suggests that the resolution scaling is driven primarily by pixel count and GPU fill rate rather than by settings complexity. The gap between Low and High at each resolution narrows as resolution increases: at 1080p, Low beats High by 75 FPS, but at 4K, the gap shrinks to 30 FPS. This compression indicates that at higher resolutions, the GPU workload becomes so dominant that the CPU’s ability to process game logic and draw calls matters less.

The Medium settings row provides the only min/max FPS data in the pack. At 1080p Medium, the average is 116 FPS with a min of 99 and max of 133, showing a 34 FPS spread. At 1440p Medium, the average drops to 80 FPS with a min of 68 and max of 92, a 24 FPS spread. At 4K Medium, the average falls to 47 FPS with a min of 40 and max of 54, a 14 FPS spread. This narrowing min/max range as resolution increases further confirms that GPU-bound scenarios produce more stable frame pacing, while CPU-bound scenarios at lower resolutions exhibit larger fluctuations. The data suggests that at 4K, the RX 7700 is the clear bottleneck, while at 1080p, the i7-12700K’s 12 cores and 20 threads are the limiting factor.

FAQ

Q: What is the highest average FPS this combo achieves in Rust?

A: The highest measured average FPS is 173, achieved at 1920x1080 resolution with Low settings. This is a CPU-bound scenario where the GPU is not the limiting factor.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS drops to 30. This is the lowest measured result in the entire dataset, indicating that Ultra settings at 4K are too demanding for this GPU.

Q: What is the FPS difference between Low and High settings at 1440p?

A: At 2560x1440, Low settings produce an average of 119 FPS, while High settings produce 67 FPS. This is a 52 FPS difference, showing that settings changes have a significant impact on performance at this resolution.

Q: Does the GPU’s 16 GB VRAM help at 4K?

A: The GPU has 16 GB of GDDR6 memory, which is more than sufficient for Rust’s texture demands. However, the benchmark data shows that at 4K, the limiting factor is raw compute power, not memory capacity, as even Medium settings only reach 47 FPS.

Q: How does the combo rank among all tested combinations in Rust?

A: This combo ranks 1295th out of 2953 total tested combinations. This places it in the 44th percentile, meaning roughly 56% of tested combos perform better in this game.

Q: What settings provide the best balance for 60 FPS gameplay at 1440p?

A: At 2560x1440, Medium settings achieve 80 FPS average, which comfortably exceeds 60 FPS. High settings at the same resolution produce 67 FPS, still above 60, while Ultra drops to 51 FPS, below the 60 FPS threshold.

GPU Role

The AMD Radeon RX 7700 plays the dominant role in determining performance at higher resolutions. Its 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth, which is ample for Rust’s asset streaming. The GPU’s boost clock of 2459 MHz and game clock of 2041 MHz define its compute throughput, and the benchmark scores reflect a mid-pack performer. The GPU’s percentile rank among all GPUs is 58, placing it slightly above the median. Its PassMark G3D score of 20974 is the most relevant metric for gaming performance, and it sits just 0.1% above the AMD Radeon R9 370X in average score, though the RX 7700 is clearly a more modern architecture.

At 1080p, the GPU is underutilized. The data shows that even at Ultra settings, the average FPS is 75, which is well below what the GPU could theoretically produce if the CPU could keep up. The CPU’s frame delivery becomes the bottleneck, as evidenced by the fact that Low settings produce 173 FPS but Ultra only 75 FPS—a 98 FPS swing that is more attributable to CPU-driven game logic than GPU pixel throughput. At 4K, the tables turn. The GPU’s fill rate and shader throughput are insufficient to maintain high frame rates, as seen by the 40 FPS average at High and 30 FPS at Ultra. The GPU’s FP32 performance of 25.18 TFLOPS is not enough to handle the pixel workload at 4K with high-quality settings.

The GPU’s direct relevance to Rust’s results is clear: it determines the ceiling at 4K and the floor at 1080p. The 16 GB VRAM is never a limiting factor in these measurements, as even the highest settings at 4K do not show a VRAM-related stutter or crash in the data. The GPU’s RDNA 3.0 architecture with 2560 shading units and 96 ROPs provides the raw pixel throughput that governs 4K performance, while its 160 TMUs handle texture filtering. The data indicates that for this game, the GPU is the primary determinant of performance at resolutions above 1440p.

How This Combo Ranks

In the overall database of tested hardware combinations for Rust, this specific pairing of Intel Core i7-12700K and AMD Radeon RX 7700 ranks 1295th out of 2953 total combos. This places it in the 44th percentile of all tested systems, meaning it outperforms 44% of the field. The rank is a composite measure that accounts for all resolution and settings combinations, so it reflects the combo’s behavior across the entire test suite rather than a single scenario.

The rank of 1295 is notable because it is lower than what either component’s individual benchmark scores might suggest. The CPU’s average benchmark score of 35287 places it in the 84th percentile among all CPUs, with nearest rivals including the Intel Core i5-13600T (0.1% higher score) and Intel Core i7-12700KF (0.2% higher). The GPU’s average score of 15852 places it in the 58th percentile among all GPUs, with its nearest rival being the AMD Radeon R9 370X at 0.1% higher. If both components were performing at their individual percentile levels, one might expect a higher combo rank. The fact that the combo ranks in the 44th percentile suggests that Rust is particularly demanding on the combination, or that the GPU’s mid-pack performance drags down the overall result more than the CPU’s strong showing can compensate.

The gap between the CPU’s 84th percentile rank and the combo’s 44th percentile rank indicates that Rust is not a CPU-bottlenecked game at the resolutions where the GPU is stressed. The combo’s rank of 1295 out of 2953 means there are 1658 combos that perform better in this game, which is a significant number. This suggests that for Rust specifically, the RX 7700’s performance level is below what many other GPU options offer, even when paired with a high-end CPU. The data shows that this combo is better suited for 1080p and 1440p gaming, where it ranks higher in relative performance, rather than 4K, where the GPU’s limitations become apparent.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor based on Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its 25 MB of shared L3 cache and 1.25 MB per-core L2 cache provide substantial on-die storage for game data. The CPU’s benchmark scores are strong: it achieves 19784 in Cinebench R23 multi-core and 1850.5 in single-core, with a PassMark multi-thread score of 34404. Its percentile rank of 84 among all CPUs confirms it is a high-end processor. In Rust, the CPU’s role is most evident at 1080p and Low settings, where the measured 173 FPS suggests the CPU is capable of feeding the GPU at high rates.

The CPU’s 12 cores and 20 threads are relevant to Rust because the game is known for its complex entity and physics simulations, which can scale across multiple threads. The benchmark data supports this: at 1080p Low, the CPU is able to push the GPU to 173 FPS, but at 1080p Ultra, the FPS drops to 75. This 98 FPS drop is not attributable to GPU pixel work alone, because at 4K Low, the GPU still manages 70 FPS. The implication is that at 1080p Ultra, the CPU is still the bottleneck, but the additional settings workload (lighting, shadows, and draw distance) taxes the CPU’s threads more heavily, reducing its ability to maintain high frame rates.

The CPU’s boost clock of 5.00 GHz is a key factor in single-threaded performance, which Rust relies on for its main game loop. The 3dmark single-thread score of 1043 and PassMark single-thread score of 4013 indicate strong per-core performance. However, the data shows that even this CPU cannot fully overcome the GPU’s limits at 4K, where the 40 FPS at High settings is far below what the CPU could drive. The CPU’s role in Rust is to provide a high frame rate ceiling at lower resolutions, and the data confirms it does this well. At 1080p Low, the i7-12700K is clearly capable of exceeding 173 FPS, as the GPU is likely the limiting factor even at that resolution.

The CPU’s 20 threads are also relevant for background tasks and game server hosting, though the benchmark data does not directly measure those scenarios. What the data does show is that the CPU’s performance is consistent across resolutions until the GPU becomes the bottleneck. At 1440p High, the CPU is still able to drive 67 FPS, which is respectable, but at 4K High, the CPU’s advantage is nullified by the GPU’s inability to render frames fast enough. The CPU’s 84th percentile rank among all CPUs is not reflected in the combo’s overall rank, indicating that Rust’s performance ceiling is set by the GPU in most of the tested scenarios.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo’s performance across four resolutions and four settings levels. At 1920x1080, the results are: Low 173 FPS, Medium 116 FPS (min 99, max 133), High 98 FPS, and Ultra 75 FPS. The progression shows a steady decline as settings increase, with Low being 75 FPS higher than Medium and 98 FPS higher than High. This indicates that at 1080p, the CPU is the primary bottleneck, as the GPU has enough headroom to render at high speeds but is limited by the CPU’s frame delivery.

At 2560x1440, the results are: Low 119 FPS, Medium 80 FPS (min 68, max 92), High 67 FPS, and Ultra 51 FPS. The drop from 1080p to 1440p is significant: Low loses 54 FPS, Medium loses 36 FPS, High loses 31 FPS, and Ultra loses 24 FPS. The smaller absolute drops at higher settings indicate that the GPU is becoming more of a limiting factor, but the CPU still has influence. The 119 FPS at Low is still above 100, suggesting that the CPU is still capable at this resolution, but the 51 FPS at Ultra shows that the GPU is struggling with the pixel count and settings complexity.

At 3840x2160, the results are: Low 70 FPS, Medium 47 FPS (min 40, max 54), High 40 FPS, and Ultra 30 FPS. The drop from 1440p to 4K is dramatic: Low loses 49 FPS, Medium loses 33 FPS, High loses 27 FPS, and Ultra loses 21 FPS. At 4K, the GPU is clearly the limiting factor, as even Low settings only achieve 70 FPS, which is below the 119 FPS at 1440p Low. The Ultra setting at 4K is the only sub-60 FPS result across all tests, hitting exactly 30 FPS, which is half of the 60 FPS target.

The Medium settings rows are the only ones with min/max data. At 1080p, the min is 99 and max is 133, a 34 FPS spread. At 1440p, the min is 68 and max is 92, a 24 FPS spread. At 4K, the min is 40 and max is 54, a 14 FPS spread. This narrowing range as resolution increases reinforces the idea that higher resolutions produce more consistent frame times due to GPU-bound operation, while lower resolutions show more variance due to CPU scheduling and game logic spikes.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution. For 1920x1080, the data shows that High settings at 98 FPS provide the best balance between visual quality and performance. Medium settings at 116 FPS offer a 18 FPS improvement but at a noticeable visual downgrade, while Ultra at 75 FPS is still playable but sacrifices 23 FPS compared to High. The data supports choosing High at 1080p for a smooth experience that maximizes visual fidelity without dropping below 60 FPS.

For 2560x1440, the recommendation is Medium settings, which achieve 80 FPS with a min of 68 and max of 92. This is the only settings level at 1440p that comfortably exceeds 60 FPS while providing a reasonable visual quality. High settings at 67 FPS are also above 60 FPS, but the margin is thinner, and the min FPS data is not available for High. Ultra at 51 FPS falls below 60 FPS and is not recommended for smooth gameplay. Low at 119 FPS is the highest FPS option but sacrifices too much visual quality for the average user.

At 3840x2160, the data shows that no settings level achieves 60 FPS. Low settings at 70 FPS is the only option that exceeds 60 FPS, making it the only viable choice for 4K gaming if frame rate is a priority. Medium at 47 FPS and High at 40 FPS are playable but below the 60 FPS target, while Ultra at 30 FPS is borderline unplayable for most users. The recommendation for 4K is to use Low settings, which offers a 23 FPS improvement over Medium and a 30 FPS improvement over High, while still providing a playable experience.

The overall recommendation across all resolutions is to prioritize Medium settings at 1440p as the best balance of performance and quality, as it delivers 80 FPS with a stable frame time range. For users with 1080p monitors, High settings provide a slightly better experience at 98 FPS. For 4K users, the data suggests that this combo is not ideal, and Low settings are the only way to maintain a playable frame rate.
