Rust

Rust is a demanding survival title where frame rates are heavily influenced by both the CPU and GPU, and the combination of the Intel Core i7-12700KF and NVIDIA GeForce RTX 5090 produces a wide spread of performance depending on resolution and settings. At 1080p with Low settings, the combo delivers an average of 233 FPS, which drops to 201 FPS at Medium, 185 FPS at High, and 140 FPS at Ultra. Moving to 1440p, the averages are 206 FPS at Low, 150 FPS at Medium, 127 FPS at High, and 97 FPS at Ultra. At 4K, the frame rates become more demanding, with 132 FPS at Low, 89 FPS at Medium, 75 FPS at High, and 57 FPS at Ultra. The scaling from 1080p to 4K shows a significant performance cost, with the Low preset dropping from 233 FPS to 132 FPS, a reduction of roughly 43%, while the High preset falls from 185 FPS to 75 FPS, a 59% decline.

Resolution Scaling

The data reveals a clear trend: as resolution increases, the average frame rate steadily decreases, but the magnitude of the drop varies by settings preset. At Low settings, the transition from 1920x1080 to 2560x1440 reduces the average from 233 FPS to 206 FPS, a modest 12% decline, but moving from 1440p to 4K cuts it down to 132 FPS, a further 36% reduction. This suggests that at lower graphical presets, the CPU is able to keep up with the GPU even as pixel count rises, but the GPU becomes the limiting factor at 4K. For the Medium preset, the frame rates are 201 FPS at 1080p, 150 FPS at 1440p, and 89 FPS at 4K, with the 4K result being 56% lower than the 1080p figure, indicating a more balanced load between components. The High preset shows a steeper curve, with 185 FPS at 1080p, 127 FPS at 1440p, and 75 FPS at 4K, where the 4K average is 59% below the 1080p value, pointing to the GPU being increasingly stressed. Ultra settings produce the lowest numbers, with 140 FPS at 1080p, 97 FPS at 1440p, and 57 FPS at 4K, and the gap between 1080p and 4K is 59% as well.

The limiting component shifts depending on the resolution and preset. At 1080p Low, the 233 FPS result is close to what the CPU can push, and the RTX 5090 has headroom, as evidenced by the relatively small drop to 206 FPS at 1440p. At 4K Ultra, the 57 FPS average is heavily constrained by the GPU, since the pixel workload grows exponentially, and the CPU’s 12 cores and 20 threads are less relevant at that point. The 4K Medium row includes a minimum FPS of 76 and maximum of 102, while the 1440p Medium row shows 128 minimum and 173 maximum, and 1080p Medium shows 170 minimum and 231 maximum; these ranges indicate that frame pacing is consistent at lower resolutions but becomes more variable at 4K. The data indicates that for smooth 4K play, users should expect to lower settings, as even High settings only achieve 75 FPS, which is below the 90 FPS mark that many gamers target for competitive play.

How This Combo Ranks

In the broader context of tested hardware combinations for Rust, this specific pairing of the Core i7-12700KF and RTX 5090 ranks at position 95 out of 3723 combos, placing it in the top 2.5% of all tested systems. This percentile ranking is strong, but it is not the absolute top, suggesting that there are a few other combinations that deliver higher average frame rates in this title. The components themselves have high individual percentile scores, with the CPU at 85th percentile versus all CPUs and the GPU at 92nd percentile versus all GPUs, which aligns with the combo’s strong overall position. The fact that the combo rank is lower than the GPU’s individual percentile suggests that Rust’s performance is not purely GPU-bound in all scenarios, and the CPU’s 85th percentile score may be a slight bottleneck in certain situations, particularly at lower resolutions where frame rates are higher.

When compared to the nearest rivals for the CPU, the Core i7-12700KF is essentially tied with several other Intel parts. The Intel Core i7-13700T has an average benchmark score of 35403, which is 0.1% higher than the 12700KF’s 35365, while the Intel Core 5 213PE scores 35428, a 0.2% difference. The Intel Core i5-13600T and Core i7-12700K are also within 0.2% of the 12700KF, with scores of 35305 and 35287, respectively. These negligible deltas mean that in Rust, the choice between these CPUs would not meaningfully alter the measured frame rates, as they all provide similar raw processing power. For the GPU, the RTX 5090’s nearest rivals include the NVIDIA Tesla P100 PCIe 16 GB, which scores 79605, a 0.3% difference, and the AMD Radeon RX 6850M XT at 78940, which is 1.1% lower; however, these are professional or mobile parts, and in a gaming context, the RTX 5090’s 32 GB of VRAM and Blackwell architecture are more relevant to Rust’s heavy memory usage.

The combo’s rank of 95 out of 3723 means that roughly 96% of tested systems are slower, but it also indicates that the top 94 combinations achieve higher average FPS in Rust. This could be due to other CPUs with higher single-thread performance or other GPUs with better optimization for this specific title. The data shows that the 12700KF has a single-thread score of 1043 in 3DMark and 4071 in Cinebench R23, which are solid but not class-leading, and the RTX 5090’s passmark G3D score of 39650 is very high, yet the combo still ranks outside the top 50. The implication is that Rust rewards a balance of high clock speeds and large cache, and while this combo is excellent, it is not the absolute peak for this game.

CPU Role

The Intel Core i7-12700KF is a 12-core, 20-thread processor based on the Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its cache configuration includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache, which is substantial for a 12th-gen part. In Rust, the game’s mechanics involve many entities, physics calculations, and server-side logic that can utilize multiple threads, and the 20 threads provide ample parallelism for background tasks. The CPU’s benchmark scores reflect its strong multi-threaded performance, with a Cinebench R23 multicore score of 28838 and a Passmark multithread score of 34092, which are high enough to avoid major bottlenecks in most gaming scenarios.

However, Rust is also sensitive to single-thread performance, and the 12700KF’s single-core scores are respectable: 1043 in 3DMark, 1709 in Cinebench R20, and 4071 in Cinebench R23, with a Passmark single-thread score of 3984. The boost clock of 5.00 GHz is crucial for maintaining high frame rates at 1080p, where the CPU is often the limiting factor. At 1080p Low, the 233 FPS average suggests that the CPU can push well over 200 frames per second in less demanding scenes, but the Ultra preset at 140 FPS shows that even with a strong CPU, higher graphical settings increase the per-frame workload and reduce the ceiling. The 3DMark 8-thread score of 7211 and 16-thread score of 9282 indicate that the CPU scales well with thread count, which is beneficial for Rust’s ability to use multiple cores for tasks like terrain loading and entity updates.

The CPU’s 85th percentile ranking versus all CPUs means that it outperforms most processors on the market, but it is not in the top tier. In the nearest rivals, the deltaPct values are all within 0.2%, so there is no meaningful performance gap between the 12700KF and its closest competitors. This suggests that in Rust, the CPU is not the primary differentiator for this combo’s rank; instead, the GPU’s massive power and the overall system balance are more important. The 10 nm process node and 125 W TDP are characteristics of the Alder Lake generation, and while newer CPUs may offer better efficiency, the raw performance of this chip is still sufficient for high-refresh gaming in Rust.

FAQ

Q: Does the CPU’s 20 threads make a difference in Rust?

A: Yes, Rust can utilize multiple threads for various game systems, and the 12700KF’s 20 threads provide headroom for background tasks. The Cinebench R23 multicore score of 28838 indicates strong multi-threaded capability, which helps maintain stable frame rates in busy scenes.

GPU Role

The NVIDIA GeForce RTX 5090 is a flagship graphics card with 32 GB of GDDR7 memory on a 512-bit bus, providing a bandwidth of 1.79 TB/s, which is more than sufficient for Rust’s textures and world data. Its boost clock of 2407 MHz and 21760 shading units offer massive raw compute power, with a FP32 performance of 104.8 TFLOPS, ensuring that the GPU can handle high resolutions and presets without running out of memory. In Rust, the GPU’s role becomes more prominent as resolution increases, and the measured frame rates at 4K demonstrate this shift. At 4K Low, the 132 FPS average is still quite high, but at 4K Ultra, the 57 FPS average shows the GPU is working at its limits, despite having 32 GB of VRAM, which is far beyond what Rust requires.

The GPU’s 92nd percentile ranking versus all GPUs is slightly lower than the RTX 5090’s raw benchmark scores might suggest, but its nearest rivals include the Tesla P100, which is a compute-oriented card, and the Radeon RX 6850M XT, which is a mobile part. In gaming, the RTX 5090’s architecture, Blackwell 2.0, includes 170 ray tracing cores and 680 tensor cores, which are not directly relevant to Rust’s non-ray-traced rendering but contribute to overall efficiency. The passmark G3D score of 39650 is a strong indicator of gaming performance, and the GPU’s 104.8 TFLOPS FP32 throughput ensures that even at 4K, the pixel fill rate of 423.6 GPixel/s is sufficient for the game’s draw calls.

The memory bandwidth of 1.79 TB/s is particularly important for Rust, as the game often loads large map areas and streaming assets. The 32 GB VRAM capacity ensures that there is no memory swapping, even at Ultra settings with high-resolution textures, and the 512-bit bus width allows for fast data transfer. At 1080p, the GPU is often underutilized, as evidenced by the 233 FPS at Low settings, which is likely CPU-bound, but at 4K, the GPU’s 57 FPS at Ultra shows that the pixel workload is the primary constraint. The RTX 5090’s dual-slot design and 575 W TDP are high, but the performance it delivers in Rust is exceptional, making it one of the top GPUs for this game, though the combo’s rank of 95 suggests that other factors, such as CPU memory latency, also play a role.

Settings Recommendations

For users seeking the highest frame rates, the Low preset at 1080p delivers 233 FPS, which is ideal for competitive play or high-refresh-rate monitors. However, the visual quality at Low settings is reduced, and for a more balanced experience, the Medium preset at 1440p provides 150 FPS with a minimum of 128 FPS, ensuring smooth gameplay with better textures and effects. The Medium preset at 1080p offers 201 FPS, which is also excellent, and the minimum of 170 FPS means that frame drops are rare. For those with 4K displays, the High preset at 75 FPS is playable but may not be suitable for fast-paced action, and the Ultra preset at 57 FPS is below the 60 FPS standard, so lowering to Medium at 89 FPS is recommended for a smoother experience.

The data shows that the Medium preset is the sweet spot for this combo, as it provides a significant visual upgrade over Low while maintaining high frame rates across all resolutions. At 1080p Medium, the 201 FPS average is only 32 FPS lower than Low, but the visual improvements are substantial. At 1440p Medium, the 150 FPS average is above the 144 Hz refresh rate of many gaming monitors, making it an excellent choice. At 4K Medium, the 89 FPS average is the only 4K preset that exceeds 60 FPS, and the minimum of 76 FPS ensures that the game remains responsive. The High preset at 1440p, with 127 FPS, is also viable, but the 4K High at 75 FPS may cause noticeable dips in busy areas.

Ultimately, the best settings depend on the user’s display and preference for visual fidelity versus frame rate. For a 240 Hz monitor, the Low preset at 1080p is the only way to reach the highest refresh rates, while for a 144 Hz monitor, the Medium preset at 1440p is optimal. The Ultra preset is only recommended for users who prioritize graphics over performance, as it drops to 140 FPS at 1080p and 57 FPS at 4K, which may not be stable enough for competitive play. The measured minimum and maximum FPS for the Medium preset show that frame pacing is consistent, with a tight range of 170-231 FPS at 1080p, which is reassuring for a smooth gaming experience.
