Rust

Rust with the Intel Core i9-14900K and NVIDIA GeForce GTX 1660 SUPER presents a classic bottleneck scenario. The data shows a processor with top-tier synthetic scores paired with a graphics card that lands in the 53rd percentile of all GPUs. The measured frame rates across resolutions and settings confirm that the GTX 1660 SUPER is the primary constraint in this pairing, especially as resolution climbs. This analysis breaks down the measured FPS data to show exactly where this combination excels and where it falls short.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, which points directly at the GPU as the limiting factor. At Low settings, the average frame rate falls from 106 FPS at 1920x1080 to 73 FPS at 2560x1440, a reduction of 33 FPS. Moving to 3840x2160 at Low, the average drops further to 43 FPS. This scaling pattern—roughly a 30% loss from 1080p to 1440p and another 40% loss from 1440p to 4K—is typical of a GPU that is running out of pixel throughput. The CPU, with its 24 cores and 32 threads, is not the constraint here; it has ample headroom to feed frames at lower resolutions.

The gap between Low and Ultra settings widens as resolution increases, which is another sign of GPU-bound performance. At 1920x1080, the difference between Low (106 FPS) and Ultra (46 FPS) is 60 FPS. At 2560x1440, that spread is 42 FPS (73 vs. 31). At 3840x2160, the spread narrows to 24 FPS (43 vs. 19). When the GPU is overwhelmed at 4K, even dropping to Low settings cannot recover playable frame rates, because the raw pixel count is the bottleneck. The 1080p results show the best scaling potential—dropping from Ultra to Low nearly doubles the frame rate, indicating that the game engine can utilize the CPU's power when the GPU is less stressed.

The 4K data tells a clear story: this combination is not viable for 4K gaming at any preset. The highest average at 3840x2160 is 43 FPS on Low, which is below the 60 FPS threshold most players target for smooth gameplay. The Medium preset at 4K produces a 29 FPS average with a minimum of 25 FPS, which would be noticeable stutter. The Ultra preset at 4K drops to a 19 FPS average, which is effectively unplayable. The resolution scaling data suggests that 1080p is the sweet spot for this pairing, with 1440p being a compromise for those willing to lower settings significantly.

GPU Role

The GTX 1660 SUPER is built on the Turing architecture with a 12 nm process node from TSMC. Its 6 GB of GDDR6 memory on a 192-bit bus provides 336.0 GB/s of bandwidth, which is adequate for 1080p gaming but becomes a limiting factor at higher resolutions. The memory clock runs at 1750 MHz with 14 Gbps effective speed. The GPU's base clock is 1530 MHz, boosting to 1785 MHz under load. These clocks, combined with 1408 shading units, deliver 5.027 TFLOPS of FP32 performance. The pixel rate is 85.68 GPixel/s, and the texture rate is 157.1 GTexel/s.

In Rust, the 6 GB VRAM capacity is a concern at higher settings and resolutions. The data shows that at 1080p, the GPU can handle Ultra settings at 46 FPS average, but the frame rate is likely constrained by memory bandwidth and fill rate rather than raw compute. The 4K results, where even Low settings only reach 43 FPS, suggest that the 6 GB frame buffer is being saturated. The GTX 1660 SUPER sits at the 53rd percentile of all GPUs, with an average benchmark score of 12986. Its nearest rival, the NVIDIA GeForce RTX 3050 Ti Mobile, scores 12940, a 0.4% difference. The AMD Radeon RX 580 is essentially tied at 12928, also 0.4% ahead. This places the GTX 1660 SUPER in the mid-range tier, which aligns with the measured Rust performance.

The GPU's DirectX 12 benchmark score of 50 (Passmark) and DirectX 11 score of 104 indicate that it handles older APIs better than newer ones. Rust, being a survival game with a focus on CPU-bound simulation, may not fully utilize the GPU's capabilities. However, the frame rate data shows that the GPU is still the limiting factor at 4K. At 1080p Low, the 106 FPS average suggests the CPU is capable of pushing higher frame rates, but the GPU cannot sustain them at higher settings. The boost clock of 1785 MHz is modest by modern standards, but it is consistent with the card's mid-range positioning.

CPU Role

The Intel Core i9-14900K is a desktop processor from the Core 14th Gen series, based on the Raptor Lake architecture. It has 24 cores and 32 threads, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. The processor is built on Intel's 10 nm process node with a die size of 257 mm². Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. It supports both DDR4 and DDR5 memory in a dual-channel configuration, with ECC memory support available. The PCIe interface is Gen 5 with 16 lanes for the CPU.

The CPU's benchmark results are exceptional. In Cinebench R23, it scores 39399.5 in multi-core and 2262.5 in single-core. Geekbench scores are 21697 multi-core and 2655 single-core. Passmark shows a multithread score of 58674 and a single-thread score of 4697. These numbers place the i9-14900K at the 95th percentile of all CPUs, with an average benchmark score of 79097. Its nearest rivals include the Intel Core i9-14900KF at 79371 (-0.3% delta), the Intel Core Ultra 9 290HX Plus at 79574 (-0.6% delta), and the AMD EPYC 7413 at 80041 (-1.2% delta). The AMD Ryzen AI Max+ 395 trails at 77740, which is 1.7% behind.

In Rust, the CPU's role is evident in the 1080p Low setting results. The 106 FPS average at 1920x1080 Low indicates that the CPU can deliver high frame rates when the GPU is not the bottleneck. The boost clock of 6.00 GHz is particularly valuable for single-threaded game logic, which Rust relies on heavily. The 36 MB of L3 cache helps with the game's world simulation and entity management. The data suggests that the CPU is not the limiting factor at any resolution in this pairing—even at 4K Ultra, the 19 FPS average is far below what the CPU could generate. The bottleneck is unambiguously the GPU.

The combo rank in game is 3188 out of 3723 combinations, which places this pairing in the lower 15% of tested configurations. This rank reflects the GPU's limitations rather than the CPU's capabilities. The i9-14900K is overkill for a GTX 1660 SUPER in most scenarios, but it provides headroom for future GPU upgrades. The measured data shows that the CPU maintains consistent frame rates across settings at 1080p, with the GPU dictating the final numbers.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression from Low to Ultra. Low settings deliver an average of 106 FPS, which is the highest recorded for this combination. Medium settings drop to 71 FPS average, with a minimum of 60 FPS and a maximum of 82 FPS. High settings produce 60 FPS average, exactly hitting the 60 FPS target. Ultra settings fall to 46 FPS average. The step from Low to Medium is a 35 FPS drop, which is significant. The step from Medium to High is 11 FPS, and from High to Ultra is 14 FPS. This pattern suggests that the Low preset is the most playable at 1080p, with Medium being borderline acceptable.

At 2560x1440, the frame rates drop across all settings. Low settings average 73 FPS, which is still playable. Medium settings average 49 FPS, with a minimum of 42 FPS and a maximum of 56 FPS. High settings average 41 FPS, and Ultra settings average 31 FPS. The drop from 1080p to 1440p is substantial: Low goes from 106 to 73 FPS (-33), Medium from 71 to 49 FPS (-22), High from 60 to 41 FPS (-19), and Ultra from 46 to 31 FPS (-15). The relative performance gap between Low and Ultra narrows at 1440p compared to 1080p, indicating the GPU is becoming the limiting factor.

At 3840x2160, the results are poor across the board. Low settings average 43 FPS, Medium averages 29 FPS with a minimum of 25 FPS and a maximum of 33 FPS, High averages 24 FPS, and Ultra averages 19 FPS. The difference between Low and Ultra at 4K is only 24 FPS, showing that settings adjustments have diminishing returns at this resolution. The minimum FPS of 25 on Medium at 4K highlights the stuttering that would occur during gameplay. None of the 4K presets reach a playable 60 FPS average, and even 30 FPS is only achievable on Low settings.

The Medium preset is the only one with min/max data for all three resolutions. At 1080p Medium, the range is 60-82 FPS. At 1440p Medium, it is 42-56 FPS. At 4K Medium, it is 25-33 FPS. This data provides a useful window into frame time consistency. The 4K Medium range of 8 FPS is tight but at a low absolute level, suggesting the GPU is hitting a hard limit. The 1080p Medium range of 22 FPS indicates more variability, likely from CPU-driven scenes. Overall, the measured FPS breakdown confirms that 1080p is the only resolution where this pairing delivers consistently playable frame rates across multiple presets.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this pairing depend on the target resolution and frame rate. At 1920x1080, the Low preset delivers the best experience with a 106 FPS average, which is well above the 60 FPS target. If visual quality is a priority, the High preset still achieves a 60 FPS average, making it a viable choice for players who want a balance of performance and fidelity. The Medium preset at 71 FPS is also acceptable, but the step from Low to Medium incurs a 35 FPS penalty, which may not be worth the visual gain for competitive play.

At 2560x1440, the Low preset is the only one that maintains a comfortable frame rate at 73 FPS. The Medium preset at 49 FPS is playable but may feel less smooth, especially in fast-paced combat. The High preset at 41 FPS and Ultra at 31 FPS are below the 60 FPS threshold and would likely result in a suboptimal experience. For 1440p users, Low settings are recommended to maintain responsiveness. The data shows that the GPU's 6 GB VRAM and 336.0 GB/s bandwidth cannot handle higher presets at this resolution without significant frame rate drops.

At 3840x2160, no settings are recommended for a smooth experience. The Low preset at 43 FPS is the best option if 4K is mandatory, but it will still feel sluggish. The Medium preset at 29 FPS and below is not worth considering for gameplay. The data strongly suggests that players should avoid 4K with this combination. The i9-14900K's 6.00 GHz boost clock and 24 cores provide ample CPU headroom, but the GTX 1660 SUPER's 5.027 TFLOPS of FP32 performance and 6 GB memory are simply insufficient for 4K Rust.

For the best overall experience, the 1080p Low preset is the clear winner. It maximizes frame rate at 106 FPS, which gives headroom for frame time spikes during busy scenes. The High preset at 60 FPS is a reasonable alternative for those who value visual quality over raw performance. The Medium preset at 71 FPS offers a middle ground, but the data shows diminishing returns beyond Low. The Ultra preset should be avoided—at 46 FPS, it is below the 60 FPS target and offers marginal visual improvements over High. The settings recommendations are straightforward: prioritize 1080p, use Low for competitive play, and reserve High for a more visually rich experience.
