CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael, and built on a 5 nm process by TSMC. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU supports DDR5 memory in a dual-channel configuration, providing 83.2 GB/s of memory bandwidth. Its L3 cache is 32 MB shared, with 64 KB L1 and 1 MB L2 per core. The processor sits on the AMD Socket AM5 platform and uses PCIe Gen 5 with 24 lanes.

In Rust, a game known for its heavy procedural world generation and entity simulation, the CPU’s multi-threaded capabilities are important. The Ryzen 5 7400F scores 21,765 in Cinebench R23 multicore and 3,072 in single-core, placing it in the 83rd percentile among all CPUs. Its nearest rival, the Intel Core i5-14600T, scores 32,707 in average benchmark, a 0.1% difference, while the AMD Ryzen 7 PRO 6850H scores 32,812, which is 0.2% faster. These small deltas indicate that the 7400F is competitively positioned in raw compute.

The data from measured FPS suggests that the CPU is not the bottleneck at 1080p Low, where the system achieves 106 FPS. At this setting, the GPU is likely the limiting factor, as the CPU has ample single-thread performance to handle the game’s simulation ticks. However, at 4K Ultra, the average FPS drops to 19, which is far below what the CPU alone could produce, confirming that the GPU is the primary constraint. The CPU’s 12 threads help with Rust’s background tasks, such as world chunk loading and AI pathfinding, but the GTX 1660 Ti’s memory bandwidth and shading units become the wall at higher resolutions.

The CPU’s Passmark multi-thread score of 25,645 and single-thread score of 3,689 further illustrate its balance. In Rust, where frame times can spike during large base raids or when many players are nearby, the 7400F’s boost clock of 4.70 GHz helps maintain responsiveness. The data shows that at 1440p Medium, the average FPS is 49, with a minimum of 42 and maximum of 56, indicating that the CPU can keep up with the GPU’s output at this level, but the GPU is already starting to struggle.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is a Turing-architecture GPU built on a 12 nm process at TSMC, with 6,600 million transistors on a 284 mm² die. It has 1,536 shading units, 96 texture mapping units, and 48 raster output units. The base clock is 1500 MHz with a boost clock of 1770 MHz. Its memory configuration is 6 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s of bandwidth. The GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, and it has a TDP of 120 W with a dual-slot cooler and a single 8-pin power connector.

In Rust, the GPU’s role is critical at higher resolutions and settings. The GTX 1660 Ti has a percentile rank of 41 among all GPUs, with an average benchmark score of 7,723. Its nearest rival is the AMD Radeon 540, which is 0.7% faster, and the AMD Radeon Pro WX 3100 at 1.9% faster. This places the 1660 Ti in the mid-low tier of GPUs, which is reflected in the measured FPS data. At 1080p Low, the GPU produces 106 FPS average, which is excellent for a budget card. However, at 1080p Ultra, the average drops to 46 FPS, showing that the 6 GB VRAM and 288.0 GB/s bandwidth are insufficient for high-detail textures and effects.

The GPU’s memory bandwidth is a key limitation in Rust, which has large, streaming textures and a draw distance that can be extended. At 1440p Medium, the average FPS is 49, with a minimum of 42 and maximum of 56. The 6 GB VRAM may be fully utilized at this resolution, causing stutters or lower frame rates when loading new areas. At 4K, the situation worsens: 4K Medium averages 29 FPS, and 4K Low averages 43 FPS. This indicates that even at the lowest settings, the GPU cannot maintain playable frame rates at 4K, as the pixel count overwhelms the 84.96 GPixel/s pixel rate and 169.9 GTexel/s texture rate.

The GTX 1660 Ti’s FP32 performance is 5.437 TFLOPS, which is modest by modern standards but sufficient for Rust’s lighting and shadow calculations at lower presets. The Passmark G3D score of 12,871 and DirectX 11 score of 103 provide additional context: the GPU is optimized for older APIs, and Rust’s current build may not fully leverage its Turing features. The data shows that the GPU is the bottleneck in all measured configurations except possibly 1080p Low, where the CPU and GPU are more evenly matched.

How This Combo Ranks

The AMD Ryzen 5 7400F and GTX 1660 Ti combination ranks 2520th out of 2953 tested combos in Rust, placing it in the bottom 15% of systems. This low rank is primarily due to the GPU’s age and memory limitations, as the CPU is a modern part with strong benchmark scores. The combo’s rank is a reflection of the fact that Rust can be demanding on both CPU and GPU, but the GPU’s 6 GB VRAM and 288.0 GB/s bandwidth are insufficient for high-resolution play.

Compared to other combos, this pairing is best suited for 1080p gaming. At 1080p Low, it achieves 106 FPS, which is competitive for esports-style play. However, at 1080p Ultra, it drops to 46 FPS, which is below the 60 FPS threshold for smooth gameplay. The rank of 2520 indicates that most other tested combos can outperform this system at higher settings or resolutions, likely due to GPUs with more VRAM and higher memory bandwidth.

The CPU’s percentile rank of 83 is high, meaning it outperforms most CPUs in synthetic benchmarks, but the GPU’s percentile rank of 41 drags the overall combo down. The data shows that if paired with a stronger GPU, the Ryzen 5 7400F would likely rank much higher, as it has the compute headroom to support more demanding graphics cards. In Rust, the CPU’s role is to manage the game’s world state, and the 7400F does this well, but the GTX 1660 Ti cannot convert that CPU performance into high frame rates at 1440p or 4K.

Resolution Scaling

The measured FPS data shows a clear pattern of degradation as resolution increases. At 1080p Low, the average FPS is 106. Moving to 1440p Low, it drops to 73, a 31% decrease. At 4K Low, it drops further to 43, another 41% decrease from 1440p. This scaling is consistent with a GPU-bound scenario, where the number of pixels directly impacts the frame rate. The GTX 1660 Ti’s 6 GB VRAM is likely a limiting factor at 1440p and 4K, as Rust’s textures and draw distance require more memory than available.

At Medium settings, the scaling is similar: 71 FPS at 1080p, 49 FPS at 1440p (a 31% drop), and 29 FPS at 4K (a 41% drop from 1440p). The minimum FPS at 1440p Medium is 42, and at 4K Medium it is 25, indicating that frame pacing becomes inconsistent at higher resolutions. This suggests that the GPU is hitting its memory bandwidth limits, causing stutters in complex scenes.

At High settings, the average FPS is 60 at 1080p, 41 at 1440p, and 24 at 4K. The drop from 1080p to 1440p is 32%, and from 1440p to 4K is 41%. At Ultra settings, the average FPS is 46 at 1080p, 31 at 1440p, and 19 at 4K. The drop from 1080p to 1440p is 33%, and from 1440p to 4K is 39%. This consistent ~30-40% drop per resolution step confirms that the GPU is the limiting component, as the CPU’s performance does not scale with resolution.

The data indicates that this combo is only viable for 1080p gaming. At 1440p, even Low settings yield 73 FPS, which is playable, but Medium and above fall below 60 FPS. At 4K, no settings achieve a playable frame rate, with the highest average being 43 FPS at Low. This resolution scaling analysis points squarely at the GTX 1660 Ti as the bottleneck, as the Ryzen 5 7400F’s performance is not affected by resolution in the same way.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. With Low settings, the average FPS is 106, which is the highest in the entire dataset. Medium settings yield 71 FPS average, with a minimum of 60 and maximum of 82. High settings produce 60 FPS average, and Ultra settings drop to 46 FPS average. These numbers indicate that 1080p Low and Medium are the sweet spots for this system, providing smooth gameplay above 60 FPS. High settings are borderline, and Ultra is not recommended for consistent performance.

At 2560x1440, the performance drops significantly. Low settings average 73 FPS, which is still playable, but Medium drops to 49 FPS average, with a minimum of 42 and maximum of 56. High settings average 41 FPS, and Ultra averages 31 FPS. The 1440p resolution places a heavier load on the GPU’s memory subsystem, and the 6 GB VRAM is likely insufficient for Medium and above, leading to reduced frame rates. The data shows that only Low settings at 1440p are recommended for a playable experience.

At 3840x2160, the combo struggles. Low settings average 43 FPS, which is below the 60 FPS target. Medium settings average 29 FPS, with a minimum of 25 and maximum of 33. High settings average 24 FPS, and Ultra averages 19 FPS. The 4K resolution overwhelms the GTX 1660 Ti, and even Low settings are not smooth. The minimum FPS at 4K Medium is 25, indicating significant frame drops during intense scenes. This resolution is not viable for this combo in Rust.

The full breakdown shows a consistent trend: the system is capable at 1080p, marginal at 1440p with Low settings, and unsuitable for 4K. The measured FPS data aligns with the GPU’s benchmark scores, such as a Passmark G3D score of 12,871 and a 3DMark Steel Nomad score of 1,061, which are low compared to modern GPUs. The Ryzen 5 7400F, with its Cinebench R23 multicore score of 21,765, is not the limiting factor; instead, the GTX 1660 Ti’s 5.437 TFLOPS of FP32 performance and 288.0 GB/s bandwidth cap the frame rates. For a playable Rust experience, users should stick to 1080p with Low or Medium settings, as higher configurations result in sub-60 FPS averages.
