Rust

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce GTX 1660 Ti presents a specific performance profile in Rust, one defined by the GPU's limitations at higher resolutions and the CPU's capacity to drive high frame rates at 1080p. The measured data reveals a system that is well-balanced for competitive settings at 1920x1080, but one that struggles to maintain playable frame rates at 4K. This analysis breaks down the benchmark results, focusing on the scaling of performance across resolution and settings to provide a clear picture of what this combo can deliver.

Resolution Scaling

The most significant finding in the data is the steep decline in average frame rates as resolution increases from 1920x1080 to 3840x2160. At the "Low" preset, the average FPS drops from 106 at 1080p to 73 at 1440p, a reduction of 33 FPS. The trend continues at 4K, where the "Low" preset delivers an average of 43 FPS. This represents a 63 FPS difference between 1080p and 4K, a 59.4% drop from the 1080p figure. This scaling pattern is typical of a system where the GPU becomes the primary bottleneck at higher resolutions.

The data indicates that the GTX 1660 Ti, with its 6 GB of GDDR6 memory and 288.0 GB/s bandwidth, is the limiting component when resolution demands more pixel processing. At 1080p, the workload is lighter, allowing the CPU to push frame rates much higher. However, as the pixel count quadruples from 1080p to 4K, the GPU's fill rate and memory bandwidth are saturated, causing the average FPS to plummet. The shift from 1440p to 4K shows a further significant drop, with the "High" preset falling from 41 FPS to 24 FPS, and the "Ultra" preset falling from 31 FPS to 19 FPS, highlighting the intense pressure on the GPU at 4K.

The data strongly suggests that this combination is not suited for 4K gaming in Rust. Even at the lowest settings, the average of 43 FPS is below the 60 FPS target many players consider smooth. The performance at 4K is only viable for a slideshow-like experience, not a competitive or immersive one. The GPU's 41st percentile ranking among all GPUs, based on average benchmark scores, further supports this, indicating it is a mid-to-low-tier performer that struggles with the demands of 4K in modern titles.

Settings Recommendations

Given the measured data, the optimal experience for this combo is found at 1920x1080. The "Low" preset delivers an average of 106 FPS, which is excellent for a fast-paced survival game where responsiveness is key. This setting provides the highest headroom for frame rate, ensuring smooth gameplay even in complex scenes with many players or structures. The "Medium" preset is also strong, with an average of 71 FPS and a minimum of 60 FPS, which is a good balance between visual fidelity and performance.

Moving up to the "High" preset at 1080p still yields a respectable 60 FPS average, but the "Ultra" preset drops to 46 FPS, which is noticeably less smooth and may introduce stutter in demanding situations. For players prioritizing competitive advantage and consistent frame rates, the "Low" preset is the clear recommendation, as it offers the highest average FPS. The "Medium" preset is a solid alternative for those who want a visual upgrade without sacrificing too much fluidity, as its minimum FPS of 60 is still a solid baseline.

At 2560x1440, the data shows a significant performance hit. The "Low" preset is the only one that approaches a playable state, with an average of 73 FPS. The "Medium" preset averages 49 FPS, and the "High" and "Ultra" presets fall to 41 and 31 FPS respectively. This suggests that 1440p is only viable on the lowest settings, and even then, the frame rate is less stable than at 1080p. The data indicates that for the best experience, users should stick to 1080p and adjust the preset from "Low" to "Medium" based on their preference for smoothness over visual detail.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz. Its performance in synthetic benchmarks is strong, with a Cinebench R23 multicore score of 20851 and a single-core score of 2943. This processing power is reflected in the game's performance at lower resolutions, where the CPU is not the primary bottleneck.

The data shows that at 1920x1080, the system is capable of delivering over 100 FPS on the "Low" preset. This high frame rate is a direct result of the CPU's strong single-thread performance and its ability to feed the GPU with enough data. The CPU's 12 threads are also beneficial for Rust, which is known to utilize multiple cores for physics, AI, and world simulation. The Ryzen 5 8400F's 16 MB of shared L3 cache and support for DDR5 memory further help in this regard, reducing latency and improving data throughput.

Compared to its nearest rivals, the Ryzen 5 8400F's average benchmark score of 25005 is nearly identical to the AMD Ryzen 5 7500F, which has an average score of 24964 and a deltaPct of 0.2. This indicates that the two CPUs are effectively tied in overall performance. The 8400F's performance is also very close to that of the Intel Core i7-13620H, which has an average score of 24911 and a deltaPct of 0.4. The data suggests that the CPU is more than capable of handling Rust at 1080p, and its role becomes less critical as resolution increases and the GPU takes over the workload.

How This Combo Ranks

In the database of tested hardware combinations for Rust, this specific pairing of the AMD Ryzen 5 8400F and NVIDIA GeForce GTX 1660 Ti holds a combo rank of 3188 out of 3723 possible combinations. This places it in the bottom 14.3% of all tested systems, indicating that it is a lower-performing combination for this particular game. This ranking is a direct consequence of the GTX 1660 Ti's limitations, which is the primary factor holding back performance in Rust.

The GPU's percentile ranking of 41 among all GPUs is a clear indicator of its relative performance level. This is further highlighted by its nearest rivals, which include the AMD Radeon 540 (avg score 7673, deltaPct 0.7) and the Intel Arc A310 (avg score 7550, deltaPct 2.3). These are all entry-level or low-end graphics cards, and the GTX 1660 Ti's average benchmark score of 7723 is only marginally higher. This demonstrates that while the CPU is a solid mid-range performer, the GPU is a limiting factor that drags down the overall combo ranking.

The high combo rank number (3188) suggests that a vast majority of other CPU-GPU pairings tested will outperform this one in Rust. This is not a combination designed for high-end gaming or high refresh rate monitors at 1440p or 4K. Instead, it is a system that can deliver a playable experience at 1080p, provided the settings are managed appropriately. The data shows that the CPU's potential is largely untapped due to the GPU's inability to keep up at higher resolutions.

At 1440p, the average FPS drops below 73 on all presets, and at 4K, it falls below 43, making only the "Low" preset remotely playable. The difference between the "Low" and "Ultra" presets is also consistent, with "Ultra" averaging roughly half the FPS of "Low" at any given resolution.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is a Turing-architecture GPU built on a 12 nm process. It has 1536 shading units, 96 texture mapping units, and 48 raster output units. Its boost clock is rated at 1770 MHz, and it has 6 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 288.0 GB/s. These specifications place it as a solid 1080p graphics card, but its performance in Rust at higher resolutions is clearly limited.

The data shows that the GPU is the definitive bottleneck at 1440p and 4K. The frame rate drops are not gradual; they are steep, indicating that the GPU's pixel processing capabilities are being overwhelmed. The 6 GB of VRAM may also be a limiting factor in Rust, which can be memory-intensive with large worlds and many assets. At 4K with "Ultra" settings, the average FPS is 19, which is unplayable. Even at 1440p on "High", the average FPS is only 41, which is just at the edge of playability for some.

The GPU's overall performance percentile is 41, meaning it performs better than 41% of all GPUs in the database. Its average benchmark score is 7723, which is very close to its nearest rivals, such as the AMD Radeon 540 (avg score 7673) and the AMD Radeon Pro WX 3100 (avg score 7580). This places the GTX 1660 Ti in the lower-mid tier of graphics cards. In the context of Rust, this means it can handle the game at 1080p with reduced settings, but it lacks the raw power and memory bandwidth for higher resolutions. The GPU's role is to provide a playable experience at 1080p, and the benchmark data confirms that it fulfills this role, but nothing more.
