Rust

The AMD Ryzen 7 5800XT and NVIDIA GeForce GTX 1660 SUPER pairing in Rust presents a clear case of a modern, high-core-count CPU paired with a now-end-of-life GPU. The benchmark data shows a combination that is heavily constrained by the graphics card at higher resolutions, yet capable of delivering smooth performance at 1080p with the right settings. This analysis breaks down the measured FPS across resolutions and presets, contextualizes the combo's rank, and offers practical advice for tuning the game.

Resolution Scaling

The measured FPS data reveals a dramatic and consistent drop as resolution increases, which is the signature of a GPU-bound scenario. At 1080p with Low settings, the combo achieves 108.3 FPS, but this falls to 75.4 FPS at 1440p and further down to 43.1 FPS at 4K. This represents a 30.4% drop from 1080p to 1440p and a 60.2% drop from 1080p to 4K at the same settings. The pattern is similar across all presets, with the High preset dropping from 62.8 FPS at 1080p to 42.3 FPS at 1440p and 23.2 FPS at 4K.

The scaling factor is telling. The GTX 1660 SUPER has 6 GB of GDDR6 memory on a 192-bit bus with 336.0 GB/s bandwidth. This is simply insufficient for the pixel throughput demanded by 4K. The data shows that even at Low settings, 4K performance is only 43.1 FPS, which is below the threshold for a consistently smooth experience in a fast-paced survival game. The GPU is clearly the limiting component here. The Ryzen 7 5800XT, with its 8 cores and 16 threads, is not the bottleneck; its high single-thread performance, evidenced by a 3dmark_single_thread score of 959, is more than adequate for Rust's simulation-heavy gameplay.

How This Combo Ranks

In the comprehensive database of tested combinations, this specific pairing ranks 1482 out of 1717 combos. This places it in the lower 13.7% of all tested systems for Rust, a reflection of the GPU's age rather than any deficiency in the CPU. The GPU's percentile rank against all GPUs is 55, meaning it is roughly average, but its nearest rivals are all integrated or low-end discrete solutions. The AMD Radeon RX Vega 11, Intel Iris Xe MAX Graphics, and AMD Radeon Vega 11 all have average scores within 0.5% of the GTX 1660 SUPER. This indicates that the GPU, while not bottom-tier, is firmly in the entry-level class for modern gaming.

The CPU, in contrast, is a powerhouse. It sits in the 86th percentile against all CPUs, with an average benchmark score of 29774. Its nearest rivals are all other strong 8-core parts, such as the AMD Ryzen 7 PRO 5755GE and the AMD Ryzen 7 7840H, with deltaPct values of 0.1% and -0.3% respectively. This massive disparity between the CPU's high rank and the combo's low rank confirms that the GTX 1660 SUPER is holding back the Ryzen 7 5800XT. The data suggests that this combo is not balanced for 1440p or 4K, but the CPU has significant headroom for future GPU upgrades.

Settings Recommendations

The measured data provides clear guidance for the best experience. At 1080p, the Low preset delivers 108.3 FPS, which is excellent for competitive play and high-refresh monitors. The Medium preset still provides a very playable 74 FPS, offering a significant visual upgrade over Low with only a 31.7% performance hit. The High preset at 62.8 FPS is playable, but the jump to Ultra costs a further 25.3% performance, bringing it down to 46.9 FPS. For the best balance of visual fidelity and frame rate at 1080p, the Medium preset is the recommended choice, as it stays well above the 60 FPS mark.

At 1440p, the situation changes. The Low preset is the only one that remains comfortably playable at 75.4 FPS. The Medium preset drops to 47.2 FPS, and High falls to 42.3 FPS. Ultra is not a viable option at 28.6 FPS. For 1440p gaming, sticking to Low settings is the only way to ensure a smooth experience. At 4K, the results are universally poor. Even the Low preset only manages 43.1 FPS, and the High preset falls to 23.2 FPS. The data clearly shows that this game, with this GPU, should be played at 1080p.

Measured FPS Breakdown

The complete measured FPS data is presented below for reference.

At 1920x1080:

• Low: 108.3 FPS average
• Medium: 74 FPS average
• High: 62.8 FPS average
• Ultra: 46.9 FPS average

At 2560x1440:

• Low: 75.4 FPS average
• Medium: 47.2 FPS average
• High: 42.3 FPS average
• Ultra: 28.6 FPS average

At 3840x2160:

• Low: 43.1 FPS average
• Medium: 29.9 FPS average
• High: 23.2 FPS average
• Ultra: 20.6 FPS average

The pattern is consistent: each resolution step down from 1080p results in a roughly 30-40% reduction in FPS across all settings. The delta between Low and Ultra within a single resolution is also substantial, with Ultra generally performing at about 43% of the Low preset's frame rate. This highlights the significant GPU workload increase from the higher quality presets.

FAQ

Q: Can this combo run Rust at 4K?

A: The data shows that 4K performance is insufficient for a smooth experience. At Low settings, the average FPS is 43.1, which drops to 20.6 FPS at Ultra. None of the measured presets achieve a consistent 60 FPS at this resolution.

Q: What is the best resolution for this system?

A: The measured FPS data indicates that 1920x1080 is the only resolution where the combo can deliver high frame rates. At 1080p, the Low and Medium presets achieve 108.3 and 74 FPS respectively, which are both well above the playable threshold.

Q: Is the CPU or GPU the bottleneck in Rust?

A: The benchmark data suggests the GPU is the limiting factor. The Ryzen 7 5800XT ranks in the 86th percentile of all CPUs, while the GTX 1660 SUPER only ranks in the 55th percentile. The significant FPS drops at higher resolutions are characteristic of GPU limitation.

Q: How does the GTX 1660 SUPER compare to its closest rivals?

A: The GPU's average benchmark score is 14286. Its nearest rivals, such as the AMD Radeon RX Vega 11 and Intel Iris Xe MAX Graphics, have average scores within 0.5% of this figure, indicating they are all in the same performance class.

Q: Should I use the Ultra preset for the best visuals?

A: The data shows that the Ultra preset severely impacts performance. At 1080p, it drops to 46.9 FPS, and at 1440p, it falls to 28.6 FPS. The visual quality gain is not worth the substantial frame rate loss.

Q: Will lowering the settings from High to Low improve the frame rate?

A: Yes, the data shows a significant improvement. At 1080p, moving from High to Low increases the average FPS from 62.8 to 108.3, a 72.5% improvement. At 1440p, the same change increases FPS from 42.3 to 75.4.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 (Vermeer) architecture processor with 8 cores and 16 threads. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 32 MB L3 cache. The CPU's benchmark scores are exceptionally strong. Its Cinebench R23 multicore score of 23794 and single-core score of 3359 place it in the top tier of processors. The Passmark multithread score of 27988 and the single-thread score of 3538 further confirm its capability.

In Rust, which is known for its heavy server-side and simulation logic, the CPU's strong single-thread performance is critical. The 3dmark_2_threads score of 1879 and the 3dmark_4_threads score of 3603 show that the CPU scales well with the limited thread counts that many game engines utilize. The high clocks and large cache ensure that the CPU can process the game's world simulation without becoming a bottleneck.

However, this CPU's power is largely untapped in this specific pairing. The data shows that it is not the limiting factor at any resolution, as the FPS scales consistently with resolution changes, a classic GPU-bound signature. The CPU's performance headroom means that a future GPU upgrade would yield substantial FPS gains without needing to replace the processor. The data indicates that this combo's low rank of 1482 out of 1717 is directly attributable to the GPU, not the CPU.
