Rust

The AMD Ryzen 9 9900X and NVIDIA GeForce GTX 1660 Ti pairing in Rust presents a study in asymmetry. The CPU is a 12-core Zen 5 flagship-class part, while the GPU is a Turing-based card from the previous decade. The benchmark data shows a system where the graphics card consistently dictates playable framerates, leaving the processor largely underutilized across all tested settings and resolutions.

FAQ

Q: What is the overall performance rank of this CPU and GPU combination in Rust?

A: The combo ranks 1478 out of 1717 tested combinations in the database, placing it in the bottom percentile of systems for this specific title.

Q: Is the GTX 1660 Ti capable of achieving 60 FPS at 1920x1080 in Rust?

A: Yes, but only at Low settings, where the average framerate is 106.3 FPS. At Medium settings it drops to 72.9 FPS, and at High settings it falls to 59.1 FPS, which is just below the 60 FPS threshold.

Q: How does the Ryzen 9 9900X compare to its nearest rival, the Ryzen 9 9900X3D?

A: The Ryzen 9 9900X has an average benchmark score of 54450, which is 0.4% lower than the Ryzen 9 9900X3D's average score of 54681. The performance delta between the two is negligible.

Q: What is the maximum average framerate achievable with this setup at 2560x1440 resolution?

A: The highest average framerate at 2560x1440 is 74 FPS, which is achieved only when the graphics settings are set to Low. Moving to Medium settings reduces the average to 48.9 FPS.

Q: What is the GPU's percentile ranking among all tested graphics cards?

A: The GeForce GTX 1660 Ti sits in the 55th percentile of all GPUs, indicating it is a mid-range performer. Its average benchmark score is 13925.

Q: Does the CPU show any signs of bottlenecking at 3840x2160 resolution?

A: At 4K with Ultra settings, the average framerate is just 19.5 FPS. This is a GPU-bound scenario where the graphics card's 6 GB VRAM and 288.0 GB/s bandwidth are saturated, so the CPU's performance is not a limiting factor.

How This Combo Ranks

The data places this combination at rank 1478 out of 1717 combos in Rust, a position that reflects a significant performance deficit relative to the broader test pool. This is a low ranking, situating the pairing in the bottom 14% of all tested systems. The primary cause is the GPU, which ranks in the 55th percentile against all other graphics cards, while the CPU ranks in the 94th percentile against all other processors. The gap between these two percentile scores illustrates that the graphics card is the bottleneck in this configuration.

Benchmark results show that the GPU's average score of 13925 places it in a tight cluster with its nearest rivals. It is 0.4% ahead of the AMD Radeon RX 570X and 0.8% ahead of both the NVIDIA RTX A2000 Mobile and the GeForce GTX 680. It trails the NVIDIA Tesla K10 by 0.7%. These small deltaPct values indicate that the GTX 1660 Ti is squarely in a specific performance tier, and any of these cards would produce similar framerates in Rust. The CPU, conversely, is a top-tier part. Its 54450 average score is only 0.4% behind the Ryzen 9 9900X3D and 1.5% behind the Intel Core Ultra 5 245K, showing that it is not the component holding the system back.

CPU Role

The Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It operates on a base clock of 4.40 GHz and can boost up to 5.60 GHz, with a 120 W TDP. The CPU also features 64 MB of shared L3 cache and supports DDR5 memory over a dual-channel bus, which provides a memory bandwidth of 89.6 GB/s. The benchmark data shows strong multi-threaded performance, including a Cinebench R23 multicore score of 46438 and a Geekbench multicore score of 19827.

In Rust, however, this processing power is not the deciding factor. The measured framerates show that the GPU is the limiting component across all settings. For instance, at 1920x1080, the framerate scales from 106.3 FPS at Low settings down to 48.8 FPS at Ultra settings, a direct result of increased GPU load. The CPU's role is to feed the GPU, and with its 12 cores, it has ample headroom to do so. The data suggests that the CPU is not a bottleneck, as framerate drops are entirely correlated with graphics settings and resolution increases, which are GPU-centric workloads. The CPU’s high single-thread performance, evidenced by its Cinebench R23 single-core score of 6555, is more than sufficient for Rust's game logic, but it cannot compensate for the GPU's limitations in rendering the scene.

Measured FPS Breakdown

The measured FPS data shows a clear and consistent pattern where the GTX 1660 Ti dictates performance. At 1920x1080, the lowest tested resolution, the system achieves an average of 106.3 FPS at Low settings. This is the only setting that delivers a clearly comfortable framerate. At Medium settings, the average drops to 72.9 FPS. High settings yield 59.1 FPS, and Ultra settings pull the average down to 48.8 FPS. This progression highlights how quickly the GPU becomes the limiting factor as graphical fidelity increases.

Moving to 2560x1440, the framerates fall further. The Low setting average is 74 FPS, which is still playable but a significant drop from the 1080p result. Medium settings average 48.9 FPS, High settings average 43.5 FPS, and Ultra settings drop to 32.9 FPS. The scaling between Low and Ultra at this resolution is substantial, showing a 41.1 FPS difference. At 3840x2160, the GPU is overwhelmed. The Low setting average is 44.6 FPS, Medium is 29.9 FPS, High is 22.8 FPS, and Ultra is 19.5 FPS. None of these 4K framerates are ideal for a smooth experience, and the Ultra result indicates that the card is at its absolute limit. The data shows that the GTX 1660 Ti is only suitable for high-refresh-rate gaming at 1080p with reduced settings, or for playable framerates at 1440p with Low settings.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture using the TU116 chip, fabricated on a 12 nm process. It has 6 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 288.0 GB/s. The GPU has a base clock of 1500 MHz and a boost clock of 1770 MHz. Its compute capabilities are modest, with a FP32 performance of 5.437 TFLOPS. The card's 1536 shading units and 48 ROPs are reflected in its benchmark scores, such as a 3DMark Steel Nomad score of 1061 and a Passmark G3D score of 12871.

In Rust, the GPU's role is to render the game world, and its capabilities are the primary constraint. The measured FPS data shows that the card's performance ceiling is low. The difference between 1080p Low and 1080p Ultra is 57.5 FPS, which is a massive performance hit for higher visual quality. This indicates that the GPU's pixel throughput and memory bandwidth are quickly saturated by the game's rendering demands. The 6 GB VRAM is also likely a limitation at higher resolutions and settings, as the texture data required for Ultra settings can exceed this capacity. The GPU's percentile ranking of 55 places it in the middle of the pack, and its average score of 13925 is less than 1% different from its nearest rivals, confirming that it is a baseline mid-range part. In this configuration, the GPU is the definitive bottleneck, and its performance characteristics, not the CPU's, determine the playability of Rust.
