Rust

In Rust, the combination of the AMD Ryzen 7 9800X3D and the NVIDIA GeForce GTX 1660 Ti ranks 1488th out of 1717 tested combos, placing it in the bottom 13% of the database. This low standing is driven by the GPU's mid-range position, while the CPU sits in the 90th percentile of all CPUs. The measured frame rates confirm a GPU-bound configuration across all resolutions and settings.

How This Combo Ranks

The combo rank of 1488 out of 1717 means that only 229 tested combinations deliver lower performance in Rust. The CPU alone is a top-tier part: its average benchmark score of 37780 places it in the 90th percentile of all CPUs, and it sits within 0.1% of the Intel Xeon 6353P (37811) and Intel Core Ultra 5 225 (37831), and within 0.6–0.7% of the Intel Core i9-13900HK (38020) and Intel Core i5-13600KF (38028). The GPU, however, is far less dominant. Its average benchmark score of 13925 puts it in the 55th percentile of all GPUs, and it is only 0.4% above the AMD Radeon RX 570X (13871) and 0.7% below the NVIDIA Tesla K10 (14029). The combination of a 90th-percentile CPU with a 55th-percentile GPU produces a system that is heavily limited by the graphics card in Rust, a game that scales with both CPU and GPU load. The rank reflects this imbalance: the CPU's headroom is wasted at higher resolutions, where the GPU becomes the sole bottleneck.

GPU Role

The GTX 1660 Ti is built on the Turing architecture with a 12 nm process and features 6 GB of GDDR6 memory on a 192-bit bus, delivering 288.0 GB/s of bandwidth. Its base clock is 1500 MHz, boosting to 1770 MHz, while the memory runs at 1500 MHz (12 Gbps effective). The GPU has 1536 shading units, 96 texture mapping units, and 48 ROPs, with a pixel rate of 84.96 GPixel/s and a texture rate of 169.9 GTexel/s. FP32 performance is 5.437 TFLOPS. These specifications place the card in the lower-middle tier of the GPU landscape, and the benchmark data reflects that: a Passmark G3D score of 12871 and a 3DMark Steel Nomad DX12 score of 1061. In Rust, the GPU's 6 GB VRAM is sufficient for 1080p and 1440p at most settings, but at 4K Ultra the frame rate collapses to 17.6 FPS, indicating that the card's compute and memory bandwidth are insufficient for the game's highest demands. The GPU's average benchmark score of 13925 is 0.4% higher than the AMD Radeon RX 570X and 0.8% higher than the NVIDIA RTX A2000 Mobile (13821) and GeForce GTX 680 (13812), but 0.7% lower than the Tesla K10 (14029). This narrow spread shows that the GTX 1660 Ti is firmly in a performance band where small differences in architecture and clocks matter little in Rust's real-world frame rates.

Resolution Scaling

The measured FPS data shows a consistent drop as resolution increases, confirming that the GPU is the limiting component. At Low settings, the average FPS falls from 108 at 1080p to 76.4 at 1440p (a 29% reduction) and then to 45.3 at 4K (a 58% reduction from 1080p). At High settings, the drop is from 61.7 to 43.4 (30%) and then to 23.6 (62%). Medium settings go from 73.7 to 47.6 (35%) and then to 27.3 (63%). Ultra settings go from 45.2 to 30.8 (32%) and then to 17.6 (61%). The near-identical percentage drops across all settings indicate that the GPU's fill rate and memory bandwidth are the primary constraints; the CPU's strong single-thread and multi-thread performance does not compensate at higher resolutions. The scaling pattern also shows that 4K is not viable for this combo: even at Low settings, the 45.3 FPS average is below the 60 FPS threshold, and at Medium and above it falls below 30 FPS. The 1440p results are more playable, with Low and Medium exceeding 47 FPS, but Ultra drops to 30.8 FPS, which is borderline. At 1080p, the combo delivers smooth frame rates at Low (108 FPS) and Medium (73.7 FPS), but High (61.7) and Ultra (45.2) are still acceptable for many users.

Measured FPS Breakdown

The measured frame rates are as follows:

• 1920x1080: Low 108.0, Medium 73.7, High 61.7, Ultra 45.2
• 2560x1440: Low 76.4, Medium 47.6, High 43.4, Ultra 30.8
• 3840x2160: Low 45.3, Medium 27.3, High 23.6, Ultra 17.6

At 1080p, the gap between Low and Ultra is 62.8 FPS (108.0 vs 45.2), a 58% reduction. At 1440p, the gap is 45.6 FPS (76.4 vs 30.8), a 60% reduction. At 4K, the gap is 27.7 FPS (45.3 vs 17.6), a 61% reduction. This consistent relative drop suggests that the GPU's performance scales linearly with resolution, and that the CPU is not introducing any non-linear bottlenecks. The data also shows that the GTX 1660 Ti can maintain a 60+ FPS average only at 1080p Low, and a 30+ FPS average at 1440p Low and Medium, and at 4K Low. For a game like Rust, which often involves large player bases and complex world interactions, the CPU's 8 cores and 16 threads are more than sufficient, but the GPU's 6 GB VRAM and 288 GB/s bandwidth are the limiting factors at higher settings.

CPU Role

The AMD Ryzen 7 9800X3D is a desktop processor from the 9000 series, built on the Zen 5 architecture (Granite Ridge) using a 4 nm process. It has 8 cores and 16 threads, with a base clock of 4.70 GHz and a boost clock of 5.20 GHz. The L3 cache is 96 MB shared, and the CPU supports DDR5 memory with a dual-channel bus and 89.6 GB/s bandwidth. Its benchmark scores are strong: Cinebench R23 multi-core 34004, single-core 4800; Geekbench multi-core 18413, single-core 3341; Passmark multi-thread 40009, single-thread 4430. The CPU's average benchmark score of 37780 places it in the 90th percentile, and it is only 0.1% below the Intel Xeon 6353P and Intel Core Ultra 5 225, and 0.6–0.7% below the Intel Core i9-13900HK and i5-13600KF. In Rust, the CPU's high single-thread performance and large L3 cache are beneficial for the game's simulation and world-streaming tasks. However, the measured FPS data shows that the CPU is not the limiting factor: at 1080p Low, the combo reaches 108 FPS, which is well below the CPU's potential, and the frame rate drops sharply with resolution, indicating that the GPU is the bottleneck. The CPU's 96 MB L3 cache is particularly useful for Rust's large world data, but the GTX 1660 Ti's 6 GB VRAM and 288 GB/s bandwidth cannot keep up with the CPU's ability to feed frames. The launch MSRP of the CPU is $479, and the GPU's launch MSRP is 279 USD, but the performance data shows that the GPU's mid-range position is the primary reason this combo ranks so low in Rust.
