Rust

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 2060 is a lopsided combination in Rust: the 12-core Zen 5 processor is a top-tier part, while the RTX 2060 is an older Turing GPU with 6 GB of VRAM. The measured results show a clear pattern where the GPU becomes the limiting factor as resolution and settings increase, yet the CPU’s strength keeps low-setting frame rates very high. Below is a breakdown of how this pairing behaves across resolutions and settings, using only the provided data.

FAQ

Q: What is the best resolution for this combo in Rust?

A: At 1920x1080, the combo achieves playable frame rates on all settings, with Low hitting 126 avg FPS and High reaching 71 avg FPS. At 2560x1440, only Low (86 avg FPS) and Medium (58 avg FPS) remain smooth, while 3840x2160 drops below 60 FPS even on Low (51 avg FPS).

Q: How does the RTX 2060’s 6 GB VRAM affect Rust?

A: The 6 GB GDDR6 memory with 336.0 GB/s bandwidth is a hard limit at higher settings. At 3840x2160 Ultra, the combo only manages 22 avg FPS, and at 2560x1440 Ultra it falls to 37 avg FPS. The data suggests that Ultra presets at 1440p or above exceed what the VRAM and GPU compute can handle.

Q: Is the Ryzen 9 9900X3D bottlenecking the RTX 2060?

A: No. The CPU’s benchmarks are far ahead of the GPU’s. For example, the CPU scores 47737 in Cinebench R23 multicore and 6739 in single-core, while the GPU’s PassMark G3D score is 14111. In Rust, the FPS drops from 126 at 1080p Low to 51 at 4K Low, indicating the GPU is the primary limiter as resolution climbs.

Q: What settings preset delivers the best balance of visuals and performance?

A: At 1080p, Medium (84 avg FPS) offers a solid middle ground with min FPS of 72. At 1440p, Low (86 avg FPS) is the only preset above 60 FPS, while Medium (58 avg FPS) is borderline. For 4K, Low (51 avg FPS) is the only preset above 50 FPS.

Q: How does this combo rank against other tested configurations?

A: The combo ranks 2303 out of 2953 tested combos in Rust, placing it in the lower half (about 22nd percentile). This is consistent with the GPU being a mid-range part (58th percentile among all GPUs) paired with a high-end CPU (91st percentile among all CPUs).

Q: Does the CPU’s 128 MB L3 cache help in Rust?

A: The CPU has 128 MB of L3 cache, which is beneficial for CPU-bound scenarios. However, the measured FPS data shows that even with this cache, the combo cannot maintain high frame rates at 4K Ultra (22 avg FPS), proving the GPU is the bottleneck in GPU-heavy settings.

GPU Role

The NVIDIA GeForce RTX 2060 is built on the Turing architecture with 1920 shading units, 120 TMUs, and 48 ROPs. Its base clock is 1365 MHz and boost clock is 1680 MHz, with memory running at 1750 MHz (14 Gbps effective) across a 192-bit bus, yielding 336.0 GB/s bandwidth. The 6 GB GDDR6 frame buffer is the most critical spec here.

In Rust, the GPU’s role becomes evident when comparing FPS across settings at a fixed resolution. At 1920x1080, the average FPS drops from 126 on Low to 84 on Medium, then 71 on High, and finally 54 on Ultra. That is a 57% reduction from Low to Ultra. At 2560x1440, the same progression goes from 86 (Low) to 58 (Medium) to 49 (High) to 37 (Ultra), a 57% drop. At 3840x2160, Low yields 51 FPS, Medium 34, High 29, and Ultra 22, a 57% drop as well. This consistent pattern across resolutions shows that the GPU’s shading and memory throughput scale linearly with settings, and the 6 GB VRAM is likely exhausted at Ultra on 1440p and above.

The RTX 2060’s PassMark G3D score of 14111 places it at the 58th percentile among all GPUs. Its nearest rivals in the benchmark database include the NVIDIA GeForce GTX 580 (score 15283, delta 0%), AMD Radeon 680M (15270, delta 0.1%), NVIDIA GeForce RTX 3050 OEM (15199, delta 0.6%), and AMD Radeon RX 7600 (15171, delta 0.8%). These deltas are all under 1%, meaning the RTX 2060 performs nearly identically to these cards in synthetic tests. However, in Rust, the 6 GB VRAM may cause it to fall behind newer cards with more memory at high settings, as seen in the 4K Ultra result of 22 FPS.

The GPU’s DirectX 12 Ultimate support (12_2) and Vulkan 1.4 are modern, but its FP32 throughput of 6.451 TFLOPS is modest by current standards. The pixel rate of 80.64 GPixel/s and texture rate of 201.6 GTexel/s are sufficient for 1080p, but at 4K, the fill rate becomes a bottleneck. The measured FPS at 4K High (29 avg) and Ultra (22 avg) confirm that the GPU cannot sustain high-quality rendering at that resolution.

Resolution Scaling

The measured FPS data shows how the combo scales from 1080p to 4K. At Low settings, the average FPS is 126 at 1920x1080, 86 at 2560x1440, and 51 at 3840x2160. That is a 32% drop from 1080p to 1440p and a 41% drop from 1440p to 4K, or a 60% drop overall from 1080p to 4K. At Medium settings, the FPS goes from 84 (1080p) to 58 (1440p) to 34 (4K), a 31% and 41% drop respectively, totaling 60% less from 1080p to 4K. At High settings, it falls from 71 (1080p) to 49 (1440p) to 29 (4K), a 31% and 41% drop, again 60% overall. At Ultra, the numbers are 54 (1080p), 37 (1440p), and 22 (4K), with the same 31% and 41% drops, totaling 59% less.

This consistent scaling pattern—roughly 31% reduction from 1080p to 1440p and 41% from 1440p to 4K—indicates that the GPU is the limiting component. The number of pixels quadruples from 1080p to 4K, but the FPS does not halve; instead, it drops by about 60%. This suggests that while the GPU is heavily taxed, there is some headroom in the CPU or that the game’s engine is not purely pixel-bound. However, the fact that the percentage drops are identical across settings (Low through Ultra) implies that the bottleneck is consistent, not setting-dependent.

If the CPU were the limiter, we would expect FPS to remain similar across resolutions, but that is not the case. For instance, at 1080p Low, the combo hits 126 FPS, but at 4K Low it drops to 51. The CPU’s benchmark scores (e.g., 47737 in Cinebench R23 multicore) are far higher than what Rust needs for 126 FPS, so the GPU’s fill rate and memory bandwidth are what hold back higher resolutions. The 6 GB VRAM is also a factor; at 4K Ultra, the game likely requires more than 6 GB, causing the 22 FPS result.

The min FPS data (available only for Medium settings) reinforces this: at 1080p Medium, min FPS is 72, while at 1440p Medium it is 49, and at 4K Medium it is 29. These min FPS values show that even the frame pacing degrades with resolution, consistent with GPU memory pressure. The max FPS at 1080p Medium is 97, at 1440p Medium 67, and at 4K Medium 39, further confirming that the GPU cannot keep up with higher pixel counts.

Settings Recommendations

Based on the measured FPS, the best experience depends on resolution. At 1920x1080, Medium is the sweet spot: 84 avg FPS with a min of 72 and max of 97. This provides a smooth, responsive experience while maintaining decent visual quality. High at 71 avg FPS is also playable, but the 13 FPS drop from Medium may not be worth the visual gain. Ultra at 54 avg FPS is borderline; it is above 50 FPS but may suffer from stutter in busy scenes. Low at 126 avg FPS is excellent for competitive play, but it sacrifices most visual fidelity.

At 2560x1440, Low is the only preset that exceeds 60 FPS, hitting 86 avg. Medium at 58 avg FPS is close, but the min FPS of 49 suggests occasional dips below 50, which could be noticeable. High at 49 avg FPS and Ultra at 37 avg FPS are not recommended for a fluid experience. If you have a 1440p monitor, Low is the practical choice, with Medium as a compromise if you can tolerate frame drops.

At 3840x2160, all presets are below 60 FPS. Low at 51 avg FPS is the most playable, but it is still under 60. Medium at 34, High at 29, and Ultra at 22 are all too low for smooth gameplay. For 4K, the data shows that this combo is not suitable for anything beyond Low settings, and even that is marginal. If you own a 4K display, you should either lower the resolution or accept sub-60 FPS.

The pattern across all resolutions is that Low settings provide the highest FPS, but the gap between Low and Medium is significant. For example, at 1080p, the drop from Low to Medium is 42 FPS (126 to 84), while the drop from Medium to High is only 13 FPS (84 to 71). This suggests that the Medium preset introduces a large performance cost, likely due to increased shading and texture quality. If you want the best visual quality per frame, High at 1080p (71 FPS) is a reasonable choice, but Medium offers a better balance.

How This Combo Ranks

In the benchmark database, this specific combo (AMD Ryzen 9 9900X3D + NVIDIA GeForce RTX 2060) ranks 2303 out of 2953 tested combinations in Rust. That places it in the bottom 22% of all combos. This low ranking is surprising given the CPU’s strength, but it underscores the GPU’s limitations.

The Ryzen 9 9900X3D is a 12-core, 24-thread processor from the 9000 series, based on Zen 5 architecture (Granite Ridge) on a 4 nm process. It has a base clock of 4.40 GHz and boost clock of 5.50 GHz, with a TDP of 120 W. Its benchmarks are impressive: Cinebench R23 multicore scores 47737, Geekbench multicore 22884, and PassMark multithread 56154. The CPU’s percentileVsAllCpus is 91, meaning it outperforms 91% of all CPUs. Its nearest rivals include the Intel Core Ultra 5 245KF (avg score 55093, delta -0.6%), Intel Core Ultra 5 245K (54053, delta 1.3%), Intel Xeon 6505P (53701, delta 2%), and Intel Core i7-14700F (53620, delta 2.1%). The CPU’s avg benchmark score is 54762, which is within 1% of these rivals.

In contrast, the RTX 2060 has a percentileVsAllGpus of 58, meaning it outperforms 58% of GPUs. Its avg benchmark score is 15290, with nearest rivals all within 0.8% (GTX 580 at 15283, Radeon 680M at 15270, RTX 3050 OEM at 15199, RX 7600 at 15171). The GPU’s PassMark G3D score of 14111 is modest, and its 6 GB VRAM is a limiting factor for modern games.

The combo rank of 2303 out of 2953 suggests that many other CPU+GPU pairings deliver better Rust performance. This is because Rust is heavily GPU-bound at higher settings, and the RTX 2060 is a mid-range card from 2019. The CPU, while powerful, cannot compensate for the GPU’s lack of raw throughput and memory. If you were to pair this CPU with a more capable GPU (e.g., one with higher PassMark G3D score), the rank would likely improve significantly, but the data only covers this exact combo.

The fact that the CPU’s percentile (91) is far higher than the GPU’s (58) indicates a significant imbalance. This imbalance is reflected in the measured FPS: at 1080p Low, the combo hits 126 FPS, which is CPU-friendly, but at 4K Ultra, it drops to 22 FPS, which is GPU-limited. The combo rank correctly captures this overall weakness.

Measured FPS Breakdown

The measured FPS data covers four resolutions (1920x1080, 2560x1440, 3840x2160) and four settings (Low, Medium, High, Ultra). Here is the full breakdown:

1920x1080 (1080p):

• Low: avg 126 FPS
• Medium: avg 84 FPS, min 72, max 97
• High: avg 71 FPS
• Ultra: avg 54 FPS

At 1080p, the combo is most capable. Low hits 126 FPS, which is excellent for fast-paced gameplay. Medium drops to 84 FPS, still above 60, with a min of 72 ensuring no significant dips. High at 71 FPS is playable but not as smooth. Ultra at 54 FPS is below 60, so it is not ideal for a 144Hz monitor, but it may be acceptable on a 60Hz display.

2560x1440 (1440p):

• Low: avg 86 FPS
• Medium: avg 58 FPS, min 49, max 67
• High: avg 49 FPS
• Ultra: avg 37 FPS

At 1440p, the GPU begins to struggle. Low is the only preset above 60 FPS (86), which is good but not great. Medium falls to 58 FPS, with a min of 49 indicating occasional drops below 50. High at 49 FPS and Ultra at 37 FPS are both below playable thresholds for most users. If you have a 1440p monitor, Low is the recommended setting, with Medium as a compromise if you can handle frame dips.

3840x2160 (4K):

• Low: avg 51 FPS
• Medium: avg 34 FPS, min 29, max 39
• High: avg 29 FPS
• Ultra: avg 22 FPS

At 4K, the combo is severely GPU-limited. Low at 51 FPS is just over half of 60, but it is the only preset above 50. Medium at 34 FPS, High at 29, and Ultra at 22 are all unplayable for a smooth experience. The min FPS at Medium (29) and max (39) show that even the best-case scenario is below 40 FPS. For 4K gaming, this combo is not recommended unless you are willing to play at Low settings and accept sub-60 FPS.

The data also shows a clear trend: as resolution increases, the FPS drops proportionally across all settings. For example, the difference between Low and Ultra at 1080p is 72 FPS (126 to 54), at 1440p it is 49 FPS (86 to 37), and at 4K it is 29 FPS (51 to 22). This indicates that the GPU’s performance ceiling is reached at 1080p Ultra, and higher resolutions require lower settings to maintain playable frame rates.

In summary, the Ryzen 9 9900X3D + RTX 2060 combo is best suited for 1080p gaming, where it can handle Medium to High settings with ease. At 1440p, only Low settings provide 60+ FPS, and at 4K, even Low is marginal. The CPU is not the bottleneck; the GPU’s 6 GB VRAM and older architecture are. If you prioritize high frame rates, stick to 1080p Medium or Low. If you need higher resolutions, consider a GPU upgrade, as the CPU has plenty of headroom.
