Rust

The AMD Ryzen 9 9900X paired with the AMD Radeon RX 6600 XT ranks at 2671 out of 3723 tested combos in Rust. This places the combination in the lower-middle portion of the database, suggesting that while the hardware is capable, it does not deliver class-leading frame rates in this particular title. The CPU itself holds a strong 92nd percentile ranking among all processors, while the GPU sits at the 70th percentile among all graphics cards, indicating that the processor is the more dominant component in this pairing. The data shows a system that can produce playable frame rates at 1080p and 1440p, but struggles to maintain smooth performance at 4K, particularly at higher quality presets.

How This Combo Ranks

The 2671 position out of 3723 total combinations places this setup in roughly the 28th percentile of tested configurations for Rust. This is a notably lower ranking than what the individual component percentiles might suggest. The CPU's 92nd percentile standing and the GPU's 70th percentile standing do not translate into a top-tier gaming result for this title, which points to Rust's particular sensitivity to graphics memory capacity and bandwidth. The nearest rival data for the GPU reinforces this interpretation: the RX 6600 XT scores within 1.1% of the NVIDIA GeForce RTX 2080 SUPER, a much older card, and within 0.7% of the GTX 1630. This clustering around the 24,000 average benchmark score mark indicates that the RX 6600 XT's raw compute performance is competitive with those cards, yet the measured FPS in Rust reveals that real-world gaming performance can be constrained by other factors.

The CPU's nearest rivals show a tighter grouping, with the AMD EPYC 9015 just 0.1% behind and the Intel Core i9-14900 1.1% ahead in average benchmark scores. This indicates that the Ryzen 9 9900X is well-matched to other high-end processors in synthetic tests. However, the combo rank demonstrates that even a top-tier CPU cannot compensate for GPU limitations in Rust. The gap between the 138 FPS at 1080p Low and the 24 FPS at 4K Ultra reveals a performance cliff that is characteristic of a GPU-bound scenario. The data suggests that users seeking higher rankings would need to consider a graphics card with more memory or higher memory bandwidth, as the CPU clearly has headroom to drive more frames.

FAQ

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

A: The data shows that 1920x1080 provides the most consistent experience, with average frame rates ranging from 59 FPS at Ultra settings to 138 FPS at Low settings. At 2560x1440, the average drops to between 41 and 95 FPS depending on settings, while 3840x2160 yields only 24 to 56 FPS. The 1080p resolution is the only one where all settings presets maintain average frame rates above 59 FPS.

Q: How much performance is lost when moving from 1080p to 1440p?

A: At Medium settings, the average frame rate drops from 92 FPS at 1080p to 64 FPS at 1440p, representing a 30% reduction. At High settings, the drop is from 78 FPS to 54 FPS, a 31% decrease. At Low settings, the drop is from 138 FPS to 95 FPS, a 31% decrease. The consistency of this percentage across presets indicates a uniform scaling penalty.

Q: Is the CPU or GPU the limiting factor in this game?

A: The evidence points to the GPU as the primary bottleneck. The CPU holds a 92nd percentile ranking and has 12 cores with a boost clock of 5.60 GHz, yet the combo rank is only 2671 out of 3723. The GPU's 8 GB of GDDR6 memory and 256.0 GB/s bandwidth are likely insufficient for Rust's larger maps and asset streaming at higher resolutions. The sharp FPS drops at 4K settings reinforce this conclusion.

Q: Can this combo handle Ultra settings at any resolution?

A: At 1080p, Ultra settings produce an average of 59 FPS, which is playable but not high-refresh-rate territory. At 1440p, Ultra drops to 41 FPS, and at 4K it falls to 24 FPS. The data indicates that Ultra settings are only viable at 1080p for this pairing.

Q: How does the RX 6600 XT compare to its closest rivals in synthetic benchmarks?

A: The RX 6600 XT averages 24,442 in benchmark scores. It is 0.7% ahead of the GTX 1630, 0.8% behind the GTX 780 Ti, and 1.1% behind the RTX 2080 SUPER. The Intel Arc A350M trails by 0.8%. This shows that the GPU is competitive with older high-end cards but not with modern mid-range offerings.

Q: What is the lowest frame rate recorded for this combo?

A: The lowest average frame rate in the measured data is 24 FPS, recorded at 3840x2160 with Ultra settings. The minimum FPS values are only provided for Medium settings, where the lowest recorded minimum is 32 FPS at 4K and 78 FPS at 1080p.

Settings Recommendations

The measured data provides a clear picture of which settings preset offers the best balance of performance and visual quality. At 1920x1080, the Medium preset delivers 92 FPS average with a minimum of 78 FPS and a maximum of 106 FPS. This is a substantial improvement over the High preset's 78 FPS average, while still maintaining a smooth experience. The jump from Medium to High costs 14 FPS on average, which is a 15% reduction. For those who prioritize frame rate, the Low preset at 138 FPS is the best option, but it sacrifices visual fidelity.

At 2560x1440, the Medium preset becomes the recommended choice, producing 64 FPS average with a minimum of 54 FPS. This is above the 60 FPS threshold for smooth gameplay, though just barely. The High preset at 54 FPS is playable but not ideal for fast-paced situations. The Ultra preset at 41 FPS is not recommended for competitive play. At 3840x2160, no preset achieves a 60 FPS average; the Low preset comes closest at 56 FPS, but the Medium preset at 37 FPS is the highest quality option that remains playable.

The best overall experience for this combo is the Medium preset at 1080p. This configuration provides a 92 FPS average, which is high enough to benefit from a 144Hz monitor, while the minimum of 78 FPS ensures no severe stutters. The data indicates that the Medium preset at 1440p is the best alternative for users with higher-resolution displays, as it maintains a 64 FPS average. Users should avoid Ultra settings at resolutions above 1080p, as the frame rates fall below 41 FPS.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a steep performance gradient that is characteristic of a GPU-limited scenario. At Medium settings, the average FPS drops from 92 at 1080p to 64 at 1440p, a 30% reduction, and then to 37 at 4K, a further 42% reduction from 1440p. This pattern is consistent across all presets: at High settings, the drop is from 78 to 54 to 32 FPS; at Low settings, from 138 to 95 to 56 FPS; and at Ultra settings, from 59 to 41 to 24 FPS.

The percentage drop from 1080p to 1440p is remarkably consistent at around 30-31% across all presets. This uniformity indicates that the scaling is not dependent on the quality preset but rather on the pixel count increase. The drop from 1440p to 4K is more variable, ranging from 41% at High settings to 45% at Low settings. This suggests that the GPU is becoming increasingly saturated as the resolution increases.

The data indicates that the limiting component is the GPU. The CPU, with its 12 cores and 5.60 GHz boost clock, is capable of driving much higher frame rates, as evidenced by the 138 FPS at 1080p Low. The RX 6600 XT's 8 GB of memory and 256.0 GB/s bandwidth are the likely bottlenecks at higher resolutions. The 128-bit memory bus width is particularly restrictive for a game that streams large amounts of terrain and building data. Users should expect to choose between resolution and settings, as the combo cannot deliver high frame rates at both high resolution and high quality.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip and 32 ray tracing cores. Its 2048 shading units and 64 ROPs provide a peak pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s. The GPU's boost clock is listed at 2589 MHz with a game clock of 2359 MHz. These specifications place the card at the 70th percentile among all GPUs, with an average benchmark score of 24,442.

The memory configuration is the most critical factor for Rust. The 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth. This is sufficient for 1080p gaming but becomes a limiting factor at higher resolutions. The measured FPS data supports this: the GPU produces 138 FPS at 1080p Low but only 56 FPS at 4K Low. This 59% reduction in performance is more severe than what would be expected from pure pixel-count scaling, indicating memory bandwidth constraints.

The GPU's benchmark scores show it is closely matched with the RTX 2080 SUPER, which trails by just 1.1%. However, the RTX 2080 SUPER has a wider memory bus and more bandwidth, which likely explains why the RX 6600 XT's performance in Rust falls short of expectations. The GTX 1630, which is 0.7% behind in synthetic tests, would likely perform far worse in Rust due to its smaller memory configuration. This discrepancy highlights that synthetic benchmarks do not always predict gaming performance, especially for memory-intensive titles.

CPU Role

The AMD Ryzen 9 9900X is a high-end desktop processor with 12 cores and 24 threads, based on the Zen 5 architecture (Granite Ridge). It operates at a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a 120 W TDP. The processor has 64 MB of L3 cache and supports DDR5 memory with a dual-channel bus. Its average benchmark score is 57,498, placing it at the 92nd percentile of all CPUs.

In synthetic tests, the CPU excels at multi-threaded workloads, scoring 32,172 in Cinebench R23 multi-core and 22,174 in Geekbench multi-core. The single-thread performance is also strong, with 2,253 in Cinebench R23 single-core and 3,010 in Geekbench single-core. These scores indicate that the CPU has ample processing power for Rust's simulation and physics calculations. However, the measured FPS in Rust does not reflect this strength, as the combo rank is only 2671 out of 3723.

The CPU's nearest rivals include the AMD EPYC 9015, which is 0.1% slower, and the Intel Core i9-14900, which is 1.1% faster. This tight grouping suggests that the Ryzen 9 9900X is competitive with other top-tier processors. The data indicates that the CPU is not the bottleneck in this configuration. At 1080p Low, the system produces 138 FPS, and the CPU's multi-core capabilities would allow for even higher frame rates if the GPU could keep up. The 24 threads are more than sufficient for Rust's threading model, and the 5.60 GHz boost clock ensures strong single-thread performance for game logic.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. The Low preset achieves an average of 138 FPS, which is the highest frame rate recorded in the dataset. The Medium preset produces 92 FPS with a minimum of 78 FPS and a maximum of 106 FPS. The High preset averages 78 FPS, and the Ultra preset averages 59 FPS. The progression from Low to Ultra shows a steady decline, with Ultra being 57% slower than Low.

At 2560x1440, performance drops significantly. The Low preset averages 95 FPS, which is 31% lower than at 1080p. The Medium preset averages 64 FPS with a minimum of 54 FPS and a maximum of 73 FPS. The High preset averages 54 FPS, and the Ultra preset averages 41 FPS. The Medium preset is the only one that remains above 60 FPS on average.

At 3840x2160, the combo struggles to maintain playable frame rates. The Low preset averages 56 FPS, which is the only preset above 40 FPS. The Medium preset averages 37 FPS with a minimum of 32 FPS and a maximum of 43 FPS. The High preset averages 32 FPS, and the Ultra preset averages 24 FPS. The minimum FPS values are only provided for Medium settings, where the 4K minimum of 32 FPS is notably lower than the 1080p minimum of 78 FPS.

The data shows that the combo is best suited for 1080p gaming, where it can handle all presets with average frame rates above 59 FPS. At 1440p, users should stick to Medium or Low settings. At 4K, even Low settings cannot maintain a 60 FPS average, making this resolution unsuitable for smooth gameplay with this hardware.
