Rust

Rust with an Intel Core Ultra 9 290K Plus and an AMD Radeon RX 5700 XT presents a clear case of GPU-bound performance at higher resolutions, while the CPU’s substantial headroom becomes apparent only when the load drops. The measured frame rates across the three resolutions and four quality presets show a system where the Radeon RX 5700 XT, a card from the RDNA 1.0 era, dictates the experience in most scenarios. This combination ranks 2175th out of 2953 tested combos in Rust, placing it in the lower-mid portion of the database, a position that aligns with the GPU’s 59th percentile ranking among all GPUs.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a textbook GPU-limited scenario. At 1080p with Low settings, the system achieves 135 FPS. Moving to 1440p drops that to 93 FPS, a 31% reduction, and then to 4K it falls to 55 FPS, a 41% reduction from 1440p. This steep decline as pixel count increases is the signature of a graphics card working at its limits. The CPU, with its 24 cores and 5.80 GHz boost clock, is not the constraint here; the data suggests that the RX 5700 XT’s 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are being saturated.

The scaling pattern becomes even more telling at higher settings. With High settings, the frame rate goes from 76 FPS at 1080p to 52 FPS at 1440p, a 32% drop, and then to 31 FPS at 4K, a 40% drop from 1440p. The relative performance loss between resolutions remains consistent, hovering around 30-40%, which indicates that the GPU is the primary bottleneck across all tested configurations. If the CPU were the limiting factor, we would expect to see a smaller performance delta between 1440p and 4K, as the resolution increase would have less impact on a processor-bound workload.

At 4K Ultra, the system bottoms out at 24 FPS, which is barely playable. The jump from 1080p Ultra (58 FPS) to 4K Ultra (24 FPS) represents a 59% reduction in performance. This severe drop underscores that the RX 5700 XT is not designed for 4K gaming at maximum quality settings in a demanding title like Rust. The data suggests that users targeting 4K would need to significantly lower settings to achieve a playable frame rate, as even Low settings only manage 55 FPS at that resolution.

FAQ

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

A: The data shows that 1920x1080 is the only resolution where the system consistently delivers high frame rates. At 1080p, even Ultra settings achieve 58 FPS, while Low settings reach 135 FPS. At 1440p, the frame rates drop to a range of 40-93 FPS depending on settings, and at 4K, the system struggles to maintain 55 FPS even on Low.

Q: How much of a performance difference is there between Low and Ultra settings?

A: The gap is substantial across all resolutions. At 1080p, Low settings produce 135 FPS while Ultra produces 58 FPS, a difference of 77 FPS. This gap narrows slightly at higher resolutions; at 1440p the difference is 53 FPS (93 vs 40), and at 4K it is 31 FPS (55 vs 24). The relative performance cost of Ultra settings is highest at lower resolutions.

Q: Is the Intel Core Ultra 9 290K Plus holding back the Radeon RX 5700 XT?

A: Benchmark data suggests not. The CPU scores 51,731 in Cinebench R23 multi-core and 7,303 in single-core, placing it in the 96th percentile of all CPUs. The frame rate scaling between resolutions indicates the GPU is the limiting factor. The CPU is capable of feeding the GPU far more frames than the RX 5700 XT can render.

Q: Can this system handle 4K gaming in Rust?

A: Only at very low settings. At 4K Low, the system achieves 55 FPS, which is playable. However, at 4K Medium it drops to 37 FPS, and at 4K High it falls to 31 FPS. 4K Ultra is not viable at 24 FPS. The 8 GB VRAM of the RX 5700 XT is a limiting factor at this resolution.

Q: How does the RX 5700 XT compare to its nearest rivals?

A: The RX 5700 XT has an average benchmark score of 16,361. Its nearest rival, the AMD Radeon Pro 5600M, scores 16,351, which is a 0.1% difference. The NVIDIA RTX PRO 6000 Blackwell scores 16,408, a -0.3% delta, and the AMD Radeon PRO W7500 scores 16,415, also a -0.3% delta. The performance is effectively identical among these cards.

Q: What is the expected frame time consistency for this combo?

A: The data provides minimum and maximum FPS for Medium settings only. At 1080p Medium, the average is 90 FPS with a minimum of 77 and a maximum of 104. At 1440p Medium, the average is 62 FPS with a range of 53 to 71. At 4K Medium, the average is 37 FPS with a range of 31 to 42. This suggests relatively stable frame pacing at Medium settings.

GPU Role

The AMD Radeon RX 5700 XT is the dominant component in this pairing, and its specifications explain the measured results. The GPU features 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth. This memory configuration is a critical factor in Rust, a game known for its large, persistent world and frequent asset streaming. At 4K resolution, the 8 GB frame buffer becomes a constraint, which is why the frame rates drop so dramatically at higher settings.

The GPU’s clock speeds are also relevant. With a base clock of 1605 MHz and a boost clock of 1905 MHz, the RX 5700 XT is running at a high frequency for its generation. The game clock of 1755 MHz represents the typical sustained clock during gaming workloads. These clocks, combined with 2560 shading units, allow the card to produce 9.754 TFLOPS of FP32 compute. However, this compute power is insufficient for the demands of 4K Ultra in Rust, as evidenced by the 24 FPS result.

The RX 5700 XT’s position in the market is clear from its benchmarks. It scores 16,277 in Passmark G3D and has a percentile rank of 59 among all GPUs. Its nearest rivals, the AMD Radeon Pro 5600M and the NVIDIA RTX PRO 6000 Blackwell, are within 0.3% of its average score, indicating that it is a mid-range performer. This aligns with its measured performance in Rust, where it provides playable frame rates at 1080p and 1440p but struggles at 4K.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user’s resolution and performance target. For 1080p, the High preset offers the best balance of visual quality and performance, delivering 76 FPS. This is well above the 60 FPS threshold for smooth gameplay. The Medium preset at 90 FPS is also viable, but the 14 FPS gain over High may not justify the visual downgrade. Low settings at 135 FPS are only recommended for competitive play where maximum frame rate is paramount.

At 1440p, the High preset drops to 52 FPS, which is playable but not ideal for fast-paced action. The Medium preset at 62 FPS provides a better experience, and this is the recommended setting for 1440p. The Low preset at 93 FPS is the only way to achieve a high refresh rate experience at this resolution, but the visual quality will be noticeably reduced. Ultra settings at 40 FPS are not recommended due to the drop below 60 FPS.

For 4K, the options are limited. Low settings at 55 FPS is the only preset that provides a playable experience. Medium at 37 FPS and High at 31 FPS are both below the playable threshold for most users. Ultra at 24 FPS is essentially a slideshow. Therefore, the recommendation for 4K is to use Low settings and accept the visual compromises, or to lower the resolution to 1440p.

Measured FPS Breakdown

The complete measured FPS dataset provides a comprehensive view of the system’s capabilities. At 1920x1080, the frame rates are as follows: Low settings produce an average of 135 FPS, Medium produces 90 FPS (with a minimum of 77 and maximum of 104), High produces 76 FPS, and Ultra produces 58 FPS. This shows a clear progression where each step up in quality costs roughly 15-20 FPS.

At 2560x1440, the performance drops significantly. Low settings produce 93 FPS, Medium produces 62 FPS (minimum 53, maximum 71), High produces 52 FPS, and Ultra produces 40 FPS. The gap between Low and Ultra narrows to 53 FPS, compared to 77 FPS at 1080p. This indicates that the GPU is becoming the bottleneck, and the CPU’s ability to push higher frame rates is being limited.

At 3840x2160, the system is severely GPU-bound. Low settings produce 55 FPS, Medium produces 37 FPS (minimum 31, maximum 42), High produces 31 FPS, and Ultra produces 24 FPS. The difference between Low and Ultra is only 31 FPS, and even the highest performing setting at this resolution is below 60 FPS. The data clearly shows that 4K is beyond the comfortable range for this GPU in Rust.

CPU Role

The Intel Core Ultra 9 290K Plus is a high-end processor that is not the limiting factor in this configuration. Its benchmark scores are exceptional, with a Cinebench R23 multi-core score of 51,731 and a single-core score of 7,303. The Passmark single-thread score of 4,823 and multithread score of 60,860 further demonstrate its capability. This CPU is in the 96th percentile of all CPUs, meaning it outperforms 96% of processors in the database.

The CPU’s specifications support its strong performance. It has 24 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.80 GHz. The 36 MB of shared L3 cache and 3 MB per-core L2 cache provide ample fast memory for game data. The process node is 3 nm from TSMC, and the CPU uses the Intel Socket 1851. Its nearest rival, the Intel Core Ultra 9 285K, has an average score of 83,807, which is a 0.2% delta from this CPU’s 84,003 average score.

In Rust, the CPU’s role is to handle game logic, physics, and entity updates, while the GPU handles rendering. The measured FPS data shows that the CPU is capable of delivering far more frames than the GPU can render, as evidenced by the 135 FPS at 1080p Low. The fact that frame rates drop by 30-40% when moving from 1080p to 1440p, and again from 1440p to 4K, proves that the GPU is the primary bottleneck. The CPU is operating well within its limits, providing a stable foundation for the RX 5700 XT to work from.
