Rust

The AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 4080 Mobile combination ranks 1167th out of 3723 tested combos in Rust, placing it in the upper third of all systems evaluated. This mobile flagship pairing demonstrates strong headroom across most settings, though 4K Ultra remains beyond its reach. The data shows a system that is clearly capable of delivering smooth gameplay at 1080p and 1440p, with 4K requiring a compromise on visual fidelity.

How This Combo Ranks

The combo’s rank of 1167 out of 3723 tested combinations places it comfortably in the top 31% of all systems benchmarked for Rust. This is a strong showing for a mobile platform, reflecting the synergy between the 16-core Zen 4 CPU and the Ada Lovelace-based GPU. The CPU itself sits in the 95th percentile among all processors, while the GPU ranks in the 81st percentile among all graphics cards, indicating that neither component is a bottleneck in this pairing.

Looking at the CPU’s nearest rivals, the Ryzen 9 8945HX performs nearly identically to the Intel Core Ultra 9 285HX, with a delta of just 0.1% in average benchmark scores. The AMD chip also edges out the AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX by 0.4% each, while the Ryzen 9 9950X3D trails by 0.6%. These margins are negligible in real-world gaming scenarios, meaning the 8945HX delivers compute performance essentially on par with the best desktop and mobile processors available.

On the GPU side, the RTX 4080 Mobile’s average benchmark score of 38135 places it within 0.4% of the GeForce MX570 and 0.6% of the RTX 5080 Mobile. It also leads the RTX 4070 and Tesla P4 by 1.3%. This clustering suggests that the 4080 Mobile occupies a performance tier where small clock or thermal variations can shift rankings, but its overall capability is well established for high-refresh gaming.

FAQ

Q: How does the CPU compare to its closest rival?

A: The Ryzen 9 8945HX scores 76212 in average benchmarks, which is 0.1% higher than the Intel Core Ultra 9 285HX’s 76155. This places the two chips within statistical noise of each other.

Q: Is the GPU comparable to the RTX 4070?

A: The RTX 4080 Mobile’s average benchmark score of 38135 is 1.3% higher than the RTX 4070’s 37648, indicating the 4080 Mobile holds a slight but consistent edge.

Q: What FPS can I expect at 1080p with High settings?

A: The average frame rate is 117 FPS, with no minimum or maximum values recorded for this configuration. This provides ample headroom for competitive play.

Q: Does the system maintain 60 FPS at 4K Medium?

A: No, the 4K Medium preset averages 56 FPS with a minimum of 48 and a maximum of 65, meaning it dips below the playable threshold during demanding scenes.

Best Settings per Resolution

At 3840x2160, the most demanding preset that remains at or above 60 FPS is Low, which produces an average of 84 FPS. Medium falls short at 56 FPS average, making it unsuitable for consistent playability.

At 2560x1440, Ultra settings achieve 61 FPS average, just clearing the 60 FPS bar. This is the highest quality option available, with High at 81 FPS and Medium at 95 FPS providing additional headroom for those who prefer smoother motion.

At 1920x1080, Ultra settings deliver 89 FPS average, representing the best visual fidelity while maintaining well above the playable threshold. High settings reach 117 FPS, Medium 139 FPS, and Low 207 FPS for maximum performance.

Similar Performance Alternatives

The CPU’s nearest rivals indicate that systems built around the Intel Core Ultra 9 285HX would deliver nearly identical compute performance, with a delta of just 0.1%. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX are also within 0.4%, though these are server-class parts unlikely to appear in gaming laptops. The AMD Ryzen 9 9950X3D trails by 0.6%, making it a slightly slower but comparable alternative for multi-threaded workloads.

On the GPU side, the NVIDIA GeForce MX570 produces an average score within 0.4% of the RTX 4080 Mobile, suggesting similar rasterization performance despite its lower tier designation. The RTX 5080 Mobile is 0.6% slower in this benchmark, while the RTX 4070 and Tesla P4 are 1.3% behind. In practical terms, swapping the 4080 Mobile for any of these near-identical performers would yield frame rates within a few percent of those measured here.

For a full system comparison, pairing the Ryzen 9 8945HX with a GPU in the RTX 4070 performance class would produce very similar results in Rust, as the 1.3% GPU delta is unlikely to change the playable settings classification at any resolution. Conversely, using a slower CPU with the RTX 4080 Mobile might introduce CPU bottlenecks in the most CPU-intensive survival scenarios, though the 8945HX’s 16 cores and 32 threads provide substantial margin.

Measured FPS Breakdown

At 3840x2160, the data shows a clear progression across presets. Low settings produce an average of 84 FPS, Medium drops to 56 FPS with a minimum of 48 and maximum of 65, High averages 48 FPS, and Ultra falls to 36 FPS. The gap between Low and Medium is substantial, suggesting the GPU’s 12 GB VRAM and 192-bit memory bus become limiting factors as texture and shading complexity increases.

At 2560x1440, the system demonstrates solid performance across all presets. Low averages 142 FPS, Medium delivers 95 FPS with a range of 81 to 110, High reaches 81 FPS, and Ultra maintains 61 FPS. The minimum values recorded for Medium at 81 FPS indicate that even the most demanding scenes stay well above the 60 FPS threshold.

At 1920x1080, the RTX 4080 Mobile shows its strengths. Low settings hit 207 FPS average, Medium achieves 139 FPS with a minimum of 118 and maximum of 159, High averages 117 FPS, and Ultra delivers 89 FPS. The scaling from Ultra to Low represents a 2.3x performance increase, highlighting the GPU’s ability to push very high frame rates at lower settings.

The Verdict

This PC can run Rust effectively across most resolutions and presets. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra delivering 89 FPS average for a fully playable experience at maximum quality. The 2560x1440 resolution also supports Ultra settings at 61 FPS average, just above the playable threshold, while High and Medium provide more comfortable margins at 81 and 95 FPS respectively.

The situation changes at 3840x2160, where only Low settings achieve playable frame rates at 84 FPS average. Medium drops to 56 FPS, which falls below the 60 FPS bar, and High and Ultra are not viable at 48 and 36 FPS respectively. For 4K gaming, users must accept reduced visual quality, but the Low preset still delivers a smooth experience.

The verdictByResolution data confirms that this combo is best suited for 1080p and 1440p gaming, where it offers exceptional performance with headroom for future titles. The 4K results indicate that the RTX 4080 Mobile, despite its strong benchmark scores, does not have enough raw throughput for demanding survival games at full resolution with high fidelity settings. Overall, this system represents a high-end mobile gaming solution that excels at mainstream resolutions while requiring compromises at 4K.
