Rust

The AMD Ryzen 9 8945HX paired with the AMD Radeon 880M is a combination that struggles significantly in Rust, ranking 2878th out of 2953 tested combos. This places it in the bottom 3% of all configurations, a direct result of the integrated GPU being the system’s clear bottleneck. The data shows that even at the lowest settings and resolution, the frame rates barely cross into playable territory, making this a configuration for low-impact tasks rather than competitive survival gameplay.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, using the Dragon Range codename on a 5 nm TSMC process. Its base clock of 2.50 GHz can boost up to 5.40 GHz, and it carries 64 MB of L3 cache, with 1 MB of L2 cache per core. This is an exceptionally powerful mobile CPU, sitting in the 95th percentile against all CPUs, with an average benchmark score of 76212. Its nearest rival, the Intel Core Ultra 9 285HX, scores 76155, a delta of just 0.1%, meaning the two are effectively tied in raw CPU throughput.

However, in the context of Rust and this specific combo, the CPU’s potential is largely untapped. The measured FPS data shows that at 1920x1080 with Low settings, the system achieves 64 FPS on average. At the same resolution with High settings, it drops to 36 FPS. This pattern—a steep drop as settings increase—indicates that the GPU, not the CPU, is determining performance. The Ryzen 9’s single-thread performance is strong, evidenced by a Cinebench R23 single-core score of 6030, and its multi-core score of 42713 is massive. For a game like Rust, which can be sensitive to single-thread performance for world simulation and physics, this CPU is more than capable of feeding frames to a discrete GPU.

The issue is that the Radeon 880M is not that discrete GPU. The CPU’s PassMark single-thread score of 3907 and its physics score of 2168 suggest it can handle the game’s logic, but the rendering pipeline is starved. The 64 MB of L3 cache is beneficial for general workloads, but the game’s performance ceiling here is set by the graphics solution. When comparing to rivals, the AMD EPYC Embedded 8224P scores 76492 (a -0.4% delta), and the AMD Ryzen 9 9950X3D scores 75779 (a +0.6% delta), all within a 1% band. This confirms the CPU is operating at the top tier of available processors, yet the combo rank of 2878 out of 2953 proves that raw CPU power cannot compensate for an integrated GPU’s limitations in this title.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon 880M is an integrated GPU based on the RDNA 3.5 architecture, built on a 4 nm process. It has a base clock of 400 MHz and a boost clock of 2900 MHz. Its memory size, type, and bus width are all listed as "System Shared," meaning it uses the system’s DDR5 RAM, and its bandwidth is "System Dependent." This is the critical weakness. With 768 shading units, 48 TMUs, and 16 ROPs, the 880M offers 4.454 TFLOPS of FP32 performance. However, its benchmark scores are modest: a PassMark G3D score of 7615, placing it in the 43rd percentile of all GPUs.

The GPU’s nearest rivals are telling. The NVIDIA GeForce GTX 675MX scores 8427 (a 0.1% delta), the NVIDIA GeForce MX330 scores 8458 (a -0.3% delta), and the AMD Radeon HD 8870M scores 8462 (a -0.3% delta). These are all older discrete mobile GPUs, and the 880M is competitive with them in raw compute, but it lacks dedicated VRAM. The "System Shared" memory means the GPU must contend with the CPU for bandwidth, which is a severe handicap in a game like Rust that streams assets and textures.

This is reflected in the FPS data. At 3840x2160 with Ultra settings, the combo averages just 11 FPS. At 1920x1080 with Ultra settings, it only reaches 28 FPS. The jump from Low to Medium at 1920x1080 is from 64 FPS to 43 FPS, a 33% drop, showing how quickly the GPU saturates. The 880M’s DirectX 12 score of 32 and DirectX 11 score of 73 on PassMark indicate it can render frames, but the shared memory architecture and limited ROPs (16) are the primary constraints. The GPU’s average benchmark score is 8436, and its performance in Rust is consistently low, with no resolution or setting combination achieving a comfortable 60 FPS threshold except for the single 1920x1080 Low result of 64 FPS.

Settings Recommendations — which preset gives the best experience per the measured rows

The data is clear: the only playable experience is at 1920x1080 with Low settings, which yields an average of 64 FPS. This is the sole configuration that breaches the 60 FPS mark, and it does so by a narrow margin. All other settings at this resolution fall below playable thresholds for a competitive survival game. At 1920x1080 Medium, the average drops to 43 FPS, which is a significant 33% reduction from Low. High settings at 1080p reduce the average further to 36 FPS, and Ultra plummets to 28 FPS.

At 2560x1440, the situation worsens. Low settings produce 44 FPS, which is playable for some, but Medium drops to 30 FPS, High to 25 FPS, and Ultra to 19 FPS. At 3840x2160, all settings are effectively unplayable, with Low at 26 FPS, Medium at 18 FPS, High at 15 FPS, and Ultra at 11 FPS. The recommendation based on the measured rows is unequivocal: use 1920x1080 Low. This provides the highest average FPS and the only configuration that approaches smooth gameplay. The Medium preset at 1080p offers a 43 FPS average with a minimum of 37 FPS, which is a more consistent frame time but sacrifices overall smoothness. For users prioritizing visual fidelity over frame rate, 1080p Medium is the highest viable option, as High and Ultra at any resolution do not provide a competitive edge. The data suggests that no preset above Low at 1080p delivers a consistently good experience, and users should accept the visual trade-offs for functional performance.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 9 8945HX and AMD Radeon 880M combination ranks 2878th out of 2953 tested combos in Rust. This is a bottom-tier result, placing the system in the lowest 2.5% of all configurations tested. This rank is not a reflection of the CPU, which is a top-tier mobile processor, but rather the GPU’s inability to handle the game’s rendering demands. The combo’s ranking is consistent with the measured FPS data, which shows that even the best-case scenario (1080p Low) barely reaches playable levels.

When compared to other combos, this system sits far below any configuration using a discrete GPU, even older models. The GPU’s nearest rivals, like the GTX 675MX and HD 8870M, are legacy parts, and the 880M matches them in compute but fails to deliver higher frame rates due to shared memory constraints. The rank of 2878 out of 2953 means that 2877 other combinations performed better, and only 75 were worse. This is a critical data point for any user considering this hardware for Rust: it is not a viable gaming platform for this title. The CPU’s 95th percentile standing does not rescue the combo, as the GPU’s 43rd percentile and the game’s specific demands combine to produce a poor result. For context, the CPU’s rivals are all within 0.6% of its score, showing no CPU bottleneck, while the GPU’s rivals are also close, yet the overall system performance is severely constrained by the integrated graphics solution.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 3840x2160, the performance is consistently low across all presets. With Low settings, the average FPS is 26. Medium settings yield an average of 18 FPS, with a minimum of 15 and a maximum of 20. High settings produce an average of 15 FPS. Ultra settings are the worst, with an average of 11 FPS. No setting at this resolution achieves a playable frame rate, and the difference between Low and Ultra is only 15 FPS, showing diminishing returns as the GPU struggles with the pixel count.

At 2560x1440, the frame rates improve but remain marginal. Low settings achieve an average of 44 FPS. Medium settings produce an average of 30 FPS, with a range from 25 to 34 FPS. High settings average 25 FPS, and Ultra settings average 19 FPS. The step from Low to Medium is a 14 FPS drop, which is substantial, and the progression from Medium to High to Ultra shows a steady decline of 5-6 FPS per tier. This resolution is only viable at Low settings for a playable experience, and even then, it is below the 60 FPS target.

At 1920x1080, the best results are observed. Low settings deliver an average of 64 FPS, the only configuration to exceed 60 FPS. Medium settings produce an average of 43 FPS, with a minimum of 37 and a maximum of 50. High settings average 36 FPS, and Ultra settings average 28 FPS. The gap between Low and Medium is 21 FPS, which is the largest single-setting drop in the entire dataset. This indicates that the GPU’s memory bandwidth is severely taxed when moving beyond minimal settings. The data shows a clear hierarchy: 1080p Low is the only playable option, 1080p Medium is borderline, and all other settings and resolutions are below acceptable thresholds for smooth gameplay. The minimum FPS values recorded at Medium settings (37 at 1080p, 25 at 1440p, 15 at 4K) further illustrate the instability at higher presets, making those configurations unsuitable for consistent performance.
