Rust

Rust is a demanding survival title, and the combination of the Intel Core Ultra 9 275HX with the AMD Radeon 880M integrated graphics produces results that are firmly at the lower end of the spectrum. The data places this combo at rank 2878 out of 2953 tested configurations, meaning it outperforms only about 2.5% of all recorded setups. This is a clear indicator that the integrated GPU is the primary bottleneck, as the CPU is a high-end mobile part with substantial processing power. The measured frame rates confirm that this pairing is not suited for high-refresh-rate or high-resolution play, but it does offer a playable experience at lower settings and resolutions.

How This Combo Ranks

The combo's position at rank 2878 out of 2953 in Rust is a stark reflection of its performance ceiling. This places it in the bottom 10% of all tested combinations, underscoring that the AMD Radeon 880M is not a gaming powerhouse. The ranking is heavily influenced by the GPU's limitations, as the CPU is a top-tier component that ranks in the 94th percentile against all other processors. This mismatch creates a system where the processor is vastly underutilized in gaming scenarios, waiting on the integrated graphics to render each frame.

When looking at the individual components, the disparity becomes even clearer. The Intel Core Ultra 9 275HX has an average benchmark score of 67469, which is nearly identical to its nearest rivals. It is a mere 0.3% slower than the Intel Xeon w5-3525 and 0.5% slower than the AMD EPYC 4484PX. This shows that the CPU is performing exactly as expected for a processor of its class. In contrast, the AMD Radeon 880M has an average benchmark score of 8436, which puts it in the 43rd percentile of all GPUs. Its closest rival, the NVIDIA GeForce GTX 675MX, is a 0.1% faster, while the NVIDIA GeForce MX330 is 0.3% faster. This indicates that the GPU is not just underpowered for modern gaming; it is performing at a level comparable to decade-old discrete mobile graphics solutions.

The data suggests that the benchmark results are almost entirely GPU-bound. The CPU's massive lead in processing power—evidenced by its 35589 score in Cinebench R23 multi-core—cannot compensate for the GPU's inability to push frames. In this context, the combo rank is a measure of the weakest link, and that link is clearly the integrated graphics. Users should expect performance akin to entry-level laptops from several years ago, not a modern gaming machine.

GPU Role

The AMD Radeon 880M is an integrated graphics processor based on the RDNA 3.5 architecture, built on a 4nm process. It operates with a base clock of 400 MHz and a boost clock of 2900 MHz, which is a significant range that allows for dynamic power scaling. The GPU features 768 shading units, 48 texture mapping units, and 16 raster output units, along with 12 ray tracing cores. Its compute power is rated at 4.454 TFLOPS for FP32 operations, which is modest for modern gaming. The GPU's memory is system-shared, meaning its performance is heavily dependent on the system's RAM and memory bandwidth, which is listed as "System Dependent."

In Rust, the GPU's role is to handle all the rendering, and its performance directly dictates the frame rates. The boost clock of 2900 MHz is high for an integrated solution, but the limited number of shading units and the shared memory bandwidth severely restrict its output. The GPU's average benchmark score of 7615 in Passmark G3D places it in the 43rd percentile, reinforcing its mid-to-low-tier status. The results in Rust are consistent with this assessment, as the GPU struggles to maintain playable frame rates even at 1080p.

The 880M's performance is comparable to the NVIDIA GeForce GTX 675MX, which is a 2012-era mobile GPU. This comparison highlights the technological gap between integrated and discrete solutions. In Rust, the GPU's bottleneck is most evident in the scaling from Low to Ultra settings, where the frame rate drops by more than half. The GPU simply does not have the raw throughput to handle the increased shader complexity and draw calls at higher settings, making it the definitive limiting factor in this combo.

Resolution Scaling

The frame rate data shows a predictable and steep decline as resolution increases, which is a classic sign of a GPU-bound system. At 1080p with Low settings, the combo achieves an average of 64 FPS. Moving to 1440p at the same settings, the average drops to 44 FPS, a 31% reduction. At 4K with Low settings, the average falls to 26 FPS, which is a 59% reduction from the 1080p result. This scaling pattern indicates that the GPU is being saturated by the increasing pixel count, and the CPU is not the limiting factor.

The same trend is visible at High settings, where the average FPS goes from 36 at 1080p to 25 at 1440p and finally to 15 at 4K. The drop from 1080p to 4K is a 58% loss in performance. This consistent percentage drop across different settings strongly suggests that the rendering pipeline is GPU-limited. If the CPU were the bottleneck, the frame rates would show less variation with resolution changes, as the CPU workload would remain relatively constant. Instead, the data shows that the GPU's fill rate and pixel throughput are the primary constraints.

The implication for users is that lowering the resolution is the most effective way to gain performance in Rust. The jump from 4K to 1080p at Low settings nearly triples the frame rate, from 26 FPS to 64 FPS. However, even at 1080p, the system cannot maintain high frame rates at higher settings. This indicates that users will need to prioritize resolution and settings to achieve a smooth experience, and that the system is best suited for 1080p gaming at low-to-medium presets.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the combo's performance across three resolutions and four quality presets. At 1920x1080, the system delivers an average of 64 FPS on Low settings, which is the only configuration that approaches a smooth experience. Medium settings at 1080p produce an average of 43 FPS, with a minimum of 37 FPS and a maximum of 50 FPS, which is playable but with noticeable frame time variance. High settings drop the average to 36 FPS, and Ultra settings bring it down to 28 FPS, making these presets less desirable for competitive play.

Moving to 2560x1440, the performance degrades further. Low settings yield an average of 44 FPS, which is still playable but with a noticeable drop from 1080p. Medium settings at 1440p average 30 FPS, with a minimum of 25 FPS and a maximum of 34 FPS, which can feel choppy in fast-paced scenarios. High settings average 25 FPS, and Ultra settings drop to 19 FPS, making these presets largely unplayable for a smooth experience.

At 3840x2160, the system is severely challenged. Low settings produce an average of 26 FPS, which is borderline playable but with significant stuttering. Medium settings average 18 FPS, with a minimum of 15 FPS and a maximum of 20 FPS, which is not a comfortable experience. High settings average 15 FPS, and Ultra settings drop to 11 FPS, rendering the game nearly unplayable. The data clearly shows that 4K is not a viable resolution for this combo, and that 1080p with Low or Medium settings is the only path to a playable experience.

CPU Role

The Intel Core Ultra 9 275HX is a formidable mobile processor, featuring 24 cores and 24 threads based on the Arrow Lake architecture. It has a base clock of 2.70 GHz and a boost clock of 5.40 GHz, with a TDP of 55W. The CPU includes 36 MB of shared L3 cache and supports DDR5 memory with a dual-channel bus, providing a memory bandwidth of 102.4 GB/s. Its benchmark scores are exceptional, with a Cinebench R23 multi-core score of 35589 and a single-core score of 2204. This places the CPU in the 94th percentile of all processors, making it one of the most powerful mobile chips available.

In Rust, the CPU's role is to handle game logic, physics, and entity updates. While Rust is known to be CPU-intensive, especially on servers with many players and structures, the data suggests that this CPU is not the bottleneck in this configuration. The frame rates scale dramatically with resolution and settings, which is a hallmark of a GPU-limited scenario. The CPU's massive multi-threading capabilities are largely underutilized because the GPU cannot render frames fast enough to keep up. The CPU's high single-core performance, evidenced by its Cinebench R15 single-core score of 334, ensures that it can handle the main game thread efficiently, but it is left waiting for the GPU to complete its rendering tasks.

The CPU's performance relative to its nearest rivals further confirms its capability. It is virtually tied with the Intel Xeon w5-3525, being only 0.3% slower. This means that in a system with a more powerful discrete GPU, this CPU would not be a limiting factor in most gaming scenarios. However, in this combo, the CPU's potential is wasted. The data indicates that the system is severely imbalanced, with a top-tier CPU paired with a low-end integrated GPU. Users should be aware that upgrading the GPU in the future would unlock the CPU's full potential, but as it stands, the CPU is waiting on the GPU to deliver every frame.
