Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, and the pairing of the Intel Core Ultra X9 388H with the AMD Radeon 880M integrated graphics produces a very specific performance profile. The measured data places this combination near the bottom of the database, indicating that the experience is heavily constrained by the graphics solution. This analysis breaks down the benchmark results, focusing on how the components interact with the simulator's engine at various resolutions and settings.

How This Combo Ranks

The Core Ultra X9 388H and Radeon 880M combo ranks 2924 out of 2996 tested combinations for Microsoft Flight Simulator. This places it in the bottom 2.5% of all tested systems, which is a critical starting point for understanding its capabilities. The rank reflects the reality that while the CPU is a strong performer in general compute tasks, the integrated GPU is the limiting factor in this specific flight simulator.

Benchmark results indicate that this pairing is not designed for high-refresh-rate or high-fidelity flight simulation. The rank is a direct consequence of the GPU's performance ceiling, which is significantly lower than what the simulator's engine can utilize. Even at the lowest settings, the frame rates remain modest, confirming that the bottleneck is consistent across all graphical configurations.

To contextualize the CPU's potential, it scores at the 88th percentile of all CPUs, with an average benchmark score of 44466. Its nearest rivals include the AMD Ryzen 5 7500X3D (with a delta of -0.2%) and the Intel Core i9-13950HX (with a delta of 0.3%). This shows the processor is not the primary issue; in a system with a discrete GPU, this CPU would likely rank much higher. The combination's low rank is almost entirely attributable to the integrated Radeon 880M, which sits at the 43rd percentile of all GPUs, with an average score of 8436.

GPU Role

The AMD Radeon 880M is an integrated graphics processor based on the RDNA 3.5 architecture, built on a 4 nm process. It operates with a base clock of 400 MHz and a boost clock of 2900 MHz. The GPU has 768 shading units, 48 TMUs, and 16 ROPs, which are modest numbers that explain its performance constraints. Its compute capability is rated at 4.454 TFLOPS for FP32 operations, a figure that is simply insufficient for the heavy rendering load of Microsoft Flight Simulator at higher resolutions.

The GPU's memory configuration is "System Shared," meaning it relies on the system's main memory. Its bandwidth is listed as "System Dependent," which in this case is paired with the CPU's dual-channel LPDDR5X memory interface providing 153.6 GB/s of bandwidth. This shared architecture is a significant bottleneck, as the GPU and CPU compete for the same memory resources, further limiting performance in a game that is both CPU and memory intensive.

In this game's results, the GPU's role is the dominant factor. The measured FPS shows that at 1080p Ultra, the average is 26 FPS, while at 1080p Low, it rises to 47 FPS. This scaling of roughly 1.8x between the lowest and highest settings demonstrates that the GPU is under severe stress. The data suggests that the Radeon 880M's raw shader and texture processing power, along with its shared memory bandwidth, are the primary constraints, preventing the high core count of the CPU from being fully utilized in this scenario.

Resolution Scaling

The measured FPS data reveals a clear and expected trend: performance degrades as resolution increases, confirming that the GPU is the limiting component. The frame rate drop from 1080p to 4K is substantial across all settings, which is characteristic of a system where the graphics processor is oversaturated.

At Low settings, the average FPS drops from 47 FPS at 1920x1080 to 38 FPS at 2560x1440, and further down to 28 FPS at 3840x2160. This represents a 40% reduction in performance from 1080p to 4K. At Medium settings, the drop is from 37 FPS at 1080p to 29 FPS at 1440p and 22 FPS at 4K. The High settings row shows a similar pattern, going from 28 FPS at 1080p to 22 FPS at 1440p and finally 16 FPS at 4K.

This scaling pattern is a textbook example of a GPU-bound scenario. The consistent decline in frame rates with each resolution step indicates that the GPU's fill rate and memory bandwidth are being exhausted. The CPU, which is a high-performance part, is not the bottleneck here; if it were, the frame rates would remain relatively flat across resolutions. The data shows that the Radeon 880M simply cannot handle the pixel count of 4K (3840x2160), resulting in an unplayable experience, while 1080p remains the only viable target for this integrated solution.

Settings Recommendations

For this combination, the measured data offers a clear hierarchy of playable settings. The primary goal should be to achieve a stable frame rate above 30 FPS, which is often considered the minimum for a playable flight simulator experience.

At 1920x1080, the Low preset is the only setting that consistently achieves an average above 30 FPS, with a measured 47 FPS. This is the recommended preset for a smooth experience. The Medium preset at 1080p averages 37 FPS, which is also playable, but the margin for error is smaller, with a recorded minimum of 31 FPS. For users who prioritize visual fidelity over frame rate, the High preset at 1080p averages 28 FPS, which is below the 30 FPS threshold but may be acceptable for slower, more methodical flight.

Moving to 2560x1440 is not recommended for playable frame rates. Even the Low preset averages 38 FPS, but the Medium preset drops to 29 FPS, and High and Ultra fall to 22 FPS and 21 FPS respectively. At 3840x2160, all settings are below playable thresholds, with the best case being 28 FPS on Low. The data supports a simple recommendation: for the best balance of smoothness, use the Low preset at 1080p. For a more visually detailed experience, the Medium preset at 1080p is the highest setting that remains in the playable range.

CPU Role

The Intel Core Ultra X9 388H is a 16-core, 16-thread processor based on the Panther Lake architecture, built on a 3 nm process. It has a base clock of 2.10 GHz and a boost clock of 5.10 GHz. Its cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and a shared 18 MB of L3 cache. This is a high-performance mobile processor, as evidenced by its Cinebench R23 multi-core score of 18911 and single-core score of 2200.5.

In the context of Microsoft Flight Simulator, the CPU's role is to handle the complex simulation logic, physics, and AI. The data from the benchmark shows that the CPU is not the bottleneck in this system. Its percentile rank of 88 indicates it is faster than the vast majority of CPUs in the database. When comparing it to its nearest rivals, the performance is essentially tied with the AMD Ryzen 5 7500X3D (-0.2%) and the Intel Core i9-13950HX (0.3%).

The fact that the frame rates scale so dramatically with resolution and settings points directly to the GPU being the limiting factor. If the CPU were the bottleneck, the frame rates would be more consistent across different resolutions. The CPU's high single-thread performance, as shown by its Cinebench R15 single-core score of 309.5, is crucial for this game, as it relies heavily on a few main threads. However, this processing power is left largely underutilized because the integrated GPU cannot feed frames to the display fast enough.
