Microsoft Flight Simulator

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

The AMD Ryzen 9 8945HX is a 16-core, 32-thread mobile processor built on the Zen 4 architecture (Dragon Range codename) using a 5 nm TSMC process. It operates at a base clock of 2.50 GHz and boosts to 5.40 GHz, with a 55 W TDP. The chip carries 64 MB of L3 cache, 1 MB of L2 per core, and 64 KB of L1 per core, which totals a substantial cache hierarchy for a flight simulator that streams large terrain and scenery datasets. The processor supports DDR5 memory via a dual-channel interface with 83.2 GB/s bandwidth, and it connects through PCIe Gen 5 with 28 lanes (CPU only).

In the context of Microsoft Flight Simulator, the CPU's role is primarily about maintaining a stable simulation thread — the game's core loop handles physics, weather, and flight dynamics, which scale with single-thread performance. The Ryzen 9 8945HX posts a Cinebench R23 single-core score of 6030 and a multi-core score of 42713, with a Cinebench R20 single-core result of 2532 and multi-core of 17939. These numbers place the chip in the 95th percentile of all CPUs, with an average benchmark score of 76212. Its nearest rivals include the Intel Core Ultra 9 285HX (avg score 76155, deltaPct 0.1), the AMD EPYC Embedded 8224P (76492, -0.4), the AMD Ryzen Threadripper PRO 9945WX (76513, -0.4), and the AMD Ryzen 9 9950X3D (75779, 0.6). The deltas are tight — within 0.6% — meaning the 8945HX sits in a performance cluster where no single CPU dominates.

For Flight Simulator, the measured FPS data shows that at 1080p Low, the combo achieves 99 FPS average, which is the highest measured frame rate across all configurations. This suggests that at lower settings, the CPU is capable of feeding the GPU with enough draw calls and simulation updates to approach triple-digit frame rates. However, the game is known for heavy single-thread loads, and the 8945HX's single-core score of 607 in Cinebench R15 (and 3907 in PassMark single-thread) indicates strong per-core performance that helps avoid CPU-bound bottlenecks in less demanding visual scenarios. The 32 threads provide headroom for background tasks, but the measured results show that the CPU is not the limiting factor at high resolutions — the FPS drop from 1080p to 4K at the same settings is driven by GPU load, not CPU throughput.

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

Examining the measured FPS rows, the Medium preset consistently provides the best balance of smoothness and visual fidelity across all three resolutions. At 1080p Medium, the combo delivers 77 FPS average with a minimum of 65 and maximum of 88 FPS. At 1440p Medium, the average drops to 62 FPS with a range of 53 to 71 FPS. At 4K Medium, the average is 46 FPS with a minimum of 39 and maximum of 53 FPS. These Medium settings produce frame rates that are 40% higher than High at 1080p (77 vs 58), 32% higher at 1440p (62 vs 47), and 35% higher at 4K (46 vs 34).

The Low preset achieves the highest frame rates — 99 FPS at 1080p, 80 FPS at 1440p, and 59 FPS at 4K — but it sacrifices visual details that matter in a flight simulator, where terrain texture clarity and object density contribute to situational awareness. The Ultra preset, by contrast, yields the lowest averages: 55 FPS at 1080p, 44 FPS at 1440p, and 33 FPS at 4K. The gap between Medium and Ultra at 1080p is 22 FPS (77 vs 55), which is a 40% difference, while the gap between Low and Medium at 4K is 13 FPS (59 vs 46), a 28% improvement.

Benchmark results indicate that Medium is the sweet spot because it maintains playable frame rates at 1080p and 1440p (above 60 FPS average) while preserving enough graphical fidelity for the cockpit instruments and ground scenery. At 4K, Medium's 46 FPS average is marginally playable but may feel less smooth; users prioritizing frame rate at 4K should consider Low, which achieves 59 FPS. The data shows that the step from Medium to High incurs a substantial cost: at 1080p, High drops to 58 FPS (25% lower than Medium), and at 4K, High drops to 34 FPS (26% lower). Thus, the recommended preset is Medium for most use cases, with Low reserved for 4K users who demand frame rates above 60.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a consistent scaling pattern as resolution increases. At Low settings, the average FPS drops from 99 at 1080p to 80 at 1440p (a 19% decrease) and further to 59 at 4K (a 40% decrease from 1080p). At Medium settings, the progression is 77 → 62 → 46, representing a 19% drop from 1080p to 1440p and a 40% drop from 1080p to 4K. At High settings, the averages are 58 → 47 → 34, which is a 19% drop to 1440p and a 41% drop to 4K. At Ultra settings, the averages are 55 → 44 → 33, showing a 20% drop to 1440p and a 40% drop to 4K.

The near-identical percentage drops across all settings — roughly 19-20% from 1080p to 1440p and 40-41% from 1080p to 4K — indicate that the frame rate scaling is resolution-bound rather than settings-bound. This pattern is characteristic of a GPU-limited scenario: as pixel count increases from 2.07 million (1080p) to 3.69 million (1440p) to 8.29 million (4K), the rendering workload grows proportionally, and the GPU's fill rate and shading throughput become the primary constraint. The CPU, with its 16 cores and high single-thread performance, is not the bottleneck here; if it were, the FPS would remain relatively flat across resolutions.

The AMD Radeon 8050S GPU, with a boost clock of 2800 MHz and 2048 shading units, delivers 11.47 TFLOPS of FP32 performance. Its pixel rate is 179.2 GPixel/s and texture rate is 358.4 GTexel/s. These specifications, combined with the measured FPS data, show that the GPU is the limiting component at 4K, where even Low settings only produce 59 FPS. The 4K to 1080p ratio of roughly 0.6 (59/99 at Low, 46/77 at Medium, 34/58 at High, 33/55 at Ultra) is consistent with the 4x pixel count increase of 4K over 1080p, but the fact that the ratio is not exactly 0.25 indicates that some overhead (CPU, memory bandwidth) is shared, and the GPU's efficiency at lower resolutions is better utilized.

# How This Combo Ranks — use comboRankInGame vs other tested combos

The combo of the AMD Ryzen 9 8945HX and AMD Radeon 8050S ranks 2184 out of 2996 tested combos in Microsoft Flight Simulator. This places it in the lower-middle portion of the overall distribution, at roughly the 73rd percentile of all tested configurations (calculated as 1 - 2184/2996). The rank reflects that this combo is not a top-tier performer for this specific game, despite the individual components having respectable benchmark scores.

The CPU's percentile vs all CPUs is 95, meaning it outperforms 95% of processors in general benchmarks. The GPU's percentile vs all GPUs is 89, indicating it beats 89% of graphics cards in synthetic tests. However, the combo rank of 2184 out of 2996 shows that the pairing does not translate to top-tier Flight Simulator performance. This discrepancy suggests that the game's specific workload — which is heavily dependent on single-thread CPU performance for simulation logic and GPU rasterization for terrain rendering — does not fully leverage the strengths of either component.

The CPU's nearest rivals (Intel Core Ultra 9 285HX, AMD EPYC Embedded 8224P, AMD Ryzen Threadripper PRO 9945WX, AMD Ryzen 9 9950X3D) all have average benchmark scores within 0.6% of the 8945HX, indicating that the processor is competitive in general compute. The GPU's nearest rivals (AMD Radeon Pro W6600M with 0.3% delta, AMD Radeon Pro Vega 56 at -2.5%, AMD Radeon RX 7600M at -2.6%, AMD Radeon RX 9060 XT LP at -2.7%) show that the 8050S is slightly above the W6600M but below the Pro Vega 56 and RX 7600M in average GPU benchmark scores. The combo rank of 2184 suggests that in Flight Simulator, the GPU's performance class is the limiting factor — the 8050S's 11.47 TFLOPS is modest for a game that stresses pixel throughput at high resolutions.

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

The AMD Radeon 8050S is an integrated graphics processor (IGP) based on the RDNA 3.5 architecture, built on a 4 nm TSMC process with a die size of 308 mm². It has 2048 shading units, 128 texture mapping units, and 64 render output units, along with 32 ray tracing cores. The GPU operates at a base clock of 1295 MHz and boosts to 2800 MHz, with a TDP of 55 W shared with the CPU package. Memory is system shared, meaning the GPU uses the same DDR5 memory as the CPU, with bandwidth described as "system dependent."

The GPU's memory configuration is notable: it has no dedicated VRAM, relying on shared system memory. In Flight Simulator, which can consume significant memory for terrain textures and object data, this shared memory arrangement can introduce latency and bandwidth contention. The CPU's dual-channel DDR5 interface provides 83.2 GB/s of bandwidth, but that is shared between CPU and GPU workloads. The measured FPS data shows that at 4K Ultra, the combo achieves only 33 FPS average, which is the lowest measured result. This is consistent with the GPU's limited fill rate — 179.2 GPixel/s — being insufficient for 8.29 million pixels per frame at high settings.

The GPU's FP32 performance of 11.47 TFLOPS (with FP16 at 1:1 ratio) is moderate by current standards. Its Geekbench OpenCL score is 65818 and Vulkan score is 58398, placing it in the 89th percentile of all GPUs. Its nearest rival, the AMD Radeon Pro W6600M, has an average score of 61896 (deltaPct 0.3), meaning the 8050S is just 0.3% faster. The Radeon Pro Vega 56 (63693, -2.5%) and RX 7600M (63775, -2.6%) are slightly faster, while the RX 9060 XT LP (63830, -2.7%) leads the group. These small deltas indicate that the 8050S is competitive with mid-range mobile GPUs but sits below the upper tier.

The GPU's role in Flight Simulator becomes clear when examining the FPS scaling: at 1080p Low, the GPU can output 99 FPS, but at 4K Ultra, it drops to 33 FPS. The GPU's limited ROPS (64) and texture units (128) are the primary constraints at high resolutions, as the game requires heavy pixel shading for terrain and cloud rendering. The lack of dedicated VRAM means that at 4K, the system must manage large texture sets through shared memory, which could explain why the 4K High (34 FPS) and 4K Ultra (33 FPS) are nearly identical — the GPU is saturating its available memory bandwidth.

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

The measured FPS data provides a complete matrix of performance across three resolutions and four settings presets. At 1920x1080, the combo achieves the following average FPS: Low 99, Medium 77 (min 65, max 88), High 58, and Ultra 55. The 1080p results show a clear progression where each step up in settings costs roughly 20-22 FPS between Low and Medium, then 19 FPS between Medium and High, and only 3 FPS between High and Ultra. This suggests that the Ultra preset at 1080p offers minimal visual benefits over High for a 5% frame rate reduction.

At 2560x1440, the averages are: Low 80, Medium 62 (min 53, max 71), High 47, and Ultra 44. The 1440p results show a similar pattern: 18 FPS drop from Low to Medium, 15 FPS drop from Medium to High, and 3 FPS drop from High to Ultra. The minimum FPS at 1440p Medium (53) is above the 30 FPS playability threshold, but the average is below 60, indicating that 1440p gaming at Medium is playable but not consistently smooth.

At 3840x2160, the averages are: Low 59, Medium 46 (min 39, max 53), High 34, and Ultra 33. The 4K results show the steepest relative drops: 13 FPS from Low to Medium, 12 FPS from Medium to High, and only 1 FPS from High to Ultra. The 4K Ultra average of 33 FPS is marginal for playable flight simulation, where smooth frame pacing is important for cockpit readability and terrain scanning. The 4K High and Ultra results are nearly identical (34 vs 33), indicating that the GPU is fully saturated at these settings, and additional visual features in Ultra do not meaningfully change performance.

The overall trend across all resolutions: Low settings provide the highest frame rates (ranging from 99 at 1080p to 59 at 4K), Medium offers a balanced 40-50% improvement in visual quality over Low with 22-28% frame rate reduction, High further reduces FPS by 25-35% compared to Medium, and Ultra provides only marginal gains over High (1-5% FPS reduction) while adding the heaviest visual load. The data shows that the combo is most capable at 1080p and 1440p with Medium or Low settings, while 4K gaming requires Low settings to maintain frame rates above 50.
