Microsoft Flight Simulator

The AMD Ryzen 9 7900X and AMD Radeon RX 7900 XT combination delivers a robust experience in Microsoft Flight Simulator, with benchmark results indicating a strong balance between processor and graphics capabilities. The measured data shows that this pairing handles the simulation’s demanding workloads effectively, though the balance of responsibility shifts predictably between the CPU and GPU depending on resolution and settings. This analysis breaks down the specific contributions of each component and how their combined performance ranks against other tested configurations.

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

The AMD Ryzen 9 7900X brings substantial processing power to Microsoft Flight Simulator, a title known for its heavy reliance on single-thread performance for flight modeling and physics calculations. This 12-core, 24-thread processor from the 7000 series operates at a base clock of 4.70 GHz and can boost up to 5.60 GHz, built on the Zen 4 architecture using a 5 nm process. The high boost clock is particularly relevant for this simulator, as the game’s engine frequently depends on a few heavily loaded threads for core simulation tasks, and the data suggests this processor is well-equipped to handle those demands.

The processor’s cache hierarchy, which includes 64 MB of shared L3 cache, helps maintain high throughput when the game streams in terrain and aircraft data. Benchmark results show the CPU achieving a 3dmark single-thread score of 1093 and a multicore score of 12536, reflecting strong performance in both lightly-threaded and fully-utilized scenarios. In Microsoft Flight Simulator, this translates to smooth frame pacing even when the simulation is processing complex scenery or dense urban environments. The CPU’s performance relative to other processors is solid, sitting at the 93rd percentile among all CPUs, with its average benchmark score of 50556 placing it within a fraction of a percent of nearest rivals like the Intel Core Ultra 5 235 and AMD Ryzen 9 5900XT.

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

The AMD Radeon RX 7900 XT serves as the graphics powerhouse in this configuration, and its specifications are directly relevant to how Microsoft Flight Simulator renders its expansive, detailed world. The GPU features 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth. This large memory pool is critical for a flight simulator that loads extensive textures for terrain, aircraft, and weather effects, preventing stuttering when the camera moves rapidly across the landscape. The memory operates at 2500 MHz, with an effective speed of 20 Gbps, while the GPU’s game clock is set at 2025 MHz and boost clock reaches 2394 MHz.

The RDNA 3.0 architecture, built on a 5 nm process with 57,700 million transistors, provides substantial compute resources, including 5376 shading units and 192 ROPs. These specifications allow the card to handle the game’s draw calls and post-processing effects across all tested settings. The GPU’s average benchmark score of 38358 places it at the 82nd percentile among all graphics cards, with its passmark g3d score of 29009 indicating strong rasterization performance. In Microsoft Flight Simulator, the GPU’s role becomes more dominant at higher resolutions and quality presets, where the sheer volume of pixels and texture sampling increases. The 20 GB frame buffer ensures that even at 4K with Ultra settings, the card does not run out of memory, allowing for consistent frame delivery.

How This Combo Ranks — use comboRankInGame vs other tested combos

Within the database of tested hardware combinations, this pairing of the Ryzen 9 7900X and RX 7900 XT holds the 348th position out of 1795 total combos tested in Microsoft Flight Simulator. This places the configuration in the top 20% of all tested systems, indicating that it performs better than the vast majority of alternatives. The rank reflects the combined strengths of both components, as the CPU’s strong single-thread performance supports the simulator’s simulation logic while the GPU’s ample memory and compute resources handle the visual rendering.

The data indicates that this combo outperforms many other pairings, though it is not at the very top of the chart. The rank of 348 suggests there are 347 other combinations that achieve higher average frame rates, likely including configurations with more recent or higher-tier components. However, for users with this specific CPU and GPU, the results show a well-rounded system capable of delivering high frame rates across all tested scenarios. The fact that this is a measured result, not an estimate, adds confidence to the ranking, confirming that these two components work effectively together in this specific title.

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

The measured FPS data reveals a clear performance tiering across resolutions and quality settings. At 1920x1080, the combo delivers its highest frame rates, starting with 179.7 FPS on Low settings. Moving to Medium settings drops the average to 140.5 FPS, while High settings produce 102.1 FPS. The most demanding preset, Ultra, still yields a playable 97.5 FPS, showing that the system can handle 1080p gaming with ease across the entire quality spectrum.

At 2560x1440, the frame rates remain strong but show the expected impact of increased pixel count. Low settings deliver 141.6 FPS, which is still exceptionally high. Medium settings achieve 109.9 FPS, while High settings produce 82.2 FPS. Ultra settings at this resolution result in 79.3 FPS, indicating that the system maintains smooth performance even at the highest quality preset. Moving to 3840x2160, the demands on the GPU become more pronounced. Low settings yield 102.1 FPS, which is identical to the 1080p High result, highlighting the GPU’s headroom. Medium settings produce 79.2 FPS, while High settings drop to 63.2 FPS. Ultra settings at 4K result in 59.3 FPS, which is just below the 60 FPS threshold but still playable for a simulation title.

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

Analyzing the frame rate scaling from 1080p to 4K provides insight into which component is the primary bottleneck at different settings. At Low settings, the frame rate drops from 179.7 FPS at 1080p to 141.6 FPS at 1440p, and then to 102.1 FPS at 4K. This represents a 43.2% reduction from 1080p to 4K, which is a relatively modest drop. This pattern indicates that at Low settings, the CPU is likely the limiting factor, as the GPU has enough headroom to render frames quickly, but the processor’s simulation calculations cap the maximum achievable frame rate.

At High settings, the scaling is steeper: 102.1 FPS at 1080p drops to 82.2 FPS at 1440p and then to 63.2 FPS at 4K, a 38.1% reduction from 1080p to 4K. This suggests that as settings increase, the GPU becomes more heavily utilized, and the frame rate is increasingly constrained by graphics processing rather than CPU simulation. The Ultra settings show the most pronounced scaling, with 97.5 FPS at 1080p falling to 79.3 FPS at 1440p and 59.3 FPS at 4K, a 39.2% drop. The fact that the 1080p Ultra frame rate (97.5 FPS) is only slightly lower than the 1080p High frame rate (102.1 FPS) indicates that the CPU is still keeping pace, but the GPU is starting to become the limiting factor at higher quality presets.

The data reveals that this combo is well-balanced, with the CPU handling simulation tasks efficiently and the GPU providing sufficient rendering power. The relatively flat scaling from 1440p to 4K at Ultra settings (79.3 to 59.3 FPS) suggests that the GPU is nearing its limits at the highest resolution, while the CPU continues to feed it enough data to avoid becoming a bottleneck. This balance makes the configuration versatile, capable of high-refresh-rate play at 1080p and still delivering playable frame rates at 4K with adjusted settings.
