Microsoft Flight Simulator

The AMD Ryzen 5 5600 and AMD Radeon RX 7800 XT combination delivers a robust experience in Microsoft Flight Simulator, positioning itself in the top 37.6% of all tested configurations. The data reveals a system where the GPU becomes the primary scaling factor at higher resolutions, while the CPU provides a solid foundation for lower-resolution high-refresh-rate play.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 145 FPS at 1080p to 116.4 FPS at 1440p, a decline of approximately 19.7%. Pushing further to 4K reduces the average to 84.8 FPS, representing a 41.5% drop from the 1080p baseline. This scaling indicates that at lower resolutions, the system is not entirely GPU-bound, as the frame rate decreases are not proportionate to the pixel count increase.

The Medium settings tell a similar story, with 113.2 FPS at 1080p falling to 93.9 FPS at 1440p (a 17.1% reduction) and then to 64.9 FPS at 4K (a 42.7% reduction from 1080p). The High settings show 84.8 FPS at 1080p, 67 FPS at 1440p, and 48.9 FPS at 4K. The transition from 1440p to 4K consistently produces a larger relative drop than the transition from 1080p to 1440p across all settings, highlighting the increasing pixel throughput demands placed on the RX 7800 XT.

Ultra settings present the most demanding scenario, with 80.8 FPS at 1080p, 68 FPS at 1440p, and 45.5 FPS at 4K. The gap between High and Ultra at 4K is narrow, at just 3.4 FPS, suggesting that the Ultra preset's additional graphical features are heavily constrained by the resolution. The scaling pattern across all settings strongly indicates that at 4K, the AMD Radeon RX 7800 XT's rendering capabilities become the limiting factor, while at 1080p, the Ryzen 5 5600's six-core Zen 3 architecture is sufficient to keep frame rates high.

How This Combo Ranks

Within the benchmark database, this specific combination of CPU and GPU achieves a combo rank of 675 out of 1795 tested configurations in Microsoft Flight Simulator. This places the pairing in the 62.4th percentile of all combos, meaning it outperforms a majority of tested systems. The ranking reflects a balanced pairing where neither component severely bottlenecks the other across the tested settings range.

The CPU itself sits at the 79th percentile among all processors, with an average benchmark score of 21765. Its nearest rivals in synthetic benchmarks include the Intel Xeon D-1746TER, which scores 21635 (0.6% lower), and the AMD EPYC 9554P, which scores 21899 (0.6% higher). This tight clustering around the Ryzen 5 5600's score indicates that its computational throughput is competitive with enterprise-class server chips, though those parts lack the gaming-focused feature set.

The GPU achieves the 76th percentile among all graphics cards, with an average benchmark score of 32619. Its closest competitor, the AMD FirePro S9300 X2, scores 32540 (0.2% lower), while the NVIDIA P104-100 scores 32747 (0.4% higher). The near-identical scores among these rivals suggest that the RX 7800 XT's raw compute performance is well-matched to its peers, yet its combination with the Ryzen 5 5600 yields a combo rank that reflects the specific demands of Flight Simulator's engine.

The discrepancy between the individual component percentiles (79th for CPU, 76th for GPU) and the combo rank percentile (62.4th) indicates that this game is particularly demanding on the entire system, with neither component able to fully compensate for the other's limitations. The data suggests that higher-ranked combos likely feature both stronger CPUs and GPUs, as Flight Simulator's simulation-heavy workload taxes both simultaneously.

GPU Role

The AMD Radeon RX 7800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of memory bandwidth. This generous memory allocation is particularly relevant for Microsoft Flight Simulator, which streams vast amounts of terrain and scenery data. The 3840 shading units and 240 texture mapping units work in concert to handle the game's complex shader workloads, while the 96 render output units manage the final pixel throughput.

The GPU's clock behavior demonstrates a wide operating range, with a base clock of 1295 MHz and a boost clock of 2430 MHz, alongside a game clock of 2124 MHz. The 5 nm process node and RDNA 3.0 architecture allow for efficient power delivery, with the card rated at 263 W TDP. The 60 ray tracing cores provide hardware acceleration for the game's lighting effects, though the measured FPS data suggests that the traditional rasterization pipeline remains the dominant workload.

At 4K Ultra settings, the GPU produces an average of 45.5 FPS, which is 35.1 FPS lower than the 1080p Ultra result of 80.8 FPS. This 43.4% reduction in frame rate at four times the pixel count demonstrates the GPU's scaling limitations. The 16 GB VRAM capacity prevents memory-related stuttering at high resolutions, as evidenced by the stable average FPS figures across all settings without reported minimum frame rate drops.

The GPU's performance in this game is further contextualized by its PassMark G3D score of 24176, which places it in the 76th percentile of all GPUs. The compute capabilities, measured at 13473 in PassMark GPU Compute, suggest that the card has ample headroom for the physics and AI calculations that Flight Simulator offloads to the GPU. The FP32 performance of 37.32 TFLOPS provides substantial raw compute throughput for the game's dynamic weather and flight model simulations.

FAQ

A: The resolution scaling analysis indicates the GPU becomes the primary bottleneck at 3840x2160. The frame rate drops from 145 FPS at 1080p Low to 84.8 FPS at 4K Low, a 41.5% reduction that aligns with the increased pixel workload on the RX 7800 XT.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 145 FPS, representing the peak performance of the pairing. Medium settings achieve 113.2 FPS, while High settings reach 84.8 FPS. Ultra settings yield 80.8 FPS, which is 64.2 FPS lower than Low settings at the same resolution.

Moving to 2560x1440, the performance scales down consistently. Low settings average 116.4 FPS, a 28.6 FPS reduction from 1080p Low. Medium settings produce 93.9 FPS, while High settings achieve 67 FPS. Ultra settings average 68 FPS, which is notably 1 FPS higher than High settings at this resolution, suggesting a minor variance in the Ultra preset's workload at 1440p.

At 3840x2160, the GPU's workload becomes the dominant factor. Low settings deliver 84.8 FPS, which is identical to the 1080p High result, indicating that the Low preset at 4K imposes a similar GPU load to High at 1080p. Medium settings achieve 64.9 FPS, while High settings produce 48.9 FPS. Ultra settings yield 45.5 FPS, the lowest measured result across all configurations.

The progression from 1080p to 4K at each settings level shows a consistent pattern. For Low settings, the frame rate drops by 28.6 FPS going to 1440p and another 31.6 FPS going to 4K. Medium settings lose 19.3 FPS from 1080p to 1440p, then 29 FPS from 1440p to 4K. High settings lose 17.8 FPS to 1440p and 18.1 FPS to 4K. Ultra settings lose 12.8 FPS to 1440p and 22.5 FPS to 4K. These figures demonstrate that higher settings presets show smaller absolute drops at lower resolution steps but larger drops at the 4K step, confirming the GPU's rendering capacity is the primary constraint at 3840x2160.
