Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 9 5950X and AMD Radeon RX 5700 XT show a clear pattern of GPU-bound scaling as resolution increases. At 1920x1080 with High settings, the combo delivers 56.8 FPS average. Moving to 2560x1440 at the same settings drops that to 48.8 FPS, a reduction of roughly 14%. At 3840x2160 High, the average falls to 33.2 FPS, which is 42% lower than the 1080p result. This progressive decline is typical of a system where the graphics card becomes the primary bottleneck as pixel count rises.

The Low settings curve tells a similar story but with higher absolute numbers. At 1080p Low, the system reaches 100.4 FPS average — the only triple-digit result in the entire dataset. At 1440p Low, that drops to 77.1 FPS, and at 4K Low it reaches 58.3 FPS. The gap between 1080p Low and 4K Low is 42.1 FPS, or roughly 42% — nearly identical to the High-settings scaling penalty. This consistency across settings levels suggests the resolution scaling behavior is driven by the GPU's fill rate and memory bandwidth rather than by specific rendering features.

Medium and Ultra settings follow the same trajectory. Medium yields 78.6 FPS at 1080p, 60.2 FPS at 1440p, and 43.7 FPS at 4K. Ultra produces 55.5 FPS at 1080p, 46.3 FPS at 1440p, and 30.6 FPS at 4K. The Ultra 4K result of 30.6 FPS is notably below the 60 FPS target that many flight sim enthusiasts prefer, indicating that this combination is not suited for maximum-fidelity 4K play in Microsoft Flight Simulator.

The data indicates that the RX 5700 XT is the limiting component at 4K across all settings. Even at Low settings, the 4K result of 58.3 FPS is only slightly above the 1440p High result of 48.8 FPS, showing that the GPU is saturated by raw pixel throughput. At 1080p, the CPU still has headroom — the jump from 56.8 FPS at High to 100.4 FPS at Low shows that reducing graphics load can substantially raise frame rates, meaning the CPU is not the primary constraint at that resolution.

GPU Role

The AMD Radeon RX 5700 XT is built on the Navi 10 chip using RDNA 1.0 architecture, produced on TSMC's 7 nm process with 10,300 million transistors on a 251 mm² die. Its memory subsystem consists of 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The GPU's base clock is 1605 MHz, with a game clock of 1755 MHz and a boost clock of 1905 MHz. Memory runs at 1750 MHz, which translates to 14 Gbps effective.

In Microsoft Flight Simulator, the 8 GB VRAM capacity is a relevant factor. The game is known for streaming large textures and terrain data, and the measured results suggest the memory configuration is adequate at 1080p and 1440p across all settings. At 4K Ultra, the 30.6 FPS average indicates the GPU is struggling with both compute load and memory pressure. The 448.0 GB/s bandwidth is sufficient for 1080p and 1440p workloads, but the 4K results show that higher resolutions demand more from the memory subsystem than the card can provide.

The GPU's benchmark percentile of 68 versus all GPUs places it in the upper-middle tier. Its average benchmark score of 24731 puts it near the NVIDIA RTX A5000 Mobile (24763, deltaPct -0.1) and just ahead of the Intel Arc A350M (24647, deltaPct 0.3) and NVIDIA GeForce RTX 5060 Mobile (24592, deltaPct 0.6). The NVIDIA Quadro RTX 5000 trails slightly at 24519 (deltaPct 0.9). These close benchmark scores suggest the RX 5700 XT competes with those mobile and workstation parts in synthetic tests, though the Flight Simulator results show its real-world behavior is heavily dependent on resolution and settings.

The pixel rate of 121.9 GPixel/s and texture rate of 304.8 GTexel/s are the kind of specifications that influence how well the card handles the dense geometry and high-resolution textures in a flight sim. The FP32 throughput of 9.754 TFLOPS gives an indication of raw compute capability, but the game's rendering engine appears more sensitive to memory bandwidth and fill rate, as evidenced by the steep 4K scaling curves.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on Zen 3 architecture (codename Vermeer), built on TSMC's 7 nm process with 8,300 million transistors across two 74 mm² dies. It operates at a base clock of 3.40 GHz and boosts up to 4.90 GHz. The CPU has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 64 MB of L3 cache. It supports dual-channel DDR4 memory with 51.2 GB/s of bandwidth.

In Microsoft Flight Simulator, the CPU handles simulation logic, physics, and AI traffic — tasks that can be heavily multithreaded. The 5950X's 16 cores and 32 threads provide substantial headroom for these workloads. Its Cinebench R23 multicore score of 38607 and single-core score of 5450 demonstrate strong performance in both heavily threaded and lightly threaded scenarios. The 3DMark max-threads score of 11597 and single-thread score of 944 reinforce this picture.

The CPU's percentile versus all CPUs is 93, indicating it outperforms the vast majority of processors. Its average benchmark score of 49062 places it close to the Intel Core i5-14600K (49166, deltaPct -0.2) and Intel Core i5-14600KF (49367, deltaPct -0.6). The AMD EPYC 4345P scores 49595 (deltaPct -1.1) and the Intel Xeon Gold 5318H scores 48698 (deltaPct 0.7). These rival comparisons show the 5950X is competitive with modern mid-range and high-end parts in synthetic benchmarks.

In the measured Flight Simulator results, the CPU's influence is most apparent at 1080p Low, where the system reaches 100.4 FPS. This high frame rate indicates the CPU can feed the GPU effectively at lower graphics loads. At 1080p Ultra, the drop to 55.5 FPS shows the GPU becoming the limiting factor. The fact that 1440p Low (77.1 FPS) is lower than 1080p Low (100.4 FPS) but 1440p Ultra (46.3 FPS) is close to 1080p Ultra (55.5 FPS) suggests the CPU maintains adequate performance across resolutions when the GPU is not saturated.

How This Combo Ranks

The AMD Ryzen 9 5950X + AMD Radeon RX 5700 XT combination ranks 1370 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the lower-middle portion of the database, which is somewhat surprising given the CPU's high percentile ranking. The rank reflects the GPU's limitations as the primary bottleneck in this pairing.

The combo's position relative to other tested configurations is driven almost entirely by the RX 5700 XT's performance tier. The GPU's 68th percentile ranking versus all GPUs, combined with the CPU's 93rd percentile, creates an imbalance where the graphics card holds back the system's overall gaming performance. A more balanced pairing would likely have a GPU with higher relative standing to match the CPU's capabilities.

The rank of 1370 out of 1795 means that approximately 425 combos tested slower than this one in Flight Simulator. This places the combo in the 76th percentile of tested configurations, meaning it outperforms about three-quarters of the database entries. However, for a system built around a 16-core flagship CPU, the gaming results are modest, reflecting the GPU's mid-range positioning rather than the CPU's high-end status.

Measured FPS Breakdown

At 1920x1080, the combo produces its best results. Low settings yield 100.4 FPS average, Medium reaches 78.6 FPS, High drops to 56.8 FPS, and Ultra settles at 55.5 FPS. The gap between Low and Ultra is 44.9 FPS, showing that settings have a significant impact at this resolution. The small difference between High (56.8 FPS) and Ultra (55.5 FPS) — just 1.3 FPS — indicates diminishing returns from the highest quality preset.

At 2560x1440, the averages are 77.1 FPS for Low, 60.2 FPS for Medium, 48.8 FPS for High, and 46.3 FPS for Ultra. The 1440p results show a compression of the performance envelope compared to 1080p. The Low-to-Ultra spread is 30.8 FPS, narrower than at 1080p. The High-to-Ultra delta at 1440p is 2.5 FPS, still small but slightly larger than at 1080p.

At 3840x2160, the results are 58.3 FPS for Low, 43.7 FPS for Medium, 33.2 FPS for High, and 30.6 FPS for Ultra. The 4K Low result of 58.3 FPS is the only 4K setting that approaches playable smoothness for most users. The Ultra result of 30.6 FPS is below the 30 FPS threshold that some consider the minimum for simulation games, though it technically clears it by 0.6 FPS. The Low-to-Ultra spread at 4K is 27.7 FPS, further compressing as resolution increases.

The data shows a consistent pattern: settings have the largest impact at 1080p and the smallest at 4K. This indicates that at 4K, the GPU is so heavily loaded that even reducing settings to Low cannot fully compensate for the pixel throughput demands. The 1080p Low result of 100.4 FPS is the only time this combo breaks the 100 FPS barrier, and it remains the standout figure in the measured dataset.
