Microsoft Flight Simulator

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 580 presents a stark contrast in Microsoft Flight Simulator: a flagship 16-core processor harnessed to an entry-level 2017 graphics card. The benchmark data reveals a system where the GPU is the definitive bottleneck, and the results are consistently constrained by the Radeon's capabilities regardless of the processor's immense headroom.

Resolution Scaling

The frame rate scaling across resolutions is a textbook demonstration of GPU-bound performance. At 1080p with Low settings, the combo achieves 55.1 FPS, but this figure drops precipitously as resolution increases. Moving to 1440p Low yields 41.7 FPS, a 24% reduction, and 4K Low produces 29.5 FPS, a further 29% drop from 1440p. This steep decline with pixel count is the signature of a graphics card operating at its absolute limit, where the fill rate and memory bandwidth of the RX 580 are overwhelmed.

The pattern holds across all quality presets. For High settings, the progression is 33.8 FPS at 1080p, 23.8 FPS at 1440p, and 17.5 FPS at 4K. The delta between 1080p and 4K at High is a 48% loss in performance. This non-linear scaling indicates that the GPU's 256-bit memory bus and 256.0 GB/s bandwidth are saturated, and the 8 GB of GDDR5 memory, while adequate in capacity, cannot deliver the data throughput required for 4K textures in this simulation.

What is particularly telling is the relationship between quality settings at each resolution. At 1080p, the jump from Low (55.1 FPS) to Medium (43.5 FPS) is a 21% performance hit, while the jump from Medium to High (33.8 FPS) is a 22% hit. However, the difference between High and Ultra (27.9 FPS) is only 17%. This compression of the performance gap at the top end suggests that the game's Ultra preset introduces effects that are heavily dependent on shader complexity, which the RX 580's GCN 4.0 architecture handles poorly, but the core limitation remains the pixel throughput. The data shows that this processor has no influence on the scaling; the Ryzen 9 5950X is never the limiting factor, as evidenced by the consistent FPS degradation purely tied to GPU workload.

How This Combo Ranks

In the grand database of tested combinations, this pairing ranks 1658 out of 1795 combos for Microsoft Flight Simulator. This places it in the bottom 8% of all systems tested, a position that aligns perfectly with the GPU's modest standing. The RX 580 sits at the 53rd percentile among all GPUs, and its average benchmark score of 13559 puts it in direct competition with the NVIDIA GeForce GTX 570 (score 13564, delta 0%) and the NVIDIA GeForce GTX 950 (score 13549, delta 0.1%). This is not a component designed for modern high-fidelity simulation.

The CPU, by contrast, is a top-tier part. The Ryzen 9 5950X sits at the 93rd percentile among all CPUs, with an average benchmark score of 49062. Its nearest rival is the Intel Core i5-14600K (score 49166, delta -0.2%), indicating the AMD chip is effectively neck-and-neck with a modern mid-range Intel offering. Yet, this massive CPU potential is completely wasted in this configuration. The combo rank of 1658 is a direct consequence of the GPU's limitations, proving that in this specific title, the pairing's overall capability is dictated entirely by the weakest link. The deltaPct values for the CPU's rivals show a spread of less than 2%, confirming the 5950X is a high-performing part that is being held back.

GPU Role

The AMD Radeon RX 580 is the sole arbiter of this system's gaming performance. Its specifications—2304 shading units, 144 texture mapping units, and 32 ROPs—are from the GCN 4.0 architecture, a design that predates the game's 2020 release. The GPU's boost clock of 1340 MHz and base clock of 1257 MHz are low by modern standards, and its 6.175 TFLOPS of FP32 compute is modest.

Crucially, the RX 580 has no dedicated ray tracing cores and no tensor cores. Microsoft Flight Simulator's rendering pipeline, while not requiring ray tracing, is heavily dependent on raw geometric and texture throughput. The data indicates the GPU's 42.88 GPixel/s pixel rate and 193.0 GTexel/s texture rate are insufficient for the game's complex scenery rendering at higher resolutions. The 8 GB of GDDR5 memory with 256.0 GB/s bandwidth is a further limitation; at 4K Ultra, the average FPS is 17.4, which is effectively unplayable.

The GPU's benchmark scores reinforce this. Its 3DMark Steel Nomad DX12 score is 1005, and its Passmark G3D score is 8813. These figures place it at the 53rd percentile, directly alongside the GTX 570 and GTX 950. The GPU's G2D score of 769 is also low, indicating weak 2D acceleration that can impact UI rendering in a dense simulator interface. The data shows a component that was mid-range in 2017 and is now firmly in the entry-level category for a 2020 simulation title.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's capabilities across all settings. At 1080p, the only resolution that approaches playability, the results are: Low 55.1 FPS, Medium 43.5 FPS, High 33.8 FPS, and Ultra 27.9 FPS. The Low setting is the only one that achieves a consistent 60Hz experience, while Medium is borderline for a flight simulator where frame pacing is less critical than in a competitive shooter.

At 1440p, the system struggles. The Low preset delivers 41.7 FPS, but Medium drops to 34.9 FPS, High to 23.8 FPS, and Ultra to 26 FPS. The non-monotonic result between High and Ultra (23.8 vs 26) suggests that the Ultra preset may alter certain draw distances or LOD settings in a way that slightly reduces the immediate pixel load in the test scenario, but the overall trend is one of decline. The 1440p results are generally below the threshold for smooth flight simulation, which often requires stable 30 FPS for acceptable visual continuity.

At 4K, the results are uniformly poor. Low yields 29.5 FPS, Medium 26.9 FPS, High 17.5 FPS, and Ultra 17.4 FPS. These figures are all below 30 FPS, making the game feel stuttery and visually jarring. The difference between High and Ultra at 4K is negligible (0.1 FPS), confirming that the GPU is completely saturated and cannot differentiate between these two demanding presets. The data clearly shows that this combo is only viable for 1080p gaming with reduced settings, and any attempt to push higher resolutions will result in a sub-30 FPS experience.

FAQ

Q: Can this system run Microsoft Flight Simulator at 4K?

A: No. The measured FPS at 3840x2160 ranges from 29.5 FPS on Low to 17.4 FPS on Ultra. All 4K presets are below the 30 FPS threshold typically required for smooth flight simulation, rendering the experience visually broken.

Q: What is the best resolution and settings for this combo?

A: The data shows that 1920x1080 with Low settings (55.1 FPS) is the only configuration that provides a consistent 60 FPS experience. For a balance of visuals and playability, 1080p Medium (43.5 FPS) is the most viable option, as it stays above 30 FPS while offering improved detail.

Q: How does the GPU compare to its closest rivals?

A: The RX 580 has an average benchmark score of 13559, placing it directly alongside the NVIDIA GeForce GTX 570 (13564, 0% delta) and the NVIDIA GeForce GTX 950 (13549, 0.1% delta). It is also within 1.1% of the AMD Radeon Pro 455 (13416).

Q: Is the CPU a bottleneck in this game?

A: No. The AMD Ryzen 9 5950X is a high-end processor with a 93rd percentile ranking and an average score of 49062. The FPS scaling across resolutions is entirely consistent with GPU limitations, indicating the RX 580 is the sole bottleneck.

Q: What does the combo rank of 1658 out of 1795 mean?

A: It means this pairing performs worse than approximately 92% of all tested combinations in Microsoft Flight Simulator. This low rank is a direct result of the GPU's performance class, which is at the 53rd percentile, and not the CPU's capability.

Q: Is the 8 GB of VRAM sufficient for this game?

A: The 8 GB capacity is present, but the limiting factor is the 256.0 GB/s bandwidth. The steep FPS drops at 4K, where textures require higher bandwidth, indicate that the memory subsystem cannot feed the GPU fast enough, making the VRAM size a secondary concern to the bandwidth limitation.
