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

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor built on the Zen 3 architecture (Vermeer) using TSMC's 7 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 4.90 GHz, drawing a 105 W TDP. The chip features 64 KB of L1 cache per core, 512 KB of L2 per core, and a substantial 64 MB of L3 cache. Memory support is dual-channel DDR4 with a bandwidth of 51.2 GB/s, and the CPU connects via PCIe Gen 4 with 20 lanes.

In synthetic benchmarks, the 5950X demonstrates strong multi-threaded capability. It scores 26,017 in Cinebench R23 multi-core and 1,614 in single-core, while Geekbench results show 15,233 multi-core and 2,083 single-core. The 3DMark tests reveal scaling from 944 points in single-thread to 11,597 at max threads, indicating the processor effectively utilizes its 16 cores. The PassMark multi-thread score of 45,424 and single-thread of 3,470 place this CPU in the 91st percentile among all processors.

For Microsoft Flight Simulator, the CPU's role is significant but not necessarily the primary constraint in this pairing. The game is known to be heavily dependent on single-thread performance for its simulation logic, and the 5950X's single-core scores are respectable. However, the measured FPS data shows that at 1080p Low settings, the system achieves 48 FPS average, which is the highest result across all configurations. This suggests that at lower resolutions and settings, the CPU is capable of feeding the GPU adequately, but the overall frame rates are limited by other factors.

The nearest rival comparison shows the 5950X is closely matched with the Intel Core Ultra 5 235HX (delta -0.2%), AMD EPYC 8124P (delta -0.3%), Intel Core i9-13900F (delta +0.4%), and Intel Core i7-14700 (delta -0.7%). This indicates that the 5950X sits in a competitive performance tier, though the differences are marginal. In the context of this game, the CPU's 16 cores provide headroom for background tasks and the simulation's multi-threaded aspects, but the single-thread performance is what matters most for the core flight model calculations.

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

The AMD Radeon RX 570 is built on the Polaris 20 chip using GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It features 4 GB of GDDR5 memory on a 256-bit bus, providing 224.0 GB/s of bandwidth. The GPU operates with a base clock of 1168 MHz and a boost clock of 1244 MHz, with memory running at 1750 MHz (7 Gbps effective). The card has 2,048 shading units, 128 TMUs, and 32 ROPs, delivering 5.095 TFLOPS of FP32 performance.

The RX 570's memory configuration is particularly relevant for Microsoft Flight Simulator at higher resolutions. The game's detailed terrain and aircraft models can consume significant VRAM, and the 4 GB capacity may become a limiting factor. The benchmark results show a clear pattern: at 4K Ultra settings, the average FPS drops to 16, while at 1080p Low, it reaches 48 FPS. This scaling suggests that the GPU's compute capability and memory bandwidth are being saturated as resolution and quality increase.

In GPU benchmarks, the RX 570 scores 880 in 3DMark Steel Nomad DX12, 39,349 in Geekbench Metal, 32,084 in OpenCL, and 42,752 in Vulkan. These results place it in the 74th percentile among all GPUs. The nearest rivals include the AMD Radeon RX 6800M (delta -0.4%), AMD Radeon R9 M295X (delta +0.7%), AMD Radeon RX 470 (delta -0.8%), and NVIDIA Quadro RTX 8000 (delta +1.2%). The RX 570's average benchmark score of 28,766 is close to these competitors, indicating it performs in a similar tier.

The GPU's 150 W TDP and 450 W suggested PSU requirement are modest, but the card's age (released in April 2017) means it lacks modern features like ray tracing acceleration. For this flight simulator, the RX 570's role is clearly the primary bottleneck at higher settings. The data shows that even at 1080p High, the average FPS is only 28, which is below the threshold for smooth gameplay. The GPU's 4 GB VRAM likely causes texture thrashing and reduced performance when the game attempts to load high-resolution assets.

# How This Combo Ranks

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 570 ranks 3,538 out of 3,714 tested combos in Microsoft Flight Simulator. This places the system in the bottom 5% of all tested configurations, indicating a significant mismatch between the CPU's high-end positioning and the GPU's mid-range capability.

The CPU alone ranks in the 91st percentile among all processors, with an average benchmark score of 51,947. Its nearest rivals include the Intel Core Ultra 5 235HX (52,073, -0.2%), AMD EPYC 8124P (52,121, -0.3%), Intel Core i9-13900F (51,730, +0.4%), and Intel Core i7-14700 (52,301, -0.7%). These close margins show the 5950X is competitive with modern high-end processors.

The GPU ranks in the 74th percentile among all graphics cards, with an average benchmark score of 28,766. Its nearest rivals are all within 1.2% of its score, showing the RX 570 is a mid-tier performer that has aged but remains competitive with its immediate peers.

The low combo ranking is primarily attributable to the GPU's limitations in this specific game. Microsoft Flight Simulator is graphically demanding, and the RX 570's 4 GB VRAM and 5.095 TFLOPS of compute power are insufficient for the game's high-resolution textures and complex rendering. The measured FPS data confirms this: the system never exceeds 48 FPS even at the lowest settings, and at 1080p Ultra, it manages only 27 FPS average.

This combination represents a classic bottleneck scenario where a high-end CPU is paired with a budget GPU. The 5950X has ample processing power for the game's simulation logic, but the RX 570 cannot translate that CPU capability into high frame rates due to its graphics limitations.

# Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality presets. At 1080p, the system achieves its best results:

• 1080p Low: 48 FPS average
• 1080p Medium: 38 FPS average (min 32, max 43)
• 1080p High: 28 FPS average
• 1080p Ultra: 27 FPS average

Moving to 1440p shows a consistent performance drop:

• 1440p Low: 39 FPS average
• 1440p Medium: 30 FPS average (min 26, max 35)
• 1440p High: 23 FPS average
• 1440p Ultra: 22 FPS average

At 4K, the system struggles to maintain playable frame rates:

• 4K Low: 29 FPS average
• 4K Medium: 22 FPS average (min 19, max 26)
• 4K High: 17 FPS average
• 4K Ultra: 16 FPS average

The data reveals several patterns. First, the difference between High and Ultra settings is minimal at every resolution. At 1080p, High yields 28 FPS and Ultra yields 27 FPS; at 1440p, the difference is 23 vs 22 FPS; at 4K, it is 17 vs 16 FPS. This suggests that the Ultra preset adds minimal visual fidelity while providing negligible performance impact, likely because the GPU is already saturated.

Second, the performance drop from Low to Medium is substantial. At 1080p, Low achieves 48 FPS while Medium drops to 38 FPS, a 10 FPS reduction. This indicates that the Medium preset introduces significant GPU workload increases, possibly through higher texture quality or more complex lighting calculations.

Third, the scaling from 1080p to 1440p is roughly linear. At Low settings, the drop is from 48 to 39 FPS (about 19% reduction); at Medium, from 38 to 30 FPS (21% reduction); at High, from 28 to 23 FPS (18% reduction); at Ultra, from 27 to 22 FPS (19% reduction). This consistent scaling suggests that the GPU is the limiting factor across all settings.

# Settings Recommendations

Based on the measured FPS data, the optimal configuration for this combo is 1080p with Low settings, which delivers 48 FPS average. This is the only setting that approaches a smooth experience, though it still falls below the 60 FPS target that many players prefer.

For players who prioritize visual quality over frame rate, 1080p Medium offers a compromise at 38 FPS average, with a minimum of 32 FPS and maximum of 43 FPS. This provides a more detailed image while maintaining playable performance in most scenarios. The Medium preset's minimum FPS of 32 indicates that the system can maintain a playable frame rate even during demanding scenes.

High settings at 1080p yield 28 FPS average, which is borderline playable but may result in noticeable stuttering during complex scenes. Ultra settings at 1080p provide 27 FPS average, offering negligible visual improvements over High while maintaining similar performance.

At 1440p, Low settings achieve 39 FPS, which is playable but not ideal. Medium settings at 1440p drop to 30 FPS, which is marginal. High and Ultra at 1440p produce 23 and 22 FPS respectively, which are below the threshold for smooth gameplay.

The 4K resolution is not recommended for this combination. Even at Low settings, the system only achieves 29 FPS average, and at Ultra, it drops to 16 FPS. The performance at 4K is consistently below playable levels.

The data suggests that players should use 1080p Low for the best experience, with the option to increase to Medium if they can tolerate lower frame rates for improved visuals. The High and Ultra presets offer no meaningful advantage over Medium at 1080p, given the marginal FPS differences.

# Resolution Scaling

The FPS drop from 1080p to 4K is significant and revealing. At Low settings, performance falls from 48 FPS at 1080p to 39 FPS at 1440p and 29 FPS at 4K. This represents a 19% reduction from 1080p to 1440p, and a 40% reduction from 1080p to 4K.

At Medium settings, the scaling is similar: 38 FPS at 1080p, 30 FPS at 1440p, and 22 FPS at 4K. This is a 21% drop from 1080p to 1440p and a 42% drop from 1080p to 4K.

High settings show 28 FPS at 1080p, 23 FPS at 1440p, and 17 FPS at 4K — reductions of 18% and 39% respectively. Ultra settings follow the same pattern: 27 FPS at 1080p, 22 FPS at 1440p, and 16 FPS at 4K — reductions of 19% and 41%.

The consistent scaling across all settings indicates that the GPU is the limiting component. If the CPU were the bottleneck, the FPS would remain relatively constant across resolutions, as the CPU workload does not change significantly with resolution. Instead, the linear FPS reduction with increasing resolution is a classic sign of GPU saturation.

The RX 570's 4 GB VRAM and 224.0 GB/s bandwidth are likely contributing to this scaling. At 4K, the game requires significantly more memory bandwidth and capacity to handle high-resolution textures. The GPU's 5.095 TFLOPS of compute power also becomes a limiting factor as pixel count increases.

The data suggests that this combination is best suited for 1080p gaming. The CPU's strong single-thread performance ensures that the simulation logic runs smoothly, but the GPU cannot keep up with higher resolutions. Players seeking higher resolutions would need a more powerful graphics card to unlock the 5950X's full potential in this game.
