Microsoft Flight Simulator

The AMD Ryzen 7 5800X paired with the AMD Radeon RX 6750 XT delivers a playable, though not flawless, Microsoft Flight Simulator experience that scales predictably with both resolution and graphical fidelity. The data indicates that this combination is firmly mid-pack, sitting at rank 863 out of 1795 tested combos, which places it in the 48th percentile of all systems. The measured frame rates reveal a system that can handle the simulator well at 1080p, remains viable at 1440p, and begins to struggle at 4K when settings are pushed to their limits.

Resolution Scaling

The frame rate progression from 1080p to 4K shows a clear and expected decline, but the magnitude of that drop is telling. At High settings, the system delivers 76.2 FPS at 1920x1080, which falls to 57.9 FPS at 2560x1440, and finally to 42.1 FPS at 3840x2160. This represents a 24% reduction going from 1080p to 1440p, and a further 27% reduction when moving to 4K. The scaling pattern suggests that the GPU is becoming the primary limiting factor as pixel count increases, with the RX 6750 XT's 12 GB of GDDR6 memory and 432.0 GB/s bandwidth being pushed harder at higher resolutions.

The Low settings preset tells a different story. At 1080p Low, the system achieves 128.8 FPS, which is more than 1.5 times the High preset performance at the same resolution. This jumps to 98.8 FPS at 1440p Low and 73.8 FPS at 4K Low. The fact that 4K Low (73.8 FPS) outperforms 1080p High (76.2 FPS) by a narrow margin indicates that the CPU has sufficient headroom, and the bottleneck shifts almost entirely to the GPU when visual complexity increases. The gap between Low and Ultra settings at 4K is particularly stark: 73.8 FPS versus 41.1 FPS, a 44% performance penalty for the highest quality preset.

How This Combo Ranks

Within the database of 1795 tested CPU-GPU combinations for Microsoft Flight Simulator, this pairing achieves rank 863. This position places it just below the median, which aligns with the component specifications: the Ryzen 7 5800X has an 84th percentile ranking among all CPUs, while the RX 6750 XT sits at the 79th percentile among all GPUs. The combination of two above-average components results in a system that is competent but not exceptional for this particular title, which is known for being demanding on both processor and graphics hardware.

The CPU's nearest rivals in synthetic benchmarks provide context for its performance. The AMD Ryzen 7 5800 scores 0.3% higher on average, while the AMD Ryzen 5 8500GE and Intel Core i7-13700H both score 0.4% higher. The Intel Core i5-12600KF leads the group with a 0.8% advantage. These margins are extremely tight, indicating that the 5800X is well within the expected performance envelope for its class. For the GPU, the AMD Radeon RX 5600M trails by just 0.2%, while the NVIDIA GeForce RTX 5070 Ti Mobile is 0.3% ahead, and the AMD Radeon 880M is 0.9% ahead. The NVIDIA GeForce RTX 3080 holds a 1.3% lead over the RX 6750 XT.

CPU Role

The Ryzen 7 5800X brings eight cores and sixteen threads to the flight simulator, running on the Zen 3 architecture with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. This processor has a 32 MB L3 cache and supports dual-channel DDR4 memory with 51.2 GB/s bandwidth. The synthetic benchmarks show strong multi-threaded performance, with a Cinebench R23 multi-core score of 23571 and a single-core score of 3327. The 3DMark results across different thread counts reveal scaling efficiency: 1846 with 2 threads, 3543 with 4 threads, 6035 with 8 threads, and 7586 with 16 threads.

Microsoft Flight Simulator's engine benefits from both strong single-thread performance for the main simulation loop and multi-threaded capabilities for scenery generation and physics. The 5800X's single-thread score of 943 in 3DMark and 2194 in Geekbench single-core suggest it can handle the game's primary thread adequately. The PassMark multi-thread score of 27732 and data compression score of 345414 indicate that background tasks, such as loading terrain and aircraft models, will proceed without creating noticeable stutter. The 7 nm process node and 4,150 million transistors contribute to efficient power usage, though the 105 W TDP means adequate cooling is necessary for sustained boost clocks.

Measured FPS Breakdown

At 1920x1080, the system offers smooth performance across all presets. The Low preset achieves 128.8 FPS, Medium reaches 96.1 FPS, High produces 76.2 FPS, and Ultra delivers 71.5 FPS. All of these figures are above the 60 FPS threshold for a fluid experience, and even the most demanding Ultra preset maintains playability. The difference between High and Ultra at 1080p is only 4.7 FPS, suggesting diminishing returns from the highest quality settings at this resolution.

Moving to 2560x1440, the frame rates remain respectable but show more variation. The Low preset delivers 98.8 FPS, which is still excellent for a flight simulator. Medium drops to 76.8 FPS, High to 57.9 FPS, and Ultra to 58.8 FPS. Interestingly, Ultra actually outperforms High by nearly 1 FPS at this resolution, which could indicate measurement variance or that the game's Ultra preset optimizes certain draw calls differently. The 1440p results place the system in a territory where High and Ultra settings are borderline for 60 FPS displays, while Medium and Low provide comfortable margins.

At 3840x2160, the limitations of the RX 6750 XT become apparent. Low settings yield 73.8 FPS, which is playable, but Medium drops to exactly 60 FPS, High to 42.1 FPS, and Ultra to 41.1 FPS. The 4K Ultra result is below the 60 FPS target by a significant margin, and even High settings fall short. The data suggests that 4K gaming with this combination requires either the Medium preset or careful manual tuning of individual settings to maintain smooth frame rates.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, using a 7 nm process from TSMC with 17,200 million transistors. It features 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of bandwidth. The GPU has 2560 shading units, 160 texture mapping units, and 64 render output units, with 40 ray tracing cores. Its boost clock reaches 2600 MHz, with a game clock of 2495 MHz and base clock of 2150 MHz.

The GPU's synthetic benchmarks reveal its performance class. The PassMark G3D score of 20700 places it in the 79th percentile of all GPUs, while the Geekbench Vulkan score of 109310 and OpenCL score of 107621 show strong compute capabilities. The 3DMark Steel Nomad DX12 score of 2548 indicates modern API performance. The 13.31 TFLOPS FP32 throughput and 416.0 GTexel/s texture rate support the frame rates observed in the flight simulator.

The memory configuration is particularly relevant for Microsoft Flight Simulator, which streams vast amounts of terrain data. The 12 GB VRAM capacity and 432.0 GB/s bandwidth allow the GPU to hold substantial texture and geometry data, which explains why the Low preset at 4K (73.8 FPS) remains playable while Ultra (41.1 FPS) does not. The game clock of 2495 MHz and boost of 2600 MHz provide the raw compute needed for the simulator's lighting and shadow calculations, but the measured results show that the GPU reaches its limits when pixel fill requirements increase at 4K resolution. The 64 ROPs and 166.4 GPixel/s pixel rate become the constraining factor at higher resolutions, as evidenced by the steep drop-off from 1440p to 4K at High settings (57.9 to 42.1 FPS).
