Microsoft Flight Simulator

# Microsoft Flight Simulator — AMD Ryzen 7 5800X3D + NVIDIA GeForce RTX 5070 Ti

The benchmark data for this combination shows a system that is heavily GPU-limited at higher resolutions but reveals a strong CPU foundation at 1080p. The measured FPS profile across three resolutions and four quality settings places this pairing in the 157th position out of 1,795 tested combos, placing it in the top 8.8% of all configurations tested for this flight simulator. The RTX 5070 Ti, with its 16 GB of GDDR7 memory and 896.0 GB/s bandwidth, drives the demanding rendering workload, while the Ryzen 7 5800X3D's large 96 MB of shared L3 cache proves sufficient to keep frame rates high even at lower resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals where the bottleneck shifts. At Ultra settings, the average frame rate falls from 112.6 FPS at 1920x1080 to 91.4 FPS at 2560x1440, a reduction of 18.8%. Moving from 1440p to 4K Ultra brings the average down further to 64.9 FPS, another 29.0% decrease. This progressive decline indicates that the GPU becomes the limiting component as pixel count rises, with the 4K Ultra result sitting just above playable thresholds for a simulator.

The scaling pattern is even more pronounced at Low settings. At 1080p Low, the system produces 174 FPS, but at 1440p Low it drops to 161.1 FPS (a 7.4% decline), and at 4K Low it falls to 114.7 FPS (a 28.8% drop from 1440p). The relatively small penalty from 1080p to 1440p at Low settings suggests that the CPU is still contributing meaningfully at 1080p, but the larger 1440p-to-4K gap confirms the GPU's dominance at higher resolutions. At 4K, even Low settings cannot maintain the triple-digit frame rates seen at 1440p.

Comparing High and Medium settings at each resolution shows a consistent pattern: Medium sits roughly 15-20% above High at every resolution, while Ultra sits roughly 20-24% below High. This consistent spacing across resolutions indicates that the settings scaling is predictable and that the GPU workload scales uniformly with quality level.

How This Combo Ranks

The combo rank of 157 out of 1,795 tested configurations places this pairing in the upper echelon of systems tested for Microsoft Flight Simulator. This top 8.8% position reflects a balanced combination where neither component severely limits the other at the most common gaming resolutions. The rank is particularly strong considering the game's reputation as a demanding title that stresses both CPU and GPU heavily.

The CPU's benchmark scores support this ranking. The Ryzen 7 5800X3D achieves a Cinebench R23 multicore score of 24,063 and a single-core score of 3,397, with an average benchmark score of 26,574. Its percentile ranking of 83 among all CPUs places it above most desktop processors. The nearest rivals in CPU performance include the AMD EPYC 8024P (0.1% ahead) and Intel Core i9-11900K (0.1% ahead), as well as the AMD Ryzen 5 7600 (0.2% behind) and Intel Core i9-12900HK (0.4% behind). This tight clustering indicates that the 5800X3D's performance is competitive with newer and higher-core-count alternatives.

The GPU's percentile ranking of 87 among all GPUs, with an average benchmark score of 52,086, is nearly identical to the NVIDIA GeForce RTX 4080 (0.0% delta) and slightly ahead of the AMD Radeon RX 7700S (0.8% ahead) and NVIDIA RTX A1000 (2.5% ahead). This places the RTX 5070 Ti at the top of the GPU hierarchy, with only the AMD Radeon Pro W6600M (2.5% behind) showing a meaningful gap in the other direction.

GPU Role

The NVIDIA GeForce RTX 5070 Ti brings 16 GB of GDDR7 memory across a 256-bit bus, yielding 896.0 GB/s of memory bandwidth. This high bandwidth is critical for a flight simulator that streams terrain and scenery data continuously. The GPU's 8,960 shading units, 280 texture mapping units, and 96 ROPs provide substantial raw compute, with FP32 performance rated at 43.94 TFLOPS. The boost clock of 2,452 MHz, up from a base of 2,295 MHz, allows the GPU to scale dynamically under load.

The 16 GB frame buffer proves adequate for this title, as the measured FPS values show no signs of VRAM-related stuttering or abrupt performance cliffs. At 4K Ultra, the average frame rate of 64.9 FPS suggests the GPU is fully utilized, with the large memory capacity preventing any texture streaming bottlenecks that could otherwise occur in a simulator with extensive photogrammetry data.

The GPU's 3DMark Steel Nomad DX12 score of 6,604 and PassMark G3D score of 32,974 align with its 87th percentile ranking. The Geekbench OpenCL score of 231,226 and Vulkan score of 227,554 indicate strong compute performance that benefits the game's physics and weather simulation. The pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s provide the fill-rate headroom needed for the dense cockpit displays and terrain detail in Microsoft Flight Simulator.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce 174 FPS average, Medium settings reach 155 FPS, High settings achieve 117.8 FPS, and Ultra settings yield 112.6 FPS. The gap between Low and Medium is 19 FPS, while the gap between Medium and High is 37.2 FPS, indicating a significant quality-per-frame tradeoff at this resolution. The High-to-Ultra gap is a more modest 5.2 FPS, suggesting diminishing returns beyond High settings at 1080p.

At 2560x1440, frame rates remain strong but show the GPU beginning to feel the load. Low settings average 161.1 FPS, Medium settings average 126.9 FPS, High settings average 94.3 FPS, and Ultra settings average 91.4 FPS. The Low-to-Medium gap narrows to 34.2 FPS, while the Medium-to-High gap widens to 32.6 FPS. The High-to-Ultra gap narrows further to just 2.9 FPS, reinforcing that Ultra provides marginal visual gains over High at this resolution.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings average 114.7 FPS, Medium settings average 91.9 FPS, High settings average 71.9 FPS, and Ultra settings average 64.9 FPS. The Low-to-Medium gap is 22.8 FPS, the Medium-to-High gap is 20 FPS, and the High-to-Ultra gap is 7 FPS. All 4K results remain above 60 FPS, which is notable for a simulator that often struggles at this resolution, though Ultra at 64.9 FPS leaves little headroom for demanding scenarios with dense scenery.

CPU Role

The AMD Ryzen 7 5800X3D provides 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.40 GHz and boost clock of 4.50 GHz. Its defining feature is the 96 MB of shared L3 cache, which is unusually large for a consumer desktop processor. This cache configuration is particularly beneficial for simulations that exhibit high cache locality, as it reduces the frequency of memory accesses to the slower DDR4 memory subsystem.

The CPU's benchmark profile shows strong multithreaded performance: a Cinebench R23 multicore score of 24,063, a 3DMark 16-thread score of 7,299, and a PassMark multithread score of 28,309. Single-threaded performance is also respectable, with a Cinebench R23 single-core score of 3,397 and a 3DMark single-thread score of 884. The Geekbench multicore score of 11,061 and single-core score of 2,116 align with expectations for a 5000-series processor.

The CPU's role in this game is evident from the 1080p results, where frame rates exceed 170 FPS at Low settings. At 1080p, the GPU is less stressed, allowing the CPU to become the primary determinant of frame rates. The 5800X3D's large cache helps maintain high minimum frame rates in complex scenarios, such as flying over dense urban areas or during weather updates, though the measured data provides only average FPS without min/max values.

The memory bandwidth of 51.2 GB/s from dual-channel DDR4 is a potential limitation, but the large L3 cache mitigates this by reducing memory traffic. The CPU's 105 W TDP and PCIe Gen 4 support with 20 lanes provide adequate connectivity for the RTX 5070 Ti's PCIe 5.0 x16 interface, though the system runs at Gen 4 speeds due to the CPU's capabilities. This does not appear to create a bottleneck, as the 1440p and 4K results show consistent GPU scaling.
