Microsoft Flight Simulator

# CPU Role

The AMD Ryzen 9 7900X brings a 12-core, 24-thread configuration based on the Zen 4 architecture, built on a 5 nm process at TSMC. Its base clock of 4.70 GHz and boost clock of 5.60 GHz place it among the higher-frequency desktop parts in the 7000 series. The processor operates on the AMD Socket AM5 platform, supports DDR5 memory in a dual-channel configuration, and provides 64 MB of shared L3 cache alongside 1 MB L2 and 64 KB L1 per core.

In Microsoft Flight Simulator, CPU performance often dictates the frame rate floor because the simulation engine handles extensive world streaming, aircraft systems, and physics calculations. The benchmark results show that at 1080p Low settings, the system reaches 204.1 FPS, which is the highest measured frame rate in the entire dataset. This suggests that the Ryzen 9 7900X provides ample single-thread and multi-thread headroom to avoid becoming the primary limiter at lower graphical loads. The processor's single-thread score of 4,238 in Passmark and 2,590 in Cinebench R20 single-core indicates strong per-core throughput, which is critical for a simulator that cannot fully parallelize all of its tasks.

The multi-threaded capabilities are equally robust. The CPU achieves a Cinebench R23 multi-core score of 43,695 and an average benchmark score of 50,556 across all tests, placing it in the 93rd percentile of all CPUs. When compared to its nearest rivals, the Ryzen 9 7900X sits within a narrow band: it trails the Intel Core Ultra 5 235 by 0.1%, the AMD Ryzen 9 5900XT by 0.4%, the Intel Core i7-13850HX by 0.5%, and the Intel Core i9-13980HX by 0.8%. These minuscule deltas highlight that the 7900X is competitive with top-tier desktop and high-end mobile processors in raw compute, though the differences are unlikely to manifest as meaningful FPS gaps in a flight simulator.

For Microsoft Flight Simulator specifically, the combination of high boost clocks and 24 threads allows the CPU to manage background tasks such as terrain loading and AI traffic while maintaining responsive frame pacing. The data shows that even at 4K Ultra, the system holds 63.6 FPS, indicating that the CPU can keep up with the GPU's workload at the most demanding settings.

# GPU Role

The NVIDIA GeForce RTX 5070 Ti is built on the Blackwell 2.0 architecture with the GB203 chip, also fabricated on a 5 nm process at TSMC. It packs 8,960 shading units, 280 TMUs, and 96 ROPs, alongside 70 RT cores and 280 tensor cores. The memory subsystem consists of 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The GPU's boost clock runs at 2452 MHz, with a base clock of 2295 MHz, and it supports PCIe 5.0 x16 connectivity.

In the context of Microsoft Flight Simulator, the GPU's role becomes more pronounced as resolution and settings increase. The 16 GB of VRAM is particularly relevant because the simulator renders vast landscapes, detailed aircraft models, and complex lighting effects that can consume significant memory capacity. At 4K Ultra, the system maintains 63.6 FPS, which demonstrates that the RTX 5070 Ti can handle the most intensive visual configuration in this test. The GPU's average benchmark score of 52,086 places it in the 87th percentile of all GPUs, and its nearest rival is the NVIDIA GeForce RTX 4080 with a delta of 0%, meaning the two cards perform virtually identically on average. The AMD Radeon RX 7700S trails by 0.8%, while the NVIDIA RTX A1000 is ahead by 2.5% and the AMD Radeon Pro W6600M is ahead by 2.5%—though these latter two are workstation-oriented parts with different driver optimizations.

The GPU's strong showing in synthetic benchmarks, such as a Passmark G3D score of 32,974 and a 3DMark Steel Nomad DX12 score of 6,604, aligns with its in-game performance. However, the flight simulator's frame rates do not scale linearly with GPU compute power because the engine's rendering pipeline includes CPU-bound sections. The measured FPS at 1080p Low (204.1 FPS) versus 1080p Ultra (109.3 FPS) shows a 94.8 FPS drop, which is attributable to increased GPU workload from higher settings, but the CPU still manages to feed frames at these rates.

# Resolution Scaling

The measured frame rates across resolutions reveal a clear pattern of GPU scaling. At 1080p, the system delivers 204.1 FPS on Low, 158.7 FPS on Medium, 119.1 FPS on High, and 109.3 FPS on Ultra. Moving to 1440p, these numbers drop to 162.4 FPS, 123.9 FPS, 96.7 FPS, and 92.5 FPS, respectively. At 4K, the values fall further to 117.3 FPS, 93.5 FPS, 71.4 FPS, and 63.6 FPS.

The percentage drops from 1080p to 4K are substantial. For Low settings, the FPS drops from 204.1 to 117.3, a reduction of roughly 42.5%. For Medium, the drop is from 158.7 to 93.5, about 41.1%. High settings go from 119.1 to 71.4, a 40.0% decline. Ultra settings see the smallest relative drop: from 109.3 to 63.6, which is approximately 41.8%. These consistent reductions across all settings indicate that the GPU is the limiting component at higher resolutions, as the CPU's performance headroom becomes less relevant when pixel count increases.

Interestingly, the scaling from 1080p to 1440p shows a smaller relative penalty than from 1440p to 4K. For instance, High settings drop from 119.1 FPS at 1080p to 96.7 FPS at 1440p, a 18.8% decrease, while the move from 1440p to 4K (96.7 to 71.4 FPS) represents a 26.2% decrease. This suggests that the RTX 5070 Ti remains capable at 1440p but begins to feel the strain at 4K, particularly with higher quality presets. The 16 GB VRAM capacity is sufficient even at 4K Ultra, as the FPS remains playable at 63.6, but the bandwidth of 896.0 GB/s and the GPU's compute throughput are the constraining factors.

The data indicates that at 1080p, the CPU likely plays a more significant role, as the FPS differences between presets are larger than at 4K. For example, the gap between 1080p Low and Ultra is 94.8 FPS, whereas at 4K the gap is 53.7 FPS. This compression at higher resolutions confirms that the GPU becomes the bottleneck as resolution increases.

# How This Combo Ranks

The combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5070 Ti ranks 133rd out of 1,795 tested combos in Microsoft Flight Simulator, placing it in the top 7.4% of all configurations. This ranking reflects the balanced nature of the pairing: the CPU's 93rd percentile standing and the GPU's 87th percentile standing combine to yield a system that is well above average for this title, but not at the absolute top tier.

Compared to other high-end combos, this setup's rank is influenced primarily by the GPU, which is slightly behind the very fastest cards. The RTX 5070 Ti's near-identical average score to the RTX 4080 suggests that combos with either card would perform similarly, but the 7900X's slight deficit against rival CPUs like the Intel Core Ultra 5 235 (0.1% slower) and the AMD Ryzen 9 5900XT (0.4% slower) may contribute to small differences in frame times. However, given that the CPU is not the limiting factor at 4K, the rank is more likely determined by the GPU's ability to sustain high FPS under heavy load.

The 133rd rank out of 1,795 means that only 132 combos achieve higher average FPS in this game. This places the system firmly in enthusiast territory, capable of running the simulator at high settings across all resolutions. The measured FPS data supports this: even at 4K Ultra, the system stays above 60 FPS, which is a key threshold for smooth gameplay in a flight simulator where camera panning and terrain streaming demand consistent frame delivery.

# Settings Recommendations

The measured rows provide clear guidance on which preset offers the best balance between visual fidelity and performance. At 4K, the Ultra preset delivers 63.6 FPS, which is playable but leaves little headroom for demanding scenes such as dense urban areas or heavy weather. High settings at 4K improve this to 71.4 FPS, while Medium reaches 93.5 FPS and Low hits 117.3 FPS.

For users prioritizing smoothness at 4K, the High preset appears optimal: it provides a 12.3% FPS increase over Ultra (71.4 vs. 63.6 FPS) while retaining most visual quality. The jump from High to Medium yields a further 30.9% improvement (93.5 FPS), but the visual difference between High and Medium in a flight simulator can be noticeable in terms of shadow quality and texture detail.

At 1440p, the High preset achieves 96.7 FPS, which is excellent for a simulator. Ultra at 1440p runs at 92.5 FPS, a modest 4.3% drop from High, making Ultra a viable choice for those with 1440p displays who want maximum fidelity. The Medium preset at 1440p (123.9 FPS) and Low (162.4 FPS) are overkill for most monitors, as they exceed typical refresh rates.

For 1080p, the system is so powerful that even Ultra runs at 109.3 FPS, which is above the 60 FPS threshold and suitable for high-refresh displays. The High preset at 119.1 FPS and Medium at 158.7 FPS offer additional headroom, but the marginal gains may not justify the visual downgrade. Given that the CPU and GPU are both strong, the recommended approach is to use the highest preset that maintains at least 60 FPS at the chosen resolution. For 4K, that is Ultra at 63.6 FPS, but High provides a safer buffer. For 1440p, Ultra is fully playable, and for 1080p, Ultra is the best choice. The data suggests that this combo is best utilized at 1440p with Ultra settings, as it delivers 92.5 FPS with no compromise on visual quality.
