The overall combo rank of 378 indicates that for this game, the pairing is well-balanced, but the CPU is the star performer, pulling the system into the top quintile.

GPU Role

The AMD Radeon RX 7900 XT has a critical role to play in this simulator, primarily due to its massive 20 GB of GDDR6 memory on a 320-bit bus, yielding 800.0 GB/s of bandwidth. This is essential for Microsoft Flight Simulator, which streams enormous amounts of terrain and texture data. The GPU’s boost clock of 2394 MHz and game clock of 2025 MHz provide the raw throughput needed to process this data, while its 84 RT cores handle any ray-traced effects. The card’s 51.48 TFLOPS of FP32 performance is substantial, but the benchmark data shows that its performance is heavily influenced by the memory subsystem, as evidenced by the FPS scaling with resolution.

In this game, the GPU is the primary limiter at 4K Ultra, where average FPS drops to 56.5. The card’s 20 GB frame buffer prevents any memory-related stutters, but the compute load at 3840x2160 with Ultra settings is significant. The data shows that the GPU’s position in the 82nd percentile of all GPUs is a fair representation of its performance here; it is not a top-five card, but it is more than capable of delivering high refresh rates at 1440p. At 1080p Low, the combo hits 178.3 FPS, indicating that the GPU is not the bottleneck, and the CPU’s strong single-core performance is taking over. The GPU’s 300 W TDP and dual-slot cooler design are the practical trade-offs for this performance, but the benchmark results are what matter most for this analysis.

FAQ

A: The combo ranks 378 out of 1795, placing it in the top 21% of tested configurations. While it is not in the top 50, it is a very strong performer, and the CPU is the reason for its high placement, given its 97th percentile ranking.

Q: What is the most demanding setting tested for this combo?

A: The most demanding tested configuration is 3840x2160 with Ultra settings, producing an average FPS of 56.5. This is the only tested row that dips below the 60 FPS threshold, indicating a 4K Ultra target is not ideal for this hardware.

Measured FPS Breakdown

The measured FPS data provides a detailed picture of how this combo scales across resolutions and settings. At 1920x1080, the combo is exceptionally strong, with Low settings producing 178.3 FPS, Medium at 138.1 FPS, High at 103.9 FPS, and Ultra at 98.5 FPS. This shows that even at the highest settings, the system is well above the 60 FPS mark, and at lower settings, it approaches the refresh rate limits of many high-end monitors.

Moving to 2560x1440, the performance remains robust. Low settings average 139.2 FPS, Medium drops to 110.6 FPS, High settles at 80.8 FPS, and Ultra is nearly identical at 79.7 FPS. The data reveals a surprising trend: the difference between High and Ultra at 1440p is only 1.1 FPS, indicating that the Ultra preset does not add a significant load at this resolution. This is likely due to the CPU’s ability to keep up with the GPU’s output.

At 3840x2160, the GPU starts to feel the pressure. Low settings still deliver a playable 102.5 FPS, but Medium drops to 81.7 FPS, High to 60.6 FPS, and Ultra falls below the 60 FPS threshold to 56.5 FPS. This scaling suggests that the GPU’s compute resources are the limiting factor at 4K, as the CPU is able to feed it data faster than it can process at these higher resolutions. The 20 GB of VRAM prevents a catastrophic drop, but the raw shading power is insufficient for Ultra settings at this resolution.

Resolution Scaling

The FPS scaling from 1080p to 4K tells a clear story about the limiting component. At Low settings, the FPS drops from 178.3 at 1080p to 139.2 at 1440p (a 22% decrease), and then to 102.5 at 4K (a further 26% decrease). This is a classic GPU-bound scaling pattern, where the CPU has enough headroom to drive the GPU at lower resolutions, but the GPU’s workload increases with pixel count.

However, the scaling at Ultra settings is more revealing. The FPS drops from 98.5 at 1080p to 79.7 at 1440p (a 19% decrease), and then to 56.5 at 4K (a 29% decrease). The fact that the drop from 1080p to 1440p is smaller than the drop from 1440p to 4K indicates that the GPU is not fully saturated until it reaches 4K. At 1080p Ultra, the CPU is likely the primary limiter, as the GPU is not working at full capacity. At 4K, the GPU becomes the clear bottleneck, as the pixel shading load overwhelms the card’s 51.48 TFLOPS of FP32 performance.

This data suggests that the ideal resolution for this combo is 1440p, where the balance between CPU and GPU load is optimal. At 1080p, the CPU is limiting the frame rate, leaving GPU performance on the table. At 4K, the GPU is limiting, and the CPU’s strong single-core performance cannot compensate for the GPU’s workload. The 1440p resolution provides a balanced load, allowing both components to work in tandem.

Settings Recommendations

Based on the measured FPS rows, the best experience for this combo is at 2560x1440 with High settings, yielding an average of 80.8 FPS. This is a smooth, playable frame rate for a flight simulator, and the High preset provides a good balance of visual fidelity and performance. The Ultra preset at this resolution only costs 1.1 FPS (79.7 FPS), so it is also a viable choice if visual detail is the priority.

For users with a 1080p monitor, the Ultra preset at 98.5 FPS is the best choice, as it provides the highest visual quality without sacrificing smoothness. The data shows that even at Ultra, the combo has 38.5 FPS of headroom above the 60 FPS target, making it a very capable 1080p machine. If you prioritize maximum frame rate, the Low preset at 178.3 FPS is available, but it is unnecessary given the performance headroom.

For 4K users, the data advises caution. While Low settings at 102.5 FPS and Medium at 81.7 FPS are both playable, High settings at 60.6 FPS are borderline, and Ultra at 56.5 FPS is not ideal for a smooth experience. The best 4K experience is Medium settings, which provides a solid 81.7 FPS with a reasonable visual quality compromise. Pushing to High or Ultra will result in a noticeable drop in smoothness, which is critical in a simulator where precision matters. The data strongly suggests that 1440p is the sweet spot for this hardware, offering the best combination of visual quality and frame rate stability.

In summary, for this specific combo, the recommended settings are 2560x1440 Ultra for the best visual experience, or 2560x1440 High for a slight performance buffer. For 1080p users, 1920x1080 Ultra is the clear winner. For 4K, 3840x2160 Medium is the only setting that delivers a consistently smooth experience, as higher presets fall below the 60 FPS threshold.
