Microsoft Flight Simulator

The AMD Ryzen 7 7700X and AMD Radeon RX 7800 XT pairing delivers a robust, but not class-leading, experience in Microsoft Flight Simulator. With a combo rank of 655 out of 1,795 tested configurations, this system sits comfortably in the upper third of all possible builds, indicating strong performance for a high-refresh 1440p or entry-level 4K setup. The data shows a clear story of a balanced system where the CPU’s strong single-threaded architecture and the GPU’s substantial memory bandwidth define the frame rate across different settings.

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

The AMD Ryzen 7 7700X is built on the Zen 4 architecture, codenamed Raphael, and manufactured on a 5 nm process by TSMC. It features 8 cores and 16 threads, with a base clock of 4.50 GHz and a boost clock of 5.40 GHz. This configuration places it in the 89th percentile of all CPUs, with an average benchmark score of 34,313. Notably, its single-thread performance is exceptional, as evidenced by a 3DMark single-thread score of 1,090 and a Cinebench R23 single-core score of 4,281. These numbers are crucial for Microsoft Flight Simulator, a title that heavily relies on single-core processing for flight physics, weather simulation, and complex scenery loading.

In multi-threaded workloads, the 7700X also holds its own. Its Cinebench R23 multicore score of 30,325 and Geekbench multicore score of 15,538 show it can handle the game’s background tasks, such as AI traffic and terrain streaming, without becoming a bottleneck. The CPU’s 32 MB of shared L3 cache and support for DDR5 memory with a bandwidth of 83.2 GB/s further reduce latency when feeding the GPU with positional and rendering data. The 7700X’s nearest rivals in synthetic benchmarks include the Intel Core i5-13500, which is only 0.4% ahead, and the Intel Core i7-12800HX, 0.5% ahead. This indicates that the CPU is operating at a performance level that is essentially tied with these competitors, meaning any frame rate differences in the game are more likely attributed to the GPU or game engine optimization than CPU compute limits.

The CPU’s role in this combo becomes clear when considering the game’s low-settings results. At 1080p with Low settings, the system achieves 149 FPS. This high frame rate is a direct result of the CPU’s ability to process the game’s core simulation loop quickly, as the GPU is under less stress. The 7700X’s high boost clock of 5.40 GHz and a PassMark single-thread score of 4,190 ensure that the main game thread is rarely starved, allowing for the high refresh rates seen at lower resolutions.

FAQ

Q: How well does this combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average frame rate is 49.1 FPS. This is a playable level for a flight simulator, which is less sensitive to frame rate than fast-paced shooters, but it is below the 60 FPS threshold often desired for smooth camera movement.

Q: Is the CPU or GPU the main bottleneck at 1080p?

A: The data indicates the CPU is the primary limiter at 1080p. When moving from Low to Ultra settings at 1920x1080, the frame rate drops from 149 FPS to 79.6 FPS. The large drop with increased settings shows the GPU is now doing more work, but the CPU’s high single-thread performance is what allows the Low setting to hit such high numbers.

Q: What is the best resolution to play this game with this hardware?

A: Based on the measured FPS, 2560x1440 offers the best balance. At High settings, it produces 67.3 FPS, which is a good mix of visual fidelity and smoothness. At 4K, the frame rate drops below 50 FPS at High settings, making 1440p the more consistent choice.

Q: How does the 7700X compare to its closest rivals in synthetic benchmarks?

A: The 7700X is statistically tied with its nearest rivals. It is 0.4% behind the Intel Core i5-13500 and 0.5% behind the Intel Core i7-12800HX in average benchmark score. It is also 0.8% ahead of the Intel Core Ultra 7 165H and 0.8% ahead of the AMD EPYC 4244P.

Q: Does the RX 7800 XT’s 16 GB of memory help at high resolutions?

A: The 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth. This is sufficient for the game’s high-resolution textures, as the system still manages 68.6 FPS at 4K Medium settings. The memory capacity is not the limiting factor at these settings.

Q: Is the 7700X a good match for the RX 7800 XT in this game?

A: The data suggests it is a well-balanced pairing. The system achieves a rank of 655 out of 1,795 combos, putting it in the top 36% of tested configurations. Neither component appears to severely bottleneck the other, as frame rates scale predictably with resolution and settings.

How This Combo Ranks

The combo of the AMD Ryzen 7 7700X and the AMD Radeon RX 7800 XT ranks 655th out of 1,795 tested combinations in Microsoft Flight Simulator. This placement in the 36th percentile of all combos indicates a solid, above-average performance tier. It places this system ahead of a majority of builds, but it is not at the extreme top end, which would be reserved for flagship CPUs paired with top-tier GPUs.

The GPU’s percentile ranking is 76th among all GPUs, while the CPU sits at the 89th percentile. This discrepancy suggests that while the CPU is a high-end part, the GPU is a mid-to-high-end part, and the overall combo rank reflects a balance between the two. The RX 7800 XT’s average benchmark score is 32,619, placing it just 0.2% behind the AMD FirePro S9300 X2 and 0.4% ahead of the NVIDIA P104-100. This shows the GPU is performing as expected for its class. The fact that the combo rank is lower than the CPU’s individual percentile suggests that the GPU is the more restrictive component in this pairing, particularly at higher resolutions where pixel throughput is critical.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance scaling across three resolutions and four quality presets.

At 1920x1080, the system is highly capable. The Low preset delivers 149 FPS, which is excellent for competitive or high-refresh play. Medium reduces the frame rate to 113.9 FPS, a 23.6% drop. High further reduces it to 85.2 FPS, and Ultra brings it down to 79.6 FPS. The gap between High and Ultra is only 5.6 FPS, suggesting diminishing returns for the extra graphical load.

Moving to 2560x1440, the frame rates remain strong. Low yields 119.6 FPS, showing only a 19.7% drop from the 1080p Low result. Medium produces 93.4 FPS, and High drops to 67.3 FPS. Ultra is nearly identical to High at 67.5 FPS, indicating that at this resolution, the GPU is beginning to hit a performance ceiling with the most demanding settings.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings produce 86.2 FPS, which is still smooth. Medium yields 68.6 FPS, High drops to 48.9 FPS, and Ultra is nearly identical at 49.1 FPS. The fact that High and Ultra are the same at 4K suggests that the GPU is fully saturated, and the CPU is not able to push more frames due to the sheer pixel count.

Resolution Scaling

The scaling from 1080p to 4K reveals the nature of the bottleneck in this system. At Low settings, the frame rate drops from 149 FPS at 1080p to 119.6 FPS at 1440p, a 19.7% decrease, and then to 86.2 FPS at 4K, an additional 27.9% decrease from 1440p. This progressive drop with resolution indicates that the CPU is strong enough to maintain high frame rates even as pixel count increases, but the GPU’s workload is growing.

At Ultra settings, the scaling is more dramatic. The system moves from 79.6 FPS at 1080p to 67.5 FPS at 1440p, an 15.2% drop, and then to 49.1 FPS at 4K, a 27.3% drop from 1440p. The smaller drop from 1080p to 1440p at Ultra compared to Low suggests the GPU is already heavily taxed at 1080p Ultra, so the relative increase in work is smaller.

The data strongly suggests that the RX 7800 XT is the limiting component at 4K, especially at High and Ultra settings. The CPU’s high single-thread performance keeps the simulation running fluidly, but the GPU cannot render the frames fast enough to exceed 50 FPS at that resolution. Conversely, at 1080p Low, the CPU is likely the limiting factor, as the GPU can render frames faster than the CPU can issue draw calls. This is a classic sign of a balanced system at mid-range resolutions, with the CPU leading at low resolutions and the GPU taking over at high resolutions.
