Microsoft Flight Simulator

The AMD Ryzen 5 9600X and AMD Radeon RX 6600 XT combination lands at rank 1335 out of 1795 tested combos for Microsoft Flight Simulator. That places this pairing in the lower-middle tier of the database, meaning it will run the sim, but it won't be a showcase rig. The ranking reflects a system that is capable at lower settings and resolutions, but one that struggles to deliver high-refresh or maxed-out experiences at higher presets.

How This Combo Ranks

The combo's rank of 1335 out of 1795 places it in the 74th percentile, meaning roughly a quarter of tested configurations perform worse. This is not a top-tier setup, but it is far from a bottom-of-the-barrel pairing. The data shows a system that is serviceable for flight simulation, which is notoriously demanding on both the CPU and GPU due to its complex scenery rendering and physics calculations. The CPU itself, the Ryzen 5 9600X, sits in the 85th percentile against all CPUs, with an average benchmark score of 28246. Its nearest rivals are the Intel Core i5-13490F (28173, 0.3% slower), AMD Ryzen 5 230 (28164, 0.3% slower), AMD Ryzen 7 8845HS (28369, 0.4% faster), and Intel Core i5-14500T (28377, 0.5% faster). The CPU is a solid mid-pack performer. The GPU, the RX 6600 XT, holds the 71st percentile against all GPUs, with an average score of 27985. Its rivals include the NVIDIA GeForce GTX 980 Ti (27956, 0.1% slower) and the NVIDIA GeForce RTX 3070 (28238, 0.9% faster). The GPU is also a mid-tier part. The combination of two mid-tier parts results in the overall rank, indicating that neither component is a bottleneck in a way that would hold the other back severely, but both are limited in absolute performance.

GPU Role

The Radeon RX 6600 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process. It has 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s of bandwidth. The boost clock is rated at 2589 MHz, with a game clock of 2359 MHz. In terms of raw throughput, it offers 10.60 TFLOPS of FP32 performance. The 8 GB VRAM is a significant factor in Microsoft Flight Simulator, as the game loads vast amounts of texture data for terrain and aircraft. At 4K Ultra settings, the card hits its limits, and the data confirms this with an average of 35.7 FPS. The GPU's 64 ROPs and 128 TMUs contribute to its pixel and texture fill rates of 165.7 GPixel/s and 331.4 GTexel/s, respectively. The card also features 32 ray accelerators, though Flight Simulator's use of ray tracing is minimal. The GPU's benchmark scores show it is competitive with the GTX 980 Ti (27956) and R9 M395X (27883), but trails the RTX 3070 (28238) by a small margin of 0.9%. This suggests that while the card is aging, it still holds its own against older high-end parts. The 8 GB frame buffer, however, is a clear constraint at higher resolutions and settings, where the measured FPS drops disproportionately compared to lower settings.

CPU Role

The Ryzen 5 9600X is a 6-core, 12-thread processor based on the Zen 5 architecture (Granite Ridge), manufactured on a 4 nm process by TSMC. It has a base clock of 3.90 GHz and a boost clock of 5.40 GHz. The CPU has 32 MB of shared L3 cache. For simulation games like Microsoft Flight Simulator, single-thread performance is critical, and the CPU delivers strong results: its Cinebench R23 single-core score is 3603, and its 3DMark single-thread score is 1253. Multi-threaded performance is also respectable, with a Cinebench R23 multi-core score of 25525 and a Geekbench multi-core score of 15182. The CPU's benchmark data shows it is effectively tied with its nearest rivals in average score, with deltas of less than 0.5% against the i5-13490F, Ryzen 5 230, Ryzen 7 8845HS, and i5-14500T. This means that at 1080p resolution, where the CPU is more likely to be the limiting factor, the Ryzen 5 9600X should provide a smooth experience when paired with a sufficiently powerful GPU. The 65W TDP and dual-channel DDR5 memory support (89.6 GB/s bandwidth) ensure that the CPU can feed data to the GPU without significant bottlenecks. The CPU's PassMark single-thread score of 4570 is strong, indicating it can handle the complex flight model calculations and AI traffic that the sim runs on the main thread.

Measured FPS Breakdown

The measured FPS data provides a clear picture of this combo's capabilities across resolutions and settings. At 1080p, the system performs best at Low settings with an average of 101.3 FPS. Medium settings yield 75.7 FPS, High settings drop to 58.8 FPS, and Ultra settings produce 53.4 FPS. This shows that at 1080p, the system can achieve playable frame rates at all settings, though Ultra is only borderline. Moving to 1440p, the averages drop noticeably: Low settings give 81.4 FPS, Medium gives 60.5 FPS, High gives 45.5 FPS, and Ultra gives 43.2 FPS. The drop from High to Ultra at 1440p is only 2.3 FPS, which suggests the GPU is already struggling. At 4K, the results are more demanding. Low settings yield 61.1 FPS, which is playable, but Medium drops to 46.9 FPS, High to 32.1 FPS, and Ultra to 35.7 FPS. Interestingly, the difference between High and Ultra at 4K is 3.6 FPS, which is small, indicating that the GPU is overwhelmed by the resolution regardless of setting. The data indicates that the RX 6600 XT is the primary limiting factor at higher resolutions, as the FPS scales with resolution more than with settings changes.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the balance of the system. At Low settings, the FPS drops from 101.3 at 1080p to 81.4 at 1440p (a 19.7% drop) and then to 61.1 at 4K (a 24.9% drop from 1440p). This scaling is relatively mild, suggesting that at Low settings, the CPU is still a significant contributor to performance, especially at 1080p where the GPU is less taxed. However, at Ultra settings, the FPS drops from 53.4 at 1080p to 43.2 at 1440p (a 19.1% drop) and then to 35.7 at 4K (a 17.4% drop from 1440p). The smaller percentage drops at Ultra settings indicate that the GPU is heavily loaded regardless of resolution. The data shows that at 4K Ultra, the system is clearly GPU-bound, as the RX 6600 XT cannot maintain a high frame rate even with the CPU's strong single-thread performance. The 8 GB VRAM is likely a contributing factor, as higher resolutions require more memory bandwidth and capacity. The scaling pattern suggests that for 1080p gaming, the CPU and GPU are well-matched, but as resolution increases, the GPU becomes the clear bottleneck, especially at Medium and higher settings.

Settings Recommendations

Given the measured data, the best experience for this combo depends on the target resolution. For 1080p gaming, High settings at 58.8 FPS offers a good balance of visual fidelity and smoothness, but Ultra at 53.4 FPS is also viable if you prefer maximum detail. For 1440p, the data shows that Medium settings at 60.5 FPS is the sweet spot, as it provides a smooth 60 FPS experience. High settings at 45.5 FPS is playable but not ideal for a flight sim where smooth panning matters. Ultra at 43.2 FPS is not recommended. For 4K, the situation is more constrained. Low settings at 61.1 FPS is the only preset that delivers a consistently smooth experience. Medium at 46.9 FPS is borderline, but High and Ultra at 32.1 and 35.7 FPS, respectively, are below the threshold for comfortable play. The data indicates that users should prioritize resolution over settings: if you have a 4K display, stick to Low or Medium; if you have a 1080p display, you can push to High or Ultra. The system is not capable of a "max everything" experience at any resolution, but it can deliver a solid simulation experience with the right compromises.
