# Microsoft Flight Simulator — AMD Ryzen AI Max+ 395 + NVIDIA GeForce RTX 5080

This combination of the AMD Ryzen AI Max+ 395 processor and NVIDIA GeForce RTX 5080 graphics card produces a distinctive performance profile in Microsoft Flight Simulator, one that shifts character dramatically across resolutions and settings. The measured data reveals a system that is consistently capable but whose bottleneck moves from the GPU at 4K to the CPU at 1080p, with the 16-core Zen 5 mobile processor proving to be the more variable partner in this pairing.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, which is typical for a flight simulator with heavy terrain and weather rendering. At Low settings, the average frame rate falls from 162 FPS at 1920x1080 to 131 FPS at 2560x1440, a reduction of 31 FPS, and then to 96 FPS at 3840x2160, another 35 FPS drop. The scaling from 1080p to 1440p represents a 19% decrease, while the jump from 1440p to 4K is a 27% decrease, showing that the resolution penalty accelerates as pixel count grows.

The Medium preset demonstrates similar scaling behavior. The average FPS at 1080p is 126, dropping to 102 at 1440p and then to 75 at 4K. This represents a 19% drop from 1080p to 1440p and a 26% drop from 1440p to 4K, nearly identical percentages to the Low preset. The consistency of these scaling ratios across presets suggests that the game's rendering workload scales predictably with pixel count, regardless of visual complexity settings.

High settings follow the same pattern, with averages of 95 FPS at 1080p, 76 FPS at 1440p, and 56 FPS at 4K. The percentage drops are 20% and 26% respectively. Ultra settings show 90 FPS at 1080p, 73 FPS at 1440p, and 54 FPS at 4K, with drops of 19% and 26%. The uniformity of these scaling percentages across all four presets — ranging narrowly from 19% to 20% for the first step and 26% to 27% for the second — indicates that resolution scaling is largely independent of the visual preset applied. This points to a rendering pipeline where pixel fill rate is the dominant factor as resolution increases, rather than shader complexity or texture detail.

The 4K results are particularly telling. At Ultra settings, the average FPS is 54, which is below the 56 FPS achieved at High settings at the same resolution. The difference between High and Ultra at 4K is only 2 FPS, while at 1080p the gap is 5 FPS, and at 1440p it is 3 FPS. This narrowing gap at higher resolutions suggests that the GPU is becoming the limiting factor at 4K, where the additional visual features in Ultra settings cannot be fully expressed because the rendering pipeline is already saturated. The data indicates that at 4K, the RTX 5080 is the primary constraint, while at lower resolutions, the CPU's ability to feed the GPU becomes more relevant.

GPU Role

The NVIDIA GeForce RTX 5080 brings substantial specifications to this pairing, including 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s of bandwidth. The GPU's boost clock is 2617 MHz, and it contains 10752 shading units, 336 texture mapping units, and 112 render output units. The RTX 5080 also features 84 RT cores and 336 tensor cores, which are relevant for a simulator that increasingly uses ray-traced shadows and AI-accelerated features.

The GPU's benchmark standing places it in the 87th percentile among all GPUs, with an average benchmark score of 56083. Its nearest rival is the AMD Radeon 8060S, which scores 55757, a delta of 0.6%. This is a remarkably close margin — the integrated graphics in the same CPU package nearly match the discrete RTX 5080 in aggregate benchmark terms. The Radeon RX 6750 GRE 12 GB is also close at 55698, just 0.7% behind, while the Radeon Pro W5700X trails by 2.3%. The only rival ahead is the AMD Radeon RX 9070 GRE at 57367, which leads by 2.2%.

In Microsoft Flight Simulator specifically, the GPU's 16 GB VRAM capacity is likely a factor at 4K Ultra settings, where the game's high-resolution textures and detailed terrain data can consume significant memory. The measured 4K Ultra average of 54 FPS, while playable, shows that the GPU is working near its limit. The memory bandwidth of 960.0 GB/s is substantial, and with GDDR7 memory running at 1875 MHz (30 Gbps effective), the card has ample bandwidth for texture streaming in a game that constantly loads new terrain as the aircraft moves.

The RTX 5080's pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are the specifications that most directly impact this game's fill-rate-heavy workload. Microsoft Flight Simulator renders vast landscapes, and the data shows that at 4K, the GPU's fill rate becomes the bottleneck. The 56.28 TFLOPS of FP32 compute power is more than sufficient for the game's shader work, but the resolution scaling data suggests that pixel throughput is the constraint at 4K, not compute.

The GPU's 87th percentile ranking among all GPUs, combined with its close benchmark rivalry with the integrated Radeon 8060S, is noteworthy. In this specific game, the RTX 5080's discrete advantage is clear at 4K, where the measured FPS stays above 54 at all settings, but at 1080p the GPU is often underutilized, with the CPU becoming the limiting factor.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Strix Halo. It operates at a base clock of 3.00 GHz and can boost to 5.10 GHz, with a TDP of 55 W. The processor features 64 MB of shared L3 cache, 1 MB of L2 cache per core, and 80 KB of L1 cache per core. It supports LPDDR5X memory on a quad-channel bus with 256.0 GB/s of bandwidth, and is built on TSMC's 4 nm process with a die size of 2x 70.6 mm².

The CPU's benchmark performance places it in the 95th percentile among all CPUs, with an average benchmark score of 77740. Its nearest rival is the Intel Core i9-14900K, which scores 79097, a delta of -1.7%, meaning the Ryzen AI Max+ 395 trails by that margin. The AMD Ryzen Threadripper PRO 9945WX scores 76513, which is 1.6% behind, and the AMD EPYC Embedded 8224P scores 76492, also 1.6% behind. The AMD Ryzen 9 8945HX scores 76212, 2% behind. This places the processor in a tight cluster where the top rivals are within 2% of each other, with the Intel chip holding a slight edge.

In Microsoft Flight Simulator, the CPU's role is most evident at 1080p, where the frame rates are higher and the GPU is less likely to be the constraint. At 1080p Low, the average FPS is 162, which is the highest measured value in the entire dataset. This indicates that the CPU can drive high frame rates when the GPU is not heavily loaded. However, the gap between 1080p and 1440p at Low settings is 31 FPS, suggesting that even at Low settings, the GPU begins to limit performance as resolution increases.

The CPU's 16 cores and 32 threads are relevant for a flight simulator that must simulate physics, weather, and AI traffic simultaneously. The Zen 5 architecture's single-thread performance, evidenced by a Geekbench single-core score of 2464 and a Cinebench R23 single-core score of 2044, is important because flight simulators often have a primary simulation thread that cannot be fully parallelized. The boost clock of 5.10 GHz is high for a mobile processor, and this likely contributes to the strong 1080p performance.

The CPU's memory bandwidth of 256.0 GB/s, delivered through quad-channel LPDDR5X, is another factor. Microsoft Flight Simulator streams terrain and scenery data continuously, and the CPU must feed this data to the GPU. The 64 MB of L3 cache helps reduce memory latency for frequently accessed data, which is beneficial for the game's world-streaming architecture.

The 95th percentile CPU ranking, combined with the 87th percentile GPU ranking, suggests that the CPU is the stronger component in this pairing. The benchmark data supports this: the CPU's closest rival, the i9-14900K, is a desktop part with a much higher TDP, yet the mobile Ryzen AI Max+ 395 is within 1.7% of it in aggregate benchmark score. In this game, the CPU's strength is evident at 1080p, where frame rates exceed 160 FPS at Low settings, but the GPU becomes the limiting factor at 4K, where the frame rates cluster in the 54-96 FPS range across all settings.

How This Combo Ranks

The combination of the AMD Ryzen AI Max+ 395 and the NVIDIA GeForce RTX 5080 ranks 738th out of 2996 tested combinations in Microsoft Flight Simulator. This places it in the top 25% of all tested combos, which is a strong showing for a mobile CPU paired with a desktop-class GPU.

The ranking is notable because the CPU is a mobile part with a 55 W TDP, yet it competes with desktop processors in this game. The 738th rank out of 2996 combos means that approximately 2258 other combinations performed worse, while 737 performed better. Given that the CPU's nearest rivals include the Intel Core i9-14900K and the AMD Ryzen Threadripper PRO 9945WX, both of which are high-end desktop parts, the mobile CPU's ability to hold its own is significant.

The GPU's contribution to this ranking is also important. The RTX 5080's 87th percentile standing among all GPUs, combined with the CPU's 95th percentile standing, creates a pairing where both components are above average. However, the GPU's close benchmark rivalry with the integrated Radeon 8060S — just 0.6% apart — suggests that the discrete GPU's advantage is not overwhelming in synthetic benchmarks. In this game, though, the RTX 5080's 16 GB of GDDR7 memory and dedicated bandwidth clearly provide benefits at 4K, where the integrated GPU in the CPU would likely struggle.

The rank of 738 out of 2996 also reflects the game's specific demands. Microsoft Flight Simulator is known for being CPU-intensive at lower resolutions and GPU-intensive at higher resolutions, and this combo's performance profile aligns with that. The data shows that the combo is more competitive at 1080p, where the CPU's strength is leveraged, and less competitive at 4K, where the GPU's relative weakness compared to top-tier desktop GPUs becomes apparent.

Settings Recommendations

The measured data provides clear guidance for optimizing settings in Microsoft Flight Simulator with this hardware combination. At 1920x1080, all presets deliver playable frame rates, but the differences are meaningful. Low settings produce 162 FPS, Medium produces 126 FPS, High produces 95 FPS, and Ultra produces 90 FPS. The jump from Low to Medium costs 36 FPS, while the jump from Medium to High costs 31 FPS, and the jump from High to Ultra costs only 5 FPS. This suggests that at 1080p, the High-to-Ultra transition is the most efficient in terms of visual quality per frame rate cost, while the Low-to-Medium transition is the most expensive.

At 2560x1440, the pattern shifts. Low produces 131 FPS, Medium produces 102 FPS, High produces 76 FPS, and Ultra produces 73 FPS. The gap between High and Ultra narrows to just 3 FPS, making Ultra the recommended choice for users who want maximum visual quality at this resolution without significant frame rate penalty. The Medium preset, at 102 FPS, offers a smooth experience with a 26 FPS cost over Low, which is reasonable.

At 3840x2160, the frame rates are lower across the board. Low produces 96 FPS, Medium produces 75 FPS, High produces 56 FPS, and Ultra produces 54 FPS. The Medium preset at 75 FPS is the sweet spot for 4K gaming, as it maintains a frame rate above 60 FPS while providing better visual quality than Low. The High and Ultra presets both fall below 60 FPS, with averages of 56 and 54 respectively, which may be acceptable for a flight simulator but is not ideal for smooth gameplay.

The Medium preset at 4K also has the only complete min/max data in the dataset, with a minimum of 64 FPS and a maximum of 86 FPS. This indicates that the Medium preset at 4K is not only the best average performer above 60 FPS, but it also maintains a minimum frame rate above 60 FPS, which is crucial for a simulator where smooth panning across terrain is essential. The recommendation is clear: for the best balance of visual quality and performance, use Medium settings at 4K, High settings at 1440p, and Ultra settings at 1080p.
