Microsoft Flight Simulator

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 5050 delivers a playable yet resolution-sensitive experience in Microsoft Flight Simulator. The data shows a system that scales predictably with settings, but the GPU becomes the primary constraint as resolution climbs, while the CPU provides a stable foundation. The combo ranks 1814th out of 2996 tested configurations in this title, placing it in the lower-middle portion of the database, indicating that while capable, it is not optimized for the highest-end flight simulation workloads.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, with the most significant drop occurring between 1080p and 4K. At Low settings, the average frame rate falls from 106 FPS at 1920x1080 to 85 FPS at 2560x1440, a reduction of approximately 20%, and then further to 63 FPS at 3840x2160, representing a 41% total decrease from the 1080p baseline. This steep decline at 4K indicates that the rendering pipeline becomes heavily pixel-bound, with the RTX 5050's 8 GB of GDDR6 memory and 128-bit bus width struggling to maintain throughput at higher resolutions.

At High settings, the scaling curve is even more pronounced. The average FPS drops from 62 at 1080p to 50 at 1440p, a 19% loss, and then plummets to 37 at 4K, a 40% reduction from the 1080p figure. This suggests that the GPU's fill rate and memory bandwidth are the limiting factors, as the flight simulator's detailed terrain and aircraft models demand more from the rasterization pipeline at higher resolutions. The Ultra preset shows a similar trajectory, with averages of 59, 48, and 35 FPS across 1080p, 1440p, and 4K respectively, confirming that the GPU is the bottleneck regardless of quality setting.

The Medium preset, which is the only one with min/max FPS data, shows a 1080p average of 82 FPS with a minimum of 70 and maximum of 95. At 1440p, the average drops to 66 FPS with a range of 57 to 76, and at 4K it falls to 49 FPS with a range of 42 to 56. The min FPS values are particularly telling: at 4K, the system can dip to 42 FPS, which approaches the lower boundary of smooth gameplay for a flight simulator where consistent frame pacing matters for immersion. The scaling from 1080p to 4K at Medium settings shows a 40% performance penalty, mirroring the other presets and reinforcing that resolution, not settings complexity, is the dominant variable.

The data suggests that the i5-13400F with 10 cores and 16 threads has sufficient headroom to feed the GPU at all resolutions, as the FPS drops are consistent with pixel-count increases rather than CPU stalls. However, the absolute numbers at 4K — 37 FPS on High and 35 FPS on Ultra — fall below the 60 FPS target that many users consider the minimum for a smooth experience. The 1440p results are more balanced, with High and Ultra averaging 50 and 48 FPS respectively, indicating that this is the practical ceiling for high-quality settings with this combination.

FAQ

How This Combo Ranks

The combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 5050 achieves a rank of 1814 out of 2996 tested combos in Microsoft Flight Simulator. This positions the system in the lower-middle tier of the database, with 1182 combos ranking below it and 1813 ranking above. The percentile placement indicates that while this is not a top-tier configuration, it is far from the bottom, and the measured FPS data shows it is capable of running the game at playable framerates on most presets.

The ranking is influenced by both components. The CPU alone holds a percentile of 77 against all processors, with an average benchmark score of 25292, placing it in the upper quartile. Its nearest rivals include the AMD Ryzen 9 6900HS with a nearly identical score of 25284 and a deltaPct of 0, the Intel Core 5 120 at 25362 with a -0.3% delta, and the AMD Ryzen 5 5600X3D at 25365 with a -0.3% delta. This means the i5-13400F is essentially on par with these alternatives in synthetic benchmarks, with no meaningful performance gap.

The GPU, however, holds a lower percentile of 66 against all GPUs, with an average benchmark score of 21035. Its nearest rivals include the AMD Radeon RX Vega M GL at 21153 (-0.6% delta), the AMD Radeon HD 8970M at 21237 (-1% delta), the AMD Radeon RX 5600 XT at 20713 (1.6% delta), and the NVIDIA RTX A4000 Mobile at 21379 (-1.6% delta). The GPU's 66th percentile is notably lower than the CPU's 77th, suggesting that the graphics card is the weaker link in this pairing, which aligns with the resolution scaling analysis showing GPU-bound behavior at higher resolutions.

The disparity between the CPU and GPU percentiles explains the overall rank. In a game like Microsoft Flight Simulator, which is known for demanding both CPU and GPU resources, the combo's rank of 1814 reflects the GPU's inability to fully leverage the CPU's capabilities. The data shows that the CPU could likely push higher frame rates if paired with a stronger GPU, but with the RTX 5050, the system is capped by the graphics card's 8 GB memory and 13.17 TFLOPS of FP32 performance.

Measured FPS Breakdown

At 1920x1080, the system delivers an average of 106 FPS on Low settings, which drops to 82 FPS on Medium with a minimum of 70 and maximum of 95. High settings produce 62 FPS average, while Ultra yields 59 FPS. The spread from Low to Ultra is 47 FPS, showing that the GPU has significant headroom at this resolution and that settings have a major impact on performance.

At 2560x1440, the Low preset averages 85 FPS, a 20% reduction from 1080p. Medium settings average 66 FPS with a minimum of 57 and maximum of 76. High settings drop to 50 FPS, and Ultra falls to 48 FPS. The gap between Low and Ultra narrows to 37 FPS at this resolution, indicating that the GPU is starting to become more constrained as pixel count increases.

At 3840x2160, the Low preset averages 63 FPS, which is a 41% decline from the 1080p Low result. Medium settings average 49 FPS with a minimum of 42 and maximum of 56. High settings produce 37 FPS, and Ultra yields 35 FPS. The difference between Low and Ultra at 4K is 28 FPS, showing that the GPU is the dominant bottleneck and settings adjustments have less impact on overall performance compared to lower resolutions.

The Medium preset is the only one with complete min/max data across all resolutions. At 1080p, the range is 70 to 95 FPS; at 1440p, it is 57 to 76 FPS; and at 4K, it is 42 to 56 FPS. The minimum FPS values follow the same scaling pattern as averages, with the 4K minimum of 42 FPS being the lowest recorded in the dataset. This consistency suggests that the system does not exhibit sudden frame spikes or stutters, but rather a steady degradation as resolution increases.

GPU Role

The NVIDIA GeForce RTX 5050 is built on the Blackwell 2.0 architecture with a 5 nm process node and 16,900 million transistors on a 149 mm² die. It operates at a base clock of 2317 MHz and a boost clock of 2572 MHz, with memory running at 2500 MHz (20 Gbps effective). The GPU has 8 GB of GDDR6 memory on a 128-bit bus, providing 320.0 GB/s of bandwidth. These specifications directly influence the measured FPS results in Microsoft Flight Simulator.

The 8 GB memory capacity is a critical factor at 4K resolution. Flight Simulator's high-resolution textures for terrain, aircraft, and scenery can exceed 8 GB of VRAM usage, which would force the GPU to spill over into system memory, causing significant performance penalties. The measured data supports this: at 4K, the average FPS across all presets ranges from 35 to 63, with the higher settings (High and Ultra) falling below 40 FPS. The 128-bit memory bus and 320.0 GB/s bandwidth also limit the speed at which texture data can be transferred, which is why the scaling from 1080p to 4K is so steep.

The GPU's compute capabilities include 2560 shading units, 80 TMUs, and 32 ROPs, with 20 RT cores and 80 tensor cores. Its FP32 performance is rated at 13.17 TFLOPS, which is modest for a modern GPU. In the context of Flight Simulator, which relies heavily on draw calls for complex scenery and physics calculations for flight dynamics, this compute throughput is sufficient for 1080p and 1440p gaming but falls short at 4K, where the pixel fill rate of 82.30 GPixel/s becomes a limiting factor.

The GPU's benchmark scores provide additional context. Its PassMark G3D score is 17326, with a DirectX 12 score of 66 and DirectX 11 score of 150. The Geekbench OpenCL score is 90334, and the Vulkan score is 89381. The 3DMark Steel Nomad DX12 score is 2502. These scores place the GPU in the 66th percentile overall, which is below the CPU's 77th percentile, confirming that the GPU is the weaker component in this pairing. The nearest rival, the AMD Radeon RX 5600 XT, has a 1.6% higher average score, indicating that the RTX 5050 is in a competitive but not dominant position.

Settings Recommendations

For users prioritizing a consistent 60 FPS experience, the data shows that 1080p with Medium settings is the optimal choice, delivering an average of 82 FPS with a minimum of 70. This provides a comfortable margin above 60 FPS, ensuring smooth gameplay even during complex scenes. The High preset at 1080p, at 62 FPS average, is also viable but offers less headroom for frame drops.

At 1440p, the Medium preset provides 66 FPS average with a 57 FPS minimum, which is the best balance of visual quality and performance at this resolution. The High preset at 50 FPS may be acceptable for users who prefer visual fidelity over frame rate, but the minimum FPS is not measured, so there is a risk of drops below 50 FPS. The Ultra preset at 48 FPS is borderline, as it may induce noticeable stuttering in a simulator where smooth camera panning is essential.

At 4K, none of the presets achieve 60 FPS. The Low preset at 63 FPS is the only configuration above 60 FPS, but it sacrifices significant visual quality. The Medium preset at 49 FPS is the highest quality option that maintains a playable frame rate, with a minimum of 42 FPS. For users with 4K displays, the recommendation is to use Medium settings or consider reducing resolution to 1440p for a better experience.

The Ultra preset is not recommended at any resolution, as it provides only marginal visual improvements over High while incurring significant performance costs. At 1080p, the difference between High and Ultra is just 3 FPS (62 vs 59), and at 4K, it is 2 FPS (37 vs 35). This indicates that the Ultra preset's additional effects have a negligible impact on this GPU, making High the more efficient choice for the same visual experience.

CPU Role

The Intel Core i5-13400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It has a 20 MB shared L3 cache, with 80 KB L1 and 1.25 MB L2 per core. The CPU is built on the Raptor Lake architecture using a 10 nm process, and it supports DDR4 and DDR5 memory in a dual-channel configuration. These specifications provide a solid foundation for Microsoft Flight Simulator, which benefits from multi-threaded performance for AI traffic, weather simulation, and physics.

The CPU's benchmark scores indicate strong multi-threaded capability. Its Cinebench R23 multicore score is 22604, with a single-core score of 3191. The Geekbench multicore score is 11068, and the single-core score is 1996. The 3DMark scores show scaling from 1880 for 2 threads to 7314 for 16 threads, with a max-threads score of 7307. The PassMark multithread score is 25032, with a physics score of 1437. These results place the CPU in the 77th percentile, with an average benchmark score of 25292.

In Microsoft Flight Simulator, the CPU's role is to handle the game's simulation logic, which includes flight dynamics, weather systems, and terrain loading. The 10 cores and 16 threads provide ample parallelism for these tasks, and the measured FPS data suggests that the CPU does not become a bottleneck in this configuration. At 1080p Low, the system reaches 106 FPS, which is a strong result that would be difficult to achieve if the CPU were limiting performance.

The CPU's nearest rivals include the AMD Ryzen 9 6900HS with a deltaPct of 0, the Intel Core 5 120 with a -0.3% delta, and the AMD Ryzen 5 5600X3D with a -0.3% delta. These small deltas indicate that the i5-13400F performs nearly identically to these alternatives in synthetic benchmarks. However, in a game like Flight Simulator, the CPU's single-thread performance is also important, and its 3DMark single-thread score of 960 and Cinebench R23 single-core score of 3191 suggest it has sufficient per-core performance for the game's main thread.

The CPU's 65 W TDP and support for DDR4/DDR5 memory make it a versatile choice, but the data shows that its performance is not the limiting factor in this combo. The bottleneck is clearly the GPU, as evidenced by the significant FPS drops at higher resolutions that are consistent with GPU-bound behavior. If the CPU were the constraint, the FPS would remain flat across resolutions, which is not the case in the measured data.
