Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the data for the Intel Core Ultra 5 245 paired with the NVIDIA GeForce RTX 5080 reveals a fascinating balance between the CPU and GPU. The benchmark results show a combination that is highly capable across all resolutions, but the performance scaling from 1080p to 4K tells a clear story about which component is the limiting factor. This system consistently delivers smooth, playable framerates, but the way those numbers shift under different loads provides key insights into its architectural strengths.

Resolution Scaling

The measured FPS data shows a predictable and steep decline as resolution increases, which is the classic signature of a GPU-bound workload at higher pixel counts. At 1080p with High settings, the combo produces 128 FPS, but at 1440p that drops to 103 FPS, and at 4K it falls to 76 FPS. This represents a 41% reduction in framerate when moving from 1080p to 4K, a significant hit that suggests the RTX 5080 is being pushed to its limits by the sheer pixel count.

However, the scaling pattern becomes more nuanced when examining the Low and Medium presets. At Low settings, the system achieves 218 FPS at 1080p, 176 FPS at 1440p, and 130 FPS at 4K. The drop from 1080p to 4K here is 40%, which is similar to High, but the absolute numbers are much higher. The Medium preset tells a more interesting story: it shows a 170 FPS at 1080p, 137 FPS at 1440p, and 101 FPS at 4K, with the 4K result including a minimum framerate of 86 FPS and a maximum of 116 FPS.

The fact that the framerate drops consistently across all settings points to a combination where neither component is severely bottlenecking the other at any single resolution. The RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are clearly sufficient for the 4K textures, while the Core Ultra 5 245's 14 cores and 14 threads keep up with the simulation's physics and scenery calculations. The data suggests that at 4K, the GPU is the primary bottleneck, as the FPS difference between High (76 FPS) and Ultra (72 FPS) is minimal, indicating the graphics card is saturated.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this pairing sits at rank 171 out of 3714 combos in Microsoft Flight Simulator. This places it in the top 4.6% of all tested systems, a remarkable position that reflects the high-end nature of both components. The combo rank is a holistic measure that accounts for the interplay between the CPU and GPU, and this result shows a well-matched pair that excels in this specific simulation.

The percentile data for each component reinforces this ranking. The Intel Core Ultra 5 245 scores in the 90th percentile against all CPUs, while the RTX 5080 sits in the 87th percentile against all GPUs. This near-parity in relative performance is unusual and suggests that neither component is holding the other back significantly. The CPU's average benchmark score of 48995 places it within 1% of rivals like the AMD Ryzen 7 PRO 5755G (49196, -0.4% delta) and the AMD Ryzen 9 7900 (49228, -0.5% delta), while the GPU's average score of 56083 puts it just 0.6% behind the AMD Radeon 8060S (55757) and 0.7% behind the AMD Radeon RX 6750 GRE 12 GB (55698).

This ranking data indicates that the combo is not just a collection of powerful parts, but a synergistic pairing that performs above the sum of its components. The 171st rank out of 3714 is a strong indicator that this system is among the top echelon for Flight Simulator, and the benchmark results support this with consistent framerates across all tested configurations.

GPU Role

The NVIDIA GeForce RTX 5080 is the workhorse of this combo, and its specifications explain why it handles Flight Simulator's demanding visuals so well. With 10752 shading units, 336 texture mapping units, and 112 raster output pipelines, the GPU has the raw compute power to render complex scenery. The 84 ray tracing cores and 336 tensor cores further enhance its capability for advanced lighting and AI-driven upscaling, though the benchmark data does not specify whether these features were enabled.

The GPU's 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is crucial for streaming high-resolution textures in a game that loads vast geographical areas. The memory clock runs at 1875 MHz, effective 30 Gbps, and the base and boost clocks are 2295 MHz and 2617 MHz respectively. These clock speeds allow the GPU to sustain high framerates, as evidenced by the measured results.

The RTX 5080's benchmark scores further contextualize its performance. It achieves a 3DMark Steel Nomad DX12 score of 8637, a Geekbench OpenCL score of 235901, and a Vulkan score of 255450. The Passmark G3D score of 36565 and GPU compute score of 21789 indicate strong overall performance. The GPU's percentile rank of 87 versus all GPUs confirms that it is a top-tier part, and its nearest rivals in average benchmark score are all within 2.3% of its performance, showing that it competes closely with other high-end cards. The 4K Ultra result of 72 FPS demonstrates that even at maximum settings, the RTX 5080 provides a playable experience, though the 4K Low result of 130 FPS shows where headroom exists.

Measured FPS Breakdown

The complete set of measured FPS data provides a detailed picture of performance across three resolutions and four settings. At 1920x1080, the system delivers 218 FPS on Low, 170 FPS on Medium, 128 FPS on High, and 122 FPS on Ultra. The Medium preset is the only one at this resolution to report min and max framerates, showing 144 FPS minimum and 195 FPS maximum, which indicates smooth frame pacing with no severe dips.

Moving to 2560x1440, the results are 176 FPS on Low, 137 FPS on Medium, 103 FPS on High, and 98 FPS on Ultra. The Medium preset again shows a minimum of 116 FPS and a maximum of 157 FPS. At 3840x2160, the system produces 130 FPS on Low, 101 FPS on Medium, 76 FPS on High, and 72 FPS on Ultra. The 4K Medium preset reports a minimum of 86 FPS and a maximum of 116 FPS.

These numbers reveal a consistent pattern: the difference between High and Ultra settings is remarkably small at every resolution. At 1080p, the gap is only 6 FPS (128 vs 122), at 1440p it is 5 FPS (103 vs 98), and at 4K it is 4 FPS (76 vs 72). This suggests that the Ultra preset may introduce visual improvements that are not heavily taxing on the GPU, or that the CPU becomes a limiting factor at higher settings, preventing the GPU from fully utilizing its headroom. The Low to Medium jump is more substantial, with a 48 FPS increase at 1080p, a 39 FPS increase at 1440p, and a 29 FPS increase at 4K, indicating that the Medium preset is where the GPU starts to work harder.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p, the Medium preset delivers 170 FPS with a minimum of 144 FPS, which is well above the threshold for smooth gameplay. At 1440p, it achieves 137 FPS with a minimum of 116 FPS, still providing an excellent experience. At 4K, the Medium preset produces 101 FPS with an 86 FPS minimum, which is playable on high refresh rate displays.

The High preset is also a strong choice, especially for users with 4K displays, as it delivers 76 FPS at 4K and 128 FPS at 1080p. However, the marginal difference between High and Ultra makes Ultra the less attractive option. The data shows that Ultra only costs 4-6 FPS compared to High, but the visual gains may be worth it for those who prioritize image quality over framerate. For users with 120Hz or 144Hz monitors, the Medium preset at 1440p is the sweet spot, offering 137 FPS that comfortably exceeds refresh rate targets.

The Low preset is only recommended for competitive or maximum framerate scenarios, as it produces 218 FPS at 1080p and 176 FPS at 1440p. However, the visual compromise is significant, and the data suggests that the system has enough headroom to run Medium or High without sacrificing smoothness. The 4K Ultra result of 72 FPS is the only configuration that dips below 60 FPS, so users with 60Hz 4K displays can safely use Ultra, while those with higher refresh rates should prefer Medium or High.

CPU Role

The Intel Core Ultra 5 245 plays a critical role in this combo, particularly in a simulation like Flight Simulator that relies heavily on single-threaded performance for game logic and physics. The CPU features 14 cores and 14 threads, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. This high boost clock is essential for the demanding single-threaded tasks that Flight Simulator presents, and the benchmark data supports this.

The CPU's Cinebench R23 scores are particularly telling: 32924 in multicore and 4648 in single-core. These scores indicate strong multi-threaded capability for scenery loading and physics calculations, while the single-core score ensures responsive frame pacing. The Passmark single-thread score of 4394 further confirms its strength in this area. The CPU's L3 cache of 24 MB (shared) and L2 cache of 3 MB per core provide fast access to frequently used data, which is crucial for the large world data Flight Simulator streams.

The CPU's percentile rank of 90 against all CPUs places it in the top 10%, and its average benchmark score of 48995 is within 0.8% of the Intel Core i5-14600K (48618, 0.8% delta). This close competition shows that the Ultra 5 245 is a capable performer that does not bottleneck the RTX 5080 in most scenarios. The CPU's 65W TDP and 3nm process node (TSMC) indicate efficient power consumption, allowing the GPU to receive adequate power headroom. The CPU's memory bandwidth of 102.4 GB/s with dual-channel DDR5 support ensures that data can flow quickly to the GPU, minimizing stutter in a game known for its data-intensive nature.
