Microsoft Flight Simulator

# Microsoft Flight Simulator — Intel Core Ultra 5 245 + AMD Radeon RX 9070 XT

The Intel Core Ultra 5 245 paired with the AMD Radeon RX 9070 XT delivers a fundamentally playable experience in Microsoft Flight Simulator, but the data reveals a clear ceiling: at 4K Ultra the combo lands at 55 FPS, while dropping to 1080p Low pushes it to 164 FPS. The scaling pattern from 1080p to 4K indicates a system that becomes progressively GPU-bound at higher resolutions, yet the CPU still exerts meaningful influence at lower settings. This combination ranks 861st out of 3,714 tested combos, placing it in the top 23% of all configurations — a solid mid-to-upper tier result for a flight simulator that stresses both components heavily.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but not catastrophic, and the shape of that curve tells a clear story about where the bottleneck shifts. At Low settings, the average frame rate falls from 164 FPS at 1080p to 133 FPS at 1440p, then to 98 FPS at 4K — a total reduction of 40.2% from 1080p to 4K. This is a relatively gentle decline for a 4x pixel increase, suggesting that at Low settings the CPU is still doing significant work, preventing the GPU from being the sole limiter. The gap between 1080p and 1440p is 31 FPS, while the gap between 1440p and 4K is 35 FPS — nearly linear scaling, which points to a balanced load where neither component is completely saturated.

At Medium settings, the pattern shifts. The 1080p average is 128 FPS, dropping to 103 FPS at 1440p and then to 76 FPS at 4K. The percentage drop from 1080p to 4K here is 40.6%, almost identical to Low settings. However, the min FPS values at Medium — 109 at 1080p, 88 at 1440p, and 65 at 4K — show that frame pacing remains consistent even as the average falls. The max FPS at Medium settings tells a similar story: 147 at 1080p, 119 at 1440p, and 88 at 4K, with the spread between min and max staying around 23-38 FPS across resolutions.

High settings introduce a more pronounced resolution penalty. The average drops from 96 FPS at 1080p to 78 FPS at 1440p to 57 FPS at 4K — a 40.6% reduction from 1080p to 4K, but the absolute numbers are lower across the board. The step from 1440p to 4K is just 21 FPS, while the step from 1080p to 1440p is 18 FPS, indicating that the GPU is becoming the dominant constraint as resolution climbs. This is the first setting tier where 4K dips below the 60 FPS threshold, a critical marker for a flight simulator where smooth panning is essential.

Ultra settings show the steepest relative decline. The 1080p average is 92 FPS, falling to 74 FPS at 1440p and then to 55 FPS at 4K — a 40.2% drop from 1080p to 4K. The 4K Ultra result of 55 FPS is the lowest measured value in the entire dataset, and it confirms that at maximum settings the RX 9070 XT is the limiting component. The near-identical percentage drops across all four settings tiers (40.2-40.6%) is notable: it suggests that Microsoft Flight Simulator's rendering pipeline scales resolution in a consistent manner regardless of preset, with the absolute FPS ceiling set by the preset's overall load.

Settings Recommendations

The measured data points to Medium settings as the optimal balance for this combo, particularly for 1440p and 4K users. At 1440p Medium, the average of 103 FPS with a min of 88 FPS provides a smooth experience with headroom for the complex scenery and weather systems that flight simulators throw at the renderer. The jump from Medium to High at 1440p costs 25 FPS on average (103 to 78), which is a 24.3% performance penalty for what is typically a moderate visual gain in this game. At 4K, Medium delivers 76 FPS average with a 65 FPS minimum — playable, but the min FPS is close to the 60 FPS comfort line.

For 1080p users, High settings at 96 FPS average offer the best experience per the measured rows, since the CPU and GPU have enough headroom to handle the extra visual fidelity without dropping below 60 FPS. The 1080p High result is only 4 FPS below the 1080p Ultra result of 92 FPS, but the gap between High and Medium at 1080p is 32 FPS (96 to 128), making High the sweet spot for those who want quality without sacrificing smoothness.

Ultra settings are difficult to recommend based on the data alone. At every resolution, Ultra delivers the lowest average FPS: 92 at 1080p, 74 at 1440p, and 55 at 4K. The 4K Ultra result falls below 60 FPS, which is a significant concern for a genre where consistent frame delivery matters more than peak numbers. The step from High to Ultra at 4K is only 2 FPS (57 to 55), meaning the additional visual load of Ultra produces almost no measurable frame rate benefit at that resolution — the GPU is already saturated. At 1440p, the High to Ultra gap is 4 FPS (78 to 74), and at 1080p it is 4 FPS (96 to 92). This suggests Ultra is adding graphical complexity that the GPU cannot translate into meaningful frame rate improvements, making High the more sensible choice for most users.

Low settings serve a specific purpose in the data: they show the raw capability of the combo when the GPU is not the primary constraint. At 1080p Low, the 164 FPS average indicates the CPU can push this game well beyond typical display refresh rates, but the visual compromise is not worth it for most flight sim enthusiasts who rely on detailed terrain and cockpit instrumentation.

GPU Role

The AMD Radeon RX 9070 XT is the dominant factor in this combo's performance at higher resolutions. Its 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is directly relevant to Microsoft Flight Simulator's appetite for texture data — the game streams vast amounts of terrain and aircraft detail. The 4K Medium result of 76 FPS and 4K High result of 57 FPS show that the GPU's 4096 shading units and 128 ROPs are being pushed hard, with the pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s determining how quickly the renderer can fill those high-resolution frames.

The GPU's clock behavior is worth noting. The base clock of 1660 MHz, game clock of 2400 MHz, and boost clock of 2970 MHz represent a 79% boost range, and the measured FPS data suggests the card is operating near its boost ceiling in this game. The 4K Ultra result of 55 FPS, compared to 4K High's 57 FPS, indicates that the GPU is hitting a compute limit that cannot be overcome by additional clock headroom — the gap between presets narrows as resolution increases, which is a classic sign of a GPU-bound scenario.

The RX 9070 XT's RDNA 4.0 architecture with 64 RT cores is not a major factor in this game's results, as flight simulators typically rely more on rasterization than ray tracing. The FP32 throughput of 48.66 TFLOPS provides the raw compute for the game's physics and weather simulation, but the measured FPS data shows that memory bandwidth and pixel fill rate are the more likely constraints at 4K. The GPU's percentile ranking of 55 against all GPUs, with an average benchmark score of 13,543, places it in the mid-range of the GPU landscape, yet the measured FPS in this game exceeds what that synthetic ranking might suggest — proof of the game's optimization for AMD hardware.

How This Combo Ranks

The combo rank of 861 out of 3,714 tested configurations places this pairing in the top 23.2% of all combinations, which is a strong result for a mid-range CPU paired with a high-end GPU. The CPU's percentile of 90 against all CPUs (average benchmark score of 48,995) is significantly higher than the GPU's percentile of 55 (average benchmark score of 13,543), indicating that the processor is the stronger component in synthetic benchmarks. However, the measured FPS data tells a different story: the GPU becomes the limiting factor at 4K, while the CPU's headroom is only visible at lower resolutions and settings.

The nearest rivals for the CPU provide context for its contribution. The Intel Core Ultra 5 245 scores within 0.8% of the Intel Core i5-14600K (48,618 vs 48,995), and within 0.5% of the AMD Ryzen 9 7900 (49,228 vs 48,995). This places the Ultra 5 245 in the same performance tier as these processors, meaning the combo's rank is not being dragged down by a weak CPU. The GPU's nearest rivals are all older or lower-tier cards — the AMD Radeon HD 7770M (13,536 vs 13,543) and NVIDIA GeForce GTX 570 (13,515 vs 13,543) — which is a quirk of the benchmark database's scoring, not a reflection of real-world gaming performance. The RX 9070 XT's measured FPS in this game far exceeds what those synthetic scores would suggest.

The rank of 861 out of 3,714 means there are roughly 2,850 combos that perform worse in Microsoft Flight Simulator specifically. This is a meaningful distinction because the game's unique blend of CPU-heavy simulation and GPU-heavy rendering means that many combinations with higher synthetic scores may not translate to better in-game results. The data shows this combo is well-balanced for this title, with neither component so weak that it cripples the other.

CPU Role

The Intel Core Ultra 5 245 brings 14 cores and 14 threads to this pairing, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. The 24 MB of shared L3 cache and 3 MB L2 per core provide the data locality that a simulation game like Microsoft Flight Simulator craves, as the CPU constantly processes flight physics, weather systems, and AI traffic. The 102.4 GB/s memory bandwidth on DDR5 dual-channel support feeds the GPU with sufficient data to avoid stalling the render pipeline.

The CPU's synthetic benchmark scores indicate strong single-thread performance — the Cinebench R23 single-core score of 4,648 and multicore score of 32,924 — which matters for a game that has a primary simulation thread. The PassMark single-thread score of 4,394 and multithread score of 38,706 confirm this pattern. The nearest rival data shows the Ultra 5 245 is essentially tied with the Intel Core i5-14600K (0.8% delta), a processor known for strong gaming performance, which validates that the CPU is not the weak link in this combo.

The measured FPS data supports this conclusion. At 1080p Low, the CPU is able to drive the game to 164 FPS, which is far beyond what most displays can show, indicating that the processor is not a bottleneck at lower resolutions. The drop from 1080p Low to 4K Low — from 164 to 98 FPS — is a 40.2% reduction that is almost entirely attributable to the GPU's workload increasing with pixel count. The CPU's 14 threads are not fully utilized by the game, but the high boost clock of 5.10 GHz ensures that the primary simulation thread has sufficient single-core performance to avoid becoming the limiting factor.

The 65W TDP and 3 nm process node from TSMC mean the CPU runs efficiently, but more importantly for this game, the architecture's memory controller and cache hierarchy are designed to minimize latency — a critical factor for a simulator that must react to every player input and environmental change. The CPU's percentile of 90 against all CPUs places it in the top 10% of all processors, and the measured FPS data confirms that this synthetic strength translates into real-world performance for this specific workload.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 164 FPS, Medium produces 128 FPS with a min of 109 and max of 147, High produces 96 FPS, and Ultra produces 92 FPS. The gap from Low to Medium is 36 FPS, from Medium to High is 32 FPS, and from High to Ultra is 4 FPS — showing diminishing returns as settings increase.

At 2560x1440, the averages are 133 FPS Low, 103 FPS Medium (min 88, max 119), 78 FPS High, and 74 FPS Ultra. The Medium settings show a min-to-max spread of 31 FPS, which is slightly tighter than the 38 FPS spread at 1080p Medium, indicating more consistent frame delivery at the higher resolution. The step from High to Ultra at 1440p is 4 FPS, same as at 1080p.

At 3840x2160, the averages are 98 FPS Low, 76 FPS Medium (min 65, max 88), 57 FPS High, and 55 FPS Ultra. The 4K Medium min FPS of 65 is the only sub-60 measurement at Medium settings across all resolutions, and it suggests that 4K Medium is the practical ceiling for smooth gameplay. The 4K High and Ultra results both fall below 60 FPS, with Ultra being only 2 FPS slower than High — a negligible difference that indicates the GPU is fully saturated at that point.

The data across all resolutions shows a consistent pattern: the FPS drop from 1080p to 1440p averages 23.7% across settings, while the drop from 1440p to 4K averages 26.3%. This slight acceleration in the drop rate at 4K confirms the GPU becomes more dominant as pixel count increases. The Medium settings consistently provide the most stable min-to-max spreads, making it the most predictable preset for this combo. The Ultra settings deliver the lowest FPS at every resolution, and the High settings offer a middle ground that trades 20-25% performance for what is often a modest visual uplift in flight simulators.
