# Microsoft Flight Simulator — Intel Core Ultra 5 235HX + NVIDIA GeForce RTX 4070 Mobile

The benchmark data for Microsoft Flight Simulator with the Intel Core Ultra 5 235HX and NVIDIA GeForce RTX 4070 Mobile combination shows a system that scales predictably across resolutions and settings, with the GPU acting as the primary constraint at higher loads. The measured FPS values, all from actual testing of this specific combo, reveal a playable experience at 1080p and 1440p, while 4K demands careful settings selection. The combo sits at rank 1978 out of 3714 tested combinations, placing it in the 53rd percentile among all tested systems — a middle-of-the-pack result that reflects the mobile GPU's limitations in a simulation title known for heavy scene complexity.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and consistent across all four settings presets, indicating that the RTX 4070 Mobile is the dominant limiting factor as pixel count rises. At Low settings, the average frame rate falls from 119 FPS at 1920x1080 to 96 FPS at 2560x1440, then to 71 FPS at 3840x2160 — a total reduction of 48 FPS, or roughly 40% from the 1080p baseline. This scaling pattern is typical for a GPU-bound scenario, where the rendering workload at 4K is roughly four times that of 1080p.

The Medium preset shows a similar relative drop, moving from 93 FPS at 1080p to 75 FPS at 1440p and finally 55 FPS at 4K. The High preset follows the same trajectory: 70 FPS at 1080p, 56 FPS at 1440p, and 42 FPS at 4K. At Ultra settings, the numbers compress further — 66 FPS at 1080p, 54 FPS at 1440p, and 40 FPS at 4K — suggesting that the game's Ultra preset imposes a relatively flat additional cost regardless of resolution, likely due to CPU-side simulation limits in dense scenery areas.

The resolution scaling data indicates that the CPU is not the bottleneck at lower resolutions. At 1080p Low, the system achieves 119 FPS, which is a high value for a flight simulator; the fact that this drops to 71 FPS at 4K Low — a 48 FPS difference — confirms the GPU is the constraining component. If the CPU were the limit, the 1080p and 1440p numbers would cluster closer together. The 1440p-to-4K drop at Low settings is 25 FPS, while the 1080p-to-1440p drop is 23 FPS, showing a nearly linear scaling with pixel count that is characteristic of GPU-bound rendering.

At Medium and High settings, the 4K results (55 and 42 FPS respectively) fall below the 60 FPS threshold, while 1440p stays comfortably above it (75 and 56 FPS). This suggests that for smooth gameplay at 4K, users must step down to Low settings, where 71 FPS is achievable. The 4K Ultra result of 40 FPS is near the edge of playability, and the 4K High result of 42 FPS is only marginally better, indicating that the GPU's 8 GB of VRAM and 256.0 GB/s bandwidth are being pushed hard at this resolution.

Settings Recommendations

The measured data provides clear guidance for each resolution tier. At 1920x1080, all four presets deliver playable frame rates: Low at 119 FPS, Medium at 93 FPS, High at 70 FPS, and Ultra at 66 FPS. The jump from Medium to High costs 23 FPS, while High to Ultra costs only 4 FPS, making High the sweet spot for visual fidelity with a 70 FPS average. Ultra at 1080p is viable for those prioritizing visuals, but the marginal gain over High is minimal.

At 2560x1440, the options narrow. Low delivers 96 FPS, Medium provides 75 FPS, and High drops to 56 FPS. Ultra at 54 FPS is technically playable but sits below the 60 FPS mark. The recommended preset here is Medium, which offers 75 FPS — a good balance between visual quality and smoothness. High at 1440p is acceptable for users who prefer higher detail, but the 56 FPS average means occasional dips below 60 FPS in dense scenery, which can be noticeable in a flight sim where camera panning is common.

At 3840x2160, only Low (71 FPS) reaches the 60 FPS threshold. Medium delivers 55 FPS, High 42 FPS, and Ultra 40 FPS. For 4K users, Low is the only preset that guarantees a smooth experience. Medium at 55 FPS is a compromise for those who want better visuals and can tolerate slight stutter, but the data shows a steep 16 FPS drop from Low to Medium. The High and Ultra presets at 4K are best avoided unless the user is willing to accept frame rates in the low-40s range.

The Medium preset at 1440p (75 FPS) and the High preset at 1080p (70 FPS) are the two best overall combinations of settings and resolution in this dataset, offering the highest frame rates while still maintaining moderate visual quality. The Ultra preset at any resolution provides only marginal gains over High, so the data suggests skipping Ultra unless the system has headroom to spare.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 119 FPS, with no minimum or maximum recorded. Medium settings average 93 FPS, with a minimum of 79 FPS and maximum of 107 FPS — a 28 FPS spread that indicates some scene-to-scene variation. High settings average 70 FPS, while Ultra settings average 66 FPS. The difference between High and Ultra is only 4 FPS, suggesting that the Ultra preset adds minimal additional load at this resolution, possibly due to CPU-side simulation limits that cap the frame rate regardless of GPU effort.

At 2560x1440, the performance drops noticeably. Low settings average 96 FPS, which is still very smooth. Medium settings average 75 FPS, with a minimum of 64 FPS and maximum of 86 FPS — a 22 FPS spread, similar to the 1080p Medium result. High settings average 56 FPS, and Ultra settings average 54 FPS. The gap between High and Ultra narrows to just 2 FPS at 1440p, and the overall range from Low to Ultra is 42 FPS, compared to 53 FPS at 1080p. This compression suggests the GPU is becoming the limiting factor as resolution increases.

At 3840x2160, the frame rates fall into a narrower band. Low settings average 71 FPS, which is still above 60 FPS. Medium settings average 55 FPS, with a minimum of 47 FPS and maximum of 63 FPS — the widest relative spread in the dataset, indicating significant scene complexity variation at 4K. High settings average 42 FPS, and Ultra settings average 40 FPS. The total range from Low to Ultra at 4K is just 31 FPS, showing that even the lowest settings preset cannot fully relieve the GPU pressure at this resolution.

The Medium preset is the only one with recorded minimum and maximum values across all three resolutions. At 1080p, the 79-107 FPS range shows a 28 FPS fluctuation; at 1440p, the 64-86 FPS range shows a 22 FPS fluctuation; at 4K, the 47-63 FPS range shows a 16 FPS fluctuation. This pattern indicates that as resolution increases, the frame rate becomes more stable, further confirming the GPU-bound nature of the workload at higher pixel counts.

GPU Role

The NVIDIA GeForce RTX 4070 Mobile is built on the Ada Lovelace architecture with a 5 nm process node and contains 22,900 million transistors on a 188 mm² die. Its 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, with memory clocks running at 2000 MHz (16 Gbps effective). The GPU has 4608 shading units, 144 texture mapping units, and 48 raster output units, along with 36 ray tracing cores and 144 tensor cores. The boost clock is 1695 MHz, and the TDP is 115 W.

In benchmark results, the RTX 4070 Mobile scores 19587 in PassMark G3D, 109197 in Geekbench OpenCL, and 108367 in Geekbench Vulkan. Its average benchmark score is 27435, placing it in the 73rd percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6700 XT (deltaPct 0), NVIDIA GeForce RTX 3090 (deltaPct -0.5), and NVIDIA RTX PRO 4000 Blackwell (deltaPct 1.1). These comparisons show the mobile GPU performing at a level comparable to desktop-class parts from previous generations.

The GPU's role in Microsoft Flight Simulator is clearly dominant based on the FPS scaling data. The fact that frame rates drop nearly linearly with pixel count — from 119 FPS at 1080p Low to 71 FPS at 4K Low — indicates that the rendering pipeline is saturated by the GPU's compute and memory resources. The 128-bit memory bus and 256.0 GB/s bandwidth are modest for a card in this performance tier, and the 8 GB VRAM capacity may be a limiting factor at 4K Ultra settings, where the game's high-resolution textures and complex scenery can exceed this amount.

The GPU's PassMark G3D score of 19587, combined with its 73rd percentile ranking, suggests it is a capable mid-range mobile part. In this flight simulator, however, the GPU's limitations at 4K are evident: even at Low settings, the system only achieves 71 FPS, and the jump to Medium drops to 55 FPS. This 16 FPS penalty for one settings tier at 4K is significantly larger than the 9 FPS penalty at 1080p (from 119 to 93 FPS), indicating that the GPU's memory bandwidth or texture fill rate becomes a critical constraint at high resolutions.

CPU Role

The Intel Core Ultra 5 235HX is a 14-core, 14-thread processor from the Core Ultra Series 2, based on the Arrow Lake-HX architecture manufactured on a 3 nm process by TSMC. It has a base clock of 2.90 GHz and a boost clock of 5.10 GHz, with a TDP of 55 W. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, and it offers PCIe Gen 5 with 20 lanes.

In synthetic benchmarks, the Core Ultra 5 235HX demonstrates strong performance. Its Cinebench R23 multi-core score is 34731 and single-core score is 4903. The Cinebench R20 scores are 14587 multi-core and 2059 single-core. PassMark tests show a multi-thread score of 40849 and single-thread score of 4683. The average benchmark score is 52073, placing the CPU in the 91st percentile of all CPUs. Its nearest rivals include the AMD EPYC 8124P (deltaPct -0.1), AMD Ryzen 9 5950X (deltaPct 0.2), Intel Core i7-14700 (deltaPct -0.4), and Intel Core i9-13900F (deltaPct 0.7).

The CPU's role in this game is secondary to the GPU, as evidenced by the FPS scaling data. At 1080p Low, the system reaches 119 FPS, which is below the CPU's potential maximum given its high single-thread score of 4903 in Cinebench R23. The fact that frame rates drop consistently with resolution increases — rather than plateauing at a CPU-determined ceiling — confirms the GPU is the bottleneck. However, the CPU's 14 cores and 14 threads (with no hyperthreading) may affect performance in heavily populated areas or with AI traffic, though the measured data does not distinguish between these scenarios.

The CPU's 91st percentile ranking and its proximity to desktop parts like the Ryzen 9 5950X and Core i7-14700 suggest it has ample headroom for this title. The 24 MB of L3 cache and 102.4 GB/s memory bandwidth are sufficient for the game's streaming data requirements, and the 5.10 GHz boost clock provides strong single-threaded performance for the game's main simulation thread.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235HX and NVIDIA GeForce RTX 4070 Mobile ranks 1978 out of 3714 tested combos for Microsoft Flight Simulator. This placement in the 53rd percentile means the system performs better than roughly half of all tested configurations, but it is not an outlier in either direction. The rank reflects the GPU's mid-range positioning (73rd percentile among all GPUs) rather than the CPU's strong showing (91st percentile among all CPUs), confirming that the GPU is the limiting factor in this pairing.

The CPU's benchmark scores place it near the top of its class, with a Cinebench R23 multi-core score of 34731 that rivals desktop parts like the Intel Core i7-14700 (deltaPct -0.4) and AMD Ryzen 9 5950X (deltaPct 0.2). The GPU, by contrast, sits at a more modest level, with its PassMark G3D score of 19587 and average benchmark score of 27435 placing it near the AMD Radeon RX 6700 XT (deltaPct 0) and NVIDIA GeForce RTX 3090 (deltaPct -0.5). This imbalance — a high-end CPU paired with a mid-range GPU — is typical of mobile gaming systems where thermal and power constraints limit the GPU more than the CPU.

The combo's rank of 1978 out of 3714 indicates that while this system can run Microsoft Flight Simulator at playable frame rates across most settings and resolutions, it does not excel in the way the CPU's 91st percentile ranking might suggest. The GPU's 73rd percentile ranking and its 8 GB VRAM capacity are the primary factors holding the system back, particularly at 4K where even Low settings only produce 71 FPS. For users targeting 1080p or 1440p gaming, this combo is well-suited, but for 4K enthusiasts, the data shows it is only marginally viable at the lowest settings preset.
