Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the heaviest simulation workloads in the benchmark database, and pairing it with the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5070 Ti Mobile gives a clear picture of where a modern high-end mobile combo lands in this 2020-released flight sim. The data shows a machine that is decisively GPU-bound at higher resolutions, with framerates that fall from 138 FPS at 1080p Low to 46 FPS at 4K Ultra — a spread that says far more about the graphics card than the 16-core Dragon Range CPU sitting behind it. Across all tested combinations in the database, this pairing ranks 1405th of 3714 in this game, placing it in the top half but not the elite tier for this title.

Resolution Scaling

The scaling story here is straightforward: as resolution climbs, framerates compress, and the GPU becomes the limiting component. At 1920x1080, the combo delivers 138 FPS on Low, 108 FPS on Medium, 81 FPS on High, and 77 FPS on Ultra. Move to 2560x1440 and those numbers become 112, 87, 65, and 62 FPS respectively. At 3840x2160 the range tightens further to 82, 64, 48, and 46 FPS.

The pattern is diagnostic. Between 1080p and 1440p, Ultra drops by roughly a fifth — from 77 to 62 FPS. Between 1440p and 4K, it drops again from 62 to 46 FPS. The fact that High and Ultra results nearly converge at 4K (48 versus 46 FPS, a gap of just two frames) indicates that the RTX 5070 Ti Mobile is saturated at native 4K; additional visual settings barely register because the card is already at its pixel-throughput ceiling. At 1080p, by contrast, the Low-to-Ultra spread is much wider — 138 down to 77 FPS — which shows settings still matter when the GPU has headroom, and it also hints that the CPU or game engine itself begins to impose a floor as settings rise, since even a 61-point reduction in demands at 1080p Low only yields 138 FPS rather than something dramatically higher.

That 1080p Medium figure of 108 FPS, with a minimum of 92 and a maximum of 124, is arguably the sweet spot in the dataset: it demonstrates that the pairing can sustain triple-digit averages with frame-to-frame consistency (the recorded range spans 92 to 124) once settings are moderated. The same Medium preset at 1440p records 87 FPS average with a low of 74 and a high of 100 — a tighter band in absolute terms, consistent with a GPU working harder and less able to spike upward.

In short, the data indicates this is a GPU-limited configuration at 1440p and 4K in Microsoft Flight Simulator, and only modestly CPU- or engine-limited at 1080p where framerates flatten at the top end.

GPU Role

The RTX 5070 Ti Mobile is a Blackwell 2.0 part built on TSMC's 5 nm process, with the GB205 chip packing 31,100 million transistors into a 263 mm² die — a transistor density of 118.3 million transistors per square millimetre. Its specification profile explains the framerate behavior seen above. The card runs at a base clock of 847 MHz with a 1447 MHz boost, and its memory subsystem is 12 GB of GDDR7 on a 192-bit bus, running at 1750 MHz (28 Gbps effective) for a total of 672.0 GB/s of bandwidth.

That memory configuration is central to the 4K results. Microsoft Flight Simulator is a texture- and streaming-heavy title, and at native 4K the card's 5888 shading units, 184 TMUs, and 80 ROPs are pushed hard. The card's theoretical ceilings — 115.8 GPixel/s of pixel fill and 266.2 GTexel/s of texture fill, with 17.04 TFLOPS of FP32 compute — are sufficient for the High and Ultra results recorded here, but the near-identical 48 and 46 FPS averages at 4K High and Ultra show those ceilings being reached. Ray tracing hardware (46 RT cores) and tensor hardware (184 tensor cores) exist on the chip, but the measured dataset records no upscaling or frame-generation results, so the raw rasterization numbers are what this page reports.

In the broader GPU landscape, the RTX 5070 Ti Mobile sits in the 80th percentile against all GPUs tested, with an average benchmark score of 35435. Its nearest rivals in the database are an eclectic set: the NVIDIA Quadro GV100 at an average score of 35520 (a delta of -0.2 percent), the AMD Radeon Pro Duo at 35860 (-1.2 percent), the NVIDIA A2 at 34690 (+2.1 percent), and the NVIDIA T1000 at 36289 (-2.4 percent). Against that field, the mobile card is essentially dead-center — slightly ahead of the A2, marginally behind the professional Quadro and T1000 parts. That mid-high placement maps directly onto its Flight Simulator results: capable of 4K gameplay, but not at high-refresh rates with demanding settings.

The card's compute benchmarks reinforce the picture. It scores 143870 in Geekbench OpenCL and 139213 in Geekbench Vulkan, with a PassMark G3D score of 24004 and a GPU compute score of 10101. These are strong mobile figures, and they underwrite the 1080p Medium triple-digit average, but the 60 W TDP of this mobile part ultimately caps what it can deliver at 4K Ultra in a sim that punishes GPU memory and fill rate.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K?

A: Yes, with caveats. At 3840x2160 the pairing averages 82 FPS on Low, 64 FPS on Medium, 48 FPS on High, and 46 FPS on Ultra. High-detail 4K play sits right at the edge of smooth for a flight sim, where consistent frames matter more than raw speed.

Q: What is the best resolution and settings combination in the measured data?

A: For balanced play, 2560x1440 Medium stands out: 87 FPS average with a minimum of 74 and a maximum of 100. For maximum fluidity, 1920x1080 Low delivers 138 FPS average.

Q: Is the CPU or the GPU the bottleneck in this game?

A: The GPU. Framerates drop steadily as resolution rises and the High/Ultra results converge at 4K, both signatures of graphics-card saturation. The Ryzen 9 8945HX, in the 95th percentile of all CPUs tested, is not the constraint.

Q: How does this pairing rank against other tested combinations in this game?

A: It ranks 1405th out of 3714 tested combos in Microsoft Flight Simulator — the top half of the database, but not among the fastest configurations recorded for this title.

Q: Does the 12 GB of VRAM matter at 4K?

A: The card's 12 GB of GDDR7 on a 192-bit bus delivers 672.0 GB/s of bandwidth, and the 4K results show the card reaching its limits there — the two-frame gap between 4K High and Ultra indicates the memory subsystem and fill rates are fully loaded at native 4K.

Q: What framerates should be expected at 1080p?

A: 138 FPS on Low, 108 FPS on Medium (minimum 92, maximum 124), 81 FPS on High, and 77 FPS on Ultra.

Measured FPS Breakdown

All figures below are measured, not estimated — the dataset flags dataIsMeasured as true. Averages are listed for every resolution and preset; minimum and maximum framrates were recorded only for the Medium preset.

At 1920x1080:

• Low: 138 FPS average
• Medium: 108 FPS average (minimum 92, maximum 124)
• High: 81 FPS average
• Ultra: 77 FPS average

At 2560x1440:

• Low: 112 FPS average
• Medium: 87 FPS average (minimum 74, maximum 100)
• High: 65 FPS average
• Ultra: 62 FPS average

At 3840x2160:

• Low: 82 FPS average
• Medium: 64 FPS average (minimum 54, maximum 74)
• High: 48 FPS average
• Ultra: 46 FPS average

Reading across presets: the Low-to-Ultra penalty is 61 frames at 1080p (138 to 77), 50 frames at 1440p (112 to 62), and 36 frames at 4K (82 to 46). The shrinking absolute penalty as resolution rises confirms that the GPU is progressively the ceiling — at 4K there is simply less headroom for settings to trade against. The Medium-preset frame bands are worth noting for sim players sensitive to stutter: at 4K Medium the recorded range is 54 to 74 FPS, meaning dips into the mid-50s occur even at moderate settings on this hardware.

How This Combo Ranks

Within Microsoft Flight Simulator specifically, the Ryzen 9 8945HX plus RTX 5070 Ti Mobile combination ranks 1405th out of 3714 tested configurations. That places it comfortably in the upper half of the database for this game — a meaningful result given Flight Simulator's reputation as one of the most demanding titles in the catalog, where leaderboard position is harder to earn than in lighter genres.

Context from the component-level rankings sharpens the picture. The CPU sits in the 95th percentile versus all CPUs, with an average benchmark score of 76212; the GPU sits in the 80th percentile versus all GPUs, averaging 35435. The combo's in-game rank — top half, but not top tier — tracks more closely with the GPU's percentile than the CPU's. That is expected behavior for this title, which is far more graphics-constrained than CPU-constrained at the resolutions tested, and it means the ranking here reflects the RTX 5070 Ti Mobile's standing rather than any shortfall from the Ryzen 9.

Among the CPU's nearest rivals by average score are the Intel Core Ultra 9 285HX at 76155 (delta 0.1 percent), the AMD EPYC Embedded 8224P at 76492 (delta -0.4 percent), the AMD Ryzen Threadripper PRO 9945WX at 76513 (delta -0.4 percent), and the AMD Ryzen 9 9950X3D at 75779 (delta 0.6 percent). The 8945HX is statistically inseparable from that group, and in a GPU-bound game like this one, swapping between them would be expected to leave the measured framerates essentially unchanged.

CPU Role

The Ryzen 9 8945HX is a Dragon Range part built on Zen 4 architecture, fabricated by TSMC on a 5 nm process. It carries 16 cores and 32 threads — the most threads of any mainstream mobile configuration class — with a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The dual-die design spans 2x 71 mm² of silicon carrying 13,140 million transistors, and each core gets 64 KB of L1 and 1 MB of L2 cache, backed by a shared 64 MB of L3. Memory support is DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth, and the platform provides PCIe Gen 5 with 28 lanes from the CPU.

In Microsoft Flight Simulator, the CPU's role is to feed the simulation itself — flight dynamics, world streaming, and air traffic — rather than to drive framerates at higher resolutions. The data bears this out: the 1080p results, where the CPU would matter most, top out at 138 FPS on Low, and the spread between presets at that resolution suggests the game's main-thread behavior and engine logic, not raw multi-core throughput, sets the ceiling. The 8945HX's single-thread credentials are strong — 607 in Cinebench R15 single-core, 2532 in R20, 6030 in R23, and 3907 in PassMark single-thread — and its 5.40 GHz boost clock is what matters most for a sim that leans on one fast thread.

Its multi-core muscle is nonetheless elite for a mobile part: 4305 in Cinebench R15 multi-core, 17939 in R20, 42713 in R23, and a PassMark multithread score of 51405, complemented by physics at 2168, integer math at 195180, floating point at 117453, and data compression at 677755. That headroom is surplus to requirement for framerates in this title, but it is exactly what keeps background simulation, streaming, and tooling from impinging on the game. The chip's 55 W TDP and mobile market segment complete the picture of a laptop-class flagship.

The verdict from the data: in this pairing, the Ryzen 9 8945HX is more CPU than Microsoft Flight Simulator needs, and the RTX 5070 Ti Mobile is precisely the component setting the pace. Players targeting 1080p or 1440p Medium will get triple-digit or near-triple-digit performance; players committed to native 4K should expect 46 to 64 FPS depending on preset, with dips into the mid-50s recorded even at Medium.
