Microsoft Flight Simulator

Microsoft Flight Simulator places an unusual burden on both processor and graphics card, demanding high single-thread CPU throughput for flight model and scenery simulation while simultaneously pushing massive geometry and texture loads through the GPU. The Intel Core i7-12700K paired with the AMD Radeon RX 9070 XT demonstrates a balanced but resolution-sensitive profile, where the frame rate curve across settings reveals which component becomes the bottleneck as visual fidelity climbs. This combination ranks 480th out of 1795 tested combos, placing it in the upper third of all systems evaluated, a solid position for a flight sim that rewards both strong CPU and GPU resources.

Resolution Scaling

The transition from 1080p to 4K shows a steady, predictable decline in frame rates, but the shape of that decline changes depending on the quality preset. At High settings, the average frame rate drops from 97.3 FPS at 1920x1080 to 76 FPS at 2560x1440, then falls further to 59 FPS at 3840x2160. That represents a 39% reduction from 1080p to 4K, a substantial hit that indicates the GPU is being increasingly taxed as pixel count rises. The step from 1080p to 1440p costs 21.3 FPS, while the step from 1440p to 4K costs another 17 FPS, showing a slightly accelerating penalty at higher resolutions.

At Low settings, the scaling pattern reveals a different story. The system achieves 165.1 FPS at 1080p, drops to 130.8 FPS at 1440p, and still manages 93.1 FPS at 4K. The percentage decline from 1080p to 4K is 43.6%, which is actually steeper than at High settings. This suggests that when the visual load is light, the CPU is better able to feed frames, but the GPU still becomes the limiting factor at 4K even with minimal graphics work. The data indicates that at Low settings, the RX 9070 XT is capable of pushing well over 160 FPS at 1080p, but the 4K result of 93.1 FPS shows the raw pixel throughput requirement still dominates.

Ultra settings produce the most dramatic scaling. At 1080p, the system delivers 89.9 FPS, which drops to 75.7 FPS at 1440p and 54.9 FPS at 4K. The 1080p to 4K decline is 38.9%, nearly identical to the High preset drop. Interestingly, the gap between High and Ultra at 1080p is only 7.4 FPS, but at 4K that gap widens to 4.1 FPS. This indicates that at lower resolutions, the CPU is able to keep up with the added GPU workload, but at 4K the GPU becomes the clear limiting factor, compressing the differences between presets. The Medium preset sits predictably between Low and High, with 125.5 FPS at 1080p, 99.8 FPS at 1440p, and 71.5 FPS at 4K.

The overall pattern suggests that this combo is GPU-limited at 4K across all settings, but at 1080p the CPU plays a more significant role. The fact that Ultra at 1080p (89.9 FPS) is only slightly behind High at 1440p (76 FPS) shows that resolution scaling is not linear, and that the RX 9070 XT has enough headroom at 1080p to handle the most demanding presets without collapsing. Flight simulators typically show strong CPU scaling at lower resolutions, and the data here confirms that the i7-12700K is able to maintain high frame rates until the pixel count becomes overwhelming.

CPU Role

The Intel Core i7-12700K is a 12-core, 20-thread processor based on the Alder Lake architecture, built on Intel's 10 nm process. Its base clock of 3.60 GHz and boost clock of 5.00 GHz provide the kind of high single-thread performance that Microsoft Flight Simulator demands for its complex flight dynamics and scenery streaming. The processor's benchmark results reflect this strength: it scores 4128 in Cinebench R23 single-core and 29241 in multi-core, with a Geekbench single-core score of 2561 and multi-core of 13892. These figures indicate a processor that excels at both lightly threaded tasks and heavily parallel workloads, making it well-suited to a game that uses multiple threads for different subsystems.

The L3 cache of 25 MB shared across all cores helps with the large datasets that Flight Simulator streams from disk, while the dual-channel DDR4 and DDR5 memory support allows for flexible system configurations. The processor's 3DMark scores show a clear scaling pattern: single-thread score is 1043, doubling to 2065 at 2 threads, nearly doubling again to 4011 at 4 threads, and reaching 7202 at 8 threads before topping out at 9979 at max threads. This scaling curve indicates that the processor maintains efficiency as thread count increases, which is important for Flight Simulator's use of multiple worker threads for terrain loading and traffic simulation.

In the context of this game, the CPU's role becomes evident when comparing frame rates at 1080p across different presets. At Low settings, the system hits 165.1 FPS, which is a high enough frame rate that the CPU is likely the limiting factor, as the GPU should be capable of more. The fact that Ultra at 1080p only drops to 89.9 FPS, a 45.5% reduction from Low, suggests that the CPU is still able to feed the GPU adequately even with the most demanding settings. The processor's percentile ranking of 89 among all CPUs indicates it outperforms the vast majority of available processors, and its nearest rivals — the AMD Ryzen 7 PRO 5845 at -0.3%, the Intel Core i7-13700T at +0.6%, the Intel Core i5-14500HX at -0.7%, and the Intel Core i7-13800H at +0.8% — are all extremely close in average benchmark score, showing that the i7-12700K sits at a performance plateau where small differences are negligible.

GPU Role

The AMD Radeon RX 9070 XT is a RDNA 4.0 architecture graphics card built on TSMC's 4 nm process, with a die size of 357 mm² and 53.9 billion transistors. Its 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is crucial for Flight Simulator's high-resolution textures and streaming terrain data. The GPU's boost clock of 2970 MHz and game clock of 2400 MHz, combined with 4096 shading units and 128 ROPs, give it substantial raw compute power, reflected in its FP32 performance of 48.66 TFLOPS. The card's 3DMark Steel Nomad DX12 score of 7260 and Passmark G3D score of 26795 place it in the 82nd percentile of all GPUs, a strong showing for a modern high-end card.

The GPU's role in this game becomes clear when examining the 4K results across presets. At 4K Low, the system achieves 93.1 FPS, which is a respectable frame rate, but the drop from 1080p Low (165.1 FPS) is a 43.6% reduction. This indicates that even at Low settings, the 4K pixel workload is substantial enough to significantly tax the GPU. At 4K Ultra, the frame rate falls to 54.9 FPS, which is below the 60 FPS threshold that most players consider smooth. The difference between 4K Low and 4K Ultra is 38.2 FPS, showing that the GPU's performance scales strongly with settings at this resolution.

The RX 9070 XT's memory configuration is particularly relevant for this game. Flight Simulator is known for using large amounts of VRAM at high settings, and the 16 GB capacity ensures that the card does not run into memory limits, which would cause stuttering or texture pop-in. The 644.6 GB/s bandwidth provides sufficient throughput for the constant streaming of scenery data. The GPU's nearest rivals — the AMD Radeon Pro 575 at -0.1%, the NVIDIA RTX A500 Mobile at +0.2%, the AMD Radeon Pro 575X at -0.5%, and the AMD Radeon RX Vega 64 at -0.6% — are all within 0.6% of its average benchmark score, indicating that the RX 9070 XT is at a performance level where direct comparisons are nearly identical.
