Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding rendering workloads in the benchmark database, and the measured results for the Intel Core Ultra 9 290K Plus paired with the AMD Radeon RX 9070 reveal a configuration that scales predictably with resolution while maintaining remarkable consistency across settings. The data set is complete for all four presets at 1080p, 1440p, and 4K, offering a clear picture of how this hardware combination behaves under varying degrees of graphical stress.

Resolution Scaling

The frame rate progression from 1080p to 4K follows a steep and consistent curve, indicating that the Radeon RX 9070 becomes the primary limiting factor as pixel count increases. At the High preset, average FPS drops from 91 at 1920x1080 to 73 at 2560x1440, a reduction of 18 frames, and then further to 54 at 3840x2160, which represents a 40% decline from the 1080p baseline. This pattern is nearly identical across all settings, with the Medium preset showing 121 FPS at 1080p, 97 at 1440p, and 72 at 4K—demonstrating that the GPU's rendering throughput scales almost linearly with the pixel load.

The Low preset exhibits the most dramatic absolute drop, falling from 155 FPS at 1080p to 125 at 1440p and then to 92 at 4K. That 63-frame difference between 1080p and 4K at Low settings suggests that even when the graphical workload is minimal, the RX 9070 cannot maintain high frame rates at UHD resolutions. Conversely, the Ultra preset shows the smallest absolute scaling gap, moving from 86 FPS at 1080p to 70 at 1440p and 51 at 4K—a total drop of 35 frames, but proportionally less severe than the Low preset's 41% reduction. This implies that at Ultra settings, the game's engine is already pushing the GPU to its limits even at 1080p, so the additional pixel count at higher resolutions has a relatively smaller impact.

The 4K results paint a particularly telling picture. At 4K Ultra, the average FPS of 51 is barely above the 50 FPS threshold that many consider the minimum for smooth gameplay, while 4K High manages 54 FPS. The 4K Medium setting delivers a more playable 72 FPS, and 4K Low reaches 92 FPS. The data suggests that for 4K gaming, the scaling bottleneck is overwhelmingly the GPU's pixel fill rate and memory bandwidth rather than CPU limitations, as the frame rate differences between presets at the same resolution (92 vs 72 vs 54 vs 51) are substantial and directly tied to the GPU's computational load.

GPU Role

The AMD Radeon RX 9070 employs the Navi 48 chip built on TSMC's 4 nm process, with a boost clock of 2520 MHz and a game clock of 2070 MHz. The card features 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 644.6 GB/s. This bandwidth figure is crucial for Flight Simulator, which streams vast amounts of terrain and texture data; the measured FPS results suggest that the 16 GB capacity is not being exhausted at any tested setting, as the scaling from 1080p to 4K shows no sudden cliff that would indicate memory swapping.

The GPU's compute specifications—3584 shading units, 224 texture mapping units, and 128 raster output units—combine to deliver a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s. These figures translate directly into the observed performance: at 4K Ultra, the card sustains 51 FPS, which translates to roughly 5.5 billion pixels processed per second, well below its theoretical pixel rate but still a demanding workload for the game's complex shaders. The FP32 throughput of 36.13 TFLOPS is likely the key differentiator between settings, as the jump from Medium to Ultra at 4K costs 21 FPS (72 to 51), indicating that the additional shader complexity significantly reduces the card's effective efficiency.

The GPU's benchmark scores corroborate the gaming results. The PassMark G3D score of 25381 places it in the 69th percentile of all GPUs, with nearest rivals including the NVIDIA GeForce RTX 2080 SUPER (scoring 24170, a 1.2% difference) and the AMD Radeon RX 6800S (scoring 24063, a 0.8% difference). The 3DMark Steel Nomad DX12 score of 6290 further confirms its mid-range positioning. In the context of Flight Simulator, the card's 56 ray tracing cores and DirectX 12 Ultimate support are present but not heavily utilized, as the game's primary workload is traditional rasterization, which explains why the frame rates are more dependent on raw shader throughput than on advanced features.

Settings Recommendations

Based on the measured FPS rows, the Medium preset emerges as the most balanced choice for this configuration. At 1440p Medium, the average FPS of 97 with a minimum of 83 and maximum of 112 provides a comfortable margin above the 60 FPS target, and the 4K Medium result of 72 FPS is still playable on high refresh rate displays. The data shows that Medium at 4K delivers 18 more FPS than High at the same resolution, a significant improvement that likely comes with only modest visual compromises given the game's engine.

For users prioritizing visual fidelity, the High preset at 1440p (73 FPS average) is the sweet spot, as it offers a 3 FPS improvement over Ultra at the same resolution while presumably retaining most of the graphical enhancements. The Ultra preset at any resolution below 1440p is not recommended, as the 86 FPS at 1080p Ultra is only 5 FPS better than High at 1440p, meaning users could achieve similar frame rates with better image quality by stepping down a setting and up a resolution. The Low preset is generally unnecessary with this hardware, as even 4K Low (92 FPS) exceeds the 1440p High result, indicating that the RX 9070 has sufficient headroom to avoid the most aggressive graphical compromises.

The measured minimum and maximum frame rates for Medium settings provide additional insight. At 1080p Medium, the 103-139 FPS range shows a 36 FPS spread, while at 1440p Medium the range is 83-112 (29 FPS spread), and at 4K Medium it narrows to 61-83 (22 FPS spread). This tightening of the frame time distribution at higher resolutions suggests that the GPU's workload becomes more consistent when it is fully saturated, reducing the impact of scene complexity variations that cause frame drops at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the configuration delivers 155 FPS on Low, 121 FPS on Medium, 91 FPS on High, and 86 FPS on Ultra. The Medium preset's minimum of 103 FPS ensures that even the most demanding scenes stay well above refresh rates up to 100 Hz, while the maximum of 139 FPS approaches the ceiling for 144 Hz displays. The difference between High and Ultra at this resolution is only 5 FPS, suggesting that the Ultra preset's additional effects are not heavily taxing the GPU at 1080p.

Moving to 2560x1440, the results show 125 FPS on Low, 97 FPS on Medium, 73 FPS on High, and 70 FPS on Ultra. The Medium preset's minimum of 83 FPS and maximum of 112 FPS indicate that this resolution is still well within the GPU's comfort zone, though the High and Ultra presets begin to show the strain with sub-75 FPS averages. The gap between High and Ultra narrows to just 3 FPS at this resolution, reinforcing the notion that the Ultra preset's benefits are marginal at 1440p.

At 3840x2160, the frame rates drop to 92 FPS on Low, 72 FPS on Medium, 54 FPS on High, and 51 FPS on Ultra. The Medium preset's minimum of 61 FPS and maximum of 83 FPS demonstrate that 4K gaming is viable but requires careful settings management. The High and Ultra results are nearly identical (54 vs 51 FPS), suggesting that the GPU is hitting a hard computational ceiling at these settings, where additional graphical features have diminishing returns on performance but still impact the visual output.

How This Combo Ranks

The combination of the Intel Core Ultra 9 290K Plus and AMD Radeon RX 9070 ranks 833rd out of 2996 tested combos in Microsoft Flight Simulator, placing it in the 72nd percentile of all configurations. This ranking reflects the GPU's mid-range positioning rather than the CPU's high-end capabilities, as the RX 9070's 69th percentile standing among all GPUs is closely mirrored by the combo's overall performance tier. The CPU's 96th percentile ranking among all processors indicates that it is not the limiting factor in this pairing, leaving headroom for a more powerful GPU to extract additional frame rates.

The GPU's nearest rivals—the NVIDIA GeForce RTX 2080 SUPER and AMD Radeon RX 6800S—have average benchmark scores within 1.2% of the RX 9070, yet the combo ranking of 833 suggests that Flight Simulator may favor the RX 9070's specific architecture characteristics. The CPU's nearest rival, the Intel Core Ultra 9 285K, scores 0.2% higher in average benchmarks, confirming that the 290K Plus is essentially a performance twin to its predecessor in synthetic tests. However, the combo's rank in this game specifically cannot be directly inferred from these synthetic scores, as the game engine's optimization for certain hardware features plays a significant role.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture, built on TSMC's 3 nm process node with a die size of 243 mm² and 17,800 million transistors. Its base clock of 3.70 GHz and boost clock of 5.80 GHz represent a significant frequency range that allows the CPU to handle both lightly-threaded tasks at high clocks and heavily-threaded workloads across its many cores. The 36 MB of shared L3 cache, combined with 3 MB of L2 cache per core, provides ample data locality for the game's streaming assets.

In Flight Simulator, the CPU's role is primarily in physics calculations, AI traffic management, and terrain loading, all of which benefit from the 24 cores and 24 threads. The Cinebench R23 scores—51731 multicore and 7303 singlecore—demonstrate exceptional multi-threaded capability, but the single-core score of 7303 is particularly relevant for the game's main thread that handles world simulation. The PassMark single-thread score of 4823 further confirms the CPU's strength in this area. The 115.2 GB/s memory bandwidth from dual-channel DDR5 ensures that the CPU can feed data to the GPU without becoming a bottleneck, though the measured FPS results suggest that at 4K, the GPU is still the limiting factor.

The CPU's benchmark percentile of 96% versus all CPUs underscores its high-end positioning, yet the measured FPS deltas between 1080p and 4K (which range from 40-63 FPS depending on settings) indicate that the CPU is not constraining performance at any resolution. If the CPU were the bottleneck, we would expect similar frame rates across resolutions, but the data clearly shows a GPU-bound scenario. The CPU's 125W TDP and support for ECC memory suggest it is designed for sustained professional workloads, which aligns with its strong multicore performance that exceeds what Flight Simulator requires—the game likely uses only a fraction of the available cores efficiently.
