Microsoft Flight Simulator

The Intel Core i5-14600K pairs 14 cores with 20 threads, a configuration that leverages a hybrid architecture of performance and efficiency cores. Its base clock of 3.50 GHz can reach a boost of 5.30 GHz, and the processor carries 24 MB of shared L3 cache. In synthetic benchmarks, this CPU achieves a Cinebench R23 multi-core score of 24491 and a single-core score of 2064, with a Geekbench single-core result of 2491. The data suggests that Microsoft Flight Simulator, being a simulation title that often relies on strong single-thread performance for its core flight model and scenery processing, benefits from this processor’s high boost clocks. The 90th percentile ranking against all CPUs indicates that this is a top-tier part for general processing tasks, and its average benchmark score of 48618 places it in close contention with rivals like the Intel Xeon Gold 5318H, which scores 48698 (a 0.2% difference). This proximity in average scores implies that in CPU-bound scenarios, the i5-14600K will perform nearly identically to that Xeon, despite the Xeon being a server-class chip. The 20 threads provide ample headroom for background simulation systems, and the 5.30 GHz boost clock is particularly relevant for a game where frame pacing can depend on the speed of a single primary thread handling the aircraft's avionics and physics. The processor’s memory support for both DDR4 and DDR5 offers flexibility, though the measured FPS data does not specify which memory type was used, making it difficult to isolate the CPU’s memory bandwidth contribution to the final frame rates.

The NVIDIA GeForce RTX 4080 SUPER is the other half of this combination, built on the Ada Lovelace architecture with a 5 nm process from TSMC. It comes equipped with 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 736.3 GB/s. The GPU’s boost clock is rated at 2550 MHz, and it houses 10240 shading units alongside 80 RT cores and 320 tensor cores. For raw compute, it delivers 52.22 TFLOPS of FP32 performance. In the context of Microsoft Flight Simulator, the 16 GB VRAM buffer is a critical asset; the game is known for streaming vast amounts of terrain and photogrammetry data, and the data shows that the GPU’s percentile ranking is 86th among all GPUs. Its average benchmark score of 54209 is remarkably close to the non-SUPER RTX 4080, which scores 54247, a delta of only -0.1%, suggesting that in this specific title, the SUPER variant’s slight clock advantages may not translate into meaningful FPS gains over its predecessor. The GPU’s DirectX 12 Ultimate support aligns with the game’s modern rendering requirements, and the 736.3 GB/s memory bandwidth ensures that texture streaming at high resolutions does not become a bottleneck. The 45,900 million transistors on a 379 mm² die indicate a dense, power-hungry design, but the measured FPS results show it handles the simulator’s load effectively, particularly when paired with a CPU strong enough to feed it.

Resolution scaling reveals the shifting balance between CPU and GPU load. At 1920x1080 with Low settings, the combo achieves 209 FPS, which drops to 169 FPS at 2560x1440 and further to 125 FPS at 3840x2160. This pattern indicates that at 1080p, the system is heavily CPU-bound, as the i5-14600K’s strong single-thread performance pushes frame rates high, but the GPU is not yet saturated. The transition from 1080p to 1440p results in a 40 FPS drop (209 to 169), a 19% decrease, which is relatively modest and suggests that the GPU is starting to take on more work. Moving from 1440p to 4K, the FPS falls from 169 to 125, another 44 FPS drop (26% decrease), showing that the RTX 4080 SUPER’s rendering load is increasing significantly. However, the most telling data point is the Ultra preset, where the 4K average is 69 FPS, only 5 FPS lower than the 1440p Ultra average of 94 FPS (a 27% drop). This suggests that at Ultra settings, the game becomes more GPU-bound, but the CPU still has enough headroom to maintain playable frame rates. The 1080p Ultra result of 117 FPS compared to the 4K Ultra result of 69 FPS indicates a 48 FPS difference (41% drop), which is substantial, but the fact that the 4K Ultra score remains above 60 FPS shows the pair can handle the highest resolution, though with less headroom for demanding scenery.

The measured FPS breakdown provides a detailed look at performance across resolutions and settings. At 3840x2160, the Ultra preset yields an average of 69 FPS, while High settings increase this to 73 FPS, Medium jumps to 97 FPS, and Low reaches 125 FPS. The Medium preset at 4K shows a minimum FPS of 82 and a maximum of 111, indicating a stable frame time distribution. Moving to 2560x1440, the averages are 94 FPS (Ultra), 99 FPS (High), 131 FPS (Medium), and 169 FPS (Low). The Medium preset at 1440p exhibits a minimum of 112 FPS and a maximum of 151 FPS, which is a tighter range than the 4K Medium results, suggesting better consistency at this resolution. At 1920x1080, the numbers climb to 117 FPS (Ultra), 123 FPS (High), 163 FPS (Medium), and 209 FPS (Low). The 1080p Medium preset shows a minimum of 138 FPS and a maximum of 187 FPS, which is the widest spread among the measured presets, indicating some frame variance, though the average remains high. Notably, the jump from High to Ultra at each resolution is relatively small (e.g., 73 to 69 FPS at 4K, 99 to 94 FPS at 1440p, 123 to 117 FPS at 1080p), suggesting that the Ultra preset’s additional graphical effects have a diminishing impact on performance relative to the step from Medium to High. The lack of bottleneck at 1080p Low, where 209 FPS is achieved, suggests the CPU is not limiting the GPU in this scenario, but the scaling from Low to Medium (209 to 163 FPS at 1080p) shows a significant 46 FPS drop, indicating that the GPU is becoming more involved as settings increase.

This combination ranks 251st out of 3714 tested combos in Microsoft Flight Simulator, placing it in the top 7% of all configurations. This ranking is a strong indicator that the i5-14600K and RTX 4080 SUPER are well-matched for this specific title, as the combo outperforms the vast majority of alternatives. The CPU’s percentile of 90 and the GPU’s percentile of 86 are both high, but the combo’s rank suggests that the synergy between the two is particularly effective for flight simulation, which may favor the CPU’s single-thread speed and the GPU’s large memory buffer. The data implies that while neither component is the absolute fastest in its class, their combination avoids obvious bottlenecks, as evidenced by the relatively smooth scaling across resolutions. The close rival scores for the CPU (e.g., AMD EPYC 4345P at 48470, a 0.3% difference) and GPU (e.g., AMD Radeon Pro W5700X at 54828, a -1.1% difference) do not appear in the measured FPS data, so it is unclear how those alternatives would perform in this game, but the high combo rank suggests this pairing is a safe bet for high frame rates.

Based on the measured rows, the Medium preset at 2560x1440 offers the best balance of performance and visual quality, delivering an average of 131 FPS with a minimum of 112 FPS. This ensures that the frame rate rarely dips below 100 FPS, which is ideal for a simulator where smooth panning over terrain is crucial. At 4K, the Medium preset’s 97 FPS average is also respectable, but the 1440p Medium result provides more headroom for complex scenery or add-ons that might tax the system further. The High preset at 1440p (99 FPS) is nearly identical to 4K Medium (97 FPS), suggesting that the GPU is the limiting factor when pushing higher settings at lower resolutions. For users with a 1080p display, the Ultra preset at 117 FPS is viable, but the step from High to Ultra (123 to 117 FPS) is marginal, so High might be preferable for slightly better frame pacing. The Low preset, while achieving 209 FPS at 1080p, sacrifices too much visual fidelity for a flight simulator where terrain detail is essential. The data suggests that Medium settings provide the most consistent frame times across all resolutions, as evidenced by the available min/max FPS values, and this preset is likely the sweet spot for this hardware.

Q: What is the best resolution for this combo if the user wants to stay above 100 FPS?

A: The 2560x1440 Medium preset is the only measured configuration that maintains an average above 100 FPS (131 FPS) with a minimum of 112 FPS. At 4K, the Medium preset averages 97 FPS, which falls short of the 100 FPS mark.

Q: How does the RTX 4080 SUPER compare to the regular RTX 4080 in this game?

A: The average benchmark score for the RTX 4080 SUPER is 54209, while the RTX 4080 scores 54247, a delta of -0.1%. This indicates the SUPER is essentially on par with the regular 4080 in synthetic tests, and the measured FPS data does not include a comparison for the standard 4080.

Q: Is the CPU or GPU the limiting factor at 1080p Low settings?

A: At 1920x1080 Low, the combo achieves 209 FPS. This high frame rate suggests the GPU is not being fully utilized, meaning the CPU’s performance is the primary driver, as the i5-14600K’s high boost clock allows for rapid frame generation.

Q: What is the frame rate difference between High and Ultra settings at 4K?

A: At 3840x2160, the High preset averages 73 FPS, while the Ultra preset averages 69 FPS. This is a difference of only 4 FPS, indicating that the Ultra preset’s additional visual effects have a minimal impact on performance at this resolution.

Q: How does this combo rank compared to all other tested combinations?

A: The combo ranks 251st out of 3714 tested combinations in Microsoft Flight Simulator, placing it in the top 7% of all configurations tested.

Q: Does the game benefit more from the CPU’s single-core or multi-core performance?

A: The CPU’s Cinebench R23 single-core score is 2064, which is strong, and the multi-core score is 24491. The high 1080p Low FPS of 209 suggests single-core performance is critical, but the 20 threads ensure that background simulation tasks do not cause stutters, as evidenced by the stable Medium preset min FPS values.
