Microsoft Flight Simulator

The AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 4080 combination delivers a compelling 4K experience in Microsoft Flight Simulator, but the data reveals a clear shift in performance bottlenecks as resolution scales. This pairing ranks in the top 8% of all tested combos, and the measured frames per second show a system that is heavily CPU-bound at lower resolutions before transitioning to a GPU-bound state at 4K.

Resolution Scaling

The performance trajectory from 1080p to 4K is steep and highly informative. At 1920x1080 with Low settings, the combo produces a commanding 187 FPS average. This figure drops to 170 FPS at 2560x1440 and then to 125 FPS at 3840x2160, representing a 33% reduction in frame rate from 1080p to 4K at the Low preset. The scaling pattern indicates that at 1080p, the CPU is the primary limiting factor, as the GPU has ample headroom to render frames far faster than the processor can feed it.

The gap between resolution tiers narrows as settings increase, which is typical for a flight simulator with complex rendering workloads. At High settings, the average FPS falls from 123 at 1080p to 99 at 1440p and finally to 73 at 4K. This 40.6% drop from 1080p to 4K at High settings shows how the GPU becomes progressively more dominant in determining final frame rates. The Ultra preset tells a similar story: 117 FPS at 1080p descends to 95 FPS at 1440p and bottoms out at 70 FPS at 4K.

The Medium preset offers the only complete data set with minimum and maximum frame times. At 1080p Medium, the average sits at 164 FPS with a minimum of 139 FPS and a maximum of 188 FPS. Moving to 1440p Medium, the average drops to 132 FPS with a spread from 112 to 152 FPS. At 4K Medium, the figures compress further: 97 FPS average with a minimum of 83 and a maximum of 112 FPS. The narrowing of the minimum-to-maximum spread at higher resolutions suggests that frame pacing becomes more consistent when the GPU is the bottleneck, as the CPU no longer introduces sporadic stalls.

The data makes one thing clear: the RTX 4080 is the star at 4K, but its full potential is masked at 1080p. The difference between 1080p Low and 4K Low is 62 FPS, while the difference between 1080p Ultra and 4K Ultra is just 47 FPS. This indicates that at lower resolutions, the Ryzen 7 5800XT's eight cores are working hard to keep up, and the GPU's massive compute resources are underutilized.

How This Combo Ranks

Within the database of 3,714 tested combinations, this specific pairing of the AMD Ryzen 7 5800XT with the NVIDIA GeForce RTX 4080 achieves a rank of 283. This places it in the top 7.6% of all combos tested, a strong showing for a desktop platform built on the AM4 socket. The rank reflects the balanced nature of the pairing, where a high-end GPU meets a capable mid-generation CPU refresh.

The CPU itself holds an 81st percentile ranking among all processors, while the GPU sits at the 86th percentile among all graphics cards. This near-parity in relative performance is reflected in the combo's overall standing. It is notably the CPU's nearest rivals—the AMD Ryzen 7 7840H, Ryzen 7 8845HS, Ryzen 7 7840HS, and Ryzen 5 9600X—all have average benchmark scores within a 0.6% delta of the 5800XT. This suggests that the processor is performing exactly as expected for its class, with no unusual uplift or deficit in synthetic tests.

For the GPU, the nearest rival is the RTX 4080 SUPER, which scores a mere 0.1% higher on average. This effectively means the two cards are performance equivalents in most workloads. The AMD Radeon Pro W5700X trails by 1.1%, and the Radeon RX 6750 GRE 12 GB and Radeon 8060S are 2.6% and 2.7% behind, respectively. The fact that the RTX 4080 sits so close to its SUPER variant in the database reinforces that this combo's rank of 283 is driven by a GPU that punches at the top of its tier.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer, and built on a 7 nm process at TSMC. It features a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 32 MB shared L3 cache. The processor supports DDR4 memory in a dual-channel configuration, delivering 51.2 GB/s of memory bandwidth. Released on 2024-07-30 with a launch MSRP of $249, this chip is a refresh of the 5000 series that brings higher boost clocks to the aging AM4 platform.

In Microsoft Flight Simulator, the CPU's role is pivotal at lower resolutions. The benchmark data shows that at 1080p Low, the system achieves 187 FPS, which is 49.6% higher than the 4K Low result of 125 FPS. This delta is almost entirely attributable to CPU limitations. The simulation engine of the game is known for heavy single-threaded and moderate multi-threaded usage, and the 5800XT's single-thread performance is adequate but not class-leading. The 3DMark single-thread score of 959 and the Cinebench R23 single-core score of 3,359 indicate solid IPC, yet the 4.80 GHz boost clock is the ceiling for this chip.

The multi-threaded scores show the 8-core design has headroom: Cinebench R23 multi-core hits 23,794, and Passmark multi-thread reaches 28,053. However, in this game, the scaling from 1080p to 1440p at Low settings (187 to 170 FPS) suggests that even with all 16 threads active, the CPU is still the constraint. The 1440p to 4K transition at Low (170 to 125 FPS) shows a much larger drop, indicating that the GPU begins to take over as the limiting factor somewhere in that resolution range.

The processor's 105W TDP and AM4 socket compatibility are notable, but the benchmark results are what matter. The 16 threads provide enough parallelism for the game's background tasks, such as terrain streaming and physics calculations, while the high boost clock handles the main rendering thread. The combination of 8 cores and a 4.80 GHz boost clock places this CPU in a sweet spot for flight simulators, where both single-thread speed and multi-thread capacity are valuable.

GPU Role

The NVIDIA GeForce RTX 4080 is a powerhouse built on the Ada Lovelace architecture, featuring the AD103 chip fabricated on a 5 nm process at TSMC. It boasts 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines. The card operates with a base clock of 2205 MHz and a boost clock of 2505 MHz, and it is equipped with 16 GB of GDDR6X memory on a 256-bit bus, providing 716.8 GB/s of memory bandwidth.

In Microsoft Flight Simulator, the GPU's role becomes increasingly critical as resolution rises. The 4K Ultra setting yields 70 FPS, which is exactly half the 140 FPS equivalent frame rate at 1080p Ultra (117 FPS). This direct halving at the highest settings shows the GPU working at its full capacity. The 16 GB of VRAM is more than sufficient for the game's high-resolution textures, and the 716.8 GB/s bandwidth ensures that terrain data can be streamed without stuttering.

The RTX 4080's nearest rival, the RTX 4080 SUPER, scores within 0.1% in average benchmarks, confirming that this card is at the top of its performance tier. The 86th percentile ranking among all GPUs means it outperforms the vast majority of graphics cards in the database. The card's 48.74 TFLOPS of FP32 compute power provides ample headroom for the game's complex shader work, particularly at 4K where pixel throughput demands are highest.

The GPU's memory configuration is particularly well-suited to this game. The 256-bit bus and 716.8 GB/s bandwidth allow for rapid loading of the detailed scenery that defines Microsoft Flight Simulator. The 16 GB capacity ensures that even at Ultra settings with high-resolution textures, the card never runs out of memory, which is a common issue with lower-VRAM cards in this title.

Settings Recommendations

The measured FPS data provides clear guidance on which preset to choose for the best experience. At 4K, the Medium preset stands out as the optimal balance: it delivers 97 FPS average with a minimum of 83 FPS, ensuring smooth gameplay without dipping below 60 FPS. The High preset at 4K drops to 73 FPS, which is still playable but leaves less headroom for complex scenes. The Ultra preset at 4K is the most demanding, averaging 70 FPS, which is acceptable but may suffer in dense urban areas or heavy weather.

For 1440p users, the High preset is the best choice, offering 99 FPS average. This is a significant jump from the 73 FPS at 4K High, and it provides a smooth experience with high visual fidelity. The 1440p Medium preset offers 132 FPS, which is excellent for users with high-refresh-rate monitors, but the visual upgrade from Medium to High is worth the 33 FPS cost for most players. The 1440p Ultra preset at 95 FPS is also viable, though the difference between High and Ultra is minimal in this game.

At 1080p, the High preset at 123 FPS is the recommended starting point. The Medium preset at 164 FPS is ideal for competitive play or users with 144Hz monitors, but the Low preset at 187 FPS offers diminishing returns in visual quality. The 1080p Ultra preset at 117 FPS is the most visually impressive, but the 6 FPS advantage of High over Ultra is negligible, making High the better value for most users.

The data shows that the Medium preset provides the most consistent frame pacing across all resolutions, with the only complete minimum and maximum data points. At 4K Medium, the minimum of 83 FPS and maximum of 112 FPS indicate a tight frame time distribution, whereas the absence of min/max data for other presets suggests they may have more variability. For a stable and visually rich experience, the Medium preset at any resolution is the safest recommendation, with High being the choice for users who prioritize visual quality and can tolerate slightly lower frame rates.
