Microsoft Flight Simulator

How This Combo Ranks

The AMD Ryzen 5 5600 paired with the NVIDIA GeForce RTX 4080 ranks 324th out of 3714 tested combos in Microsoft Flight Simulator, placing it in the top 8.7% of all configurations evaluated. This is a strong showing, but the ranking reveals more about the balance of this pairing than raw performance. The combo sits in the 91st percentile of tested systems, which is impressive given that the CPU itself only ranks in the 74th percentile among all processors. The GPU, by contrast, ranks in the 86th percentile among all graphics cards. This gap—where the GPU outperforms the CPU in their respective percentile standings—is the defining characteristic of this build: the RTX 4080 is doing the heavy lifting, while the Ryzen 5 5600 provides sufficient but not exceptional support.

In practical terms, this rank places the combo well above the median tested configuration. The delta between the CPU's percentile (74th) and the combo's overall rank percentile (91st) suggests that Microsoft Flight Simulator is scaling heavily with GPU capability in this pairing. The CPU's nearest rivals—the Intel Core Ultra 7 258V and AMD Ryzen 5 8500G, both within 0.2% of its average benchmark score—indicate that the 5600 is holding its own against newer, more expensive processors, but it is not a class leader. The RTX 4080's nearest rival, the RTX 4080 SUPER, is just 0.1% ahead in average score, meaning this GPU is essentially at the top of its performance tier. The combination of a mid-tier CPU with a near-top-tier GPU creates a system that excels in GPU-bound scenarios but may leave performance on the table in CPU-limited situations.

CPU Role

The AMD Ryzen 5 5600 brings 6 cores and 12 threads to the pairing, built on the Zen 3 architecture (codenamed Vermeer) using TSMC's 7nm process. Its base clock runs at 3.50 GHz with a boost clock up to 4.40 GHz, and it carries 32 MB of shared L3 cache. In synthetic benchmarks, the CPU demonstrates a clear strength in multithreaded workloads: its Cinebench R23 multicore score of 18,309 points is roughly 7.1 times its single-core score of 2,584 points. The 3DMark results show a similar pattern, with the 16-thread score (5,641) nearly matching the max-thread score (5,659), indicating that the processor scales well up to its full thread count but gains almost nothing beyond 16 threads. This is typical for a 6-core/12-thread part—it saturates quickly but handles its available threads efficiently.

For Microsoft Flight Simulator specifically, the CPU's role is to feed the simulation's physics and AI systems. The game is known for heavy single-thread demands, and here the 5600's single-thread performance is respectable but not elite. Its Geekbench single-core score of 1,936 and PassMark single-thread score of 3,256 place it in the upper-middle tier. The PassMark physics score of 1,285 is notably lower than the multithread score of 21,541, suggesting that the CPU's raw physics compute capability is modest relative to its overall throughput. In this game, that means the CPU can become a bottleneck at lower resolutions where the GPU has excess headroom, but at higher resolutions the GPU takes over as the primary driver.

The CPU's 65W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for this workload, though not exceptional. Its 7nm process and 4,150 million transistors on a 74 mm² die indicate a power-efficient design that won't thermally throttle in most systems. The unlocked multiplier allows overclocking, which could narrow the gap to the CPU's nearest rivals, but even at stock settings the 5600 provides enough compute to keep the RTX 4080 reasonably fed in this simulation title.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and its specifications confirm why. Built on the Ada Lovelace architecture using TSMC's 5nm process, the GPU packs 45,900 million transistors on a 379 mm² die. It features 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth—a figure that becomes critical at high resolutions and Ultra settings. The memory runs at 1400 MHz (22.4 Gbps effective), and the GPU clock boosts to 2505 MHz. With 9,728 shading units, 304 TMUs, and 112 ROPs, the RTX 4080 is a throughput monster, capable of 48.74 TFLOPS of FP32 compute.

In Microsoft Flight Simulator, the GPU's role is to render vast landscapes, detailed aircraft models, and complex lighting. The 16 GB VRAM is a significant asset here—the game's high-resolution textures and photogrammetry data can consume large amounts of memory, and 16 GB ensures the GPU won't spill into system RAM even at 4K Ultra. The 76 RT cores handle ray-traced effects, though the game's use of RT is selective. The 304 tensor cores provide DLSS support, which can boost frame rates substantially, though the measured FPS data does not specify whether DLSS was enabled.

The GPU's benchmark results reinforce its top-tier status. Its PassMark G3D score of 34,457 and Geekbench Vulkan score of 263,779 are strong, but the 3DMark Steel Nomad DX12 score of 6,567 is the most relevant for modern gaming. The GPU sits in the 86th percentile among all graphics cards, with its nearest rival (RTX 4080 SUPER) just 0.1% ahead—essentially a statistical tie. This means the RTX 4080 is performing at the very edge of its class, and any performance differences in-game are more likely attributable to the CPU or system configuration than the GPU itself.

Measured FPS Breakdown

The measured FPS data shows a consistent pattern across all resolutions: the RTX 4080 delivers playable frame rates even at 4K Ultra, and the system scales well when settings are reduced. At 1920x1080, the combo achieves an average of 117 FPS on Ultra settings, rising to 123 FPS on High, 157 FPS on Medium, and peaking at 172 FPS on Low. The Medium setting shows the tightest frame time distribution with a minimum of 134 FPS and maximum of 181 FPS, indicating consistent performance. The gap between Ultra and Low at 1080p is 55 FPS (172 vs 117), which is substantial but expected given the visual fidelity difference.

Moving to 2560x1440, the averages drop but remain strong: 95 FPS on Ultra, 99 FPS on High, 132 FPS on Medium, and 160 FPS on Low. The Medium settings at 1440p show a min/max range of 112 to 152 FPS, which is a 40 FPS spread—slightly wider than at 1080p, suggesting some frame pacing variance at higher resolution. The drop from 1080p Ultra to 1440p Ultra is 22 FPS (117 to 95), a 19% reduction that indicates the GPU is still handling the extra pixels comfortably.

At 3840x2160 (4K), the system remains viable: 70 FPS on Ultra, 73 FPS on High, 97 FPS on Medium, and 125 FPS on Low. The Medium setting at 4K shows a min/max of 83 to 112 FPS, which is a 29 FPS spread—the widest of any resolution/setting combination, indicating the GPU is working harder and frame times are less consistent. The 4K Ultra average of 70 FPS is right at the edge of what many consider "smooth" for a flight simulator, where the camera moves slowly and 60 FPS is often sufficient. The 4K Low setting at 125 FPS demonstrates that the RTX 4080 has enormous headroom when graphical load is reduced.

Resolution Scaling

The scaling from 1080p to 4K reveals the limiting component in this pairing. At Ultra settings, the FPS drops from 117 at 1080p to 95 at 1440p (a 19% reduction) and then to 70 at 4K (a further 26% reduction from 1440p). This steepening decline as resolution increases is the classic signature of a GPU-bound system—the RTX 4080 is the primary constraint at higher resolutions. At Low settings, the pattern is different: 172 FPS at 1080p drops to 160 at 1440p (only a 7% reduction) and then to 125 at 4K (a 22% reduction from 1440p). The relatively small drop from 1080p to 1440p at Low settings, followed by a larger drop to 4K, suggests that at Low settings the CPU is partially limiting performance at 1080p and 1440p, while the GPU becomes the clear bottleneck only at 4K.

The Medium settings provide the most revealing data. At 1080p Medium, the system averages 157 FPS; at 1440p Medium, it drops to 132 FPS (a 16% reduction); and at 4K Medium, it falls to 97 FPS (a 27% reduction from 1440p). The consistent ~16-27% reductions per resolution step indicate a balanced workload where both CPU and GPU contribute, but the GPU's load increases disproportionately with pixel count. The fact that 4K Medium (97 FPS) outperforms 1080p Ultra (117 FPS) by a significant margin suggests that the visual settings have a larger impact on performance than resolution alone—a useful data point for users who want to maximize image quality without sacrificing frame rate.

The limiting component analysis points to the CPU at lower resolutions and the GPU at 4K. At 1080p, the gap between Low (172 FPS) and Ultra (117 FPS) is 55 FPS, and the system cannot exceed 172 FPS even at Low—a ceiling that is likely imposed by the Ryzen 5 5600's single-thread performance. At 4K, the gap between Low (125 FPS) and Ultra (70 FPS) is also 55 FPS, but the absolute numbers are lower, confirming the GPU is the constraint. Users targeting high refresh rates at 1080p or 1440p will find the CPU limiting; those targeting 4K will find the GPU the primary factor.

FAQ

Q: Is this combo suitable for 4K gaming in Microsoft Flight Simulator?

A: Yes, the measured data shows an average of 70 FPS at 4K Ultra settings and 73 FPS at 4K High, both above the 60 FPS threshold commonly considered smooth for this genre. At 4K Medium, the average rises to 97 FPS, providing a comfortable margin.

Q: Which component is the bottleneck at 1080p?

A: At 1080p, the CPU is the limiting factor. The system reaches 172 FPS at Low settings but only 117 FPS at Ultra, and the relatively flat scaling from Low to Ultra at lower resolutions indicates the Ryzen 5 5600 cannot feed the RTX 4080 fast enough to reach higher frame rates.

Q: How does the CPU compare to its nearest rivals?

A: The Ryzen 5 5600's average benchmark score of 20,468 is within 0.5% of its nearest rivals—the Intel Core Ultra 7 258V (20,454, 0.1% slower), AMD Ryzen 5 8500G (20,425, 0.2% slower), AMD EPYC 9454P (20,422, 0.2% slower), and AMD EPYC 7713 (20,363, 0.5% slower). This means the 5600 is essentially performance-equivalent to these newer parts in synthetic tests.

Q: What is the best settings/resolution combination for smooth gameplay?

A: For a consistent 60+ FPS experience, 4K Medium (97 FPS average) or 1440p Ultra (95 FPS average) both work well. For higher refresh rates, 1080p Ultra at 117 FPS or 1440p High at 99 FPS are viable. The Medium settings at any resolution provide the most stable frame times, with the 1080p Medium showing a 134-181 FPS range.

Q: How much VRAM does the RTX 4080 have and is it enough?

A: The RTX 4080 has 16 GB of GDDR6X memory on a 256-bit bus with 716.8 GB/s bandwidth. This is sufficient for Microsoft Flight Simulator's high-resolution textures, and the measured FPS data shows no evidence of memory-related performance drops even at 4K Ultra settings.
