# Microsoft Flight Simulator: AMD Ryzen 7 5700 + NVIDIA GeForce RTX 5080

The pairing of AMD's Ryzen 7 5700 with NVIDIA's RTX 5080 produces a simulation platform that scales predictably across resolutions, with the CPU emerging as the primary constraint at lower settings. Measured frame rates show the combo reaching 174.8 FPS at 1080p Low, yet dropping to 72.3 FPS at 4K Ultra, revealing a system that favors high-refresh 1440p play over maximum 4K fidelity. The data indicates a balanced but CPU-limited configuration in this flight simulator, where the Ryzen 7 5700's Zen 3 architecture handles the simulation's heavy single-thread load admirably, while the RTX 5080's Blackwell GPU provides ample headroom for graphical scaling.

Resolution Scaling

The frame rate trajectory across resolutions tells a clear story about where the bottleneck resides. From 1080p to 1440p, the average FPS at High settings drops from 133.0 to 103.6, a 22.1% reduction. Moving from 1440p to 4K at High settings, the average falls further to 75.0 FPS, a 27.6% decrease from the 1440p figure. This progressive decline is consistent with a GPU-bound scenario at higher resolutions, but the pattern at Low settings reveals the CPU's influence more starkly.

At Low settings, the combo produces 174.8 FPS at 1080p, 159.4 FPS at 1440p, and 130.0 FPS at 4K. The relatively modest drop between 1080p and 1440p (8.8%) suggests the CPU is limiting performance at these lower graphical loads. The Ryzen 7 5700, with its 8 cores and 16 threads, delivers strong single-thread performance — evidenced by its 3DMark single-thread score of 901 — but the simulation's engine appears to cap frame generation once the GPU is no longer the limiting factor. At 4K Low, the 130.0 FPS result shows the GPU still has headroom, but the CPU prevents higher frame rates.

The Ultra settings curve reinforces this interpretation. At 1080p Ultra, the combo hits 125.4 FPS; at 1440p Ultra, 100.0 FPS; and at 4K Ultra, 72.3 FPS. The 1080p-to-1440p drop of 20.3% is nearly identical to the High settings drop, while the 1440p-to-4K drop of 27.7% mirrors the High settings trend. This consistency suggests that at Ultra settings, the GPU begins to take over as the primary constraint, with the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth handling the increased texture and geometry loads efficiently.

The most telling data point is the Low settings spread: 174.8 FPS at 1080p versus 130.0 FPS at 4K. This 25.6% reduction at Low settings — where GPU load is minimal — indicates the CPU's performance ceiling sits around 175 FPS, and the simulation's engine cannot push beyond this regardless of resolution. This is a classic CPU-bound signature, where the Ryzen 7 5700's 3.70 GHz base and 4.60 GHz boost clocks define the upper limit.

How This Combo Ranks

The AMD Ryzen 7 5700 and NVIDIA GeForce RTX 5080 combination achieves a rank of 90 out of 1,795 tested combos in Microsoft Flight Simulator. This top-5% placement reflects the strength of both components working in concert. The CPU's position in the 84th percentile of all CPUs, combined with the GPU's 89th percentile standing, creates a system that outperforms the vast majority of alternatives.

The Ryzen 7 5700's nearest rivals include the Intel Core i9-9900K (average score 27,043, delta 0.7%), the Intel Core i7-12700H (27,006, delta 0.8%), and the Intel Core i7-1370P (26,991, delta 0.8%). These sub-1% deltas indicate the CPU is competitively matched with several high-end processors, but its 8-core/16-thread configuration and Zen 3 architecture provide enough computational headroom to avoid becoming a severe bottleneck in this flight simulator.

On the GPU side, the RTX 5080's nearest rivals include the Intel Arc A570M (58,239 average score, delta 1.6%), the Intel Arc Pro A60 (60,326, delta -1.9%), and the Intel Arc A580 (57,756, delta 2.5%). The RTX 5080's average benchmark score of 59,188 places it ahead of most competitors, with the negative delta for the Arc Pro A60 indicating the RTX 5080 outperforms that card by 1.9%.

The combo's rank of 90 suggests that while individual components are strong, the pairing is not optimal for every game. In Microsoft Flight Simulator specifically, the CPU's single-thread performance — reflected in its 3DMark single-thread score of 901 and Cinebench R23 single-core score of 2,916 — is sufficient to feed the RTX 5080 adequately at most settings, but the simulation's engine does not fully utilize the GPU's capabilities at lower resolutions.

Measured FPS Breakdown

The measured frame rates provide a comprehensive picture of performance across three resolutions and four settings levels.

1080p (1920x1080): The combo delivers its highest frame rates at this resolution. At Low settings, the average FPS reaches 174.8. Medium settings produce 157.5 FPS, High settings yield 133.0 FPS, and Ultra settings drop to 125.4 FPS. The spread between Low and Ultra is 49.4 FPS, representing a 28.3% reduction from the Low setting's peak.

1440p (2560x1440): Performance remains strong at this resolution. Low settings achieve 159.4 FPS, Medium settings reach 139.6 FPS, High settings produce 103.6 FPS, and Ultra settings deliver exactly 100.0 FPS. The gap between Low and Ultra is 59.4 FPS, a 37.3% reduction.

4K (3840x2160): The highest resolution shows more significant performance scaling. Low settings produce 130.0 FPS, Medium settings reach 103.7 FPS, High settings deliver 75.0 FPS, and Ultra settings bottom out at 72.3 FPS. The difference between Low and Ultra at 4K is 57.7 FPS, a 44.4% reduction.

The data reveals that Medium settings offer the most consistent performance across resolutions, with only a 34.2% drop from 1080p (157.5 FPS) to 4K (103.7 FPS). High settings show a 43.6% drop from 1080p to 4K, while Low settings exhibit a 25.6% drop. Ultra settings have the steepest decline at 42.3%, but the 4K Ultra result of 72.3 FPS remains playable.

GPU Role

The NVIDIA GeForce RTX 5080 plays a critical role in this combo's performance, particularly at higher resolutions and settings. The GPU features 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its base clock runs at 2,295 MHz with a boost clock of 2,617 MHz, and the card is built on TSMC's 5 nm process with 45,600 million transistors.

In Microsoft Flight Simulator, the GPU's memory capacity and bandwidth become decisive factors at 4K Ultra settings, where the combo produces 72.3 FPS. The 16 GB frame buffer allows for high-resolution textures without swapping, while the 960.0 GB/s bandwidth ensures smooth streaming of terrain and aircraft data. The GPU's 89th percentile ranking among all GPUs, with an average benchmark score of 59,188, confirms its high-end positioning.

The RTX 5080's shading units (10,752), texture mapping units (336), and render output units (112) contribute to its 56.28 TFLOPS of FP32 performance. This computational power is evident in the 4K Medium result of 103.7 FPS, which demonstrates the GPU's ability to handle moderately demanding graphical loads without CPU interference.

However, the data also shows the GPU is not fully utilized at lower settings. At 1080p Low, the combo produces 174.8 FPS, but the RTX 5080's capability suggests it could push higher if not for the CPU's limitation. The Ryzen 7 5700's 65 W TDP and 16 MB of L3 cache provide solid single-thread performance, but the simulation's engine appears to cap frame generation around 175 FPS. This is corroborated by the relatively small delta between 1080p Low (174.8 FPS) and 1440p Low (159.4 FPS), which indicates GPU headroom is being left on the table.

At higher settings, the GPU's role expands significantly. The transition from Medium to Ultra at 4K results in a 30.2% performance drop (103.7 to 72.3 FPS), reflecting the increased load on the RTX 5080's memory subsystem and compute units. The GPU's 84 RT cores and 336 tensor cores also support the simulation's advanced lighting and AI features, though their specific impact is not isolated in the measured data.
