Resolution Scaling

The performance scaling from 1080p to 4K reveals a system that becomes progressively GPU-bound at higher resolutions, though the CPU remains a significant factor at 1080p. At Ultra settings, the average frame rate drops from 90.7 FPS at 1920x1080 to 69.7 FPS at 2560x1440, a decline of roughly 23%, and then further to 49.3 FPS at 3840x2160, representing an additional 29% drop. This steep decline indicates that the NVIDIA GeForce RTX 3080's rendering load is the primary constraint as pixel count rises, with the 10 GB GDDR6X memory buffer and 760.3 GB/s bandwidth being taxed heavily by the simulator's detailed scenery at 4K.

However, the scaling pattern at lower settings tells a different story. At Low settings, the frame rate only falls from 157.8 FPS at 1080p to 125.1 FPS at 1440p (a 21% reduction) and then to 91.1 FPS at 4K (a 27% further drop). The fact that 1080p Low produces nearly 158 FPS suggests the CPU can feed the GPU adequately when graphical load is minimal, but the diminishing returns between 1440p and 4K at all settings point to the GPU becoming the bottleneck. The gap between Low and Ultra at 1080p is 67.1 FPS (from 157.8 down to 90.7), while at 4K the same settings gap narrows to just 41.8 FPS (from 91.1 down to 49.3). This compression of performance ranges at higher resolutions confirms that the RTX 3080's compute and memory subsystems are the limiting factor at 4K, whereas at 1080p the AMD Ryzen 5 5600GT's six cores and twelve threads have more headroom to influence results.

CPU Role

The AMD Ryzen 5 5600GT, with its 6 cores, 12 threads, and boost clock of 4.60 GHz, demonstrates that a mid-range Zen 3 processor can sustain high frame rates in Microsoft Flight Simulator, but its influence wanes as resolution increases. At 1080p Low, the system achieves 157.8 FPS, which is likely near the CPU's practical ceiling for this title given its single-thread performance (3dmark_single_thread score of 913 and cinebench_r23_singlecore of 2438). The processor's 16 MB L3 cache and 51.2 GB/s memory bandwidth are adequate for feeding the RTX 3080 at this resolution, but the data shows that pushing to Ultra at 1080p drops performance to 90.7 FPS, suggesting that the CPU's thread scheduling becomes more involved with higher draw calls and physics calculations.

The CPU's multi-threaded capabilities, reflected in a cinebench_r23_multicore score of 17272 and a passmark_multithread score of 20325, place it in the 78th percentile among all CPUs. Its nearest rivals include the Intel Core i7-10700 (avgScore 20746) and AMD Ryzen 5 5600X (avgScore 20680), with deltaPct values of 0 and 0.3 respectively, indicating the 5600GT is essentially performance-equivalent to these chips in synthetic benchmarks. In gaming terms, this means the CPU is rarely the sole bottleneck at 1440p or 4K, where the GPU's workload dominates. At 1440p High, the system produces 73.1 FPS, and at 4K High it drops to 56.2 FPS, showing a predictable GPU-limited curve. The 65W TDP and 7nm TSMC process node suggest efficient power delivery, but the data does not indicate any thermal throttling that would alter these results.

How This Combo Ranks

The combination of AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 3080 achieves a rank of 545 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 70th percentile of all configurations. This ranking is respectable given that the CPU is a budget-oriented 5000-series part, but the GPU is a high-end Ampere card. The data suggests that the RTX 3080's 80th percentile GPU score (35787 average) is doing most of the heavy lifting, while the CPU's 78th percentile score (20740 average) is adequate but not exceptional. In practical terms, this combo outperforms roughly 70% of all tested systems in this flight simulator, which is notable for a CPU that launched at a $140 MSRP.

When compared to other combinations, the CPU's nearest rivals (Intel Core i7-10700, Intel Core i5-12490F, AMD Ryzen 5 5600X) all have similar average scores within 0.3% of the 5600GT, meaning that swapping to any of these CPUs would likely yield near-identical frame rates. The GPU's nearest rivals (AMD Radeon Pro Duo, AMD Radeon 880M, AMD Radeon RX 7900 GRE) are also within 1% of the RTX 3080's score, so the overall ranking is more dependent on the combination's synergy than on any single component's outlier performance.

Settings Recommendations

For the best experience, the data indicates that 2560x1440 with High settings is the sweet spot, delivering 73.1 FPS average. This resolution provides a significant visual upgrade over 1080p while maintaining frame rates well above 60 FPS. At 4K, High settings produce 56.2 FPS, which is playable but not ideal for a smooth experience; Medium settings at 4K yield 70.2 FPS, which is a better trade-off if the user insists on 4K. At 1080p, High settings offer 93.6 FPS, which is excellent for high-refresh-rate monitors, while Ultra at 1080p drops to 90.7 FPS, suggesting that the extra visual fidelity costs very little performance at this resolution. For users prioritizing frame rate over visuals, 1080p Low achieves 157.8 FPS, but this setting likely sacrifices too much scenery detail for a flight simulator.

The measured rows show that Medium settings at 1440p (96.5 FPS) provide a large performance buffer over High (73.1 FPS) with only modest visual degradation, making it a strong recommendation for users with 144Hz displays. At 4K, Ultra settings drop to 49.3 FPS, which is below the 60 FPS threshold and would likely result in noticeable stutter; Medium at 4K (70.2 FPS) is the highest preset that maintains smooth performance at this resolution.

Measured FPS Breakdown

At 1920x1080, the system delivers 157.8 FPS on Low, 121.7 FPS on Medium, 93.6 FPS on High, and 90.7 FPS on Ultra. The jump from Low to Medium costs 36.1 FPS, while the jump from Medium to High costs 28.1 FPS, and High to Ultra costs only 2.9 FPS, indicating diminishing returns at the highest preset. At 2560x1440, performance drops to 125.1 FPS on Low, 96.5 FPS on Medium, 73.1 FPS on High, and 69.7 FPS on Ultra. The relative scaling is similar, with Low to Medium costing 28.6 FPS, Medium to High costing 23.4 FPS, and High to Ultra costing only 3.4 FPS.

At 3840x2160, the frame rates are 91.1 FPS on Low, 70.2 FPS on Medium, 56.2 FPS on High, and 49.3 FPS on Ultra. The performance gaps narrow further: Low to Medium costs 20.9 FPS, Medium to High costs 14.0 FPS, and High to Ultra costs 6.9 FPS. This pattern shows that as resolution increases, the absolute FPS differences between settings shrink, but the percentage cost of each setting tier remains relatively consistent. The 4K Ultra result of 49.3 FPS is the only measured point below 50 FPS, confirming that this setting is too demanding for consistent smoothness.

GPU Role

The NVIDIA GeForce RTX 3080, based on the GA102 chip with Ampere architecture, plays the dominant role in this system's gaming performance. Its 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth, which is crucial for Microsoft Flight Simulator's streaming of high-resolution terrain textures. The GPU's 8704 shading units, 272 TMUs, and 96 ROPs enable a pixel rate of 164.2 GPixel/s and a texture rate of 465.1 GTexel/s, giving it the raw compute power to handle complex lighting and shadow effects at high settings. The boost clock of 1710 MHz and base clock of 1440 MHz are modest for a high-end card, but the FP32 performance of 29.77 TFLOPS ensures that the GPU is rarely the bottleneck in synthetic benchmarks.

In the measured FPS data, the GPU's role is evident in the scaling from 1080p to 4K. At Ultra settings, the performance drops from 90.7 FPS to 69.7 FPS to 49.3 FPS as resolution increases, which is a typical GPU-bound curve. The GPU's 80th percentile ranking (avgScore 35787) places it just ahead of the AMD Radeon RX 7900 GRE (avgScore 36101, deltaPct -0.9) and behind the AMD Radeon Pro Duo (avgScore 35860, deltaPct -0.2). The RTX 3080's DirectX 12 passmark score of 100 is notably lower than its DirectX 11 score of 207, which may indicate driver overhead in certain workloads, but this does not appear to hinder the game-specific results where 4K High still achieves 56.2 FPS. The GPU's 320W TDP and suggested 700W PSU indicate high power draw, but the data shows no thermal-related performance degradation in the measured FPS figures.
