Microsoft Flight Simulator

Microsoft Flight Simulator is one of the most demanding titles in the benchmark database, and this pairing of the AMD Ryzen 7 9800X3D with the NVIDIA GeForce RTX 4070 shows a clear split between CPU-bound and GPU-bound behavior. The measured data reveals that this combo is highly capable at 1080p, but the experience becomes progressively more GPU-limited as resolution climbs. The Ryzen 7 9800X3D’s 3D V-Cache and Zen 5 architecture provide the raw single-threaded muscle the simulator craves, while the RTX 4070’s 12 GB of GDDR6X memory and Ada Lovelace architecture do the heavy lifting for pixel throughput. This is a balanced system for flight sim enthusiasts, but the numbers show you need to manage settings carefully to hit your target frame rate at higher resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K is stark and tells a clear story about where the bottleneck lies. At 1080p High settings, the combo produces 97.5 FPS, but that falls to 75.8 FPS at 1440p and further to 56 FPS at 4K. That is a 42% reduction in average frame rate when moving from 1080p to 4K, which indicates the GPU is becoming the limiting factor. The CPU is doing its job, but the RTX 4070’s pixel fill rate and memory bandwidth are being saturated as resolution increases.

The scaling pattern is consistent across all settings presets. At Low settings, the drop from 1080p to 4K is from 165.1 FPS down to 93.4 FPS, a 43% decline. At Ultra settings, the drop is from 92.7 FPS to 50.6 FPS, a 45% decline. This uniformity suggests that resolution scaling is dominated by the GPU’s rasterization and shading throughput, not by CPU-side physics or draw calls. The Ryzen 7 9800X3D has enough headroom to feed the GPU at all resolutions, but the RTX 4070 simply cannot maintain the same frame rates when pixel count quadruples.

Interestingly, the delta between Low and Ultra at the same resolution is smaller than the delta between resolutions at the same preset. At 1080p, Low gives 165.1 FPS while Ultra gives 92.7 FPS—a 56% uplift for Low. But at 4K, Low gives 93.4 FPS while Ultra gives 50.6 FPS—an 85% uplift for Low. This means the GPU is more sensitive to settings at 4K, and the CPU is rarely the constraint. The data suggests that for 4K play, you are always GPU-bound, and the only way to recover frame rates is to lower the preset.

How This Combo Ranks

This specific combination of components ranks 494th out of 1795 tested combos in Microsoft Flight Simulator. That places it in the top 27.5% of all systems in the database, which is a solid result for a single-GPU, single-CPU setup. The rank reflects the synergy between the Ryzen 7 9800X3D’s strong multi-threaded performance and the RTX 4070’s mid-range rasterization power.

The CPU itself sits in the 90th percentile against all processors, with an average benchmark score of 37780. Its nearest rivals are the Intel Xeon 6353P (score 37811, delta -0.1%), Intel Core Ultra 5 225 (score 37831, delta -0.1%), Intel Core i9-13900HK (score 38020, delta -0.6%), and Intel Core i5-13600KF (score 38028, delta -0.7%). The Ryzen 7 9800X3D is effectively tied with these competitors, being within 0.7% of all of them. This means the CPU is not the differentiator in this combo’s ranking; the GPU is more likely the limiting factor.

The GPU sits in the 81st percentile against all GPUs, with an average benchmark score of 37283. Its nearest rivals include the AMD Radeon RX Vega 56 (score 37507, delta -0.6%), NVIDIA GeForce MX570 A (score 38008, delta -1.9%), NVIDIA GeForce RTX 4080 Mobile (score 38135, delta -2.2%), and AMD Radeon RX 5300M (score 36371, delta +2.5%). The RTX 4070 is 2.2% behind the RTX 4080 Mobile and 2.5% ahead of the RX 5300M, which shows it is a solid mid-pack performer. The combo’s 494th rank out of 1795 reflects this balanced, slightly CPU-favored pairing.

GPU Role

The RTX 4070’s 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which is crucial for a game like Microsoft Flight Simulator that streams large terrain and texture data. The memory clock runs at 1313 MHz with 21 Gbps effective speed, and the GPU has a boost clock of 2475 MHz. These clocks, combined with 5888 shading units and 64 ROPs, give the card a pixel rate of 158.4 GPixel/s and a texture rate of 455.4 GTexel/s.

The data shows that the GPU’s role becomes more pronounced at higher resolutions. At 1080p, the CPU can push the RTX 4070 to 165.1 FPS on Low settings, but the GPU’s limits show at 4K Ultra, where it drops to 50.6 FPS. The FP32 performance of 29.15 TFLOPS is adequate for this title, but the 12 GB memory size may become a constraint at 4K with high-resolution texture packs, though the measured data does not show a hard VRAM limit. The GPU’s 81st percentile ranking against all GPUs, with an average score of 37283, confirms it is a competent but not top-tier part for this workload.

The RTX 4070’s TDP of 200 W and dual-slot design make it a practical choice for most builds, and its PCIe 4.0 x16 interface is sufficient. The card’s nearest rival, the RTX 4080 Mobile, is only 2.2% faster in synthetic benchmarks, but in actual game data, the desktop RTX 4070 holds its own. The GPU is clearly the component that dictates frame rates at 1440p and 4K, while the CPU has ample headroom.

Settings Recommendations

For the best experience per the measured rows, the Medium preset at 1440p appears to be the sweet spot. It delivers 99.5 FPS, which is above the 60 FPS threshold for smooth simulation, and the visual quality is noticeably better than Low. At 1080p, Medium gives 127.2 FPS, which is excellent for high-refresh monitors. If you prioritize frame rate over visuals, Low at 1080p offers 165.1 FPS, which is ideal for competitive or fast-paced flying.

At 4K, the data suggests you should stick to Medium or Low. Medium gives 73.6 FPS, which is playable, while High gives 56 FPS and Ultra drops to 50.6 FPS. The jump from Low to Medium at 4K is only 20 FPS (93.4 to 73.6), but the visual improvement is significant. If you have a 60 Hz 4K display, Medium is the recommended preset, as it maintains an average above 60 FPS. For 1440p, High at 75.8 FPS is acceptable, but Medium at 99.5 FPS provides more headroom for dips during complex scenes.

The data shows that Ultra settings are only viable at 1080p, where 92.7 FPS is still playable. At 1440p and 4K, Ultra drops below 71 FPS and 51 FPS respectively, which may cause stutters in dense urban or mountainous areas. The measured rows indicate that Medium is the most balanced preset across all resolutions, offering the best trade-off between visual fidelity and frame rate.

Measured FPS Breakdown

At 1920x1080, the combo produces 165.1 FPS on Low, 127.2 FPS on Medium, 97.5 FPS on High, and 92.7 FPS on Ultra. The gap between Low and Ultra is 72.4 FPS, which shows how much headroom the CPU provides at this resolution. The RTX 4070 is not the bottleneck here; the simulator’s single-threaded performance is well-served by the Ryzen 7 9800X3D.

At 2560x1440, the numbers drop to 132.6 FPS on Low, 99.5 FPS on Medium, 75.8 FPS on High, and 70.6 FPS on Ultra. The percentage drop from 1080p to 1440p ranges from 20% (Low) to 24% (High), indicating a mild GPU constraint. Medium remains above 90 FPS, making it the best choice for 1440p gaming.

At 3840x2160, the results are 93.4 FPS on Low, 73.6 FPS on Medium, 56 FPS on High, and 50.6 FPS on Ultra. The drop from 1080p is severe, with Low falling 43% and Ultra falling 45%. This is where the GPU’s 504.2 GB/s bandwidth and 12 GB memory are stressed. The RTX 4070’s pixel rate of 158.4 GPixel/s is simply not enough for 4K Ultra in this title. High at 56 FPS is borderline, but Medium at 73.6 FPS is the recommended setting for 4K.
