CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7700X is an 8-core, 16-thread processor built on the TSMC 5 nm process with a base clock of 4.50 GHz and a boost clock of 5.40 GHz. It features 32 MB of shared L3 cache and 1 MB of L2 cache per core, with a 64 KB L1 allocation per core. This CPU sits in the 89th percentile against all tested processors, with an average benchmark score of 34,313.

In synthetic workloads, the 7700X shows strong scaling from 2 threads to 16 threads. Its 3DMark scores climb from 2,112 at 2 threads to 7,057 at 8 threads, reaching 8,859 at 16 threads. The Cinebench R23 multicore result of 30,325 confirms that all 8 physical cores are effectively utilized. Single-thread performance is equally robust, with a Cinebench R23 single-core score of 4,281 and a Geekbench single-core result of 2,985.

For Microsoft Flight Simulator, the CPU's role is substantial. This flight simulator relies heavily on draw-call processing, terrain streaming, and complex autogen logic, all of which stress single-thread performance and memory latency. The 7700X's high boost clock of 5.40 GHz and its Zen 4 architecture (Raphael) provide the fast single-core throughput needed for the game's main simulation thread. Meanwhile, the 8 cores handle secondary tasks like weather simulation and AI traffic processing.

Comparing to its nearest rivals, the 7700X is effectively tied with the Intel Core i5-13500, being just 0.4% ahead in average score. It trails the Intel Core Ultra 7 165H by 0.8% and the AMD EPYC 4244P by 0.8%. The benchmark data indicates that the 7700X does not bottleneck this game at lower resolutions, as evidenced by the FPS scaling patterns discussed later.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 uses the GA104 chip on Samsung's 8 nm process, with a base clock of 1500 MHz and a boost clock of 1725 MHz. Memory is 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The GPU has 5,888 shading units, 184 texture mapping units, 96 ROPs, 46 ray tracing cores, and 184 tensor cores, producing 20.31 TFLOPS of FP32 compute.

The RTX 3070 sits in the 72nd percentile of all GPUs, with an average benchmark score of 28,238. Its performance is closely matched with the AMD Radeon RX 6600 XT, where the RTX 3070 is 0.9% ahead. Against the AMD FirePro S7150, it trails by 0.6%, and it is 1% ahead of the NVIDIA GeForce GTX 980 Ti, with the AMD Radeon R9 M295X 1.1% behind.

In Microsoft Flight Simulator, the GPU's 8 GB VRAM capacity is a significant limiting factor at higher settings. The game's high-resolution terrain textures and detailed aircraft models consume memory quickly. At 4K resolution with Ultra settings, the data shows the average FPS drops to 42.2, suggesting the GPU is under heavy memory pressure. The 448.0 GB/s memory bandwidth is adequate for 1080p and 1440p, but at 4K, the combination of memory capacity and bandwidth becomes the primary constraint.

The RTX 3070's 1725 MHz boost clock allows for consistent frame delivery in less demanding scenes, but the measured FPS data reveals that settings scaling has a stronger effect than resolution scaling, indicating the GPU's compute resources are the bottleneck rather than the CPU.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 7 7700X and NVIDIA GeForce RTX 3070 ranks 826th out of 1,795 tested combos in Microsoft Flight Simulator. This places it in the middle of the field, which is notable given the CPU's high percentile standing (89th) and the GPU's more moderate standing (72nd).

The rank of 826 out of 1,795 suggests that while the CPU is a top-tier performer, the GPU holds this combo back from the upper echelons. Many combos ranked above this pairing likely feature higher-end GPUs paired with similar or lesser CPUs. The data indicates that in this simulator, the GPU is the performance limiter, as the CPU's strong single-thread scores do not translate into top-tier overall rankings when paired with a mid-range GPU like the RTX 3070.

This mid-pack ranking is consistent with the GPU's percentile of 72. The combo's position relative to its 1,795 total combinations implies that roughly 54% of tested combos outperform it, which aligns with the expectation that faster GPUs dominate in a graphics-intensive title like Microsoft Flight Simulator.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the RTX 3070 and 7700X deliver an average of 132.4 FPS on Low settings. This drops to 103.9 FPS on Medium, 76.7 FPS on High, and 75.0 FPS on Ultra. The gap between High and Ultra is minimal at just 1.7 FPS, indicating that Ultra settings add visual fidelity without a significant frame rate penalty at this resolution.

Moving to 2560x1440, the averages are 105.9 FPS on Low, 83.9 FPS on Medium, 66.1 FPS on High, and 63.0 FPS on Ultra. The drop from 1080p to 1440p at Low settings is 26.5 FPS, while at Ultra settings the drop is 12.0 FPS. This suggests that at higher settings, the GPU is already working hard at 1080p, so the resolution increase has a smaller relative impact.

At 3840x2160, the RTX 3070 manages 81.1 FPS on Low, 61.4 FPS on Medium, 45.5 FPS on High, and 42.2 FPS on Ultra. The 4K Low result is still playable, but the High and Ultra settings fall below the 60 FPS threshold, indicating that this GPU cannot maintain smooth frame rates at 4K with higher quality presets.

The data shows a consistent pattern: at every resolution, the difference between High and Ultra is small (1.7 FPS at 1080p, 3.1 FPS at 1440p, 3.3 FPS at 4K), while the difference between Low and Medium is larger (28.5 FPS at 1080p, 22.0 FPS at 1440p, 19.7 FPS at 4K). This suggests that the Medium setting captures most of the visual improvements without the heavy performance cost of Ultra.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the FPS scaling from 1080p to 4K reveals which component is the primary bottleneck. At Low settings, the average FPS drops from 132.4 at 1080p to 105.9 at 1440p (a 20.0% reduction) and then to 81.1 at 4K (an additional 23.4% reduction from 1440p). This steep decline indicates that even at Low settings, the GPU is becoming the limiting factor as resolution increases.

At Medium settings, the scaling shows 103.9 FPS at 1080p, 83.9 FPS at 1440p, and 61.4 FPS at 4K. The percentage drop from 1080p to 1440p is 19.2%, and from 1440p to 4K is 26.8%. The accelerating decline at higher resolutions confirms that the GPU's memory bandwidth and compute resources are being saturated.

For High settings, the numbers are 76.7 FPS at 1080p, 66.1 FPS at 1440p, and 45.5 FPS at 4K. The drop from 1080p to 1440p is 13.8%, which is smaller than the drop from 1440p to 4K at 31.2%. This pattern becomes even more pronounced at Ultra settings: 75.0 FPS at 1080p, 63.0 FPS at 1440p (a 16.0% drop), and 42.2 FPS at 4K (a 33.0% drop from 1440p).

The data strongly indicates that the GPU is the limiting component in this pairing. If the CPU were the bottleneck, we would expect to see similar FPS values across resolutions at a given setting, or at least a plateau at higher resolutions. Instead, the FPS continues to fall significantly at each resolution step, particularly at 4K where the RTX 3070's 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for the game's demands.

The CPU's strong single-thread performance (4,281 in Cinebench R23 single-core) ensures that at 1080p, the system can reach 132.4 FPS on Low settings, which is well above what the GPU can sustain at higher resolutions. The fact that the 1080p Ultra result (75.0 FPS) is close to the 1440p High result (66.1 FPS) further illustrates that the GPU's capabilities diminish quickly with increased resolution and quality demands. In summary, this combo is CPU-balanced at 1080p Low, but becomes heavily GPU-bound as resolution and settings increase, with the RTX 3070 unable to maintain 60 FPS at 4K beyond Medium settings.
