Microsoft Flight Simulator

The Intel Core i7-14700KF paired with the AMD Radeon RX 6600 presents a distinct performance profile in Microsoft Flight Simulator, a title known for its demanding rendering of terrain and aircraft systems. The benchmark data reveals a configuration where the CPU’s substantial compute resources are frequently held in check by the GPU’s memory and throughput limits, particularly as resolution scales upward. This analysis breaks down the measured FPS across the tested settings to clarify where the bottleneck lies and how this combination ranks against the broader field of tested hardware.

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

The Core i7-14700KF is a 20-core, 28-thread processor built on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 33 MB L3 cache. In synthetic benchmarks, the chip demonstrates strong single-threaded and multi-threaded capability, achieving a Cinebench R23 single-core score of 6290 and a multi-core score of 44557. This positions the CPU in the 96th percentile against all processors, indicating top-tier compute performance.

In Microsoft Flight Simulator, the CPU handles the simulation logic, including flight dynamics and scenery generation. The data shows that at 1080p with Low settings, the system achieves 93 FPS, which is the highest frame rate recorded across all configurations. This suggests that at lower resolutions and reduced graphical loads, the CPU’s high boost clock and substantial core count are sufficient to feed the GPU efficiently. However, the performance scaling from Low to Ultra settings at 1080p shows a drop from 93 FPS to 53.8 FPS, a 42% reduction. This decline is more attributable to the GPU’s rendering workload than to CPU limitations, as the processor’s single-core score of 6290 in Cinebench R23 indicates it can handle the game’s primary thread demands without becoming the primary constraint.

The processor’s nearest rivals, such as the Intel Core i7-14700K (average score 70074) and the AMD Ryzen 9 9950X (average score 70420), show a deltaPct of 0% and -0.4% respectively, meaning the 14700KF’s average benchmark score of 70104 is statistically on par with these chips. In game, this means the CPU is unlikely to be the differentiating factor when comparing to other high-end processors; the variance in FPS across settings will be driven by the GPU.

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

The AMD Radeon RX 6600 is an RDNA 2.0 architecture GPU with 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 224.0 GB/s. Its boost clock is rated at 2491 MHz, with a game clock of 2044 MHz. The GPU’s compute capabilities include 1792 shading units, 112 TMUs, and 64 ROPs, delivering a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s. The card’s percentile rank is 69th among all GPUs, and its average benchmark score of 25235 places it near the AMD Radeon 890M (deltaPct 0%) and the NVIDIA GeForce RTX 3060 Ti (deltaPct 0.5%).

In Flight Simulator, the GPU’s role is to render the complex scenery, including photorealistic terrain, weather effects, and aircraft models. The 8 GB VRAM capacity is a notable factor here; at 4K resolution with Ultra settings, the measured average FPS is 28.6, which is below the threshold for smooth playability. The drop from 4K Low (55.9 FPS) to 4K Ultra (28.6 FPS) represents a 49% reduction, indicating that the GPU is heavily stressed by the increased texture and shader complexity. The memory bandwidth of 224.0 GB/s becomes a limiting factor at higher resolutions, as the GPU must stream more data per frame, and the 128-bit bus width restricts throughput relative to wider-memory GPUs.

The GPU’s boost clock of 2491 MHz provides decent raw compute, but the 8 GB frame buffer is insufficient for the highest quality presets at 4K, where average FPS falls to 28.6. At 1440p, the Ultra setting yields 38.5 FPS, which is playable but not ideal, while the High setting at 1440p produces 42.6 FPS. The data shows that the GPU is the primary bottleneck in most scenarios, especially when settings are increased beyond Low, as the CPU’s performance headroom is not fully utilized.

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

The measured FPS across resolutions provides a clear picture of where the system’s limits reside. Moving from 1080p to 1440p to 4K at the High setting, the average FPS goes from 57.0 to 42.6 to 31.2. This represents a 25% drop from 1080p to 1440p, and a further 27% drop from 1440p to 4K. The scaling is consistent, suggesting that the GPU’s rendering throughput is the limiting factor; as pixel count increases, the GPU must process more fragments, and the 8 GB VRAM and 224.0 GB/s bandwidth are unable to maintain frame rates.

At the Low setting, the scaling is steeper in relative terms: 1080p yields 93 FPS, 1440p drops to 74.7 FPS (a 20% reduction), and 4K yields 55.9 FPS (a 25% reduction from 1440p). The absolute FPS numbers are higher at Low settings, but the percentage drops are similar, reinforcing that the GPU’s fillrate and memory subsystem are the constraints. The CPU’s contribution is more evident at 1080p Low, where the frame rate is highest, but even at 4K Low, the system achieves 55.9 FPS, which is respectable for a flight simulator.

The data indicates that the system is GPU-bound in nearly all tested configurations. The CPU’s high single-thread score (6290 in Cinebench R23) and multi-thread score (44557) are not fully taxed, as evidenced by the FPS scaling pattern. If the CPU were the bottleneck, we would expect to see smaller FPS drops when increasing resolution, as the CPU’s workload would remain constant while the GPU’s workload increases. Instead, the consistent FPS drops across resolutions point to the GPU’s memory bandwidth and VRAM capacity as the primary limiters.

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

At 1920x1080, the system delivers an average of 93 FPS on Low settings, 71.4 FPS on Medium, 57.0 FPS on High, and 53.8 FPS on Ultra. The gap between Low and Ultra is 39.2 FPS, or a 42% reduction, indicating that the GPU’s shading units and memory are heavily utilized at higher presets. The jump from Medium to High is 14.4 FPS (20% drop), while the jump from High to Ultra is smaller at 3.2 FPS (6% drop), suggesting diminishing returns as the GPU approaches its limits.

At 2560x1440, the averages are 74.7 FPS on Low, 56.8 FPS on Medium, 42.6 FPS on High, and 38.5 FPS on Ultra. The drop from Low to Ultra is 36.2 FPS, or 48%, which is a steeper percentage decline than at 1080p. This is expected, as the pixel count increase from 1080p to 1440p (approximately 1.78x) places additional strain on the GPU’s ROPs and memory bandwidth. The Medium setting at 1440p (56.8 FPS) is comparable to the High setting at 1080p (57.0 FPS), illustrating the performance cost of higher resolution.

At 3840x2160, the averages are 55.9 FPS on Low, 43.6 FPS on Medium, 31.2 FPS on High, and 28.6 FPS on Ultra. The drop from Low to Ultra is 27.3 FPS, or 49%, the largest percentage reduction across all resolutions. The 4K Medium setting (43.6 FPS) is barely playable, while 4K High (31.2 FPS) and 4K Ultra (28.6 FPS) fall below the 30 FPS threshold, making them unsuitable for a smooth experience. The data shows that the RX 6600’s 8 GB VRAM is insufficient for 4K Ultra, as the frame rate collapses to 28.6 FPS.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i7-14700KF and AMD Radeon RX 6600 achieves a rank of 1441 out of 1795 tested combos in Microsoft Flight Simulator. This places the system in the bottom 20% of all tested configurations, which is a low standing given the CPU’s high percentile rank (96th) and the GPU’s mid-range percentile (69th). The ranking reflects the GPU’s limitations, as the RX 6600 is not a high-end card, and its performance in this simulation-heavy title is constrained by its memory bandwidth and VRAM.

The combo’s rank is influenced by the CPU’s strong synthetic scores, but in game, the GPU’s average benchmark score of 25235 is only slightly above the AMD Radeon 890M (25246) and the RX 580 2048SP (25287). The nearest rivals to the GPU, such as the RTX 3060 Ti (25120), show a deltaPct of 0.5%, meaning the RX 6600 is statistically similar in raw compute but lacks the memory capacity for high-resolution textures. This is evident in the 4K Ultra score of 28.6 FPS, which is well below the 30 FPS playability threshold.

Given the CPU’s performance, the bottleneck is unequivocally the GPU. The Core i7-14700KF’s nearest rival, the Core i7-14700K, has an average score of 70074 with a deltaPct of 0%, indicating the CPU is not the limiting factor in this pairing. The low combo rank (1441 of 1795) suggests that users would need a more powerful GPU to unlock the CPU’s full potential in Flight Simulator, particularly at higher resolutions and settings. The data shows that the system is best suited for 1080p gaming, where it can achieve 53.8 FPS on Ultra, or 1440p with Medium settings at 56.8 FPS. For 4K, only Low settings (55.9 FPS) provide a playable experience, and even then, the frame rate is marginal.
