Microsoft Flight Simulator

The Intel Core i5-12600KF is a 10-core, 16-thread Alder Lake-S desktop processor with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. Its 20 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support position it as a high-end mainstream part. In synthetic benchmarks, this CPU posts a Cinebench R23 multi-core score of 23,444 and a single-core score of 3,309, placing it at the 84th percentile of all tested CPUs. Its nearest rival, the Intel Core i9-10900K, holds an average benchmark score of 27,829, a delta of 0% compared to this chip’s 27,827 average, indicating near-identical overall compute performance. The i5-12600KF also sits within 0.4% of the Intel Core i7-13700H and just 0.1% behind the Core i5-12600K, making it a tightly clustered performer in its segment. For a flight simulator, the game’s heavy reliance on physics and world-simulation logic means these multi-threaded scores are directly relevant; the 3DMark 16-thread score of 7,956 and PassMark multi-thread score of 27,575 suggest ample headroom to feed a discrete GPU, though the single-thread PassMark score of 3,925 shows strong per-core performance, which matters for the simulator’s main render thread. The data indicates this CPU is not the limiting factor at lower resolutions, as its compute throughput comfortably exceeds what the paired GPU can deliver.

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

Microsoft Flight Simulator is famously demanding on both processor and graphics hardware, but the data from this combo shows a clear division of labor. The i5-12600KF’s 10 cores and 16 threads, with a 4.90 GHz boost clock, provide the raw instruction throughput needed to simulate terrain, weather, and aircraft systems. In the measured FPS results, at 1080p Low the combo achieves 123.3 FPS, which is the highest frame rate recorded across all settings and resolutions. This suggests that when the GPU load is minimized, the CPU can push well past 120 FPS, meaning it has substantial performance in reserve. The CPU’s nearest rival, the Intel Core i9-10900K, has an identical average benchmark score (delta 0%), so swapping between these two would yield no meaningful change in CPU-bound scenarios. However, the i5-12600KF’s 20 MB of L3 cache and 3.70 GHz base clock ensure consistent performance in long simulation sessions, where sustained loads are common. Benchmark results indicate that the CPU’s single-threaded Cinebench R20 score of 1,389 is strong, but the game’s frame pacing at 4K Ultra (37.6 FPS) is far below that threshold, proving the GPU is the bottleneck in that configuration.

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

The AMD Radeon RX 6700 XT is a 12 GB GDDR6 card with a 192-bit memory bus and 384.0 GB/s of bandwidth, paired with a boost clock of 2581 MHz and a game clock of 2424 MHz. Its 2560 shading units and 40 ray accelerators make it a capable mid-to-high-range part, but the measured FPS data reveals its limits. At 1080p Ultra, the combo averages 69.4 FPS, which drops to 56.3 FPS at 1440p Ultra and further to 37.6 FPS at 4K Ultra. This scaling pattern—a 45.8% drop from 1080p to 4K at Ultra settings—shows the GPU being progressively overwhelmed by pixel throughput demands. The card’s PassMark G3D score of 19,786 places it at the 77th percentile of all GPUs, with its nearest rival, the AMD Radeon RX 6800, scoring 33,493 in the average benchmark (a delta of 0.7% against this GPU’s 33,721). Interestingly, the RX 6700 XT also sits within 1% of the AMD Radeon HD 7950 and RX 480 in aggregate benchmark scores, though those older cards lack the 12 GB VRAM and modern feature set required for high-fidelity flight simulation. The 12 GB frame buffer is sufficient for 4K textures, but the 384.0 GB/s bandwidth becomes a limiting factor when the simulator streams large scenery tiles, explaining why High settings at 4K only yield 38.4 FPS versus 69.1 FPS at 4K Low.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the highest average FPS this combo achieves, and at which settings?

A: The highest recorded average FPS is 123.3 at 1920x1080 with Low settings. This indicates the CPU can handle the game’s logic at high frame rates when the GPU is not heavily taxed.

Q: How much faster is this combo at 1080p Ultra compared to 4K Ultra?

A: At 1080p Ultra, the average FPS is 69.4, while at 4K Ultra it drops to 37.6. This represents a 45.8% reduction in frame rate when moving from Full HD to 4K at the same settings.

Q: Which component is the primary bottleneck at 4K resolution?

A: The GPU is the limiting factor at 4K. The difference between Low (69.1 FPS) and Ultra (37.6 FPS) at 3840x2160 is substantial, showing that the RX 6700 XT’s compute and memory bandwidth are saturated by the higher resolution, whereas the CPU’s performance headroom remains untapped.

Q: How does the i5-12600KF compare to its nearest rival in raw compute?

A: The i5-12600KF has an average benchmark score of 27,827, which is identical to the Intel Core i9-10900K’s 27,829 (a delta of 0%). It is also within 0.4% of the Intel Core i7-13700H, making these CPUs effectively interchangeable in terms of aggregate performance.

Q: What is the Radeon RX 6700 XT’s memory configuration, and does it affect 4K performance?

A: The GPU has 12 GB of GDDR6 memory on a 192-bit bus, yielding 384.0 GB/s of bandwidth. At 4K High, the combo averages 38.4 FPS, which is only slightly above the 37.6 FPS at Ultra, suggesting that memory bandwidth constraints limit performance regardless of the quality preset.

Q: Where does this combo rank among all tested combinations?

A: It ranks 961st out of 1,795 tested combos, placing it in the 46.5th percentile of all systems. This indicates a mid-pack standing, consistent with the GPU’s 77th percentile and CPU’s 84th percentile scores.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core i5-12600KF and AMD Radeon RX 6700 XT combination occupies the 961st position out of 1,795 tested combos for Microsoft Flight Simulator. This mid-pack ranking is somewhat surprising given the individual component percentiles—the CPU sits at the 84th percentile and the GPU at the 77th percentile—but it reflects the game’s unique demands and the balance between these two parts. The data shows that the combo is not among the top performers, likely because the RX 6700 XT, while solid, does not have the raw pixel throughput of higher-tier cards like the RX 6800, which is only 0.7% ahead in aggregate benchmark scores. In practical terms, this ranking means that many other systems with either a faster GPU or a more balanced CPU-GPU pairing will outperform it in this simulator. The 1080p Low frame rate of 123.3 FPS is respectable, but at 4K Ultra the 37.6 FPS result is below the 60 FPS threshold that many users consider playable, pushing this combo into the lower half of the ranking. This is not a criticism of the CPU, which has ample headroom, but rather a reflection that the GPU becomes the weak link at higher resolutions, dragging the overall combo rank down relative to configurations with more powerful graphics cards.

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

The measured FPS data reveals a classic GPU-bound scaling pattern. At Low settings, the combo delivers 123.3 FPS at 1080p, 97.9 FPS at 1440p, and 69.1 FPS at 4K—a 44% drop from 1080p to 4K. At Ultra settings, the numbers are 69.4 FPS (1080p), 56.3 FPS (1440p), and 37.6 FPS (4K), a 45.8% reduction. The consistency of this drop across both Low and Ultra presets is telling: the frame loss from resolution scaling is nearly identical regardless of graphics quality, which indicates the GPU is the limiting component in all cases. If the CPU were the bottleneck, we would expect to see a smaller FPS drop at higher resolutions, since the GPU would have more time to render each frame while the CPU struggles to keep up with simulation logic. Instead, the data shows that the RX 6700 XT’s 384.0 GB/s memory bandwidth and 13.21 TFLOPS FP32 compute are simply insufficient to maintain high frame rates as pixel count increases. The 12 GB VRAM is not the issue—at 4K High (38.4 FPS) versus 4K Ultra (37.6 FPS), the difference is minimal, suggesting the card is compute-limited rather than memory-limited. In contrast, the CPU’s performance remains constant across resolutions, as evidenced by the 1080p Low result of 123.3 FPS, which shows the i5-12600KF can push far beyond what the GPU can deliver at 4K. This analysis confirms that for this combo, the Radeon RX 6700 XT is the primary constraint, and any upgrade path would need to focus on the GPU to improve 4K performance.
