GPU Role

The AMD Radeon RX 6800 XT brings 16 GB of GDDR6 memory across a 256-bit bus, delivering 512.0 GB/s of bandwidth. This memory configuration is substantial for flight simulation, where texture streaming and large world data can consume significant VRAM. The GPU's base clock runs at 1825 MHz, with a game clock of 2015 MHz and a boost clock of 2250 MHz. The RDNA 2.0 architecture, built on a 7 nm process at TSMC, contains 4,608 shading units, 288 TMUs, and 128 ROPs, with 72 ray accelerators.

In Microsoft Flight Simulator, the GPU's role becomes increasingly dominant as resolution and settings scale upward. At 1080p Low, the GPU is not the primary constraint, allowing 153 FPS. However, at 4K Ultra, the frame rate drops to 51 FPS, a 67% reduction from the 1080p Low result. This dramatic scaling indicates that the RX 6800 XT's compute throughput — rated at 20.74 TFLOPS FP32 — becomes the bottleneck at higher resolutions.

The 16 GB VRAM capacity is unlikely to be exhausted even at 4K Ultra, given the modest 8 GB delta between the lowest and highest settings at any resolution. The GPU's pixel rate of 288.0 GPixel/s and texture rate of 648.0 GTexel/s suggest it can handle the geometry and texture workloads typical of flight simulators, but the data shows that Ultra settings at 4K push the card to its limits, with only 51 FPS average. The card's 85th percentile ranking among all GPUs reinforces its position as a high-end but not flagship solution, and the 3% deficit to the RTX 5070 Ti in synthetic benchmarks aligns with the observed frame rates.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution scaling across all four settings tiers. Moving from 1080p to 1440p at High settings reduces average FPS from 90 to 72, a 20% drop. Continuing to 4K High brings the average down to 53 FPS, a further 26% reduction. This scaling behavior indicates that the GPU is the limiting component at higher resolutions, while the CPU has sufficient headroom to maintain simulation logic.

At Low settings, the scaling is more pronounced in absolute terms: 153 FPS at 1080p drops to 123 FPS at 1440p (20% reduction) and 91 FPS at 4K (26% further reduction). The relative consistency of these percentage drops across settings suggests that resolution is the dominant variable, not the complexity of the scene rendering. However, the absolute frame rates at Low settings remain high enough that even 4K produces a playable 91 FPS.

The Medium preset shows the narrowest scaling gap between 1440p and 4K: 96 FPS at 1440p versus 71 FPS at 4K, a 26% drop. The data includes min/max values for Medium settings, showing that at 1080p the range is 101-137 FPS, at 1440p it is 82-110 FPS, and at 4K it is 60-81 FPS. This narrowing range at higher resolutions indicates that frame time variance decreases as the GPU becomes more uniformly loaded.

Ultra settings exhibit the steepest absolute drop: 85 FPS at 1080p, 69 FPS at 1440p, and 51 FPS at 4K. The 34 FPS gap between 1080p and 4K Ultra (a 40% reduction) underscores that this combo is GPU-limited at the highest fidelity settings. The data suggests that users targeting 60 FPS should stay at 1440p or below for Ultra, while 4K is only viable with Low or Medium settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 153 FPS average, Medium yields 119 FPS (101 min, 137 max), High achieves 90 FPS, and Ultra drops to 85 FPS. The gap between Low and Ultra is 68 FPS, indicating that the GPU has ample headroom at this resolution even with maximum settings.

Moving to 2560x1440, the frame rates scale down proportionally. Low settings hit 123 FPS, Medium reaches 96 FPS (82 min, 110 max), High settles at 72 FPS, and Ultra manages 69 FPS. The delta between Low and Ultra narrows to 54 FPS, showing that resolution increases the GPU's workload more uniformly across settings.

At 3840x2160, the results reflect the GPU's limits. Low settings produce 91 FPS, Medium delivers 71 FPS (60 min, 81 max), High drops to 53 FPS, and Ultra bottoms out at 51 FPS. The spread between Low and Ultra compresses to 40 FPS, and the minimum FPS at Medium (60) exactly matches the threshold for smooth gameplay.

The settings scaling within each resolution is notable: at 1080p, the jump from Low to Medium costs 34 FPS, while Medium to High costs 29 FPS, and High to Ultra costs only 5 FPS. This pattern suggests diminishing returns from High to Ultra, where the additional visual fidelity consumes significant GPU resources for minimal frame rate impact. At 4K, the Low-to-Medium drop is 20 FPS, Medium-to-High is 18 FPS, and High-to-Ultra is just 2 FPS, reinforcing that Ultra provides marginal gains over High at the highest resolution.

How This Combo Ranks

The Intel Core i7-14700K paired with the AMD Radeon RX 6800 XT ranks 1,156th out of 3,714 tested combos in Microsoft Flight Simulator. This places the configuration in the upper third of all tested systems, specifically at the 68.9th percentile. The ranking reflects a balanced pairing where neither component dramatically bottlenecks the other in this title.

In the context of the GPU's synthetic benchmarks, the RX 6800 XT achieves an 85th percentile ranking among all GPUs, meaning the card outperforms 85% of tested graphics processors. The CPU's 94th percentile ranking is even higher. The combination of a top-decile CPU with a high-end GPU results in a system that ranks below what either component's percentile might suggest, indicating that Microsoft Flight Simulator's engine does not perfectly scale with the hardware's raw compute capabilities.

The 1,156th rank out of 3,714 combos suggests that many configurations with more powerful GPUs or CPUs achieve better results in this specific title. The delta to the nearest GPU rivals — 1.5% ahead of the RTX A1000 Mobile, 2.5% behind the Arc A550M, and 3% behind the RTX 5070 Ti and RX Vega 64 — shows that the RX 6800 XT sits in a competitive but not dominant position. The CPU's near-parity with the Ryzen 9 7950X (0.2% difference) means that the GPU is likely the differentiator in ranking.

CPU Role

The Intel Core i7-14700K provides 20 cores and 28 threads, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Built on the Raptor Lake architecture at Intel's 10 nm process, this processor features 33 MB of shared L3 cache and 2 MB of L2 cache per core. The CPU's benchmark results are impressive: Cinebench R23 multi-core scores 33,440.5, single-core 2,160; Geekbench multi-core reaches 20,767 and single-core 2,569; PassMark multi-thread scores 52,392.

In Microsoft Flight Simulator, the CPU's role is critical for managing the simulation's physics, AI, and world streaming. The 20-core configuration provides substantial parallel processing capability, as evidenced by the Cinebench R20 multi-core score of 18,544. The high boost clock of 5.60 GHz contributes to strong single-thread performance, which is essential for the main simulation loop that cannot be fully parallelized.

The data shows that at 1080p Low settings, the combo achieves 153 FPS, suggesting the CPU can feed the GPU sufficiently at this resolution. However, the 94th percentile ranking among all CPUs indicates that the i7-14700K is not the limiting factor in most scenarios. The nearest rival, the AMD Ryzen 9 7950X, scores 69,515 versus the Intel's 69,355 — a 0.2% difference that translates to virtually identical real-world performance. The AMD EPYC 9115 trails by just 0.1%, while the Ryzen 9 7940HX and Ryzen 7 9700F are 0.7% and 0.9% ahead, respectively.

The CPU's memory support for both DDR4 and DDR5, along with its dual-channel memory bus, provides flexibility for system builders. The 125 W TDP and unlocked multiplier allow for overclocking, though the data provided does not include overclocked results. The PassMark data compression score of 695,234 and encryption score of 40,091 suggest strong general-purpose performance that benefits the simulation's background tasks. The physics score of 2,964 in PassMark further indicates robust computational capability for flight dynamics calculations.
