Microsoft Flight Simulator

# CPU Role

The Intel Core i5-14600KF pairs 14 cores and 20 threads with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. This is a 10 nm Raptor Lake-R part on the Intel Socket 1700 platform, with 24 MB of shared L3 cache and 2 MB of L2 cache per core. For a flight simulator like Microsoft Flight Simulator, the CPU handles the heavy simulation logic, physics calculations, and AI traffic that run continuously in the background.

The benchmark data shows this processor sits at the 93rd percentile against all CPUs, which is strong for a desktop chip. Its closest rival is the Intel Core i5-14600K, which scores only 0.4% higher on average benchmark results. The AMD EPYC 4345P leads the i5-14600KF by 0.5%, while the AMD Ryzen 9 5950X trails by 0.6%. In practical terms, the i5-14600KF is in very tight company at the top of its performance tier.

Cinebench R23 results reinforce this positioning: the multi-core score of 32889 and single-core score of 4643 indicate a processor that excels in both heavily threaded and lightly threaded workloads. This matters for Microsoft Flight Simulator because the game's frame rate at lower resolutions and lower graphics settings becomes increasingly dependent on single-thread performance. The 5.30 GHz boost clock gives the CPU substantial headroom for those simulation-heavy frames.

The CPU's Geekbench scores — 15636 multi-core and 2778 single-core — further confirm its balanced capability. The PassMark single-thread score of 4273 is particularly relevant for flight sim, where the main thread often becomes the bottleneck before the GPU does, especially at 1080p. The CPU's 125 W TDP and unlocked multiplier make it a practical choice for builders who want to push performance with adequate cooling, though the data here reflects stock operation.

In the measured FPS results, the CPU's influence is visible when comparing the Low preset across resolutions. At 1920x1080 Low, the combo hits 49.4 FPS, but at 2560x1440 Low it drops to 38.8 FPS, and at 3840x2160 Low it falls to 26.9 FPS. This scaling pattern suggests that even at Low settings, the GPU is starting to become a limiting factor as resolution climbs, but the CPU is doing its part to keep frame rates from collapsing entirely.

# GPU Role

The AMD Radeon RX 570 is a Polaris 20 chip built on a 14 nm process for the RX 500 series. It carries 4 GB of GDDR5 memory on a 256-bit bus, yielding 224.0 GB/s of bandwidth. Its base clock runs at 1168 MHz with a boost of 1244 MHz, and memory operates at 1750 MHz (7 Gbps effective). The GPU packs 2048 shading units, 128 texture mapping units, and 32 ROPs, producing 5.095 TFLOPS of FP32 compute.

The RX 570 ranks at the 74th percentile among all GPUs, which is modest by modern standards. Its average benchmark score of 30158 places it within 0.2% of the NVIDIA GeForce RTX 5060 and the AMD Radeon RX 7700 XT, a remarkably tight grouping. The NVIDIA Tesla M60 trails by 0.6%, and the NVIDIA GeForce RTX 5070 Mobile is 0.8% behind. This indicates the RX 570 is performing at a level roughly equivalent to those newer cards in synthetic tests, despite being an older design.

For Microsoft Flight Simulator specifically, the GPU's 4 GB VRAM capacity is a crucial constraint. The game is known for streaming large textures, and the measured FPS data shows the GPU struggling more as settings increase. At 3840x2160 Ultra, the combo manages only 17.4 FPS, whereas at 3840x2160 Low it reaches 26.9 FPS. The gap between Low and Ultra at 4K is 9.5 FPS, showing how much headroom the graphics settings control.

The RX 570's 224.0 GB/s memory bandwidth and 256-bit bus are adequate for the game's data demands at lower settings, but the 4 GB frame buffer becomes a liability at higher resolutions. The texture rate of 159.2 GTexel/s and pixel rate of 39.81 GPixel/s are sufficient for the workloads imposed by flight sim, yet the GPU clearly bottlenecks at 4K regardless of preset. Its DirectX 12 (12_0) support means the game can use modern rendering paths, but the underlying GCN 4.0 architecture is dated.

# Settings Recommendations

The measured FPS data points to a clear best experience for this combo. At 1920x1080, the Low preset delivers 49.4 FPS, which is the highest result across all tested configurations. The Medium preset at 35.4 FPS is playable, but the jump from Low to Medium costs 14 FPS, a substantial hit for a flight simulator where smoothness matters during landing approaches and dense scenery.

At 2560x1440, the Low preset yields 38.8 FPS, while Medium drops to 30 FPS exactly. The High preset falls to 20.5 FPS, and Ultra bottoms out at 19.4 FPS. For 1440p users, Low is the only preset that stays comfortably above 30 FPS, and even then it's not a locked 60. The Medium preset at exactly 30 FPS is borderline, but the data suggests it will feel choppy in busy areas.

At 3840x2160, no preset reaches 30 FPS. Low manages 26.9 FPS, Medium hits 21.5 FPS, High sits at 20.1 FPS, and Ultra drops to 17.4 FPS. The data indicates that 4K is not a viable target for this combination — even the lowest settings fail to achieve a smooth frame rate.

The best overall experience per the measured rows is 1920x1080 Low at 49.4 FPS. This gives the highest average frame rate and leaves the most headroom for the simulation overhead that Microsoft Flight Simulator imposes. If a user wants better visual quality, 1920x1080 Medium at 35.4 FPS is the next reasonable step, but the trade-off is a 28% reduction in average FPS. For this pairing, prioritizing frame rate over visual fidelity is the practical recommendation.

# How This Combo Ranks

The combo rank for this pairing in Microsoft Flight Simulator is 1737 out of 1795 tested combinations. That places it in the bottom 3.2% of all combos in the database, which is a poor showing. The data makes clear that the RX 570 is the limiting factor — the CPU is a top-tier performer, but the GPU holds the entire system back.

The rank reflects the reality that Microsoft Flight Simulator is a demanding title, and the RX 570's 4 GB VRAM and older architecture are not well suited to its requirements. The 74th percentile GPU ranking translates into a much worse in-game rank because the game's engine is heavily optimized for newer hardware with larger frame buffers and more compute throughput.

For context, the CPU's 93rd percentile ranking versus the GPU's 74th percentile shows a significant mismatch. Builders considering this pairing should understand that the CPU has substantial headroom left on the table. Upgrading the GPU would yield a far larger performance improvement than upgrading the CPU, based on the benchmark data available.

# Measured FPS Breakdown

At 1920x1080, the combo delivers: Low 49.4 FPS, Medium 35.4 FPS, High 26.7 FPS, Ultra 30.1 FPS. The Ultra result is interesting because it is higher than High by 3.4 FPS, which may reflect variance in the simulator's workload during the measurement window.

At 2560x1440, the results are: Low 38.8 FPS, Medium 30 FPS, High 20.5 FPS, Ultra 19.4 FPS. The drop from Medium to High is 9.5 FPS, which is a steep penalty for the visual upgrade. The gap between High and Ultra is only 1.1 FPS, suggesting diminishing returns at the top end.

At 3840x2160, the results are: Low 26.9 FPS, Medium 21.5 FPS, High 20.1 FPS, Ultra 17.4 FPS. The difference between Low and Ultra is 9.5 FPS, and no setting crosses the 30 FPS line. The scaling from 1440p to 4K at Low settings is a drop from 38.8 to 26.9 FPS, an 11.9 FPS reduction that highlights the GPU's memory bandwidth limitations.

Across all resolutions, the Low preset consistently delivers the highest frame rates by a wide margin. The Medium preset is the only other option that approaches playable levels, and only at 1080p and 1440p. The data shows this combo is best suited for 1080p Low, with 1440p Low as a possible alternative for users who prioritize resolution over frame rate.
