Microsoft Flight Simulator

The pairing of the Intel Core i7-14700K with the AMD Radeon RX 570 presents a stark contrast in capabilities. The data places this combination at rank 3538 out of 3714 tested combos for Microsoft Flight Simulator, placing it in the bottom 5% of all systems. This is a configuration where a high-end, 20-core processor is paired with a GPU that was end-of-life as of its 2017 release, creating a significant bottleneck that defines the entire performance profile. The benchmark results indicate that this system struggles to maintain playable frame rates at most settings, with the CPU's potential largely unrealized due to the GPU's limitations.

Resolution Scaling

The FPS drop from 1080p to 4K is sharp and consistent across all settings, revealing a system that is heavily constrained by the graphics card. At Low settings, the average frame rate falls from 48 FPS at 1920x1080 to 39 FPS at 2560x1440, a reduction of 9 FPS. Moving to 3840x2160 at Low settings, the average drops further to 29 FPS. This represents a 39.6% decrease in performance from 1080p to 4K, a pattern that indicates the GPU is the primary limiting factor. The scaling suggests that as resolution increases, the demand on the GPU's pixel and texture processing capabilities grows exponentially, overwhelming the RX 570.

The trend is even more pronounced at higher settings. At Medium settings, the average FPS is 38 at 1080p, 30 at 1440p, and 22 at 4K. This shows a 21.1% drop from 1080p to 1440p and a further 26.7% drop from 1440p to 4K. The data implies that the RX 570's 4 GB of GDDR5 memory and 224.0 GB/s bandwidth are insufficient for the higher resolution textures and effects, causing a more severe performance penalty than what would be seen on a more balanced system. The scaling curve is not linear; it steepens at higher resolutions, which is typical for a GPU-bound scenario.

At Ultra settings, the frame rates become critically low, with averages of 27 FPS at 1080p, 22 FPS at 1440p, and 16 FPS at 4K. The drop from 1080p to 1440p is 5 FPS, and from 1440p to 4K is 6 FPS. While the absolute numbers are low, the relative scaling is less severe than at lower settings, suggesting that the game is already so demanding at Ultra that even the step down to a lower resolution cannot fully compensate for the GPU's lack of raw compute power. The data shows that the limiting component is unequivocally the graphics card, as the CPU's performance headroom is not being utilized.

GPU Role

The AMD Radeon RX 570's role is defined by its specifications, which are dated relative to the game's demands. It features a Polaris 20 chip on a 14 nm process, with a base clock of 1168 MHz and a boost clock of 1244 MHz. This results in a peak FP32 performance of 5.095 TFLOPS. The GPU's 4 GB of GDDR5 memory operates at 1750 MHz (7 Gbps effective) across a 256-bit bus, yielding a bandwidth of 224.0 GB/s. These figures are modest by modern standards, and the benchmark results show how they translate into sub-30 FPS averages at most configurations.

The data suggests that the VRAM capacity is a critical constraint. At 4K Ultra, the average FPS is 16, and at 4K High, it is 17. These are nearly identical, which implies that the game is not being limited by the settings' computational load but rather by the memory capacity or bandwidth. The RX 570's 4 GB frame buffer is likely being saturated at these resolutions, forcing the game to stream textures from system memory, which severely impacts performance. The GPU's percentile rank of 74 versus all GPUs is misleading in this context; its average benchmark score of 28766 places it near the Radeon RX 6800M, but in a real-world scenario like this flight simulator, it is clearly outmatched.

The GPU's memory bandwidth of 224.0 GB/s is another limiting factor. Microsoft Flight Simulator is known for streaming vast amounts of terrain and photogrammetry data, which requires high memory throughput. The benchmark results show that at 1080p Low, the system achieves 48 FPS, which is the highest score recorded. This indicates that even at the lowest settings, the GPU is working at its limit to feed the engine data. The clocks of 1168 MHz base and 1244 MHz boost are low compared to the CPU's potential, and they cannot be increased to compensate for the architectural deficiencies of the GCN 4.0 design.

CPU Role

The Intel Core i7-14700K is a formidable processor with 20 cores and 28 threads, running at a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It has a substantial 33 MB of shared L3 cache and supports dual-channel DDR4 or DDR5 memory. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 33440.5 and a single-core score of 2160. The CPU's percentile rank of 94 versus all CPUs indicates it is in the top 6% of processors, and its average benchmark score of 69355 is nearly identical to the AMD Ryzen 9 7950X, with a delta of -0.2%.

However, in this specific game, the CPU's role is diminished. The data shows that the frame rates are consistently low across all resolutions, which would not be the case if the CPU were the bottleneck. A capable processor like the i7-14700K should be able to maintain high frame rates in CPU-bound scenarios, but the measured FPS suggests that the GPU is preventing the CPU from ever becoming the limiting factor. The CPU's high multi-threaded performance, as evidenced by its Passmark multi-thread score of 52392, is irrelevant when the GPU can only render 17 FPS at 4K High.

The CPU's single-core performance is also strong, with a Geekbench single-core score of 2569. This is crucial for Microsoft Flight Simulator, which is known to be sensitive to single-thread performance. Yet, even with this strength, the system cannot achieve playable frame rates at higher settings. The data implies that the CPU is waiting for the GPU to complete its rendering tasks, and its vast processing power is left idle. The nearest rivals for the CPU, such as the AMD Ryzen 9 7950X with a delta of -0.2% and the AMD Ryzen 7 9700F with a delta of -0.9%, all share a similar fate when paired with this GPU—they are all held back by the graphics card's limitations.

How This Combo Ranks

This combination ranks 3538 out of 3714 tested combos, placing it in the 95.2nd percentile from the bottom. This is an exceptionally poor ranking, indicating that nearly 95% of all tested systems perform better in this game. The data suggests that this is a fundamentally unbalanced pairing, where the CPU's high performance is negated by the GPU's inability to keep pace. The combo's rank is not a reflection of the CPU's capabilities but rather proof of the GPU's severe bottleneck.

When comparing the GPU to its nearest rivals, the RX 570's average benchmark score of 28766 is only 0.4% higher than the Radeon RX 6800M and 0.7% higher than the Radeon R9 M295X. However, these are synthetic benchmark scores that do not reflect real-world gaming performance. In this game, the GPU's limitations are exposed, and the combo's rank suffers accordingly. The CPU's nearest rivals, such as the AMD Ryzen 9 7950X, have negligible performance deltas, but this does not help the combo's position because the GPU is the limiting factor.

The data implies that for a game like Microsoft Flight Simulator, the ranking is heavily weighted by the GPU's performance. A system with a weaker CPU but a stronger GPU would likely rank significantly higher. The i7-14700K's power is wasted in this configuration, as the system can only achieve an average of 48 FPS at 1080p Low, which is the best-case scenario. The combo's rank of 3538 out of 3714 suggests that this is not a viable configuration for a smooth experience, and the data strongly indicates that the GPU must be upgraded to unlock the CPU's potential.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's performance across resolutions and settings. At 1920x1080, the system achieves an average of 48 FPS at Low settings, 38 FPS at Medium, 28 FPS at High, and 27 FPS at Ultra. The Medium setting has a minimum FPS of 32 and a maximum of 43, showing some variance. The data shows a clear drop from Low to Medium of 10 FPS, but the difference between High and Ultra is only 1 FPS, indicating a plateau where the GPU is fully saturated.

At 2560x1440, the averages are 39 FPS at Low, 30 FPS at Medium, 23 FPS at High, and 22 FPS at Ultra. The Medium setting here has a minimum of 26 FPS and a maximum of 35 FPS. The drop from Low to Medium is 9 FPS, and from High to Ultra is only 1 FPS, again showing a compression of performance at higher settings. The data reveals that at 1440p, even the Low setting cannot maintain a consistent 60 FPS, with an average of 39 FPS.

At 3840x2160, the averages are 29 FPS at Low, 22 FPS at Medium, 17 FPS at High, and 16 FPS at Ultra. The Medium setting has a minimum of 19 FPS and a maximum of 26 FPS. The data shows a drastic drop from Low to Medium of 7 FPS, and the High and Ultra settings are nearly identical, with only 1 FPS separating them. This pattern suggests that the GPU's memory bandwidth and capacity are the primary constraints at 4K, as increasing settings beyond Medium has minimal impact on the already low frame rates.

Settings Recommendations

Based on the measured data, the only viable setting for this combo is 1920x1080 with Low settings, which yields an average of 48 FPS. This is the only configuration that provides a frame rate close to a playable level, though it is still below the 60 FPS ideal. The data shows that any increase in resolution or settings results in a significant drop in performance, with the system falling below 30 FPS at 1440p High and 4K Low.

At 1920x1080 Medium, the average FPS is 38, which is a 10 FPS drop from Low. This is a substantial decrease for a modest visual improvement, and the minimum FPS of 32 suggests that there could be noticeable stutters. The High and Ultra settings at 1080p are not recommended, as they both average below 30 FPS, making the game feel sluggish and unresponsive. The data indicates that the GPU is the bottleneck, so lowering settings has a more significant impact than lowering resolution.

For 2560x1440, the Low setting is the only option that averages above 30 FPS at 39 FPS. However, the Medium setting at 30 FPS is borderline, and the High and Ultra settings at 23 and 22 FPS respectively are not playable. At 3840x2160, all settings are below 30 FPS, with the Low setting at 29 FPS being the highest. The data suggests that 4K is not a viable option for this system.
