Microsoft Flight Simulator

The Intel Core i7-14700KF paired with the Intel Arc B370 presents a starkly contrasting set of capabilities. The CPU is a high-end 20-core processor that ranks in the 94th percentile among all tested CPUs, while the GPU is an integrated-class part that sits in the 5th percentile of all tested GPUs. In Microsoft Flight Simulator, this combination produces a heavily GPU-bound experience, where the frame rate is consistently constrained by the graphics processor rather than the processor. The measured results across resolutions and settings presets provide a clear picture of this bottleneck, showing a system that can achieve playable frame rates only at the lowest settings and resolutions.

Resolution Scaling

The data reveals a classic resolution scaling curve, but the absolute frame rates are low enough that the pattern is more about degradation than optimization. At 1080p with Low settings, the combo achieves an average of 50 FPS. Moving to 1440p at the same settings drops the average to 41 FPS, a reduction of 18%. Further scaling to 4K at Low settings yields 30 FPS, which is a 27% drop from the 1440p result and a 40% drop from the 1080p baseline. This steep decline indicates that the GPU is the limiting factor; as pixel count increases, the Arc B370's fill rate and shading resources are exhausted, leading to disproportionately large frame rate losses.

At the High preset, the scaling pattern is similar but compressed. The 1080p High average is 30 FPS, which falls to 24 FPS at 1440p (a 20% decrease) and then to 18 FPS at 4K (a 25% decrease from 1440p). The fact that the 1080p High result matches the 4K Low result (both at 30 FPS) is telling: the game's render load at High settings with fewer pixels is nearly equivalent to running at Low settings with four times the pixels. This suggests that the GPU's computational ceiling is reached regardless of the specific settings mix, and the frame rate is primarily dictated by the total number of pixels processed.

The Medium preset shows a slightly more efficient scaling curve, with 39 FPS at 1080p, 32 FPS at 1440p, and 23 FPS at 4K. The percentage drops are 18% and 28%, respectively, which is consistent with the Low preset's behavior. The Ultra preset, which is the most demanding, yields 28 FPS at 1080p, 23 FPS at 1440p, and 17 FPS at 4K. The difference between 1440p Ultra and 1080p Ultra is only 5 FPS, indicating that at these low frame rates, the GPU is already saturated and additional resolution has a diminishing absolute impact. Across all presets, the jump from 1440p to 4K consistently costs roughly 25-30% of the frame rate, confirming that the Arc B370's memory bandwidth—listed as "System Dependent" and shared with the CPU—is a severe constraint at higher resolutions.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, built on a 3 nm process. Its role in this combo is the primary limiter. With a base clock of 300 MHz and a boost clock of 2400 MHz, the GPU has a nominal peak performance of 6.144 TFLOPS FP32, but the measured 3DMark Steel Nomad DX12 score of 1184 places it just 0.2% behind the ATI Mobility Radeon HD 5570 and 0.5% behind the ATI Radeon HD 5770. This level of performance is far below what modern flight simulators demand.

The GPU's memory configuration is "System Shared," meaning it uses a portion of the system's main memory rather than dedicated VRAM. The bandwidth is also "System Dependent," which in this benchmark setup translates to a severe bottleneck when rendering at 4K. The measured results show that the Ultra preset at 4K averages 17 FPS, while the Low preset at 1080p averages 50 FPS. The difference between these two extremes is a 3x improvement in frame rate by reducing both resolution and settings, underscoring how sensitive this GPU is to memory pressure and shader load.

The GPU's 1280 shading units, 40 TMUs, and 20 ROPs are modest by any standard. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are theoretical maximums that the shared memory system cannot sustain. The boost clock of 2400 MHz is respectable for an integrated part, but it does not compensate for the lack of dedicated memory bandwidth. In Microsoft Flight Simulator, which streams terrain and scenery data, the GPU's reliance on system memory causes stutter and low average frame rates, particularly at 4K where even the Medium preset only manages 23 FPS with minimums of 20 FPS. The data indicates that this GPU is only suitable for the lowest settings at 1080p, where the 50 FPS average is the sole result that approaches playability.

How This Combo Ranks

In Microsoft Flight Simulator, the combination of the Intel Core i7-14700KF and Intel Arc B370 ranks 3428 out of 3714 tested combos. This places the configuration in the bottom 7.7% of all tested systems, a position that reflects the GPU's severe performance deficit. The CPU, by contrast, is a top-tier part: its average benchmark score of 70163 places it 0.2% ahead of the AMD Ryzen 7 9700F, 0.4% ahead of the AMD Ryzen 9 7940HX, and 0.9% ahead of the AMD Ryzen 9 7950X. It is 1% behind the Intel Core Ultra 7 265K Mendocino.

The rank of 3428 out of 3714 is driven entirely by the GPU's 5th percentile standing. The Arc B370's nearest rivals are all legacy or low-power parts from over a decade ago, such as the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, indicating that this GPU is not competitive with modern discrete graphics solutions. In a game like Microsoft Flight Simulator, which is known for its heavy rendering load, the combo's low rank is expected. The data shows that even with a high-end CPU, the system cannot escape the GPU bottleneck, and the frame rates fall well below what other combos in the top quartile would achieve.

Measured FPS Breakdown

The measured FPS data covers four resolutions and four settings presets, providing a comprehensive view of the combo's capabilities. At 1920x1080, the results are as follows: Low settings produce an average of 50 FPS. Medium settings produce an average of 39 FPS, with a minimum of 33 and a maximum of 45. High settings produce an average of 30 FPS. Ultra settings produce an average of 28 FPS. The spread from Low to Ultra at 1080p is 22 FPS, with each step up in settings costing roughly 9-11 FPS on average.

At 2560x1440, the Low preset averages 41 FPS. The Medium preset averages 32 FPS, with a minimum of 27 and a maximum of 36. The High preset averages 24 FPS. The Ultra preset averages 23 FPS. The difference between Low and Ultra at 1440p is 18 FPS, a slightly smaller absolute spread than at 1080p, but the relative drop is similar. The 1440p Medium results show a narrower range (27-36 FPS) compared to 1080p Medium (33-45 FPS), indicating that the GPU's frame pacing becomes more consistent as resolution increases, albeit at lower absolute values.

At 3840x2160, the Low preset averages 30 FPS. The Medium preset averages 23 FPS, with a minimum of 20 and a maximum of 27. The High preset averages 18 FPS. The Ultra preset averages 17 FPS. The total spread at 4K is only 13 FPS from Low to Ultra, which suggests that the GPU is so constrained that changes in settings have a reduced impact on the final frame rate. The minimum FPS of 20 at 4K Medium is notable, as it indicates that the system can dip below 20 FPS in complex scenes, which would cause noticeable stuttering in a flight simulator.

Settings Recommendations

Based on the measured rows, the only preset that yields a consistently playable experience is Low at 1920x1080, which averages 50 FPS. This is the sole configuration that exceeds the 30 FPS threshold by a significant margin, providing headroom for the frame drops that occur during scenery loading. The 1440p Low preset, at 41 FPS, is also acceptable for users who prioritize resolution over detail, but it comes with an 18% performance penalty compared to 1080p Low.

For users who cannot tolerate the visual downgrade of Low settings, the Medium preset at 1080p is the next best option, averaging 39 FPS with a minimum of 33 FPS. This provides a stable experience that stays above 30 FPS in the tested scenarios. The 1440p Medium preset, averaging 32 FPS, is borderline playable, but the minimum of 27 FPS suggests occasional dips below the acceptable threshold. The High preset at 1080p, averaging 30 FPS, is the highest quality setting that maintains an average at the 30 FPS mark, but it leaves no headroom for demanding scenes.

The Ultra preset is not recommended at any resolution. The best Ultra result, 28 FPS at 1080p, is below the playable thresholdadian, and the 4K Ultra result of 17 FPS is unusable for interactive flight. The data indicates that users should prioritize resolution scaling over settings upgrades: running at 1080p Low gives a 67% higher frame rate than running at 4K Low (50 vs 30 FPS), while running at 1080p Medium gives a 70% higher frame rate than 4K Medium (39 vs 23 FPS). The optimal balance for this combo is 1080p with Medium settings, which offers a 30% improvement over 1080p High while retaining a reasonable visual quality.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture, built on a 10 nm process. Its base clock is 3.40 GHz with a boost clock of 5.60 GHz, and it has a 33 MB shared L3 cache. In synthetic benchmarks, it scores 44167 in Cinebench R23 multi-core and 6235 in single-core, with a Geekbench multi-core score of 21462. These numbers place it in the 94th percentile of all CPUs, and its nearest rivals include the AMD Ryzen 7 9700F (0.2% slower), the AMD Ryzen 9 7940HX (0.4% slower), and the AMD Ryzen 9 7950X (0.9% slower).

However, in Microsoft Flight Simulator, the CPU's role is largely secondary. The game's frame rate is dictated by the GPU, as evidenced by the fact that the 4K Low result (30 FPS) matches the 1080p High result (30 FPS). If the CPU were the bottleneck, we would expect to see a smaller difference between resolutions at the same settings, but the data shows a consistent 20-30% frame rate drop when moving from 1080p to 1440p to 4K. This indicates that the GPU is saturated at all tested resolutions.

The CPU's high single-thread performance, evidenced by a Passmark single-thread score of 4480, should be sufficient for flight simulation's physics and AI calculations. The 20 cores and 28 threads provide ample multithreading headroom, with a Passmark multithread score of 52425. The CPU's memory support for DDR4 and DDR5, with a dual-channel bus, is also adequate. The bottleneck is not the CPU's compute capability but the GPU's inability to keep up with the render load. In a system with a more capable GPU, this CPU would likely deliver much higher frame rates, but in this specific combo, the CPU's performance is effectively wasted, as the frame rates are capped by the Arc B370's limitations.
