# Microsoft Flight Simulator — Intel Core i7-14700KF + Intel Arc B390

The Intel Core i7-14700KF paired with the Intel Arc B390 produces a fundamentally GPU-limited experience in Microsoft Flight Simulator, with the integrated graphics solution constraining frame rates across all tested resolutions and presets. The data shows a consistent pattern: even at 1080p Low, the system achieves only 56 FPS average, and performance degrades predictably as resolution increases. The combo ranks 3302 out of 3714 tested combinations, placing it in the bottom 11% of all configurations, which reflects the Arc B390's position as an integrated graphics part with a 9th percentile standing among all GPUs.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a system where the GPU is the overwhelming bottleneck. At Low settings, the transition from 1920x1080 (56 FPS) to 2560x1440 (45 FPS) represents a 19.6% performance reduction, while moving from 1440p to 3840x2160 (33 FPS) incurs a further 26.7% drop. The cumulative 1080p-to-4K loss at Low settings is 41.1%, which is substantial but not catastrophic for a flight simulator where terrain and scenery rendering dominate.

At Medium settings, the scaling pattern shifts slightly. The 1080p result of 43 FPS drops to 35 FPS at 1440p (18.6% reduction), then to 26 FPS at 4K (25.7% reduction from 1440p). Interestingly, the High preset shows a different trajectory: 33 FPS at 1080p, 26 FPS at 1440p (21.2% reduction), and 19 FPS at 4K (26.9% reduction from 1440p). The Ultra preset mirrors High closely, with 31 FPS at 1080p, 25 FPS at 1440p, and 19 FPS at 4K.

The consistent 19 FPS ceiling at 4K for both High and Ultra presets suggests that the Arc B390 hits a hard computational limit around that frame rate, regardless of which high-fidelity preset is selected. The resolution scaling behavior indicates that pixel throughput is the primary constraint — the 24 ROPs and 60.00 GPixel/s pixel rate on this GPU simply cannot sustain higher fill rates at 4K. The gap between Low and Medium settings narrows at higher resolutions, from 23.3% at 1080p (56 vs 43 FPS) to 21.2% at 1440p (45 vs 35 FPS) and 21.2% at 4K (33 vs 26 FPS), suggesting that the settings-related workload scales somewhat independently from resolution.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Panther Lake chip, using the Xe3-LPG architecture manufactured on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz, with system-shared memory providing both capacity and bandwidth that are system-dependent. The GPU's 3DMark Steel Nomad DX12 score of 1482 places it at the 9th percentile among all GPUs, with nearest rivals including the NVIDIA GeForce GT 520MX (1463, 1.3% ahead of the B390) and the NVIDIA GeForce 800M (1460, 1.5% ahead).

The shared memory architecture means that the Arc B390 has no dedicated VRAM — the memory size, type, and bus width are all listed as "System Shared," with bandwidth described as "System Dependent." This creates a direct coupling between CPU memory performance and GPU memory throughput, which is particularly relevant for Microsoft Flight Simulator's large terrain and scenery datasets. The GPU's 80 W TDP and IGP slot width confirm its integrated nature, with no power connectors and display outputs dependent on the portable device.

Benchmark results indicate that the Arc B390's compute capabilities are limited: 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores deliver 7.680 TFLOPS FP32 performance. The 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are modest figures that explain the observed frame rates. At 4K Ultra, the 19 FPS average matches the 4K High result exactly, indicating that the GPU's rendering pipeline saturates before preset quality differences can manifest. The 2.5% gap between the B390 and the GT 625 OEM (1446) in synthetic benchmarks translates to the real-world performance differential seen in this game's measured results.

CPU Role

The Intel Core i7-14700KF provides substantial compute headroom that the Arc B390 cannot fully utilize in this title. With 20 cores and 28 threads, the CPU operates at a 3.40 GHz base clock and 5.60 GHz boost clock, built on Raptor Lake architecture with a 10 nm process. The 125 W TDP and Intel Socket 1700 mounting indicate a desktop-class processor, and the unlocked multiplier allows for overclocking headroom that the benchmark data cannot directly quantify.

The CPU's benchmark scores demonstrate strong multi-threaded capability: Cinebench R23 multi-core reaches 44167, while single-core scores hit 6235. Geekbench results show 21462 multi-core and 2578 single-core. PassMark multi-thread testing yields 52425, with floating point math at 134393 and integer math at 183056. These figures place the i7-14700KF at the 94th percentile among all CPUs, with nearest rivals including the AMD Ryzen 7 9700F (69996 average, 0.2% behind) and the AMD Ryzen 9 7940HX (69875, 0.4% behind). The CPU sits 1% ahead of the Intel Core Ultra 7 265K (70879).

The 33 MB shared L3 cache and 2 MB per-core L2 cache provide ample data locality for flight simulation workloads, which often involve streaming terrain data. The 80 KB per-core L1 cache further supports rapid access to frequently used data structures. However, the measured FPS results show that even the CPU's substantial processing power cannot compensate for the GPU's limitations — at 1080p Low, the system reaches only 56 FPS despite the CPU being capable of far higher frame rates in CPU-bound scenarios. The 0.9% performance gap relative to the AMD Ryzen 9 7950X in average benchmark scores is irrelevant in this pairing, as the GPU saturates well before CPU differences become measurable.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. Low settings produce 56 FPS average, Medium achieves 43 FPS with a minimum of 37 and maximum of 50, High reaches 33 FPS, and Ultra drops to 31 FPS. The step from Low to Medium costs 13 FPS (23.2% reduction), while Medium to High loses 10 FPS (23.3%), and High to Ultra costs only 2 FPS (6.1%). This pattern suggests diminishing returns from preset quality increases beyond Medium.

Moving to 2560x1440, all presets lose approximately 20-24% of their 1080p performance. Low settings produce 45 FPS, Medium reaches 35 FPS with a range of 30-40, High achieves 26 FPS, and Ultra delivers 25 FPS. The gap between High and Ultra narrows to just 1 FPS at 1440p, while Medium maintains a 9 FPS advantage over High (34.6% faster). At this resolution, the 4K scaling trend begins to emerge, with the GPU's pixel throughput becoming increasingly dominant.

At 3840x2160, the performance floor becomes apparent. Low settings achieve 33 FPS, Medium reaches 26 FPS with a minimum of 22 and maximum of 30, while both High and Ultra plateau at 19 FPS. The Medium preset's minimum of 22 FPS indicates occasional dips that could affect gameplay smoothness, while the High and Ultra results show no variance data, suggesting consistent operation at the GPU's ceiling. The 14 FPS gap between Low and Ultra at 4K (42.4% reduction) is smaller than the corresponding 25 FPS gap at 1080p (44.6% reduction), demonstrating the GPU's absolute frame rate limit.

How This Combo Ranks

The combination of Intel Core i7-14700KF and Intel Arc B390 ranks 3302 out of 3714 tested combinations in Microsoft Flight Simulator, placing it in the 88.9th percentile from the bottom. This ranking reflects the extreme mismatch between the CPU's 94th percentile standing and the GPU's 9th percentile position. The combo's rank is driven almost entirely by the GPU's limited capabilities, as the CPU would rank far higher if paired with a more capable graphics solution.

The benchmark results indicate that this pairing is among the bottom 11% of all tested configurations for this game, which is consistent with the Arc B390's nearest rival comparisons. The GPU's 3DMark Steel Nomad score of 1482 places it just 1.3% ahead of the GT 520MX and 2.7% ahead of the GT 710, both of which are entry-level parts from previous generations. The data shows no scenario where this combo approaches playable frame rates at high quality settings — even the best result (1080p Low at 56 FPS) is marginal for a flight simulator where smooth camera movement is essential.

Settings Recommendations

Based on the measured FPS data, the Medium preset at 1920x1080 offers the best balance of visual quality and performance. This configuration produces 43 FPS average with a minimum of 37 FPS, keeping frame times within a range that avoids significant stutter. The 37 FPS minimum is the highest minimum among all presets at any resolution, and the 50 FPS maximum shows headroom for less demanding scenes.

At 2560x1440, the Low preset is the only viable option, delivering 45 FPS average. The Medium preset at this resolution drops to 35 FPS with a 30 FPS minimum, which may approach the threshold where flight simulation controls feel unresponsive. The High and Ultra presets at 1440p, at 26 and 25 FPS respectively, are below the smoothness threshold for this genre.

For 4K operation, the Low preset at 33 FPS is the only configuration that approaches acceptable performance, though the Medium preset's 26 FPS average with 22 FPS minimum may be tolerable for static flight phases. The High and Ultra presets at 19 FPS are not recommended for any scenario, as the frame rate falls below the minimum for comfortable interaction with cockpit instruments and scenery panning. Users prioritizing visual fidelity over frame rate should select Medium at 1080p, which provides a 37 FPS minimum while offering enhanced textures and effects over Low.
