Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that stresses both processor and graphics hardware, and the combination of the AMD Ryzen 5 8400F and Intel Arc B570 produces a specific performance profile that varies significantly with resolution and settings. The measured data shows a system that can deliver playable frame rates at 1080p, but struggles to maintain smooth performance at higher resolutions, particularly when visual fidelity is maxed out.

Resolution Scaling

The frame rate data clearly illustrates how the Intel Arc B570 becomes the primary limiting factor as resolution increases. At 1920x1080 with Low settings, the system achieves an average of 86 FPS, which drops to 69 FPS at 2560x1440 and further to 51 FPS at 3840x2160. This progression represents a 40.7% reduction in performance from 1080p to 4K at Low settings, indicating a substantial load increase on the GPU.

The scaling pattern becomes even more pronounced when examining High settings. The average frame rate falls from 50 FPS at 1080p to 41 FPS at 1440p, then plummets to 30 FPS at 4K. This represents a 40% drop from 1080p to 4K, showing that the Arc B570's 10 GB of VRAM and 160-bit memory bus are being saturated as pixel count increases. The 4K High result of 30 FPS is borderline playable, but the 28 FPS Ultra result at the same resolution falls below the threshold for smooth gameplay.

The data suggests that at 1080p, the system is more balanced, with the CPU able to keep the GPU adequately fed. However, as resolution climbs, the GPU's computational limits become evident. The transition from Medium to Ultra settings at 1440p shows a drop from 54 FPS to 39 FPS, a 27.8% decrease, which is less severe than the resolution scaling but still significant. At 4K, the jump from Low to Ultra costs 23 FPS, representing a 45.1% performance penalty, highlighting how the combination of high resolution and demanding settings overwhelms this GPU.

GPU Role

The Intel Arc B570, based on the Xe2-HPG architecture and built on a 5 nm process at TSMC, operates with a consistent 2500 MHz base and boost clock. Its 2304 shading units and 144 texture mapping units provide the raw compute power, but the 10 GB of GDDR6 memory on a 160-bit bus delivering 380.0 GB/s of bandwidth is a potential bottleneck in a game like Microsoft Flight Simulator, which is known for loading large textures and complex scenery.

The GPU's benchmark scores place it in the 65th percentile of all GPUs, with an average benchmark score of 20556. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile, which scores 20534 with a deltaPct of 0.1%, and the Intel Arc A750, which scores 20582 with a deltaPct of -0.1%. This indicates the B570 is positioned competitively within its performance class, trading blows with mobile and previous-generation desktop parts.

In terms of real-world gaming performance, the measured FPS shows that the GPU's capabilities are stretched at higher resolutions. The 4K Ultra result of 28 FPS suggests the card's 11.52 TFLOPS of FP32 compute and 200.0 GPixel/s pixel rate are insufficient for maximum settings at 4K. However, the 1080p Low result of 86 FPS demonstrates that the card can deliver high frame rates when the workload is less demanding. The GPU's TDP of 150 W and suggested 450 W PSU indicate it is a mid-range power draw part, and its dual-slot form factor with a 272 mm length makes it a standard install in most cases.

The memory bandwidth of 380.0 GB/s is a key differentiator. At 1080p, this seems adequate, but at 4K, the demand for texture data increases exponentially. The data shows a 28 FPS average at 4K Ultra, which is 41.9% lower than the 48 FPS at 1080p Ultra. This disproportionate drop suggests that the VRAM capacity and bandwidth are limiting factors, preventing the GPU from maintaining performance as resolution scales.

CPU Role

The AMD Ryzen 5 8400F, a Zen 4 (Phoenix) architecture part built on TSMC's 4 nm process, provides 6 cores and 12 threads with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. Its 16 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s of bandwidth are modern specifications that should handle flight simulation's often single-thread-heavy workloads.

The CPU's benchmark results show it sits in the 77th percentile of all CPUs, with an average benchmark score of 25005. Its nearest rivals include the AMD Ryzen 5 7500F, which scores 24964 with a deltaPct of 0.2%, and the Intel Core i7-13620H, which scores 24911 with a deltaPct of 0.4%. This places the 8400F in a strong position, slightly ahead of these comparable parts in overall processing power.

In Microsoft Flight Simulator, the CPU's role is critical for physics calculations, flight dynamics, and AI traffic management. The single-thread performance, evidenced by a 3dmark_single_thread score of 951 and a Cinebench R23 single-core score of 2943, is solid for a 6-core part. The multi-thread scores, such as the Cinebench R23 multicore result of 20851, show that it can handle parallel workloads well, which is beneficial for the game's background tasks.

The measured FPS data suggests the CPU is not the limiting factor at higher resolutions. For example, at 1080p Low, the system achieves 86 FPS, while at 4K Low, it drops to 51 FPS. This 40.7% reduction is primarily attributable to the GPU, as the CPU's workload does not increase proportionally with resolution. The 8400F's 65 W TDP and unlocked multiplier make it a flexible option for overclocking, though the data here reflects stock performance.

How This Combo Ranks

The combination of the AMD Ryzen 5 8400F and Intel Arc B570 ranks 2406 out of 2996 tested combos in Microsoft Flight Simulator. This places it in the bottom 20% of all combinations, indicating that while the individual components are competent, their pairing is not optimal for this specific game.

This ranking is somewhat surprising given the CPU's strong performance in synthetic benchmarks. The 8400F's 77th percentile ranking among all CPUs suggests it should be capable of driving higher frame rates. However, the GPU's 65th percentile ranking, combined with the game's demanding nature, drags the combo down. The data shows that at 1080p Low, the combo achieves 86 FPS, which is respectable, but at 4K Ultra, it falls to 28 FPS, which is below playable thresholds.

Comparing to the nearest rivals, the GPU's performance is closely matched with the RTX 3070 Mobile and Arc A750, differing by less than 0.5% in synthetic benchmarks. However, the combo rank suggests that in real-world gaming scenarios, other factors such as driver optimization and memory bandwidth play a more significant role. The 10 GB VRAM capacity may be insufficient for ultra-high texture settings at 4K, as evidenced by the 28 FPS result.

The rank of 2406 out of 2996 indicates that most other combinations tested provide better performance in Microsoft Flight Simulator. This could be due to the Arc B570's relatively low memory bandwidth compared to higher-end GPUs, or the specific architectural choices made by Intel that may not align perfectly with this game's engine. For users seeking higher frame rates, this combo may require lowering settings or resolution to achieve smooth gameplay.

| 1920x1080 | Medium | 67 | 57 | 77 |

| 1920x1080 | Ultra | 48 | - | - |

The data reveals a clear trend: at 1080p, the system is capable of delivering high frame rates, with the Low setting achieving 86 FPS and the Medium setting hitting 67 FPS. The Ultra setting at 1080p still provides a playable 48 FPS. As resolution increases to 1440p, the frame rates drop by approximately 20-25%, with the High setting falling from 50 to 41 FPS and the Ultra setting from 48 to 39 FPS. At 4K, the system struggles, with only the Low setting exceeding 50 FPS, and the Ultra setting dipping to 28 FPS.

The Medium settings provide the most complete data, with minimum and maximum frame rates recorded. At 1080p Medium, the system ranges from 57 to 77 FPS, averaging 67. At 1440p Medium, the range is 46 to 62 FPS, averaging 54. At 4K Medium, the range narrows to 34 to 46 FPS, averaging 40. This data suggests that the Medium preset is the sweet spot for maintaining consistent performance across resolutions, though the 4K result may still feel choppy to some users.

The performance delta between Low and Ultra settings is substantial. At 1080p, the difference is 38 FPS (86 to 48), representing a 44.2% reduction. At 1440p, the difference is 30 FPS (69 to 39), a 43.5% reduction. At 4K, the difference is 23 FPS (51 to 28), a 45.1% reduction. This consistency indicates that the GPU's performance scaling is linear across resolutions, with the same relative penalty for increasing graphical fidelity.
