Microsoft Flight Simulator

Microsoft Flight Simulator’s measured data for the Intel Core i5-13400F and Intel Arc B370 paints a clear picture: a capable Raptor Lake CPU mated to a severely underpowered iGPU. That is a single integrated graphics part with a 300 MHz base and 2400 MHz boost, a 20% TDP of 25W and a 5th percentile rating among all GPUs. The result—best average of 50 FPS at 1080p Low and 17 FPS at 4K Ultra—places the combo at rank 3428 out of 3714 tested combinations, but a good processor keeps the results predictable and easy to optimize around. This is, underneath it all, a configuration that will reward lowering resolution steps first and dialing settings second.

Resolution Scaling

The measured rows show monotonic frame-rate loss as resolution climbs. At Medium preset the average drops from 39 FPS at 1920x1080 to 32 at 2560x1440 and then to 23 at 3840x2160. The same pattern repeats more sharply on High (30 → 24 → 18) and on Ultra (28 → 23 → 17). Low preserves the largest averages: 50, 41 and 30 across the same three resolutions.

The slope from 1440p to 4K is noticeably steeper than from 1080p to 1440p in every setting. Medium loses 7 frames between 1080p and 1440p, then another 9 frames on the jump to 4K. Low keeps a nearly linear drop: 50 → 23 → 30 skips but each step is 9 and 11 frames. High shows a consistent 6 frame drop at each step, while Ultra stays above 20 frames only at 1080p, dropping to 23 at 1440p and finally 17 at 4K. This print tells us that the limit lies in the GPU pipeline rather than the CPU: If the processor were the constraint, resolution scaling would be much flatter.

The fastest data at 1080p Low (50 FPS) versus the far lower scores at 4K means the system should not be considered a 4K machine. Even the toggled-to-Low preset only holds 30 FPS at 2160p, which is barely at the threshold of comfortable flight-sim smoothness. A typical pilot flying over complex terrain would want to stay at either 1440p Medium (32 FPS) or 1080p Medium (39 FPS) to keep a solid frame rate while maintaining visual fidelity.

GPU Role

The Intel Arc B370 is not a discrete card but an integrated graphics block: the facts note its spec as IGP, its slot width as IGP, and its device-dependent display outputs. Its memory controller is listed as System Shared for size, type and bus width, with bandwidth described as System Dependent. That makes it equally dependent on system memory bandwidth and on the CPU’s own memory interface. The Core i5 13400F supports dual-channel DDR4/DDR5, but the exact bandwidth is not captured in the benchmark data, so the GPU is effectively limited by whatever the platform provides.

Inside the B370 the silicon provides 1280 shading units, 40 TMUs and 20 ROPs, with 10 ray-tracing cores and a raw FP32 throughput of 6.144 TFLOPS. The clock gradient is 300 MHz to 2400 MHz. Those are low-end figures—naturally aligned with a card that sits at the 5th percentile of all GPUs and averages only 1184 in the selective game-relevant benchmark. For comparison to other GPUs in its nearest-rival list, the B370 finishes within 1.4% of a very different family of graphics—ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M and AMD FirePro M2000. None of those are flying title understand exactly what kind of performance envelope we work with.

Given all this, no amount of game-optimizing can deliver a crash at 4K; the data shows 17–18 FPS on High and Ultra at 2160p, and no measured setting passes 30. The iGPU is not airing because it has to borrow system memory for both texture storage and frame buffer, which officially is at risk when the flight simulator streams huge terrain and scenery. The 10-core, 16-thread Intel Core i5 is not the stoppage—it holds the 77th percentile statewide. So the dataset says clearly: in this pairing the graphics part is the sole binding constraint.

Settings Recommendations

Given the frame rates, the best experience per settings come with an exclusive selection. At 1080p the available averages are Low 50, Medium 30, High 30 and Ultra 28. The leap from Medium at 39 to Low at 50 is worth noticing, because a flight simulator where pilots typically fly for areas of variance, many pilots will gladly trade those 11 frames for the 1080p visual jump. However, 1080p Medium (39 FPS) is still fully playable and retains more scenery detail, which is why the data shows Medium as the healthiest balance at that resolution.

At 1440p, Low holds 41 FPS while Medium sits at 32 FPS and High/Ultra remain at 25–23 average. With 1440p Medium min of 27 FPS, the range spans from 28 to 36, which does not leave ample headroom. Still, 32 FPS after the fastest performing route for flight sim. For the clearly better on-screen density, 1440p Medium would be the stronger option than 1080p Ultra (28 FPS), given the resolution jump outweighs the Ultra-preset visual bonus.

At 4K, only Low touches 30 FPS and even that average is tied to at a min value described. Medium and below land at 23 FPS or worse—18 on High and 17 on Ultra. Since only Low keeps the line at or above 30, 4K is only serviceable with everything removed. Pilots who care about visuals should instead drop resolution to 1440p Medium or 1080p Medium and gain 9–16 frames. The pattern from the Medium preset’s reported min/max—4K range 20 to 27, 1440p 27 to 36, 1080p 33 to 45—shows the width of the distribution barely changes at 1080p, while the 4K min sinks to 20, indicating that even on Medium the frame pacing is at very thin edge.

How This Combo Ranks

The combination ranks combined #3428 out of 3714. That is the bottom 10th of the database, which fits the GPU-centric story: the Arc B370’s 5th‑percentile position pulls the pairing down despite a relatively strong CPU. The Core i5-13400F’s own standing is much better—the 77th percentile, with average benchmark score 25292. Looking at the nearest rivals, it matches the AMD Ryzen 9 6900HS (25284, 0% delta), trails the Intel Core 5 120 (25362, −0.3) and AMD Ryzen 5 5600X3D (25365, −0.3) by roughly 0.3%, and beats the AMD Ryzen 7 6800H (25201) by 0.4%. Those deltas are tiny; the CPU is not the problem.

The GPU’s rival page reports a 1184 Steel Nomad score, while four peers—ATI Mobility Radeon HD 5570 (1186, −0.2% of the rivals), ATI Radeon HD 5770 (1237, −0.5), AMD Radeon HD 7650M (1192, −0.7) and AMD FirePro M2000 (1168, +1.4)—sit within a narrow 1.4% band. In other words, measured GPU has roughly the same performance as very old discrete parts. That explains why the overall combo rank is low even though the CPU itself slots among the same-level competitors. Upgraders should not waste time tuning the CPU; the data shows the i5-13400F is already at the expected level for a modern midrange chip, and the only meaningful benchmark looks at the GPU pairing would be to replace the Arc with something in a completely different performance segment.

FAQ

Q: Does the Intel Arc B370 have dedicated video memory?

A: No. The GPU’s memory size, type and bus width are all listed as System Shared, with bandwidth marked System Dependent. The part leverages the system’s main memory interface, where the CPU supports dual-channel DDR4/DDR5.

Q: What average frame rate do I get at 1080p Medium in Microsoft Flight Simulator?

A: 39 FPS on average, with a range from 33 to 45 FPS according to the measured rows.

Q: Can this combo handle 4K Ultra?

A: Not outside the 17 FPS average the data reports for 3840x2160 Ultra. The 4K Low preset drops to 30 FPS, with Medium at just 23 FPS, so any 4K playable configuration would require Low preset and even then only ties barely 30.

Q: Is the Core i5-13400F bottlenecking the GPU?

A: The data does not suggest that. The i5-13400F sits at the 77th percentile of all CPUs and its nearest rivals are within 0.4% of its average benchmark score. The GPU, in contrast, sits at the 5th percentile, which points to the graphics card as the limiting component.

Q: Which rows have the highest frame output?

A:** The 1080p Low preset shows a 50 FPS average—the highest average in the entire data. The same preset also offers the best average at 1440p (41) and at 4K (30), last.

Q: How reliable are the frame charts?

A:** The graph relies only on the Medium preset at each resolution for min/max; 1080p Medium has a 33–45 range, 1440p Medium 27–36, and 4K Medium 20–27. All other presets have averages but no reported min/max.
