# Microsoft Flight Simulator — Intel Core Ultra 5 225 + Intel Arc B570

This pairing of Intel's 10-core Arrow Lake desktop processor with the Arc B570 graphics card produces a system that sits near the bottom quartile of tested combinations in Microsoft Flight Simulator, ranking 2,988th out of 3,714 combos. The data reveals a configuration where the GPU's 10 GB frame buffer and 160-bit memory interface become the dominant constraint as resolution climbs, while the CPU's strong single-thread performance keeps playable frame rates within reach at 1080p and 1440p on lower presets.

Resolution Scaling

The measured FPS data shows a steep, predictable decline as resolution increases from 1920x1080 to 3840x2160, but the rate of that decline varies significantly by settings preset. At Low settings, the system delivers 86 FPS at 1080p, drops to 69 FPS at 1440p (a 19.8% reduction), and falls to 51 FPS at 4K (a further 26.1% reduction from 1440p). This pattern—where each resolution step costs roughly 20-26% of performance—indicates that at Low settings, the GPU is still the limiting factor, but the CPU is doing enough work to keep the pipeline relatively balanced.

At Medium settings, the scaling curve steepens noticeably. The system achieves 67 FPS at 1080p, 54 FPS at 1440p (a 19.4% drop), and 40 FPS at 4K (a 25.9% drop from 1440p). The min FPS values at Medium settings—57 FPS at 1080p, 46 FPS at 1440p, and 34 FPS at 4K—suggest that frame pacing becomes more erratic as resolution climbs, with the gap between average and minimum widening from 10 FPS at 1080p to 6 FPS at 4K. This indicates that the Arc B570's 10 GB memory buffer is starting to feel pressure from the higher-resolution textures.

High settings produce the most dramatic scaling penalty. The system runs at 50 FPS at 1080p, 41 FPS at 1440p (an 18% drop), and just 30 FPS at 4K (a 26.8% drop from 1440p). The jump from Medium to High at 4K costs 10 FPS, while the same settings change at 1080p costs 17 FPS—meaning the resolution penalty is relatively larger at higher settings. This is a classic sign of GPU-bound behavior where the B570's 11.52 TFLOPS of FP32 compute and 380.0 GB/s memory bandwidth are simply insufficient for the increased shading and texture work at 4K High.

Ultra settings push the system below playable thresholds at every resolution except 1080p, where it manages 48 FPS. At 1440p Ultra, the average drops to 39 FPS, and at 4K Ultra, it falls to 28 FPS—a 41.7% reduction from the 1080p result. The scaling from 1080p Ultra to 4K Ultra shows that the B570 loses more than a third of its performance when pixel count quadruples, which strongly suggests the GPU's memory subsystem—10 GB on a 160-bit bus with 380.0 GB/s bandwidth—is the bottleneck rather than the CPU.

GPU Role

The Intel Arc B570's specifications paint a clear picture of a mid-range graphics card that struggles with Microsoft Flight Simulator's demanding rendering pipeline at high resolutions. The GPU features 2,304 shading units, 144 TMUs, and 80 ROPs, with a boost clock of 2500 MHz. Its memory configuration—10 GB of GDDR6 on a 160-bit bus delivering 380.0 GB/s—is the most likely culprit for the performance cliffs observed at 4K with higher presets.

The B570's benchmark percentile of 65th among all GPUs places it in the upper half of available graphics cards, yet its nearest rivals in the GPU benchmark database include the NVIDIA GeForce RTX 3070 Mobile (0.1% higher average score) and the Intel Arc A750 (-0.1% lower). This suggests the B570 performs comparably to a last-generation desktop card or a mobile RTX 3070, but Microsoft Flight Simulator's heavy texture streaming and draw call overhead appear to amplify the B570's memory bandwidth limitations.

At 4K Ultra, the system's 28 FPS average is barely above the minimum threshold for playability, and the lack of min/max data for that preset (only the average is recorded) suggests the frame rate may be highly variable. The Medium preset at 4K, which does have min/max data (34-46 FPS), shows a 12 FPS spread—indicating that even at this moderate preset, the B570's frame time consistency suffers. This is consistent with the GPU's 150 W TDP and dual-slot cooler being adequate for the card's power draw but insufficient for sustained high-frequency operation under load.

The B570's ray tracing capabilities (18 RT cores) and DirectX 12 Ultimate support are present, but Microsoft Flight Simulator's primary bottleneck is likely the fill rate and memory bandwidth rather than RT performance. The GPU's pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s are respectable for the class, yet the 10 GB frame buffer becomes a constraint when the simulator loads high-resolution terrain and aircraft textures at 4K.

How This Combo Ranks

The combination of the Intel Core Ultra 5 225 and Intel Arc B570 ranks 2,988th out of 3,714 tested combos in Microsoft Flight Simulator, placing it in the bottom 19.5% of all configurations. This ranking is notably lower than what the individual component benchmarks might suggest—the CPU sits at the 85th percentile among all processors, and the GPU at the 65th percentile—indicating that this specific game pairing underperforms relative to the hardware's general capabilities.

The CPU's nearest rivals in the overall benchmark database include the AMD Ryzen 5 5600F (0% delta), AMD Ryzen 5 5500X3D (-0.2% delta), AMD Ryzen AI 7 PRO 450 (-0.4% delta), and Intel Core i9-12900T (-0.5% delta). These comparisons show the Ultra 5 225 is essentially performance-equivalent to a mid-range Ryzen 5000-series chip, yet the combo ranking suggests that in Microsoft Flight Simulator, the CPU's 10 cores and 10 threads may not be enough to overcome the GPU's limitations.

The GPU's nearest rivals—the RTX 3070 Mobile (0.1% delta), Arc A750 (-0.1% delta), Quadro M4000M (0.4% delta), and Radeon R9 M390X (-0.5% delta)—span a wide range of capabilities. That the B570's combo ranking lands in the bottom fifth suggests that Microsoft Flight Simulator is particularly sensitive to the B570's memory configuration or driver overhead, as the same GPU performs better relative to peers in other workloads.

The rank of 2,988 out of 3,714 means there are 726 tested combos that perform worse, but also 2,987 that perform better. For a system with a CPU at the 85th percentile and a GPU at the 65th percentile, this ranking is disappointing—it suggests the pairing is poorly optimized for this specific title, or that the game's engine is heavily dependent on certain hardware features the B570 lacks.

FAQ

Q: Is the Intel Core Ultra 5 225 bottlenecking the Arc B570 in this game?

A: No, the data indicates the GPU is the primary bottleneck. The CPU's 85th percentile ranking and strong single-thread score (3,655 in Cinebench R23) contrast with the combo's bottom-quintile rank (2,988 of 3,714), suggesting the B570's 10 GB memory and 380.0 GB/s bandwidth limit performance more than the CPU's 10 cores.

Q: What is the best resolution to play at with this combo?

A: The measured data shows 1080p is the only resolution where all four presets remain playable, with Low at 86 FPS, Medium at 67 FPS, High at 50 FPS, and Ultra at 48 FPS. At 1440p, only Low (69 FPS) and Medium (54 FPS) exceed 40 FPS, while 4K is only playable at Low (51 FPS) and Medium (40 FPS).

Q: How does the Arc B570 compare to its closest GPU rivals in terms of raw benchmark scores?

A: The B570's average benchmark score of 20,556 is nearly identical to the NVIDIA GeForce RTX 3070 Mobile (20,534, a 0.1% delta) and the Intel Arc A750 (20,582, a -0.1% delta). The Quadro M4000M scores 20,480 (0.4% below) and the Radeon R9 M390X scores 20,662 (0.5% above).

Q: Does the CPU's 10-core/10-thread configuration matter for this game?

A: The Core Ultra 5 225 has 10 cores and 10 threads with a boost clock of 4.90 GHz, and its Cinebench R23 multicore score of 25,891 places it at the 85th percentile. In Microsoft Flight Simulator, which is known to be single-thread bound, the CPU's single-core score of 3,655 likely keeps the system from being CPU-limited at lower resolutions.

Q: What causes the large FPS drop from 1080p to 4K at High settings?

A: The system drops from 50 FPS at 1080p High to 30 FPS at 4K High—a 40% reduction. This aligns with the B570's 10 GB GDDR6 memory and 160-bit bus, which struggle to feed the higher-resolution textures and increased pixel workload required at 3840x2160.

Q: Is the Ultra preset ever playable with this combo?

A: The data shows Ultra is only playable at 1080p with an average of 48 FPS. At 1440p Ultra, the average drops to 39 FPS, and at 4K Ultra, it falls to 28 FPS—both below the commonly accepted 40 FPS threshold for smooth flight simulation.

CPU Role

The Intel Core Ultra 5 225 brings 10 cores and 10 threads from the Arrow Lake architecture, built on a 3 nm process by TSMC with 17,800 million transistors on a 243 mm² die. Its base clock of 3.30 GHz boosts to 4.90 GHz, and the cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The processor supports DDR5 memory in dual-channel mode with 102.4 GB/s of memory bandwidth, and it sits at the 85th percentile among all CPUs in the benchmark database.

In synthetic benchmarks, the Ultra 5 225 achieves a Cinebench R23 multicore score of 25,891 and a single-core score of 3,655. Its PassMark multithread score of 30,459 and single-thread score of 4,412 indicate balanced performance, with the data encryption score of 22,285 and floating-point math score of 92,038 showing solid compute throughput. Compared to its nearest CPU rivals, the Ultra 5 225 is essentially tied with the AMD Ryzen 5 5600F (0% delta) and slightly behind the Ryzen 5 5500X3D (-0.2% delta) and Ryzen AI 7 PRO 450 (-0.4% delta).

In Microsoft Flight Simulator, the CPU's role appears secondary to the GPU. At 1080p Low, the system achieves 86 FPS—the highest measured result—which suggests the CPU can feed the B570 sufficiently at lower graphics loads. The fact that the 1080p Ultra result (48 FPS) is nearly identical to the 4K Low result (51 FPS) indicates that the CPU is not the limiting factor even at the lowest resolution with the highest preset. Instead, the B570's pixel throughput and memory bandwidth cap performance.

The CPU's 10 threads (no hyperthreading) may be a subtle constraint in a game like Microsoft Flight Simulator that spawns many background threads for terrain loading and AI traffic, but the data does not reveal a CPU bottleneck. The single-core performance, which is critical for the main game loop, appears adequate given that the system can hit 86 FPS at 1080p Low. The processor's 65 W TDP and Intel Socket 1851 platform suggest a power-efficient design that won't thermally throttle in most desktop chassis.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate floor. At 1080p, the Medium preset delivers 67 FPS average with a minimum of 57 FPS—this is the sweet spot for smooth gameplay without sacrificing too much visual quality. The High preset at 1080p (50 FPS average) is also acceptable, but the Ultra preset (48 FPS) offers only a marginal visual improvement over High for a significant performance risk if frame times spike.

At 1440p, the Medium preset (54 FPS average, 46 FPS minimum) is the most balanced choice, as it maintains playability while offering better image detail than Low (69 FPS). The High preset at 1440p (41 FPS) is borderline, and the Ultra preset (39 FPS) dips below the 40 FPS threshold that many flight sim enthusiasts consider the minimum for a smooth experience.

At 4K, the Low preset (51 FPS) is the only consistently playable option, with Medium (40 FPS average, 34 FPS minimum) sitting at the edge of playability. The High preset (30 FPS) and Ultra preset (28 FPS) are not recommended for anything beyond static screenshots or slow scenic flights.

For the best overall experience, the data suggests using 1080p Medium for general play, switching to 1440p Medium if a higher-resolution display is available, and reserving 4K for Low settings only. The min FPS values at Medium settings across all resolutions (57 FPS at 1080p, 46 FPS at 1440p, 34 FPS at 4K) show that this preset maintains a consistent frame rate, whereas the High and Ultra presets lack min/max data—likely due to more erratic performance.

Measured FPS Breakdown

The complete measured FPS dataset for Microsoft Flight Simulator with the Intel Core Ultra 5 225 and Intel Arc B570 is as follows:

1920x1080:

• Low: 86 FPS average
• Medium: 67 FPS average, 57 FPS minimum, 77 FPS maximum
• High: 50 FPS average
• Ultra: 48 FPS average

2560x1440:

• Low: 69 FPS average
• Medium: 54 FPS average, 46 FPS minimum, 62 FPS maximum
• High: 41 FPS average
• Ultra: 39 FPS average

3840x2160:

• Low: 51 FPS average
• Medium: 40 FPS average, 34 FPS minimum, 46 FPS maximum
• High: 30 FPS average
• Ultra: 28 FPS average

These 12 measured data points reveal a clear hierarchy: the system performs best at 1080p Low (86 FPS) and worst at 4K Ultra (28 FPS). The Medium preset is the only one with min/max data recorded at all three resolutions, which allows for a closer analysis of frame pacing. At 1080p Medium, the frame spread is 20 FPS (57-77), at 1440p Medium it's 16 FPS (46-62), and at 4K Medium it's 12 FPS (34-46). The narrowing spread at higher resolutions suggests that as the GPU becomes more heavily utilized, the frame rate stabilizes around a lower average rather than producing occasional high frames.

The delta between Low and Ultra at each resolution is consistent: 38 FPS at 1080p (86 vs 48), 30 FPS at 1440p (69 vs 39), and 23 FPS at 4K (51 vs 28). This indicates that the performance cost of Ultra settings is relatively constant in absolute terms, but the percentage cost increases with resolution—from 44.2% at 1080p to 54.9% at 4K. The data suggests that users who prioritize frame rate should stay at 1080p or 1440p with Medium settings, while those who value visual fidelity should accept the 30-40 FPS range at 4K Low or Medium.
